By daniellenierenberg

KENILWORTH, N.J. & WOODCLIFF LAKE, N.J.--(BUSINESS WIRE)--Merck (NYSE: MRK), known as MSD outside the United States and Canada, and Eisai today announced new data from analyses of two trials evaluating KEYTRUDA, Mercks anti-PD-1 therapy, plus LENVIMA, an orally available multiple receptor tyrosine kinase inhibitor discovered by Eisai. In the KEYNOTE-524/Study 116 and KEYNOTE-146/Study 111 trials, the KEYTRUDA plus LENVIMA combination demonstrated clinically meaningful objective response rates (ORR) in patients with unresectable hepatocellular carcinoma (HCC) with no prior systemic therapy and in patients with metastatic clear cell renal cell carcinoma (ccRCC) who progressed following immune checkpoint inhibitor therapy, respectively.

The tumor response rates demonstrated with KEYTRUDA plus LENVIMA in these studies underscore the potential of this combination regimen in certain types of hepatocellular and renal cell carcinoma, said Dr. Jonathan Cheng, Vice President, Oncology Clinical Research, Merck Research Laboratories. KEYTRUDA plus LENVIMA is an important pillar of our broad oncology research program, and we continue to advance the study of the combination across multiple types of cancers and stages of disease.

As data from our combination trials continue to read out, our enthusiasm for and belief in the potential of KEYTRUDA plus LENVIMA are strengthened by the growing body of evidence observed in multiple advanced cancers, said Dr. Takashi Owa, Chief Medicine Creation and Chief Discovery Officer, Oncology Business Group at Eisai. Our ongoing clinical study efforts on this combination exemplify our commitment to following the science and exploring possible solutions for patients affected by difficult-to-treat cancers.

Results from KEYNOTE-524/Study 116 (Abstract #4519) are being presented in a poster discussion session, and results from KEYNOTE-146/Study 111 (Abstract #5008) are being presented in an oral abstract session of the Virtual Scientific Program of the 2020 American Society of Clinical Oncology (ASCO) Annual Meeting.

KEYNOTE-524/Study 116 Trial Design and Data (Abstract #4519)

KEYNOTE-524/Study 116 (ClinicalTrials.gov, NCT03006926) is a Phase 1b, open-label, single-arm trial evaluating the KEYTRUDA plus LENVIMA combination in 100 patients with unresectable HCC with no prior systemic therapy. Patients were treated with KEYTRUDA 200 mg intravenously every three weeks in combination with LENVIMA 8 or 12 mg (based on baseline body weight 60 kilograms or 60 kilograms, respectively) orally once daily. The primary endpoints are ORR and duration of response (DOR) by modified Response Evaluation Criteria in Solid Tumors (mRECIST) and RECIST v1.1 per independent imaging review (IIR). Secondary endpoints include progression-free survival (PFS), time to progression (TTP) and overall survival (OS). At data cutoff (Oct. 31, 2019) and a median duration of follow-up of 10.6 months (95% CI: 9.2-11.5), 37 patients were still on study treatment (KEYTRUDA plus LENVIMA: n=34; LENVIMA only: n=3), and median duration of treatment exposure to the KEYTRUDA plus LENVIMA combination was 7.9 months (range: 0.2-31.1).

The final analysis of the studys primary endpoints showed the KEYTRUDA plus LENVIMA combination demonstrated an ORR of 36% (n=36) (95% CI: 26.6-46.2), with a complete response rate of 1% (n=1) and a partial response rate of 35% (n=35), and a median DOR of 12.6 months (95% CI: 6.9-not estimable [NE]), using RECIST v1.1 criteria per IIR. As assessed using mRECIST criteria per IIR, the KEYTRUDA plus LENVIMA combination demonstrated an ORR of 46% (n=46) (95% CI: 36.0-56.3), with a complete response rate of 11% (n=11) and a partial response rate of 35% (n=35), and a median DOR of 8.6 months (95% CI: 6.9-NE).

Treatment-related adverse events (TRAEs) led to discontinuation of KEYTRUDA and LENVIMA in 6% of patients, discontinuation of KEYTRUDA in 10% of patients, and discontinuation of LENVIMA in 14% of patients. Grade 3 TRAEs occurred in 67% of patients (Grade 3: 63%; Grade 4: 1%; Grade 5: 3%). There was one Grade 4 TRAE (leukopenia/neutropenia), and there were three Grade 5 treatment-related deaths (acute respiratory failure/acute respiratory distress syndrome, intestinal perforation and abnormal hepatic function; n=1 for each). The most common TRAEs of any grade (20%) were hypertension (36%), diarrhea (35%), fatigue (30%), decreased appetite (28%), hypothyroidism (25%), palmar-plantar erythrodysesthesia syndrome (23%), decreased weight (22%), dysphonia (21%), increased aspartate aminotransferase (20%) and proteinuria (20%).

KEYNOTE-146/Study 111 Trial Design and Data from the RCC Cohort (Abstract #5008)

KEYNOTE-146/Study 111 (ClinicalTrials.gov, NCT02501096) is a Phase 1b/2, open-label, single-arm trial evaluating the KEYTRUDA plus LENVIMA combination in patients with selected solid tumors. Results from the RCC cohort of the Phase 2 part of the study are based on 104 patients with metastatic ccRCC with disease progression following PD-1/PD-L1 immune checkpoint inhibitor therapy using RECIST v1.1 criteria. Patients were treated with KEYTRUDA 200 mg intravenously every three weeks in combination with LENVIMA 20 mg orally once daily until unacceptable toxicity or disease progression. The primary endpoint is ORR at week 24 by immune-related RECIST (irRECIST) per investigator review. Secondary endpoints include ORR, PFS, OS, safety and tolerability for a maximum of 35 cycles/treatments (approximately two years).

At data cutoff (Apr. 9, 2020), results from the Phase 2 part of the study showed the KEYTRUDA plus LENVIMA combination demonstrated an ORR at week 24 of 51% (95% CI: 41-61) by irRECIST per investigator review. As assessed by irRECIST per investigator review, ORR was 55% (95% CI: 45-65), with a partial response rate of 55%, a stable disease rate of 36% and a progressive disease rate of 5% (5% were not evaluable). Median DOR was 12 months (95% CI: 9-18). Median PFS was 11.7 months (95% CI: 9.4-17.7), and the 12-month PFS rate was 45% (95% CI: 32-57). Median OS was not reached (NR) (95% CI:16.7-NR), and the 12-month OS rate was 77% (95% CI: 67-85).

As assessed by RECIST v1.1 per investigator review, ORR was 52% (95% CI: 42-62), with a partial response rate of 52%, a stable disease rate of 38% and a progressive disease rate of 6% (5% were not evaluable). Median DOR was 12 months (95% CI: 9-18). Median PFS was 11.3 months (95% CI: 7.6-17.7), and the 12-month PFS rate was 44% (95% CI: 31-55).

TRAEs led to discontinuation of KEYTRUDA and LENVIMA in 15% of patients, discontinuation of KEYTRUDA in 12% of patients, and discontinuation of LENVIMA in 12% of patients (2% due to proteinuria). The most common TRAEs that led to dose reduction of LENVIMA were fatigue (14%), diarrhea (10%) and proteinuria (9%). Grade 4 TRAEs included lipase increased, diverticulitis, large intestine perforation and myocardial infarction, and there were two Grade 5 treatment-related deaths of upper gastrointestinal hemorrhage and sudden death. The most common TRAEs of any grade (20%) were fatigue (53%), diarrhea (46%), proteinuria (39%), dysphonia (35%), hypertension (34%), nausea (32%), stomatitis (32%), arthralgia (29%), decreased appetite (28%), palmar-plantar erythrodysesthesia syndrome (25%), hypothyroidism (23%) and headache (22%).

About KEYTRUDA (pembrolizumab) Injection, 100 mg

KEYTRUDA is an anti-PD-1 therapy that works by increasing the ability of the bodys immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.

Merck has the industrys largest immuno-oncology clinical research program. There are currently more than 1,200 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient's likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.

Selected Important Safety Information for KEYTRUDA

Immune-Mediated Pneumonitis

KEYTRUDA can cause immune-mediated pneumonitis, including fatal cases. Pneumonitis occurred in 3.4% (94/2799) of patients with various cancers receiving KEYTRUDA, including Grade 1 (0.8%), 2 (1.3%), 3 (0.9%), 4 (0.3%), and 5 (0.1%). Pneumonitis occurred in 8.2% (65/790) of NSCLC patients receiving KEYTRUDA as a single agent, including Grades 3-4 in 3.2% of patients, and occurred more frequently in patients with a history of prior thoracic radiation (17%) compared to those without (7.7%). Pneumonitis occurred in 6% (18/300) of HNSCC patients receiving KEYTRUDA as a single agent, including Grades 3-5 in 1.6% of patients, and occurred in 5.4% (15/276) of patients receiving KEYTRUDA in combination with platinum and FU as first-line therapy for advanced disease, including Grades 3-5 in 1.5% of patients.

Monitor patients for signs and symptoms of pneumonitis. Evaluate suspected pneumonitis with radiographic imaging. Administer corticosteroids for Grade 2 or greater pneumonitis. Withhold KEYTRUDA for Grade 2; permanently discontinue KEYTRUDA for Grade 3 or 4 or recurrent Grade 2 pneumonitis.

Immune-Mediated Colitis

KEYTRUDA can cause immune-mediated colitis. Colitis occurred in 1.7% (48/2799) of patients receiving KEYTRUDA, including Grade 2 (0.4%), 3 (1.1%), and 4 (<0.1%). Monitor patients for signs and symptoms of colitis. Administer corticosteroids for Grade 2 or greater colitis. Withhold KEYTRUDA for Grade 2 or 3; permanently discontinue KEYTRUDA for Grade 4 colitis.

Immune-Mediated Hepatitis (KEYTRUDA) and Hepatotoxicity (KEYTRUDA in Combination With Axitinib)

Immune-Mediated Hepatitis

KEYTRUDA can cause immune-mediated hepatitis. Hepatitis occurred in 0.7% (19/2799) of patients receiving KEYTRUDA, including Grade 2 (0.1%), 3 (0.4%), and 4 (<0.1%). Monitor patients for changes in liver function. Administer corticosteroids for Grade 2 or greater hepatitis and, based on severity of liver enzyme elevations, withhold or discontinue KEYTRUDA.

Hepatotoxicity in Combination With Axitinib

KEYTRUDA in combination with axitinib can cause hepatic toxicity with higher than expected frequencies of Grades 3 and 4 ALT and AST elevations compared to KEYTRUDA alone. With the combination of KEYTRUDA and axitinib, Grades 3 and 4 increased ALT (20%) and increased AST (13%) were seen. Monitor liver enzymes before initiation of and periodically throughout treatment. Consider more frequent monitoring of liver enzymes as compared to when the drugs are administered as single agents. For elevated liver enzymes, interrupt KEYTRUDA and axitinib, and consider administering corticosteroids as needed.

Immune-Mediated Endocrinopathies

KEYTRUDA can cause adrenal insufficiency (primary and secondary), hypophysitis, thyroid disorders, and type 1 diabetes mellitus. Adrenal insufficiency occurred in 0.8% (22/2799) of patients, including Grade 2 (0.3%), 3 (0.3%), and 4 (<0.1%). Hypophysitis occurred in 0.6% (17/2799) of patients, including Grade 2 (0.2%), 3 (0.3%), and 4 (<0.1%). Hypothyroidism occurred in 8.5% (237/2799) of patients, including Grade 2 (6.2%) and 3 (0.1%). The incidence of new or worsening hypothyroidism was higher in 1185 patients with HNSCC (16%) receiving KEYTRUDA, as a single agent or in combination with platinum and FU, including Grade 3 (0.3%) hypothyroidism. Hyperthyroidism occurred in 3.4% (96/2799) of patients, including Grade 2 (0.8%) and 3 (0.1%), and thyroiditis occurred in 0.6% (16/2799) of patients, including Grade 2 (0.3%). Type 1 diabetes mellitus, including diabetic ketoacidosis, occurred in 0.2% (6/2799) of patients.

Monitor patients for signs and symptoms of adrenal insufficiency, hypophysitis (including hypopituitarism), thyroid function (prior to and periodically during treatment), and hyperglycemia. For adrenal insufficiency or hypophysitis, administer corticosteroids and hormone replacement as clinically indicated. Withhold KEYTRUDA for Grade 2 adrenal insufficiency or hypophysitis and withhold or discontinue KEYTRUDA for Grade 3 or Grade 4 adrenal insufficiency or hypophysitis. Administer hormone replacement for hypothyroidism and manage hyperthyroidism with thionamides and beta-blockers as appropriate. Withhold or discontinue KEYTRUDA for Grade 3 or 4 hyperthyroidism. Administer insulin for type 1 diabetes, and withhold KEYTRUDA and administer antihyperglycemics in patients with severe hyperglycemia.

Immune-Mediated Nephritis and Renal Dysfunction

KEYTRUDA can cause immune-mediated nephritis. Nephritis occurred in 0.3% (9/2799) of patients receiving KEYTRUDA, including Grade 2 (0.1%), 3 (0.1%), and 4 (<0.1%) nephritis. Nephritis occurred in 1.7% (7/405) of patients receiving KEYTRUDA in combination with pemetrexed and platinum chemotherapy. Monitor patients for changes in renal function. Administer corticosteroids for Grade 2 or greater nephritis. Withhold KEYTRUDA for Grade 2; permanently discontinue for Grade 3 or 4 nephritis.

Immune-Mediated Skin Reactions

Immune-mediated rashes, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) (some cases with fatal outcome), exfoliative dermatitis, and bullous pemphigoid, can occur. Monitor patients for suspected severe skin reactions and based on the severity of the adverse reaction, withhold or permanently discontinue KEYTRUDA and administer corticosteroids. For signs or symptoms of SJS or TEN, withhold KEYTRUDA and refer the patient for specialized care for assessment and treatment. If SJS or TEN is confirmed, permanently discontinue KEYTRUDA.

Other Immune-Mediated Adverse Reactions

Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue in patients receiving KEYTRUDA and may also occur after discontinuation of treatment. For suspected immune-mediated adverse reactions, ensure adequate evaluation to confirm etiology or exclude other causes. Based on the severity of the adverse reaction, withhold KEYTRUDA and administer corticosteroids. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Based on limited data from clinical studies in patients whose immune-related adverse reactions could not be controlled with corticosteroid use, administration of other systemic immunosuppressants can be considered. Resume KEYTRUDA when the adverse reaction remains at Grade 1 or less following corticosteroid taper. Permanently discontinue KEYTRUDA for any Grade 3 immune-mediated adverse reaction that recurs and for any life-threatening immune-mediated adverse reaction.

The following clinically significant immune-mediated adverse reactions occurred in less than 1% (unless otherwise indicated) of 2799 patients: arthritis (1.5%), uveitis, myositis, Guillain-Barr syndrome, myasthenia gravis, vasculitis, pancreatitis, hemolytic anemia, sarcoidosis, and encephalitis. In addition, myelitis and myocarditis were reported in other clinical trials, including classical Hodgkin lymphoma, and postmarketing use.

Treatment with KEYTRUDA may increase the risk of rejection in solid organ transplant recipients. Consider the benefit of treatment vs the risk of possible organ rejection in these patients.

Infusion-Related Reactions

KEYTRUDA can cause severe or life-threatening infusion-related reactions, including hypersensitivity and anaphylaxis, which have been reported in 0.2% (6/2799) of patients. Monitor patients for signs and symptoms of infusion-related reactions. For Grade 3 or 4 reactions, stop infusion and permanently discontinue KEYTRUDA.

Complications of Allogeneic Hematopoietic Stem Cell Transplantation (HSCT)

Immune-mediated complications, including fatal events, occurred in patients who underwent allogeneic HSCT after treatment with KEYTRUDA. Of 23 patients with cHL who proceeded to allogeneic HSCT after KEYTRUDA, 6 (26%) developed graft-versus-host disease (GVHD) (1 fatal case) and 2 (9%) developed severe hepatic veno-occlusive disease (VOD) after reduced-intensity conditioning (1 fatal case). Cases of fatal hyperacute GVHD after allogeneic HSCT have also been reported in patients with lymphoma who received a PD-1 receptorblocking antibody before transplantation. Follow patients closely for early evidence of transplant-related complications such as hyperacute graft-versus-host disease (GVHD), Grade 3 to 4 acute GVHD, steroid-requiring febrile syndrome, hepatic veno-occlusive disease (VOD), and other immune-mediated adverse reactions.

In patients with a history of allogeneic HSCT, acute GVHD (including fatal GVHD) has been reported after treatment with KEYTRUDA. Patients who experienced GVHD after their transplant procedure may be at increased risk for GVHD after KEYTRUDA. Consider the benefit of KEYTRUDA vs the risk of GVHD in these patients.

Increased Mortality in Patients With Multiple Myeloma

In trials in patients with multiple myeloma, the addition of KEYTRUDA to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of these patients with a PD-1 or PD-L1 blocking antibody in this combination is not recommended outside of controlled trials.

Embryofetal Toxicity

Based on its mechanism of action, KEYTRUDA can cause fetal harm when administered to a pregnant woman. Advise women of this potential risk. In females of reproductive potential, verify pregnancy status prior to initiating KEYTRUDA and advise them to use effective contraception during treatment and for 4 months after the last dose.

ORLANDO, Fla.--(BUSINESS WIRE)--Hesperos Inc., pioneers of the Human-on-a-Chip in vitro system, today announced a new peer-reviewed publication that describes how the companys functional Human-on-a-Chip system can be used as a drug discovery platform to identify therapeutic interventions targeting the preclinical stages of Alzheimers disease (AD) and mild cognitive impairment (MCI). The manuscript, titled A human induced pluripotent stem cell-derived cortical neuron human-on-a-chip system to study A42 and tau-induced pathophysiological effects on long-term potentiation, was published this week in Alzheimer's & Dementia: Translational Research & Clinical Interventions. The work was conducted in collaboration with the University of Central Florida and with David G. Morgan, Ph.D., Professor of Translational Neuroscience at Michigan State University, and expert in AD pathology.

To date, more than 100 potential therapeutics in development for AD have been abandoned or failed during clinical trials. These therapeutics relied on research conducted in preclinical animal studies, which often are unable to accurately capture the full spectrum of the human disease phenotype, including differences in drug metabolism and excretion between humans and animals. Therefore, there is a need for human models, especially those that accurately recapitulate the functional impairments during the preclinical phases of AD and MCI.

Hesperos offers a breakthrough technology that provides a human cell-based assay based on cognitive function metrics to evaluate drugs designed to restore cognition at early stages of the Alzheimers continuum, said Dr. Morgan. This system can serve as a novel drug discovery platform to identify compounds that rescue or alleviate the initial neuronal deficits caused by A1-42 and/or tau oligomers, which is a main focus of clinical trials.

In 2018, Hesperos received a Phase I Small Business Innovation Research (SBIR) grant from the National Institute on Aging (NIA) division within the US National Institutes of Health (NIH) to help create a new multi-organ human-on-a-chip model for testing AD drugs. Research conducted under this grant included a study to assess therapeutic interventions based on functional changes in neurons, not neuronal death.

In the recent Alzheimer's & Dementia publication, Hesperos describes its in vitro human induced pluripotent stem cell (iPSC)-derived cortical neuron human-on-a-chip system for the evaluation of neuron morphology and function after exposure to toxic A and tau oligomers as well as brain extracts from AD transgenic mouse models.

Researchers are now focusing on biomarker development and therapeutic intervention before symptoms arise in AD and MCI, said James Hickman, Ph.D., Chief Scientist at Hesperos and Professor at the University of Central Florida. By studying functional disruption without extensive cell loss, we now have a screening methodology for drugs that could potentially evaluate therapeutic efficacy even before the neurodegeneration in MCI and AD occurs.

The researchers found that compared to controls, treatment with toxic A and tau oligomers or brain extracts on the iPSC cortical neurons significantly impaired information processing as demonstrated by reduction in high-frequency stimulation-induced long-term potentiation (LTP), a process that is thought to underlie memory formation and learning. Additionally, oligomer and brain extract exposure led to dysfunction in iPSC cortical neuron electrophysiological activity, including decreases in ion current and action potential firing.

While exposure to the toxic oligomers and brain extracts caused morphological defects in the iPSC cortical neurons, there was no significant loss in cell viability.

Clinical success for AD therapies has been challenging since preclinical animal studies often do not translate to humans, said Michael L. Shuler, Ph.D., Chief Executive Officer of Hesperos. With our recent study, we are now one step closer in developing an AD multi-organ model to better evaluate drug metabolism in the liver, penetration through the blood-brain barrier and the effects on neuronal cells.

About Alzheimers Disease/Preclinical Stage AD

AD is a progressive disease that is characterized by memory loss and deterioration of cognitive function. Preclinical AD is the first stage of the disease, and it begins long before any symptoms become apparent. It is thought that symptoms do not manifest until there is a significant death of neuronal cells, which is caused by the aggregation of toxic amyloid beta (A) and tau oligomers, typically during the earliest stages of the disease. Unfortunately, treatment after the diagnosis of MCI may be too late to reverse or modify disease progression.

Merck’s KEYTRUDA (pembrolizumab) Superior to Standard of Care Chemotherapy in Patients with MSI-H Colorectal Cancer – BioSpace

By daniellenierenberg

For many years, the standard of care for the first-line treatment of patients with MSI-H colorectal cancer has been the combination of mFOLFOX6 plus bevacizumab. This is the first time a single-agent, anti-PD-1 therapy demonstrated a superior, statistically significant and clinically meaningful improvement in progression-free survival compared to chemotherapy for these patients, said Dr. Roy Baynes, senior vice president and head of global clinical development, chief medical officer, Merck Research Laboratories. There is an unmet need for new treatment options in the first-line setting that may provide sustained, long-term improvements in outcomes for patients with MSI-H colorectal cancer. We are grateful to have the opportunity to present these practice-changing findings at the plenary session of this years ASCO.

KEYTRUDA monotherapy significantly reduced the risk of disease progression or death by 40% versus standard of care chemotherapy, with fewer treatment-related adverse events observed, in patients with MSI-H metastatic colorectal cancer. KEYTRUDA also demonstrated a long-term, durable response that lasted over two years for those who responded to treatment, said Thierry Andre, MD, professor of medical oncology, Sorbonne University, and Head of the Medical Oncology Department in St. Antoine Hospital, Assistance Publique Hpitaux de Paris. Data from KEYNOTE-177 show that KEYTRUDA monotherapy has the potential to become the new standard of care for first-line treatment of patients with MSI-H metastatic colorectal cancer.

In May 2017, KEYTRUDA became the first cancer therapy approved by the U.S. Food and Drug Administration for use based on a biomarker, regardless of tumor type, in previously treated patients with MSI-H or dMMR solid tumors.

As announced, more than 80 abstracts in nearly 20 types of solid tumors and blood cancers will be presented from Mercks broad oncology portfolio and investigational pipeline at ASCO. A compendium of presentations and posters of Merck-led studies will be posted by Merck on Friday, May 29 at 8 a.m. ET. Follow Merck on Twitter via @Merck and keep up to date with ASCO news and updates by using the hashtag #ASCO20.

KEYNOTE-177 Study Design and Additional Data (Abstract #LBA4)

KEYNOTE-177 is a randomized, open-label, Phase 3 trial evaluating KEYTRUDA monotherapy versus standard of care chemotherapy for the first-line treatment of patients with MSI-H or dMMR metastatic colorectal cancer (ClinicalTrials.gov, NCT02563002). The dual primary endpoints are PFS and OS. The study enrolled 307 patients, who were randomized to receive either KEYTRUDA (200 mg intravenously on Day 1 of each three-week cycle for up to 35 cycles) or investigators choice of one of the following chemotherapy-based regimens: mFOLFOX6; mFOLFOX6 plus bevacizumab (5 mg/kg IV on Day 1 of each two-week cycle); mFOLFOX6 plus cetuximab (400 mg/m2 IV, then 250 mg/m2 weekly in each two-week cycle); FOLFIRI; FOLFIRI plus bevacizumab (5 mg/kg IV on Day 1 of each two-week cycle); or FOLFIRI plus cetuximab (400 mg/m2 IV, then 250 mg/m2 weekly in each two-week cycle).

In this study, KEYTRUDA demonstrated a statistically significant and clinically meaningful improvement in PFS (HR=0.60 [95% CI, 0.45-0.80; p=0.0002]) and showed a median PFS of 16.5 months compared with 8.2 months for patients treated with chemotherapy. The two-year PFS rate was 48% with KEYTRUDA versus 19% with chemotherapy. The ORR was 43.8% with KEYTRUDA versus 33.1% with chemotherapy, with a complete response observed in 11.1% and 3.9% of patients, respectively; partial responses were observed in 32.7% and 29.2% of patients, respectively. Median duration of response was not reached with KEYTRUDA (range, 2.3+ to 41.4+) versus 10.6 months with chemotherapy (range, 2.8 to 37.5+). Additionally, 83% of patients had durable responses lasting at least two years with KEYTRUDA versus 35% with chemotherapy. In the study, 59% of patients in the intent-to-treat population received subsequent anti-PD-1/PD-L1 therapy after discontinuing study treatment in the chemotherapy arm.

The safety profile of KEYTRUDA demonstrated a lower incidence of Grade 3 treatment-related adverse events (AEs) versus chemotherapy (22% versus 66%, respectively), and no new toxicities were observed. Immune-mediated AEs and infusion reactions occurred in 31% of patients receiving KEYTRUDA and 13% of patients receiving chemotherapy. The most commonly reported immune-mediated AEswere hypothyroidism (12%) and colitis (7%) with KEYTRUDA, and infusion reactions (8%) with chemotherapy.

Merck Investor Event

Merck will hold a virtual investor event in conjunction with the ASCO Annual Meeting on Tuesday, June 2 at 2 p.m. ET. Details will be provided at a date closer to the event at http://investors.merck.com/home/default.aspx.

About Microsatellite Instability High (MSI-H)

Microsatellite instability (or MSI) is defined by the National Cancer Institute as a change that occurs in the DNA of certain cells (such as tumor cells) in which the number of repeats of microsatellites (short, repeated sequences of DNA) is different from the number of repeats that was in the DNA when it was inherited. The cause of MSI may be a defect in the ability to repair mistakes made when DNA is copied in the cell. This defect is also referred to as mismatch repair deficiency (dMMR). It is estimated that approximately 5-15% of colorectal cancer patients have tumors that score as either MSI-H or dMMR when testing is performed.

About Colorectal Cancer

Colorectal cancer starts in the colon or the rectum, and these cancers are referred to as colon cancer and rectal cancer depending on where the cancer starts. Colorectal cancer often begins with growths on the inner lining of the colon or rectum called polyps, which can change into cancer over time. Colorectal cancer is the third most commonly diagnosed cancer and the second most common cause of cancer-related death worldwide. It is estimated there were nearly 850,000 new cases of colorectal cancer and more than 880,000 deaths from the disease globally in 2018. In the United States, it is estimated there will be nearly 105,000 new cases of colon cancer and more than 43,000 new cases of rectal cancer, resulting in more than 53,000 deaths from colorectal cancer in 2020. The five-year survival rates for advanced/metastatic colon cancer and rectal cancer (stage IV) are estimated to be 14% and 15%, respectively.

Research at MDI Biological Laboratory explores novel pathways of regeneration and tumorigenesis – Bangor Daily News

By daniellenierenberg

BAR HARBOR Research by scientists at the MDI Biological Laboratoryis opening up new approaches to promoting tissue regeneration in organs damaged by disease or injury.

In recent years, research in regenerative biology has focused on stem cell therapies that reprogram the bodys own cells to replace damaged tissue, which is a complicated process because it involves turning genes in the cells nucleus on and off.

A recent paper in the journal Genetics by MDI Biological Laboratory scientist Elisabeth Marnik, Ph.D., a postdoctoral fellow in the laboratory of Dustin Updike, Ph.D., offers insight into an alternate pathway to regeneration: by recreating the properties of germ cells.

Germ cells, which are the precursors to the sperm and egg, are considered immortal because they are the only cells in the body with the potential to create an entirely new organism. The stem cell-like ability of germ cells to turn into any type of cell is called totipotency.

By getting a handle on what makes germ cells totipotent, we can promote regeneration by unlocking the stem cell-like properties of other cell types, said Updike. Our research shows that such cells can be reprogrammed by manipulating their cytoplasmic composition and chemistry, which would seem to be safer and easier than changing the DNA within a cells nucleus.

Using the tiny, soil-dwelling nematode worm, C. elegans, as a model, the Updike lab studies organelles called germ granules that reside in the cytoplasm (the contents of the cell outside of the nucleus) of germ cells. These organelles, which are conserved from nematodes to humans, are one of the keys to the remarkable attributes of germ cells, including the ability to differentiate into other types of cells.

In their recent paper entitled Germline Maintenance Through the Multifaceted Activities of GLH/Vasa in Caenorhabditis elegans P Granules, Updike and his team describe the intriguing and elusive role of Vasa proteins within germ granules in determining whether a cell is destined to become a germ cell with totipotent capabilities or a specific type of cell, like those that comprise muscle, nerves or skin.

Because of the role of Vasa proteins in preserving totipotency, an increased understanding of how such proteins work could lead to unprecedented approaches to de-differentiating cell types to promote regeneration; or alternatively, to new methods to turn off totipotency when it is no longer desirable, as in the case of cancer.

The increase in chronic and degenerative diseases caused by the aging of the population is driving demand for new therapies, said MDI Biological Laboratory President Hermann Haller, M.D. Dustins research on germ granules offers another route to repairing damaged tissues and organs in cases where therapeutic options are limited or non-existent, as well as an increased understanding of cancer.

Because of the complexity of the cellular chemistry, research on Vasa and other proteins found in germ granules is often overlooked, but that is rapidly changing especially among pharmaceutical companies as more scientists realize the impact and potential of such research, not only for regenerative medicine but also for an understanding of tumorigenesis, or cancer development, Updike said.

Recent research has found that some cancers are accompanied by the mis-expression of germ granule proteins, which are normally found only in germ cells. The mis-expression of these germ-granule proteins seems to promote the immortal properties of germ cells, and consequently tumorigenesis, with some germ-granule proteins now serving as prognosis markers for different types of cancer, Updike said.

Updike is a former postdoctoral researcher in the laboratory of Susan Strome, Ph.D., at University of California, Santa Cruz. Strome, who was inducted into the National Academy of Sciences last year, first discovered P granules more than 30 years ago. She credits Updike, who has published several seminal papers on the subject, with great imagination, determination and excellent technical skill in the pursuit of his goal of elucidating the function and biochemistry of these tiny organelles.

The lead author of the new study from the Updike laboratory, Elisabeth A. Marnik, Ph.D., will be launching her own laboratory at Husson University in Bangor, Maine, this fall. Other contributors include J. Heath Fuqua, Catherine S. Sharp, Jesse D. Rochester, Emily L. Xu and Sarah E. Holbrook. Their research was conducted at the Kathryn W. Davis Center for Regenerative Biology and Medicine at the MDI Biological Laboratory.

Updikes research is supported by a grant (R01 GM-113933) from the National Institute of General Medical Sciences (NIGMS), an institute of the National Institutes of Health (NIH). The equipment and cores used for part of the study were supported by NIGMS-NIH Centers of Biomedical Research Excellence and IDeA Networks of Biomedical Research Excellence grants P20 GM-104318 and P20 GM-203423, respectively.

We aim to improve human health and healthspan by uncovering basic mechanisms of tissue repair, aging and regeneration, translating our discoveries for the benefit of society and developing the next generation of scientific leaders. For more information, please visitmdibl.org.

Function of Bone Marrow: What Is Bone Marrow, and What …

By daniellenierenberg

The bones of the skeletal system serve many important functions for the body, from giving your body support to allowing you to move. They also play an important role in blood cell production and fat storage.

Bone marrow is the spongy or viscous tissue that fills the inside of your bones. There are actually two types of bone marrow:

Read on to learn more about different functions of red and yellow bone marrow as well as the conditions that affect bone marrow.

Red bone marrow is involved in hematopoiesis. This is another name for blood cell production. Hematopoietic stem cells that are found in red bone marrow can develop into a variety of different blood cells, including:

Newly produced blood cells enter your bloodstream through vessels called sinusoids.

As you age, your red bone marrow is gradually replaced with yellow bone marrow. And by adulthood, red bone marrow can be found only in a handful of bones, including the:

Yellow bone marrow is involved in the storage of fats. The fats in yellow bone marrow are stored in cells called adipocytes. This fat can be used as an energy source as needed.

Yellow bone marrow also contains mesenchymal stem cells. These are cells that can develop into bone, fat, cartilage, or muscle cells.

Remember, over time, yellow bone marrow starts to replace red bone marrow. So, most bones in an adult body contain yellow bone marrow.

Bone marrow is crucial for producing blood cells. Therefore, a range of blood-related conditions involve issues with bone marrow.

Many of these conditions affect the numbers of blood cells produced in bone marrow. This causes them to share many common symptoms, including:

Heres a look at some specific conditions involving bone marrow issues.

Leukemia is a type of cancer that can affect both your bone marrow and lymphatic system.

It happens when blood cells get mutations in their DNA. This causes them to grow and divide more rapidly than healthy blood cells. Over time, these cells start to crowd out the healthy cells in your bone marrow.

Leukemia is classified as either acute or chronic, depending on how fast it progresses. Its further broken down by the type of white blood cells it involves.

Myelogenous leukemia involves red blood cells, white blood cells, and platelets. Lymphocytic leukemia involves lymphocytes, a specific type of white blood cell.

Some of the major types of leukemia include:

Theres no clear cause of leukemia, but certain things can increase your risk, including:

Aplastic anemia occurs when bone marrow doesnt produce enough new blood cells. It occurs from damage to the stem cells of bone marrow. This makes it harder from them to grow and develop into new blood cells.

This damage can be either:

Myeloproliferative disorders happen when the stem cells in bone marrow grow abnormally. This can lead to increased numbers of a specific type of blood cell.

There are several types of myeloproliferative disorders, including:

Bone marrow is found in the bones throughout your body. There are two types of bone marrow. Red bone marrow is involved in production of blood cells, while yellow marrow is important for fat storage. As you age, yellow bone marrow replaces red bone marrow.

Shanghai Cell Therapy Group Launches Collaboration with USC researcher to Improve the ex vivo Expansion of Hematopoietic Stem Cells for Clinical…

By daniellenierenberg

SHANGHAI, May27, 2020 /PRNewswire/ -- Shanghai Cell Therapy Group (SHCell) recently entered intoa six-year research collaborative project with Professor Qi-Long Ying from the University of Southern California (USC). Through the project, sponsored by $3.6 million from the Baize Plan Fund, the Ying laboratory aims to develop conditions for the long-term ex vivo expansion of mouse and human hematopoietic stem and progenitor cells.

"Hematopoietic stem cells, or HSCs, are found in the bone marrow of adults," said Professor Qijun Qian, CEO of Shanghai Cell Therapy Group. "HSCs have the ability for long-term self-renewal and differentiation into various types of mature blood cells, and for rebuilding normal hematopoiesis and immune function in patients. They also have enormous potential to treat diseases, including tumors, autoimmune diseases, severe infectious disease, and inherited blood diseases, and to combat the effects of aging."

This research project will be conducted and supervised by Professor Qi-Long Ying, a Professor of Stem Cell Biology and Regenerative Medicine at the Keck School of Medicine of USC. Professor Ying's pioneering stem cell research has won international acclaim, including the 2016 McEwen Award for Innovation, the highest honor in the field.

"We'll develop and optimize culture conditions for the long-term ex vivo expansion of HSCs," said Professor Ying. "We'll also test combinations of basal media, small molecules, cytokines and growth factors, and characterize ex vivo expanded hematopoietic stem and progenitor cells. These cells will then be genetically modified and tested for their potential to treat different diseases, including blood disorders and cancers."

Professor Andrew P. McMahon, Director of Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research of USC, added: "Stem cell biology represents an exciting area in medicine with great therapeutic potential. I am delighted SHCell is supporting Professor Ying. A breakthrough in the ability to propagate and manipulate HSCs will have lasting clinical significance."

The project also plans to build animal models of different blood diseases and cancers and test the safety and effectiveness of genetically modified hematopoietic stem and progenitor cells before clinical translation. SHCell will actively explore clinical applications of hematopoietic stem and progenitor cells in the treatment of cancers or blood diseases.

As SHCell's first overseas collaboration, this project aims to advance the goals of the Baize Plan: to provide first-class cell treatments and cell therapies at an affordable price to cure cancer and increase life expectancy. SHCell hopes that this project will also accelerate original scientific breakthroughs in the stem cell field.

Shanghai Cell Therapy Group

Founded in 2013, Shanghai Cell Therapeutics Group Co., Ltd is located at the Shanghai Municipal Engineering and Technology Research Center, which was established by the Shanghai Science and Technology Commission. With a mission of "changing the length and abundance of life with cell therapy", SHCell has created a closed-loop industrial chain and an integrated platform for cell treatment and cell therapy. It comprises cell storage, cell drug research and cell clinical transformation with cell therapy as its core business.

The Baize Plan was proposed in 2016 by Wu Mengchao, an Academician of the Chinese Academy of Sciences (CAS) and initiated by Professor Qian, aiming to provide first-class cell treatments and cell therapies at an affordable price with the goal of curing cancers and increasing life expectancy. The Baize Plan Fund was created by the Shanghai Cell Therapy Group to realize the vision of the Baize Plan.

University of Southern California (USC)

Founded in 1880, the University of Southern California is one of the world's leading educational and research institutions, and also the oldest private research university in California. Located in the heart of Los Angeles, the University of Southern California comprises 23 schools and units, and students are encouraged to explore different fields of study.

On the Origins of Modern Biology and the Fantastic: Part 19 Nalo Hopkinson and Stem Cell Research – tor.com

By daniellenierenberg

She just wanted to be somewhere safe, somewhere familiar, where people looked and spoke like her and she could stand to eat the food. Midnight Robber by Nalo Hopkinson

Midnight Robber (2000) is about a woman, divided. Raised on the high-tech utopian planet of Touissant, Tan-Tan grows up on a planet populated by the descendants of a Caribbean diaspora, where all labor is performed by an all-seeing AI. But when she is exiled to Touissants parallel universe twin planet, the no-tech New Half-Way Tree, with her sexually abusive father, she becomes divided between good and evil Tan-Tans. To make herself and New Half-Way Tree whole, she adopts the persona of the legendary Robber Queen and becomes a legend herself. It is a wondrous blend of science fictional tropes and Caribbean mythology written in a Caribbean vernacular which vividly recalls the history of slavery and imperialism that shaped Touissant and its people, published at a time when diverse voices and perspectives within science fiction were blossoming.

Science fiction has long been dominated by white, Western perspectives. Vernes tech-forward adventures and Wells sociological allegories established two distinctive styles, but still centered on white imperialism and class struggle. Subsequent futures depicted in Verne-like pulp and Golden Age stories, where lone white heroes conquered evil powers or alien planets, mirrored colonialist history and the subjugation of non-white races. The civil rights era saw the incorporation of more Wellsian sociological concerns, and an increase in the number of non-white faces in the future, but they were often tokensparts of a dominant white monoculture. Important figures that presaged modern diversity included Star Treks Lieutenant Uhura, played by Nichelle Nichols. Nichols was the first black woman to play a non-servant character on TV; though her glorified secretary role frustrated Nichols, her presence was a political act, showing there was space for black people in the future.

Another key figure was the musician and poet Sun Ra, who laid the aesthetic foundation for what would become known as the Afrofuturist movement (the term coined by Mark Dery in a 1994 essay), which showed pride in black history and imagined the future through a black cultural lens. Within science fiction, the foundational work of Samuel Delany and Octavia Butler painted realistic futures in which the histories and cultural differences of people of color had a place. Finally, an important modern figure in the decentralization of the dominant Western perspective is Nalo Hopkinson.

A similarly long-standing paradigm lies at the heart of biology, extending back to Darwins theoretical and Mendels practical frameworks for the evolution of genetic traits via natural selection. Our natures werent determined by experience, as Lamarck posited, but by genes. Therefore, genes determine our reproductive fitness, and if we can understand genes, we might take our futures into our own hands to better treat disease and ease human suffering. This theory was tragically over-applied, even by Darwin, who in Descent of Man (1871) conflated culture with biology, assuming the Wests conquest of indigenous cultures meant white people were genetically superior. After the Nazis committed genocide in the name of an all-white future, ideas and practices based in eugenics declined, as biological understanding of genes matured. The Central Dogma of the 60s maintained the idea of a mechanistic meaning of life, as advances in genetic engineering and the age of genomics enabled our greatest understanding yet of how genes and disease work. The last major barrier between us and our transhumanist future therefore involved understanding how genes determine cellular identity, and as well see, key figures in answering that question are stem cells.

Hopkinson was born December 20, 1960 in Kingston, Jamaica. Her mother was a library technician and her father wrote, taught, and acted. Growing up, Hopkinson was immersed in the Caribbean literary scene, fed on a steady diet of theater, dance, readings, and visual arts exhibitions. She loved to readfrom folklore, to classical literature, to Kurt Vonnegutand loved science fiction, from Spock and Uhura on Star Trek, to Le Guin, James Tiptree Jr., and Delany. Despite being surrounded by a vibrant writing community, it didnt occur to her to become a writer herself. What they were writing was poetry and mimetic fiction, Hopkinson said, whereas I was reading science fiction and fantasy. It wasnt until I was 16 and stumbled upon an anthology of stories written at the Clarion Science Fiction Workshop that I realized there were places where you could be taught how to write fiction. Growing up, her family moved often, from Jamaica to Guyana to Trinidad and back, but in 1977, they moved to Toronto to get treatment for her fathers chronic kidney disease, and Hopkinson suddenly became a minority, thousands of miles from home.

Development can be described as an orderly alienation. In mammals, zygotes divide and subsets of cells become functionally specialized into, say, neurons or liver cells. Following the discovery of DNA as the genetic material in the 1950s, a question arose: did dividing cells retain all genes from the zygote, or were genes lost as it specialized? British embryologist John Gurdon addressed this question in a series of experiments in the 60s using frogs. Gurdon transplanted nuclei from varyingly differentiated cells into oocytes stripped of their genetic material to see if a new frog was made. He found the more differentiated a cell was, the lower the chance of success, but the successes confirmed that no genetic material was lost. Meanwhile, Canadian biologists Ernest McCulloch and James Till were transplanting bone marrow to treat irradiated mice when they noticed it caused lumps in the mices spleens, and the number of lumps correlated with the cellular dosage. Their lab subsequently demonstrated that each lump was a clonal colony from a single donor cell, and a subset of those cells was self-renewing and could form further colonies of any blood cell type. They had discovered hematopoietic stem cells. In 1981 the first embryonic stem cells (ESCs) from mice were successfully propagated in culture by British biologist Martin Evans, winning him the Nobel Prize in 2007. This breakthrough allowed biologists to alter genes in ESCs, then use Gurdons technique to create transgenic mice with that alteration in every cellcreating the first animal models of disease.

In 1982, one year after Evans discovery, Hopkinson graduated with honors from York University. She worked in the arts, as a library clerk, government culture research officer, and grants officer for the Toronto Arts Council, but wouldnt begin publishing her own fiction until she was 34. [I had been] politicized by feminist and Caribbean literature into valuing writing that spoke of particular cultural experiences of living under colonialism/patriarchy, and also of writing in ones own vernacular speech, Hopkinson said. In other words, I had models for strong fiction, and I knew intimately the body of work to which I would be responding. Then I discovered that Delany was a black man, which opened up a space for me in SF/F that I hadnt known I needed. She sought out more science fiction by black authors and found Butler, Charles Saunders, and Steven Barnes. Then the famous feminist science fiction author and editor Judy Merril offered an evening course in writing science fiction through a Toronto college, Hopkinson said. The course never ran, but it prompted me to write my first adult attempt at a science fiction story. Judy met once with the handful of us she would have accepted into the course and showed us how to run our own writing workshop without her. Hopkinsons dream of attending Clarion came true in 1995, with Delany as an instructor. Her early short stories channeled her love of myth and folklore, and her first book, written in Caribbean dialect, married Caribbean myth to the science fictional trappings of black market organ harvesting. Brown Girl in the Ring (1998) follows a young single mother as shes torn between her ancestral culture and modern life in a post-economic collapse Toronto. It won the Aspect and Locus Awards for Best First Novel, and Hopkinson was awarded the John W. Campbell Award for Best New Writer.

In 1996, Dolly the Sheep was created using Gurdons technique to determine if mammalian cells also could revert to more a more primitive, pluripotent state. Widespread animal cloning attempts soon followed, (something Hopkinson used as a science fictional element in Brown Girl) but it was inefficient, and often produced abnormal animals. Ideas of human cloning captured the public imagination as stem cell research exploded onto the scene. One ready source for human ESC (hESC) materials was from embryos which would otherwise be destroyed following in vitro fertilization (IVF) but the U.S. passed the Dickey-Wicker Amendment prohibited federal funding of research that destroyed such embryos. Nevertheless, in 1998 Wisconsin researcher James Thomson, using private funding, successfully isolated and cultured hESCs. Soon after, researchers around the world figured out how to nudge cells down different lineages, with ideas that transplant rejection and genetic disease would soon become things of the past, sliding neatly into the hole that the failure of genetic engineering techniques had left behind. But another blow to the stem cell research community came in 2001, when President Bushs stem cell ban limited research in the U.S. to nineteen existing cell lines.

In the late 1990s, another piece of technology capturing the public imagination was the internet, which promised to bring the world together in unprecedented ways. One such way was through private listservs, the kind used by writer and academic Alondra Nelson to create a space for students and artists to explore Afrofuturist ideas about technology, space, freedom, culture and art with science fiction at the center. It was wonderful, Hopkinson said. It gave me a place to talk and debate with like-minded people about the conjunction of blackness and science fiction without being shouted down by white men or having to teach Racism 101. Connections create communities, which in turn create movements, and in 1999, Delanys essay, Racism and Science Fiction, prompted a call for more meaningful discussions around race in the SF community. In response, Hopkinson became a co-founder of the Carl Brandon society, which works to increase awareness and representation of people of color in the community.

Hopkinsons second novel, Robber, was a breakthrough success and was nominated for Hugo, Nebula, and Tiptree Awards. She would also release Skin Folk (2001), a collection of stories in which mythical figures of West African and Afro-Caribbean culture walk among us, which would win the World Fantasy Award and was selected as one ofThe New York Times Best Books of the Year. Hopkinson also obtained masters degree in fiction writing (which helped alleviate U.S. border hassles when traveling for speaking engagements) during which she wrote The Salt Roads (2003). I knew it would take a level of research, focus and concentration I was struggling to maintain, Hopkinson said. I figured it would help to have a mentor to coach me through it. That turned out to be James Morrow, and he did so admirably. Roads is a masterful work of slipstream literary fantasy that follows the lives of women scattered through time, bound together by the salt uniting all black life. It was nominated for a Nebula and won the Gaylactic Spectrum Award. Hopkinson also edited anthologies centering around different cultures and perspectives, including Whispers from the Cotton Tree Root: Caribbean Fabulist Fiction (2000), Mojo: Conjure Stories (2003), and So Long, Been Dreaming: Postcolonial Science Fiction & Fantasy (2004). She also came out with the award-winning novelThe New Moons Arms in 2007, in which a peri-menopausal woman in a fictional Caribbean town is confronted by her past and the changes she must make to keep her family in her life.

While the stem cell ban hamstrung hESC work, Gurdons research facilitated yet another scientific breakthrough. Researchers began untangling how gene expression changed as stem cells differentiated, and in 2006, Shinya Yamanaka of Kyoto University reported the successful creation of mouse stem cells from differentiated cells. Using a list of 24 pluripotency-associated genes, Yamanaka systematically tested different gene combinations on terminally differentiated cells. He found four genesthereafter known as Yamanaka factorsthat could turn them into induced-pluripotent stem cells (iPSCs), and he and Gurdon would share a 2012 Nobel prize. In 2009, President Obama lifted restrictions on hESC research, and the first clinical trial involving products made using stem cells happened that year. The first human trials using hESCs to treat spinal injuries happened in 2014, and the first iPSC clinical trials for blindness began this past December.

Hopkinson, too, encountered complications and delays at points in her career. For years, Hopkinson suffered escalating symptoms from fibromyalgia, a chronic disease that runs in her family, which interfered with her writing, causing Hopkinson and her partner to struggle with poverty and homelessness. But in 2011, Hopkinson applied to become a professor of Creative Writing at the University of California, Riverside. It seemed in many ways tailor-made for me, Hopkinson said. They specifically wanted a science fiction writer (unheard of in North American Creative Writing departments); they wanted someone with expertise working with a diverse range of people; they were willing to hire someone without a PhD, if their publications were sufficient; they were offering the security of tenure. She got the job, and thanks to a steady paycheck and the benefits of the mild California climate, she got back to writing. Her YA novel, The Chaos (2012), coming-of-age novelSister Mine (2013), and another short story collection, Falling in Love with Hominids (2015) soon followed. Her recent work includes House of Whispers (2018-present), a series in DC Comics Sandman Universe, the final collected volume of which is due out this June. Hopkinson also received an honorary doctorate in 2016 from Anglia Ruskin University in the U.K., and was Guest of Honor at 2017 Worldcon, a year in which women and people of color dominated the historically white, male ballot.

While the Yamanaka factors meant that iPSCs became a standard lab technique, iPSCs are not identical to hESCs. Fascinatingly, two of these factors act together to maintain the silencing of large swaths of DNA. Back in the 1980s, researchers discovered that some regions of DNA are modified by small methyl groups, which can be passed down through cell division. Different cell types have different DNA methylation patterns, and their distribution is far from random; they accumulate in the promoter regions just upstream of genes where their on/off switches are, and the greater the number of methyl groups, the lesser the genes expression. Furthermore, epigenetic modifications, like methylation, can be laid down by our environments (via diet, or stress) which can also be passed down through generations. Even some diseases, like fibromyalgia, have recently been implicated as such an epigenetic disease. Turns out that the long-standing biological paradigm that rejected Lamarck also missed the bigger picture: Nature is, in fact, intimately informed by nurture and environment.

In the past 150 years, we have seen ideas of community grow and expand as the world became more connected, so that they now encompass the globe. The histories of science fiction and biology are full of stories of pioneers opening new doorsbe they doors of greater representation or greater understanding, or bothand others following. If evolution has taught us anything, its that nature abhors a monoculture, and the universe tends towards diversification; healthy communities are ones which understand that we are not apart from the world, but of it, and that diversity of types, be they cells or perspectives, is a strength.

World Blood Cancer Day 2020: Bring down your risk of this condition with easy diet tips – TheHealthSite

By daniellenierenberg

Bloodcanceris one of the most common types of cancer that generally affects people of all age groups. According to a report published by WHOs International Agency for Research on Cancer, India has the third-highest number of haematologicalcancers,popularly known as blood cancer. There was a time when cancer was considered an incurable disease, but over the recent years, the situations have changed drastically with the evolution in medical technology. This has made cancer treatments possible with up to 90 per cent survival chances. The World Blood Cancer Day is observed every year on May 28th around the world to show support for blood cancer patients. According to experts, early diagnosis in cancer, especially blood cancer, increases the chance of survival, thanks to evolved treatment modalities of the modern times. Also Read - World Blood Cancer Day 2020: Understanding the types and symptoms

Mostly, heamatological cancers originate in bone marrow, where blood is produced. This condition occurs when faulty blood cells affect the function of the normal ones that fend off infections and generate new cells. There are three types of blood cancers leukaemia, lymphoma and myeloma. In leukaemia, your body develops too many abnormal white blood cells (leukocytes) and makes it tough for your bone marrow to produce red blood cells. Lymphoma occurs when in the lymphocites while myeloma has its origin in the plasma cells of the blood. These are white blood cells produced in your bone marrow. Also Read - Researchers discover role of mutation in blood cancers

The prominent symptoms of blood cancer include chills, fatigue and weakness, night sweats, pain in the bones and joints, and swollen lymph nodes. It takes a toll on your immunity, making you susceptible to various infections and other conditions. Cancer also affects the rate at which your blood clots. So, small cuts or injuries may tend to bleed for a longer period of time. You may also experience unusual bruising, bleeding of the gums, and blood in stool. Women may go through heavy bleeding during their periods. Also Read - Today health tips: 6 lifestyle modifications to bring down your breast cancer risk

Experts are of the opinion that lymphoma in adults is 80-90 per cent curable and acute leukaemia in adults can be 40-50 per cent curable. However, many of the myeloma cases are incurable. The treatment for blood cancer mostly depends on the type of cancer, age of the patient and the severity of the cancer. On the basis of these factors, doctors may suggest chemotherapy, supportive care, stem cell transplantation, etc.

According to the guidelines of the American Oncology Institute, one can decrease the risk of blood can by following certain lifestyle measures. They include exercising regularly, eating healthy, avoiding exposure to herbicides, insecticides and radiations. Here are some simple dietary tips to bring down your chance of falling prey to this condition.

Eat generous amounts of vegetables and fruits, salads, beans and cereals in your diet. This will try increase your immunity.

These acids have anti-cancer properties. The best food sources could be fish, walnuts, soya bean, so on and so forth. You can also opt for fish oil supplements.

An antioxidant known as lycopene is present in tomatoes. It comes with cancer fighting properties. The best way to get lycopene from tomatoes is to heat them well. So, tomato soup can be a good option. You can also have it with other anti-oxidant rich veggies in the form of a salad.

Several studies have associated high intake of olive oil with cancer risk reduction. You can have this oil in your salads or sprinkle it on cooked veggies too. Also, try using olive oil while marinating your meat, fish or poultry.

Leonhardts Launchpads Announces Issuance of New U.S. Patent for Bioelectric Plus Biologics Platform for Organ Regeneration and Healing – Life Pulse…

By daniellenierenberg

United States, California, Irvine 05-27-2020 (PRDistribution.com) Latest Patent Further Strengthens Intellectual Property Portfolio Covering Novel Platform for Precisely ControllingRegenerative Protein Expressions Including Stem Cell Homing and Differentiation Control

Technology Has Key Potential Applications in Regeneration of Failing Heart, Brain, Kidney, Liver, Pancreas, Lungs, Aorta, Vision and Hearing as well as Transcutaneous Uses for Accelerated Wound Healing, Skin, Hair and Penile Function Regeneration (ED)Irvine, California, May 27th, 2020 Leonhardts Launchpads, an innovation and startup launch accelerator focused on developing novel therapeutics that harness the bodys innate mechanisms to regenerate failing organs and to heal tissues, today announced the issuance of a new U.S. patent providing broad protection for the companys first-of-its-kind combination bioelectrics and biologics technology platform, which has multiple potential therapeutic applications in organ regeneration and recovery. Previous stem cell therapies that delivered stem cells alone in a single application failed to regenerate organs fully. Electrical stimulation technologies to date have failed to zero in on and deliver the precise right bioelectric signaling sequences for controlling specific regenerative protein expressions when and where needed. This pioneering technology platform is the first to combine the powerful ability of bioelectric stimulation with repeat deliveries of not just stem cells but a whole host of support factors similar to an egg yolk designed to help cells survive, proliferate, engraft and differentiate with the intention of fully regenerating failing organs. stated primary inventor, Executive Chairman and CEO Howard J. Leonhardt.

In 1995 Howard Leonhardt filed his first patent for a stem cell and biologics delivery system for organ repair ProCell https://patents.google.com/patent/US5693029A/en based on work that began in 1988. In 1998 the Leonhardt team began collaboration with Dr. Doris Taylor whom that year published a landmark paper in Nature Medicine https://www.nature.com/articles/nm0898-929 on repair of infarcted hearts with myoblast cells. Dr. Taylor currently still serves as co-chair of our Scientific Advisory Board today. In 1999 the Leonhardt team worked with Dr. Shinichi Kanno to publish in Circulation, the Journal of the American Heart Association, pioneering results with bioelectric stimulation driven VEGF protein expression for limb salvage via angiogenesis in animals https://www.ahajournals.org/doi/abs/10.1161/01.cir.99.20.2682 and filed a patent application for the same within a year. Since then the Leonhardt team and LeonhardtsLaunchpads and itsportfolio of startupshas had issued, pending,optioned orlicensed over 600patentclaims for organregeneration andrecovery. In 2001 Howard Leonhardt and Dr. Juan Chachques filed patents on bioelectric stimulation controlled myogenesis and dynamic cardiac support with an early less potent stem cell homing signal. That same year a Leonhardt led team working with Dr. Patrick Serruys completed the landmark first ever case of non-surgical cell based regeneration of a damaged human heart in The Netherlands. Howard Leonhardt began a collaboration at that time with Dr. Jorge Genovese co-inventor of this patent, and BioLeonhardts VP of Bioelectric Regeneration Research, that continues to this day.

BREAKTHROUGH! Scientists Discover Particular Protein that Could Block Cancer Growth – Science Times

By daniellenierenberg

The Faculty of Health and Medical Sciences at the University of Copenhagen recently discovered how a particular protein, Phosphoprotein phosphatase 2A (PP2A), inhibits tumor development in mice.

Proteins are complex molecules in cells that are necessary for the function, structure, and regulation of the body's organs and tissues. Proteins have five primary functions: antibodies, enzymes, messengers, structural components, and transport or storage of atoms or small molecules.

Professor Jakob Nilsson, from the Novo Nordisk Foundation Center for Protein Research, explained that PP2A is called a household protein as it can be commonly found in most places. Everything that lives with simple cells or complex cells contain PP2A.

The PP2A Protein is also being studied by pharmaceutical companies as it is known to show unique patterns of kinase opposition, or simply, it is a tumor suppressor. Protein kinases are enzymes that induce change, switching active proteins into an inactive form.

While there is still insufficient research on which specific types of proteins PP2A regulates to prevent cancer, results from the new data do gain more insight.

Other tumor suppressor proteins include the retinoblastoma protein (pRb) and the p53 gene. Both regulate the cycling behavior of cells in a process called cell proliferation and growth are known as cell cycle progression.

Rb has a vital part in regulation G1/S transition, which is the 'start' checkpoint which controls the production of starter kinase proteins. What follows is Rb's 'role in the functioning of normal andcancer stem cells,' as well as its effect on the 'energy metabolism of cancer cells.'

According to a study called Nanostructures for Cancer Therapy, P53 is a protein that can 'respond to hypoxia, DNA damage, and loss of normal cell contacts when activated,' as it mediates the growth and death of cells.

The same study notes, 'targeting p53-MDM2 interaction would be attractive in cancer therapy.'

Associate Professor Marie Kveiborg from the Biotech Research and Innovation Centre notes that what is new about their study is that they can show how the specific PP2AB56 'selects the phosphate groups that shall be removed from other proteins,' while it turns off the enzyme ADAM17. ADAM17 being switched off resulted in 'inhibition of tumor growth in mice.'

A disintegrin and metalloprotease domain 17 (ADAM17) is a protein-coding gene associated with diseases including inflammatory skin (psoriasis), inflammatory bowel disease (Crohn's disease), and breast cancer. The test mice were all injected with three variations of ADAM17 cells.

On the day of injection, '4T1 A17wt, I762A, and LEE cells,' all ADAM17 variants, were given and the scientists monitored tumor growth through time.

When they began observing how PP2A-B56 interacted with ADAM17, 'none of the mice injected with ADAM17 LEE cells reached tumor endpoint criteria, as opposed to ADAM17 wt or I762A injected mice, which exhibited only 50% survival by the end of the experiment.'

The newly discovered data on cancer research will hopefully develop into studies with human tumors, expressed by the researchers. The scientists concluded, 'the B56 inhibitor displays excellent specificity toward the PP2AB56 holoenzyme family.' As a result, scientists also want to make additional research to determine if PP2A also can regulate other proteins with its tumor suppressor function.

A caveolin binding motif in Na/K-ATPase is required for stem cell differentiation and organogenesis in mammals and C. elegans – Science Advances

By daniellenierenberg

INTRODUCTION

Embryonic development is characterized by the temporal and spatial regulation of cell proliferation, migration, differentiation, and tissue formation. Although these processes are genetically determined, several signaling mechanisms including Wnt have been recognized as essential in regulating cell lineage specification and organogenesis (13).

The Na/Kadenosine triphosphatase (ATPase) (NKA), discovered in crab nerve fibers by Skou (4), belongs to the P-type ATPase superfamily. It has an enzymatic function that couples adenosine 5-triphosphate (ATP) hydrolysis to the transmembrane movement of Na+ and K+ in a cell lineagedependent manner. For example, while the NKA is involved in the formation of action potentials in excitable cells, its polarized distribution is key to the functionality of the epithelium.

In addition to its canonical enzymatic function, we and others have shown that the NKA has an enzymatic activityindependent signaling function through its interactions with membrane cholesterol and proteins such as Src, epidermal growth factor (EGF) receptor, and caveolin-1 (58). We use the term signaling with liberty here, referring to the ability of NKA to work as a receptor, a scaffold, and a signal integrator by regulating the functions of its interacting proteins. This newly appreciated signaling function of the NKA has been implicated in several cellular processes (912). However, direct genetic evidence supporting a role for NKA signaling in animal physiology and disease progression is still lacking. This is due, in part, to the technical difficulties in studying its signaling separately from its ATPase-mediated pumping function because the latter is required for the survival of animal cells (13). Fundamentally, it is unknown whether the signaling function is an intrinsic property of the protein NKA, as its Na+- and K+-driven enzymatic activity has been recognized as. Therefore, we were prompted to address two important questions: (i) Were the signaling and Na+/K+ transport functions of the NKA coevolved? (ii) If so, does the signaling function of NKA represent a primordial yet common mechanism for the regulation of a fundamental process in animal biology?

Structurally, the NKA is composed of both and subunits. The subunit contains the binding sites for Na+/K+ as well as ouabain, which are distinct from that of other P-type ATPases (14). It also has an N-terminal caveolin binding motif (CBM) proximal to the first transmembrane helix (fig. S1A). To assess the functionality of this motif, we made F97A and F100A mutations that map to the rat 1 NKA sequence. This strategy has been used by others to study the function of CBM in proteins other than the NKA (15). We used a knockdown and rescue protocol to generate a stable cell line (LW-mCBM) that essentially expresses just the CBM mutant 1, which was confirmed using [3H]ouabain binding assays (fig. S1B). Western blot and confocal imaging analyses showed that the expression of mutant 1 NKA in LW-mCBM was comparable to that in the control cell line, named AAC-19 cells (fig. S1, B and C). The expression of CBM mutant 1 was sufficient to restore the expression of the 1 subunit of the NKA, allowing normal plasma membrane targeting of the CBM mutant NKA in LW-mCBM cells (fig. S1, C and D). The successful generation of a stable CBM mutant 1 cell line suggests that the CBM is not essential for the enzymatic activity of the NKA because the ion-transporting function is necessary for animal cell survival (13). In further support, we conducted kinetic studies of the CBM mutant NKA. As shown in Fig. 1A, the overall enzymatic activity per unit of 1 NKA expression was identical between the control AAC-19 and LW-mCBM cells. The Km values of Na+, K+, and ouabain were comparable between the CBM mutant NKA and control (Fig. 1, B to D) (16). Together, these data indicate that the N-terminal CBM is not directly involved in the regulation of the enzymatic properties of the NKA.

(A) Crude membrane preparations were made from AAC-19 and LW-mCBM cells and measured for ouabain-sensitive ATPase activity as described in Material and Methods. (B) Ouabain concentration curve. Crude membrane from LW-mCBM cells was prepared and measured for ATPase activity in the presence of different concentrations of ouabain. Data are shown as percentage of control, and each point represents three independent experiments. Curve fit analysis and IC50 (median inhibitory concentration) were calculated by GraphPad. (C and D) Measurements of Na+ and K+ Km. Assays were done as in (B). The combined data were collected from at least three repeats, and Km value (means SEM) was calculated using GraphPad.

On the basis of the above, we next turned our attention to determining the effects of the CBM mutation on signaling capabilities of the 1 NKA. Specifically, we first conducted immunoprecipitation experiments. As we reported previously in many types of cells (8), immunoprecipitation of caveolin-1 coprecipitated 1 in AAC-19 cells. In contrast, mutation of the CBM resulted in an over 80% decrease in coprecipitated 1 in LW-mCBM cells (Fig. 2A).

(A) Cell lysates from AAC-19 and LW-mCBM were immunoprecipitated (IP) with polyclonal anticaveolin-1 antibody. Immunoprecipitated complex was analyzed by Western blot for 1 and caveolin-1 (n = 4). **P < 0.01 compared to AAC-19. (B) Cell lysates from AAC-19 and LW-mCBM cells were subjected to sucrose gradient fractionation as described in Materials and Methods. A representative Western blot of three independent experiments was shown. **P < 0.01 in comparison to AAC-19. (C) AAC-19 and LW-mCBM cells were treated with different concentrations of ouabain for 10 min and analyzed by Western blot. A representative Western blot was shown (n = 4). *P < 0.05 versus 0 mM ouabain. (D) Cell growth curves of AAC-19 and LW-mCBM. *P < 0.05 versus AAC-19 cells. (E) BrdU assay of AAC-19 and LW-mCBM. The values are means SEM from at least three independent experiments. Photo credit: Xiaoliang Wang, Marshall Institute for Interdisciplinary Research at Marshall University.

To substantiate these observations, we next conducted a detergent-free and carbonate-based density gradient fractionation procedure and found that 1 NKA and its main signaling partners (Src and caveolin-1) were co-enriched in the low-density caveolar fractions, as previously reported in epithelial cells (8, 17). In sharp contrast, the expression of the CBM mutant 1 caused the redistribution of these proteins from low-density to high-density fractions (Fig. 2B). Quantitatively, when the ratios of fraction 4/5 of each protein versus total were calculated, we found that the low-density fraction 4/5 prepared from the control AAC-19 cells contained ~60, ~70, and 80% of caveolin-1, Src, and 1 NKA, respectively. However, in LW-mCBM cells, only ~20% of caveolin-1, Src, and 1 NKA were detected in fraction 4/5 (Fig. 2B).

To address the functional consequences of the dissociation of the 1 NKA from its signaling partners in LW-mCBM cells, we exposed these cells to ouabain, a specific agonist of the receptor NKA/Src complex. As shown in Fig. 2C, while ouabain stimulated phosphorylation of extracellular signalregulated kinase (ERK), a downstream effector of the NKA/Src signaling pathway in AAC-19 cells (5, 8), it failed to do so in LW-mCBM cells.

We have previously shown that 1 NKA signaling is key to the dynamic regulation of cell growth (16, 18). As shown in Fig. 2D, LW-mCBM cells grew much slower than AAC-19 cells. 5-Bromo-2-deoxyuridine (BrdU) incorporation assays further verified that the expression of CBM mutant 1 resulted in an inhibition of cellular proliferation (Fig. 2E). In short, the above in vitro experiments indicate that the gain of CBM enables the NKA to perform the enzymatic activityindependent signaling functions.

With the preceding in vitro data suggesting that the CBM is critically important to the signaling function of the NKA, we next set forth to test the physiological significance of this finding. Thus, we generated a knock-in mouse line expressing the aforementioned CBM mutant 1. The CBM mutant (mCBM) mouse was generated using the Cre/LoxP gene targeting strategy (19), as depicted in fig. S2A. The chimeric offspring were crossed to C57BL6 females to yield mCBM heterozygous mice, and the desired F97A and F100A substitutions were verified (fig. S2B). mCBM heterozygous mice were born fertile and survived to adulthood. Our attempts to generate mCBM homozygous mice yielded no viable homozygous pups (Fig. 3A) in nearly 400 young mice genotyped by polymerase chain reaction (PCR). These results document for the first time that the CBM in the 1 subunit of the NKA represents a fundamental signaling mechanism essential for mouse embryonic development and survival.

There is evidence that endogenous ouabain is important in animal physiology because of its role in stimulating the signaling function of the NKA (10, 19, 20). Because the loss of the CBM abolishes ouabain-induced signal transduction in vitro, we tested whether administration of pNaKtide, a specific inhibitor of the receptor NKA/Src complex (21), would cause the same embryonic lethality as we observed in mCBM mice. As depicted in fig. S3, we observed no change in fetal survival after administration of pNaKtide to female mice before mating and continued until the end of pregnancy. It is important to mention that pNaKtide has been proven to be specific and effective in blocking the NKA/Src receptor signaling in vivo (2226), and our control experiments showed that pNaKtide could cross the placental barrier. Moreover, this lack of pNaKtide effect on mouse embryogenesis appears to be consistent with a previous report demonstrating that neutralization of endogenous ouabain by injection of an anti-ouabain antibody did affect the kidney development of neonatal mice but did not affect their overall survival (20). On the basis of these, we concluded that the NKA/Src receptor function in the CBM mutant embryo was not the direct cause of lethality and set out to identify a hitherto unrecognized NKA CBM-dependent yet NKA-Srcindependent underlying mechanism.

Embryo implantation within mice occurs around embryonic day 4.5 (E4.5) (27), followed by gastrulation around E5.5 to E7.5 (28), when the simple embryo develops into an organized and patterned structure with three germ layers (29). Subsequently, organogenesis takes place at E8.0 and onward; the patterned embryo starts to develop its organ systems including the brain, heart, limbs, and spinal cord.

To further analyze and explore the molecular mechanisms of the CBM mutation in the embryonic development of mice, we harvested the fertilized eggs at E1.5, and cultured them in vitro. It has previously been demonstrated that 1 knockout results in the failure of blastocyst formation (13). In contrast, we found that eggs from mCBM heterozygous parents developed into morphologically normal blastocysts. These findings indicate that loss of the CBM does not affect the molecular mechanisms necessary for blastocyst formation. Thus, a loss of functional 1 CBM and complete knockout of 1 NKA both result in embryonic lethality but differ by their specific mechanisms. Knockout of 1 NKA inevitably causes the loss of NKA enzymatic function, which is incompatible with life (13), and results in the failure of blastocyst formation in mice. In contrast, our in vitro data indicate that a loss of the CBM does not cause any notable alteration in NKA enzymatic activity, which is supported by the observation that mCBM mice are still capable of producing morphologically normal blastocysts. Consequently, CBM role in development appears to be critical at a developmental stage beyond blastocyst stage, and we further set out to identify this stage.

To this end, we collected and genotyped embryos or yolk sacs from mCBM heterozygous mice at different days of gestation. We first dissected 31 embryos at E12.5 from three different mice (Fig. 3A). Reabsorption and empty deciduae were observed in six implantation sites with only the mothers genotype detectable. At E9.5, we were able to dissect a total of 303 embryos. Sixty-four of them were mCBM homozygous (21%), 71 were wild-type (23%), and 168 were mCBM heterozygous (55%) (Fig. 3A).

To further analyze the embryonic developmental defects, we examined mCBM embryos at E7.5, E8.5, and E9.5. The embryos looked similar between wild-type and mCBM homozygous mice at E7.5 and E8.5 under dissection microscopy. However, we found several severe morphological defects in homozygous embryos at E9.5 (Fig. 3, C and D). First, the overall size of embryos was considerably reduced in mCBM homozygous embryos (about 35% the size of the wild-type embryos). In addition, the observed effect of the CBM mutant on embryonic size was gene dose dependent, as the mCBM heterozygous embryos were significantly smaller than those of wild-type embryos but much bigger than the homozygous embryos. Second, most homozygous embryos did not turn, a process normally initiated at E8.5, suggesting that the loss of a functional CBM was responsible for a developmental arrest at an early stage of organogenesis. Last, the most severe morphological defects were observed in the heads of the mCBM homozygous embryos. In addition to the reduced size (about 25% of the size of wild-type embryos), we observed that mCBM homozygous embryos failed to close their cephalic neural folds (anterior neuropore) as indicated by the arrow in Fig. 3B. This phenotype more closely resembled wild-type embryos at E8.0 to E8.5, suggesting again that the loss of CBM arrested organogenesis in its early stages. On the other hand, all heterozygous embryos, although smaller than wild-type embryos, showed normal head morphology (Fig. 3B).

To follow up on the above observations, we collected and made histological sections of wild-type, heterozygous, and homozygous embryos at E9.5 (Fig. 3, C and D). Normally, formation and closure of the anterior neuropore occurs at E9.5 (Fig. 3D). In sharp contrast, mCBM homozygous embryos developed defects in neural closure. Specifically, failure of neural tube closure at the level of forebrain, midbrain, and hindbrain was prominent in homozygous embryos (Fig. 3D).

To further explore the molecular mechanism by which the loss of the CBM led to defects in organogenesis, we next conducted RNA sequencing analyses (RNAseq) in wild-type and mCBM homozygous embryos. More than 17,000 genes were read out in either mCBM homozygous or wild-type samples. Data analyses indicated that 214 and 208 genes from mCBM homozygous embryos were significantly down- and up-regulated, respectively (fig. S4). Among them, the expression of a cluster of transcriptional factors important for neurogenesis was significantly reduced. As depicted in Fig. 4A, the expression of neurogenin 1 and 2 (Ngn1/2), two basic helix-loop-helix (bHLH) transcriptional factors (30), was significantly down-regulated in homozygous embryos. Ngn1/2 are considered to be determination factors for neurogenesis, while members of the NeuroD family of bHLH work downstream to promote neuronal differentiation (31). We found that the expression of NeuroD1/4 was further reduced in mCBM homozygous embryos. As expected from these findings, the marker of neural stem cells nestin (Nes) and other genes related to neurogenesis including huntington-associated protein 1 (Hap1), nuclear receptor subfamily 2 group E members 1 (Nr2e1), and adhesion G protein (heterotrimeric guanine nucleotidebinding protein)coupled receptor (Adgrb1) were all down-regulated in mCBM homozygous embryos (Fig. 4A). To verify these data, we performed reverse transcription quantitative PCR (RT-qPCR) analyses of both wild-type and mCBM homozygous embryos collected at E9.5. As depicted in Fig. 4 (B to D), the aforementioned transcriptional factors were all down-regulated in a cascade fashion. While a modest reduction was found with Ngn1/2, the expression of NeuroD1/4 was almost completely inhibited. To test whether the effects of the CBM mutation on the expression levels of these transcriptional factors were gene dose dependent, we also examined mRNA levels of Ngn1/2 and NeuroD1/4 in mCBM heterozygous embryos. As depicted in Fig. 4 (B and C), the expression of these genes followed the pattern found in homozygous embryos. The expression level in heterozygous embryos was significantly reduced compared to wild-type embryos but was much higher than that of mCBM homozygous embryos. These gene dosingdependent cascade effects suggest that the 1 NKA is an important upstream regulator but not a determinant of neurogenesis like Ngn1/2 (32) or a key receptor mechanism like Wnt is.

As a control, we also assessed the expression of different isoforms of NKA and caveolin-1. As depicted in fig. S5, no changes were detected in the expression of the 1 isoform of the NKA. This is expected, as the mutations were only expressed on exon 4. Previous reports have demonstrated that, in addition to the 1 isoform, neurons also express the 3 isoform, while muscle and glial cells express the 2 isoform of the NKA (9). No difference was observed in the expression of 3, while the expression of 2 was too low to be measured. We were also unable to detect any change in the expression of caveolin-1.

The total amount of protein recognized by the anti-NKA 1 antibody is unchanged in mCBM heterozygous mouse tissues compared to that of the wild type, albeit with changes in distribution in caveolar versus noncaveolar fractions. This indicates that the CBM mutant protein is fully expressed, as observed in cells (fig. S1), and further demonstrates that a reduction of enzymatic activity is not responsible for the observed phenotype in mCBM homozygous embryos. However, because the expression of wild-type 1 in mCBM heterozygous animals is most likely reduced, the phenotypic changes we observed in these mice could be due to the reduction of wild-type 1 expression rather than the expression of CBM mutant 1. To address this important issue, we collected embryos from 1 NKA heterozygous (1+/) mice and their littermate controls (33). In contrast to mCBM heterozygotes, reduction of 1 expression alone did not change the size of embryos (Fig. 3D), head morphology, or the expression of neuronal transcriptional factors (Fig. 4E). Because NKA 1 haploinsufficiency did not phenocopy mCBM heterozygosity, it was concluded that the mCBM allele was responsible for the observed changes.

The CBM in NKA has a consensus sequence of FCxxxFGGF (fig. S6). To assess the generality of CBM-mediated regulation, we first turned to the conserveness of the CBM in animal NKA. A database search reveals that, like Wnt, the mature form of NKA (i.e., containing CBM, Na+/K+ binding sites, and subunit) is absent in unicellular organisms but present in all multicellular organisms within animal kingdom (fig. S6). Further analysis of published data confirms the coevolutionary nature of the CBM and the binding sites for Na+ and K+ in the NKA. The first indication is from the analysis of single-cell organisms. No mature form of NKA is found in these organisms (fig. S6A). However, Salpingoeca rosetta, a marine eukaryote belonging to the Choanoflagellates class, undergoes a very primitive level of cell differentiation and specialization in their life cycle and expresses a putative NKA with several conserved motifs involved in the binding of Na+/K+. On the other hand, it contains no CBM (fig. S6) and there is also no evidence that it expresses a subunit.

Second, as depicted in figs. S6 and S7, Caenorhabditis elegans, an example of a metazoan organism, expresses a mature form of NKA (eat-6) that contains binding sites for Na+ and K+ as well as the N-terminal CBM. It also expresses a couple of putative NKA such as catp-2 (34). However, they contain neither the CBM nor Na+ and K+ binding sites.

Third, although the X amino acids in the NKA CBM in invertebrates vary, only conserved substitutions occurred in this motif. This is in sharp contrast to many other membrane receptors/transducers such as Patched and G that also contain a consensus CBM (figs. S6 and S7). Within vertebrates, the CBM sequence FCRQLFGGF in NKA remains completely conserved across all species. Moreover, this sequence remains conserved in all isoforms of the subunit except for the 4 isoform, which is exclusively expressed in sperm. The 4 isoform in some species still adapts the CBM sequence found in invertebrates (fig. S6). Moreover, of a total of nine subunits found in zebrafish (35), five appear to be 1 homologs that, like the 4 isoform, contain both vertebrate and invertebrate CBM sequences.

Last, turning to the evolutionary aspect of the receptor NKA/Src complex, we found that the Src-binding NaKtide and Y260 sequences, in sharp contrast to the CBM, are only conserved in mammalian ATP1A1 (fig. S7). Therefore, the NKA/Src receptor may have evolved after the acquisition of the CBM, and hence is not a part of the fundamental regulation of animal organogenesis (fig. S3).

In short, the N-terminal CBM, like the binding sites for Na+ and K+, is conserved in all subunits of NKA in animals, even after taking into consideration gene duplications and the generation of different isoforms or homologs. Thus, we postulate that this CBM must be evolutionally conserved to enable the NKA, in parallel with its enzymatic function, to serve an important role in the origination of multicellular organisms within the animal kingdom.

Organogenesis represents a unique feature of multicellular organisms. In considering the preceding findings, we reasoned that the loss of NKA CBM would also affect embryonic development in invertebrates such as C. elegans. To test our hypothesis, we used CRISPR-Cas9 to knock in the equivalent CBM double mutations of F75A and F78A in C. elegans NKA gene eat-6 (named as syb575) (fig. S8). Similar to the impact of the expression of CBM mutant 1 NKA in mice, no homozygous worms were produced, whereas the heterozygous worms hatched normally. Moreover, by using the gene balancer nT1, we confirmed that the F75A and F78A double mutations induced embryonic lethality in syb575 homozygotes secondary to L1 arrest (Fig. 5A). Furthermore, the observed larval arrest due to the loss of the eat-6 CBM was rescued by a transgene expressing a wild-type eat-6 complementary DNA (cDNA) through an extrachromosomal array (Fig. 5B). The lethality phenotype in syb575 mutants was different from those of the eat-6 mutants defective in enzymatic (transport) activity, because while the eat-6 mutants had growth defects, they were able to grow past the L1 stage (36). An exception to this was a cold-sensitive eat-6 (ad792) mutant with severely reduced transport activity, which exhibited L1 arrest at lower temperatures similarly to the syb575 mutant worms (36). Overall, those data suggest that both CBM-mediated signaling and ion transport activity by the NKA are essential to full-scale organogenesis in C. elegans.

In short, our data indicate that loss of the NKA CBM results in defective organogenesis in both mice and C. elegans. This, together with our finding that the NKA CBM is conserved in all NKA regardless of isoform or homolog, indicates that the NKA was originally evolved as a dual functional protein in multicellular organisms, and that it represents a primordial and common mechanism for regulating stem cell differentiation and early stage of organogenesis in animals.

Turning now to even more general features of the CBM in organogenesis, we searched for the plant plasma membrane H-ATPase that functions equivalently to the animal NKA. Like the NKA, the plant plasma membrane H-ATPase also contains a sequence motif at the first transmembrane segment that is in accordance with the consensus CBM. This motif is completely conserved from blue algae to land plants but does not exist within yeast and bacteria (fig. S6).

To assess the human relevance of our findings, we used CRISPR-Cas9 gene editing to generate the same mutations in human induced pluripotent stem cells (iPSCs) (fig. S9). As depicted in Fig. 5C, the expression of mutant CBM 1 reduced the colony formation ability of human iPSCs. Concomitantly, this was accompanied by a significant reduction in the expression of stemness markers (both Nanog and Oct4), and transcriptional factors controlling germ layer differentiation (gene MIXL and T for mesoderm, OTX2 and SOX1 for ectoderm, and GATA4 and SOX17 for endoderm) (Fig. 5D). These findings confirm an essential role of the NKA CBM in the regulation of stem cell differentiation and suggest the potential utility of targeting the NKA for improving tissue regeneration.

The canonical Wnt pathway is made of multiple components localized in the plasma membrane and cytosol (2, 3). Functionally, this pathway is critically important in animal organogenesis (2, 37). For example, it plays an essential role in the establishment of neurogenic niches and regulates the differentiation of neural stem cells into neuroblasts during organogenesis by regulating the expression of transcriptional factors Ngn and NeuroD (37, 38). Thus, we were prompted by the observed neural defects in mice to test whether the expression of the CBM mutant 1 NKA affects Wnt/-catenin signaling.

In the first set of studies, we examined the cellular distribution of -catenin in LW-mCBM cells. As depicted in Fig. 6A, confocal imaging analysis showed that -catenin was distributed away from the plasma membrane in a vesicle-like form in LW-mCBM cells. To verify this finding, we fractionated the cell lysates as performed in Fig. 3B and observed that -catenin, like Src and caveolin-1, moved from the low-density fractions to high-density fractions when compared to control cells (Fig. 6B). Control experiments showed no changes in the expression of E-cadherin, glycogen synthase kinase3 (GSK-3), LRP5/6 (Low-density lipoprotein receptor-related protein 5 and 6), and -catenin in LW-mCBM cells (Fig. 6C).

(F) Wnt3a induced TOPFlash luciferase report assay in AAC-19, LX-2, and LW-mCBM cells (n = 4). ***P < 0.01.

To test whether these changes in -catenin distribution alter the function of canonical Wnt signaling, we conducted a TOPFlash luciferase activity assay (39). Cells were transiently transfected with the reporter plasmid, exposed to Wnt3a conditional medium, and then subjected to TOPFlash luciferase assays. As shown in Fig. 6D, while Wnt3a induced a greater than 35-fold increase in luciferase activity in AAC-19 cells, it only produced a fourfold increase in LW-mCBM cells, which equates to an approximate 90% reduction in the dynamics of Wnt activation. To further test the impact of the CBM mutation on Wnt signaling, we examined the effects of Wnt3a on the expression of Wnt target genes. Cells were exposed to Wnt3a for 6 hours and subjected to RT-qPCR analysis. As depicted in Fig. 6E, while Wnt3a increased the expression of c-Myc, Lef, and NKD1 expression in AAC-19 cells, it failed to do so in LW-mCBM cells.

On the basis of the above observations, we reasoned that the NKA CBM might play an essential role in the dynamic regulation of Wnt signaling. We therefore analyzed Wnt signaling in our LX-2 cell line. This cell line was made by the same strategy used for the generation of LW-mCBM cells, and it expresses essentially just the 2 isoform (40). We have observed that 2 NKA, like CBM mutant 1, maintains cellular pumping capacity but is unable to signal via Src like a wild-type 1 NKA (40). However, unlike CBM mutant 1, 2 does contain the same CBM at the N terminus (fig. S6). As depicted in Fig. 6F, expression of the 2 isoform produced a rescue of Wnt signaling dynamics when compared to that in LW-mCBM cells, which reinforces the idea that the NKA CBM is key to the dynamics of Wnt signaling. Like in LW-mCBM cells, no change in -catenin expression was noted in LX-2 cells. However, compared to LW-mCBM cells, caveolin-1 expression was decreased in LX-2 cells, while ERK activity was increased (Fig. 6C). Together, these findings suggest that the conserved NKA CBM is essential for regulating Wnt signaling, which is independent of the pumping or CTS (ardiotonic steroid)activated Src-dependent signaling transduction.

To see whether there is evidence of Wnt signaling defects in mCBM homozygous embryos, we examined the RNAseq data using a tool kit of pathway analysis. As depicted in fig. S10, Wnt signaling appears to be defective at the transcriptional level. First, the expression of one of the Wnt receptors [Frizzled homolog 5 (Fzd5)] and one of the Wnt ligands (Wnt7b) was down-regulated (fig. S10A). Second, the Wnt/-catenin signaling inhibitor, secreted frizzled-related protein 5 (Sfrp5), was up-regulated in mCBM homozygous embryos. Third, the -catenin destruction complex component adenomatosis polyposis coli (APC) was down-regulated in mCBM homozygous embryos. All these defects in Wnt signaling were confirmed by RT-qPCR analysis of both wild-type and mCBM homozygous embryos at E9.5 (fig. S10B). In addition, APC down-regulation was also observed at the protein level in mCBM iPSCs (fig. S10C). Last, the defect in Wnt signaling was further substantiated by the altered expression of Wnt downstream target genes. As shown in fig. S10B, the expression of Lef and NKD1 was significantly reduced in mCBM homozygous embryos. The expression of c-Myc was too low to be detected.

Together, these data provide strong support to the notion that the CBM is a key to the regulation of Wnt by the NKA. We hypothesize that this critical function of the NKA CBM may explain why the CBM is conserved in all four subunit isoforms of the NKA. It is important to mention that the specific molecular defects in Wnt signaling that we have identified were tested in epithelial cells, a model we have previously used to characterize 1-specific signaling functions (16, 41). In view of the cell/tissue specificity of both NKA expression and subunit assemble (42) and Wnt signaling (13, 37), it is likely that this mechanism does not fully explain the Wnt signalingrelated defects in embryogenesis.

The enzymatic function of NKA coordinates the transmembrane movement of Na+/K+, which is essential for the survival of individual animal cells. At the tissue/organ level, the ATP-powered transport of Na+/K+ by the NKA is required for neuronal firing, muscle contraction, and the formation and functionality of epithelia and endothelia. The NKA was found to be essential for forming septate junction in Drosophila melanogaster (43, 44) via a regulatory mechanism independent of its ion-pumping activity. Here, we reveal an additional fundamentally important role of NKA in the regulation of signal transduction through a separate functional domain (CBM) unrelated to its enzymatic activity.

Our findings raise the question of why NKA acquired the CBM in addition to its binding sites for Na+ and K+. One possible explanation for this is that the additional functionality in NKA (fulfilled by the CBM) evolved for the purpose of regulating stem cell differentiation and organogenesis in multicellular organisms. Two observations support this hypothesis. First, both Wnt and NKA are present in the first multicellular organisms within the animal kingdom and are evolutionally conserved ever since. Thus, it is likely that the NKA and Wnt work in concert to enable stem cell differentiation and organogenesis in animals. Second, while Wnt is key to the cellular programs of stemness and cell lineage specification (2), it does not directly participate in cell lineagespecific activities of newly differentiated cells. Instead, this particular function might be fulfilled by the NKA. Conceivably, the NKA could have been evolved, as exemplified by the mitochondrial cytochrome c in ATP generation, to bring together two seemingly unrelated processes (i.e., Wnt signaling regulation via the CBM and ion transport through Na+ and K+ binding) into one signaling circuitry, which is critical to the dynamic regulation of transcriptional factors that are required for organogenesis in a temporally and spatially organized manner. Needless to say, this hypothesis remains to be tested. In addition, other important signaling pathways such as Notch and Sonic Hedgehog may also be regulated by NKA.

It is also of interest to note the evolutionary conserveness of the CBM in the plant plasma membrane H-ATPase. Like its counterpart within the animal kingdom, the plasma membrane H-ATPase is essential for plant organogenesis (45). Unlike the NKA, the plasma membrane H-ATPase exists in single-celled organisms such as yeast, and their ion-pumping function is regulated by similar mechanisms (46). However, yeast, with no use for cellular machinery needed for organogenesis, does not contain the H-ATPase with conserved CBM. Moreover, we also observed that no CBM exists in the plasma membrane Ca-ATPase (fig. S6), both of which belong to the same type II P-type ATPase family as the NKA. While the Ca-ATPase is a more ancient protein than the NKA, as its expression can be found in unicellular organisms, the H/K-ATPase appeared later than the NKA, at some point during the development of vertebrates. Thus, we suggest that the NKA may have evolved from a P-ATPase of unicellular organisms via the gain of both the CBM and Na+/K+ binding sites. In contrast, the H/K-ATPase may have evolved from the NKA, losing not only the Na+ binding site but also the CBM.

We have shown a direct interaction between the NKA and caveolin-1 (8, 17), which has been independently confirmed (47). The loss of the CBM significantly reduced the interaction between NKA and caveolin-1 as revealed by multiple assays. In addition to caveolin-1, we and others have reported several signal transductionrelated interactions (48). Of these, the potential interaction between 1 NKA and Src has attracted the most attention, especially in the past 10 years (7). While most studies indicated an important role of Src in CTS-activated signal transduction via 1 NKA, several publications have questioned whether 1 NKA interacts with Src directly to regulate Src functionality (49, 50). While this important difference remains to be experimentally addressed, we would like to point out the following facts. First, while we recognize the merit of using purified protein preparation to study protein interaction, it is important to recognize the limitation of using purified Src from bacterial expression system because they are heterogeneously phosphorylated. Second, we have reported multiple lines of evidence that support a direct interaction between 1 NKA and Src, including the identification of isoform-specific Src interaction, the mapping of potential Src-interacting sites in the 1 isoform, and the development of pNaKtide as Src inhibitor and receptor antagonist. These findings have substantially increased our understanding of 1 NKA/Src interaction in cell biology and animal physiology. It is important to mention that several groups not associated with us have successfully used pNaKtide to block ouabain and NKA signaling in vitro and in vivo (2326, 51). While our group and others continue to characterize the molecular basis and biological function of the NKA/Src receptor complex, we propound that the question of NKA/caveolin-1 interaction is a more pressing one in the context of this study. The role of CBM in caveolin-protein interaction and caveolae-related signaling is still debated (41, 52, 53).

Last, we conclude from these interesting findings that the NKA is not just an ion pump or a CBM-directed regulator but a critical multifunctional protein. This whole functionality underlies a hitherto unrecognized common mechanism essential for stem cell differentiation and organogenesis in multicellular organisms within the animal kingdom. Moreover, many recent studies also support the concept that the 1 NKA has acquired more functional motifs (e.g., Src-binding sites for the formation of NKA/Src receptor complex) during evolution. In addition, we have demonstrated that either knockdown of 1 NKA or the expression of an N-terminal fragment containing the CBM of the 1 subunit was sufficient to attenuate purinergic calcium signaling in renal epithelial cells (54). The 1 NKA is also found to be essential for CD36 and CD40 signaling in macrophages and renal epithelial cells (55, 56). Aside from the profound biological and fundamental implications, the previously unidentified NKA-mediated regulation of Wnt signaling through its N-terminal CBM may have substantial implications in our understanding of disease progression. The rapidly increasing appreciation of Wnt signaling in the pathogenesis of cancer and cardiovascular diseases (2, 3, 38) underlies the potential utility of NKA as a multidrug target (12, 22, 57, 58).

14-year-old girl is only chance to save dad’s life – Chinchilla News

By daniellenierenberg

IN A stark hospital room, Damian Cross waits for his 14-year-old daughter to save his life.

Shauna is less than 10km away at the Queensland Children's Hospital having her bone marrow extracted.

Despite only being a half match for her father, it was the best solution during a time when full match bone marrow was difficult to come by due to COVID-19 travel restrictions.

The family are a long way from their Coraki home where for a year Damian has been in remission from leukaemia after five rounds of chemotherapy.

"Leukaemia has come back and my only hope for cure now is my 14-year-old daughter," he said.

At Royal Brisbane Hospital with his partner Amy Rolfe by his side, the 33-year-old was under sedation for a bone marrow biopsy.

Shauna's bone marrow will be collected through a needle in her neck.

"Shauna has a fear of needles but hasn't batted an eye at the catheter in her neck," Amy said.

In preparation to receive his daughter's bone marrow, Damian will undergo three days of chemotherapy and four days of radiation to wipe out his cells.

"Then he gets her cells," Amy said.

Donor cells, especially when they are a half match, could attack Damian's cells.

"He'll be here for 100 days after the transplant," Amy said.

"Three to four weeks in hospital and then we have to stay in Brisbane for three months."

Damian will be on anti-rejection drugs and the procedure can fail within a three-year period.

The family is hopeful though and urge Australians to consider registering for bone marrow donation through the Australian Bone Marrow Donor Registry.

The World Marrow Donor Association operates a global database to find the best stem cell

source with a database of 36,214,535 donors from 98 different registries in 53 different countries.

Amy said Germany had the best bone marrow donor rate.

The WMDA said COVID-19 infection had the potential to impact and interfere with the timely provision of cells across international borders.

It is currently uncertain whether COVID-19 is transmissible parenterally, and it seems prudent to defer donors from countries with a high rate of COVID-19 infection, WMDA said.

Support the family through their crowdfunding campaign.

By daniellenierenberg

SOUTH SAN FRANCISCO--(BUSINESS WIRE)--Imago BioSciences, Inc. (Imago), a clinical stage biopharmaceutical company developing innovative treatments for myeloid diseases, today announced that positive Phase 2 data from its lead pipeline program bomedemstat (IMG-7289), will be presented at the Virtual Edition of the 25th EHA Annual Congress beginning June 12, 2020.

Title: A PHASE 2 STUDY OF BOMEDEMSTAT (IMG-7289), A LYSINE-SPECIFIC DEMETHYLASE-1 (LSD1) INHIBITOR, FOR THE TREATMENT OF LATER-STAGE MYELOFIBROSIS (MF)

Session Topic: 16. Myeloproliferative Neoplasms

Final Abstract Code: EP1080

The data demonstrates the potential of bomedemstat as a monotherapy in intermediate-2 and high-risk patients with myelofibrosis who have become intolerant of, or resistant to, or are ineligible for a Janus Kinase (JAK) inhibitor.

Imago is currently conducting a Phase 2 study of bomedemstat in five countries. Clinical endpoints include spleen volume reduction, reduction in total symptom scores, and improvement in circulating inflammatory cytokines, anemia, bone marrow fibrosis and blast count. For additional information, visit cliniciatrials.gov (NCT03136185).

About Bomedemstat (IMG-7289)

Bomedemstat is being evaluated in an open-label Phase 2 clinical trial for the treatment of advanced myelofibrosis (MF), a bone marrow cancer that interferes with the production of blood cells. The endpoints include spleen volume reduction and symptom improvement at 12 and 24 weeks of treatment. Bomedemstat is used as monotherapy in patients who are resistant to, intolerant of, or ineligible for a Janus Kinase (JAK) inhibitor.

Bomedemstat is a small molecule developed by Imago BioSciences that inhibits lysine-specific demethylase 1 (LSD1 or KDM1A), an enzyme shown to be vital in cancer stem/progenitor cells, particularly neoplastic bone marrow cells. In non-clinical studies, IMG-7289 demonstrated robust in vivo anti-tumor efficacy across a range of myeloid malignancies as a single agent and in combination with other chemotherapeutic agents. Bomedemstat (IMG-7289) is an investigational agent currently being evaluated in ongoing clinical trials (ClinicalTrials.gov Identifier: NCT03136185 and NCT02842827). Bomedemstat has FDA Orphan Drug and Fast Track Designation for the treatment of myelofibrosis and essential thrombocythemia, and Orphan Drug Designation for treatment of acute myeloid leukemia.
