Discovery Links Shift in Metabolism to Stem Cell Renewal

Posted: Published on December 10th, 2014

Contact Information Available for logged-in reporters only Newswise Stem cells in early embryos have unlimited potential; they can become any type of cell, and researchers hope to one day harness this rejuvenating power to heal disease and injury. To do so, they must, among other things, figure out how to reliably arrest stem cells in a Peter Pan-like state of indefinite youth and potential. Its clear the right environment can help accomplish this, acting as a sort of Neverland for stem cells. Only now are scientists beginning to understand how. New collaborative research between scientists at Rockefeller University and Memorial Sloan Kettering Cancer Center offers an explanation: Stem cells can rewire their metabolism to enhance an erasure mechanism that helps them avoid committing to a specific fate; in turn, this improves stem cells ability to renew themselves. Experiments described today (December 10) in Nature link metabolism, chemical reactions that turn food into energy and cellular building materials, with changes to how genes are packaged, and, as a result, read. It turns out that by skewing their metabolism to favor a particular product, stem cells can keep their entire genome accessible and so maintain their ability to differentiate into any adult … Continue reading

Brain inflammation a hallmark of autism, large-scale analysis shows

Posted: Published on December 10th, 2014

PUBLIC RELEASE DATE: 10-Dec-2014 Contact: Shawna Williams shawna@jhmi.edu 410-955-8236 Johns Hopkins Medicine @HopkinsMedicine While many different combinations of genetic traits can cause autism, brains affected by autism share a pattern of ramped-up immune responses, an analysis of data from autopsied human brains reveals. The study, a collaborative effort between Johns Hopkins and the University of Alabama at Birmingham, included data from 72 autism and control brains. It will be published online Dec. 10 in the journal Nature Communications. "There are many different ways of getting autism, but we found that they all have the same downstream effect," says Dan Arking, Ph.D. , an associate professor in the McKusick-Nathans Institute for Genetic Medicine at the Johns Hopkins University School of Medicine. "What we don't know is whether this immune response is making things better in the short term and worse in the long term." The causes of autism, also known as autistic spectrum disorder, remain largely unknown and are a frequent research topic for geneticists and neuroscientists. But Arking had noticed that for autism, studies of whether and how much genes were being used -- known as gene expression -- had thus far involved too little data to draw many useful … Continue reading

Google Opens Its Cloud to Crack the Genetic Code of Autism

Posted: Published on December 10th, 2014

Google has spent the past decade-and-a-half perfecting the science of recognizing patterns in the chaos of information on the web. Now its applying that expertise to searching for clues to the genetic causes of autism in the vast sea of data contained in the human genome. On Tuesday, autism advocacy group Autism Speaks said it was partnering with Google to sequence the genomes of 10,000 people on the autism spectrum along with their family members. Google will host and index the data for qualified researchers to sift as they hunt for variations in DNA that could hint at autisms genetic origins. We believe that the clues to understanding autism lie in that genome, Rob Ring, Autism Speaks chief science officer, told WIRED. Wed like to leverage the same kind of technology and approach to searching the internet every day to search into the genome for these missing answers. The project will make use of Google Genomics, a tool launched by the company several months ago with little fanfare on Googles Cloud Platform. As sequencing the human genome becomes ever-faster and cheaperRing says it can be done for about $2,500, compared to nearly $3 billion for the Human Genome Projectthe volume … Continue reading

Researchers identify stem cells that can be reprogrammed

Posted: Published on December 10th, 2014

Major study: Professor Thomas Preiss from ANU JCSMR who has been involved in an international project researching stem cells. Photo: Graham Tidy Scientists, including some from Canberra, have identified a new type of stem cell which is easier to grow and manipulate as part of a major study detailing the changes cells undergo as they reprogram into stem cells. Experts from across the globe, including some from the Australian National University John Curtin School of Medical Research, have carried out the most detailed study of how specialised body cells can be reprogrammed to be like cells from the early embryo. "The ultimate goal with this work is to develop therapies in regenerative medicine which is a therapeutic approach whereby you would ultimately replace cells or tissues or organs that are failing in a patient with replacement parts that are made in a laboratory from the patient's own cells or from genetically highly similar stem cells," Professor Thomas Preiss from ANU's JCSMR said. Professor Preiss said it was hoped the research could help speed up the development of treatments for many illnesses and conditions.

Some NFL players use unproven stem cell therapies

Posted: Published on December 10th, 2014

MONDAY, Dec. 8, 2014 (HealthDay News) -- Some professional football players are seeking unproven stem cell therapies to speed their recovery from injuries. But experts are concerned that they may be unaware of the potential risks, a new report shows. Stem cell therapy has attracted the attention of elite athletes. A number of National Football League (NFL) players have highlighted their use of those therapies and their successful recoveries. Twelve NFL players are known to have received unapproved stem cell treatments since 2009. "The online data on NFL players and the clinics where they obtained treatment suggest that players may be unaware of the risks they are taking," report co-author Kirstin Matthews, a fellow in science and technology policy at Rice University's Baker Institute for Public Policy, said in a university news release. "Players who are official spokespersons for these clinics could influence others to view the therapies as safe and effective despite the lack of scientific research to support these claims," she added. Most of the players receive treatment in the United States, but several have gone to other countries for stem cell therapies that aren't available in the United States. "With the rise of new and unproven stem … Continue reading

Stem Cells Show Promise in Reducing Hardening of the Arteries

Posted: Published on December 10th, 2014

Durham, NC (PRWEB) December 10, 2014 The medical world is excited about the potential that stem cells have demonstrated in aiding the recovery of patients who have suffered a heart attack. Now, a new study appearing in the January issue of STEM CELLS Translational Medicine indicates that stem cells may also benefit those who suffer from hardening of the arteries. Hardening of the arteries or atherosclerosis occurs due to a buildup of fats, cholesterol and other substances in and on the artery walls. The arteries become hardened by fibrous tissue and calcification and, as the plaque grows, it clogs the artery tubes, reducing the oxygen and blood supply to the affected organ. If the artery becomes severely blocked, it can cause death of the tissue fed by the artery and lead to a heart attack or stroke. Based on the success of mesenchymal stem cells (MSCs) in treating a heart attack, Shih-Chieh Hung, M.D, Ph.D., of the Department of Medical Research, Taipei Veterans General Hospital, Taiwan, led a team of researchers who wanted to learn if MSCs transplanted in a patient in the early stage of atherosclerosis might prevent the diseases development and/or progression. MSCs are stem cells that can … Continue reading

Azaan Javaid: New Delhi, Dec 10, 2014, DHNS: In the year 1999, Renuka Bhagat, graduating from Jalandhar College, was preparing for her examinations when for the first time in her life faced difficulties while reading. Days later, her doctors words devastated her when medical examinations revealed that she was suffering from Retinitis pigmentosa (RP) a genetic condition that causes severe vision impairment and often blindness. Over the next few years, Bhagat would lose her eyesight and enter a state of depression lasting for years together. I was in my second year of college. I was pursuing my graduation in advertisement and sales promotion and suddenly the world turned upside down for me when I lost my vision and was not able to read any text. The confidence in me was shattered as I moved from a person with ability to a person with disability, Bhagat said barely holding back her tears. Bhagat mentioned about her plans of doing her Masters in Mass Communication. She managed to complete her graduation but found it extremely difficult to get into a decent college with provision for the differently abled. I was not getting the subjects which I wanted to study, said Bhagat. Ask … Continue reading

Posted: Published on December 9th, 2014

THOUSAND OAKS, Calif., Dec. 8, 2014 /PRNewswire/ --Amgen (NASDAQ: AMGN) today announcedthat new data from a pivotal Phase 2 study evaluating BLINCYTO (blinatumomab) for the treatment of adult patients with relapsed/refractory B-cell precursor acute lymphoblastic leukemia (ALL) was presented at the 56thAmerican Society of Hematology (ASH) Annual Meeting and Exposition. In one analysis from the '211 study, 40 percent of patients treated with BLINCYTO who achieved a complete remission (CR) or complete remission with partial hematologic recovery (CRh) were enabled to proceed to allogeneic hematopoietic stem cell transplant (HSCT). Additionally, a secondary analysis from the study found that 82 percent of patients who had a CR or CRh also had a minimal residual disease (MRD) response, a measure used to predict disease recurrence in patients with ALL. "The data from the '211 study expand the evidence of Amgen's BiTE immunotherapy as an advance in the management of this difficult-to-treat cancer, and importantly, served as the basis for the recent U.S. Food and Drug Administration (FDA) approval of BLINCYTO," said Sean E. Harper, M.D., executive vice president of Research and Development at Amgen. "In this study, BLINCYTO helped patients bridge to a stem cell transplant after achieving a remission, a key … Continue reading
