LA JOLLA, CA—The Salk Institute has been awarded a $2.3 million grant by the California Institute for Regenerative Medicine (CIRM) for translational research focusing on developing a novel stem cell based therapy for Parkinson’s disease.
LA JOLLA, CA—Reprogramming adult cells to recapture their youthful “can-do-it-all” attitude appears to leave an indelible mark, found researchers at the Salk Institute for Biological Studies. When the team, led by Joseph Ecker, PhD., a professor in the Genomic Analysis Laboratory, scoured the epigenomes of so-called induced pluripotent stem cells base by base, they found a consistent pattern of reprogramming errors.
LA JOLLA, CA—In analyzing the molecular sensor for the plant growth hormone brassinolide, researchers at the Salk Institute for Biological Studies discovered that although plants took an evolutionary path different from their animal cousins, they arrived at similar solutions to a common problem: How to reliably receive and process incoming signals.
LA JOLLA, CA—Among stem cell biologists there are few better-known proteins than nestin, whose very presence in an immature cell identifies it as a “stem cell,” such as a neural stem cell. As helpful as this is to researchers, until now no one knew which purpose nestin serves in a cell.
LA JOLLA, CA—Glioblastoma, the most common and lethal form of brain cancer and the disease that killed Massachusetts Senator Ted Kennedy, resists nearly all treatment efforts, even when attacked simultaneously on several fronts. One explanation can be found in the tumor cells’ unexpected flexibility, discovered researchers at the Salk Institute for Biological Studies.
LA JOLLA, CA—Mutant presenilin is infamous for its role in the most aggressive form of Alzheimer’s disease-early-onset familial Alzheimer’s-which can strike people as early as their 30s. In their latest study, researchers at the Salk Institute uncovered presenilin’s productive side: It helps embryonic motor neurons navigate the maze of chemical cues that pull, push and hem them in on their way to their proper targets. Without it, budding motor neurons misread their guidance signals and get stuck in the spinal cord.
LA JOLLA, CA—Salk researcher Edward M. Callaway, a professor in the Systems Neurobiology Laboratories has been awarded the distinction of AAAS Fellow for his “distinguished research on the organization and function of neocortical circuits.”
LA JOLLA, CA—In making your pro-longevity resolutions, like drinking more red wine and maintaining a vibrant social network, here’s one you likely forgot: dialing down your mitochondria. It turns out that slowing the engines of these tiny cellular factories could extend your life-an observation relevant not only to aging research but to our understanding of how cells communicate with each another.
LA JOLLA, CA—A collaborative paper by John A.T. Young, Ph.D., Nomis Foundation professor at the Salk Institute for Biological Studies and Sumit Chanda, Ph.D., associate professor at Sanford-Burnham Institute, has been identified by Science Watch® as the most-cited paper in the category of Molecular Biology & Genetics and is currently featured as a Fast-Moving Front paper on their website.
LA JOLLA, CA—Researchers at the Salk Institute for Biological Studies have discovered how AMPK, a metabolic master switch that springs into gear when cells run low on energy, revs up a cellular recycling program to free up essential molecular building blocks in times of need.
LA JOLLA, CA—In addition to fast food, desk jobs, and inertia, there is one more thing to blame for unwanted pounds-our genome, which has apparently not caught up with the fact that we no longer live in the Stone Age.
LA JOLLA, CA—A synthetic derivative of the curry spice turmeric, made by scientists at the Salk Institute for Biological Studies, dramatically improves the behavioral and molecular deficits seen in animal models of ischemic stroke and traumatic brain injury (TBI). Two new studies suggest that the novel compound may have clinical promise for these conditions, which currently lack good therapies.
LA JOLLA, CA—A close collaboration between researchers at the Salk Institute for Biological Studies and the Institute for Advanced Study found that the tumor suppressor p53, long thought of as the “Guardian of the Genome,” may do more than thwart cancer-causing mutations. It may also prevent established cancer cells from sliding toward a more aggressive, stem-like state by serving as a “Guardian against Genome Reprogramming.”
LA JOLLA, CA—Better known as the light sensor that sets the body’s biological clock, melanopsin also plays an important role in vision: Via its messengers-so-called melanopsin-expressing retinal ganglion cells, or mRGCs-it forwards information about the brightness of incoming light directly to conventional visual centers in the brain, reports an international collaboration of scientists in this week’s issue of PLoS Biology.
LA JOLLA, CA—The Board of Trustees of the Salk Institute for Biological Studies unanimously voted to elect Dr. Benjamin H. Lewis and Ms. Faye H. Russell as new members during its November 19 meeting in La Jolla.
LA JOLLA, CA—The Salk Institute for Biological Studies today announced the establishment of the Renato Dulbecco Chair in Genomics and the Roger Guillemin Chair in Neuroscience based on an endowment of $6 million from Irwin Jacobs, chairman of the Salk’s Board of Trustees, and his wife Joan Klein Jacobs.
LA JOLLA, CA–With few exceptions, jumping genes-restless bits of DNA that can move freely about the genome-are forced to stay put. In patients with Rett syndrome, however, a mutation in the MeCP2 gene mobilizes so-called L1 retrotransposons in brain cells, reshuffling their genomes and possibly contributing to the symptoms of the disease when they find their way into active genes, report researchers at the Salk Institute for Biological Studies.
LA JOLLA, CA–Fisetin, a naturally occurring compound found in strawberries and other fruits and vegetables, slows the onset of motor problems and delays death in three models of Huntington’s disease, according to researchers at the Salk Institute for Biological Studies. The study, published in the online edition of Human Molecular Genetics, sets the stage for further investigations into fisetin’s neuroprotective properties in Huntington’s and other neurodegenerative conditions.
LA JOLLA, CA—A collaborative effort between researchers at the Salk Institute for Biological Studies and the University of California, San Diego, successfully used human induced pluripotent stem (iPS) cells derived from patients with Rett syndrome to replicate autism in the lab and study the molecular pathogenesis of the disease.
LA JOLLA, CA–A study by researchers at the Salk Institute for Biological Studies revealed that stem cells can sense a decrease in available nutrients and respond by retaining only a small pool of active stem cells for tissue maintenance. When, or if, favorable conditions return, stem cell numbers multiply to accommodate increased demands on the tissue.
