Finding has implications for treatment of wide range of diseases Johns Hopkins scientists investigating chemical modifications across the genomes of adult mice have discovered that DNA modifications in non-dividing brain cells, thought to be inherently stable, instead underwent large-scale dynamic changes as a result of stimulated brain activity. Their report, in the October issue of Nature Neuroscience, has major implications for treating psychiatric diseases, neurodegenerative disorders,...

Scientists at Cold Spring Harbor Laboratory (CSHL) and the University of Southern California (USC) have uncovered intriguing new evidence helping to explain one of the ways in which a stem cell's fate can be determined. The new data show how the "marking" of DNA sequences by groups of methyl molecules — a process called methylation — can influence the type of cell a stem cell will become. The cellular maturation process, called differentiation, has long been thought to be...

  Salk scientists discover 'hidden' code in DNA evolves more rapidly than genetic code A "hidden" code linked to the DNA of plants allows them to develop and pass down new biological traits far more rapidly than previously thought, according to the findings of a groundbreaking study by researchers at the Salk Institute for Biological Studies. The study, published Sept. 16 in the journal Science, provides the first evidence that an organism's "epigenetic" code - an extra layer of...

Mariusz A. Wasik, MD, professor of Pathology and Laboratory Medicine, and Qian Zhang, MD, PhD, research assistant professor, both from the Perelman School of Medicine at the University of Pennsylvania, and their colleagues, found that a cancer-causing fusion protein works by silencing the tumor suppressor gene IL-2R common gamma-chain (IL-2RÃŽ³). The results, which appeared in a recent Proceedings of the National Academy of Sciences, suggest news targets for lymphoma and...

IVF research led by New Hampshire Reproductive Center fertility doctor, Kristen P Wright, MD, indicates IVF process effects DNA methylation associated with two syndromes (PRWEB) July 22, 2011 Since the birth of the first IVF baby in 1978, more than 3 million children have been born worldwide following IVF treatments. Numerous studies have been conducted to assess the overall health of children born after IVF. The majority of these studies on the safety of IVF have been reassuring....

For decades, scientists have known that DNA consists of four basic units -- adenine, guanine, thymine and cytosine. Those four bases have been taught in science textbooks and have formed the basis of the growing knowledge regarding how genes code for life. Yet in recent history, scientists have expanded that list from four to six. Now, with a finding published online in the July 21, 2011, issue of the journal Science, researchers from the UNC School of Medicine have discovered the seventh and...

Hallmark of cancer cells Scientists from the Hebrew University have identified the molecular basis for DNA breakage, a hallmark of cancer cells. The findings of this research have just been published in the journal Molecular Cell. The DNA encodes the entire genetic information required for building the proteins of the cell. Hence, DNA breaks disrupt the proteins and lead to changes in the cell function. These changes can lead to defects in the control of cellular proliferation resulting in...

Results suggest novel approach to developing targeted cancer therapies Scientists at Fox Chase Cancer Center have discovered a new mechanism used by cells in the body to turn on silenced genes. This process is critical in preventing the development of cancer"”suggesting the possibility of new therapies that might target the specific changes underlying the disease. The findings will be published online in the journal Cell on June 30, 2011. The process investigated by Alfonso Bellacosa,...

GREEN BAY, Wis., June 23, 2011 /PRNewswire/ -- Dr. Ajay Goel, Ph.D., Director of Epigenetics and Cancer Prevention at the Gastrointestinal Research Center at Baylor University Medical Center in Dallas, TX, has announced plans for a series of upcoming studies to continue to unlock the mechanisms by which curcumin prevents cancer via its influence on epigenetic activity. While many people believe there is a strong genetic influence in the development of cancer, Dr. Goel states this is...
