Latest Methylation Stories
Salk scientists discover 'hidden' code in DNA evolves more rapidly than genetic code.
Chromatin - the intertwined histone proteins and DNA that make up chromosomes – constantly receives messages that pour in from a cell’s intricate signaling networks: Turn that gene on. Stifle that one.
Medical researchers have discovered a new type of mechanism causing cancer susceptibility, showing that tiny changes in some anti-cancer genes can act as magnets to attract modifying â€œbiochemical tagsâ€, effectively switching them off and predisposing families to an increased risk of the disease.
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-2RÎ³).
A new study supports the use of a DNA-based "biomarker" blood test as a complement to the prostate-specific antigen (PSA) test currently offered to screen men for prostate cancer.
For decades, scientists have known that DNA consists of four basic units -- adenine, guanine, thymine and cytosine.
Mixed lineage leukemias rely on epigenetic changes to grow and survive; new molecule shows promise for targeting these changes therapeutically BOSTON, July 11, 2011 /PRNewswire-USNewswire/ -- A difficult-to-treat form of childhood leukemia relies on changes in the structure of DNA - so-called epigenetic changes - to wreak genomic havoc within white blood cells, according to one of two studies conducted by a research team at Children's Hospital Boston and Dana-Farber Cancer Institute.
Scientists at Fox Chase Cancer Center have discovered a new mechanism used by cells in the body to turn on silenced genes.
Using the latest gene sequencing tools to examine so-called epigenetic influences on the DNA makeup of colon cancer, a Johns Hopkins team says its results suggest cancer treatment might eventually be more tolerable and successful if therapies could focus on helping cancer cells get back to normal in addition to strategies for killing them.
