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.
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.
When sperm meets egg, the chemical instructions that tag sperm cells must be erased so that human life can start anew.
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.
