Acute Stress Alters Control of Gene Activity: Researchers Examine DNA Methylation
August 15, 2012 — Acute stress alters the methylation of the DNA and thus the activity of certain ... > full story -
What 10,000 Fruit Flies Have to Tell Us About Differences Between the Sexes
July 19, 2012 — What do you get when you dissect 10,000 fruit fly larvae? Scientists have discovered a way in which cells can adjust the activity of many different genes at once. Their findings overturn commonly ... > full story -
Discovery of 'Hopping' of Bacterial Enzyme Gives Insight Into Gene Expression
July 18, 2012 — Researchers' discovery of a variation of an enzyme's ability to "hop" as it moves along DNA, modifying the genetic material of a bacteria -- and its physical capability and behavior -- holds much ... > full story -
Mechanisms That Allow Embryonic Stem Cells to Become Any Cell in the Human Body Identified
July 18, 2012 — New research sheds light on pluripotency -- the ability of embryonic stem cells to renew themselves indefinitely and to differentiate into all types of mature cells. If scientists can replicate the ... > full story -
Differences Between Human Twins at Birth Highlight Importance of Intrauterine Environment
July 15, 2012 — Your genes determine much about you, but environment can have a strong influence on your genes even before birth, with consequences that can last a lifetime. Scientists have for the first time shown ... > full story -
Epigenetic Cause of Osteoarthritis Identified
July 6, 2012 — In breakthrough research, scientists discovered that osteoarthritis sufferers have a signature epigenetic change responsible for switching on and off a gene that produces a destructive enzyme. MMP13 ... > full story -
Rewiring DNA Circuitry Could Help Treat Asthma
July 5, 2012 — Reprogramming asthma-promoting immune cells in mice diminishes airway damage and inflammation, and could potentially lead to new treatments for people with asthma, researchers have found. The ... > full story -
Epigenetics Alters Genes in Rheumatoid Arthritis
July 3, 2012 — Researchers have investigated a mechanism usually implicated in cancer and in fetal development, called DNA methylation, in the progression of rheumatoid arthritis. They found that epigenetic changes ... > full story -
Molecular Clues to Link Between Childhood Maltreatment and Later Suicide
July 3, 2012 — Exposure to childhood maltreatment increases the risk for most psychiatric disorders as well as many negative consequences of these conditions. A new study provides important insight into one of the ... > full story -
New Role for RNAi Discovered: Epigenetic Memory May Pass RNA Silencing from One Generation to the Next
June 26, 2012 — Researchers have identified a mechanism related to RNAi that scans for intruders not by recognizing dsRNA or some other aberrant feature of the foreign sequence, but rather by comparing the foreign ... > full storyMore:
