(PhysOrg.com) -- A tiny bit of genetic material with no previously known function may hold the key to stopping the spread of cancer, researchers at Yale School of Medicine and Sichuan University in Chengdu, China report in two papers in the September 7-11 issue of Proceedings of the National Academy of Sciences. http://www.physorg.com/news171895852.html Medicine & Health Fri, 11 Sep 2009 13:53:00 EST news171895852 A new study sheds light on a little understood biological process called quiescence, which enables blood-forming stem cells to exist in a dormant or inactive state in which they are not growing or dividing. According to the study's findings, researchers identified the genetic pathway used to maintain a cell's quiescence, a state that allows bone marrow cells to escape the lethal effects of standard cancer treatments. http://www.physorg.com/news150726406.html Biology Fri, 09 Jan 2009 12:26:46 EST news150726406
