By teasing apart the tagging events that result from RA from those that help cause it, the scientists say they were able to spot tagged DNA sequences that may be important for the development of RA. And they suspect their experimental method can be applied to predict similar risk factors for other common, noninfectious diseases, like type II diabetes and heart ailments. http://medicalxpress.com/news/2013-01-genes-regulatory-tags-conspire-rheumatoid.html Genetics Sun, 20 Jan 2013 13:00:19 EST news277899999
