Mothers can pass traits to offspring through bacteria’s DNA

February 16, 2015 By Michael C. Purdy ROBERT BOSTON Studying mice, Herbert W. Virgin, MD, PhD (left), and Thad Stappenbeck, MD, PhD, have shown that mothers can pass a trait to their offspring through the DNA of bacteria. The finding suggests that microbes may play a significant role in how genes influence illness and health in

Gene-silencing study finds new targets for Parkinson’s disease

National Institutes of Health -  Nature, November 24, 2013, Dr. Richard Youle, NINDS investigator, a leader of the study NIH study sheds light on treatment of related disorders Scientists at the National Institutes of Health have used RNA interference (RNAi) technology to reveal dozens of genes which may represent new therapeutic targets for treating Parkinson’s disease.

NIH director explains HeLa agreement

Descendants of Henrietta Lacks endorse controlled access to cell line genome after meetings with Francis Collins. By Ewen Callaway 07 August 2013 Francis Collins, who heads the US National Institutes of Health, reached an agreement with the Lacks family about publication of the HeLa cell genome. This week a policy allowing controlled access to the

Keeping the reserve force home

Jul 17 2013 Genomic imprinting maintains a reserve pool of blood-forming stem cells in mouse bone marrow KANSAS CITY, MO—Hematopoietic stem cells—bone marrow-derived adult stem cells that give rise to the wide variety of specialized blood cells—come in two flavors: the reserve force sits quietly waiting to be called upon while the active arm continually
