In and Out: steroid hormone and chromatin remodelling factors in female Drosophila GSC

November 4th, 2010 · No Comments · Stem Cell

A latest article in Cell Stem Cell by Dr. Drummond-Barbosa Group in Vanderbilt University Medical Center, reports that the systemic factor ecdysone, a steroid hormone, and  ISWI / Nurf301 act together to regulate the female GSC self-renewal and proliferation independently of insulin signaling in Drosophila. It broadens our view of the mechanisms underlying GSC regulation [...]

Link between Germline Stem Cell Maintenance and Lifespan Extension by Dietary Restriction?

October 25th, 2010 · No Comments · Stem Cell

It is well-known that lifespan is extended under dietary restriction (DR) to overcome the growth disadvantage. However, the underlying mechanisms remain largely unknown. A latest short article in Aging Cell reveals a potential link between lifespan and germline stem cell (GSC) in male Drosophila. – GeneDog
