These findings suggest a provocative general principle at work: Molecular signals from the reproductive system affect aging and metabolism in animals -- and possibly in humans. The work also proposes a new mechanism of how this control may occur.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/277313607" height="1" width="1" /></p> http://science-nature.marc8.com/eliminating-germline-lengthens-fly-lifespan-does-reproductive-s#comments Top stories germline insulin production molecular signals reproductive system stem cells http://science-nature.marc8.com/crss/node/4018 Fri, 25 Apr 2008 08:00:00 -0500 admin 4018 at http://science-nature.marc8.com
