UGA researchers make link between genetics, aging

(University of Georgia) University of Georgia scientists have shown a hormone instrumental in the aging process is under genetic control, introducing a new pathway by which genetics regulates aging and disease.Previous studies have found blood levels of this hormone, growth differentiation factor 11, decrease over time. Restoration of GDF11 reverses cardiovascular aging in old mice and leads to muscle and brain rejuvenation, a discovery listed as one of the top 10 breakthroughs in science in 201
