"Mice are much closer evolutionarily to humans than any previous model organism treated by this molecule, which offers hope that similar impacts might be seen in humans without negative side-effects," says co-senior author David Sinclair, HMS associate professor of pathology, and co-director of the Paul F. Glenn Labs for the Biological Mechanisms of Aging.
"After six months, resveratrol essentially prevented most of the negative effects of the high calorie diet in mice," said Rafael de Cabo, Ph.D., the study's other co-senior investigator from the National Institute on Aging's Laboratory of Experimental Gerontology, Aging, Metabolism, and Nutrition Unit. "There is a lot of work ahead that will help us better understand resveratrol's roles and the best applications for it."
Resveratrol is found in red wines and produced by a variety of plants when put under stress. It was first discovered to have an anti-aging properties by Sinclair, other HMS researchers, and their colleagues in 2003 and reported in Nature. The 2003 study showed that yeast treated with resveratrol lived 60 percent longer. Since 2003, resveratrol has been shown to extend the lifespan of worms and flies by nearly 30 percent, and fish by almost 60 percent. It has also been shown to protect against Huntington's disease in two different animal models (worms and mice).
