In yet another study of the benefits of red wine, Harvard Medical School researchers have reported that increasing the levels of sirtuin genes protects against aging by similar mechanisms in both very simple organisms like yeast, and in mammals. “This is the first potentially fundamental, root cause of aging that we’ve found,” said professor of pathology David Sinclair in a Harvard press release. “There may very well be others, but our finding that aging in a simple yeast cell is directly relevant to aging in mammals comes as a surprise.” When stimulated by the red wine chemical resveratrol, or by caloric restriction, sirtuins seem to have positive effects on aging and health, according to Sinclair’s research. Sirtris Pharmaceuticals is working with these results to create a pill that targets Diabetis and other diseases related to aging, as discussed in the following ScienCentral clip.
