SAGE Crossroads On Mitochondria

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

The latest SAGE Crossroads weekly article discusses mitochondria, our cellular powerhouses: "Recent studies have implicated unchecked mitochondrial decay in Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), obesity, diabetes, and aging itself ... some studies have suggested that one of our most popular all-purpose panaceas--exercise--acts in part by slowing and perhaps suspending the mitochondrial countdown." Repairing, replacing or moving mitochondrial DNA is on biogerontologist Aubrey de Grey's engineering list. If, for example, we could move mitochondrial DNA into the comparatively well-protected cell nucleus, we would be in much better shape to resist ongoing damage.
