Anti-cancer drug prevents, reverses cardiovascular damage in mouse model of premature aging disorder
An experimental anti-cancer drug can prevent -- and even reverse -- potentially fatal cardiovascular damage in a mouse model of progeria, a rare genetic disorder that causes the most dramatic form of human premature aging, National Institutes of Health (NIH) researchers reported today.
