Sirt1 regulates aging and resistance to oxidative stress in the heart.


Silent information regulator (Sir)2, a class III histone deacetylase, mediates lifespan extension in model organisms and prevents apoptosis in mammalian cells. However, beneficial functions of Sir2 remain to be shown in mammals in vivo at the organ level, such as in the heart. We addressed this issue by using transgenic mice with heart-specific… (More)
