Muscle-Specific SIRT1 Gain-of-Function Increases Slow-Twitch Fibers and Ameliorates Pathophysiology in a Mouse Model of Duchenne Muscular Dystrophy

17 Jul 2014

Abstract excerpt

SIRT1 is a metabolic sensor and regulator in various mammalian tissues and functions to counteract metabolic and age-related diseases. Here we generated and analyzed mice that express SIRT1 at high levels specifically in skeletal muscle. We show that SIRT1 transgenic muscle exhibits a fiber shift from fast-to-slow twitch, increased levels of PGC-1α, markers of oxidative metabolism and mitochondrial biogenesis,...
