Regulation and Role of p21 in Skeletal Muscle Atrophy

Skeletal muscle atrophy is a common and debilitating disease with many diverse causes. Despite the broad clinical impact, there are currently no pharmacologic therapies to prevent or reverse skeletal muscle atrophy. This is partly explained by the fact that the molecular basis of skeletal muscle atrophy remains largely unexplored and thus poorly understood. The transcription factor ATF4 has emerged as a key driver of muscle atrophy in several clinically important scenarios. Previous work has shown that this effect is mediated through increased expression of the ATF4 target gene p21 in skeletal muscle fibers. My studies build upon initial findings to more deeply investigate and understand the upstream mechanisms that control p21 expression in skeletal muscle, the pathophysiological consequences of a targeted reduction in muscle p21 expression and the downstream mechanism by which p21 promotes muscle atrophy.
