Description
Apoptosis is a highly conserved type of cell death that plays a critical role in tissue homeostasis and disease-associated processes. Skeletal muscle is unique with respect to apoptotic processes, given its multinucleated morphology and its apoptosis-associated differences related to muscle and (or) fiber type as well as mitochondrial content and (or) subtype. Elevated apoptotic signaling has been reported in skeletal muscle during aging, stress-induced states, and disease; a phenomenon that plays a role in muscle dysfunction, degradation, and atrophy. Exercise is a strong physiological stimulus that can influence a number of extracellular and intracellular signaling pathways, which may directly or indirectly influence apoptotic processes in skeletal muscle. In general, acute strenuous and eccentric exercise are associated with a proapoptotic phenotype and increased DNA fragmentation (a hallmark of apoptosis …
