Myogenic differentiation during regrowth of atrophied skeletal muscle is associated with inactivation of GSK-3β

Abstract excerpt

Muscle atrophy contributes to morbidity and mortality in aging and chronic disease, emphasizing the need to gain understanding of the mechanisms involved in muscle atrophy and (re)growth. We hypothesized that the magnitude of muscle regrowth during recovery from atrophy determines whether myonuclear accretion and myogenic differentiation are required and that insulin-like growth factor (IGF)-I/Akt/glycogen...
