Abstract

As a key coordinator of metabolism, AMP-activated protein kinase (AMPK) is vitally involved in skeletal muscle maintenance. AMPK exerts its cellular effects through its function as a serine/threonine protein kinase by regulating many downstream targets and plays important roles in the development and growth of skeletal muscle. AMPK is activated by phosphorylation and exerts its function as a kinase in many processes, including synthesis and degradation of proteins, mitochondrial biogenesis, glucose uptake, and fatty acid and cholesterol metabolism. Skeletal muscle atrophy is a result of various diseases or disorders and is characterized by a decrease in muscle mass. The pathogenesis and therapeutic strategies of skeletal muscle atrophy are still under investigation. In this review, we discuss the role of AMPK in skeletal muscle metabolism and atrophy. We also discuss targeting AMPK for skeletal muscle treatment, including exercise, AMPK activators including 5-amino-4-imidazolecarboxamide ribonucleoside and metformin, and low-level lasers. These studies show the important roles of AMPK in regulating muscle metabolism and function; thus, the treatment of skeletal muscle atrophy needs to take into account the roles of AMPK.
