Anabolic and Catabolic Signaling Pathways that Regulate Skeletal Muscle Mass

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

Skeletal muscle mass is primarily dictated by the balance between the rates of protein synthesis and degradation. Over the last decade, significant progress has been made in defining the anabolic and catabolic signaling pathways that control skeletal muscle mass through the regulation of protein synthesis and degradation. The purpose of this review is to briefly describe known and emerging signaling pathways involved in the regulation of skeletal muscle mass. An important theme that has come to light is the degree of crosstalk between anabolic and catabolic signaling pathways involved in the control of skeletal muscle hypertrophy and atrophy, respectively. A better understanding of the anabolic and catabolic signaling pathways that regulate skeletal muscle mass will provide a critical foundation for the development of more effective training programs and nutritional aids to enhance athletic performance.
