Molecular Communication from Skeletal Muscle to Bone: A Review for Muscle Derived Myokines Regulating Bone Metabolism
Besides the mechanical loading dependent paradigm, skeletal muscle also serves as an endocrine organ capable of secreting cytokines to modulate bone metabolism. In this review, we focused on reviewing the myokines involved in communication from skeletal muscle to bone, i.e. (1) myostatin and myostatin binding proteins including follistatin and decorin, (2) interleukins including interleukin 6 (IL 6) interleukin 7 (IL 7) and interleukin 15 (IL 15) (3) insulin like growth factor 1 (IGF 1) and its binding proteins, (4) other myokines including PGC 1a irisin system and osteoglycin (OGN) To better understand the molecular communication from skeletal muscle to bone, we have summarized the recent advances in muscle derived cytokines regulating bone metabolism in this review.
