Abstract

Hydrogen sulfide (H<sub>2</sub>S) has been known as a gasotransmitter, and it contributes to various physiological and pathological processes. Multiple enzymes such as cystathionine-β-synthase (CBS), cystathionine-γ-lyase (CSE) and 3-Mercaptopyruvate sulfurtransferase (MST) produce endogenous H<sub>2</sub>S, and these are differentially expressed in the various tissue systems including the skeletal system. However, abnormal H<sub>2</sub>S production is associated with deregulation of the signaling cascade and imbalanced tissue homeostasis. Several studies have previously provided evidence showing the essential regulatory action of H<sub>2</sub>S in skeletal homeostasis. In this review, we have emphasized the novel function of H<sub>2</sub>S in both bone and skeletal muscle anabolism, in particular. Additionally, we also reviewed the molecular and epigenetic basis of H<sub>2</sub>S signaling in bone development and skeletal muscle function.
