Overactive bone morphogenetic protein signaling in heterotopic ossification and Duchenne muscular dystrophy

Abstract

Bone morphogenetic proteins (BMPs) are important extracellular cytokines that play critical roles in embryogenesis and tissue homeostasis. BMPs signal via transmembrane type I and type II serine/threonine kinase receptors and intracellular Smad effector proteins. BMP signaling is precisely regulated and perturbation of BMP signaling is connected to multiple diseases, including musculoskeletal diseases. In this review, we will summarize the recent progress in elucidation of BMP signal transduction, howoveractiveBMPsignaling is involved in the pathogenesis of heterotopic ossification andDuchennemuscular dystrophy, and discuss possible therapeutic strategies for treatment of these diseases. © The Author(s) 2012.
