Random errors in protein synthesis activate an age-dependent program of muscle atrophy in mice
Past, present, and future perspective of targeting myostatin and related signaling pathways to counteract muscle atrophy
Myostatin was identified more than 20 years ago as a negative regulator of muscle mass in mice and cattle. Since then, a wealth of studies have uncovered the potential involvement of myostatin in muscle atrophy and sparked interest in myostatin as a promising therapeutic target to counteract decline of muscle mass in patients afflicted with different muscle-wasting conditions. Insight in the molecular mechanism of myostatin signaling and regulation of myostatin activity has resulted in the identification of specific treatments to inhibit myostatin signaling and related signaling pathways. Currently, several treatments that target myostatin and related proteins have been evaluated in preclinical animal models of muscle wasting, and some potential therapies have progressed to clinical trials. However, studies also revealed potential downsides of myostatin targeting in skeletal muscle and other tissues, which raises the question if myostatin is indeed a valuable target to counteract muscle atrophy. In this review we provide an updated overview of the molecular mechanisms of myostatin signaling, the preclinical evidence supporting a role for myostatin and related proteins in muscle atrophy, and the potential issues that arise when targeting myostatin. In addition, we evaluate the current clinical status of different treatments aimed at inhibiting myostatin and discuss future perspectives of targeting myostatin to counteract muscle atrophy
