Cold shock RNA-binding protein RBM3 as a potential therapeutic target to prevent skeletal muscle atrophy

Abstract

Muscle atrophy is among the most common conditions during sickness, injury, aging and after orthopedic surgeries, and is associated with poor health outcomes. As such, it is important to understand the molecular machinery responsible for the control of muscle mass and function for development of therapeutic targets and strategies to combat muscle atrophy. We have identified the cold shock RNA binding protein, RNA-binding motif protein 3 (RBM3) as a critical regulatory node in the control of skeletal muscle mass and herein, we review our current knowledge of its actions in skeletal muscle. We also cover future directions of research and how this knowledge may translate into therapeutic interventions.
