Abstract
AbstractSkeletal muscle wasting is a complicated metabolic syndrome accompanied by multiple diseases ranging from cancer to metabolic disorders and infectious conditions. The loss of muscle mass significantly impairs muscle function, resulting in poor quality of life and high mortality of associated diseases. The fundamental cellular and molecular mechanisms inducing muscle wasting have been well established, and those related pathways can be activated by a variety of extracellular signals, including inflammatory cytokines and catabolic stimuli. As an emerging messenger of cell‐to‐cell communications, extracellular vesicles (EVs) also get involved in the progression of muscle wasting by transferring bioactive cargoes including various proteins and non‐coding RNAs to skeletal muscle. Like a double‐edged sword, EVs play either a pro‐wasting or anti‐wasting role in the progression of muscle wasting, highly dependent on their parental cells as well as the specific type of cargo they encapsulate. This review aims to illustrate the current knowledge about the biological function of EVs cargoes in skeletal muscle wasting. Additionally, the potential therapeutic implications of EVs in the diagnosis and treatment of skeletal muscle wasting are also discussed. Simultaneously, several outstanding questions are included to shed light on future research.
