Abstract: Muscle loses normal function after skeletal muscle atrophy that will greatly reduce the quality of personal life. There is no effective way to treat muscle atrophy currently. microRNA (miRNA) as a small molecule of non-coding RNA brings new hope for the treatment of muscular atrophy. The mechanism of miRNA regulating muscle atrophy mainly includes: regulating abnormal muscle protein metabolism by ubiquitin-proteasome system (UPS) and mammalian target of rapamycin pathway (IGF/PI3K/Akt/mTOR), inhibiting abnormal apoptosis of muscle cells by inhibiting the expression of apoptotic factors, promoting muscle regeneration by regulating myogenic factor expression, and promoting angiogenesis by promoting the expression of angiogenic factors, and so on.

Key words: microRNA, muscle atrophy, review
