摘　　要：肌肉生长抑制素是转化生长因子β超家族成员之一,具有众多的生理功能。近来的研究表明,肌肉生长抑制素除对肌肉生长有负调控作用外,还对脂肪的沉积和骨骼的生长发育具有调节作用,甚至还能影响肌腱和韧带的强硬度。本文主要从肌肉生长抑制素的结构、基因表达及其对动物肌肉、脂肪和骨骼的作用等方面进行综述。Myostatin(MSTN),a member of the transforming growth factor-β superfamily,has many physiological functions.Besides the negative regulation of muscle growth by MSTN,recent researches showed that MSTN could regulate the fat deposition and skeletal growth,and even control the strength of tendon and ligament.Structure and regulation of gene expression of myostatin and its effects on muscle,fat and bone of animals were mainly reviewed in this paper.
