摘要: 近年来,肠道菌群与宿主整个生命过程的相互作用受到越来越多的关注。肠道菌群可产生具有生物活性的可吸收代谢物,对维持宿主的健康起到了不可替代的作用。短链脂肪酸(short chain fatty acids,SCFAs)是肠道菌群发酵膳食纤维产生的主要代谢产物,主要包括乙酸、丙酸和丁酸,其作为介导肠道菌群与宿主各器官之间互作的媒介,广泛参与到宿主的生理活动中,其中也包括骨骼肌。骨骼肌作为机体最大和最重要的器官之一,维持其正常生理功能对于机体健康至关重要。目前关于SCFAs调控宿主的研究多集中在其他组织器官,调控骨骼肌的相关报道较少。鉴于SCFAs广泛的生理作用和骨骼肌自身的重要性,笔者就肠-肌轴理论、SCFAs的产生途径、转运及其对骨骼肌(质量、耐力、纤维特性)的调控作用进行综述,旨在加深对SCFAs调控骨骼肌这一生理过程的认识,为探索骨骼肌相关疾病的生物靶点提供新的思路。

Abstract: In recent years, more and more attention has been paid to the interaction between gut microbiota and the whole life process of the host.Gut microbiota plays an irreplaceable role in maintaining the health of the host mainly through the production of bioactive absorbable metabolites.Short chain fatty acids (SCFAs) are the main metabolites produced by gut microbiota fermentation of dietary fiber, mainly including acetate, propionate and butyrate.As a medium mediating the interaction between gut microbiota and various organs of the host, SCFAs are widely involved in the physiological activities of the host, including skeletal muscle.As one of the largest and most important organs of the body, skeletal muscle is very important for the health of the body to maintain its normal physiological function.At present, the studies on the regulation of host by SCFAs, mainly focus on other tissues and organs, while there are still few studies on the regulation of skeletal muscle.In view of the extensive physiological effects of SCFAs and the importance of skeletal muscle itself, the current research on the gut-muscle axis theory, the production pathway and transport of SCFAs, and the regulation of skeletal muscle (mass, endurance, fiber properties) as metabolites of intestinal flora were reviewed, and the current research status and future research directions were prospected.This study aims to deepen the understanding of the physiological process of SCFAs in regulating skeletal muscle, and provide new ideas for exploring biological targets of skeletal muscle-related diseases.

Key words: short-chain fatty acids (SCFAs); skeletal muscle; mass; endurance; fiber properties
