摘要: 肌肉组织分为骨骼肌、心肌和平滑肌3种类型。其中骨骼肌是畜禽最大的器官,约占畜禽身体质量的40%,它由大小、形状及肌肉收缩蛋白含量不同的肌纤维构成,对维持身体姿势、呼吸和体温调节是必不可少的。在肌纤维发育的各阶段,复杂的外在和内在机制共同调控着肌肉的发生,相关的信号机制在这当中起着决定性作用。畜禽的骨骼肌是主要的肉产品来源,而肉质性状的改善也是每个畜禽场的重要目标,因此对肌纤维的发生及相关机制的全面了解是很有必要的。本文通过整合1987—2022年国内外肌纤维研究相关文献,对肌纤维的发生、类型及调控机制进行了综述,重点介绍了与畜禽肌纤维发育规律相关的基因及信号通路,并对目前畜禽肌纤维调控机制研究存在的问题提出了建议和未来研究的方向进行了展望。

Abstract: Muscle tissue is divided into 3 types:skeletal muscle, cardiac muscle and smooth muscle. Among them, skeletal muscle is the largest organ of livestock and poultry, accounting for about 40% of the body mass, and it consists of muscle fibers with different sizes, shapes and contents of muscle contractile proteins, which are essential for maintaining body posture, respiration and thermoregulation. A complex combination of extrinsic and intrinsic mechanisms regulates myogenesis at all stages of muscle fiber development, and relevant signaling mechanisms play a decisive role in this process. Skeletal muscle of livestock and poultry is the main source of meat products and the improvement of meat quality traits is an important goal of every livestock farm, a comprehensive understanding of myogenesis and related mechanisms is necessary. In this paper, the occurrence, types and regulatory mechanisms of muscle fibers were reviewed by integrating the literature related to muscle fiber research at domestic and international from 1987 to 2022, highlighting the genes and signaling pathways related to the developmental patterns of muscle fibers in livestock and poultry, and presenting the problems in current research on the regulatory mechanisms of muscle fibers in livestock and poultry to provide an outlook on the future research directions.

Key words: muscle fiber, muscle fiber development, molecular regulation, signaling pathway, gene
