瘦素(leptin)是一种蛋白质激素。鱼类瘦素主要由肝合成和分泌,参与调节摄食、代谢、生长、免疫、繁殖、神经及造血细胞发育等。本文综述了瘦素的功能及作用机理、营养素对水生动物瘦素基因表达的影响,旨在进一步理解和深入探讨水生动物瘦素的作用及机理、营养素对水生动物瘦素基因表达的影响及其机制,这对理解摄食、能量代谢调控的机制具有科学理论意义;能为有计划、有目的、有效地控制水生动物体重、脂类沉积和能量代谢,根据需要生产理想、优质和健康的水产品提供基础依据,同时为调控人类肥胖、维护健康、提高生产力等提供参考。
Leptin is a protein hormone. Leptin is mainly synthesized and secreted by the liver and is involved in the regulation of feeding, metabolism, growth, immunity, reproduction, nerve and hematopoietic cell development. This review summarizes the function and mechanism of leptin and the effects of nutrients on leptin gene expression in aquatic animals. It aims to further understand and study the effects and mechanisms of leptin in aquatic animals and the effects of nutrients on leptin gene expression in aquatic animals Mechanism, which is of scientific theoretical significance for understanding the mechanism of ingestion and energy metabolism. It can control the weight, lipid deposition and energy metabolism of aquatic animals in a planned, targeted and effective manner, and produce ideal, high quality and healthy aquatic products Provide the basis for the foundation, at the same time to regulate human obesity, maintain health, improve productivity and provide a reference.
