摘要
鱼体内的物质、能量代谢既与摄入食物、环境因素及运动强度有关,也与内分泌调控因子的参与密切相关。Orexin是新近发现的一种能够调节机体摄食和能量代谢的下丘脑神经多肽物质。目前在人类和其他哺乳动物上的研究越来越多,而在海洋鱼类上的研究则比较少见。本文首先综述了鱼类Orexin的基因、结构、组织分布与生理功能等方面的最新研究成果,初步阐明了Orexin在鱼类摄食、营养、生活节律等生理学基础领域中的作用,可为今后鱼类养殖领域开展该项目的应用性研究奠定基础。
The conversion and metabolism of material and energy in vivo of fish, not only is related to intake of material, environmental factors and movement intensity, but also is controlled by the regulation of endocrine factors. As the feeding center, the hypothalamus plays a vital role in regulative process of energy metabolism. The secretion of some neurons in hypothalamus has effects on feeding adjustment, it temperature control and the cardiovascular activity adjustment, also can control the secretory action of pituitary. The secretion consequently can influence development, growth, reproduction and other activities of fish in direct or indirect way. In this article, the orexin genes, structure, organization distribution, physiological functions and other aspects have been summarized, research meaning in the field of physiological basis in the fish such as food intake, nutrition and life rhythm etc was also discussed. Moreover, the Orexin＇ s prospect of application in the aquaculture was introduced.
