反刍动物营养生理的分子生物学研究与展望

MINI-REVIEW AND PROSPECT OF MOLECULAR BIOLOGY RESEARCH ON NUTRITION PHYSIOLOGY OF RUMINANTS

本综述讨论了反刍动物营养生理的分子生物学研究。许多研究证明 ,营养可以影响反刍动物生长轴、生殖轴(有关激素、受体) ,代谢以及有关酶的基因表达。机理研究认为营养因子除了作用于基因启动子外 ,还涉及转录后的调节。这是当前营养生理学的重要研究领域 。

A review about research on molecular biology in nutritional physiology of ruminants is given in this paper.A lot of results show that the nutrition can influence gene expression of ruminants including some hormones and their receptors in somatotropic axis,gonadotropic axis,and the key enzymes involved in metabolism.The nutritional factors not only act on gene promoters but also affect the post_transcriptional processes.This is a major area of nutritional physiology in the future,which will contribute to the development of elementary research and new biotechnology.
