微量营养素与脂肪对动物基因表达的调控作用

Regulation Effect of Trace Nutrients and Fat on Manipulation of Animal Gene Expression

微量营养素与脂肪作为动物新陈代谢的重要营养物质,只有满足生长发育的营养需要,动物才能平稳的进行各项生命活动,更重要的是它们还作为基因表达的调控物,可以在多途径、多水平对动物基因表达进行调控。动物日粮中营养素含量和类型都会影响动物的基因表达,进而导致动物机体的代谢途径和效率发生改变,最终影响动物的营养需求和生产性能。近年来,随着分子生物技术的发展,营养素对动物基因表达的调控作用及其机制逐渐被揭示出来,新的研究发现纷纷涌现。作者针对微量营养素与脂肪对动物基因表达的调控作用研究进展进行综述,旨在为更准确、更合理地确定动物对营养素的需要量提供理论依据。此外,本综述还对营养素调控基因表达的研究与应用前景作了展望。

Trace nutrients and fat,as important nutrients for animal metabolism,are vital for the growth and development of animals.Importantly,they can regulate gene expression in different ways and levels.The alteration of animal gene expression can affect the animal＇s nutritional requirements and growth performance by changing the nutrient metabolic pathway and efficiency.With the development of animal nutrition and molecular biology,the mechanism of nutrients regulating gene expression is gradually revealed.In this paper,the effects of trace nutrients and fat regulating gene expression were reviewed aiming to provide a theoretical basis for the determining of animal nutrients requirement more accurately and scientifically.In addition,the application prospects of nutrients regulating gene expression were also discussed.
