【摘要】：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。
[Abstract]:Micronutrients and fats are important nutrients in the metabolism of animals. Only by meeting the nutritional needs of growth and development can animals carry out all kinds of life activities smoothly and, more importantly, they also act as regulators of gene expression. It is possible to regulate the expression of animal genes in many ways and at various levels. The content and type of nutrients in the diet of animals will affect the gene expression of animals, which will lead to changes in metabolic pathways and efficiency of the animal body. In recent years, with the development of molecular biotechnology, the regulation of nutrients on animal gene expression and its mechanism have been gradually revealed. New research findings have sprung up. The authors review progress in the regulation of micronutrients and fats on gene expression in animals, in order to provide a theoretical basis for more accurate and rational determination of animal nutrient requirements. The prospect of research and application of nutrient regulation gene expression is also discussed.
