摘要: 生长轴是动物体内下丘脑-垂体-靶器官一系列激素及其受体所组成的神经内分泌系统。通过提高生长轴中生长激素(GH)和胰岛素样生长因子-Ⅰ(IGF-Ⅰ)水平,促进增重、提高饲料转化率和改善肉品质,是畜禽生长调控的一种新途径。GH通过IGF-Ⅰ介导调节动物生长和细胞分化等,文章综述了GH/IGF-Ⅰ轴的组成、功能,以及GH调控IGF-Ⅰ表达的分子机理。

Abstract: The growth axis is a neuroendocrine system, which is composed of series of hormones and their receptors from the hypothalamus-pituitary-target organ in vivo of animals. Increasing the GH and IGF-Ⅰ levels in the growth axis, to promote weight gain, feed conversion rate and improve meat quality, which is a new approach of animal growth regulation. GH mediated by IGF-Ⅰ regulates animal growth and cell differentiation. We will discuss the constitution and function of GH/IGF-Ⅰ axis, and mechanism of growth hormone regulation of IGF-Ⅰ expression in this review.

Key words: growth hormone; IGF-Ⅰ gene; regulation of gene expression
