| 摘 要： | 类胰岛素生长因子-I(IGF-I)是促合成代谢、促有丝分裂和抗细胞凋亡的因子。妊娠早期母猪体内有大量IGF-I表达,对胚胎发育有重要作用。营养水平影响IGF-I及其mRNA的表达。本文介绍了母猪卵巢、输卵管和子宫内IGF-I及其mRNA的表达特点,重点阐述了营养水平对母猪IGF-I及其mRNA表达的调控与可能机制。

| Abstract: | Insulin-like growth factor-I is an important mediator of anabolism,mitosis and apoptosis of cell.IGF-I is expressed in organism of sows or gilts,and involved in development of embryo during early gestation.Concentration of IGF-I and expression of IGF-I mRNA are affected by levels of nutrition.In this article,the expressive characters of IGF-I and IGF-I mRNA in ovary,oviduct and uterus of sows or gilts are reviewed,and the nutritional regulation on their expression and possible mechanism are emphasized.[Chinese Journal of Animal Nutrition,2006,18(Suppl):341-346] |
