Abstract:

SMAD3 gene is one of the members of the SMADs gene family,and the SMAD3 protein which encoded by SMAD3 gene,is the special intracellular signal transduction molecule of TGF-β super gene family.Not only SMAD3 gene participates in regulating many aspects of important physiological processes via the superfamily of TGF-β,such as disease,immune regulation,growth and development,wound healing,development and maintenance of cartilages and bones,but also involves in regulating physiological activities in animal,for example,the proliferation,differentiation,maturation,adhesion,atresia,apoptosis of germ cells,and secretion of steroid hormone.Therefore,it's of great significance to understand the structure and function of SMAD3 gene for the researches relating to animal growth,development and reproduction.This review sketched the structure,function,mechanism of SMAD3 gene,and analysized its research progress of the application in livestock production.It showed that a large number of researches about the application of SMAD3 gene in animal production was mainly focus on aspects of growth regulation,development,cell immunity and apoptosis,hormone secretion and reproductive performance of vertebrate (pigs,cattle,sheep,chickens,etc).Regulations of SMAD3 gene in disease,growth and development,fat deposition and reproductive performance were still hot in domestic and abroad.However,the precise molecular regulation mechanism of this gene on disease occurrence,growth and reproductive performance remains to be further researched.

Key words: SMAD3 gene; transforming growth factor-β (TGF-β); mechanism; animal production
