Abstract:

 To study the localization of GHR and IGF-IR and the expression of GHR mRNA and IGF-IR mRNA in uterus of Jining Grey goats during postnatal development. Real-time flourescence quantitative PCR was used to detect the expression pattern of GHR mRNA and IGF-IR mRNA, and SABC method was applied to research the distribution of positive cells of GHR and IGF-IR in the uterus. GHR and IGF-IR were mainly localized in the cytoplasm of glandular epithelium, stromal cells, endothelium and smooth muscle cells of the uterus, occasionally in the nuclei. The changed trends on the positive cells of GHR and IGF-IR were similar with that on the expression of its mRNA. Although the expression of IGF-IR was less than that of GHR, the expression of GHR and IGF-IR both reached its peak on the puberty (D60) and the sexual maturity (D120)P<0.01, Then decreased and remained at a relatively stable level. GHR and IGF-IR play an important role in the growth of the uterus, and the puberty and the sexual maturity may be the fastest period of the uterus during postnatal development.
