摘要:

 旨在探讨济宁青山羊生后发育过程中生长激素受体(Growth hormoneGHR)和胰岛素样生长因子I受体(Insulin-like growth factor-IIGF-IR)在子宫的分布及其mRNA的表达规律。运用实时荧光定量PCR技术,检测GHR mRNAIGF-IR mRNA的表达规律;SABC法检测GHRIGF-IR免疫阳性细胞在子宫的分布。结果表明,GHRIGF-IR免疫阳性染色主要见于子宫腺管上皮、基质、血管内皮和子宫平滑肌细胞的胞质中,偶见胞核着色。GHRIGF-IR的阳性细胞数与其mRNA表达的变化趋势基本一致,且IGF-IR低于GHR GHRIGF-IR在初情期(60日龄)和性成熟(120日龄)达到高峰(P<0.01),120日龄后下降,并维持在一个相对稳定的水平。GHRIGF-IR在子宫的生长发育过程中起着重要作用,且初情期和性成熟期可能是济宁青山羊生后子宫发育最快的时期。

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.
