摘要:

旨在探讨济宁青山羊出生后发育过程中雌激素受体(Estrogen receptor, ERα和ERβ)和孕激素受体(Progesterone receptor, PR)在子宫的定位及其mRNA的表达规律。利用SABC法检测ERα、ERβ和PR在不同日龄组子宫的分布;以GAPDH为内参基因,qRT-PCR法检测3mRNA的相对表达量。结果显示,ERα、ERβ PR阳性物质主要见于腔上皮、腺上皮、基质、血管内皮和平滑肌细胞的胞核中,偶见胞质阳性着色。ERα、ERβ和PR阳性细胞光密度与其mRNA表达趋势基本一致,但ERβ低于ERα。ERα和ERβ在出生当天~30日龄处于低水平,60日龄开始上升,90120日龄达到高峰,以后维持在高水平状态;PR在出生当天较高,而在30日龄处于最低水平,初情期(60日龄)后逐渐升高,并在性成熟(120日龄)和性成熟后(180日龄)出现2个高峰。ERα、ERβ和PR参与调节子宫内膜与肌层的增殖和分化。

Abstract:

To detect the location of ERα, ERβ and PR and the expression of ERα, ERβ and PR mRNA in the uterus of Jining Grey goats during postnatal development. In the uterus of different group, the SABC methods were used to study the distribution of ERα, ERβ and PR, and the real time fluorescent quantitative PCR were used to research the relative expression of ERα, ERβ and PR mRNA with GAPDH as an internal gene. ERα,ERβ and PR were malinly localized in the nuclei of the luminal epithelium, glandular epithelium, stromal cells, endothelium and smooth muscle cells of the uterusand occasionally in the cytoplasm. The trends of the optical density in the immunopositive cells of ERα, ERβ and PR were similar with that of the expression of ERα, ERβ and PR mRNA. But the level of the expression of ERβ was less than that of ERα. From the birth day to the 30th day, the expression of ERα and ERβ remained at a lower level then increased gradually on the 60th day, ERα and ERβ reached its peak from the 90th day to the 120th day, and afterwards maintained at a high level. While the expression of PR was higher on the birth day, than reached its lowest level on the 30th day and significantly increased after puberty, and two peaks were found during the sexual maturity and maturation. ERα, ERβ and PR have an important role in regulating the proliferation and differentiation of the endometrial and the myometrial.
