雌激素受體在間情期綿羊輸卵管上皮細(xì)胞中的表達(dá)
[Abstract]:To investigate the expression and localization of membrane estrogen receptor (GPER (G protein-coupled estrogen receptor 1) and estrogen nuclear receptor (ER 偽 er 尾) in ovine oviductal epithelial cells, and to investigate the expression of these receptors in ovine oviduct during interoestrous period. The expression differences of mRNA and protein levels of three receptor genes were detected by RT-qPCR and Western blotting, and the three receptor genes in oviducts were located by immunohistochemical method and the results were analyzed by optical density. The results showed that the relative expression of GPER in oviduct epithelial cells was higher than that in ER 偽 -ER 尾 (P0.01) and ER 尾 (P0.05). Immunohistochemical results showed that GPER was widely distributed in ovine oviduct epithelial cells, mainly located in cell membrane and cytoplasm. However, ER 偽 and ER 尾 mainly distributed in the nuclei of ovine oviduct epithelial cells. The results of optical density analysis of positive cells were consistent with those of fluorescent quantitative RT-qPCR. The results showed that there were three estrogen receptors of GPER,ER 偽 -ER 尾 in oviductal epithelial cells of sheep during interoestrous period, and the relative expression of GPER was the highest and the lowest was the average optical density of ER 尾.
