摘要: [目的]利用雌二醇对绵羊输卵管上皮细胞进行刺激,检测与分析绵羊输卵管上皮细胞pik3r3、Akt、mapk3基因mRNA及蛋白表达的变化。[方法]以5代内的绵羊输卵管上皮细胞作为研究对象,通过qPCR及Western blot检测添加10-8 mol/L的雌二醇(以等量培养基替代雌二醇作为对照组)作用0、1.0、1.5、2.0、2.5、3.0、3.5、4.0、4.5、5.0 h后输卵管上皮细胞pik3r3、Akt、mapk3基因mRNA及蛋白的表达情况。[结果]在绵羊输卵管上皮细胞中添加10-8 mol/L雌二醇后,随着作用时间的延长,pik3r3、Akt、mapk3基因mRNA及蛋白的表达量整体呈先升高、后降低趋势。与作用0 h相比,pik3r3基因的mRNA表达量(P<0.01)及蛋白表达量(P<0.05)在雌二醇作用1.5 h时达到最高峰,Akt、mapk3基因的mRNA表达量(P<0.01)及蛋白表达量(P<0.05)在雌二醇作用2.5 h时达到最高峰。雌二醇作用3.0 h时,pik3r3、Akt、mapk3基因的mRNA表达量相比0 h都显著(P<0.05)提高。[结论]输卵管上皮细胞中pik3r3、Akt、mapk3基因的表达受到雌二醇调控。高浓度雌激素促进pik3r3、Akt、mapk3基因的高表达,这可能与生殖道的天然防御有关,并可能通过该途径提高机体自身免疫应答能力。

Abstract: [Objective] To assess the mRNA and protein expression of pik3r3, Akt and mapk3 genes in sheep oviduct epithelial cells after stimulation with estradiol. [Method] The mRNA and protein expression levels of pik3r3, Akt and mapk3 genes in oviduct epithelial cells within five passages were detected by qPCR and Western blot respectively after incubation with 10-8 mol/L estradiol (equivalent amount of medium instead of estradiol were used as the control group) for 0, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, and 5.0 h. [Result] After adding 10-8 mol/L estradiol to sheep oviduct epithelial cells, the mRNA and protein expression levels of pik3r3, Akt and mapk3 genes increased first and then reduced as the incubation time progressed. The mRNA expression (P<0.01) and protein expression (P<0.05) of the pik3r3 gene peaked after 1.5 h treatment with estradiol, whereas the mRNA expression (P<0.01) and protein expression (P<0.05) of the Akt and mapk3 genes peaked at 2.5 h treatment with estradiol. The mRNA expression of pik3r3, Akt and mapk3 genes all significantly (P<0.05) increased after 3.0 h of estradiol treatment. [Conclusion] Estradiol regulates the expression of pik3r3, Akt and mapk3 genes in sheep oviduct epithelial cells. High levels of estrogen facilitate the expression of pik3r3, Akt and mapk3 genes, which is linked to the innate immune defence in the reproductive tract, and may improve the autoimmune response via this mechanism.
