| 摘 要： | 为进一步提高半滑舌鳎(Cynoglossus semilaevis)人工育苗技术的水平,对半滑舌鳎新型膜孕激素受体(mPR-like,mPRL)基因的表达特征和作用机制进行了研究.应用实时定量PCR方法分析mPRL mRNA在卵子形成过程中的时序表达,发现半滑舌鳎mPRL mRNA相对表达量的最高值出现在性成熟阶段卵巢的Ⅴ时相卵母细胞.原位杂交分析mPRL mRNA在繁殖相关组织的细胞学定位,发现mPRL mRNA分布在半滑舌鳎性成熟阶段卵巢的卵母细胞膜上;在脑的神经元和垂体内分散的细胞中,mPRL mRNA阳性信号较强.制备半滑舌鳎mPRL的多克隆抗体,采用Westem blotting方法检测半滑舌鳎mPRL蛋白在不同组织的表达特征,发现mPRL蛋白的表达量在卵巢、脑、垂体中相对较高,在肝脏、头肾、肾脏中表达量相对较少.免疫组化结果显示,半滑舌鳎mPRL蛋白在卵巢、脑和垂体的细胞学定位与mPRL mRNA定位一致.应用实时定量PCR和Westem blotting方法检测促性腺激素调控下半滑舌鳎不同时相卵母细胞mPRL基因mRNA和蛋白的表达变化,结果显示,促性腺激素对半滑舌鳎卵母细胞中mPRL基因mRNA和蛋白表达都有一定的上调作用,特别是对Ⅴ时相卵母细胞中mPRL mRNA和蛋白的表达量提升明显;发现表达量与促性腺激素调控作用具有剂量依存关系.半滑舌鳎mPRL在繁殖相关组织的表达特征表明其通过脑-垂体-卵巢轴参与繁殖调控,同时也揭示了mPRL介导卵母细胞成熟机制.
