摘要: 旨在检测黄体生成素受体(Luteinizing hormone receptor,LHR)基因在牦牛发情周期不同阶段生殖系统中的表达。实验选取青海健康的处于卵泡期和黄体期的2岁龄雌性牦牛各3头,根据黄牛LHR基因序列5'端和3'端的保守序列设计特异性引物,利用实时荧光定量PCR(RT-qPCR)法分析牦牛发情周期不同阶段,生殖系统中LHR基因的相对表达量。结果显示,LHR基因在牦牛发情周期不同阶段生殖系统中的表达量存在差异,卵巢和输卵管中卵泡期LHR基因的表达量高于黄体期,黄体期子宫中LHR基因的表达量高于卵泡期。研究表明牦牛在发情周期不同阶段生殖系统中LHR基因的表达量存在差异,提示LHR在牦牛的繁殖过程中对生殖系统具有重要的调节作用。

Abstract: This experiment was conducted to study the differences in expression of luteinizing hormone receptor(LHR)gene in the reproduction of yak during the estrous cycle. Three 2-year female yaks in each phase(follicular and luteal phase)from Qinghai Province were selected for the experiment. Specific primers were designed on the basis of 5' and 3' end conservative LHR gene sequence of cattle. The comparative expression quantity of LHR gene in different phases of the reproductive system of yak was analyzed by real time quantitative PCR(RT-qPCR). The results showed that the comparative expression quantity of LHR gene in the reproductive system of yak during the estrous cycle were different, the expressions of LHR gene in ovary and oviduct were higher during the follicular phase than the luteal phase, and the expression of LHR gene in uterus was higher during the luteal phase than the follicular phase. Our findings showed that the expression of LHR gene in the reproductive system of yak during the estrous cycle was different. It implies that the LHR plays vital regulating role in the reproductive system during the reproduction of yak.
