摘要: 旨在研究p38MAPK在母牦牛主要生殖器官中的表达情况,了解其表达差异性,为牦牛的繁殖性能研究提供相关基础资料。本研究采集卵泡期、黄体期、妊娠期成年健康母牦牛(各2头)主要生殖器官样品,免疫组化技术检测p38MAPK蛋白的表达部位;qRT-PCR和Western-blot技术对其基因和蛋白进行相对表达量测定。结果:1)免疫组化结果显示,p38MAPK蛋白在牦牛的卵巢、输卵管和子宫均呈阳性表达;2)qRT-PCR结果表明,p38MAPK基因在卵巢中的表达量卵泡期显著高于妊娠期(P<0.05);在输卵管中的表达量黄体期显著高于卵泡期和妊娠期(P<0.05);在子宫中的表达量妊娠期极显著高于卵泡期和黄体期(P<0.01);3)Western-blot结果显示,p38MAPK蛋白在卵巢中的表达量卵泡期极显著高于黄体期和妊娠期(P<0.01);在输卵管中的表达量黄体期极显著高于卵泡期和妊娠期(P<0.01);在子宫中的表达量妊娠期极显著高于卵泡期和黄体期(P<0.01)。结果表明,p38MAPK在母牦牛同一生殖器官的不同繁殖阶段其表达存在差异性,其可能参与了牦牛卵泡发育、黄体功能发挥以及胚胎着床和发育等一系列生殖过程,为牦牛的繁殖性能研究提供相关基础资料。

Abstract: The aim of this study was to explore the expression of p38 mitogen-activated protein kinase (p38MAPK) protein and gene in the main reproductive organs of female yaks, accumulate some fundamental data for comprehending the role of p38MAPK in yak reproductive activity. The samples of main reproductive organs of adult healthy female yak during follicular phase, luteal phase and gestation period(2 each) were collected. Immunohistochemical method was used to locate the expression site of p38MAPK protein in the main reproductive organs of female yaks. The relative expression levels of the p38MAPK gene and protein were detected by qRT-PCR and Western-blot technique, respectively. The results showed that:1) The results of immunohistochemistry showed that p38MAPK protein was positively expressed in ovary, oviduct and uterus in female yak. 2) qRT-PCR results showed that the expression of p38MAPK gene in the ovary was significantly higher during follicular phase than that during gestation period(P<0.05). The expression of p38MAPK gene in oviduct was significantly higher during the luteal phase than that during the follicular phase and gestation period (P<0.05). The expression of p38MAPK gene in the uterus was significantly higher during gestation period than that during follicular phase and luteal phase (P<0.01). 3) The results of Western-blot showed that the expression of p38MAPK protein in the ovary during the follicular phase was significantly higher than that during the luteal phase and gestation period (P<0.01). The expression level of p38MAPK protein in the oviduct during the luteal phase was significantly higher than that during the follicular phase and gestation period (P<0.01). The expression of p38MAPK protein in the uterus during gestation period was significantly higher than that during follicular phase and luteal phase (P<0.01). In conclusion, these results suggest that p38MAPK may be involved in the regulation of reproductive processes that includes follicular development, luteal function and embryo implantation and embryo development. These data provide basic information for researching the reproductive mechanism of female yak.
