摘要:

旨在探究卵泡发育相关基因在牛发情周期内第一卵泡波中优势卵泡(Dominant follicles,DF)和从属卵泡(Subordinate follicles,SF)颗粒细胞中表达差异,进而筛选影响牛卵泡发育的相关基因。通过GEO数据库与基因功能分析筛选与牛卵泡发育相关基因,采用qRT-PCR检测牛第一卵泡波DF和SF颗粒细胞中各基因的表达差异。结果显示:筛选出6个候选基因(SFRP2、CPEB1、PRKAG2、MAPK8、PPP2R2APRSS23)与牛卵泡发育有关;qRT-PCR检测,CPEB1在DF中的表达量极显著高于SF(P<0.01),PRKAG2在DF中的表达量显著高于SF(P<0.05);SFRP2和MAPK8在SF中的表达量极显著高于DF(P<0.01);PPP2R2APRSS23虽然在DF和SF的表达量存在倍数关系,但差异并不显著。综上表明,在牛卵泡发育过程中,CPEB1和PRKAG2促进卵泡发育,SFRP2和MAPK8对卵泡的发育可能有抑制作用。

Abstract:

 To study the regulatory mechanism of the relevant genes associated with follicular development,we test the genes expression difference between the dominant follicles (DF) and subordinate follicles (SF) granulose cells of the first follicular wave during estrous cycle in bovine.Bioinformatics methods were used to screen the candidate genes associated with follicular development,and real-time fluorescent quantitative PCR was performed to detect the gene expression pattern between DF and SF granulose cells of the first follicular wave during estrous cycle in bovine.The results showed that 6 candidate genes (SFRP2,CPEB1,PRKAG2,MAPK8,PPP2R2A and PRSS23) related to follicular development were screened.CPEB1 expressed in DF was extremely significantly higher than that in SF (P<0.01),and PRKAG2 mRNA amounts were significantly greater in DF compared with SF (P<0.05).But the expression levels of SFRP2 and MAPK8 were extremely significantly higher in SF than those in DF (P<0.01).CPEB1 and PRKAG2 may play a crucial role to promote the follicular development,however,SFRP2 and MAPK8 may inhibit the follicular development in bovine.
