摘要:

旨在从牛发情周期第一卵泡波中最大卵泡ODF1(The largest follicle at onset of deviation)和第二大卵泡ODF2(The second largest follicle at onset of deviation)转录组水平上筛选卵泡发育差异表达基因。采集牛发情周期第一卵泡波ODF1和ODF2,分别分离颗粒细胞并提取总RNA,构建RNA文库,通过Illumina平台对ODF1和ODF2测序;筛选出ODF1与ODF2两个转录本之间比值大于2的差异表达基因,并采用qRT-PCR对筛选出的基因在牛发情周期内第一卵泡波优势卵泡(Dominant follicles,DF)和从属卵泡(Subordinate follicles,SF)颗粒细胞中功能验证。共获得8个卵泡发育差异表达基因,其中7个基因筛选自ODF1/ODF2(BEX2、UBN1、SIK1、SPARCL1、LOC784256、LOC789231和LOC785462),1个筛选自ODF2/ODF1(SAFB2);qRT-PCR结果表明,BEX2、UBN1、LOC784256和LOC789231在DF中mRNA表达量极显著高于SF(P<0.01),SAFB2在SF中mRNA表达量极显著高于DF(P<0.01),SIK1和SPARCL1在SF中mRNA表达量显著高于DF(P<0.05),虽然LOC785462在SF中mRNA表达量高于DF,但差异不显著(P>0.05)。qRT-PCR检测BEX2、UBN1、LOC784256、LOC789231和SAFB2的结果与高通量测序中该基因在ODF1和ODF2的RPKM的差异趋势基本一致,而SIK1、SPARCL1和LOC785462不一致。

Abstract:

This study was performed to screen genes associated with follicular development from ODF1(The largest follicle at onset of deviation)and ODF2(The second largest follicle at onset of deviation)in transcript levels of bovine.The largest and second largest follicle were collected from onset of deviation then separated granulosa cells from which extracted total RNA.High-throughput deep sequencing was carried out by sequencing platform of Illumina.According to the results of assessment analysis in significant enrichment analysis of Gene Ontology function and differential expression in gene screening.Further,screening differential expression gene by ODF1/ODF2 or ODF2/ODF1>2 as the candidate genes.By real-time fluorescent quantitative PCR(qRT-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.Eight candidate genes related to follicular development were screened and 7 genes(BEX2,UBN1,SIK1,SPARCL1,LOC784256,LOC789231,LOC785462)from ODF1/ODF2 and one (SAFB2)from ODF2/ODF1,BEX2,UBN1,LOC784256,LOC789231 expressed in DF was extremely significantly higher than that in SF(P<0.01).But the expression levels of SAFB2 was extremely significantly higher in SF than those in DF(P<0.01) and SIK1,SPARCL1 were significantly greater in SF compared with DF(P<0.05).This indifferences trends was consistent between qRT-PCR test results of BEX2,UBN1,LOC784256,LOC789231,SAFB2 and high-throughput sequencing results of RPKM in ODF1 and ODF2.The qRT-PCR test results of SIK1,SPARCL1 and LOC785462 was opposite with the high-throughput sequencing of the gene RPKM in ODF1 and ODF2.
