摘要
旨在利用蛋白质组学技术探究伊犁马妊娠早期血清蛋白质组特征,筛选差异蛋白质并分析其在妊娠中的作用。本研究选取年龄相同、膘情相近的健康伊犁马母马20匹,自然发情后进行人工授精。在母马排卵后第13天进行妊娠诊断,根据B超结果选择妊娠母马与未妊娠母马各3匹并采集其血清样品。利用4D-DIA技术对伊犁马母马血清样品进行蛋白定量定性分析,筛选差异蛋白质并进行GO、KEGG等生物信息学分析。结果显示,共鉴定出823个蛋白质,分子量范围在8~1010 ku;根据差异倍数绝对值大于1.5倍、P<0.05的阈值,筛选出53种差异显著性蛋白质,其中26个蛋白上调,27个蛋白下调。差异蛋白质主要参与细胞代谢、生物调节、代谢、对刺激的反应、细胞成分组织或生物发生等生物学过程;KEGG富集通路包含蛋白酶体、精氨酸生物合成、PI3K-Akt信号、ECM受体相互作用等与妊娠相关通路。根据GO、KEGG等生物学分析,初步筛选出6种差异显著性蛋白可能与早期妊娠存在关系,并用其绘制蛋白互作网络图,结果显示,CTSS、MMP1、SERPINA5等处在关键节点。研究初步筛选出6种妊娠差异蛋白,为今后筛选马属动物妊娠特异性蛋白及分子调控机制提供了基础资料。
The purpose of this article was to explore the serum proteomic characteristics of early pregnancy in Yili horses using proteomic techniques,screen for differential proteins,and analyze their roles in pregnancy.In this study,20 healthy Yili mares with the same age and similar weight were selected for artificial insemination after natural estrus.Pregnancy diagnosis was performed on the 13th day after ovulation in the mare.Three pregnant mares and three non pregnant mares were selected based on ultrasound results,and their serum samples were collected.Using 4D-DIA technology for protein quantitative and qualitative analysis of serum samples from Yili mares,screening differential proteins,and conducting bioinformatics analysis such as GO and KEGG.The results showed that a total of 823 proteins were identified,with a molecular weight range of 8-1010 ku;Based on the threshold of absolute multiple of differences greater than 1.5 times and P<0.05,53 proteins with significant differences were screened,of which 26 proteins were upregulated and 27 proteins were downregulated.Differential proteins mainly participated in biological processes such as cellular metabolism,biological regulation,metabolism,response to stimuli,cellular component organization,or biogenesis;The KEGG enrichment pathways included proteasomes,arginine biosynthesis,PI3K Akt signaling,ECM receptor interactions,and other pregnancy related pathways.Based on biological analysis such as GO and KEGG,six significantly different proteins were preliminarily screened for possible relationship with early pregnancy,and protein interaction network diagrams were drawn using them.The results showed that CTSS,MMP1,SERPINA5,and others were at key nodes.Six pregnancy specific proteins have been preliminarily screened in this study,providing basic data for screening pregnancy specific proteins and molecular regulatory mechanisms in equine animals in the future.
