Abstract

Objectives: How chronic pelvic inflammatory disease (CPID), the most common cause of infertility, affects metabolic profiles of follicular fluid (FF) remains unknown. This study aimed to identify candidate biomarkers in FF of infertile women with CPID.

Method: FF samples were collected from infertile women with CPID (n = 8) and healthy controls (n = 8) at the time of oocyte retrieval. Untargeted metabolomic profiling of FF samples was conducted using the liquid chromatography-tandem mass spectrometry (LC-MS/MS).

Results: A total of 240 differential metabolites (104 named biochemicals and 136 unnamed biochemicals) were screened out and identified. Among them, pregnane-3,3-diol, pc(p-18:1(11z)/18:3(6z,9z,12z)), and 1-octadecanoyl-2-(4z,7z,10z,13z,16z,19z-docosahexaenoyl)-sn-glycero-3-phosphoethanolamine were markedly down-regulated, while 17,21-dihydroxypregnenolone was significantly up-regulated in infertile women with CPID. Furthermore, KEGG biological pathway analysis revealed that these metabolites were especially enriched in steroid hormone biosynthesis, glyoxylate and dicarboxylate metabolism, glucagon signaling pathway, and the tricarboxylic acid (TCA) cycle.

Conclusion: FF of infertile women with CPID showed unique metabolic changes that may be involved in the pathogenesis of infertility and serve as new therapeutic targets or diagnostic biomarkers.

基于LC-MS/ ms的代谢组学分析确定慢性盆腔炎不孕妇女卵泡液中的候选生物标志物。

目的:慢性盆腔炎(CPID)，最常见的不孕原因，如何影响卵泡液(FF)的代谢谱仍然未知。本研究旨在确定CPID不孕妇女FF中的候选生物标志物。方法:取卵时分别采集CPID不孕妇女(n = 8)和健康对照(n = 8)的FF样本。采用液相色谱-串联质谱(LC-MS/MS)对FF样品进行非靶向代谢组学分析。结果:共筛选鉴定出240种差异代谢物(已命名生化物质104种，未命名生化物质136种)。其中，妊娠烷-3,3-二醇、pc(p-18:1(11z)/18:3(6z,9z,12z))和1-十八烷醇-2-(4z,7z,10z,13z,16z,19z-二十二碳六烯基)- cn -甘油-3-磷酸乙醇胺显著下调，17,21-二羟基孕烯醇酮显著上调。此外，KEGG生物通路分析显示，这些代谢物尤其富集于类固醇激素生物合成、乙醛酸盐和二羧酸盐代谢、胰高血糖素信号通路和三羧酸(TCA)循环。结论:CPID不孕妇女的FF表现出独特的代谢变化，可能参与了不孕的发病机制，可作为新的治疗靶点或诊断生物标志物。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
