升高的C3a和瘤坏死因子-α (TNF-α) 蛋白和TNF-α mRNA表明在复发性自发性流产 (RSA) 中存在免疫失调. 这些标记可能有助于早期识别无法解释的RSA的风险.
科学领域:
- 免疫学 免疫学 免疫学
- 生殖医学 生殖医学
- 生物标志物发现发现
背景情况:
- 经常性自发流产 (RSA) 影响了许多怀孕,许多病例仍然无法解释.
- 孕产妇的免疫失调越来越多地与无法解释的RSA有关.
- 早期识别分子和免疫因素对于管理RSA至关重要.
研究的目的:
- 研究补充成分C3a和瘤坏死因子-α (TNF-α) 作为复发性自发性流产 (RSA) 的潜在生物标志物.
- 评估血清C3a和TNF-α蛋白水平的诊断准确性,以及TNF-αmRNA表达,在患有RSA的女性中.
主要方法:
- 在75名女性 (42名RSA,33名对照) 中,使用酶相关免疫吸收试验 (ELISA) 量化血清C3a和TNF-α蛋白水平.
- 分析了TNF-α和C3的全血mRNA表达,使用逆转录定量聚合酶链反应 (RT-qPCR).
- 进行了接收器操作特征 (ROC) 曲线分析,以评估诊断准确性.
主要成果:
- 与对照组相比,RSA组的血清C3a和TNF-α蛋白度显著更高 (分别为p=0.004和p=0.016).
- 在RSA患者中,TNF-α mRNA表达显著增加 (p=0.0003),而C3 mRNA没有显著差异.
- 与血清C3a和TNF-α蛋白相比,TNF-α mRNA表达显示出更高的诊断准确性 (AUC=0.776).
结论:
- 血清C3a和TNF-α,特别是TNF-αmRNA的升高,显示出可能成为复发性自发性流产 (RSA) 的生物标志物.
- 这些发现支持RSA病变发生过程中免疫失调的作用.
- 蛋白质和基因表达的综合分析可能会提高RSA的早期风险分层.

What is Gene Expression?
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
