MicroRNAs play important roles in gestational diabetes mellitus (GDM), and this study aimed to elucidate the clinical significance of miR-96-5p in diagnosing GDM.There are 123 pregnant women diagnosed with GDM and 123 healthy pregnant women were enrolled as control participants. Placenta and plasma samples from the patients and control participants were collected, and quantitative reverse transcription polymerase chain reaction (RT-qPCR) was performed to determine miR-96-5p expression levels. Moreover, a receiver operating characteristic (ROC) curve was established to evaluate the significance of miR-96-5p in diagnosing GDM. HRT-8/SVneo trophoblasts were cultured under high glucose conditions and treated with miR-96-5p mimics, and cell viability was examined.miR-96-5p levels were significantly decreased in both the placenta and plasma samples of patients with GDM. The ROC curve indicated that miR-96-5p can serve as a diagnostic biomarker for GDM with high sensitivity and specificity. Moreover, miR-96-5p levels were markedly low under high glucose conditions, and the overexpression of miR-96-5p increased the viability, respectively, of trophoblasts in vitro.miR-96-5p may participate in the pathogenesis of GDM by exerting effects on the viability of trophoblasts.
微小 RNA 在妊娠糖尿病 (GDM) 中发挥重要作用,本研究旨在阐明 miR-96-5p 在诊断 GDM 中的临床意义。共有 123 例确诊为 GDM 的孕妇和 123 例健康孕妇作为对照组参与本研究。收集患者和对照组的胎盘和血浆样本,并进行定量逆转录聚合酶链反应 (RT-qPCR) 以确定 miR-96-5p 的表达水平。此外,还建立了受试者工作特征 (ROC) 曲线来评估 miR-96-5p 在诊断 GDM 中的意义。在高糖条件下培养 HRT-8/SVneo 滋养细胞,并给予 miR-96-5p 模拟物处理,检测细胞活力。结果显示,GDM 患者的胎盘和血浆样本中 miR-96-5p 水平均显著降低。ROC 曲线表明 miR-96-5p 可作为 GDM 的诊断生物标志物,具有较高的灵敏度和特异性。此外,在高糖条件下 miR-96-5p 水平明显降低,而过表达 miR-96-5p 则分别增加了体外滋养细胞的活力。miR-96-5p 可能通过对滋养细胞活力的影响参与 GDM 的发病机制。
