AbstractMicroRNAs 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.Copyright © 2021 the Author(s).
