INTRODUCTION: Placenta accreta spectrum (PAS) disorders pose a grave threat to maternal life due to severe hemorrhage and the heightened risk of peripartum hysterectomy. Consequently, there's a pressing need for circulating biomarkers in clinical settings. MicroRNAs (miRNAs), being stable in peripheral circulation, hold promise as potential biomarkers for PAS.
METHODS: This study recruited singleton live pregnancies, including cases of invasive PAS, placenta previa (PP), and controls, across three phases. Initially, RNA-seq of peripheral blood identified 6 miRNAs in the screening phase. Subsequently, in the training and validation phases, miR-23a-5p, along with its target genes ASF1B and CHTF8, were validated using qRT-PCR. The diagnostic value of these markers for PAS and adverse outcomes was evaluated using Receiver Operating Characteristic (ROC) curves.
RESULTS: The results showed miR-23a-5p was down-regulated in PAS, whereas ASF1B and CHTF8 were up-regulated. miR-23a-5p had modest diagnostic efficiency for PAS and adverse outcomes, as the AUC were 0.689 and 0.711 respectively. However, when miR-23a-5p combined with CHTF8, the AUC can improve greatly to 0.869 in PAS diagnosis and 0.856 in prediction of adverse outcomes.
DISCUSSION: We propose the miR-23a-5p plays a role in PAS pathogenesis through regulating cell proliferation, migration, invasion, apoptosis by targeting various genes. This study confirmed its potential value of miR-23a-5p combined with target gene CHTF8 as novel biomarkers for PAS and adverse outcomes.
