Peculiarities of placental microRNA expression in pregnancies complicated by gestational diabetes mellitus and preeclampsia
The aim of study was to determine feasible changes of placental miRNAs expression profiles revealed by next generation sequencing (NGS) in pregnancies with GDM complicated or not with PE. Out of 27 miRNAs, studied expression was significantly different (FDR < 0.05) only for his-miR-45a. Comparative analysis of revealed reliable differences in expression of hsa-miR-4532 (p < 0.0001, FDR = 0.0008), hsa-miR-34c-5p (p < 0.0001, FDR = 0.0083), and hsa-miR-193b-5p (p < 0.0001, FDR = 0.0139) in pregnancy complicated by PE, without of GDM. The present results suggest that GDM and PE are associated with specific alterations in the placental miRNA expression profiles. Further studies are needed to verify the role of these microRNA in molecular mechanisms underlying GDM and PE pathogenesis.
