The aim of our study was to examine the expression of miR-17, miR-29a and miR-181a, as well as TNF-α, IL-1β, IL-6 and IL-17 in women with GH and to investigate possible correlations between these parameters. Study design: The study included 64 pregnant women, placed either in the control or the GH group. Quantitative real-time PCR (qPCR) was used to determine expression levels of microRNAs and cytokines’ mRNAs. Main outcome measures: Expression levels of miRNAs (miR-17, miR-29a and miR-181a) and proinflammatory cytokines mRNAs (TNF-α, IL-1β, IL-6 and IL-17) in women with gestational hypertension were compared to the control group (healthy pregnant women). Results: No significant changes in microRNAs expression level were found between compared groups. TNF-α was significantly upregulated in the GH group compared to controls. Expression levels of other investigated cytokines did not differ between examined groups. ROC curve analysis indicated that TNF-α does not show sufficient ability to discriminate between CG and GH patients. TNF-α was significantly positively correlated with IL-1β and IL-17 and negatively correlated with miR-181a. Conclusions: Our results point to the involvement of proinflamatory cytokines in gestational hypertension. Although increased expression of TNF-α was found in the GH group, this cytokine did not show sufficient ability to discriminate between GH and healthy pregnancies. © 2024 Elsevier B.V.BiomarkerGestational hypertensionmicroRNAProinflamatory cytokineTNF-αExpression analysis of microRNAs and cytokine mRNAs in pregnancies complicated by gestational hypertension
