A Potential Risk Factor of Essential Hypertension in Case-control Study: MicroRNAs MiR-10a-5p

: Essential hypertension is a multifactorial disease with high morbidity. The researches on the influence of genes on the disease are still in its infancy, and the mechanism of gene regulation is not clear. MiRNAs are key molecules that regulate the expression control of protein-coding or protein-non-coding RNA. It may be an important biological molecule risk factor for essential hypertension.: A case-control study with 98 EH and 98 non-EH was conducted in our experiment. The candidate miRNAs including miR-10a-5p and miR-497-5p were detected and verified by qRT-PCR.: The expression level of miRNA in EH cases was significantly lower than the healthy control ( = 0.005). In addition, the relative expression of miR-10a-5p was closely positive correlated with DBP ( = 0.162, = 0.023) and SBP ( = 0.223, = 0.002). After adjusting confound factors, the result of the logistic regression indicated that hypo-expression of miR-10a-5p is a risk factor for EH (OR(95%CI) = 1.676(1.302,2.157), adjusted < 0.0001). And the ROC analysis shows that the combined line with BMI and miR-10a-5p was a values marker for EH (AUC: 0.728, < 0.0001).: Lower expression of miR-10a-5p, as the key role, is significantly related to the risk of EH and maybe as a potential biomolecule for EH.
