Increased serum miR-92a level in patients with hypertension. (A) qPCR analysis of serum miR-92a level in patients with hypertension (HTN) (n = 44) and healthy controls (HC) (n = 21). Cel-miR-39 was used as a spike-in control. The data are fold change normalized to the averaged level of HCs. (B) Brachial–ankle pulse wave velocity (baPWV) of patients and controls. (C, D) Serum NO and ET-1 levels. (E–I) Correlations between serum miR-92a level and baPWV (E), SBP (F), DBP (G) serum ET-1 (H) and NO (I). (J, K) Correlation between baPWV and serum NO (J) and ET-1 (K) levels. Data are mean ± SEM. Normally distributed data were analyzed by the two-tailed Student t test (C, D), and the two-tailed Student t test with Welch correction (B) between 2 indicated groups. Non-normally distributed data were analyzed by the Mann–Whitney U test (A) between 2 indicated groups. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.001. rs Spearman correlation coefficient.
