| Summary: | Objective This study explored miRNA-126 and HIF-1α levels in patients with OSAHS-related hypertension. To analyze the relationship between miRNA-126 and OSAHS-related hypertension and explore the pathogenic mechanisms of miRNA-126 and the HIF-1α pathway.Materials and Methods The 120 participants were assigned to four groups based on their apnea-hypopnea index (AHI) and the presence of hypertension: healthy control group, hypertension group, non-hypertensive OSAHS group, and OSAHS-related hypertension group, with 30 objects in each group. All subjects underwent overnight sleep monitoring and 24-hour (h) ambulatory blood pressure. Their blood samples were analyzed for the following parameters: triglycerides (TG), fasting blood glucose (GLU), total cholesterol (TC), HDL, uric acid (UA), and LDL, hypoxia-inducible factor-1 alpha (HIF-1α), VEGF, C-reactive protein (CRP), IL-6 and tumor necrosis factor alpha (TNF-α). The relative expression levels of miRNA-126 were assessed by RT-qPCR and Western blotting, and dual-luciferase reporter assays were conducted to verify the association between miR-126-3p and HIF1-α.Results Results indicated that HIF-1α is a target gene of miRNA-126 and is negatively regulated by miRNA-126; Levels of miRNA-126 were significantly lower in OSAHS and hypertension patients relative to healthy controls, with the lowest levels observed in the OSAHS-related hypertension group(p < .05). miRNA-126 levels were negatively correlated with HIF-1α, VEGF, TNF-α, CRP, IL-6, TG, TC, LDL, GLU and UA levels (p < .01), while it showed positive correlation with HDL level (p < .01).Conclusion The level of miRNA-126 in patients with OSAHS-related hypertension is lower than that in patients with OSAHS alone and those with hypertension alone. |
