Taken together, these findings indicated that miR‑31a‑5p is involved in hypertension via the accelerated proliferation of arterial smooth muscle cells and inhibition of apoptosis through targeting TP53.
There was no relationship between atherosclerosis, polymorphism of p53 and the variables accounted: smoking habit (P = 0.72, 0.51 and 0.62 for smokers, non-smokers and former smokers respectively), alcohol consumption (P = 0.17 for individuals with drinking habits and 0.38 for those who do not consume alcohol beverage), systemic arterial hypertension (P = 0.60), diabetes mellitus (P = 0.34), and dyslipidemia (P = 0.89).
Collectively, these findings demonstrate that arterial telomere uncapping and P53/P21-induced senescence are linked to hypertension independently of mean telomere length, and telomere uncapping influences hypertension status more than mean telomere length.
