The study investigated the expression of ANRIL in patients with coronary artery disease and its effect on endothelial dysfunction. The findings suggest that ANRIL is associated with markers of endothelial dysfunction and may regulate HUVEC dysfunction through the TGF-beta R1/Smad signaling pathway. This highlights a potential new therapeutic strategy for preventing endothelial dysfunction in cardiovascular disease.
The long noncoding RNA antisense noncoding RNA in the INK4 locus (ANRIL) plays a critical role in the development of atherosclerosis. However, the precise effect of ANRIL on endothelial dysfunction remains unclear. In this study, we investigated ANRIL expression in patients with coronary artery disease and elucidated the molecular mechanism underlying its effect. ANRIL expression was detected in the blood plasma of 111 patients. We analysed the correlation between ANRIL and endothelial dysfunction markers. We also examined the effect of ANRIL on the regulation of endothelial dysfunction. ANRIL levels were increased in patients with acute coronary syndrome. The expression of ANRIL is associated with the inflammatory cytokines monocyte chemoattractant protein-1 and interleukin-10, which are secreted in response to endothelial dysfunction. Knockdown of ANRIL significantly promoted cell proliferation and tubule formation and inhibited inflammatory activation and apoptosis of human umbilical vein endothelial cells (HUVEC). ANRIL-mediated inhibition of let-7b regulates HUVEC dysfunction by targeting the TGF-beta R1/Smad signalling pathway. This study highlights a new therapeutic strategy for preventing endothelial dysfunction associated with cardiovascular disease.
