Atherosclerosis (As) is a common disease, which is serious hazard to human health. As the main pathological basis of ischemic cardiac and cerebral vascular disease, including coronary heart disease, cerebrovascular disease, and thromboembolic disease, it is a chronic inflammatory lesion of the arterial vessel wall. So far the pathogenesis of As has not been fully understood. Therefore, it is still lack of effective clinical prevention and treatment of drugs. More and more evidence indicate that miRNA plays an important role in the pathophysiology of many diseases, especially the occurrence and development of cardiovascular diseases. MiRNAs are widely detected in human coronary artery endothelial cells, which might participate in diverse biological functions through targeting different As associated genes. The aim of this study was to investigate the molecular mechanisms underlying miR-30s roles in As. Our study found the high expression of miR-30b and miR-30e in As clinical samples, identified the regulatory relationship of miR-30b and miR-30e to ITGA4 and PLCG1, respectively, and initially explored the effects of miR-30b and miR-30e on cell cycle and apoptosis through targeting ITGA4 and PLCG1. These data may provide a theoretical basis for clarifying the mechanism of miR-30s in As.
