CircNMD3 relieves endothelial cell injury induced by oxidatively modified low-density lipoprotein through regulating miR-498/ BMP and activin membrane-bound inhibitor (BAMBI) axis.

ABSTRACT: Atherosclerosis (AS) is one of the most common vascular diseases. The endothelial injury theory indicates that atherosclerotic plaque is the result of endothelial cell injury. Recent studies have revealed that circRNAs are abnormally expressed in AS cell models, which are implicated in the regulation of various cell behaviors. In this study, we showed the downregulation of circNMD3 in AS, and studied its role in the model of endothelial cell injury by proliferation and apoptosis assay, caspase 3 activity assay, and ELISA. We also identified and validated its downstream targets by luciferase reporter assay, RNA pull-down experiment, Western blot, and RT-qPCR. CircNMD3 overexpression or miR-498 knockdown could inhibit the ox-LDL (oxidatively modified low-density lipoprotein)-induced injury i
