Type 2 diabetes mellitus (T2DM) is the most common metabolic disease. High glucose-induced macrovascular disease and microangiopathy are major complications of diabetes. E2F3, a member of the E2F transcription factor family, is closely related to cardiovascular diseases. Resveratrol, a nonflavonoid polyphenolic compound widely found in plants, has been shown to have cardiovascular protection. However, there are few studies on whether resveratrol can effectively treat diabetic angiopathy, and the specific mechanism involved needs further study. This study investigated whether E2F3 transcription factors are involved in the process of vascular endothelial injury induced by high glucose and observed its effects on the proliferation of vascular endothelial cells. Then, it analyzed whether resveratrol can inhibit high glucose-induced vascular endothelial cell injury by regulating the E2F3 pathway. We demonstrated that the expression level of the E2F3 transcription factor was significantly inhibited in high glucose state. Resveratrol inhibited high glucose-induced vascular endothelial cell injury by upregulating the E2F3 pathway. High glucose can induce vascular endothelial injury by inhibiting E2F3 gene expression, while resveratrol can inhibit high glucose-induced vascular endothelial injury by activating the E2F3 pathway.

Abstract Objective: To investigate the role of microRNA-155-5p (miR-155-5p) on apoptosis and inflammatory response in human glomerular endothelial cells (HRGEC) cultured with high glucose.Methods: The primary human glomerular endothelial cells (HRGEC) were studied, QPCR, WB , IF were used to detect cell morphology, target gene ETS-1 (ETS-1), downstream factors VCAM-1 and MCP-1, and apoptosis of cells in each group after high glucose stimulation and transfection with miR-155 overexpression or inhibitor.Results:1.The expression of inflammatory factors and apoptosis of HRGEC cells increased under high glucose stimulation.2.The overexpression of miR-155 in HRGEC cells under high glucose stimulation decreased the expression of ETS-1, while the expression of ETS-1 increased when miR-155 was inhibited. These results suggest that miR-155 may be involved in endothelial cell injury by negatively regulating the expression of ETS-1.3.HRGEC cells were transfected with miR-155 mimic and ETS-1 siRNA with high glucose stimulation. The expression of ETS-1 was positively correlated with the expression of downstream factors VCAM-1 and MCP-1. These results suggest that ETS-1 can mediate endothelial cell inflammation by regulating VCAM-1 and MCP-1.
