Sulforaphane protects human umbilical vein endothelial cells from oxidative stress via the miR-34a/SIRT1 axis by upregulating nuclear factor erythroid-2-related factor 2.

ABSTRACT: Oxidative stress-induced vascular endothelial cell dysfunction serves an essential role in the initiation and development of atherosclerosis. Sulforaphane (SFN), a naturally occurring antioxidant, has previously demonstrated to exert protective effects on the endothelium against oxidative stress. However, further studies are required to determine its underlying molecular mechanism prior to clinical application. Accumulating evidence suggests that alterations in the microRNA (miRNA/miR)-34a/sirtuin-1 (SIRT1) axis occur with oxidative stress. Therefore, the present study aimed to investigate if SFN exerts a protective role against oxidative stress in vascular endothelial cells through regulation of the miR-34a/SIRT1 axis. Human umbilical vein endothelial cells (HUVECs) were treated with H
