Resveratrol improves Gly-LDL-induced vascular endothelial cell apoptosis, inflammatory factor secretion and oxidative stress by regulating miR-142-3p and regulating SPRED2-mediated autophagy

Inhibition of SPRED2 reverses the effect of resveratrol on Gly-LDL-induced HUVEC cell proliferation, apoptosis, inflammatory factor secretion and oxidative stress.
