Objective: To investigate the protective effects of estrogen on the mitochondria in human umbilical vascular endothelial cells (HUVECs).
Methods: HUVECs were exposed to H2O2 at 250 micromol/L for 4 h with or without pretreatment with 17-estradiol (E2) and ICI182780. Complex IV activity of the cells was measured with chromometry, and 2, 7-dichlorofluorescein diacetate (DCFH-DA) was used to determine intracellular reactive oxygen species (ROS).
