PCB2 protected HUVECs from ox-LDL-induced oxidative stress. (A-C) HUVECs were stimulated with ox-LDL (100 µg/ml) for 24 h and then treated with different concentrations of PCB2 (0, 0.5, 1, or 2 µg/ml) for an additional 12 h. Next, MDA, ROS, and MMP levels were measured by corresponding kits. n = 3 independent biological replicates in A-C. ***P < 0.001, #P < 0.05, ##P < 0.01, ###P < 0.001
