Oxidative stress induced by Cr(VI) in HepG2 cells. (A) Lipid peroxidation relative to the control (100%) in HepG2 cells exposed to different concentrations of Cr(VI) in μM for 24 h. All values are expressed as mean ± S.E.M. (n = 3). *P < 0.05 compared to the control. (B) ROS production in HepG2 cells after treatment with different concentrations of Cr(VI) for 24 h. (C) ROS production in HepG2 cells after treatment with 12.5 μM Cr(VI) for 1 and 2 h respectively. ROS production in cells was measured flow cytometrically by using a cationic fluorescent dye, 2′,7′-dichlorodihydrofluorescein diacetate (H2-DCFDA).
