The Protective Effects of Isoliquiritigenin and Glycyrrhetinic Acid against Triptolide-Induced Oxidative Stress in HepG2 Cells Involve Nrf2 Activation

Figure 3

Cells were exposed to 50 nM TP for 24 h after incubation with various concentrations of ISL and GA for 12 h and 24 h, respectively. (a) The content of ROS was measured and normalized to control group. (b) The content of intracellular GSH was measured and normalized to protein content (). versus control, versus control; versus TP group, versus TP group. Control (Column 1): 0.1% DMSO.
