Altered antioxidant enzyme gene expression and GSH level in HepG2 cells treated with TBH is restored in presence of Geraniin. (A) Intracellular GSH level was determined in terms of nmol GSH/mg protein. (B) CAT (C) GPx and (D) SOD gene expression was measured in HepG2 cells pretreated with geraniin (0, 1, 10, and 25 μM) for 2 hrs and exposed to TBH (2 mM) for 3 hrs. Data shown represent the mean values of three experiments ± SE. *P < 0.05 vs. control. **P < 0.05 vs. TBH (2 mM).
