Figure 5

Western blot of NQO1, HO-1 and SOD1 proteins in WT and N0 cells treated with PB (5 and 10 μg/ml). The blots shown are examples of three separate experiments (A) from 20 μg cytosolic proteins and relative intensities over β-actin for NQO1 (B), HO-1 (C) and SOD1 (D) protein expression after 24 h treatment of PB. SFN treatment at 5 μM was used as positive control. Data represent ± S.E.M from three independent experiments. ^a P < 0.05, compared to control WT cells; ^b P < 0.05, compared to respective WT cells group.
