Figure 6. Effect of harmaline and harmalol on BaP-mediated induction of CYP1A1 catalytic activity in HepG2 cells.

Figure 6

Cells were incubated with increasing concentrations of harmaline (A) or harmalol (B) in the absence and presence of BaP (1 µM) for 24 h. The amount of CYP1A1 activity was determined using CYP1A1-dependent EROD assay. Resveratrol (Res, 12.5 µM) was used as a positive control. Values represent mean activity ± S.E.M. (n = 8). (+) P < 0.05 compared with control (C), (*) P < 0.05 compared with BaP.
