Figure 9From: Influence of cell cycle on responses of MCF-7 cells to benzo[a]pyreneExpression of CYP1A1, CYP1B1, AHR, p53, and p21 protein levels in MCF7 cells in different phases of the cell cycle in response to BaP detected by Western blots. Cells were treated with DMSO (0.3%) or BaP (2.5 μM) for 12 h. 15 μg protein was loaded in each lane. β-actin was used as a loading control.Back to article page
