Methods Cells were maintained in DMEM medium with 10% fetal bovine serum. Five days before the beginning of experiments, the cells were seeded in phenol red-free DMEM medium containing 5% charcoal dextran-treated FBS. The cells were harvested, and seeded in 6-well culture plates or in 75ml flacks. After NP, BisA and DBP treatments for 72h, the cells were harvested, and mRNA and protein expression of PCNA, bcl-2 and bax were detected by reverse transcription-polymerase chain reaction and immunohistochemistry, respectively.
