Benzo[a]pyrene-induced cell cycle arrest in HepG2 cells is associated with delayed induction of mitotic instability Vrije Universiteit Brussel
The environmental carcinogen benzo[a]pyrene (B[a]P) after being metabolised by cytochrome P450 enzymes forms DNA adducts. This abnormal situation induces changes in the cell cycle, DNA damage, chromosomal and mitotic aberrations, all of which may be related to carcinogenesis. In order to further investigate the mechanistic basis of these effects, HepG2 cells were treated with 3 ?M B[a]P for various time periods, followed by further incubation in ...
