Pancreatic metabolism of benzo(a)pyrene in vitro and in vivo in the Long-Evans rat.
The in vitro metabolism of benzo(a)pyrene was compared between pancreas and liver with and without pretreatment. There was no significant difference in metabolic pathways between the two tissues. Evidence for induction of the metabolism was evident following 3-methyl-cholanthrene pretreatment. Temporal studies demonstrated rapid elimination of BP from the tissues within the first 5 hours with possible recirculation of metabolites 22 hours after injection of the carcinogen. There was significant binding of BP to DNA in pancreas and liver at 5 hours.
