1 We investigated the hepatic expression of CYP1 and AhR following oral administration of DMBA (100 mg/kg b.w.) 6,11-dimethylbenzo(b)naphtho(2,3-d)thiophene cytochrome P450, family 1, subfamily b, polypeptide 1 Rattus norvegicus
2 Because DMBA oxidation produces a highly mutagenic metabolite and is finally catalyzed by CYP1B1, a relatively low PCB126 dose might produce the biological character to potentially increase the risk of DMBA-induced mammary carcinoma. 6,11-dimethylbenzo(b)naphtho(2,3-d)thiophene cytochrome P450, family 1, subfamily b, polypeptide 1 Rattus norvegicus
