Benzo(a)pyrene 5-8 cytochrome P450, family 1, subfamily b, polypeptide 1 Mus musculus 160-166 23761301-6 2013 BaP-metabolizing CYP1B1 in the PSI and CYP3A59 in the PGD are the most likely candidates to participate in tumor initiation in the epithelial cells of these two tissues; oncogenes and tumor-suppressor genes upregulated and downregulated during tumorigenesis are completely different between these tissues. Benzo(a)pyrene 0-3 cytochrome P450, family 1, subfamily b, polypeptide 1 Mus musculus 17-23 19666105-5 2009 In addition, the BaP-induced CYP1A1 and 1B1 protein levels and BaP-elevated glutathione S-transferase (GST) activity were significantly higher in these transgenic cells, in parallel with elevated GSTp1, CYP1A1, and CYP1B1 mRNA levels, compared to wild-type MAECs.

Benzo(a)pyrene 56-70 cytochrome P450, family 1, subfamily b, polypeptide 1 Mus musculus 24-30 17049425-7 2006 There was a significant basal expression of Cyp1b1 in the liver of all genotypes, and this expression was independent of the BP exposure.

Benzo(a)pyrene 65-68 cytochrome P450, family 1, subfamily b, polypeptide 1 Mus musculus 0-19 16307768-10 2006 Although TNFalpha and CYP1B1 are implicated as essential mediators of hypocellularity, the similar induction of TNFalpha mRNA and CYP1B1 mRNA in the BM by BP and DMBA suggests that they are not limiting factors in mediating the different effects of these PAHs. Benzo(a)pyrene 155-157 cytochrome P450, family 1, subfamily b, polypeptide 1 Mus musculus 130-136 16377763-0 2006 Oral benzo[a]pyrene in Cyp1 knockout mouse lines: CYP1A1 important in detoxication, CYP1B1 metabolism required for immune damage independent of total-body burden and clearance rate.

Benzo(a)pyrene 97-111 cytochrome P450, family 1, subfamily b, polypeptide 1 Mus musculus 11-17 16377763-8 2006 Thus, a balance between tissue-specific expression of the CYP1A1 and CYP1B1 enzymes governs sensitivity of benzo[a]pyrene toxicity and, possibly, carcinogenicity.

Benzo(a)pyrene 60-62 cytochrome P450, family 1, subfamily b, polypeptide 1 Mus musculus 0-6 14613719-0 2003 Bone marrow cytotoxicity of benzo[a]pyrene is dependent on CYP1B1 but is diminished by Ah receptor-mediated induction of CYP1A1 in liver. Benzo(a)pyrene 28-42 cytochrome P450, family 1, subfamily b, polypeptide 1 Mus musculus 59-65 14613719-2 2003 Benzo(a)pyrene (BP), a much more potent Ah receptor ligand, shows very different responses that nevertheless depend on CYP1B1. Benzo(a)pyrene 0-14 cytochrome P450, family 1, subfamily b, polypeptide 1 Mus musculus 119-125 14613719-2 2003 Benzo(a)pyrene (BP), a much more potent Ah receptor ligand, shows very different responses that nevertheless depend on CYP1B1. Benzo(a)pyrene 16-18 cytochrome P450, family 1, subfamily b, polypeptide 1 Mus musculus 119-125 14613719-9 2003 Thus, hepatic metabolism may prevent BP from reaching the BM, where it can be bioactivated by CYP1B1.

Benzo(a)pyrene 30-44 cytochrome P450, family 1, subfamily b, polypeptide 1 Mus musculus 8-26 12649394-8 2003 BP treatment of SMCs resulted in induction of aryl hydrocarbon hydroxylase (AHH) activity and CYP1B1, but not CYP1A1, apoprotein. Benzo(a)pyrene 0-2 cytochrome P450, family 1, subfamily b, polypeptide 1 Mus musculus 94-100 12649394-10 2003 In conclusion, the results of this study support the hypothesis that in SMCs, which are target sites for the development of atherosclerosis, the major bioactivation pathway of BP entails CYP1B1-mediated formation of the 3-OH-BP and BPQ, which are proximate genotoxic metabolites that may in turn get transformed to ultimate DNA-binding metabolites, which may contribute to atherogenesis by PAHs.
