benzotriphenylene

05/01/1983 - "The tumor-initiating activities of dibenz[a,c]anthracene (DBA) and of the related trans-1,2-, 3,4- and 10,11-dihydrodiols have been examined on mouse skin subsequently promoted with 12-O-tetradecanoyl-phorbol-13-acetate (TPA). "
02/01/1998 - "Dermal and epidermal EROD specific activities in microsomal samples prepared from both tumor-bearing and non-tumor-bearing mice were elevated 9- to 14- and 43- to 77-fold, respectively, above constitutive levels 16-20 h after a single topical application of 100 nmol of dibenz[a,c]anthracene (DB[a,c]A). "
12/15/1983 - "Dibenz[a,c]anthracene proved to be a relatively weak carcinogen, producing less than 3% tumor incidence at doses up to 300 micrograms per mouse. "
01/01/1980 - "The bromo-compound is also a powerful promoter of tumors initiated in mouse skin with 7,12-dimethylbenz(a)anthracene, whereas dibenz-(a,c)anthracene is inactive as a promoter. "
03/01/1978 - "Dibenz[a,c]anthracene: a potent inhibitor of skin-tumor initiation by 7,12-dimethylbenz[a]anthracene."

03/01/1993 - "Treatment of murine hepatoma 1c1c7 cultures with dibenz[a,c]anthracene (DB[a,c]A)-induced P450 Cyp1a-1, as indicated by analyses of CYP1A1 mRNA and 7-ethoxyresorufin O-deethylase (EROD) activity. "

12/15/1983 - "The relationship between the Ah locus and the induction of subcutaneous fibrosarcomas by dibenz[a,h]anthracene and dibenz[a,c]anthracene was investigated in C57BL/6J (Ahb/Ahb), (C57BL/6J)(DBA/2J)F1 (Ahb/Ahd) and (Ahd/Ahd) mice. "
