(A) RT-PCR analysis of colon CYP1A1 mRNA expression in ApcMin-exposed mice. The relative expression of CYP1A1 was quantified by densitometric quantitation of CYP1A1 bands and normalized to level of 18 sRNA. The bars represent mean±S.D. for three independent experiments. *P<.005, when 100 μg B(a)P+TC is compared to 50 μg B(a)P+TC; 50 μg B(a)P+USF is compared to 50 μg B(a)P+TC and 50 μg B(a)P+SF; and when 100 μg B(a)P+USF is compared to 100 μg B(a)P+SF groups. (B) Western blot analysis of colon CYP1A1 protein expression in ApcMin-exposed mice. The relative expression of CYP1A1 was quantified by densitometric quantitation of CYP1A1 bands and GAPDH was used as the loading control. The bars represent mean±S.D. for three independent experiments. *P<.005, when 50 μg B(a)P+USF is compared to 50 μg B(a)P+TC; 50 μg B(a)P+SF is compared to 50 μg B(a)P+USF and 50 μg B(a)P+TC; and when 100 μg B(a)P+SF is compared to 100 μg B(a)P+USF and 100 μg B(a)P+TC. (C) Enzyme activity of colon CYP1A1 in ApcMin-exposed mice. The activity of CYP1A1 was determined using luminescence detection. The bars represent mean±S.D. for three independent experiments.
