mRNA and protein expression of CYP enzymes, AOEs and cytokine IL-1β (A-C). (A) mRNA expression was analyzed in SVG cells (at 24, 48, and 72 h) treated with 1 μM concentration of BaP (daily treatment). (B) Representative western blots of IL-1β, AOEs (SOD1 and CAT), and CYP enzymes (CYP2A6, CYP1B1, CYP1A1) in SVG cells (Western blot at 24, 48, and 72 h) treated with 1 μM concentration of BaP (daily treatment). Untreated controls were considered as 100% in the densitometry analysis. (C) Densitometry analysis. Statistical analyses were carried out by using Student’s t-test. Results are expressed as means ± S.E.M of n = 4 experiments. **P ≤0.01, ***P ≤0.001 in comparison with untreated control.
