Differential regulation of Cyp1a1 and Cyp1b1 in DMBA-induced rat mammary adjacent tissues and tumors. Bars represent means ± SEM of quantitation (fold change of control) of (a) Cyp1a1 and (b) Cyp1b1 mRNA corrected for Gapdh mRNA as internal standard in control and DMBA-induced adjacent mammary tissues and tumors from 8 animals/group (n = 8). Different letters represent statistical differences (P < 0.05)
