FIG. 1.
Mouse strains and experimental designs. The B6 and B6.D2 mouse strains possess the high- and low-affinity Ahr genes, respectively (A). Two different BaP exposure protocols were followed. Protocol 1, short-term BaP exposure: Mice were exposed to 10 mg/kg/day BaP by gavage 5 days/week for 10 weeks (B). Protocol 2, long-term BaP exposure: Mice were exposed to BaP ad libitum in corn oil–soaked Western chow (BaP dissolved at 800 mg/ml in corn oil) at an estimated dose equivalent of 10 mg/kg/day for 23 weeks (C). The experimental design for the microarray experiments (D).
