Figure 4From: Aryl hydrocarbon receptor-dependent upregulation of Cyp1b1 by TCDD and diesel exhaust particles in rat brain microvesselsCyp1a1 protein expression in brain microvessels of TCDD-treated rats. Rats were dosed with a single dose of TCDD (25 μg/kg i.p.) and brain microvessels were isolated after 72 h for Cyp1a1 analysis by Western blotting; rat Cyp1a1 supersomes were used as positive control for Cyp1a1 expression.Back to article page
