Dietary copper and not PCB126 caused a significant increase in the serum levels (a) and hepatic expression (b) of ceruloplasmin. Fold change is calculated relative to 6 ppm dietary copper and corn oil treatment. Error bars represent SEM. Each group contained 4–6 animals. * p < 0.05 as compared to adequate (6 ppm) dietary copper. † p < 0.05 as compared to Corn Oil vehicle control.
