Data are expressed as means ± SE; n = 5 for all experiments. Cytochrome P-450 (Cyp)1b1+/+ and Cyp1b1−/− mice were infused with vehicle or ANG II for 2 wk and placed in metabolic cages for 24 h before the experiments were completed. The parameters listed above were determined as described in materials and methods.
P < 0.05, vehicle versus the corresponding value from ANG II-infused animals.
