Expression of angiotensin (A) AT1 (AT1R) and (B) AT2 receptors (AT2R) in the kidney cortex of lean and prehypertensive obese Zucker rats after 2 weeks treatment with vehicle (Veh), AT2R antagonist PD123319 (PD), AT2R agonist (C21) and both PD123319+C21 (PD+C21). The upper panels show representative western blots for AT1R, AT2R and β-actin. Lower panels represent quantitative results normalized to β-actin. Data are mean ± SEM. * indicates p<0.05 vs lean vehicle treated rats (n=5-6).
