(A) β2-adrenergic receptor density in the myocardium. NT, nontransgenic littermates (n = 8); CAM vehicle, vehicle-treated CAM β2-adrenergic receptor transgenic animals (n = 12); CAM ICI, ICI 118,551-treated transgenic animals (n = 8). Shown are means ± SEM. ∗∗, P < 0.01, CAM ICI vs. CAM vehicle; ∗, P < 0.05, CAM vehicle vs. NT (Student’s t test). (B) Adenylate cyclase activity in myocardial particulate fractions. Basal, no added drug; Iso, 100 μM isoproterenol. NT, n = 6; CAM vehicle, n = 6; CAM ICI, n = 5. ∗, P < 0.05, Iso vs. Basal; †, P < 0.05, Iso CAM vehicle vs. Iso NT; ††, P < 0.05, Iso CAM ICI vs. Iso CAM vehicle; ‡, P < 0.05, Basal CAM ICI vs. Basal CAM vehicle; Iso CAM vehicle vs. Basal CAM ICI, P = n.s.
