Parallel effects of β-adrenoceptor blockade on cardiac function and fatty acid oxidation in the diabetic heart: Confronting the maze

Figure 7 Co-immunoprecipitation of protein kinase A and A-kinase anchoring protein-149 with carnitine palmitoyltransferase-1, and phosphorylation state of A-kinase anchoring protein-149. Densitometric analyses of these data are presented in Figure 8. AKAP: A-kinase anchoring protein; PKA: Protein kinase A; CPT: Carnitine palmitoyltransferase; C: Control, n = 5; CP: Control perfused with metoprolol, n = 5; CT: Control treated with metoprolol, n = 5; D: Diabetic, n = 5; DP: Diabetic perfused with metoprolol, n = 5; DT: Diabetic treated with metoprolol, n = 5.
