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

Figure 5 Covalent modifications of carnitine palmitoyltransferase-1 measured by immunoprecipitation. Rat heart samples underwent immunoprecipitation with combined pan-specific anti-phosphoserine and anti-phosphothreonine antibodies, anti-glutathione antibodies or anti-nitrosocysteine antibodies, followed by immunoblotting with pan-specific carnitine palmitoyltransferase (CPT)-1 antibodies. Densitometric analyses of these data are presented in Figure 6. 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.
