ABSTRACT
Aim To investigate the inotropic effect of PF-04957325, a phosphodiesterase type 8 inhibitor, in normal rats and its underlying molecular mechanism. Methods The techniques of in vivo rat left ventricular pressure-volume loop (P-V loop) and isolated perfusion rat heart were used to analyze the hemodynamics and positive inotropic effect of rat hearts. The Ca transient induced by field stimulation was used to analyze the hemodynamics of sarcoplasmic reticulum (SR) Ca + uptaking. Western blot was used to analyze the phosphorylation levels of SR phospolamban (PLB) and ryanodine receptor type 2 (RyR2). Results The P-V loop experiment indicated that PF-04957325 (0.5 mg · kg
