Figure 5 Expression levels of Ca2+-regulatory proteins. (A) Representative immunoblots showing the amounts of SERCA2a, RyR, phospholamban (PLB), and GAPDH protein levels in left ventricular (LV) tissues from four groups. The amounts of SERCA2a (B), RyR (C), and PLB (D) were quantified by the Odyssey Infrared Imaging System, and the data were normalized to values obtained from LV tissues in the control group. Data represent the mean value ± SEM (Cont, n = 6; Cont+UL, n = 5; DOX, n = 6; DOX+UL, n = 5) A.U. = arbitrary unit; other abbreviations as in Figures 1 and 4.
