(a) Columns indicated the calculated left ventricular systolic pressure (LVSP) and left ventricular diastolic pressure (LVDP) in rats in control, AGE, and AGE + Se groups. (b) Columns indicated the detected BNP concentrations in blood samples collected from rats in control, AGE, and AGE + Se groups. (c) Captured fluorescent images of TUNEL assay of cardiac tissue. TUNEL-positive cells were tagged with red fluorescence and pointed by yellow arrows. Columns indicated the apoptosis rate in cardiac tissue harvested from rats in control, AGE, and AGE + Se groups, respectively. (d) Immunoblots of caspase3, cleaved caspase3 (c-caspase3), and GAPDH were demonstrated. Columns indicated relative expression levels of c-caspase3 in cardiac tissue harvested from rats in control, AGE, and AGE + Se groups, respectively. Magnification of images in Figure 1(a) was 200 (control: rats treated with control BSA; AGEs: rats treated with AGE-BSA; AGEs + Se: rats treated with AGE-BSA then supplemented with sodium selenite (n = 6, ∗P < 0.05)).
