Changes in apoptosis in WT and NLRP3−/− mice during aging and melatonin treatment. (A) Protein levels of p53. (B) Protein levels of caspase 9. (C) Protein levels of Bax. (D) Protein levels of Bcl2. (E) Bax/Bcl2 ratio. Experiments were performed in hearts of young (Y), early-aged (EA), early-aged with melatonin (EA + aMT), old-aged (OA), and old-aged with melatonin (OA + aMT) wild type and NLRP3−/− mice. Data are expressed as means ± SEM (n = 7 animals/group). * p < 0.05, ** p < 0.01 vs. Y; # p < 0.05, ## p < 0.01 vs. group without melatonin treatment.
