CRAMP attenuates AngII-induced heart failure. In the AngII-infused mice model, mCRAMP peptide improved EF and FS (A, n=8 in Vehicle+Control, 8 in CRAMP+Control, 8 in Vehicle+AngII, and 10 in CRAMP+AngII), decreased cell size (B, n=8 in Vehicle+Control, 7 in CRAMP+Control, 8 in Vehicle+AngII, and 7 in CRAMP+AngII)(C, n=5 in Vehicle+Control, 8 in CRAMP+Control, 5 in Vehicle+AngII, and 6 in CRAMP+AngII), cardiac fibrosis (D, n=7 in Vehicle+Control, 8 in CRAMP+Control, 4 in Vehicle+AngII, and 6 in CRAMP+AngII), collagen 1, the ratios of Bax/BCl2 and cleaved caspase 3/caspase 3 (E, n=3 per group), and ANP and BNP levels (F, n=6 per group). *, P<0.05; **, P<0.01; ***, P<0.001.
