(A) Female heart mass/body mass ratio (HM/BM) (WT n = 9, ERAP1+/–
n = 6), (B) male HM/BM (WT n = 10, ERAP1+/–
n = 8), (C) female kidney mass/BM ratio (KM/BM) (WT n = 9, ERAP1+/–
n = 7), and (D) male KM/BM (WT n = 10, ERAP1+/–
n = 7). BM of males: WT 32.1 ± 0.6 g (n = 11), ERAP1+/– 31.2 ± 0.5 g (n = 9); females: WT 23.6 ± 0.4 g (n = 9), ERAP1+/– 22.9 ± 0.5 g (n = 7). Data are presented as mean ± SEM; 2-tailed Student’s t tests.
