FIG. 4.
Liver mass/body mass ratios of male and female knockout mice compared to those of wild-type littermates at 42 to 45 days of age. Each point represents the mean ± standard error of the mean. There was no ratio from the homozygous mutant groups that statistically differed significantly from the wild-type ratio (P > 0.05). Mice analyzed in this study are as follows: activin βC, wild-type males, n = 7; actβCm1/actβCm1 males, n = 16; wild-type females, n = 6; actβCm1/actβCm1 females, n = 5; activin βE, wild-type males, n = 9, actβEm1/actβEm1 males, n = 13; wild-type females, n = 7; actβEm1/actβEm1 females, n = 15; actβCm1-actβEm1, wild-type males, n = 10; actβCm1-actβEm1 −/− males, n = 17; wild-type females, n = 6; actβCm1-actβEm1 −/− females, n = 12.
