Figure 3. CaMKIIβ KO mice have a developmental delay in body weight.

(A) CaMKIIβ^+/+ and CaMKIIβ^−/− mice were weighed at birth, or starting at weaning (3 weeks old) until 4 months of age. n = 5–13/time point. (B) Echo MRI was used to determine lean/fat mass in 12 week old mice. No genotype effect was seen in the amount of water (C) or in the amount of food (D) consumed, or in respiratory exchange ratio (E). *p<0.05, **p<0.01. Data are presented as means ±SEM. n = 4–6 per group in panels B–E.
