Figure 7.

Plasma K⁺ concentrations in kidney tubule-specific neural precursor cell expressed developmentally downregulated 4-2 knockout (Ks-Nedd4-2 KO) mice and floxed neural precursor cell expressed developmentally downregulated 4-like (Nedd4^fl/fl) mice on different K⁺ diets. The bar graph shows plasma K⁺ concentrations in control mice [normal K⁺ (NK): n = 5 mice (3 male/2 female); low K⁺ (LK): n = 5 mice (3 male/2 female); high K⁺ (HK) for 7 days: n = 5 mice (3 male/2 female); and HK for 14 days: n = 4 mice (2 male/2 female)] and Ks-Nedd4-2 KO mice [NK: n = 5 mice (3 male/2 female); LK: n = 7 mice (4 male/3 female); HK for 7 days: n = 7 mice (4 male/3 female); and HK for 14 days: n = 4 mice (2 male/2 female)]. Individual data points are indicated by black circles. Significance was determined by two-way ANOVA.
