2 A, Arterial blood pressure, (B) glomerular filtration rate, and (C) renal blood flow in Hsd11b2+/+ (☐) and Hsd11b2+/− (▩) mice after 3 weeks on low-sodium (LS; n=7 and 8), standard-sodium (SS; n=8 and 8), or high-sodium (HS; n=9 and 11) diet. A, Arterial blood pressure, (B) glomerular filtration rate, and (C) renal blood flow in Hsd11b2+/+ (☐) and Hsd11b2+/− (▩) mice after 3 weeks on low-sodium (LS; n=7 and 8), standard-sodium (SS; n=8 and 8), or high-sodium (HS; n=9 and 11) diet. Data are mean±SEM. Comparisons were made using ANOVA with Bonferroni post hoc test. *P<0.05; **P<0.01. Eilidh Craigie et al. Hypertension. 2012;60: Copyright © American Heart Association, Inc.

3 A, Fractional sodium excretion, (B) fractional potassium excretion, (C) amiloride-sensitive sodium reabsorption (ΔamilorideNa), and (D) amiloride sensitive potassium secretion (ΔamilorideK) in Hsd11b2+/+ (☐) and Hsd11b2+/− (▩) mice after 3 weeks on low-sodium (LS; n=7 and 8), standard-sodium (SS; n=8 and 8), or high-sodium (HS; n=9 and 11) diet.
