growth/size/body

increased body weight ( J:213555 )

increased systemic arterial systolic blood pressure ( J:213555 )

• mutant mice fed a high K+ (5% KCl) diet display significantly increased systolic BP and remain hypertensive for 3 days during increased K+ intake, unlike wild-type controls

• mutant mice fed a high-salt (4% NaCl) diet for 3 days show no significant differences in mean systolic BP relative to wild-type controls
