Fluid intake and sodium preference are largely normal in AT1AAVP-KO mice. A–D: fluid intake (A), food intake (B), preference for the NaCl drink (C), and total sodium intake (D) in mice receiving the option to drink water plus an indicated comparator drink with varied concentrations of NaCl dissolved in water in an alternating 2-bottle choice paradigm. Data are expressed as means ± SE. *P < 0.05, overall between genotypes; #P < 0.05 compared with corresponding treatment between genotypes (control: male n = 15, female n = 12; AT1AAVP-KO: male n = 6, female n = 6).
