Af17−/− mice fed the normal Na+ diet showed impaired renal function and decreased BP, despite mildly increased plasma aldo. Af17+/+ (n = 34) and Af17−/− (n = 37) mice fed the normal Na+ diet in metabolic cages were analyzed for the parameters as indicated. For BP measurement, n = 57 mice for Af17+/+ and n = 65 mice for Af17−/−. For all other parameters, n = 6 to 37 mice/group. For additional parameters, see Supplemental Figure S1. In all cases, *P < 0.05 versus Af17+/+.
