Baseline MAP, RBF, and RVR in βENaC +/+ and m/m mice following volume expansion

	Genotype
	βENaC +/+	βENaC m/m	P Value*
MAP, mmHg	97 ± 5	94 ± 4	0.68
RBF, ml · min−1 · g kidney wt−1	6.5 ± 0.9	6.5 ± 0.7	0.98
RVR, mmHg · ml−1 · min−1 · g kidney wt	16.9 ± 3.4	15.7 ± 2.0	0.75
Sample size, n	6	7
Age, wk	18.6 ± 1.9	15.7 ± 1.7	0.52

Values are means ± SE; n, no. of mice. MAP, mean arterial pressure; RBF, renal blood flow; RVR, renal vascular resistance; βENaC, β-epithelial Na⁺ channel; ENaC m/m, mouse model of reduced βENaC.

^*P value from 2-tailed t-test.
