Sodium balance under a sodium replete control diet in Habp2^+/+ and Habp2^−/− mice before and on day 7 of experimental nephrotic syndrome.

	Healthy		Nephrotic
	Habp2+/+	Habp2−/−	Habp2+/+	Habp2−/−
Total Na+ intake, µmol 24 h−1	245 ± 26	265 ± 38	291 ± 38	261 ± 39
Urinary Na+ excretion, µmol 24 h−1	103 ± 22	108 ± 13	12 ± 4#	10 ± 3#
Fecal Na+ excretion, µmol 24 h−1	24 ± 4	37 ± 4*	13 ± 3#	11 ± 1#
Na+ balance, µmol 24 h−1	118 ± 22	120 ± 33	266 ± 36#	239 ± 37#

Arithmetic means ± SEM (n = 6 each). Note that the body weight was similar in Habp2^+/+ and Habp2^−/− mice (25.6 ± 0.9 g vs. 24.7 ± 1.3 g, p = 0.59). #Significant difference between healthy and nephrotic mice; *significant difference between genotypes
