Fig 6. Renal abundance of major salt and proton transporting proteins.

Sixty minutes after vehicle application no differences were observed in (A) NHE3, (B) NKCC2, (C) NCC or (D) H⁺-ATPase abundance. Systemic administration of dDAVP following suppression of endogenous vasopressin overnight (see Materials and methods for details) did not affect abundances of these proteins. Data are expressed as mean ± SEM and analyzed by paired and unpaired Student’s t-test, n = 5 each genotype and condition.
