Fig 7. Renal abundance of the epithelial sodium channel and Na⁺/K⁺-ATPase.

Sixty minutes after vehicle application no differences were observed in (A) αENaC, (B) cleaved αENaC, (C) γENaC or (D) Na⁺/K⁺-ATPase abundance. Systemic administration of dDAVP following suppression of endogenous arginine-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.
