Effects of overnight (o/n) Na depletion on ENaC and pNCC expression. Right: Western blots showing expression of ENaC subunits and NCC and pNCC for animals fed either a control or low-Na diet overnight. In this blot the two left-hand lanes in each group were from female rats, whereas the two right-hand lanes used males. Females had a higher expression of NCC protein but changes were similar in the two sexes. Left: densitometric analysis. Data represent means ± SE for 8 animals. *Statistical significance (P < 0.05).
