Na⁺-K⁺-ATPase activity and Expression of Na⁺-K⁺-ATPase α1 protein. Na⁺-K⁺-ATPase activity (a) and expression of Na⁺-K⁺-ATPase α1 protein (b) in the renal proximal tubules of different experimental groups: Control (vehicle-treated), clofibrate (clofibrate 250 mg/kg; i.p.), L-NAME (L-NAME; 100 mg/kg; p.o.), Clofibrate/L-NAME (Clofibrate and L-NAME), NaCl (2% NaCl in drinking water), Clofibrate/NaCl (clofibrate and NaCl) or WY14643 (WY14643; 45 mg/kg; i.p.). Values are mean ± SEM. Values in parentheses are the number of animals. *-p < 0.05 versus Ccontrol. #-p < 0.05 versus Clofibrate. @-p < 0.05 versus NaCl.
