Fig. 2. Effect of DEX on the expression of Na⁺/K⁺-ATPase, Na⁺/K⁺/2Cl^– cotransporter (NKCC) and Na⁺/H⁺ exchanger-1 (NHE-1) in pavement cells (PVCs) in culture. The cells were exposed to 0.5–2 µmol l^–1 DEX for 24 h. (A) Cell lysates were collected for western blot analysis and (B) the amounts of the respective ion transporter proteins were quantified. Note that the three transporters were significantly induced. *P<0.05 compared with the control. The results were obtained from more than four independent experiments.
