Dietary salt intake increases hypothalamic γ ENaC, VP, and OT expression in Dahl‐SS. (A) Dahl‐SS rats fed high salt diet for 21 days had significantly higher γ ENaC, VP, and OT mRNA expression in the hypothalamus compared to animals fed control diet, whereas MR, α‐ and β ENaC hypothalamic mRNA expression was not affected by dietary treatment. (B) No significant difference was detected in ENaC mRNA expression in the kidney between animals fed high salt diet or control. (C) Dahl‐SS fed high salt diet had significantly higher plasma osmolality compared to those fed control diet.
