Descripción
We have previously shown that ovariectomy in adult Wistar rats under normal sodium (NS) intake results in an overexpression of total Na+, K+-ATPase α 1subunit (NKA). Upon high sodium (HS) intake ovariectomized (oVx) rats developed a defective NKA phosphorylation, a decrease in sodium excretion, and an increment in mean blood pressure (MBP). Since NKA phosphorylation is modulated by dopamine (DA), the aim of this study was to compare the intracellular response of the renal DA system leading to NKA phosphorylation upon sodium challenge in intact female (IF) and oVx rats. In IF rats HS caused an increase in urinary DA and sodium, in NKA phosphorylation state, in Cytochrome P4504A (CYP4A) expression and in 20-HETE production, while MBP kept normal. Blockade of D1R with the D1-like receptor antagonist SCH23390 in IFHS rats shifted NKA into a more dephosphorylated state, decreased sodium excretion by 50 % and increased MBP. In oVxNS rats, D1R expression was reduced and D3R expression was increased, and under HS intake sodium excretion was lower and MBP higher than in IFHS rats (both p<0.05), NKA was more dephosphorylated than in IFHS and CYP4A expression or 20-HETE production did not change. Blockade of D1R in oVxHS rats changed neither NKA phosphorylation state nor sodium excretion or MBP. D2R and PKCα expression did not vary among groups. The alteration of the renal dopamine system produced by ovariectomy could account for the defective NKA phosphorylation, the inefficient excretion of sodium load and the development of salt sensitive hypertension.
