As we have previously shown, activation of either estrogen receptor subtype, ERα or ERβ, is fully sufficient to attenuate vascular remodeling in aldosterone salt-treated rats. To further elucidate the underlying mechanism(s) we tested the hypothesis that ER and MR activation might differentially modulate vascular reactive oxygen species (ROS) generation. In support of this concept, aldosterone increased ROS generation in vascular smooth muscle cells as determined by quantitative dihydroethidium fluorescence microscopy. Co-treatment with the selective ERα agonist 16α-LE2, the selective ERβ agonist 8β-VE2 or the non-selective ER agonist 17β-estradiol (E2) significantly reduced aldosterone-induced ROS generation. The pure ER antagonist ICI 182,780 completely blocked these salutary effects of E2, 16α-LE2 and 8β-VE2. Activation of ERα or ERβ fully blocked the reduction of intracellular nicotinamide adenine dinucleotide phosphate (NADPH) levels observed in aldosterone treated vascular smooth muscle cells. Intracellular NADPH levels were closely associated with expression and activity of the NADPH generating enzyme glucose-6-phosphate dehydrogenase. In conclusion, estrogens attenuate the detrimental vascular effects of excessive MR activation at least in part by preventing the depletion of intracellular NADPH levels."xsd:string |
