abstract
Dysregulated nitric oxide (NO) signaling contributes to the pathogenesis of hypertension, a prevalent and often sex-specific risk factor for cardiovascular disease. We previously reported that mice deficient in the alpha(1)-subunit of the NO receptor soluble guanylate cyclase (sGC(alpha 1)(-/-) mice) display sex-and strain-specific hypertension: male but not female sGC(alpha 1)(-/-) mice are hypertensive on an 129S6 (S6) but not a C57BL6/J (B6) background. We aimed to uncover the genetic and molecular basis of the observed sex-and strain-specific blood pressure phenotype. Via linkage analysis, we identified a suggestive quantitative trait locus associated with elevated blood pressure in male sGC(alpha 1)(-/-) S6 mice. This locus encompasses Cyp4a12a, encoding the predominant murine synthase of the vasoconstrictor 20-hydroxy5,8,11,14- eicosatetraenoic acid (20-HETE). Renal expression of Cyp4a12a in mice was associated with genetic background, sex, and testosterone levels. In addition, 20-HETE levels were higher in renal preglomerular microvessels of male sGC(alpha 1)(-/-) S6 than of male sGC(alpha 1)(-/-) B6 mice. Furthermore, treating male sGC(alpha 1)(-/-) S6 mice with the 20-HETE antagonist 20-hydroxyeicosa-6(Z), 15(Z)-dienoic acid (20-HEDE) lowered blood pressure. Finally, 20-HEDE rescued the genetic background-and testosterone-dependent impairment of acetylcholine-induced relaxation in renal interlobar arteries associated with sGC(alpha 1)(-/-) deficiency. Elevated Cyp4a12a expression and 20-HETE levels render mice susceptible to hypertension and vascular dysfunction in a setting of sGC(alpha 1)(-/-) deficiency. Our data identify Cyp4a12a as a candidate sex-specific blood pressure-modifying gene in the context of deficient NO-sGC signaling.
