 This study will test the hypothesis that administration of a PPARa agonist, an intervention increases renal tubular Cyp2c and 4a expression in rodents, will increase urinary excretion of 20-hydroxyeicosatetraenoic acidHETE and epoxyeicosatrienoic acidsEETs, induce natriuresis, decrease blood pressure, and improve insulin sensitivity during high-salt intake in individuals with hypertension.
