428 Interactive Effects of Neuronal Nitric Oxide Synthase and Cyclooxygenase-2 on Renal Hemodynamics in Cyp1a1-Ren2 Transgenic Rats With Malignant Hypertension
Abstract:Neuronal nitric oxide synthase (nNOS)-derived NO and cyclooxygenase (COX)-2 metabolites exert pronounced renal vasodilator influences in transgenic rats [strain name: TGR(Cyp1a1Ren2] with ANG II-dependent malignant hypertension. This study was performed to determine if the renal vasodilator effects of COX-2 metabolites in hypertensive Cyp1a1-Ren2 rats are dependent on nNOS activity. Male Cyp1a1-Ren2 rats (n = 7) were fed a normal diet containing indole-3-carbinol (0.3%) for 7-9 days to induce malignant hyperte… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
