008 Neuronal nitric oxide synthase-mediated regulation of myocardial redox state and β3 adrenergic receptor responses

Recent evidence suggests that increased superoxide production may decrease the bioavailability of endothelial nitric oxide synthase (eNOS)-derived nitric oxide in the myocardium of neuronal nitric oxide synthase (nNOS)−/− mice. To test the functional relevance of this observation, we compared the eNOS-dependent inotropic and [Ca2+]i transient effect of beta3-adrenergic receptor (β3-AR) stimulation in left ventricular myocytes from eNOS …
