BACKGROUND Evidence indicates that myocardial NO production can modulate contractility, but the source of NO remains uncertain. Here, we investigated the role of a type 1 NO synthase isoform (NOS1), which has been recently localized to the cardiac sarcoplasmic reticulum, in the regulation of basal and beta-adrenergic myocardial contraction. METHODS AND RESULTS Contraction was assessed in left ventricular myocytes isolated from mice with NOS1 gene disruption (NOS1(-/-) mice) and their… CONTINUE READING
