AIMS Sympathetic regulation of cardiac contractility is mediated in part by α(1)-adrenergic receptors (ARs), and the α(1A)-subtype has been implicated in the pathogenesis of cardiac hypertrophy. However, little is known about α(1A)-AR signalling pathways in ventricular myocardium. The aim of this study was to determine the signalling pathway that mediates(More)
AIMS To determine the mechanisms by which the α1A-adrenergic receptor (AR) regulates cardiac contractility. BACKGROUND We reported previously that transgenic mice with cardiac-restricted α1A-AR overexpression (α1A-TG) exhibit enhanced contractility but not hypertrophy, despite evidence implicating this Gαq/11-coupled receptor in hypertrophy.
