Requisite Role of Cardiac Myocytes in Coronary a1-Adrenergic Constriction
Background—a-Adrenergic activation in vivo causes constriction of coronary arterioles, but, paradoxically, in vitro these microvessels do not contract to this stimulus. We hypothesized that cardiac myocytes have a requisite role in a1-adrenergic coronary arteriolar constriction through the release of myocyte-derived contractile factor(s). Methods and Results—Administration of the a1-adrenergic ...

متن کاملEndothelin antagonists block α1-adrenergic constriction of coronary arterioles.
We have previously observed that intracoronary administration of the α1-adrenergic agonist phenylephrine (PE) over a period of minutes induced both an immediate and long-lasting (2 h) vasoconstriction of epicardial coronary arterioles. Because it is unlikely that α1-adrenergic constriction would persist for hours after removal of the agonist, this observation supports the view that another cons...
متن کاملα1-Adrenergic stimulation of FGF-2 promoter in cardiac myocytes and in adult transgenic mouse hearts.
Fibroblast growth factor (FGF-2), a mitogenic, angiogenic, and cardioprotective agent, is reported to be released from the postnatal heart by a mechanism of transient remodeling of the sarcolemma during contraction. This release can be increased with adrenergic stimulation. RNA blotting was used to assess whether FGF-2 synthesis in neonatal rat cardiomyocytes might also be regulated by adrenerg...
متن کاملNuclear Compartmentalization of α1-Adrenergic Receptor Signaling in Adult Cardiac Myocytes
Although convention dictates that G protein-coupled receptors localize to and signal at the plasma membrane, accumulating evidence suggests that G protein-coupled receptors localize to and signal at intracellular membranes, most notably the nucleus. In fact, there is now significant evidence indicating that endogenous alpha-1 adrenergic receptors (α1-ARs) localize to and signal at the nuclei in...
