    Abstract Heart failure is a problem of increasing importance in cardiovascular medicine. An important characteristic of heart failure is reduced agonist-stimulated adenylyl cyclase activity (receptor desensitization) due to both diminished receptor number (receptor downregulation) and impaired receptor function (receptor uncoupling). These changes in the §-adrenergic receptor (§ AR) system may in part account for some of the abnormalities of contractile function in this disease. Myocardial contraction is closely regulated by G protein coupled β-adrenergic receptors through the action of the second messenger cAMP. The β-adrenergic receptors themselves are regulated by a set of specific kinases, termed the G protein-coupled receptor kinases. The study of this complex system in vivo has recently been advanced by the development of transgenic and gene targeted (“knock out”) mouse models. Combining transgenic technology with sophisticated physiological measurements of cardiac hemodynamics is an extremely powerful strategy to study the regulation of myocardial contractility in the normal and failing heart.

    [Auszug] THE heterotrimeric G proteins1, mol-ecules that have a central role in signal transduction across the cell membrane, are composed of a, ft and y subunits. For several years it was the a subunit which held the limelight, with a great deal of attention being paid to its mediation of the activation of ...
