摘要:
The invention concerns the contribution of elevated levels of circulating alsosterone to heart disease and other hyperaldosteronic conditions. Since activation of β-arrestin 1(βarr1) by the Angiotensin II (AngII) type 1 receptor (AT1R) mediates AngII-induced aldosterone production, β-arrestin 1(βarr1) is a therapeutic target for heart disease. The invention provides a βarr1 protein fragment comprising the C-terminus of βarr1 (βarr1ct; SEQ ID NO:3), compositions containing this protein fragment, and methods of using this protein fragment to reduce elevated levels of aldosterone in heart disease and other hyperaldosteronic conditions by inhibition of β-arrestin 1(βarr1). These compositions and methods are of therapeutic benefit in chronic heart failure and progression to heart failure after myocardial infarction (MI). Additionally, the invention provides an AngII peptide analog (SEQ ID NO:4), compositions containing this analog, and methods of using this analog for stimulation of βarr1 activity and aldosterone production.
摘要:
The disclosure describes the contribution of elevated levels of circulating alsosterone to heart disease and other hyperaldosteronic conditions. Since activation of beta-arrestin I (beta.arr-1) by the Angiotensin II (AngII) type 1 receptor (AT1R) mediates AngII-induced aldosterone production, beta-arrestin I (beta.arr-1) is a therapeutic target for heart disease. Specifically, the disclosure provides a beta.arr-1 protein fragment comprising the C-terminus of beta.arr-1 (beta.arr1ct; SEQ ID NO:3), compositions containing this protein fragment, and methods of using this protein fragment to reduce elevated levels of aldosterone in heart disease and other hyperaldosteronic conditions by inhibition of beta-arrestin (beta.arr-1). These compositions and methods are of therapeutic benefit in chronic heart failure and progression to heart failure after myocardial infarction (MI). Additionally, the invention provides an AngII peptide analog (SEQ ID NO:4), compositions containing this analog, and methods of using this analog for stimulation of beta.arr-1 activity and aldosterone production.

摘要:
The present invention relates to compositions and methods for the treatment of failing hearts. More specifically, the present invention provides for the inhibition of G-protein coupled receptor kinase 2 activity in the adrenal gland, which, for example, decreases catecholamine secretion and the sympathetic burden of the failing heart, thereby improving the cardiac adrenergic/inotropic reserve and overall contractile function.
摘要:
The present invention relates, in general, to vascular smooth muscle proliferation and, in particular, to a method of inhibiting arterial and venous smooth muscle proliferation resulting, for example, from arterial injury or vein grafting. The invention also relates to an expression construct encoding a G&bgr;&ggr; inhibitor suitable for use in such a method.
摘要:
The invention provides nucleic acid segments, compositions and methods for the treatment of heart failure, vascular dysfunction, endothelial dysfunction, diabetes, [Ca2+]i regulation and NO synthase dysfunction. Adeno-associated and adenovirus are used as gene delivery vectors for the nucleic acid segments to product long term over-expression of S100A1, a small calcium sensing protein associated with the disclosed ailments and dysfunctions.

摘要:
The present invention deals with gene therapy for treating chronic heart failure and other cardiac disease states which are accompanied by a reduced number or functioning of myocardial beta-adrenergic receptors (&bgr;-AR). &bgr;-AR receptor function is augmented in transgenic animals by delivery and expression of a beta-2-adrenergic receptor gene or a gene encoding a beta adrenergic receptor kinase inhibitor, resulting in increased in vivo left ventricular function. The present invention includes recombinant plasmid vectors, alternative beta-adrenergic receptor gene delivery strategies, and transgenic mice carrying a &bgr;-AR transgene, a &bgr;-ARK transgene, or a &bgr;-ARK inhibitor transgene.
摘要:
Desensitization of receptors that control disease is prevented by inhibiting G-protein receptor kinases. This has applicability, e.g., for patients with heart failure or on a left ventricular heart device or a heart pump after surgery or about to undergo surgery and at high risk for a cardiac event or on an opiate or addicted to opiate or with cystic fibrosis or rheumatoid arthritis.
