Abstract:
The present invention provides methods, compounds, pharmaceutical compositions, and kits for the augmentation of erythropoiesis by potentiating erythropoietin-induced differentiation with angiotensinogen, angiotensin I (AI), AI analogues, AI fragments and analogues thereof, angiotensin II analogues, AII fragments or analogues thereof or AII AT2 type 2 receptor agonists as a therapeutic adjunct. The method is useful for the treatment of congenital or acquired aplastic or hypoplastic anemia associated with chronic renal failure, end-stage renal disease, renal transplantation, cancer, AIDS, chemotherapy, radiotherapy, bone marrow transplantation and chronic diseases.
Abstract:
The present invention provides methods, improved cell culture medium and kits for promoting hematopoietic and mesenchymal stem and lineage-specific cell proliferation and differentiation by growth in the presence of angiotensinogen, angiotensin I (AI); AI analogues, AI fragments and analogues thereof, angiotensin II (AII), AII analogues, AII fragments or analogues thereof or AII AT2 type 2 receptor agonists, either alone or in combination with other growth factors and cytokines.
Abstract:
Methods and compositions for treating patients having erectile dysfunction are described. The method involves the step of treating a patient with a combination of an AT1 specific Angiotensin II antagonist and Angiotensin II agonist. Preferably the AT1 specific Angiotensin II antagonist is an AT1 specific Angiotensin II antagonist. The composition is a pharmaceutical composition including an equivalent molecular ratio of an AT1 specific Angiotensin II antagonist and Angiotensin II agonist.
Abstract:
A method for treating patients having bladder dysfunction is described. The method involves the step of treating a patient with a renin-angiotensin system inhibitor. Preferably the inhibitor is an Angiotensin II antagonist, an ACE inhibitor, or a renin inhibitor. Compositions of a combination of an AT1 specific Angiotensin II antagonist and an Angiotensin II agonist are also described. The compositions are useful for treating bladder dysfunction.
Abstract:
Angiotensin IV (VAL-TYR-ILE-HIS-PRO-PHE), a degradation product of angiotensin II previously thought to be inactive, interacts directly with endothelial cells to induce expression of PAI-1 and thereby to inhibit clot lysis attributable to endogenous t-PA. Moreover, angiotensin IV does not effect substantial physiological changes (vasoconstriction, increased blood pressure, etc.) characteristic of angiotensin II. Fibrinolysis is promoted by reducing the amount or the effect of angiotensin IV. Fibrinolysis is inhibited by providing enhanced angiotensin IV. Methods of screening candidates for antagonizing angiotensin IV are also disclosed.
Abstract:
The use of des-Aspartate-angiotensin I (Arg-Val-Tyr-Ile-His-Pro-Phe-His-Leu) as an anti-cardiac hypertrophic agent is described. The compound, given either intravenously or orally, prevented the development of experimentally-induced cardiac hypertrophy in rats. Its action was dose-dependent and the maximum anti-cardiac hypertrophic effect was obtained at a dose of (i) 180 mg/day when given intravenously, and (ii) 285 mg/day when given orally.
Abstract:
The present disclosure relates to the use of angiotensin II, angiotensin III, or angiotensin IV in therapeutic methods for the treatment of hypotension, especially catecholamine-resistant hypotension.
Abstract:
The present invention relates, e.g., to a method comprising administering to a subject having high output shock and undergoing treatment with a catecholamine at a dose equivalent to at least about 0.2 mcg/kg/min of norepinephrine a dose of angiotensin II which is effective to raise the blood pressure of the subject to a mean arterial pressure (MAP) of about 65 mm Hg or above, and which is effective to reduce the dose of the catecholamine required to maintain a MAP of about 65 mm Hg to the equivalent of about 0.05-2.0 mcg/kg/min norepinephrine or less, or to the equivalent of about 0.05 mcg/kg/min norepinephrine or less.
