Abstract

Endothelium-dependent vasodilation is attenuated in humans and experimental hypertension models, and this phenomenon may be largely due to decreased release or activity of nitric oxide (NO). However, very few studies have evaluated whether beta-adrenoceptor antagonists increase endothelial NO synthase (eNOS) expression in the left ventricle. We examined the effects of long-term treatment with celiprolol, a specific beta1-antagonist with a weak beta2-agonist action, on eNOS expression in the left ventricle and evaluated its relationship to myocardial remodeling in the left ventricle of deoxycorticosterone acetate (DOCA)-salt hypertensive rats. DOCA-salt rats (n = 18) were induced with weekly injections of DOCA (30 mg/kg) and 1% saline in their drinking water after right nephrectomy. Celiprolol (DOCA-CEL, n = 9, 10 mg/kg per day, subdepressor dose) or a vehicle (DOCA-V, n = 9) were given after induction of DOCA-salt hypertension for 5 weeks, and age-matched sham-operated rats (ShC, n = 9) served as a control group. Blood pressure levels in DOCA-V and DOCA-CEL were similar and significantly higher than that in ShC. The eNOS mRNA and protein levels, and NOS activity in the left ventricle significantly decreased in DOCA-V compared w...Continue Reading

Cardiac Remodeling

Cardiac remodeling in response to a myocardial infarction is characterized by progressive ventricular dilatation, cardiac hypertrophy, fibrosis, and deterioration of cardiac performance. Discover the latest research on Cardiac Remodeling here.

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
