Endothelin-1, aging and hypertension [PDF]
Endothelin-1 system activation plays an important role in the etiology of atherosclerotic vascular disease. Aging and hypertension are two independent cardiovascular risk factors that have been shown to exhibit increased endothelin-1 system activation. This review focuses on the cardiovascular effects of the endothelin system, its relation to aging and

Assessing candidate DLX‐regulated genes in the first pharyngeal arch of chick embryos
Abstract Background Insights into the development and evolution of asymmetrical jaws will require an understanding of the gene regulatory networks that underpin the differential morphogenesis of the maxillary and mandibular domains of the first pharyngeal arch in a variety of gnathostomes.

Clinical trials with endothelin receptor antagonists: What went wrong and where can we improve? [PDF]
In the early 1990s, within three years of cloning of endothelin receptors, orally active endothelin receptor antagonists (ERAs) were tested in humans and the first clinical trial of ERA therapy in humans was published in 1995.

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Modulation of endothelin-1-induced contractions by magnesium/calcium in porcine ciliary arteries [PDF]
• Background: The present study was performed to investigate the influence of extracellular magnesium on changes in contractile tone induced by endothelin-1, and on relaxations to bradykinin in isolated porcine ciliary arteries.

Effects of calcium channel blockers on coronary vasoconstriction induced by endothelin-1 in closed chest pigs [PDF]
The purpose of this study was to determine the effects of endothelin-1 on the coronary vascular bed of closed chest pigs. Endothelin-1 (3 to 30 pmol/kg body weight) was selectively administered into the left anterior descending coronary artery.

There is some controversy regarding whether vascular responses to endothelin are altered in hypercholesterolemia. Studies performed to date have been compromised by the use of endothelin antagonists at inappropriate concentrations.

Endothelin-1 in cardiovascular physiology [PDF]
Endothelin-l (ET -1) is a 21 amino acid peptide endowed with a a powerful vasoconstrictor activity. The molecular structure and biological activities of endothelin were explored in several studies starting soon after its discovery in 1988, but only recently has the availability of specific ET -1 antagonists allowed its physiological activities to be ...

Cardiac remodelling in the era of the recommended four pillars heart failure medical therapy
Abstract Cardiac remodelling is a key determinant of worse cardiovascular outcome in patients with heart failure (HF) and reduced ejection fraction (HFrEF). It affects both the left ventricle (LV) structure and function as well as the left atrium (LA) and the right ventricle (RV).

Hemodynamic and inotropic effects of endothelin-1 in vivo [PDF]
Endothelin-1 (ET-1) is known to have strong vasoactive properties. Contradictory results have been reported with regard to its inotropic effects. This study examined the dose-dependent (500, 1000, 2500, 5000 and 10,000 ng ET-1/kg vs.
