Endothelin-1 and Vasomotor Tone Following Cardioplegic Ischemia/Reperfusion and Cardiopulmonary Bypass [PDF]
Endothelin-1 is a potent regulator of vasomotor tone and promotes endothelium-dependent vasoconstriction of vascular smooth muscle. Dysregulated vasomotor tone is a hallmark of microvascular pathology following cardiac surgery involving cardioplegia and ...

The gastrointestinal endothelin system: receptors, cellular actions, and involvement in gastrointestinal disorders [PDF]
The gastrointestinal endothelin system regulates vital processes including motility, secretion, sensation, and inflammation. Endothelin-1 acts via endothelin A and B receptors expressed on diverse intestinal cells.

Structural basis of peptide recognition and activation of endothelin receptors
Endothelin receptors (ETAR and ETBR) are critical for vasoregulation and are targets for cardiovascular diseases treatment. Here, the authors offer a structural basis for peptide recognition selectivity and activation of both endothelin receptors.

Myocardial ischemia-reperfusion enhances transcriptional expression of endothelin-1 and vasoconstrictor ETB receptors via the protein kinase MEK-ERK1/2 signaling pathway in rat. [PDF]
BACKGROUND:Coronary artery remodelling and vasospasm is a complication of acute myocardial ischemia and reperfusion. The underlying mechanisms are complex, but the vasoconstrictor peptide endothelin-1 is suggested to have an important role.

Endothelin‐receptor interactions [PDF]
The mechanism of action of endothelin‐receptor interactions was studied, using radioligand binding assays and SDS‐PAGE, to investigate the possibility of disulfide interchange. Electrophoretic analysis suggested involvement of disulfide bond(s) in the receptor‐ligand complex.

Affinity labelling of endothelin receptor and characterization of solubilized endothelin–endothelin‐receptor complex [PDF]
Chick cardiac membranes were affinity labelled by cross‐linking to membrane‐bound 125I‐endothelin‐1 with disuccinimidyl tartarate. SDS/PAGE and autoradiographic analysis of the 125I‐endothelin‐1‐labelled material in the presence or absence of 2‐mercaptoethanol revealed one major labelled band, corresponding to a molecular mass of 53 kDa, whose ...

Endothelin Receptors and Pain [PDF]
The endogenous endothelin (ET) peptides participate in a remarkable variety of pain-relatedprocesses. Pain that is elevated by inflammation, by skin incision, by cancer, during a Sickle Cell Disease crisis and by treatments that mimic neuropathic and inflammatory pain and are all reduced by local administration of antagonists of endothelin receptors ...

Endothelin and the Cardiovascular System: The Long Journey and Where We Are Going
Endothelin was first discovered more than 30 years ago as a potent vasoconstrictor. In subsequent years, three isoforms, two canonical receptors, and two converting enzymes were identified, and their basic functions were elucidated by numerous ...
