Genetic and pharmacological manipulation of urotensin II ameliorate the metabolic and atherosclerosis sequalae in mice.

The roles of potassium channels in contractile response to urotensin-II in mercury chloride induced endothelial dysfunction in rat aorta

Urotensin-II (U-II), the most potent vasoconstrictor that has recently been recognized as a new candidate in cardiovascular dysfunction, might exert vasoconstriction through, at least partially, potassium channels that are predominant in both endothelial and vascular smooth muscle cells (VSMCs). The present study was designed to evaluate the roles of potassium channels in vascular responses to ...

Differential Metabolic Effects of Novel Cilostamide Analogs, Methyl Carbostiryl Derivatives, on Mouse and Hyperglycemic Rat

Objective(s) PDE3 has a functional role in insulin secretion and action. We investigated the metabolic effects of new synthetic PDE3 inhibitors (mc1, mc2, mc5 and mc6), on mice and hyperglycemic rat. Materials and Methods The test compound or solvent was injected subcutaneously to mice, for 7 days. On day 8, blood and liver samples were obtained. In hyperglycemic rat, 0.5 g/kg glucose with o...

Integrative Physiology Urotensin II Receptor Knockout Mice on an ApoE Knockout Background Fed a High-Fat Diet Exhibit an Enhanced Hyperlipidemic and Atherosclerotic Phenotype

Effects of Resveratrol on the Level of Urotensin II and its Receptors in the Homogenized Tissue of Diabetic Rats

Background: Individuals with diabetes mellitus are at serious risk of a wide range of cardiovascular complications. Urotensin 2 and its receptors play an important role in the development of cardiovascular diseeases through production of reactive oxygen species (ROS). Resveratrol is a polyphenol with antioxidant and anti-diabetic properties. The present study aimed to investigate the effects of...

The Role of Urotensin II in Health and Disease

Urotensin II (UII) is an 11 amino acid cyclic peptide originally isolated from the goby fish. The amino acid sequence of UII is exceptionally conserved across most vertebrate taxa, sharing structural similarity to somatostatin. UII binds to a class of G-protein coupled receptor known as GPR14 or the urotensin receptor (UT). UII and its receptor UT are widely expressed throughout the cardiovascu...
