Introduction. Urotensin II (U II) is a kind of active peptide with variety biological effects, such as promoting cell proliferation and endocrine effects. The aim this study to investigate the effect urotensin on secretion vascular endothelial growth factor (VEGF) in cultured rat dermal papilla cells (DPCs), explore its molecular mechanism. Materials Methods. We used DPCs isolated from thoracic...
Urotensin-II (U-II) is a cyclic peptide that acts through a specific G-protein-coupled receptor, UT receptor. Urotensin-II and UT receptors have been described in pancreas and kidney, but their function is not well understood. We studied the effects of chronic treatment of diabetic rats with the orally active selective U-II receptor antagonist palosuran. Streptozotocin treatment causes pancreat...
Aim: This study was conducted to investigate the diagnostic importance of Urotensin II (UT-II) levels, which cause vasodilation as a compensation mechanism in early phase Acute Mesenteric Ischemia (AMI). For this purpose, human plasma urotensin studied for first time literature diagnosis mesenteric ischemia.
 Material and Method: The consisted 60 patients. patients were divided into three ...
Urotensin-II was originally isolated from the goby urophysis in the 1960s as a vasoactive peptide with a prominent role in cardiovascular homeostasis. The identification of human isoform of urotensin-II and its specific UT receptor by Ames et al. in 1999 led to investigating the putative role of the interaction U-II/UT receptor in multiple pathophysiological effects in humans. Since urotensin-I...
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 ...
We studied single nucleotide polymorphisms (SNPs) and haplotypes in the urotensin-II (UTS2) and urotensin-II receptor gene (UTS2R) in Hong Kong Chinese (224 hypertensive and 306 normotensive unrelated subjects) and their relation to hypertension and the metabolic syndrome. For UTS2, the GGT haplotype (–605G, 143G, 3836T) was associated with higher plasma level of U-II and insulin, and higher ho...

For UTS2, the GGT haplotype (-605G, 143G and 3836T) was associated with higher plasma level of U-II and insulin, and higher...
In the present study, we examined the effects of central administration of Urotensin II on blood pressure, heart rate, and baroreceptor heart rate reflexes in conscious normotensive rabbits. Preliminary operations were undertaken to implant a balloon cuff on the inferior vena cava for baroreflex assessments and to implant cannula into the lateral and fourth ventricle. After 2 weeks of recovery ...
Urotensin II (U-II) is the most potent vasoconstrictor known, even more potent than endothelin-1. It was first isolated from the fish spinal cord and has been recognized as a hormone in the neurosecretory system of teleost fish for over 30 years. After the identification of U-II in humans and the orphan human G-protein-coupled receptor 14 as the urotensin II receptor, UT, many studies have show...
