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...

Urocortin, is a recently isolated peptide belonging to the CRH family that binds with high affinity to the CRH2 receptor. Like CRH, urocortin causes hypotension in the rat, but its vasoactive actions have not yet been studied in the human. We have compared the vasoactive properties of urocortin, CRH, and urotensin-1 in the human fetal placental vasculature in vitro. Single placental lobules wer...

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...

The use of the unlabeled antibody enzyme method on serially adjacent sections permitted the demonstration of urotensin II (UII) and urotensin I (UI) immunoreactivities colocalized in most of the cells of the caudal neurosecretory system of Catostomus commersoni. The study of the upper regions of the central nervous system from the spinal cord anterior to the fifth preterminal vertebral region u...

Corticotropin-releasing factor (CRF)-related peptides exhibit different affinity for the receptor subtypes 1 and 2 cloned in the rat brain. We investigated, in conscious rats, the effects of intracisternal (IC) injection of CRF (rat/human) on the 5-h rate of gastric emptying of a solid nutrient meal (Purina chow and water ad libitum for 3 h) and the CRF receptor subtype involved. CRF, urotensin...

Dengue has become a major global health threat, especially in tropical and subtropical regions. The development of antiviral agent targeting viral replication is really needed at this time. NS5 methyltransferase presents as a novel antiviral target. This enzyme plays an important role in the methylation of 5'-cap mRNA. Inhibition of the NS5 methyltransferase could inhibit dengue virus replicati...
