In the renal collecting duct, vasopressin increases osmotic water permeability (P(f)) by triggering trafficking of aquaporin-2 vesicles to the apical plasma membrane. We investigated the role of vasopressin-induced intracellular Ca(2+) mobilization in this process. In isolated inner medullary collecting ducts (IMCDs), vasopressin (0.1 nm) and 8-(4-chlorophenylthio)-cAMP (0.1 mm) elicited marked...
heart failure (hf) is still a major problem worldwide with high morbidity and mortality rates. the recently developed medication for hf is still incapable of reducing its morbidity and mortality, and clinical data supporting the efficacy and safety of its mainstay therapy remain insufficient. arginine-vasopressin (avp) plays important roles in circulatory and water homeostasis, one of which is ...
Biotinyl analogues of [Arg8]vasopressin were synthesized with the biotinyl moiety at position 4. This involved the substitution of 2, 4-diaminobutyric acid (Dab) for Gln4 in [1-deamino-Arg8]vasopressin to give the parent peptide des-[Dab4,Arg8]vasopressin. Two biotinyl analogues with different spacers between the side chain of Dab4 and the biotinyl residue were then prepared and characterized i...
Arrestins have been shown to facilitate the recruitment of G protein-coupled receptors to the clathrin-coated vesicles that mediate their internalization. After (8)Arg-vasopressin-induced internalization, the human V2 vasopressin receptor failed to recycle to the cell surface, whereas the vasopressin type 1a receptor (V1a) subtype did. The possibility that the lack of recycling could identify a...
FE 202158, ([Phe(2),Ile(3),Hgn(4),Orn(iPr)(8)]vasopressin, where Hgn is homoglutamine and iPr is isopropyl), a peptidic analog of the vasoconstrictor hormone [Arg(8)]vasopressin (AVP), was designed to be a potent, selective, and short-acting vasopressin type 1a receptor (V(1a)R) agonist. In functional reporter gene assays, FE 202158 was a potent and selective human V(1a)R agonist [EC(50) = 2.4 ...
We previously reported that a deficiency in the vasopressin V1a receptor (V1aR) results in type 4 renal tubular acidosis, which suggests that vasopressin exerts direct effects on the physiological actions of aldosterone. We investigated the role of vasopressin for nucleocytoplasmic transport of mineralocorticoid receptor (MR) in the intercalated cells. Vasopressin V1aR-deficient (V1aR(-/-)) mic...
