Hydrins, hydroosmotic neurohypophysial peptides: osmoregulatory adaptation in amphibians through vasotocin precursor processing.
Proc. Natl. Acad. Sci. U. S. A. 86 , 5272-5275, (1989) From neurointermediate pituitary glands of Xenopus laevis and Rana esculenta, previously unreported peptides termed hydrins, active on water permeability of frog urinary bladder and frog skin (Brunn or "water-balance" effect), have been isolated and sequenced... |

Correlation between aquaporin and water permeability in response to vasotocin, hydrin and {beta}-adrenergic effectors in the ventral pelvic skin of the tree frog Hyla japonica.
J. Exp. Biol. 213 , 288-294, (2010) The ventral pelvic skin of the tree frog Hyla japonica expresses two kinds of arginine vasotocin (AVT)-stimulated aquaporins (AQP-h2 and AQP-h3), which affect the capacity of the frog's skin to absorb water. As such, it can be used as a model system for analy... |

Molecular cloning of an anuran V(2) type [Arg(8)] vasotocin receptor and mesotocin receptor: functional characterization and tissue expression in the Japanese tree frog (Hyla japonica).
Gen. Comp. Endocrinol. 132 , 485-498, (2003) In most amphibians, [Arg(8)] vasotocin (VT) has an antidiuretic effect that is coupled to the activation of adenylate cyclase. In contrast, mesotocin (MT) has a diuretic effect and acts via the inositol phosphate/calcium signaling pathway in amphibians. To fu... |

The water-absorption region of ventral skin of several semiterrestrial and aquatic anuran amphibians identified by aquaporins.
Am. J. Physiol. Regul. Integr. Comp. Physiol. 299 , R1150-1162, (2010) Regions of specialization for water absorption across the skin of Bufonid and Ranid anurans were identified by immunohistochemistry and Western blot analysis, using antibodies raised against arginine vasotocin (AVT)-stimulated aquaporins (AQPs) that are speci... |

Adaptive evolution of water homeostasis regulation in amphibians: vasotocin and hydrins.
Biol. Cell 89(5-6) , 283-91, (1997) Volemia and osmolality homeostasis is ensured in vertebrates through neuroendocrine reflexes, involving an afferent neural branch from baro- and osmo-receptors to hypothalamus and an efferent endocrine branch from secretory neurons to target hydroosmotic cell... |

Effects of central vasopressin administration to infant rats.
Eur. J. Pharmacol. 233(1) , 101-7, (1993) The neurohypophyseal peptide hormone arginine-vasopressin functions as a neuropeptide in several brain areas in addition to its role as a posterior pituitary hormone. Several studies indicate that arginine-vasopressin and arginine-vasopressin receptors appear... |

Distinct hydro-osmotic receptors for the neurohypophysial peptides vasotocin and hydrins in the frog Rana esculenta.
Neuropeptides 29(5) , 301-7, (1995) The biological properties of vasotocin, hydrin 1 (vasotocinyl-Gly-Lys-Arg) and hydrin 2 (vasotocinyl-Gly), in particular the hydro-osmotic activities on the frog skin, the frog urinary bladder and the frog kidney, have been compared. Hydrins are as active or ... |

The cardiovascular and renal effects of hydrins and arginine vasotocin in frogs.
Gen. Comp. Endocrinol. 91(1) , 1-7, (1993) Cardiovascular and renal actions of hydrins and arginine vasotocin (AVT) in frogs (Rana tigrina and Rana catesbeiana) were examined in view of their relationships as precursor/prohormone-hormones in the anuran amphibian. In vitro hydrins and AVT respectively ... |

A fluorescent analogue of hydrin 1: a new probe for vasotocin receptors.
Am. J. Physiol. 259(4 Pt 1) , E524-8, (1990) Hydrin 1 is the biosynthetic precursor of vasotocin in Xenopus laevis. We have synthesized deamino and fluorescein analogues of hydrin 1 and characterized their physiological action in the urinary bladder of the toad, Bufo marinus. 1-Deamino-hydrin 1 (d-hydri... |

An additional arginine-vasotocin-related peptide, vasotocinyl-Gly-Lys, in Xenopus neurohypophysis.
Biochim. Biophys. Acta 1176 , 143, (1993) The neurohypophysis of Xenopus and that of Ranidae and Bufonidae contain hydrin 1 (vasotocinyl-Gly-Lys-Arg) and hydrin 2 (vasotocinyl-Gly), respectively. In order to test the aldosterone-releasing activity of arginine vasotocin (AVT) and hydrin 1, purificatio... |
