Vasopressins
Antidiuretic hormones released by the NEUROHYPOPHYSIS of all vertebrates (structure varies with species) to regulate water balance and OSMOLARITY. In general, vasopressin is a nonapeptide consisting of a six-amino-acid ring with a cysteine 1 to cysteine 6 disulfide bridge or an octapeptide containing a CYSTINE. All mammals have arginine vasopressin except the pig with a lysine at position 8. Vasopressin, a vasoconstrictor, acts on the KIDNEY COLLECTING DUCTS to increase water reabsorption, increase blood volume and blood pressure.
Arginine Vasopressin
The predominant form of mammalian antidiuretic hormone. It is a nonapeptide containing an ARGININE at residue 8 and two disulfide-linked cysteines at residues of 1 and 6. Arg-vasopressin is used to treat DIABETES INSIPIDUS or to improve vasomotor tone and BLOOD PRESSURE.
Receptors, Vasopressin
Specific molecular sites or proteins on or in cells to which VASOPRESSINS bind or interact in order to modify the function of the cells. Two types of vasopressin receptor exist, the V1 receptor in the vascular smooth muscle and the V2 receptor in the kidneys. The V1 receptor can be subdivided into V1a and V1b (formerly V3) receptors.
Deamino Arginine Vasopressin
A synthetic analog of the pituitary hormone, ARGININE VASOPRESSIN. Its action is mediated by the VASOPRESSIN receptor V2. It has prolonged antidiuretic activity, but little pressor effects. It also modulates levels of circulating FACTOR VIII and VON WILLEBRAND FACTOR.
Oxytocin
A nonapeptide hormone released from the neurohypophysis (PITUITARY GLAND, POSTERIOR). It differs from VASOPRESSIN by two amino acids at residues 3 and 8. Oxytocin acts on SMOOTH MUSCLE CELLS, such as causing UTERINE CONTRACTIONS and MILK EJECTION.

Vasopressin stimulation of acetate incorporation into lipids in a dimethylbenz(a)anthracene-induced rat mammary tumor cell line. (1/2313)

In a preliminary report we described the effects of rat prolactin on the incorporation of [14C]acetate into lipids by a cell line from a dimethylbenz(a)anthracene-induced rat mammary tumor. The characteristics of the response to prolactin were very similar to those described for the normal rat mammary gland; namely, insulin was required for full expression of the response, maximal activity was not seen until 36 hr after the addition of the hormones, and growth hormone was able to elicit the same response. However, we were unable to detect binding of 125I-labeled prolactin to these cells, and furthermore, other more purified prolactin preparations were inactive. Upon further investigation we discovered that the activity resided in a low-molecular-weight fraction of the rat prolactin B-1 preparation and was probably either vasopressin or oxytocin or both. These data suggest the possibility that vasopressin may play a role in rodent mammary tumorigenesis.  (+info)

Evidence for a vasopressin system in the rat heart. (2/2313)

Traditionally, a hypothalamo-neurohypophysial system is thought to be the exclusive source of arginine vasopressin (AVP), a potent antidiuretic, vasoconstricting, and growth-stimulating neuropeptide. We have identified de novo synthesis of AVP in the heart as well as release of the hormone into the cardiac effluents. Specifically, molecular cloning of sequence tags amplified from isolated, buffer-perfused, and pressure-overloaded rat hearts allowed the detection of cardiac AVP mRNA. Subsequent experiments revealed a prominent induction of AVP mRNA (peak at 120 minutes, 59-fold, P<0. 01 versus baseline) and peptide (peak at 120 minutes, 11-fold, P<0. 01 versus baseline) in these isolated hearts. Newly induced vasopressin peptide was localized most prominently to endothelial cells and vascular smooth muscle cells of arterioles and perivascular tissue using immunohistochemistry. In addition to pressure overload, nitric oxide (NO) participated in these alterations, because inhibition of NO synthase by Nomega-nitro-L-arginine methyl ester markedly depressed cardiac AVP mRNA and peptide induction. Immediate cardiac effects related to cardiac AVP induction in isolated, perfused, pressure-overloaded hearts appeared to be coronary vasoconstriction and impaired relaxation. These functional changes were observed in parallel with AVP induction and largely prevented by addition of a V1 receptor blocker (10(-8) mol/L [deamino-Pen1, O-Me-Tyr2, Arg8]-vasopressin) to the perfusion buffer. Even more interesting, pressure-overloaded, isolated hearts released the peptide into the coronary effluents, offering the potential for systemic actions of AVP from cardiac origin. We conclude that the heart, stressed by acute pressure overload or NO, expresses vasopressin in concentrations sufficient to cause local and potentially systemic effects.  (+info)

Central peptidergic neurons are hyperactive during collateral sprouting and inhibition of activity suppresses sprouting. (3/2313)

Little is known regarding the effect of chronic changes in neuronal activity on the extent of collateral sprouting by identified CNS neurons. We have investigated the relationship between activity and sprouting in oxytocin (OT) and vasopressin (VP) neurons of the hypothalamic magnocellular neurosecretory system (MNS). Uninjured MNS neurons undergo a robust collateral-sprouting response that restores the axon population of the neural lobe (NL) after a lesion of the contralateral MNS (). Simultaneously, lesioned rats develop chronic urinary hyperosmolality indicative of heightened neurosecretory activity. We therefore tested the hypothesis that sprouting MNS neurons are hyperactive by measuring changes in cell and nuclear diameters, OT and VP mRNA pools, and axonal cytochrome oxidase activity (COX). Each of these measures was significantly elevated during the period of most rapid axonal growth between 1 and 4 weeks after the lesion, confirming that both OT and VP neurons are hyperactive while undergoing collateral sprouting. In a second study the hypothesis that chronic inhibition of neuronal activity would interfere with the sprouting response was tested. Chronic hyponatremia (CH) was induced 3 d before the hypothalamic lesion and sustained for 4 weeks to suppress neurosecretory activity. CH abolished the lesion-induced increases in OT and VP mRNA pools and virtually eliminated measurable COX activity in MNS terminals. Counts of the total number of axon profiles in the NL revealed that CH also prevented axonal sprouting from occurring. These results are consistent with the hypothesis that increased neuronal activity is required for denervation-induced collateral sprouting to occur in the MNS.  (+info)

Why is the retention of gonadotrophin secretion common in children with panhypopituitarism due to septo-optic dysplasia? (4/2313)

Septo-optic dysplasia (De Morsier syndrome) is a developmental anomaly of mid-line brain structures and includes optic nerve hypoplasia, absence of the septum pellucidum and hypothalamo-pituitary abnormalities. We describe seven patients (four female, three male) who had at least two out of the three features necessary for the diagnosis of septo-optic dysplasia. Four patients had hypopituitarism and yet normal gonadotrophin secretion: one of these also had anti-diuretic hormone insufficiency; three had isolated GH deficiency and yet had premature puberty, with the onset of puberty at least a year earlier than would have been expected for their bone age. In any progressive and evolving anterior pituitary lesion it is extremely unusual to lose corticotrophin-releasing hormone/ACTH and TRH/TSH secretion and yet to retain gonadotrophin secretion. GnRH neurons develop in the nasal mucosa and migrate to the hypothalamus in early fetal life. We hypothesise that the arrival of GnRH neurons in the hypothalamus after the development of a midline hypothalamic defect may explain these phenomena. Progress in spontaneous/premature puberty in children with De Morsier syndrome may have important implications for management. The combination of GH deficiency and premature puberty may allow an apparently normal growth rate but with an inappropriately advanced bone age resulting in impaired final stature. GnRH analogues may be a therapeutic option. In conclusion, some patients with De Morsier syndrome appear to retain the ability to secrete gonadotrophins in the face of loss of other hypothalamic releasing factors. The migration of GnRH neurons after the development of the midline defect may be an explanation.  (+info)

Comparison of two aquaretic drugs (niravoline and OPC-31260) in cirrhotic rats with ascites and water retention. (5/2313)

kappa-Opioid receptor agonists (niravoline) or nonpeptide antidiuretic hormone (ADH) V2 receptor antagonists (OPC-31260) possess aquaretic activity in cirrhosis; however, there is no information concerning the effects induced by the chronic administration of these drugs under this condition. To compare the renal and hormonal effects induced by the long-term oral administration of niravoline, OPC-31260, or vehicle, urine volume, urinary osmolality, sodium excretion, and urinary excretion of aldosterone (ALD) and ADH were measured in basal conditions and for 10 days after the daily oral administration of niravoline, OPC-31260, or vehicle to cirrhotic rats with ascites and water retention. Creatinine clearance, serum osmolality, ADH mRNA expression, and systemic hemodynamics were also measured at the end of the study. Niravoline increased water excretion, peripheral resistance, serum osmolality, and sodium excretion and reduced creatinine clearance, ALD and ADH excretion, and mRNA expression of ADH. OPC-31260 also increased water metabolism and sodium excretion and reduced urinary ALD, although the aquaretic effect was only evident during the first 2 days, and no effects on serum osmolality, renal filtration, and systemic hemodynamics were observed. Therefore, both agents have aquaretic efficacy, but the beneficial therapeutic effects of the long-term oral administration of niravoline are more consistent than those of OPC-31260 in cirrhotic rats with ascites and water retention.  (+info)

Stimulus-dependent translocation of kappa opioid receptors to the plasma membrane. (6/2313)

We examined the cellular and subcellular distribution of the cloned kappa opioid receptor (KOR1) and its trafficking to the presynaptic plasma membrane in vasopressin magnocellular neurosecretory neurons. We used immunohistochemistry to show that KOR1 immunoreactivity (IR) colocalized with vasopressin-containing cell bodies, axons, and axon terminals within the posterior pituitary. Ultrastructural analysis revealed that a major fraction of KOR1-IR was associated with the membrane of peptide-containing large secretory vesicles. KOR1-IR was rarely associated with the plasma membrane in unstimulated nerve terminals within the posterior pituitary. A physiological stimulus (salt-loading) that elicits vasopressin release also caused KOR1-IR to translocate from these vesicles to the plasma membrane. After stimulation, there was a significant decrease in KOR1-IR associated with peptide-containing vesicles and a significant increase in KOR1-IR associated with the plasma membrane. This stimulus-dependent translocation of receptors to the presynaptic plasma membrane provides a novel mechanism for regulation of transmitter release.  (+info)

Resistance to hepatic action of vasopressin in genetically obese (ob/ob) mice. (7/2313)

1. Fatty acid synthesis, measured in the perfused liver of genetically obese (ob/ob) mice with 3H2O or [14C]actate, did not show the inhibition by [8-arginine]vasopressin (antidiuretic hormone) that is observed in livers from normal mice. 2. Hepatic glycogen breakdown in obese mice was stimuulated by vasopressin, but not as extensively as in lean mice. 3. If obese mice received a restricted amount of food, then fatty acid synthesis still did not respond to vasopressin, but glycogen breakdown was fully stimulated. 4. Cholesterol synthesis was not inhibited by vasopressin in livers from obese mice. 5. Vasopressin inhibited fatty acid synthesis in intact lean mice, but not in obese animals. 6. These results suggest that genetic obesity could be due to an inborn error within the mechanisms (other than adenylate cyclase) which mediate responses to extracellular effectors.  (+info)

Evidence for calcium inactivation during hormone release in the rat neurohypophysis. (8/2313)

1. A study has been made of the relationship between 45Ca uptake into and hormone release from isolated rat neurohypophyses incubated in vitro. 2. Hormone secretion is triggered by high-K (56 mM) but long exposure to the stimulus does not generate a maintained release of hormone. 3. When hormone release began to wane, addition of Ba of La increased hormone output which suggests that the decline in output did not result from depletion of the neurosecretory granules at the nerve terminals. 4. 45Ca uptake is enhanced in the presence of high-K concentration, but the initial high rate declines during long exposure to the potassium stimulus with a time constant similar to that of the decline in hormone release. 5. After a period of incubation in a K-rich, calcium-free medium, addition of calcium to the medium induced hormone release. The magnitude of this release was dependent on the time of exposure to excess potassium. 6.

1. Plasma concentration of arginine vasopressin, plasma osmolality and packed cell volume were measured in stroke-prone spontaneously hypertensive rats (SHRSP) and in normotensive Wistar-Kyoto (WKY) rats at different ages.. 2. In young and in adolescent SHRSP, at 6, 9 and 12 weeks of age, plasma concentration of vasopressin was diminished as compared with age-matched WKY rats (P , 0.01), whereas, in 18-week-old rats, the difference was not significant (P , 0.05). In contrast, in 24-week-old rats, plasma vasopressin was elevated as compared with WKY rats of the same age (P , 0.01).. 3. In none of the age groups did plasma osmolality differ between the two strains of rats, but in all groups packed cell volume in SHRSP was higher than in WKY rats.. 4. During a 48 h period of dehydration, plasma vasopressin concentrations increased similarly in SHRSP and in WKY rats of 6 and 12 weeks of age respectively.. 5.

Role of vasopressin in regulating renal medullary gene expression - University of Arizona
DESCRIPTION (provided by applicant): Diabetes and congestive heart failure are diseases that have been associated with defects in the handling of salt and water by the kidney. Common in individuals with these disorders are elevated circulating levels of vasopressin, the peptide hormone that regulates renal water excretion. Circulating vasopressin plays a critical role in extra-cellular fluid expansion and development of hypertension, thus contributes to the pathogenesis of the disease. Vasopressin has clear long-term actions in the kidney, associated with vasopressin receptor activated processes and transcriptional regulation. Circulating vasopressin also increases the concentrating capacity of the renal medulla by activating the counter current mechanism. The result is an increase in medullary osmotic stress that can directly activate renal cell signaling pathways and gene transcription. Thus specific effects of vasopressin on gene expression are not delineated from secondary alterations ...

Water excretion by the kidney is regulated by the peptide hormone vasopressin. Vasopressin increases the water permeability of the renal collecting duct cells, allowing more water to be reabsorbed from collecting duct urine to blood. Despite long-standing interest in this process, the mechanism of the water permeability increase has remained undetermined. Recently, a molecular water channel (AQP-CD) has been cloned whose expression appears to be limited to the collecting duct. Previously, we immunolocalized this water channel to the apical plasma membrane (APM) and to intracellular vesicles (IVs) of collecting duct cells. Here, we test the hypothesis that vasopressin increases cellular water permeability by inducing exocytosis of AQP-CD-laden vesicles, transferring water channels from IVs to APM. Rat collecting ducts were perfused in vitro to determine water permeability and subcellular distribution of AQP-CD in the same tubules. The collecting ducts were fixed for immunoelectron microscopy ...

THE POSSIBLE MEDIATION BY CYCLIC AMP OF THE STIMULATION OF THYMOCYTE PROLIFERATION BY VASOPRESSIN AND THE INHIBITION OF THIS...
Lysine vasopressin (antidiuretic hormone), like cyclic adenosine 3,5-monophosphate (cyclic AMP), rapidly (in less than 1 hour) stimulates the initiation of deoxyribonucleic acid synthesis and thereby increases the flow of cells into mitosis in rat thymic lymphocyte populations in vitro. This mitogenic action of vasopressin, again like that of cyclic AMP, is potentiated by caffeine, an inhibitor of the intracellular phosphodiesterase which catalyzes the degradation of cyclic AMP. On the other hand, vasopressins mitogenic action (also like that of cyclic AMP) is blocked by imidazole, an activator of cyclic nucleotide phosphodiesterase activity. The hormone, thyrocalcitonin (calcitonin) which is known to block the cyclic AMP-mediated mitogenic effect of parathyroid hormone by interfering with cyclic AMP action, also blocks the mitogenic action of vasopressin. The inhibitory effects of imidazole and thyrocalcitonin on vasopressins mitogenic action are both overcome by the phosphodiesterase inhibitor

Inhospital cardiac arrest still constitutes an important clinical problem with survival to discharge ranging within 0-42% (most common range = 15-20%). Survival after witnessed, pulseless ventricular fibrillation/tachycardia(VF/VT) that is responsive to one or two direct current countershock(s) may exceed 30%. However, survival after inhospital asystole, pulseless electrical activity, or refractory VF/VT (defined as not responsive to two countershocks) may be substantially lower (, 5-10%). As in nonsurvivors, both endogenous vasopressin and adrenocorticotrophin are reduced compared to survivors, we hypothesized that the addition of exogenous vasopressin and steroids to the standard CPR protocol may increase the rates of both the return of spontaneous circulation (ROSC) and of post-arrest survival. The mechanistic basis of this hypothesis comprises the simultaneous activation of adrenergic and vasopressin receptors, in conjunction with a potential steroid-mediated enhancement of the vascular ...

The inhibition of protein synthesis caused by vasopressin was associated with a disaggregation of polysomes, suggesting that peptide chain initiation was slowed relative to elongation. In contrast, Redpath and Proud (Redpath, N. T., and Proud, C. G. (1989) Biochem. J. 262, 69-75) recently reported an inhibition of peptide chain elongation by a calcium/calmodulin-dependent mechanism.

Plasma and platelet vasopressin in essential hypertension and congestive heart failure. | HypertensionPlasma and platelet vasopressin in essential hypertension and congestive heart failure. | Hypertension
In this study we found that, in 31 normal subjects, close to 90% of circulating arginine vasopressin (AVP), measured by radioimmunoassay, was associated with platelets. By using routine methods of centrifugation, which do not completely separate platelets, the normal range of plasma vasopressin was higher by twofold than the normal range in platelet-free plasma prepared by differential centrifugation, which was 1.4 +/- 1.0 sd pg/ml. Platelet vasopressin was 12.9 +/- 5.7 pg/ml. Patients with congestive heart failure had, on average, an elevated platelet-free plasma AVP, as did two patients with thrombocytopenia and one with thrombocytosis. Patients with essential hypertension had slightly high levels of platelet-free plasma AVP and demonstrated an abnormal inverse relationship between platelet-free plasma AVP and serum osmolality. Immunoreactive platelet vasopressin was slightly low in patients with essential hypertension and was subnormal in patients with congestive heart failure. These studies ...

Vasopressin in cardiac surgery. There is limited evidence surrounding the use of vasopressin in cardiac surgery. Anecdotally, we use vasopressin, both during cardiopulmonary bypass and after, when patients have refractory shock. We have no idea what impact this intervention has on outcome. One small (unconvincing) study suggests that the addition of vasopressin is not associated with increased predicted mortality associated with cardiac surgery.27 Specifically, and with scant evidence, vasopressin has been advocated for refractory shock in this setting, especially when there is coexisting pulmonary hypertension.28 In early animal studies, vasopressin was shown to cause pulmonary vasodilation. However, in a well-conducted dog study, vasopressin was shown to cause pulmonary vascular constriction and to exert an important negative inotropic effect on the right ventricle.29 This was not the case when phenylephrine was used to augment systemic BP.29 It may be that at high doses vasopressin causes ...

To investigate whether the kidneys play a critical role in stimulating VP release during hemorrhage in chronic NTS-lesioned rats, we examined the effects of removing potential signals arising from the kidneys. In NTS- lesioned rats, nephrectomy or renal denervation, but not captopril injection, markedly attenuated (but did not abolish) hemorrhage-induced VP release. In contrast, none of these manipulations attenuated the VP response in NTS- intact rats. Hemorrhage increased plasma renin activity in control and NTS- lesioned rats, and this response was not altered by renal denervation. ...

Peptide - New World EncyclopediaPeptide - New World Encyclopedia
The neuropeptide Arginine vasopressin (AVP), also known as argipressin or antidiuretic hormone (ADH), is a hormone found in humans. It is mainly released when the body is low on water; it stimulates water reabsorption in the kidneys. It performs diverse actions when released in the brain, and has been implicated in memory formation, aggression, blood pressure regulation, and temperature regulation. Similar vassopressins are found in other mammalian species.. In recent years, there has been particular interest in the role of vasopressin in social behavior. It is thought that vasopressin, released into the brain during sexual activity, initiates and sustains patterns of activity that support the pair-bond between the sexual partners; in particular, vasopressin seems to induce the male to become aggressive towards other males. Evidence for this connection comes from experimental studies on several species which indicate that the precise distribution of vasopressin and vasopressin receptors in the ...

The mRNA encoding vasopressin has recently been documented within the magnocellular hypothalamo-neurohypophyseal projections of the rat such as the median eminence (ME) and the posterior pituitary (PP), suggesting the possibility of its axonal transport. To address the origin of this mRNA and to investigate the functional significance of this unexpected axonal transport of mRNA, we have examined its subcellular localization within both magnocellular perikarya and their axonal projections. For this purpose, we have used nonradioactive in situ hybridization techniques in order to localize the vasopressin mRNA with precision at the ultrastructural level in magnocellular perikarya, dendrites, and axons from control, salt-loaded, and lactating rats. This approach permitted us to demonstrate directly the axonal localization of vasopressin mRNA. Moreover, we were able to obtain novel information concerning vasopressin mRNA compartmentation within both perikarya and axons. At both light and electron ...

JCI - Mechanism of Effect of Hypoxia on Renal Water ExcretionJCI - Mechanism of Effect of Hypoxia on Renal Water Excretion
The effect of lowering the pressure of oxygen from 80 to 34 mm Hg was examined in anesthetized dogs that were undergoing a water diuresis. This degree of hypoxia was associated with an antidiuresis as urine osmolality (Uosm) increased from 107 to 316 mosmol/kg H2O (P < 0.001) and plasma arginine vasopressin increased from 0.06 to 7.5 μU/ml, (P < 0.05). However, hypoxia was not associated with significant changes in cardiac output (CO, from 4.2 to 4.7 liters/ min), mean arterial pressure (MAP, from 143 to 149 mm Hg), glomerular filtration rate (GFR, from 46 to 42 ml/min), solute excretion rate (SV, from 302 to 297 mosmol/min), or filtration fraction (from 0.26 to 0.27, NS). Hypoxia was associated with an increase in renal vascular resistance (from 0.49 to 0.58 mm Hg/ml per min, P < 0.01). The magnitude of hypoxia-induced antidiuresis was the same in innervated kidneys and denervated kidneys. To further examine the role of vasopressin in this antidiuresis, hypoxia was induced in hypophysectomized ...

Integrating cytosolic calcium signals into mitochondrial metabolic responses. | IRIS Università degli Studi di PadovaIntegrating cytosolic calcium signals into mitochondrial metabolic responses. | IRIS Università degli Studi di Padova
Stimulation of hepatocytes with vasopressin evokes increases in cytosolic free Ca2+ ([Ca2+]c) that are relayed into the mitochondria, where the resulting mitochondrial Ca2+ ([Ca2+]m) increase regulates intramitochondrial Ca2+-sensitive targets. To understand how mitochondria integrate the [Ca2+]c signals into a final metabolic response, we stimulated hepatocytes with high vasopressin doses that generate a sustained increase in [Ca2+]c. This elicited a synchronous, single spike of [Ca2+]m and consequent NAD(P)H formation, which could be related to changes in the activity state of pyruvate dehydrogenase (PDH) measured in parallel. The vasopressin-induced [Ca2+]m spike evoked a transient increase in NAD(P)H that persisted longer than the [Ca2+]m increase. In contrast, PDH activity increased biphasically, with an initial rapid phase accompanying the rise in [Ca2+]m, followed by a sustained secondary activation phase associated with a decline in cellular ATP. The decline of NAD(P)H in the face of ...

Derics MindBlog: Vasopressin increases human risky cooperative behaviorDerics MindBlog: Vasopressin increases human risky cooperative behavior
The history of humankind is an epic of cooperation, which is ubiquitous across societies and increasing in scale. Much human cooperation occurs where it is risky to cooperate for mutual benefit because successful cooperation depends on a sufficient level of cooperation by others. Here we show that arginine vasopressin (AVP), a neuropeptide that mediates complex mammalian social behaviors such as pair bonding, social recognition and aggression causally increases humans willingness to engage in risky, mutually beneficial cooperation. In two double-blind experiments, male participants received either AVP or placebo intranasally and made decisions with financial consequences in the Stag hunt cooperation game. AVP increases humans willingness to cooperate. That increase is not due to an increase in the general willingness to bear risks or to altruistically help others. Using functional brain imaging, we show that, when subjects make the risky Stag choice, AVP down-regulates the BOLD signal in the ...

The most pressing concern of any animal that lives in the desert is making sure its body has enough water to carry it through the day. Needless to say, water can be hard to come by in such arid lands, and what water is present is usually found in seeds, tubers, and other plant material. Rodents will find and take in this water, but they face another problem: the contents of their diet are very salty. The rodents must now find a way to get rid of this excess salt while still holding onto a fair amount of water, for they cannot afford to simply excrete a steady stream of urine like we can. They must call upon a chemical from their brain, vasopressin, to help them out with this process. Vasopressin is an antidiuretic hormone, what I like to call an anti-makes-you-pee. It is made in the hypothalamus part of the brain, and when called upon it exits the pituitary gland and travels by blood to the kidneys. Once there, vasopressin causes the tiny blood vessels in the kidneys to clench up, slowing the ...

Abstract: Vasopressin receptor antagonists (vaptans) are a new class of drugs to treat congestive heart failure. Since there are three subtypes of the receptor located in different tissues, it is important to devise tailor-made vaptans to target the appropriate receptor subtype. The binding of three vaptans, OPC21268, mozavaptan and tolvapatan was measured to the human V1-vascular vasopressin receptor (hV1R). Whereas arginine vasopressin (AVP) binds to hV1R and hV2R with equal affinity, vaptans interact differently with the receptor ...

Phosphatidylinositol metabolism in rat hepatocytes stimulated by vasopressin | Biochemical JournalPhosphatidylinositol metabolism in rat hepatocytes stimulated by vasopressin | Biochemical Journal
In isolated rat hepatocytes, vasopressin evoked a large increase in the incorporation of [32P]Pi into phosphatidylinositol, accompanied by smaller increases in the incorporation of [1-14C]oleate and [U-14C]glycerol. Incorporation of these precursors into the other major phospholipids was unchanged during vasopressin treatment. Vasopressin also promoted phosphatidylinositol breakdown in hepatocytes. Half-maximum effects on phosphatidylinositol breakdown and on phosphatidylinositol labelling occurred at about 5 nM-vasopressin, a concentration at which approximately half of the hepatic vasopressin receptors are occupied but which is much greater than is needed to produce half-maximal activation of glycogen phosphorylase. Insulin did not change the incorporation of [32P]Pi into the phospholipids of hepatocytes and it had no effect on the response to vasopressin. Although the incorporation of [32P]Pi into hepatocyte lipids was decreased when cells were incubated in a Ca2+-free medium, vasopressin ...

The aim of this thesis was to determine any association between plasma oxytocin and vasopressin concentrations and renal water and sodium excretion during normal pregnancy. In addition to investigate changes in concentrations of estradiol, progesterone, oxytocin, cortisol, and glucose in the blood before and in the nearest hours after delivery and if treatment with oxytocin affected these concentrations and the fluid balance during the different stages of labour.. Oxytocin, vasopressin, estradiol, progesterone, and cortisol were analysed in blood plasma or serum by radioimmunoassay or ELISA: serum glucose, and osmolality, and sodium in plasma and urine were analysed by standard laboratory techniques.. Fifty-seven women were studied during pregnancy and fifty-one during parturition and post partum. The low plasma vasopressin and increasing plasma oxytocin concentrations with unchanged water and sodium excretion indicate that oxytocin assists vasopressin in concentrating urine during ...

Oxytocin is critical for lactation and maternal care, but oxytocin and the related nonapeptide vasopressin are important for caregiving behaviors in fathers and alloparents as well. This experiment tested the effects of vasopressin and oxytocin on food sharing in marmoset families. We treated caregivers (parents, siblings) with intranasal vasopressin, oxytocin, or saline, and then paired them with the youngest marmoset in the family. Caregivers were given preferred food, and then observed for food sharing and aggressive behavior with young marmosets. Oxytocin reduced food sharing from male alloparents to youngest siblings, and fathers that received vasopressin refused to share food with their youngest offspring more often than when treated with oxytocin. Vasopressin increased aggressive vocalizations directed toward potential food recipients in all classes of caregivers. These results indicate that vasopressin and oxytocin do not always enhance prosocial behavior: modulation of food sharing depends on

Haemodynamic role of vasopressin released during Finnish sauna - edocHaemodynamic role of vasopressin released during Finnish sauna - edoc
The effect of vasopressin released during Finnish sauna on blood pressure, heart rate and skin blood flow was investigated in 12 healthy volunteers. Exposure to the hot air decrease body weight by 0.6 to 1.25 kg (mean = 0.8 kg, P less than 0.001). One hour after the end of the sauna sessions, plasma vasopressin was higher (1.7 +/- 0.2 pg/ml, P less than 0.01 mean +/- SEM) than before the sauna (1.0 +/- 0.1 pg/ml). No simultaneous change in plasma osmolality, plasma renin activity, plasma norepinephrine, epinephrine, cortisol, aldosterone, beta-endorphin and metenkephalin levels was observed. Despite the slight sauna-induced elevation in circulating vasopressin, intravenous injection of the specific vascular vasopressin antagonist d(CH2)5Tyr(Me)AVP (5 micrograms/kg) 1 h after the sauna had no effect on blood pressure, heart rate or skin blood flow. These data suggest that vasopressin released into the circulation during a sauna session reaches concentrations which are not high enough to interfere ...

Background: We had previously shown that vasopressin levels rise by 100-fold with fetal bypass, suggesting a possible role in rising placental vascular resistance seen with fetal cardiac surgery. To test our hypothesis that vasopressin may play a central role in placental dysfunction following fetal bypass, we carried out isolated vessel bath studies with placental vasculature, using vasopressin and selective vasopressin receptor antagonism (V1-a).. Methods: Adult rat aortas (controls) and fourth order ovine placental vessels were harvested and 5 mm rings mounted in temperature controlled aerated Radnoti vessel baths with continuous isometric tension measurement and recording. All vessels were tested with phenylephrine and acetylcholine to demonstrate viability of endothelium and baseline vascular smooth muscle responses. Placental vessels (n=6) and rat aortas (n=8) were exposed to log doses of vasopressin (10−11 to 10−7 g/mL). Placental vessels (n=5) and rat aortas (n=4) were treated with ...

Central vasopressin signalling and aggressive behaviour
Although many signalling molecules appear relevant to the production of complex behaviours, those that are important to the physiological regulation of behaviour, and so those that characterise individual styles of behaviour, are unknown. Vasopressin is the strongest candidate regulator of social behaviour. Experiments were carried out in consideration that vasopressin may directly regulate aggressive behaviour in lactating rats. Patterns of immediate early gene expression during/subsequent to aggressive behaviour suggested specific neural circuits may have significant direct regulatory influence over particular behaviours, and that activation of the V1b vasopressin receptor, in these circuits, may contribute to this putative regulatory signalling. In situ hybridisation studies indicated that patterns of vasopressin release, rather than receptor expression, might be important for any peripartum changes in behaviour driven by vasopressin. Although their relative importance is unknown, central ...

Copeptin - WikipediaCopeptin - Wikipedia
Copeptin (also known as CT-proAVP) is a 39-amino acid-long peptide derived from a pre-pro-hormone consisting of vasopressin, neurophysin II and copeptin. Arginine vasopressin (AVP), also known as the antidiuretic hormone (ADH), is involved in multiple cardiovascular and renal pathways and functions. However, vasopressin measurements are not commonly used in clinical practice because of the biochemical features of the molecule: its small size and very short half-life make vasopressin testing quite complicated and labor-intensive. On the other hand, copeptin can be immunologically tested with ease and therefore be used as a vasopressin surrogate. Copeptin is a 39-amino acid-long, glycosylated peptide. It is synthesized mainly in the paraventricular neurons of the hypothalamus and in the supraoptical nucleus. During axonal transport, pre-pro-AVP is proteolytically cleaved into vasopressin, neurophysin II and copeptin. These molecules are then stored in secretory granules in the posterior pituitary ...

Frontiers | Endocrine Disruption of Vasopressin Systems and Related Behaviors | EndocrinologyFrontiers | Endocrine Disruption of Vasopressin Systems and Related Behaviors | Endocrinology
Endocrine disrupting chemicals (EDCs) are chemicals that interfere with the organizational or activational effects of hormones. Although the vast majority of the EDC literature focuses on steroid hormone signaling related impacts, growing evidence from a myriad of species reveals that the nonapeptide hormones vasopressin (AVP) and oxytocin (OT) may also be EDC targets. EDCs shown to alter pathways and behaviors coordinated by AVP and/or OT include the plastics component bisphenol A (BPA), the soy phytoestrogen genistein (GEN), and various flame retardants. Many effects are sex specific and likely involve action at nuclear estrogen receptors. Effects include the elimination or reversal of well-characterized sexually dimorphic aspects of the AVP system, including innervation of the lateral septum and other brain regions critical for social and other non-reproductive behaviors. Disruption of magnocellular AVP function has also been reported in rats, suggesting possible effects on hemodynamics and

Phorbol ester inhibition of the hormone-stimulated phosphoinositide cycle in WRK-1 cells | Biochemical JournalPhorbol ester inhibition of the hormone-stimulated phosphoinositide cycle in WRK-1 cells | Biochemical Journal
WRK-1 rat mammary tumour cells respond to vasopressin with increased accumulation of inositol phosphates as well as increased precursor incorporation into phosphatidylinositol. The phorbol ester, phorbol 13-myristate 12-acetate (PMA) inhibits by 80% both inositol phosphate accumulation and increased precursor incorporation. This inhibition is much less evident at early times (2 min) than at later times (25 min). The vasopressin-induced rise in cytosolic free Ca2+ is inhibited in a similar manner. Oleoylacetylglycerol is inactive with respect to inhibition of vasopressin-induced increases in incorporation of 32P into phosphoinositides. PMA has no effect on vasopressin binding at saturating concentrations of the hormone and does not affect the binding affinity. ...

Inhibition of Renin Release in the Dog by Vasopressin and Vasotocin | Circulation ResearchInhibition of Renin Release in the Dog by Vasopressin and Vasotocin | Circulation Research
In anesthetized dogs the intravenous infusion of arginine vasotocin, 25 mU/min, or vasopressin, 10 mU/min, inhibited renin secretion when control secretion rates were normal or when they were elevated by complete ureteral occlusion. Vasotocin, 5 mU/min, or vasopressin, 1 mU/min, was ineffective. Direct intraarterial infusion of vasotocin, 5 mU/min, into the right kidney inhibited renin secretion by the right kidney only. Glomerular filtration rate and renal plasma flow were not changed, and mean arterial pressure was either not changed or was decreased. Vasotocin caused no change in urine flow but did produce a significant natriuresis secondary to decreased tubular reabsorption.

We appreciate the comments from Dr. Jha. According to the study protocol, all patients received a cardiac output monitor aiming to optimize fluid status and cardiac index. Therefore, as our data show, with norepinephrine or vasopressin, we did not observe either a reduction in the cardiac index or a worsening of tissue perfusion and oxygenation parameters as lactate and central venous oxygen saturation.1 Furthermore, the incidence of low cardiac output and cardiogenic shock in the norepinephrine and vasopressin groups was not different. We attribute this to the fact that we assessed the fluid status and used inotropes regularly, in accordance with an established protocol of care. Dobutamine is our inotrope of choice in vasoplegic syndrome because both levosimendan and milrinone have inherent vasodilating properties that result in hypotension in these cases. In the Vasopressin and Septic Shock Trial (VASST) substudy, Gordon et al. showed similar effects of both vasopressin and norepinephrine in ...

The objective of this review is to summarise current research in the use of three different vasopressors for cardiopulmonary arrest. Both experimental and clinical studies from human and veterinary literature are employed to assess the efficacy of these vasopressors and to recognise potential for current use of the drugs in veterinary emergency medicine. Adrenaline is the most effective vasopressor available, however, high doses of adrenaline are detrimental to the post-resuscitative period. The use of methoxamine avoids some of the adverse effects of adrenaline but its efficacy as an adequate vasopressor for cardiopulmonary and cerebral resuscitation is questionable. Although vasopressin has been shown to be superior to adrenaline in many recent laboratory studies, clinical research evidence for the use of vasopressin in cardiopulmonary arrest is inadequate.. ...

The Supraoptic Nucleus as an Osmoreceptor - ScienceOpenThe Supraoptic Nucleus as an Osmoreceptor - ScienceOpen
This Progress review is written to challenge the prevalent belief that neurones of the supraoptic nucleus are not involved in the reception of osmotic stimuli. Evidence is presented that these neurones are depolarised by physiological increases in the osmotic pressure of the extracellular fluid. However, generation of action potentials in these depolarised cells still requires the presence of synaptic input from currently unidentified neurones. We suggest that the osmoreceptor regulating vasopressin secretion is probably composed of more than one type of neurone and discuss this suggestion in the context of selected experiments previously cited as evidence that the supraoptic nucleus is not involved in osmoreception.

OBJECTIVES Although latest advances have led to a better understanding of the beneficial effects of vasopressin on haemodynamics in paediatric cardiac surgery LY170053 not much information is available on the adverse effects. or diastolic arterial blood pressures heart rate or inotropic score upon admission to the intensive LY170053 care unit were observed between the groups. No adverse effects on the aminotransferase amounts were noticed. The vasopressin (+) group got higher urea and creatinine amounts. All of the patients except for one received peritoneal dialysis about the entire day of surgery. Thirteen individuals in the vasopressin (+) group and 7 individuals in the vasopressin (?) group continuing to need peritoneal dialysis on postoperative day time 5 (POD 5) ([1]. Postoperative medical parameters assessed had been mortality the space of ICU stay as well as the duration of mechanised ventilation. Due to the retrospective character of the scholarly research individual consent was waived ...

Cognition and hydration in warmer climates · The UKs leading Sports Psychology WebsiteCognition and hydration in warmer climates · The UKs leading Sports Psychology Website
The human body constitutes approximately 60% water which is a key component of every cell contained within it. Hydration is key to keeping performance optimal in any environment but especially in hot climates when physiological systems work maximally to maintain bodily function and output. Exercising increases breathing and heart rate as well as the production of the hormone vasopressin from the pituitary gland, aiding water regulation and retention. Vessels close to the skin dilate and blood flow is directed away from none-essential organs towards the skin, raising sweat production to aid thermoregulation. In heat, these mechanisms are working at an optimal pace as the body is placed under increased stress.. Concentration is the ability to focus the mind on a task and is required when participating in any sport, particularly at elite levels during a major tournament. Tactical and technical decisions are made requiring split-second judgements - some consciously and others from the ingrained ...

CARDIOVASCULAR and vasopressin (A VP) responses to hcmorrhagc wcrc studicd in rats with lesions of the hypothalamic supraoptic nuclei (SONL). Bleeding caused hypotension and increase in heart rate (HR) and A VP. SONL rats failed to fully recover from bleeding as compared to normal rats. Plasma A VP in SONL rats was in the normal in basal conditions, but failed to increase to levels attained in normal rats throughout the post-hemorrhage period. These data suggcst that the supraoptic nuclei are the primary regulatory sitcs for A VP release in rcsponse to hemorrhage and that lack of adequate A VP release significantly retards blood pressure recovery after bleeding ...
