The abnormal social behaviors of Dio3-/- mice were associated with sexually dimorphic alterations in the physiology of oxytocin (OXT) and arginine vasopressin (AVP), 2 neuropeptides with important roles in determining social interactions.
-
Data suggested that arginine vasopressin in the brain, not spinal cord and peripheral system of spinocerebellar ataxia type 3 mice related with the change of the spatial learning and memory of Morris water maze test.
-
The suprachiasmatic nucleus (SCN)network consists of multiple clusters of cellular circadian rhythms that are differentially integrated by AVP and VIP signaling, depending on the postnatal period
-
These results identify G9a-induced histone methylation at the OXT and AVP promoters in the Basolateral Amygdala as a mechanism for mediating stress-induced lasting behavioral depression and its reversal by exercise.
-
PDZ domain-containing protein Sipa1l1 (signal-induced proliferation-associated 1 like 1) binds to the cytoplasmic PDZ-ligand motif of aquaporin-2 and accelerates its endocytosis in the absence of vasopressin
-
Spatiotemporal profiles of arginine vasopressin (AVP) expression at the pixel level revealed circadian rhythms in the entire area of AVP-positive cells in the suprachiasmatic nucleus, and at least two clusters that showed different circadian oscillations.
-
Results suggest morphological and functional differences among the paraventricular nucleus' subnuclei and complex interactions among Chronic Unpredictable Stress, gonadal hormones and AVP immunoreactivity
-
Autophagy was induced in the AVP neurons subjected to endoplasmic reticulum stress in familial neurohypophysial diabetes insipidus mice.
-
A new role of PcG proteins in priming early-life stress-responsive DNA methylation at the Avp enhancer prior to epigenetic programming.
-
The noradrenaline-nitric oxide pathway, which stimulates the expression of vasopressin, involves free radicals.
-
AVP, via activation of V1 receptors, is able to modulate positively contractile activity of longitudinal muscle of mouse distal colon.
-
Dehydration increased plasma osmolality and vasopressin levels, and suppressed the increase in blood flow induced by neural activity, by the endothelium-dependent vasodilator acetylcholine and the smooth muscle relaxant adenosine.
-
Vasopressin expression in the suprachiasmatic nucleus is independent of Crx (cone-rod homeobox)-regulated photoreceptor systems.
-
This suggests that increased IL-1beta and NO levels may cause significant bioenergetics changes in magnocellular neurons, affecting copeptin expression and compromising AVP synthesis and secretion in the late phase of sepsis.
-
Folate deficiency decreases the circadian amplitude of vasopressin and the clock protein PER2.
-
medial amygdala likely modulates hostile aggressive behavior associated with immediate early gene expression in oxytocin and vasopressin neurons
-
results support the idea that variation in ovarian hormones could be related to individual differences in social recognition, at least partly through modulation of the OT and/or AVP systems, particularly in the DS, LA and MPOA.
-
The data suggested that vasopressin or oxytocin exert a minimal effect on most GABA neurons in the lateral hypothalamus but exert a robust excitatory effect on presumptive GABA cells that contain melanin-concentrating hormone.
-
Results indicate that Inpp5k 5-phosphatase is important for the control of the arginine vasopressin/aquaporin-2 signalling pathway and water transport in kidney collecting ducts.
-
Hypothalamic COX-2 activity was not necessary for enhanced arginine vasopressin expression and secretion in response to water deprivation.
