Summary: Our study demonstrated differential expression of arginine vasotocin (avt) and isotocin (it) in the brain and pituitary of black porgy during osmotic stress. These findings suggest the involvement of neurohypophysial hormones in the response to osmotic stress.

Summary: The study indicates that oxytocin and vasopressin are adjacent paralogous genes that likely resulted from a local duplication through DNA transposable elements near the origin of vertebrates, with vasotocin retaining more of the parental sequence. Six major oxytocin-vasotocin receptors were identified among vertebrates, potentially originating from a single receptor shared with the common ancestor of invertebrates through whole-genome and large segmental duplications.

Summary: Recent studies have found that exposure to bisphenol S (BPS) can have multiple adverse effects on organisms. This study exposed adult female zebrafish to environmentally relevant concentrations of BPS and found that maternal exposure affected the social behavior and anxiety response of male offspring in a dose-specific manner. The impaired social behavior was associated with changes in neuropeptide signaling pathways in the brain.

Summary: Research shows that in agonistic interactions, dominant rainbow trout exhibit higher aggression and feeding levels, while subordinate fish show upregulation of AVT receptors, CRF mRNA, and cortisol levels.

Summary: This study reveals the impact of social isolation on the oxytocinergic circuit in the zebrafish brain and how chemical signals from conspecific animals modulate this circuit. The results provide a model for understanding how social stimuli mediate adaptive behaviors through neural circuits.

Summary: We identified the precursor and two receptors for Aplysia vasopressin-like peptide (apVT) through various research methods. Post-translational modifications (PTMs) and individual residue substitutions were found to play important roles in receptor activity. The findings provide insights into the Aplysia vasotocin signaling system.

Summary: Recent data suggests that patients with diabetes insipidus (DI) are being harmed. The authors propose renaming central and nephrogenic DI as arginine vasopressin deficiency and resistance, respectively.

Summary: This study investigates the regulation of cortisol and the neuroendocrine mechanisms controlling osmoregulation in Atlantic salmon during migration. It is found that cortisol levels increase during the smoltification period and the factors responsible for regulating the HPI axis and cortisol levels remain unclear. Seasonal changes in cortisol levels and transcript abundance of regulatory genes are evaluated, revealing higher cortisol levels in migratory smolts and differences in gene expression between smolts and pre-migratory parr.

Summary: This article critically reviews the current knowledge of the roles of nonapeptide systems in teleost reproduction, focusing on the roles of arginine vasopressin (AVP) and oxytocin (OXT) in reproductive behavior and the regulation of the hypothalamic-pituitary-gonadal axis. The article also highlights the importance of a gonadal nonapeptide system in steroidogenesis and gamete maturation, and calls for translational studies linking this knowledge to aquaculture, conservation biology, and ecotoxicology.

Summary: Birds are unique among vertebrates in their ability to concentrate urine, with various aquaporins responsible for this process. Different subfamilies of AQPs in birds play distinct roles in water conservation, and recent studies have shown the expression of multiple AQPs in bird kidneys, highlighting their significance in water balance regulation.

Summary: This study provides a parsimonious explanation for the origin of the OTR/VTR gene family, based on phylogenetic and chromosomal conserved synteny analyses. The findings suggest a chromosome quadruplication event associated with whole-genome duplications early in vertebrate evolution, prior to the radiation of jawed vertebrates. The evolution of the OTR/VTR gene family can be explained by two whole-genome duplications followed by differential gene losses of VTR2 genes in different lineages.

Summary: 'Urban adapter' species in urban habitats often display higher aggression towards conspecifics, and this behavior could be regulated by the neuroendocrine system. In this study, it was found that urban male song sparrows had a higher proportion of activated AVT neurons compared to rural males, regardless of the duration of social challenge. These findings suggest that the AVT system plays a role in regulating behavioral responses to urbanization.

Summary: The objective of this study was to evaluate the effect of visual isolation and oxytocin on the aggressive behavior of male Betta splendens. The results showed that visual isolation had no effect on aggression, while exposure to oxytocin reduced the frequency of aggressive behavior.

Summary: The study found that rapid activation of CRH mRNA in the nucleus of hippocampal commissure may play a significant role in avian stress response, potentially different from CRH neurons in the PVN. Results suggest a regulatory role of BDNF in the negative and positive feedback between CRH and CRHR1 in different brain regions.
