Neuroendocrine Regulation of Plasma Cortisol Levels During Smoltification and Seawater Acclimation of Atlantic Salmon

open access: yesFrontiers in Endocrinology, 2022
Diadromous fishes undergo dramatic changes in osmoregulatory capacity in preparation for migration between freshwater and seawater. One of the primary hormones involved in coordinating these changes is the glucocorticoid hormone, cortisol.

Oxytocinergic Signaling in Zebrafish: Translational Perspectives for Autism Spectrum Disorder. [PDF]

open access: yesJ Neurochem
Alterations in oxytocin signaling are strongly implicated in the social and cognitive deficits characterizing Autism Spectrum Disorder (ASD) and other neurodevelopmental conditions. However, the precise mechanisms remain unclear. The zebrafish (Danio rerio) has emerged as a powerful translational model due to its evolutionarily conserved oxytocin ...

Brain nonapeptide levels are related to social status and affiliative behaviour in a cooperatively breeding cichlid fish [PDF]

open access: yesRoyal Society Open Science, 2015
The mammalian nonapeptide hormones, vasopressin and oxytocin, are known to be potent regulators of social behaviour. Teleost fishes possess vasopressin and oxytocin homologues known as arginine vasotocin (AVT) and isotocin (IT), respectively. The role of

Fetal Neurohypophyseal Arginine Vasopressin and Arginine Vasotocin in Man and Sheep [PDF]

open access: yesPediatric Research, 1977
Immunoreactive arginine vasopressin (AVP) and arginine vasotocin (AVT) were quantitated in 15 of 17 human fetal pituitary glands early in gestation (11-19 weeks) and in 8 of 9 ovine fetal pituitary glands late in gestation (109-137 days). In 14 of 15 human fetal glands, AVT content exceeded that of AVP.

Patterns of stress response to foreign eggs by a rejecter host of an obligate avian brood parasite

open access: yesEcology and Evolution, Volume 13, Issue 1, January 2023., 2023
Stress‐related signaling has been shown to mediate anti‐parasitic behaviors in avian brood parasite hosts. Here we tested if brood parasite‐like model eggs activated the hypothalamic–pituitary–adrenal (HPA) axis and autonomic nervous system compared with host‐like model eggs.

The neural distribution of the avian homologue of oxytocin, mesotocin, in two songbird species, the zebra finch and the canary: A potential role in song perception and production

open access: yesJournal of Comparative Neurology, Volume 530, Issue 13, Page 2402-2414, September 2022., 2022
Abstract The avian homologue of oxytocin (OT), formerly called mesotocin, influences social behaviors in songbirds and potentially song production. We sought to characterize the distribution of OT peptide in the brain of two songbird species: canaries (Serinus canaria) and zebra finches (Taeniopygia guttata).

Knockdown of sexually differentiated vasopressin expression in the bed nucleus of the stria terminalis reduces social and sexual behaviour in male, but not female, mice

open access: yesJournal of Neuroendocrinology, Volume 34, Issue 9, September 2022., 2022
Several studies point at a sexually differentiated role of vasopressin (AVP) in social behaviour, but precisely which AVP sources are involved is not fully understood. BNST AVP knockdown in male, but not female, mice reduced social approach and communicative behaviors directed toward same‐sex conspecifics, without changing offensive attacks, anxiety ...

Nonapeptides Arginine Vasotocin and Isotocin in Fishes: Advantage of Bioactive Molecules Measurement

open access: yesFrontiers in Marine Science, 2020
The aim of this article is to share with fish physiologists and behaviorists our thoughts and hints regarding the involvement of nonapeptides in various physiological and behavioral processes in fishes and the advantage of measurements of bioavailable ...

Effects of pairing on color change and central gene expression in lined seahorses

open access: yesGenes, Brain and Behavior, Volume 21, Issue 5, June 2022., 2022
Seahorses, a putatively pair‐bonding species, were paired and studied for social communication and changes in gene expression in the brain. Paired seahorses showed coordinated color changes and changes in central gene expression in genes related to metabolics, hormones and cilia. Abstract Social monogamy is a reproductive strategy characterized by pair

Oxytocin variation and brain region‐specific gene expression in a domesticated avian species

open access: yesGenes, Brain and Behavior, Volume 21, Issue 2, February 2022., 2022
Abstract The Bengalese finch was domesticated more than 250 years ago from the wild white‐rumped munia (WRM). Similar to other domesticated species, Bengalese finches show a reduced fear response and have lower corticosterone levels, compared to WRMs. Bengalese finches and munias also have different song types.
