Nonapeptide molecular evolution during the adaptive radiation of Tanganyika cichlids. [PDF]

J Neuroendocrinol
Abstract Oxytocin (OT) and vasotocin (VT) are evolutionarily conserved nonapeptides that regulate a wide range of physiological and behavioral processes in vertebrates. Their receptor families have undergone gene duplications that facilitated functional diversification throughout vertebrate evolution.

Nonapeptide cell size differs between male morphs of the West African cichlid, Pelvicachromis pulcher. [PDF]

J Fish Biol
Abstract Alternative male morphs are found in many species of fishes. These morphs often differ in suites of social behaviours, such as aggression and territoriality, associated with alternative reproductive tactics. Such consistent morph‐typical behavioural profiles suggest common differences in underlying neuroendocrine mechanisms.

Neurohypophysial Hormones Regulate Amphibious Behaviour in the Mudskipper Goby. [PDF]

PLoS ONE, 2015
The neurohypophysial hormones, arginine vasotocin and isotocin, regulate both hydromineral balance and social behaviors in fish. In the amphibious mudskipper, Periophthalmus modestus, we previously found arginine-vasotocin-specific regulation of ...

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

J 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 ...

How inversion variants can shape neural circuitry: Insights from the three-morph mating tactics of ruffs

Frontiers in Physiology, 2022
Behavior polymorphisms underlying alternative mating tactics can evolve due to genetic inversions, especially when inversions capture sets of genes involved in hormonal regulation.

Identification of neurohypophysial hormones and the role of VT in the parturition of pregnant seahorses (Hippocampus erectus)

Frontiers in Endocrinology, 2022
Neurohypophysial hormones regulate the reproductive behavior of teleosts; however, their role in the gestation and parturition of ovoviviparous fishes with male pregnancy (syngnathids) remains to be demonstrated.

Isotocin neuronal phenotypes differ among social systems in cichlid fishes [PDF]

Royal Society Open Science, 2017
Social living has evolved numerous times across a diverse array of animal taxa. An open question is how the transition to a social lifestyle has shaped, and been shaped by, the underlying neurohormonal machinery of social behaviour.

Teleost Nonapeptides, Isotocin and Vasotocin Administration Released the Milt by Abdominal Massage in Male Catfish, Clarias magur

Frontiers in Endocrinology, 2022
In the present work the nonapeptides i.e., isotocin and vasotocin alone or in a combination were tested in C. magur to evaluate their effect on stripping by abdominal massage.

Characterization of the neurohypophysial hormone gene loci in elephant shark and the Japanese lamprey: origin of the vertebrate neurohypophysial hormone genes

BMC Evolutionary Biology, 2009
Background Vasopressin and oxytocin are mammalian neurohypophysial hormones with distinct functions. Vasopressin is involved mainly in osmoregulation and oxytocin is involved primarily in parturition and lactation.
