The article presents an overview of the comparative distribution, structure and functions of
the nonapeptide hormones in chordates and non chordates. The review begins with a …

In this article, the physiological role of ovarian vasotocin (VT) on fish final oocyte maturation
(FOM) and ovulation is reviewed based on the studies mainly available in the catfish …

The neuronal and neuroendocrine peptides oxytocin (OT) and vasotocin (VT), including
vasopressins, have six cognate receptors encoded by six receptor subtype genes in jawed …

Diadromous fishes undergo dramatic changes in osmoregulatory capacity in preparation for
migration between freshwater and seawater. One of the primary hormones involved in …

The vertebrate nonapeptide families arginine vasopressin (AVP) and oxytocin (OXT) are
considered to have evolved from a single vasopressin-like peptide present in invertebrates …

The arginine vasotocin (AVT)‐V1a receptor mediates critical reproductive behaviors of the
nonapeptide vasotocin in the teleost brain. In this study, we report the molecular …

We previously reported the microarray-based selection of three ovulation-related genes in
zebrafish. We used a different selection method in this study, RNA sequencing analysis. An …

Basic and neutral neurohypophyseal (NH) nonapeptides have evolved from vasotocin (VT)
by a gene duplication at the base of the gnathostome lineage. In teleosts, VT and IT are the …

In the catfish Heteropneustes fossilis, three vasotocin (VT) receptor subtype genes, v1a1,
v1a2, and v2a, were cloned and characterized previously. In the present study, using RNA …

In the present study, in vitro effects of synthetic vasotocin (VT), isotocin (4Ser, 8Ile-oxytocin;
ITb) and the recently cloned IT gene paralog product (8Val-Isotocin, ITa) were studied on the …
