Cloning and expression of kiss2 in the zebrafish and medaka.
Newly discovered kisspeptin (metastin), encoded by the Kiss1/KISS1 gene, is considered as a major gatekeeper of puberty through the regulation of GnRH. In the present study, we cloned a novelExpand

Organization of two independent kisspeptin systems derived from evolutionary-ancient kiss genes in the brain of zebrafish.
Kisspeptins are new actors in the neuroendocrine regulation of reproduction. In vertebrates, the number of kiss genes varies from none to three. Zebrafish have two kiss genes, kiss1 and kiss2, andExpand

Laser-captured single digoxigenin-labeled neurons of gonadotropin-releasing hormone types reveal a novel G protein-coupled receptor (Gpr54) during maturation in cichlid fish.
GPR54 is a novel G protein-coupled receptor speculated to be essential for sexual development. However, its role in the regulation of GnRH types is unknown. To address this issue, we cloned GPR54Expand

Ghrelin gene in cichlid fish is modulated by sex and development.
We have identified the complementary and genomic DNA sequences of the novel growth hormone-releasing peptide, ghrelin, in the cichlid fish (tilapia Oreochromis niloticus). The tilapia ghrelinExpand

Thyroid hormone and estrogen regulate brain region-specific messenger ribonucleic acids encoding three gonadotropin-releasing hormone genes in sexually immature male fish, Oreochromis niloticus.
The present study was undertaken to determine whether T3, estrogen, and 11-ketotestosterone could alter a specific population of GnRH-containing neurons, as indicated by a change in messenger RNAExpand

RFamide peptides as mediators in environmental control of GnRH neurons
Hypothalamic gonadotropin-releasing hormone (GnRH) is a key hormone for reproductive functions in vertebrates and non-vertebrates. Although GnRH neuronal system is regulated by several factors suchExpand

Direct regulation of gonadotropin release by neurokinin B in tilapia (Oreochromis niloticus).
Neurokinin B (NKB) was recently identified as a key regulator of reproduction in mammals and fish. Fish were found to possess a specific novel neurokinin termed NKF. To study the role of NKB/NKF inExpand

Immunocytochemical and Ultrastructural Identification of Pituitary Cell Types in the Protogynous Thalassoma duperrey during Adult Sexual Ontogeny
Abstract Protogynous wrasses (Thalassoma duperrey): females (F), primary males (PM) along with a few terminal-phase males (TM) and sex-changed males (SM), were used to characterize the topographicalExpand

Endocrine and orexigenic actions of growth hormone secretagogues in rainbow trout (Oncorhynchus mykiss).
The effects of growth hormone secretagogues (GHSs) on the teleost somatotropic axis are poorly understood, particularly with respect to insulin-like growth factor-I (IGF-I) and the IGF-bindingExpand
