Effects of Melatonin on Anterior Pituitary Plasticity: A Comparison Between Mammals and Teleosts
Ciani, Elia; Haug, Trude M; Maugars, Gersende Marie Aimee; Weltzien, Finn-Arne; Falcón, Jack; Fontaine, Romain (Peer reviewed; Journal article, 2021)Melatonin is a key hormone involved in the photoperiodic signaling pathway. In both teleosts and mammals, melatonin produced in the pineal gland at night is released into the blood and cerebrospinal fluid, providing rhythmic ... -
Gnrh receptor gnrhr2bbα is expressed exclusively in lhb-expressing cells in Atlantic salmon male parr
Ciani, Elia; Fontaine, Romain; Maugars, Gersende Marie Aimee; Rasoul, Nourizadeh-Lillabadi; Andersson, Eva; Bogerd, Jan; von Krogh, Kristine; Weltzien, Finn-Arne (Peer reviewed; Journal article, 2020)Gonadotropin-releasing hormone (Gnrh) plays a major role in the regulation of physiological and behavioural processes related to reproduction. In the pituitary, it stimulates gonadotropin synthesis and release via activation ... -
Gonadotrope plasticity at cellular, population and structural levels: A comparison between fishes and mammals
Fontaine, Romain David; Ciani, Elia; Haug, Trude M; Hodne, Kjetil; Ager-Wick, Eirill; Baker, Dianne; Weltzien, Finn-Arne (Journal article; Peer reviewed, 2019)Often referred to as “the master gland”, the pituitary is a key organ controlling growth, maturation, and homeostasis in vertebrates. The anterior pituitary, which contains several hormone-producing cell types, is highly ... -
Melatonin receptors in Atlantic salmon stimulate cAMP levels in heterologous cell lines and show season‐dependent daily variations in pituitary expression levels
Ciani, Elia; Fontaine, Romain; Maugars, Gersende Marie Aimee; Naama, Mizrahi; Mayer, Ian; Levavi-Sivan, Berta; Weltzien, Finn-Arne (Peer reviewed; Journal article, 2019) -
Neuroendocrine regulation of pituitary gonadotropins during puberty in Atlantic salmon parr with focus on melatonin and Gnrh systems
Ciani, Elia (PhD Thesis;2018:105, Doctoral thesis, 2018)The pituitary gland, gonadotropins, together with neurohormones like gonadotropin-releasing hormone (Gnrh) and melatonin are key players in the control of vertebrate reproduction. In teleosts, despite the numerous studies ... -
The Use of Extracellular Membrane Vesicles for Immunization against Francisellosis in Nile Tilapia (Oreochromis niloticus) and Atlantic cod (Gadus morhua L.)
Mertes, Verena; Kashulin, Alexander; Lagos, Leidy; Ciani, Elia; Colquhoun, Duncan John; Haslene-Hox, Hanne; Sletta, Håvard; Sørum, Henning; Winther-Larsen, Hanne Cecilie (Peer reviewed; Journal article, 2021)Francisellosis in fish is caused by the facultative intracellular Gram-negative bacterial pathogens Francisella noatunensis ssp. noatunensis and Francisella orientalis. The disease is affecting both farmed and wild fish ...
