3D Atlas of the Pituitary Gland of the Model Fish Medaka (Oryzias latipes)

Royan, Muhammad Rahmad; Siddique, Khadeeja; Csucs, Gergely; Puchades, Maja; Nourizadeh-Lillabadi, Rasoul; Bjaalie, Jan G.; Henkel, Christiaan; Weltzien, Finn-Arne; Fontaine, Romain (Peer reviewed; Journal article, 2021)

In vertebrates, the anterior pituitary plays a crucial role in regulating several essential physiological processes via the secretion of at least seven peptide hormones by different endocrine cell types. Comparative and ...

Brain-infecting parasites leave lasting effects on behaviour even in resistant hosts

Vindas, Marco; Midttun, Helene Louise Eghave; Nadler, Lauren Elizabeth; Fontaine, Romain; Weltzien, Finn-Arne; Øverli, Øyvind; Johansen, Ida Beitnes (Peer reviewed; Journal article, 2022)

Data on Western blot and ELISA analysis of medaka (Oryzias latipes) follicle-stimulating hormone (Fsh) and luteinizing hormone (Lh) using recombinant proteins expressed with Pichia pastoris

Burow, Susann; Fontaine, Romain; von Krogh, Kristine; Mayer, Ian; Nourizadeh-Lillabadi, Rasoul; Hollander-Cohen, Lian; Cohen, Yaron; Shpilman, Michal; Levavi-Sivan, Berta; Weltzien, Finn-Arne (Journal article; Peer reviewed, 2019)

The gonadotropins follicle-stimulating hormone (Fsh) and luteinizing hormone (Lh) play essential roles in vertebrate reproduction. This article presents data on molecular weight validation of recombinant medaka (Oryzias ...

Direct and indirect effects of sex steroids on gonadotrope cell plasticity in the teleost fish pituitary

Fontaine, Romain; Royan, Muhammad Rahmad; von Krogh, Kristine; Weltzien, Finn-Arne; Baker, Dianne (Peer reviewed; Journal article, 2020)

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 ...

Functional divergence of thyrotropin beta-subunit paralogs gives new insights into salmon smoltification metamorphosis

Fleming, Mitchell S.; Maugars, Gersende Marie Aimee; Lafont, Anne-Gaëlle; Rancon, Jocelyn; Fontaine, Romain; Nourizadeh-Lillabadi, Rasoul; Weltzien, Finn-Arne; Yebra-Pimente, Elena Santidrian; Dirks, Ron; McCormick, Stephen D.; Rousseau, Karine; Martin, Patrick; Dufour, Sylvie (Journal article; Peer reviewed, 2019)

Smoltification is a metamorphic event in salmon life history, which initiates downstream migration and pre-adapts juvenile salmon for seawater entry. While a number of reports concern thyroid hormones and smoltification, ...

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 ...

Healthy Brain-pituitary Slices for Electrophysiological Investigations of Pituitary Cells in Teleost Fish

Fontaine, Romain; Hodne, Kjetil; Weltzien, Finn-Arne (Journal article; Peer reviewed, 2018)

Electrophysiological investigations of pituitary cells have been conducted in numerous vertebrate species, but very few in teleost fish. Among these, the clear majority have been performed on dissociated primary cells. To ...

Light Pollution Intensity in the Aquatic Environment of the Oslo Area

Medaka (Oryzias latipes) gonadotropins : production and developmental profiles, pharmacological characterization of their receptors, and establishment of a novel transgenic line tg(fshb:DsRed2)

Burow, Susann (PhD Thesis;2019:6, Doctoral thesis, 2019)

The gonadotropins, follicle-stimulating hormone (Fsh) and luteinizing hormone (Lh), produced in gonadotrope cells of the pituitary, possess key roles in the endocrine control of vertebrate puberty and reproduction as part ...

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 ...
