Analysis of immunoglobulin and T cell receptor gene expression in ballan wrasse (Labrus bergylta) revealed an extraordinarily high IgM expression in the gut
Bilal, Sumaira; Lie, Kai Kristoffer; Dalum, Alf Seljenes; Karlsen, Odd Andre; Hordvik, Ivar (Journal article; Peer reviewed, 2019)The serum IgM concentration of ballan wrasse is relatively high, estimated to approximately 13 mg/ml in adult wild fish of 800 g. The present study revealed an unusual high abundance of IgM mRNA in the gut of ballan wrasse. ... -
Effects of Agricultural Pesticides in Aquafeeds on Wild Fish Feeding on Leftover Pellets Near Fish Farms
Olsvik, Pål Asgeir; Larsen, Anett Kristin; Berntssen, Marc; Goksøyr, Anders; Karlsen, Odd Andre; Yadetie, Fekadu; Sanden, Monica; Kristensen, Torstein (Others, 2019)Screening has revealed that modern-day feeds used in Atlantic salmon aquaculture might contain trace amounts of agricultural pesticides. To reach slaughter size, salmon are produced in open net pens in the sea. Uneaten ... -

Expression and localization of the aryl hydrocarbon receptors and cytochrome P450 1A during early development of Atlantic cod (Gadus morhua)
Aranguren Abadía, Libe; Donald, Carey; Eilertsen, Mariann; Gharbi, Naouel; Tronci, Valentina; Sørhus, Elin; Mayer, Philipp; Nilsen, Tom Ole; Meier, Sonnich; Goksøyr, Anders; Karlsen, Odd Andre (Peer reviewed; Journal article, 2020)The aryl hydrocarbon receptor (Ahr) is a ligand-activated transcription factor that mediates the toxicity of dioxins and dioxin-like compounds (DLCs) in vertebrates. Two clades of the Ahr family exist in teleosts (Ahr1 and ... -
Proteomics and lipidomics analyses reveal modulation of lipid metabolism by perfluoroalkyl substances in liver of Atlantic cod (Gadus morhua)
Dale, Karina; Yadetie, Fekadu; Müller, Mette Helen Bjørge; Pampanin, Daniela Maria; Gilabert, Alejandra; Zhang, Xiaokang; Tairova, Zhanna; Haarr, Ane; Lille-Langøy, Roger; Lyche, Jan Ludvig; Porte, Cinta; Karlsen, Odd Andre; Goksøyr, Anders (Peer reviewed; Journal article, 2020)The aim of the present study was to investigate effects of defined mixtures of polycyclic aromatic hydrocarbons (PAHs) and perfluoroalkyl substances (PFASs), at low, environmentally relevant (1× = L), or high (20× = H) ...
