Agonistic and potentiating effects of perfluoroalkyl substances (PFAS) on the Atlantic cod (Gadus morhua) peroxisome proliferator-activated receptors (Ppars)
Söderström, Sofie Karin; Lille-Langøy, Roger; Yadetie, Fekadu; Rauch, Mateusz; Milinski, Ana; Dejaegere, Annick; Stote, Roland H.; Goksøyr, Anders; Karlsen, Odd André (Peer reviewed; Journal article, 2022)Toxicity mediated by per- and polyfluoroalkyl substances (PFAS), and especially perfluoroalkyl acids (PFAAs), has been linked to activation of peroxisome proliferator-activated receptors (Ppar) in many vertebrates. Here, ... -
Environmentally realistic concentrations of chlorinated, brominated, and fluorinated persistent organic pollutants induce the unfolded protein response as a shared stress pathway in the liver of Atlantic cod (Gadus morhua)
Olsvik, Pål Asgeir; Meier, Sonnich; Zhang, Xiaokang; Goksøyr, Anders; Karlsen, Odd André; Yadetie, Fekadu (Peer reviewed; Journal article, 2023)In the North Sea and North Atlantic coastal areas, fish experience relatively high background levels of persistent organic pollutants. This study aimed to compare the mode of action of environmentally relevant concentrations ... -
Integrative omics-analysis of lipid metabolism regulation by peroxisome proliferator-activated receptor a and b agonists in male Atlantic cod
Eide, Marta; Goksøyr, Anders; Yadetie, Fekadu; Gilabert, Alejandra; Bartosova, Zdenka; Frøysa, Håvard Guldbrandsen; Fallahi, Shirin; Zhang, Xiaokang; Blaser, Nello; Jonassen, Inge; Bruheim, Per; Alendal, Guttorm; Brun, Morten; Porte, Cinta; Karlsen, Odd André (Peer reviewed; Journal article, 2023)Lipid metabolism is essential in maintaining energy homeostasis in multicellular organisms. In vertebrates, the peroxisome proliferator-activated receptors (PPARs, NR1C) regulate the expression of many genes involved in ... -
Photo-enhanced toxicity of crude oil on early developmental stages of Atlantic cod (Gadus morhua)
Aranguren Abadía, Libe; Yadetie, Fekadu; Donald, Carey; Sørhus, Elin; Myklatun, Lars Eirik; Zhang, Xiaokang; Lie, Kai Kristoffer; Perrichon, Prescilla; Nakken, Charlotte Langeland; Durif, Caroline; Shema, Steven; Browman, Howard; Skiftesvik, Anne Berit; Goksøyr, Anders; Meier, Sonnich; Karlsen, Odd André (Peer reviewed; Journal article, 2022)Photo-enhanced toxicity of crude oil is produced by exposure to ultraviolet (UV) radiation. Atlantic cod (Gadus morhua) embryos were exposed to crude oil with and without UV radiation (290–400 nm) from 3 days post fertilization ... -
Polycyclic aromatic hydrocarbons modulate the activity of Atlantic cod (Gadus morhua) vitamin D receptor paralogs in vitro
Goksøyr, Siri Øfsthus; Goldstone, Jed; Lille-Langøy, Roger; Lock, Erik Jan Robert; Olsvik, Pål Asgeir; Goksøyr, Anders; Karlsen, Odd André (Peer reviewed; Journal article, 2021)Vitamin D receptor (VDR) mediates the biological function of the steroid hormone calcitriol, which is the metabolically active version of vitamin D. Calcitriol is important for a wide array of physiological functions, ... -
Single PFAS and PFAS mixtures affect nuclear receptor- and oxidative stress-related pathways in precision-cut liver slices of Atlantic cod (Gadus morhua)
Dale, Karina; Yadetie, Fekadu; Horvli, Torill; Zhang, Xiaokang; Frøysa, Håvard G; Karlsen, Odd André; Goksøyr, Anders (Peer reviewed; Journal article, 2022)The aim of the present study was to investigate effects of per- and polyfluoroalkyl substances (PFAS), both single compounds and a mixture of these, using precision-cut liver slices (PCLS) from Atlantic cod (Gadus morhua). ... -
Spawning time in adult polar cod (Boreogadus saida) altered by crude oil exposure, independent of food availability
Strople, Leah Catherine; Vieweg, Ireen; Yadetie, Fekadu; Odei, Derrick Kwame; Thorsen, Anders; Karlsen, Odd André; Goksøyr, Anders; Sørensen, Lisbet; Sarno, Antonio; Hansen, Bjørn Henrik; Frantzen, marianne; Hansen, Øyvind J; Puvanendran, Velmurugu; Nahrgang, Jasmine (Peer reviewed; Journal article, 2023)Fish early life stages are well known for their sensitivity to crude oil exposure. However, the effect of crude oil exposure on adults and their gametes during their spawning period is not well studied. Polar cod, a key ... -
Toxicity assessment of urban marine sediments from Western Norway using a battery of stress-activated receptors and cell-based bioassays from fish
Goksøyr, Siri Øfsthus; Sørensen, Helene; Grøsvik, Bjørn Einar; Pampanin, Daniela Maria; Goksøyr, Anders; Karlsen, Odd André (Peer reviewed; Journal article, 2021)A luciferase reporter gene-based bioassay battery consisting of stress-activated receptors from fish, complemented with traditional fish cell-based bioassays, were used to assess the toxicity of marine sediment samples ... -
Xenobiotic metabolism and its physiological consequences in high-Antarctic Notothenioid fishes
Strobel, Anneli; Lille-Langøy, Roger; Segner, Helmut; Burkhardt-Holm, Patricia; Goksøyr, Anders; Karlsen, Odd André (Peer reviewed; Journal article, 2021)The Antarctic ecosystem is progressively exposed to anthropogenic contaminants, such as polycyclic aromatic hydrocarbons (PAHs). So far, it is largely unknown if PAHs leave a mark in the physiology of high-Antarctic fish. ...
