Exposure to cold temperatures differentially modulates neural plasticity and stress responses in post-smolt Atlantic salmon (Salmo salar)
Tang, Patrik Anthony; Stefansson, Sigurd Olav; Nilsen, Tom Ole; Gharbi, Naouel; Lai, Floriana; Tronci, Valentina; Vigo, Pablo Balseiro; Marnix, M.; Ebbesson, Lars O.E. (Journal article; Peer reviewed, 2022)The transfer success of farmed post-smolt Atlantic salmon (Salmo salar) to sea-cages rely on neural adaptions to promote stress resilience. As low temperatures impact physiology, this suggests that off-season transfer to ... -
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 (Journal article; Peer reviewed, 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 ... -
Increased Thermal Challenges Differentially Modulate Neural Plasticity and Stress Responses in Post-Smolt Atlantic Salmon (Salmo salar)
Tang, Patrik Anthony; Gharbi, Naouel; Nilsen, Tom Ole; Gorissen, M.; Stefansson, Sigurd Olav; Ebbesson, Lars O.E. (Journal article; Peer reviewed, 2022)The successful transfer of farmed post-smolt Atlantic salmon (Salmo salar) depends on proper stress responses and cognitive functions during the early seawater (SW) phase. However, with increasing summer oceanic temperatures, ... -
New wine in old bottles: Modification of the Na+/K+-ATPase enzyme activity assay and its application in salmonid aquaculture
Takvam, Marius; Sundell, Kristina; Sundh, Henrik; Gharbi, Naouel; Kryvi, Harald; Nilsen, Tom Ole (Journal article; Peer reviewed, 2023)The Na+, K+ ATPase (NKA) enzyme is important to generate the transmembrane ion gradient in the gills, intestine, and kidneys, hence, is vital for secondary transport of fluids and different solutes in teleosts. Gill NKA ... -
Reduced α-galactosidase A activity in zebrafish (Danio rerio) mirrors distinct features of Fabry nephropathy phenotype
Elsaid, Hassan Osman Alhassan; Furriol, Jessica; Blomqvist, Maria; Diswall, Mette; Leh, Sabine; Gharbi, Naouel; Anonsen, Jan Haug; Babickova, Janka; Tøndel, Camilla; Svarstad, Einar; Marti, Hans Peter; Krause, Maximilian (Journal article; Peer reviewed, 2022)Fabry disease (FD) is a rare genetic lysosomal storage disorder, resulting from partial or complete lack of alpha-galactosidase A (α-GAL) enzyme, leading to systemic accumulation of substrate glycosphingolipids with a broad ... -
Reintroduction of dj-1 in müller cells inhibits retinal degeneration in the dj-1 deficient retina
Gharbi, Naouel; Røise, Dagne; Førre, Jorunn-Elise; Edson, Amanda Jayne; Hushagen, Helena Amalie; Tronci, Valentina; Frøyset, Ann-Kristin; Fladmark, Kari E. (Journal article; Peer reviewed, 2021)The eye is continuously under oxidative stress due to high metabolic activity and reactive oxygen species generated by daily light exposure. The redox-sensitive protein DJ-1 has proven to be essential in order to protect ... -
Sulfate homeostasis in Atlantic salmon is associated with differential regulation of salmonid-specific paralogs in gill and kidney
Takvam, Marius; Denker, Elsa; Gharbi, Naouel; Kryvi, Harald; Nilsen, Tom Ole (Journal article; Peer reviewed, 2021)Sulfate (SO2−4) regulation is challenging for euryhaline species as they deal with large fluctuations of SO2−4 during migratory transitions between freshwater (FW) and seawater (SW), while maintaining a stable plasma SO2−4 ... -
Validating timing of salmon smolt runs obtained by telemetry studies
Hulbak, Magnus Andre; Hanssen, Erlend Mjelde; Lennox, Robert; Salvanes, Anne Gro Vea; Barlaup, Bjørn Torgeir; Gharbi, Naouel; Nilsen, Tom Ole; Vollset, Knut (Journal article; Peer reviewed, 2021)Telemetry tags are increasingly used in management to monitor the migration timing of Atlantic salmon smolts (Salmo salar L.). It has been postulated that (1) effects from tagging and handling may alter migration behaviour, ...
