Ion transporters and osmoregulation in the kidney of teleost fishes as a function of salinity
Takvam, Marius; Wood, Chris M.; Kryvi, Harald; Nilsen, Tom Ole (Journal article; Peer reviewed, 2021-04-20)Euryhaline teleosts exhibit major changes in renal function as they move between freshwater (FW) and seawater (SW) environments, thus tolerating large fluctuations in salinity. In FW, the kidney excretes large volumes of ... -
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 ... -
Role of the kidneys in acid-base regulation and ammonia excretion in freshwater and seawater fish: implications for nephrocalcinosis
Takvam, Marius; Wood, Chris M.; Kryvi, Harald; Nilsen, Tom Ole (Journal article; Peer reviewed, 2023)Maintaining normal pH levels in the body fluids is essential for homeostasis and represents one of the most tightly regulated physiological processes among vertebrates. Fish are generally ammoniotelic and inhabit diverse ... -
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 ...
