• Effects of cholecystokinin (CCK) on gut motility in the stomachless fish ballan wrasse (Labrus bergylta) 

      Le, Hoang Thi My Dung; Lie, Kai Kristoffer; Giroud-Argoud, Justine; Rønnestad, Ivar; Sæle, Øystein (Peer reviewed; Journal article, 2019-06-07)
      Cholecystokinin (CCK) is well-known as a key hormone that inhibits stomach emptying and stimulates midgut motility in gastric species. However, the function of CCK related to gut motility in agastric fish, especially in ...
    • Intestinal function of the stomachless fish, ballan wrasse (Labrus bergylta) 

      Le, Hoang Thi My Dung; Shao, Xinting; Krogdahl, Åshild; Kortner, Trond Moxness; Lein, Ingrid; Kousoulaki, Katerina; Lie, Kai Kristoffer; Sæle, Øystein (Peer reviewed; Journal article, 2019-03-26)
      Little is known about the digestion of nutrients in stomachless (agastric) fishes with short intestines, such as wrasse. This study describes the digestion, absorption and evacuation rates in ballan wrasse (Labrus bergylta) ...
    • Iodine nutrition and toxicity in Atlantic cod (Gadus morhua) larvae 

      Penglase, Samuel; Harboe, Torstein; Sæle, Øystein; Helland, Synnøve; Nordgreen, Andreas Hoel; Hamre, Kristin (Peer reviewed; Journal article, 2013-02-19)
      Copepods as feed promote better growth and development in marine fish larvae than rotifers. However, unlike rotifers, copepods contain several minerals such as iodine (I), at potentially toxic levels. Iodine is an essential ...
    • Loss of stomach, loss of appetite? Sequencing of the ballan wrasse (Labrus bergylta) genome and intestinal transcriptomic profiling illuminate the evolution of loss of stomach function in fish 

      Lie, Kai Kristoffer; Tørresen, Ole K.; Solbakken, Monica Hongrø; Rønnestad, Ivar; Tooming-Klunderud, Ave; Nederbragt, Alexander Johan; Jentoft, Sissel; Sæle, Øystein (Peer reviewed; Journal article, 2018-03-06)
      Background: The ballan wrasse (Labrus bergylta) belongs to a large teleost family containing more than 600 species showing several unique evolutionary traits such as lack of stomach and hermaphroditism. Agastric fish are ...
    • Ossification of Atlantic cod (Gadus morhua) – Developmental stages revisited 

      Sæle, Øystein; Haugen, Trine; Karlsen, Ørjan; van der Meeren, Terje; Bæverfjord, Grete; Hamre, Kristin; Rønnestad, Ivar; Moren, Mari; Lie, Kai Kristoffer (Peer reviewed; Journal article, 2017-02)
      In studies of marine larvae, it is common to use days post-hatch as a developmental reference point. We show that age is a poor measure of morphological and physiological development in Atlantic cod. Therefore, we propose ...
    • Spatial transcription of CYP1A in fish liver 

      Olsvik, Pål A.; Lie, Kai K.; Sæle, Øystein; Sanden, Monica (Peer reviewed; Journal article, 2007-12-05)
      Background: The aim of this work was to study how evenly detoxifying genes are transcribed spatially in liver tissue of fish. Ten Atlantic salmon Salmo salar were intraperitoneally injected with 50 mg/kg of the strong CYP1A ...
    • T cell receptor alpha chain genes in the teleost Ballan wrasse (Labrus bergylta) are subjected to somatic hypermutation 

      Bilal, Sumaira; Lie, Kai Kristoffer; Sæle, Øystein; Hordvik, Ivar (Peer reviewed; Journal article, 2018-05-22)
      Previously, somatic hypermutation (SHM) was considered to be exclusively associated with affinity maturation of antibodies, although it also occurred in T cells under certain conditions. More recently, it has been shown ...
