    • Entry into puberty is reflected in changes in hormone production but not in testicular receptor expression in Atlantic salmon (Salmo salar) 

      Schulz, Rüdiger W.; Taranger, Geir Lasse; Bogerd, Jan; Nijenhuis, Wouter; Norberg, Birgitta; Male, Rune; Andersson, Eva (Peer reviewed; Journal article, 2019-06-21)
      Background Puberty in male Atlantic salmon in aquaculture can start as early as after the first winter in seawater, stunts growth and entails welfare problems due to the maturation-associated loss of osmoregulation capacity ...

    • The influence of vgll3 genotypes on sea age at maturity is altered in farmed mowi strain Atlantic salmon 

      Ayllon, Fernando; Solberg, Monica Favnebøe; Glover, Kevin; Mohammadi, Faezeh; Kjærner-Semb, Erik Nordtorp; Fjelldal, Per Gunnar; Andersson, Eva; Hansen, Tom Johnny; Edvardsen, Rolf; Wargelius, Anna (Peer reviewed; Journal article, 2019-05-06)
      Background: In Atlantic salmon in the wild, age at maturity is strongly influenced by the vgll3 locus. Under farming conditions, light, temperature and feeding regimes are known significantly advance or delay age at maturity. ...

    • Lumpfish Cyclopterus lumpus reproduction: Pituitary gene expression, physiological and morphological changes accompanying gonadal maturation 

      Andersson, Eva; Denker, Elsa; Norberg, Birgitta; Schulz, Rüdiger W.; Olausson, Sara; Thorsen, Anders; Stefansson, Sigurd Olav; Imsland, Albert (Journal article; Peer reviewed, 2022)
      Lumpfish is the most important cleanerfish species in Atlantic salmon farming. Detailed information on the gonadal maturation process is a prerequisite for year-round production of juvenile lumpfish. In the present study ...

    • Physical exercise augmented cognitive behaviour therapy for older adults with generalised anxiety disorder (PEXACOG): Study protocol for a randomized controlled trial 

      Stavestrand, Silje Haukenes; Sirevåg, Kristine; Nordhus, Inger Hilde; Sjøbø, Trond; Endal, Trygve; Nordahl, Hans Morten; Specht, Karsten; Hammar, Åsa; Halmøy, Anne; Martinsen, Egil Wilhelm; Andersson, Eva; Hjelmervik, Helene; Mohlman, Jan; Thayer, Julian Francis; Hovland, Anders (Peer reviewed; Journal article, 2019-03-18)
      Background Generalised anxiety disorder (GAD) is a frequent and severe anxiety disorder among older adults. GAD increases the risk of developing other disorders such as depression and coronary heart disease. Older adults ...

    • Sex differentiation in Atlantic cod (Gadus morhua L.): morphological and gene expression studies 

      Haugen, Trine; Almeida, Fernanda F. L.; Andersson, Eva; Bogerd, Jan; Male, Rune; Skaar, Katrine Sandnes; Schulz, Rüdiger W.; Sørhus, Elin; Wijgerde, Tim; Taranger, Geir Lasse (Peer reviewed; Journal article, 2012-06-18)
      Background: In differentiated gonochoristic species, a bipotential gonad develops into an ovary or testis during sex differentiation. Knowledge about this process is necessary to improve methods for masculinizing genetically ...

    • The use of photoperiods to provide year round spawning in lumpfish Cyclopterus lumpus 

      Imsland, Albert; Hangstad, Thor Arne; Jonassen, Thor Magne; Stefansson, Sigurd Olav; Nilsen, Tom Ole; Hovgaard, Peter; Elvegård, Tor Anders; Lindberg, Ken Ståle; Mikalsen, Bjørn; Urskog, Tonje Cecilie; Norberg, Birgitta; Andersson, Eva; Spetland, Frank; Reynolds, Patrick (Peer reviewed; Journal article, 2019)
      In order to provide year round spawning broodstock, lumpfish (initial size 746 g and 24.9 cm) were reared under four different photoperiod regimes from January 2017 to July 2018. One group was reared under simulated natural ...

    • Vgll3 and the Hippo pathway are regulated in Sertoli cells upon entry and during puberty in Atlantic salmon testis 

      Kjærner-Semb, Erik Nordtorp; Ayllon, Fernando; Kleppe, Lene; Sørhus, Elin; Skaftnesmo, Kai Ove; Furmanek, Tomasz; Segafredo, Frida Thyri; Thorsen, Anders; Fjelldal, Per Gunnar; Hansen, Tom Johnny; Taranger, Geir Lasse; Andersson, Eva; Schulz, Rüdiger W.; Wargelius, Anna; Edvardsen, Rolf (Peer reviewed; Journal article, 2018-01-30)
      Vgll3 is linked to age at maturity in Atlantic salmon (Salmo salar). However, the molecular mechanisms involving Vgll3 in controlling timing of puberty as well as relevant tissue and cell types are currently unknown. Vgll3 ...
