    • A refined method to monitor arousal from hibernation in the European hamster 

      Fasth Markussen, Fredrik Andreas; Melum, Vebjørn Jacobsen; Hazlerigg, David (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-07)
      Background - Hibernation is a physiological and behavioural adaptation that permits survival during periods of reduced food availability and extreme environmental temperatures. This is achieved through cycles of metabolic depression and reduced body temperature (torpor) and rewarming (arousal). Rewarming from torpor is achieved through the activation of brown adipose tissue (BAT) associated with a ...

    • Regulation of pituitary MT1 melatonin receptor expression by gonadotrophin-releasing hormone (GnRH) and early growth response factor-1 (Egr-1): In vivo and in vitro studies 

      Bae, S-E; Wright, IK; Wyse, C; Samson-Desvignes, N; Le Blanc, P; Laroche, S; Hazlerigg, David; Johnston, JD (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)

    • RNA profiling identifies novel, photoperiodhistory dependent markers associated with enhanced saltwater performance in juvenile Atlantic salmon 

      Iversen, Marianne; Mulugeta, Teshome Dagne; Blikeng, Børge Gellein; West, Alexander Christopher; Jørgensen, Even Hjalmar; Sandve, Simen Rød; Hazlerigg, David (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-08)
      Atlantic salmon migrate to sea following completion of a developmental process known as smolting, which establishes a seawater (SW) tolerant phenotype. Smolting is stimulated by exposure to long photoperiod or continuous light (LL) following a period of exposure to short photoperiod (SP), and this leads to major changes in gill ion exchange and osmoregulatory function. Here, we performed an RNAseq ...

    • Thyroid hormone and seasonal rhythmicity 

      Dardente, Hugues; Hazlerigg, David; Ebling, Francis J.P. (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-02-26)
      Living organisms show seasonality in a wide array of functions such as reproduction, fattening, hibernation, and migration. At temperate latitudes, changes in photoperiod maintain the alignment of annual rhythms with predictable changes in the environment.The appropriate physiological response to changing photoperiod in mammals requires retinal detection of light and pineal secretion of melatonin, ...
