In vertebrates, both neutrophils and mononuclear cells like ... -
Development of anaesthetic protocols for lumpfish (Cyclopterus lumpus L.): Effect of anaesthetic concentrations, sea water temperature and body weight
Skår, Malene W.; Haugland, Gyri Teien; Powell, Mark; Wergeland, Heidrun Inger; Samuelsen, Ole Bent (Peer reviewed; Journal article, 2017-07-05)In recent years, use of lumpfish (Cyclopterus lumpus L.) as cleaner-fish to remove sea-lice have been chosen by many salmon farmers in Europe and Canada as an alternative to medical treatment, which has led to large scale ... -
The Escherichia coli alkA Gene Is Activated to Alleviate Mutagenesis by an Oxidized Deoxynucleoside
Grøsvik, Kristin; Tesfahun, Almaz Nigatu; Muruzábal-Lecumberri, Izaskun; Haugland, Gyri Teien; Leiros, Ingar; Ruoff, Peter; Kvaløy, Jan Terje; Knævelsrud, Ingeborg; Ånensen, Hilde; Alexeeva, Marina; Sato, Kousuke; Matsuda, Akira; Alseth, Ingrun; Klungland, Arne; Bjelland, Svein (Journal article; Peer reviewed, 2020)The cellular methyl donor S-adenosylmethionine (SAM) and other endo/exogenous agents methylate DNA bases non-enzymatically into products interfering with replication and transcription. An important product is 3-methyladenine ... -
Genomic analysis of pasteurella atlantica provides insight on its virulence factors and phylogeny and highlights the potential of reverse vaccinology in aquaculture
Ellul, Rebecca Marie; Kalatzis, Panos G.; Frantzen, Cyril Alexander; Haugland, Gyri Teien; Gulla, Snorre; Colquhoun, Duncan John; Middelboe, Mathias; Wergeland, Heidrun Inger; Rønneseth, Anita (Journal article; Peer reviewed, 2021)Pasteurellosis in farmed lumpsuckers, Cyclopterus lumpus, has emerged as a serious disease in Norwegian aquaculture in recent years. Genomic characterization of the causative agent is essential in understanding the biology ... -
Interleukin-1 ligands and receptors in lumpfish (Cyclopterus lumpus L.): molecular characterization, phylogeny, gene expression and transcriptome analyses
Eggestøl, Håvard Øritsland; Lunde, Harald Sæbø; Knutsen, Tim Martin; Haugland, Gyri Teien (Journal article; Peer reviewed, 2020-04-02)The interleukin (IL)-1 family play a fundamental role as immune system modulators. Our previous transcriptome-analyses of leukocytes from lumpfish (Cyclopterus lumpus L.) showed that IL-1β was among the most highly upregulated ... -
