(Master thesis, 2023-08-01)Lumpfish plays an important role in aquaculture, where it is used to combat sea lice infestations among farmed salmon, acting as a biological alternative to chemical and physical treatment. As a relative newcomer to ... -
Elevated sea temperature combined with dietary methionine levels affect feed intake and appetite-related neuropeptide expression in the brains of juvenile cobia (Rachycentron canadum)
(Journal article; Peer reviewed, 2023-07-04)This study aimed to determine the impact of elevated temperature combined with different levels of dietary methionine concentrations on feed intake (FI) and brain expression of selected neuropeptides and one receptor ... -
Structural elements determining NAMPT activity
(Doctoral thesis, 2023-06-20)Nikotinamidadenindinukleotid (NAD) er en hydridbærer involvert i redoksreaksjoner i metabolismen. I tillegg er NAD+ et substrat av enzymer som medierer vitale NAD+-avhengige prosesser, der dinukleotidet spaltes, og frigjør ... -
Effects of the emerging marine aquafeed mycotoxins beauvericin (BEA) and enniatin B (ENNB) in Atlantic Salmon (Salmo salar) – Implications on cellular pathways and functions, and tissue responses
(Doctoral thesis, 2023-06-14)Plantebaserte fôringredienser er en kilde til mykotoksinene enniatin B (ENNB) og beauvericin (BEA) for oppdrettslaks (Salmo salar). Dette har skapt bekymring for fiskehelse og fôrsikkerhet, siden disse mykotoksinene foreløpig ... -
Functional characterisation of polybasic motifs in the nucleolar PtdIns(3,4,5)P3- interacting proteins proliferation-associated protein 2G4 and poly(ADP-ribose) polymerase 1
(Doctoral thesis, 2023-06-13)Fosfoinositid 3-kinase (PI3K)-signalveien er viktig for flere cellulære prosesser, inklusiv celleoverlevelse, proliferasjon og proteinsyntese. Den er godt beskrevet i cytoplasmaet. I tillegg kan fosfatidylinositol ... -
Mesenterial adult stem-like cells as a potential source of germinal and somatic lineages in a sea anemone
(Doctoral thesis, 2023-06-09)Adulte stamceller (ASC) opprettholder vekst og homeostase gjennom hele livet til dyr ved kontinuerlig å tilføre nye celler til organismen. ASC-er har blitt godt karakterisert i vertebrat-, nematode- og insektmodeller, som ... -
Expression and function of the transcription factor Rx in Nematostella vectensis
(Master thesis, 2023-06-02)The development of the central nervous system is highly studied and a comparatively well understood field of neurogenesis. The fundamental aspects of neurogenesis have however mostly been studied in a select few bilaterian ... -
