Anorectic role of high dietary leucine in farmed Atlantic salmon (Salmo salar L.): Effects on feed intake, growth, amino acid transporters and appetite-control neuropeptides
Lai, Floriana; Comesaña, Sara; Gomes, Ana S.; Flatejord, Daniel; Tolås, Ingvill; Espe, Marit; De Santis, Christian; Hartviksen, Mali B.; Verri, Tiziano; Soengas, Jose L.; Rønnestad, Ivar (Journal article; Peer reviewed, 2023)Leucine has been identified to modulate feed intake and energy homeostasis in fish as in other vertebrates. Under allostatic conditions, energy expenditure may change, and adjustments to the processes that govern the energy ... -
Brain Distribution of 10 cart Transcripts and Their Response to 4 Days of Fasting in Atlantic Salmon (Salmo salar L.)
Kalananthan, Tharmini; Gomes, Ana S.; Lai, Floriana; Tolås, Ingvill; Jordal, Ann-Elise O.; Norland, Sissel; Murashita, Koji; Rønnestad, Ivar (Journal article; Peer reviewed, 2021-10-25)Cocaine- and amphetamine-regulated transcript (CART) has been known to be involved in feeding and energy balance in mammals, acting as an anorexigenic neuropeptide in hypothalamus. In Atlantic salmon, little is known about ... -
Cooperation between subcellular NAD pools in the maintenance of NAD-dependent processes
Tolås, Ingvill (Doctoral thesis, 2018-10-31)Nicotinamide adenine dinucleotide (NAD) is needed as a cofactor in several processes throughout the cell, and its availability is decisive for the activity of many NAD-dependent enzymes. Owing to the membrane barriers in ... -
Impact of long-term fasting on the stomach-hypothalamus appetite regulating genes in Atlantic salmon postsmolts
Kalananthan, Tharmini; Folkedal, Ole; Gomes, Ana S.; Lai, Floriana; Handeland, Sigurd Olav; Tolås, Ingvill; Gelebart, Virginie; Rønnestad, Ivar (Journal article; Peer reviewed, 2023)Atlantic salmon will experience periods of fasting during its lifecycle. In nature, prolonged fasting periods occur owing to seasonal fluctuations in available feeds, migration or in relation to reproduction. In a culture ... -
Regional Expression of npy mRNA Paralogs in the Brain of Atlantic Salmon (Salmo salar, L.) and Response to Fasting
Tolås, Ingvill; Kalananthan, Tharmini; Gomes, Ana S.; Lai, Floriana; Norland, Sissel; Murashita, Koji; Rønnestad, Ivar (Journal article; Peer reviewed, 2021-08-26)Neuropeptide Y (NPY) is known as a potent orexigenic signal in vertebrates, but its role in Atlantic salmon has not yet been fully established. In this study, we identified three npy paralogs, named npya1, npya2, and npyb, ...
