Project description:The dnd gene is essential for the development of primordial germ cells during early embryogenesis. Temporal silencing of dnd in Atlantic salmon embryos resulted in the loss of gametes and halted further reproductive development, although some males exhibited external signs of maturation. Transcriptome analyses of germ cell-ablated testes and ovaries revealed genes with important roles in reproduction, as well as genes with previously unknown functions in the gonads, for instance, a large set of genes involved in neural system development.
Project description:Untargeted metabolomics data obtained from gut samples from adult Atlantic salmon. Sample (about 200 mg) was transferred into a 1.5 ml tube and eluted with 4x wt/vol of ultra-pure water. After homogenization with a Vortex for 1-2 min the sample was centrifuged at 16.000 g for 10 min. The supernatant was transferred into a spinX centrifuge filter, and centrifuged again (15.000 g/4 C/5 min). The filtrate was collected for LC-MS/MS analysis.
Project description:The Atlantic salmon (Salmo salar) genome contains 10 chitinase encoding genes, but little is known about the function of these chitinases. Three of the chitinase genes have previously been shown to be expressed in the stomach tissue of Atlantic salmon. In the current study we show that the protein products of these genes, the family 18 glycoside hydrolase (GH18) chitinases, Chia.3, Chia.4 and Chia.7 are secreted into the stomach mucosa and are amongst the most abundant proteins in this matrix.
Project description:Salmon alphavirus (SAV) and Moritella viscosa causing respectively pancreatic disease and winter ulcer are among the most important pathogens threatening Atlantic salmon aquaculture. Fish is protected by vaccination with different rate of success. Here, responses to vaccination were assessed followed with pathogen challenges of vaccinated salmon and saline injected control.
