In vivo II - GW and WY: Effects on cod lipid metabolism

The goal of the dCod-project is to combine the competencies in environmental toxicology, biology, bioinformatics and mathematics across the traditional department boundaries, to create a deeper understanding of cods' adaptations and reactions to stressors in the environment. Building on the thoroughly studies and mapping of the cod genome at UiO and the long research traditions on cod at the Department of Biology at UiB, the dCod project will expand our knowledge with methods based on genomics; ...

Coastal zones and oceans constitute an essential fundament for Norway’s history as well as current economy, providing ecosystem services for fisheries, aquaculture, transport, tourism, and recreation. The petroleum activities in Norwegian waters have been crucial for Norway’s financial growth and in financing the Norwegian welfare state. As the pressure on the oceans continuously increases, both the petroleum industry and the seafood industries have acknowledged that awareness and actions are ...

Liver samples from Atlantic cod males. Total RNA isolated using TRI Reagent (Fekadu Yadetie). Sequencing performed with Illumina Stranded mRNA (sequencing poly-A mRNA) at Genomic Core Facility at UiB/Haukeland (contact person Rita Holdhus).

The data sets are submitted to the ArrayExpress repository, and will be linked here.

Untargeted lipidomics analysis was performed on plasma and liver samples of four male fish from each group (n = 4) at Per Bruheim’s lab at NTNU, Norway, using Liquid Chromatography Hybrid Quadrupole Mass Spectrometry (UPLC-HDMS).

Targeted lipidomic analysis was performed on plasma and isolated liver microsomes of eight male fish from solvent control (Control) and High-Dose groups (n = 8) at Cinta Porte’s lab at CSIC, Spain, using Flow Injection Analysis High-Resolution Mass Spectrometry (FIA-HRMS).

The data is submitted to the MetaboLights repository.

The data is submitted to the PRIDE repository, and will be linked here.

The aim of the exposure was to study the effects of activation of peroxisome proliferator-activated receptors (PPARs) in Atlantic cod (Gadus morhua), by injecting the fish with the compounds WY-14,643 and GW501516. Using luciferase reporter assay in vitro, we have shown that WY-14,643 activate Atlantic cod Ppara1 and Ppara2, while GW501516 activate Ppara1, Ppara2, and Pparb. The experimental set-up was as follows: Immature cod were injected at day 0 and day 4 with either high dose (40 mg/kg ...

Untargeted lipidomics analysis was performed on plasma and liver samples of four male fish from each group (n = 4) at Per Bruheim’s lab at NTNU, Norway, using Liquid Chromatography Hybrid Quadrupole Mass Spectrometry (UPLC-HDMS).

Normalisation: The fraction of each lipid compound among all measured lipids in every sample was calculated and was used in the downstream analysis.
