Assays

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).

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

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.
