Hepatic transcriptome profiling indicates differential mRNA expression of apoptosis and immune related genes in eelpout (Zoarces viviparus) caught at Göteborg harbor, Sweden

► Low mRNA expression of genes involved in immune system in fish from a large harbor. ► High mRNA expression of apoptotic and DNA damage genes in fish from a large harbor. ► Results verified in the fish captured four years later at the same sites. ► Potential new biomarkers identified.
