Abstract
Suppression subtractive hybridization was used to examine gene expression in Atlantic cod head kidney cells treated with polyinosinic polycytidylic acid (poly I:C). One of the most abundant genes was ISG15, showing 24-53% amino acid similarity to ISG15 from both mammals and teleosts. The promoter was cloned by genome walking and three potential interferon-stimulated response elements (ISREs) were identified. Analysis of the gene structure revealed a single intron in the 5' untranslated region (UTR) of cod ISG15, which also seems to be present in zebrafish and pufferfish ISG15. A quantitative real time PCR assay was established to monitor the gene expression of cod ISG15. Injection of cod with poly I:C strongly induced the expression of ISG15 in all organs investigated. Stimulation was most pronounced the first day with a gradual decline the following days. The expression of ISG15 in head kidney cells was also induced in vitro by treatment with poly I:C, but not significantly with LPS. However, injection of formalin killed Vibrio anguillarum-induced ISG15 expression in head kidney.
