The relative normalized gene expression in liver cells grown as mono and co-cultures. The normalized gene expression of mono-cultured cells grown in the cL-15 media without H₂O₂ supplementation (i.e. the positive control) was set equal to 100 and the other treatments calculated relative to these. The white bars represent the mono cultured cells, while the filled bars represent the co-cultured cells. Differences were assessed by two tailed Mann–Whitney U test and p < 0.05 was accepted as statistically different. Values are mean of 5 fish ± SE. The overall outcome in treatments * conditions (asterisk). Also the within each culture condition treatments effects (letters) are indicated
