Genes expressed at different levels in HK and liver upon dietary supplementation with Sel-Plex. The Venn diagram shows the genes identified by microarray analysis, differentially expressed in HK and liver from trout fed a diet supplemented with 4 mg Se Kg⁻¹ relative to the group fed a control diet. All the genes presented as up-regulated and down-regulated are significantly altered in expression as tested by one-way ANOVA and Tukey’s HSD multiple comparisons test (p < 0.05 and Benjamini-Hochberg correction) with ≥2 fold change in expression
