The expression of the immunity- or inflammation-related genes was induced by ERV overexpression in goose primary hepatocytes. The relative expression of ERV and immune-related genes was determined by quantitative PCR. The expression of ERVK25P, DDX41, IFIH1, IFNG, IRF7, and STAT3 in the goose primary hepatocytes transfected with ERVK25P overexpression vectors is presented as the fold change over the control (the hepatocytes transfected with empty vectors), n = 4. ∗,∗∗ denote P < 0.05, 0.01 vs. control, respectively. All of the data are shown as mean ± SEM. Abbreviation: ERV, endogenous retrovirus.
