Gene expression in infected SK-N-MC cells. Relative levels of transcripts from HERV-W env, HERV-W gag and IFNB1 in SK-N-MC cells infected with increasing doses of herpes simplex type 1 (A) or influenza A/WSN/33 (B) as compared to uninfected control cell-cultures. Relative levels of transcripts from the US6 gene of herpes simplex type 1 (A) and segment 8 of the influenza A/WSN/33 virus strain (B) were determined in infected cultures. Relative levels of viral transcripts were normalized to those observed in cells infected with the lowest dose of each virus (n controls = 4, n virus = 5).
