We quantified their upregulation using three separate blots (raw images are shown as Supplementary Figure 7) as pSTAT1 above and found that the IAV-induced expression of viperin polypeptide was further enhanced in NAA60-depleted cells by a significant 4.2-fold (P=0.014), 4.6-fold (P=0.007) and 2.5-fold (P=0.045) at 6 h, 12 h and 24 h post-infection, respectively, compared to control cells (Figure 6B). This evidence concerns the gene NAA60 and infection.
