PARP9 and infection: The log2 fold change of these transcripts was much lower at 28 dpi when compared to 24 hpi (Figure 2D), with highest differences observed for IFIT2, LOC101907799 and CMPK2. In contrast, the log2 fold change for IFI27, PARP9, IFI6, and OAS1Z was comparable or nearly equal during both phases of infection.
