NF-κB mRNA in cells infected with C4BP treated H1N1, 2 h post-infection was found to be relatively upregulated (~0.3 log10), while a downregulation (~−0.7 log10) of the mRNA was recorded 6 h post-infection when compared to the untreated samples (Figure 7C). This evidence concerns the gene NFKB1 and infection.
