As a reference, the expression of the Zta-encoding immediate-early viral gene BZLF1, which is involved in the switch from the latent to the lytic form of EBV infection, and of the lytic genes BLLF1 and BMRF1 showed an opposite response following NF-κB inhibition by PS-1145 (Figure 4E). This evidence concerns the gene NFKB1 and Epstein-Barr virus infection.
