As expected, 10 μM Gefitinib significantly inhibited the activation of EGFR induced by virus infection at 36 hpi (Figure 3B) Relative to the DMSO control, 10 μM Gefitinib had no observable effects on virus replication at 24 hpi, but at 36 and 48 hpi the virus titers were reduced by approximately 1.4- and 1.7-logs, respectively (Figure 3C). This evidence concerns the gene EGFR and viral infectious disease.
