FIG 4.

Fold regulation of selected genes related to NF-κB signaling in human lung epithelial cells following influenza virus infection. Calu-3 cells were infected with virus at an MOI of 1. Total RNA was isolated in triplicate from cells at 24 h p.i. and examined by NF-κB array analysis. Selected genes (n = 61) that were significantly (P < 0.05) upregulated (red) or downregulated (green) (>3-fold) in infected cells compared with uninfected cells are shown using the hierarchical analysis of log₂ transformation of fold change. The data can be found in Table S2 in the supplemental material.
