Hierarchical clustering of differentially expressed genes in A) pandemic influenza H1N1 and B) seasonal influenza virus infected A549 cells at different post-infection time points. Expression of genes with fold change >+/- 1.5 and p < 0.05 were considered as differentially expressed. Data presented are averaged gene expression changes for 2 different replicates. Black bar indicate expression pattern of immune genes in the two virus infected cells.
