Figure 1From: Host gene expression profiling in influenza A virus-infected lung epithelial (A549) cells: a comparative analysis between highly pathogenic and modified H5N1 virusesHierarchical clustering (A) and k-means clustering (B) of differentially expressed genes of HPAI-H5N1 (A/Chicken/India/WB-NIV2664/2008) infected A549 cells at different post-infection time points. Expression of genes with p < 0.05 and fold change > +/- 1.5 were considered as differentially expressed. Data presented are averaged gene expression changes for 2 different replicates for each time point.Back to article page
