Distribution of differentially expressed genes among biochemical pathways.

*Pathways containing at least 4 differentially expressed genes (or 8%). Underlined pathways are referred to in the results section.**Percentage of the differentially expressed genes which share a pathway membership with regard to all pathway-associated genes according to Reactome/Biocarta and Kegg pathway databases implemented in Cytoscape 2.7.0.***Differentially expressed genes with shared pathway memberships. Differentially expressed genes with at least 1.5-fold altered expression compared to non-infected control cells and having valid expression signals in at least 4 out of 6 microarray experiments were considered for pathway mapping. Genes showing temporal expression pattern, as depicted in figure 1 B and C, were also included in the analysis.
