Figure 4From: Response network analysis of differential gene expression in human epithelial lung cells during avian influenza infectionsDifferential expression network between H5N1 and RSV. Response network of differentially expressed genes between H5N1 and RSV. (a) A response network H5N1 versus RSV at 8 h is shown with 54 nodes and 65 interactions. The network was calculated with parameters k = 3 and l = 4.5. (b) A H5N1 versus RSV response network at 24 h is depicted with 53 nodes and 71 interactions. Parameters k = 3 and l = 5 were used for calculation. Color coding is according to Figure 1. Edges with arrows indicate chemical reactions, diamond-shaped edge tips denote activation, circle-shaped tips refer to phorphorylation reactions and non-decorated edges are non-directional interactions by physical binding or by inferrence from the iHOP database (see Additional files 7, 8, 9 and 10).Back to article page
