Ingenuity pathway analysis of the TNF-α network. A. Ingenuity pathway Analysis network 3 depicting relationships among upregulated genes at the 4 day post-infection. Intensity of the red color indicates the degree of up-regulation. Edges are displayed with various labels that describe the nature of relationship between the nodes: ___ represents direct relationship; ----- represents indirect relationship; →represents acts on. Nodes are displayed using various shapes that represent the functional class of the gene product same as shown Figure 6. B. Serum TNF-α level in the control and the Salmonella infection group at 4 days post infection. C. Real-time PCR results for some targeted genes from the TNF-α network.
