TreeView image of named genes induced during parallel time course. Genes were ranked by average log2(ratio) over all time courses to look at similarity of induction (the mock time course was filtered for genes induced by the infection protocol), and then clustered. Many NFκB-related and responsive genes form a single cluster, representing 40% (20/50) of the most highly induced genes. Outside the node representing these genes, there are a number of other immune-response-related genes, including small inducible cytokines (SCY) which are also regulated by NFκB. Image contrast is set at log2(ratio) = 3.5, indicating a minimum of 12-fold induction for the brightest red spots. Gray spots indicate missing data.
