Fig. 2.
Heat map depicts the regulation of the genes representing DAVID-cluster 1. Red color indicates the highest gene expression and the blue color indicates the lowest gene expression. Gene expression was normalized to the spike-in genes on each array. Each gene is represented by one probe showing approximately the median level of expression across all time points. In all cases the median expression values are similar to the mean values. Asterisks denote genes analyzed by qRT-PCR.
