The enrichment analysis of differential gene expression (microarray) data. The distributions for the top twelve canonical maps and GO processes represented by the up-regulated (A, B) and down-regulated (C, D) genes in the combined data set. Individual sector areas reflect relative gene representation of each process/map among the top 12 shown. Processes and pathway maps were prioritized by p-value; the p-value range for maps and GO processes is color-coded. Bolded processes scored in the top 12 in both data sets.
