(A) Heatmap of the 119 differentially expressed genes, organized from top to bottom by hierarchical clustering. The color coding corresponds to the z-scores of the intensities. The hierarchical clustering dendrogram is shown to the left, with the horizontal axis indicating the degree of dissimilarity. Twelve clusters (a-l) were defined such that all nodes to the right of the open arrows are considered to be sufficiently similar to each other so as to represent a relatively homogeneous pattern of gene expression. The genes in each of these clusters are listed in Supplemental Table 3. (B) Examples of GO terms for the differentially expressed genes and the corresponding numbers of genes that were up/downregulated by stimulation.
