Heatmaps. Heatmaps displaying the relative expression of the probes significant in the three TTA related contrasts (IC vs. TTAIC, TTA vs. CTR and preTTA vs. CTR. The probes were clustered hierarchical using euclidean distance as indicated by the dendrogram on the side. The color code attached to the dendrogram indicates overlap for the corresponding gene between the 3 contrasts. In the dendrogram of the heatmap for contrast IC vs. TTAIC, the three major clusters are highlighted additionally (lightgrey - cluster.1; grey - cluster.2; darkgrey - cluster.3).
