Figure 1

Heatmap of differentially expressed genes between CR (n = 9) and NCR (n = 12) samples obtained from supervised hierarchical clustering using Euclidean distances and Ward method. The color indicates the level of mRNA expression: red - higher level of expression, green - lower level of expression, black – no expression changes (each row represents a gene and each column represents a sample). The CR samples were clustered together and clearly separated from NCR samples.
