Supplementary Material

Supplementary Figure 1: Hierarchal clustering with all probes present on the array of the pre- and postoperative samples together with corresponding adjacent normal tissue shows overall similar expression profiles for the majority of the pre- and postoperative tumor pairs.

Supplementary Figure 2: Hierarchical clustering of the samples using the differently expressed genes (FDR < 2.5%) separates the majority of the preoperative tumors from the corresponding postoperative tumors.

Supplementary Figure 3: Molecular network showing the interaction between all the 228 differently expressed genes. The gene identifiers and corresponding expression values were uploaded into in the Ingenuity Pathway Analysis. Networks were then algorithmically generated based on their connectivity in Ingenuity's Knowledge Base. Molecules are represented as nodes, and the biological relationship between two nodes is represented as an edge (line). The intensity of the node color indicates the degree of up- (red) or down- (green) regulation. Nodes are displayed using various shapes that represent the functional class of the gene product.

Supplementary Table 1: Significantly differently expressed genes between pre- and postoperative samples. All probes with FDR < 2.5% ranked according to SAM. Systematic names shown in brackets.
