Heatmap from the significantly differentially expressed genes with a p < 0.05 (limma adjusted p-value) and a standard deviation > 0.5 over all samples (a). After clustering gene interaction networks were generated from the two resulting gene-expression clusters (b). Coloring of the nodes was done using the mean from TCIG-exposed samples (CS). The heatmap and the interaction networks were generated using Netwalker 1.0 [37, 38]. The lines connecting the nodes represent protein-protein interactions (grey), gene regulatory interactions (dark blue), metabolic reactions (yellow), and reactome interactions (light blue)
