The angiogenic switch is linked to proneural-to-mesenchymal transition in GBM. (A) Highest differentially expressed genes between invasive (untr) and angiogenic (DN) tumors. (B) Biological processes linked to up- and downregulated genes. (C) Heatmap of Verhaak classification shows that invasive tumors (untr) have a proneural phenotype, while angiogenic (DN) tumors have a mesenchymal phenotype. (D) Transcription factor association to upregulated genes (DN). untr = untransduced EGFR amplified cells.
