In the gliomas with EGFR amplification, we confirmed the overexpression of genes implicated in proliferation (CCNB1, CDK2), extracellular matrix remodeling (PLAT, POSTN), immune response (GBP1), cancer stem cell signaling (IQGAP1) as well as several genes known to be highly expressed in glioblastomas (IGFBP2, CHI3L1, PDPN). The gene discussed is PDPN; the disease is cancer.
