Some of the molecules identified are related to tumor cell chemotaxis (Bradykinin and CXCR4/SDF-1α), preventing vascular regression (angiopoietin-2 and VEGF), GBM proliferation and invasion (interleukin-8 (IL-8), MDGI/FABP3, and inositol-requiring enzyme (IRE)-1α), and the GBM cell–NVU cell interaction (CDC42 and ephrin-B2). This evidence concerns the gene ERN1 and glioblastoma.
