Glioblastoma tissues within the SVZ region show increased expression of gene sets involved in (epithelial-)mesenchymal transition, angiogenesis, and NF-κB and JAK/STAT3 signaling, compared to tumor tissues from non-SVZ-regions, either from the same SVZ-contacting tumors or from glioblastomas that do not contact the SVZ. This evidence concerns the gene NFKB1 and neoplasm.
