When evaluating between GBM cell lines and brain tumor tissue, we found that cellular response to heat shock terms were overrepresented in correlated genes, while terms related to immune response (e.g., NF‐kappaB complex, Innate Immune System, Neutrophil degranulation) were overrepresented in anticorrelated genes (Figure 5C and Table S5). This evidence concerns the gene NFKB1 and brain neoplasm.
