Constitutive NF‐κB activation controls the expression of tumour progression‐associated proteins which participate in tumour cell growth, anti‐apoptosis, angiogenesis and metastasis.11, 12, 13 In addition, the expression of several DNA repair proteins is also linked to NF‐κB activation.14, 15 Puliyappadamba et al demonstrated that glioblastoma had higher NF‐κB activation compared to normal brain and lower grade glioma.1 The gene discussed is NFKB1; the disease is glioma.
