Moreover, tumor samples obtain from lung cancer patients revealed high levels of NF-κB activation, which was significantly associated with poor prognosis and tumor stage.[44,45] This is in accordance with a meta-analysis concerning the prognostic significance of NF-κB expression in NSCLC, where Gu et al. showed that high NF-κB expression is positively associated with poor survival outcome of NSCLC patients, suggesting a tumor promotive function of NF-κB. The gene discussed is NFKB1; the disease is non-small cell lung carcinoma.
