It has also been shown that methylation of the FBP1 promoter, which can be induced by other pathways such as the nuclear factor-kappa B (NF-κB) pathway, has also been observed in other types of cancer, such as non-small cell lung cancer (NSCLC) [35] and lung adenocarcinoma (LUAD) [32,36,37]. Here, NFKB1 is linked to non-small cell lung carcinoma.
