To be specific, miR‐7 could affect proliferation and migration of NSCLC cells by modulation of ERK/MAPK signalling or mediation of TLR9 signalling.16, 17 The miR‐7/NF‐κB signalling axis also mattered for its modulating the metastatic conditions of gastric cancer cells, so this axis might also be responsible for the aetiology of additional cancers, such as NSCLC.18, 19, 20 In consequence, there could exist a correlation among ciRS‐7, miR‐7, NF‐κB signalling and NSCLC onset. Here, NFKB1 is linked to cancer.
