Elevated expression of CtBP1 correlated positively with TAMs infiltration into NSCLC tissues, induced EMT (epithelial‐mesenchymal transition) in NSCLC cells and modulated the activated NF‐κB signalling pathway leading to increase in CCL2 secretion from NSCLC cells, thus promoting TAM recruitment and polarization. The gene discussed is NFKB1; the disease is non-small cell lung carcinoma.
