In recent, LncRNA nicotinamide nucleotide transhydrogenase-antisense RNA1 (NNT-AS1), located in the chromosome 5p12 region, has been reported to be highly expressed in drug-resistant NSCLC tissues and cells, and promote the resistance of NSCLC cells to DDP through the MAPK/Slug signaling pathway [13], indicating NNT-AS1 may be related to DDP-resistant. Here, SNAI2 is linked to non-small cell lung carcinoma.
