The aim of the present study was to determine the effect of the long non‑coding RNA (lncRNA) bladder cancer‑associated transcript 1 (BLACAT1) in chemoresistance of non‑small cell lung cancer (NSCLC) cells. Expression of lncRNA BLACAT1, microRNA (miR)‑17, autophagy‑related protein 7 (ATG7), multidrug‑resistance protein 1 (MRP1), and the autophagy‑associated proteins light chain 3 (LC3)‑II/LC3‑I and Beclin 1 were detected using the reverse transcription‑quantitative polymerase chain reaction and western blot analysis. Cell viability was determined using an MTT assay.

Altered miRNA expression in cancer indicates that miRNAs can function as tumor suppressors or oncogenes. MiR-449c downregulation in non-small cell lung cancer (NSCLC) compared with normal lung tissues was investigated in this study.
