MALAT1 and non-small cell lung carcinoma: In our study, GEM may have induced statistically significant downregulation of MALAT1 in the CALU6 NSCLC cell line (p = 0.0363), whilst DOC may have induced statistically significant upregulation of MALAT1 in both LUSC cell lines H1703 and H520 (p = 0.0443 and p = 0.0055, respectively).
