The expression levels of MALAT1 (metastasis associated lung adenocarcinoma transcript 1) and AFAP1-AS1 (actin filament associated protein 1 antisense RNA 1) were both significantly up-regulated, whereas TUG1 (taurine-upregulated gene 1) and HMlincRNA 717 were both down-regulated in non-small cell lung cancer (NSCLC)20. The gene discussed is MALAT1; the disease is non-small cell lung carcinoma.
