Long non-coding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), also named as nuclear-enriched abundant transcript 2 (NEAT2), is a highly conserved nuclear non-coding RNA (ncRNA) and is identified as a prognostic biomarker for metastasis and the progression of lung cancer.7 This evidence concerns the gene MALAT1 and lung cancer.
