Metastasis-associated lung adenocarcinoma transcript 1 (MALAT-1) is an lncRNA initially shown to become overexpressed in early non-small cell lung carcinoma and was used as a marker for the prognosis of metastasis (Ji et al., 2003; Hutchinson et al., 2007). The gene discussed is MALAT1; the disease is non-small cell lung carcinoma.
