The highly conserved metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) lncRNA with >8000 bp was first identified as an oncogene in non-small-cell lung cancer (NSCLC) because of its functional role in promoting metastasis via induction of the epithelial–mesenchymal transition (EMT) and its clinical significance in predicting metastasis of early-stage NSCLC [7,8]. Here, MALAT1 is linked to non-small cell lung carcinoma.
