MALAT1 and metastatic neoplasm: Initial data-mining studies of publically available databases13–15 showed that three lncRNAs, namely, metastasis-associated lung adenocarcinoma transcript-1 (MALAT1), LOC100190986 and small nucleolar RNA host gene 12 (SNHG12), were expressed at higher levels in PDAC tissues than in normal pancreas tissues and in metastatic tumours than in localized tumours.
