FENDRR and cancer: To the best of our knowledge, from the 12 validated lncRNAs, this is the first study where LANCL1-AS1, LINC01214, LINC01929, NUTM2A-AS1, PCAT19 and SVIL-AS1 are shown to be aberrantly expressed in cancer, while ADAMTS9-AS2, FENDRR, FEZF1-AS1, LINC00673, LINC00968 and PCAT6 have been previously reported to be dysregulated in lung and other types of cancer.
