MALAT1 and osteosarcoma: Long non-coding RNA Metastasis-associated lung adenocarcinoma transcript 1 (MALAT-1), one of the first lncRNAs identified, is overexpressed in osteosarcoma cell lines Saos-2, U2OS and HOS compared with the osteoblast cell line hFOB1.19 (p < 0.05), and is overexpressed in human osteosarcoma tissues [27].
