LINC00900 and neoplasm: We identified 22 lncRNAs (DOCK9-DT, AC046143.1, AC022509.2, MIR181A2HG, AF131215.7, AC055720.2, AC084375.1, LINC02471, DPP4-DT, AL162511.1, HMGA2-AS1, AL031985.3, AC141930.1, AC012038.2, TBILA, AL158206.1, FAM111A-DT, LINC02454, AC254633.1, AC005479.2, AC007255.1 and LINC00900) that were shared by three lncRNA sets, and these 22 lncRNAs were defined as prognostic differentially expressed FRLs between normal and tumor tissues (Fig. 2A–D).
