To identify the deregulated expression of various lncRNAs in gastric cancer, we profiled the expression pattern of 19 lncRNAs, 7 oncogenic (H19, TUG1, CCAT1, HOTAIR, BC032469, NEAT1, FALEC), 2 tumor suppressive (PTENP1-AS, GAS5), 5 associated with cell proliferation (MEG3, AP5M1, LINC00312, NBAT1, POU3F3), 2 metastasis-associated (MALAT1, ZEB2-AS1), 1 apoptotic (PANDA), 1 associated with chemoresistance (UCA1) and 1 with reprogramming (LINCROR) shown to be dysregulated in various human cancers (Supplementary Table 1). The gene discussed is AP5M1; the disease is cancer.
