For example, lncRNA HOTAIR promotes gastric cancer metastasis by binding to the epigenetic transcriptional regulator polycomb inhibitor complex 2 (PRC2).21 HOTAIR also regulates cisplatin resistance in GC by acting as a competitive endogenous RNA (ceRNA) of miR‐126.22 In addition, LINC01234 functions as a competing endogenous RNA to regulate CBFB expression by sponging miR‐204‐5p regulates the malignant proliferation of GC.4 Here, CBFB is linked to gastric cancer.
