Several lncRNAs such as KRTAP5-AS115, nuclear factor-κB-interacting lncRNA16, PNUTS17, gallbladder cancer-associated suppressor of pyruvate carboxylase GCASPC18, and metastasis-associated lung adenocarcinoma transcript 1 (MALAT1)19 have been validated recently as competing endogenous RNAs (ceRNAs) of miRNAs or mRNAs, and regulate gene expression in multiple cancers, including GC. The gene discussed is MALAT1; the disease is gastric cancer.
