PDS5B and gastric adenocarcinoma: Our study revealed that ceRNA networks with involvements of the following lncRNAs consist of a number of important mRNAs, indicating the presence of important ceRNA networks in their corresponding cancers: MAGI2-AS3, SNHG15, KCNQ1OT1, SNHG1, and MIR17HG in READ; MAGI2-AS3, KCNQ1OT1, H19, MIR17HG, SNHG1, and MALAT1 in COAD; MAGI2-AS3, KCNQ1OT1, and MIR17HG in STAD; MAGI2-AS3, PVT1, AC005154.1, H19, CCDC18, and SNHG1 in LIHC; MAGI2-AS3, KCNQ1OT1, H19, CIRL-AS1, LINC00707, and LINC00958 in HNSC; and finally TMEM161B-AS1 and AC093010.3 in ESCA (Supplementary Figure S1).
