Increasing evidences revealed that non‐coding RNAs, particularly lncRNAs and miRNAs, have considerable potential values in improving the diagnostic and therapeutic of GC.25, 26 Researchers have found a large number of lncRNAs in GC development, such as lncRNA HOXC‐AS3,27 LINC012344 and lncRNA‐KRTAP5‐AS1.28 Aberrantly expressed lncRNAs are involved in various malignant cytological behaviours of GC cells. Here, PDS5B is linked to gastric cancer.
