As for gastric cancer, previous studies exhibit that circ‐MTO1 suppresses its development and progression by regulating microRNA (miR)‐3200‐5p/phosphatidylethanolamine binding protein 1 (PEBP1) axis and miR‐199a‐3p/pro‐apoptotic WT1 regulator (PAWR) axis.22, 23. Here, MTO1 is linked to gastric cancer.
