Core Tip
Core Tip: We observed the low level of circ_0003356 expression in gastric cancer (GC) tissues and cells. Circ_0003356 expression was positively related to GC patient prognosis. Exogenous circ_0003356 overexpression and/or miR-668-3p suppression enhanced apoptosis in GC cells and suppressed GC cell proliferation, migration, invasion, and epithelial to mesenchy-mal transition. The overexpression of circ_0003356 also prevented tumor growth in mice. At the mechansistic level, circ_0003356 was found to interact with the miR-668-3p/SOCS3 axis to impair GC development. Together, we reveal new and important molecular details highlighting circ_0003356 as a novel cancer target.
