As the name implies, in the ceRNA mechanism, circRNAs competes with common targets for miRNAs to regulate the expression of targets, which has been verified by many researchers—for instance, circRNA-100876 could promote the metastasis and proliferation of gastric cancer by regulating the MIEN1 expression, and the regulated expression of MIEN1 was achieved by sponging miR-136 (11). This evidence concerns the gene MIEN1 and gastric cancer.
