Fig. 3From: Regulatory mechanisms, functions, and clinical significance of CircRNAs in triple-negative breast cancerRegulatory mechanisms of circRNAs in TNBC. a Serving as miRNA sponge to compete endogenous RNA and sequester miRNAs from binding mRNA targets to influence downstream protein translation; b Binding RBPs to block their function (protein decoy), form protein-circRNAs complexes, or be scaffolds for protein–protein interactions; c some circRNAs which contains the IRES could be translated into proteinsBack to article page
