The oncogenic circAGO2 (hsa_circ_0135889) derived from AGO2 gene intron 1 bound to HuR and promoted its export to cytoplasm and binding to mRNA 3′UTR, thus suppressing AGO2-miR interaction and mRNA degradation of multiple oncogenes in gastric cancer cells [64]. Here, ELAVL1 is linked to gastric cancer.
