The results revealed significant expression of circRanGAP1 and miR-27b-3p and not circANRIL (circular RNA lack AGO2 binding), after AGO2 antibody binding experiments (Fig. 3B), suggesting that circRanGAP1 may co-exist with miR-27b-3p by binding to each other in HCC cells. Here, AGO2 is linked to hepatocellular carcinoma.
