Moreover, RIP assays demonstrated that hsa_circ_0004913 could be enriched in TARDBP IP samples (Figure 7C) and RNA pull down assays also confirmed that hsa_circ_0004913 could bind to TARDBP in HCC cells (Figure 7D), which supports the existence of TARDBP-hsa_circ_0004913 complex. This evidence concerns the gene TARDBP and hepatocellular carcinoma.
