Functional analyses of circCSNK1G1 (hsa_circ_101555, hsa_circ_0001955) point that it competes with miR-597-5p or miR-455-3p to regulate the expression of CDK6 (cyclin-dependent kinase 6) and RPA3 (Replication Protein A3) or MYO6 (Myosin VI) genes, all undisputed oncogenes in CRC [183,184]. This evidence concerns the gene MYO6 and colorectal carcinoma.
