Similarly, miR-206 was commonly downregulated among c-Myc and AKT/Ras-oncogene induced HCC mouse models, HCC cell lines, and human HCCs contributing to tumor development and progression through cell cycle regulator cyclin D1 (CCND1), c-MET, and cyclin-dependent kinase 6 (CDK6) direct targeting, as demonstrated by in vitro and in vivo experiments [21]. This evidence concerns the gene MET and hepatocellular carcinoma.
