MicroRNA-26a is a key regulon that inhibits progression and metastasis of c-Myc/EZH2 double high advanced hepatocellular carcinoma
The transcription factor c-Myc is a key driver for hepatocellular carcinomas (HCCs), while the polycombrepressive complex 2 (PRC2) subunit EZH2 is an essential biomarker of HCC. c-Myc epigenetically silences tumor suppressors by recruiting PRC2 and inducing methylation of histone H3 lysine 27. However, it remains elusive how they are regulated in HCC. We found here that microRNA-26a (miR-26a) suppresses c-Myc, a classical Wnt pathway target gene, by targeting the Wnt pathway coactivator, cyclin-dependent kinase 8 (CDK8); miR-26a also directly targets and inhibits EZH2.
