Abstract:Background: miR-155 is a widely reported carcinogenic miRNA, with up-regulated expression in a variety of human cancers. Methods: Liver cancer stem cells were isolated from Huh7 cells; gene infection, RT-PCR, Western blotting and tumorigenesis test in vitro and in vivo were performed to analyze the signaling pathway. Results: we demonstrate that miR-155 inhibits the expression of MBD5 and METTL3 , reducing the expression of DNMT1. In particular, miR155 inhibits the interaction between MBD5 and DNMT1, thereby i… Show more
