This work investigated the crosstalk between two of the epigenetic mechanisms: DNA methylation and microRNAs, in hepatocellular carcinoma (HCC). MicroRNA let-7a is a member of the arechetypal let-7a miRNA gene family. Owing to its know tumor suppressor activity, aberrant expression of microRNA let-7a was found to deregulate ~200 gene involved in cell proliferation, differentiation and adhesion UR - http://172.23.153.220/th.pdf ER -
