To elucidate the role of MYH9 in HCC, we detected MYH9 expression in HCC cells and introduced a plasmid or siRNA to MYH9 into HCC cells and showed a more than twofold change in MYH9 levels in HCC cells treated with the MYH9 plasmid or siRNA compared with the corresponding control cells (Fig. 1a). This evidence concerns the gene MYH9 and hepatocellular carcinoma.
