RGS14 and hepatocellular carcinoma: To investigate the biological function of RGS14 in HCC cells, based on RGS14 expression in HCC cell lines (Fig. 3A), we used lentiviral technology to establish stable models of RGS14 overexpression in the Huh7 cell line and RGS14 knockdown in the MHCC97H and SNU387 cell lines (Fig. 3B-D).
