RAD51 and hepatocellular carcinoma: As shown in Figure 5a, Rad51 expression was markedly reduced in the si-Rad51 group relative to the NC group but markedly elevated in the si-Rad51+ inhibitor group compared to the si-Rad51 group; these results suggested the successful transfection of si-Rad51 and the miR-125a inhibitor into SiHa and HCC-0214 cells.
