As shown in Figure 1A, our results, which used β-actin as the internal control for normalization, revealed that HCC tissues had significantly higher NDRG3 expression (4.37 ± 0.527) than that of their neighboring non-tumor tissues (2.81 ± 0.292) (mean ± SEM values, P<0.05). This evidence concerns the gene NDRG3 and hepatocellular carcinoma.
