The GG carriers exhibited significantly higher EpCAM gene and protein expression levels compared to the GC + CC carriers in each of the three studied groups (P < 0.05 and P < 0.0001 regarding gene and protein expression, respectively, within the control group; P < 0.0001 for both gene and protein expression within each of the HCV and HCC groups). This evidence concerns the gene EPCAM and hepatocellular carcinoma.
