Furthermore, to investigate the potential association between B56γ and HBV‐related hepatocarcinogenesis, we collected 22 pairs of HBV‐related HCC tumours and adjacent peritumor tissues to analyse the levels of HBV proteins, including HBsAg, hepatitis B core antigen (HBcAg), HBx, and B56γ expression. This evidence concerns the gene PPP2R5C and hepatocellular carcinoma.
