Real-time PCR (Figure 2A,B) and Western blotting (Figure 2C,D, and Supplementary Figure S1) revealed that WNT7B levels were higher in pCH9/3091 and HBV1.3 transfected cells than in control cells, implying that HBV infection increases WNT7B expression in HCC cells. Here, WNT7B is linked to hepatocellular carcinoma.
