Both sets include Glucose transporter 2-encoding SLC2A2, highly expressed in hepatocytes and favorable prognostic marker in HCC (Uhlén et al, 2015; Uhlen et al, 2017), confirming intratumorally the association between HBV RNA levels and cell differentiation as we previously described at inter-tumor level (Fig 2). Here, SLC2A2 is linked to hepatocellular carcinoma.
