Analysis of the protein expression levels of genes associated with the HCC-TP-TME risk subtype showed, that XPO1, RCN2, PEX11B, P2RX4, LANCL1, ATP5MF, ALG6, TRIM22, GUCY1A3, CTSC, and ALDH1B1 were significantly elevated in tumor tissues compared with adjacent tumor tissues (Figure 4G). Here, P2RX4 is linked to hepatocellular carcinoma.
