TKT and hepatocellular carcinoma: Venn diagram analysis demonstrated elevated expression of 71 common genes in the blood and IT tissues of patients with HCC (Figure 6B), including genes encoding secretory effector proteins (LAIR2, IFNG, and SERPINB1), membrane proteins (TIGIT, TKT, HLA-DRA, RHOB, HLA-DRB1, ADGRG1, HLA-DPA1, SELPLG, and FCGR3A), and other products (Figure 6C).
