In Figure 4, the highest mRNA expression of DDX41 was found in stage 4 (Figure 4G), while the highest mRNA expression of XRCC5, IRF3, TRIM21, STAT6, TBK1, XRCC6, TREX1, and PRKDC was found in stage 3 (Figure 4A–C,E,H–K), which may be attributed to the small sample numbers (only six patients with stage 4 HCC). Here, TREX1 is linked to hepatocellular carcinoma.
