The Kaplan-Meier curves showed that the high expression of DBF4 and SLC16A3 genes was significantly associated with low OS in patients with HCC (Figure 3A-3B), and high expression of ARG2 may indicate a poor prognosis in patients with HCC, but this was not statistically significant (Figure 3C). This evidence concerns the gene SLC16A3 and hepatocellular carcinoma.
