EXO1 and hepatocellular carcinoma: K–M survival curve analysis showed that HCC patients with a high-EXO1 expression were associated with significantly lower OS (p < 0.001) (Figure 8A), DSS (p < 0.001) (Figure 8B) and progression-free interval (PFI) (p = 0.001) compared to those with low-EXOI expression levels (Figure 8C).
