On the other hand, results from disease-free survival analysis showed that HCC patients with high levels of RelB (HR = 1.5, P = 0.0055) and NF-κB2 (HR = 1.7, P = 0.00061) had poor disease-free survival, whereas RelA, Rel, and NF-κB1 expression had no significant effect on disease-free survival of HCC patients (Figure 3(b)). This evidence concerns the gene REL and hepatocellular carcinoma.
