Intriguingly, it showed that HCC patients with high‐risk scores generally had higher protein levels of RRM1, UCK2 and G6PD than those with low scores (Figure 4F), and HCC patients in the low‐risk group had a better prognosis than those in the high‐risk group (Figure 4I, L). The gene discussed is G6PD; the disease is hepatocellular carcinoma.
