For their prognostic effects, through Kaplan-Meier analysis, at protein level, KPNA2 (p < 0.001; Figure 7A) and GRB2 (p < 0.05; Figure 7B) were shown to be unfavorable prognostic factors for HCC OS, consistent with their unfavorable prognostic effects at mRNA level. This evidence concerns the gene KPNA2 and hepatocellular carcinoma.
