Kaplan-Meier analyses revealed that overall survival (OS) among HCC patients exhibiting low DCAF15 mRNA expression was poorer than among those exhibiting high DCAF15 mRNA expression, and that low DCAF15 or high ZEB1 mRNA expression was predictive of unfavorable OS in HCC patients (Supplementary Figure 1). This evidence concerns the gene ZEB1 and hepatocellular carcinoma.
