A Novel Four-Gene Signature as a Potential Prognostic Biomarker for Hepatocellular Carcinoma

Figure 5

The validation of signatures in our patient cohort. (a) qRT-PCR analysis: mRNA expression levels of four genes in HCC and paired nontumorous liver tissues. (b) ROC analysis of four genes. (c) Kaplan–Meier survival plots of the four-gene signature in TCGA cohort. (d) Kaplan–Meier survival plots of the four-gene signature in our patient cohort.
