Similar to the findings from the RT-PCR cohort, patients with the high expression KIF4A in TCGA (N = 371) and GSE77314 (N = 50) had shorter survival time than patients with low expression KIF4A, and log-rank P to be 0.00038 and 0.024 (Fig. 2b,c), respectively, confirming the prognostic utility of KIF4A in HCC. The gene discussed is KIF4A; the disease is hepatocellular carcinoma.
