The Kaplan–Meier survival curves also demonstrated that the high expression of the 8 genes was significantly correlated with the poor overall survival (OS) of HCC patients: ATP6AP1 (logrank p = 0.026, HR(high)=1.5), EXO1 (logrank p = 0.00034, HR(high)=1.9), FANCI (logrank p = 0.0066, HR(high)=1.6), HSP90AB1 (logrank p = 0.05, HR(high)=1.4), NUP37 (logrank p = 4.31e-05, HR(high)=2.1), PRIM1 (logrank p = 0.00066, HR(high)=1.8), PSMD14 (logrank p = 0.021, HR(high)=1.5), TUBB (logrank p = 0.0019, HR(high)=1.7) (Fig. 3C). Here, ATP6AP1 is linked to hepatocellular carcinoma.
