According to the Kaplan–Meier survival curves, HCC cases with higher RAB42 expression showed poor overall survival (OS) [hazard ratio (HR) = 2.14, p = 3.1e−05], disease specific survival (DSS) [hazard ratio (HR) = 2.51, p = 1e−04] and a worse progress free survival (PFS) [hazard ratio (HR) = 1.35, p = 0.045] (Figures 3A–C). Here, RAB42 is linked to hepatocellular carcinoma.
