Polycomb group factor 1 (PCGF1) was recently reported to play a tumor suppressive role in cancers. However, the molecular mechanism and competitive endogenous ribonucleic acid (ceRNA) regulatory networks of PCGF1 in LIHC are still unclear.<h4>Methods</h4>We constructed a PCGF1 ceRNA regulatory network in LIHC and identified potential prognostic markers, especially for tumor immunity. We identified the gene expression profiles and conducted correlation and survival analyses of PCGF1 and the related RNAs. We also explored the clinicopathological features and diagnostic and prognostic values of PCGF1 and constructed a nomogram to predict 1-, 3-, and 5-year survival.
