The non-coding RNA (ncRNA)-mediated high expression of polycomb group factor 1 (PCGF1) is a prognostic biomarker and is correlated with tumor immunity infiltration in liver hepatocellular carcinoma.

Background: Liver hepatocellular carcinoma (LIHC) has a poor prognosis worldwide. 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.
