One of the most prevalent malignant tumors and the main reason for cancer-related deaths worldwide is hepatocellular carcinoma (HCC). More and more findings support the abnormal expression of C2H2-ZF protein in the onset and progression of HCC. The C2H2-ZF proteins are involved in various biological functions in HCC, such as EMT, stemness maintenance, metabolic reprogramming, cell proliferation and growth, apoptosis and genomic integrity. The study of anti-tumor drug resistance also highlights the pivotal role of C2H2-ZF protein at the intersection of biological functions (EMT, stemness maintenance, autophagy)and chemoresistance in HCC. The involvement of C2H2-ZF protein found recently in regulating different molecules, signal pathways and pathophysiological activities indicates that the C2H2-ZF protein is a possible therapeutic target for the treatment in HCC and can be applied as a diagnostic or prognostic biomarker.
