Abstract

DNA replication stress is a central molecular event in tumorigenesis and cancer progression. As an essential component of the eukaryotic replisome, the GINS complex, composed of GINS1/PSF1, GINS2/PSF2, GINS3/PSF3, and GINS4/SLD5, cooperates with CDC45 and MCM2-7 to form the Cdc45-MCM-GINS helicase, which drives replication initiation and fork elongation. Aberrant expression of GINS subunits has been linked to cell-cycle activation, genomic instability, epithelial-mesenchymal transition, cancer stemness, immune microenvironment remodeling, and therapeutic resistance. Hepatocellular carcinoma (HCC) remains a major global health burden, with approximately 685000 new cases and 597000 deaths worldwide in 2022, and resistance to immune checkpoint inhibitor-based combinations, dual immunotherapy, and multitarget tyrosine kinase inhibitors continues to limit durable clinical benefit. This minireview summarizes the biological roles of the GINS complex and DNA replication stress in tumor progression, stemness, and therapeutic resistance, with a focus on their translational relevance in HCC. Current HCC evidence mainly implicates GINS1, GINS2, and GINS4, including the emerging GINS4/POLE2/ferroptosis axis, whereas GINS3 remains insufficiently validated. Therefore, the GINS-CMG axis should be regarded as a candidate biomarker and hypothesis-generating therapeutic concept rather than an established causal driver in HCC.

Keywords: GINS complex; DNA replication stress; CMG helicase; Cancer stemness; Therapeutic resistance; Hepatocellular carcinoma

Core Tip: This review highlights the GINS complex, a core component of the CMG helicase, as a candidate molecular link between DNA replication stress adaptation, cancer stemness, epithelial-mesenchymal transition, and therapeutic resistance in hepatocellular carcinoma (HCC). Current evidence is strongest for GINS1, GINS2, and GINS4, whereas HCC-specific functional validation of GINS3 remains limited. The GINS-CMG axis should therefore be viewed as a hypothesis-generating biomarker and translational concept rather than an established therapeutic target.
