Core Tip

Core Tip: In this study, bioinformatics methods were used to explore novel hepatocellular carcinoma (HCC)-specific antigens for mRNA vaccine development and construct an immune subtype of HCC to select the appropriate vaccination population. Tumor-specific antigens were defined as highly expressed, genetically altered, and prognostic genes associated with antigen-presenting cell infiltration. AURKA, CCNB1, CDC25C, CDK1, TRIP13, PES1, MCM3, PPM1G, NEK2, KIF2C, PTTG1, KPNA2, and PRC1 were recognized candidate HCC antigens for mRNA vaccine development. The IS1 and IS3 immune subtypes of HCC were suitable populations for mRNA vaccination. RBP4, KNG1, METTL7A, F12, and ABAT were potential biomarkers for mRNA vaccines.
