In this systematic review, we integrated evidence from public databases and experimental studies to identify and evaluate 16 potential pancreatic cancer mRNA vaccine antigens (ADAM9, WNT7A, TMOD3, MET, EFNB2, TPX2, AGPS, OSBPL9, KDM5A, NRAS, SCP-1, GAGE, RAB5A, ANO6, CHMP2B, and PAK2). This evidence concerns the gene PAK2 and pancreatic neoplasm.
