Recent advances in diagnostics, staging, and therapy for pancreatic cancer have not resulted in significant improvements in long-term survival, and development of new approaches is particularly urgent. The use of prodrug-activating genes is a possible approach for cancer gene therapy. The aim of this study was to evaluate the efficacy of Escherichia coli purine nucleoside phosphorylase (ePNP) on pancreatic tumors. ePNP activates the prodrug 6-methylpurine deoxyribose (MePdR) into methyl purine (MeP), which is highly toxic to dividing and nondividing cells.
