Abstract
Enzyme combinations useful for destroying cells, particularly proliferative cells, are disclosed. In particular, a combination of the following enzymes has been found to enhance the toxicity of nucleoside analogues to proliferating cells: an enzyme that phosphorylates the non-toxic nucleoside analogue to generate a monophosphate analogue, an enzyme that phosphorylates the monophosphate analogue to generate a diphosphate analogue and an enzyme that phosphorylates the diphosphate analogue to generate a toxic triphosphate analogue. Vectors enabling the intracellular expression and transfer of the enzyme combinations, as well as their therapeutic use, particularly in anti-cancer gene therapy, are also disclosed.
