Objective : We investigated the feasibility of a double suicide gene/prodrug therapy, involving direct introduction of the herpes simplex virus Type 1 thymidine kinase(TK) gene and the Escherichia coli cytosine deaminase(CD) gene, via a recombinant adenoviral vector and ganciclovir(GCV) and/or 5-fluorocytosine(5-FC) treatment, in C6 glioma cells. Methods : Efficient gene transfer and transduction of C6 glioma cells via a recombinant adenovirus were evaluated by infecting cells with adenovirus bearing the ${\beta}$-galactosidase gene and then staining cells with 5-bromo-4-chloro-3-indolyl-13-D-galactoside. CD/TK expression in cells infected with adenovirus bearing the CD/TK gene(ad-CD/TK) was examined by immunoblotting analysis. For in vitro cytotoxicity experiments, the cells were infected with ad-CD/TK or ad-${\Delta}E1$(as a control). After addition of a variety of concentrations of GCV and 5-FU, either separately or in combination, cell viability was determined by staining the cells with crystal violet solution 6 days after infection. Result : C6 glioma cells were efficiently transduced with recombinant adenoviral vector at multiplicities of infection of 200 or more. In vitro cytotoxicity of GCV and/or 5-FC, either alone or in combination, was exclusively observed in the cells transduced with ad-CD/TK. Obvious cytotoxicity(>50% inhibition) was observed in the presence of 5-FC at concentrations greater than 30ug/ml or GCV at concentrations greater than 0.3ug/ml at a multiplicity of infection of 100. Additionally, cytotoxicity in the presence of both GCV and 5-FC was greater than that after sinlge-prodrug treatments, indicating additive effects of the prodrug treatments. Conclusion : The administration of a double-suicide gene/prodrug therapy might have great potential in the treatment of brain tumors.
