Abstract: | The Drosophila melanogaster deoxynucleoside kinase gene was introduced into HeLa cells with cationic lipids to allow its transient expression, and cytotoxic effects of several nucleoside analogs in the transfected cells were examined. Of the analogs tested, cytotoxicities of 1-β-D-arabinofuranosylcytosine (araC), 5-fluorodeoxyuridine (FUdR), and 1-(2-deoxy-2-methylene-β-D-erythro-pentofuranosyl)cytosine (DMDC) were increased by the deoxynucleoside kinase gene. These results suggest that the combination of the transient expression of the Drosophila deoxynucleoside kinase gene and these nucleoside analogs is a candidate for the suicide gene therapy. |
