ABSTRACT
Our aim was to test the therapeutic effects of adenovirus-mediated gene therapy in an animal brain tumor model which was obtained by stereotactic injection of 9L gliosarcoma cells into the caudate nucleus of rat brains. Seven days after the implantation of tumor cells, adenovirus vectors bearing the Escherichia coli beta-galactosidase gene (ADVbgal) or the herpes simplex virus thymidine kinase gene (ADVtk) were stereotactically injected into the tumor. Injection of the ADVbgal resulted in the expression of the marker gene in 11 animals. Transfer of the ADVtk was followed, 3 days later, by intraperitoneal injection of ganciclovir (GCV) for 10 days. A control group was treated with saline instead of GCV. We observed a significant regression of the tumors in the rats treated with ADVtk and GCV as compared with control animals. In four cases the tumor completely disappeared after treatment. These results demonstrate the potential efficacy of adenovirus-mediated transfer of the HSVtk gene following by GCV administration for the treatment of glioblastomas.
