Most brain tumors consist of transformed glia cells and are highly vascularized by capillary endothelial cells. The aim of the present study therefore was to deliver pro-apoptotic caspase-3 into malignant C6 glioma and immortalized rBCEC4 brain endothelial cells to induce cell death. Both cell lines were transfected with a reporter protein (beta-galactosidase) using lipid-mediated gene transfer (FuGENE6) or using the novel protein delivery reagent BioPORTER. beta-Galactosidase protein was successfully delivered into both cells, the protein expression peaked around day 2 and was transient. Delivery of caspase-3 induced TUNEL-positive cell death of both cell types. As a control, caspase-3 was also delivered to non-neoplastic primary astrocytes and endothelial cells and induced cell death. In conclusion BioPORTER-protein delivery of pro-apoptotic molecules may provide a potent tool to cause death of the cells in brain tumors, however, this method is limited due to its toxicity to non-malignant cells.
