title: Cytotoxicity of human beta-interferon produced in human glioma cells transfected with its gene by means of liposomes.
abstract: The cytotoxicity of human beta-interferon (HuIFN-beta) produced in human glioma cells was examined by use of our liposomes entrapping two plasmids, pSV2neo and pSVMTV-IFN-beta. After the cells had been transfected with these genes by means of the liposomes, neomycin-resistant cells were selected. When the selected cells were subjected to a single exposure to dexamethasone, all of the cells were found to produce HuIFN-beta and were eliminated by 8 days. Accordingly, the effect of HuIFN-beta produced in human glioma cells is considered to be cytocidal.
