Abstract We have constructed an improved DNA expression vector based on the Sindbis virus. Several DNA-based Sindbis virus vectors were constructed to investigate the efficiency of transgene expression. These vectors, when transfected into mammalian cells, have been used to express heterologous genes. A recombinant genome of Sindbis plasmid DNA, in which the structural genes were replaced by a polylinker cassette to allow for insertion of heterologous genes, was placed under the control of a simian virus (SV 40) promoter with a hepatitis delta virus (HDV) antigenomic ribozyme and a polyadenylation signal. Transfection of mammalian cells with this Sindbis-based plasmid vector, pSin-SV40-HDV-SV40pA, resulted in transient high-level expression of the beta-galactosidase reporter gene. The expression level of beta-galactosidase from pSin-SV40-HDV-SV40pA was more than 16-fold higher than that of pSin-Lux originally reported by Herweijer et al. In vivo expression was also detected after injection of plasmid DNA into mouse quadriceps. In vivo expression was transient and undetectable after day 14. Furthermore, we demonstrate that the transfection of cells with this Sindbis virus vector results in apoptotic death on glioma cells. We have demonstrated a high-level expression of the exogenous beta-galactosidase gene from the pSin-SV40-HDV-SV40pA construct using a Sindbis replication system.
