Noncytopathic Sindbis virus RNA vectors for heterologous gene expression.
Infection of vertebrate cells with alphaviruses normally leads to prodigious expression of virus-encoded genes and a dramatic inhibition of host protein synthesis. Recombinant Sindbis viruses and replicons have been useful as vectors for high level foreign gene expression, but the cytopathic effects of viral replication have limited their use to transient studies. We recently selected Sindbis r...
متن کاملIntegrating Vectors for Heterologous Gene Expression
A novel shuttle integration cosmid vector (pTOYAMAcos), based on pKU402, and shuttle integration vectors (pTYM18 and pTYM19) were constructed for the cloning of actinomycete DNA and its heterologous expression. These vectors contain oriT of an IncP transmissible plasmid in order to transfer genes by conjugation from Escherichia coli to actinomycetes, and they also contain int derived from actin...
متن کاملStable high-level expression of heterologous genes in vitro and in vivo by noncytopathic DNA-based Kunjin virus replicon vectors.
Primary features of the flavivirus Kunjin (KUN) subgenomic replicons include continuous noncytopathic replication in host cell cytoplasm and the ability to be encapsidated into secreted virus-like particles (VLPs). Previously we reported preparation of RNA-based KUN replicon vectors and expression of heterologous genes (HG) in cell culture after RNA transfection or after infection with recombin...
متن کاملSindbis virus expression vectors: packaging of RNA replicons by using defective helper RNAs.
Since the recovery of infectious RNA transcripts from full-length cDNA clones, alphavirus genome RNAs have been engineered to allow expression of heterologous RNAs and proteins. The highest levels of expression of heterologous products are achieved when the viral structural genes are replaced by the heterologous coding sequences. Such recombinant RNAs are self-replicating (replicons) and can be...
متن کاملA Sindbis virus mRNA polynucleotide vector achieves prolonged and high level heterologous gene expression in vivo.
The direct intramuscular delivery of naked plasmid DNA has been demonstrated to allow expression of encoded heterologous genes in the target myocytes. The method has been employed to elicit immunization based upon delivery of antigen encoding plasmid DNA. For application in the context of achieving anti-tumor immunization against antigenic transforming oncoproteins, delivery of plasmid DNAs enc...
