Plasmid DNA Sequences Present in Conventional Herpes Simplex Virus Amplicon Vectors Cause Rapid Transgene Silencing by Forming Inactive Chromatin
14 Mar 2006
Abstract excerpt
The herpes simplex virus (HSV)-based amplicon vector, a bacterial-viral-mammalian cell shuttle system, holds promise as a versatile gene delivery vehicle because of its large transgene capacity. However, amplicon-mediated transgene expression is often transient. We hypothesized that the presence of prokaryotic DNA sequences within the packaged vector genome can trigger transcriptional silencing of the entire...
