Abstract
A defective adenovirus (Ad) type 5 E1- vector has been combined with the powerful constitutive cytomegalovirus (CMV) major immediate early (IE) promoter to produce a novel eukaryotic expression system. The Ad vector can replicate to high titres in 293 cells and then be used to infect a wide variety of non-permissive cell types. The Escherichia coli lacZ and CMV IE1 genes have been cloned to generate the Ad recombinants RAd35 and RAd31 respectively. In human fibroblasts infected with RAd35 beta-galactosidase (beta-gal) expression could be detected in virtually 100% of target cells, there was no detectable transcription from the Ad genome and extremely high levels of expression could be achieved with beta-gal representing the predominant cytoplasmic cellular protein. Additionally, a number of agents, including the CMV IE1 gene product (in RAd31) and forskolin, significantly enhanced expression from RAd35-infected human fibroblasts. Lower levels of constitutive beta-gal expression were obtained in RAd35-infected HeLa cells but again expression could be enhanced (up to 60 fold) by chemical inducing agents. Expression from the IE promoter in the Ad vector could be repressed by coinfection with CMV.
