Integration of active human beta-galactosidase gene (100 kb) into genome using HSV/AAV amplicon vector.
Article in Gene therapy, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Vectors based on herpes simplex virus type-1 (HSV-1) permit delivery of transgenes of up to 150 kb, while the inverted terminal repeats and Rep of the adeno-associated virus (AAV) can confer site-specific integration into the AAVS1 site, which allows sustained expression of a transgene. In this study, combination of the viral elements in HSV/AAV hybrid vectors has been applied for the infectious transfer of the human lysosomal beta-galactosidase (BGAL) gene of 100 kb. Temporary expression and functional activity of beta-galactosidase (beta-gal) could be detected in human beta-gal-deficient patient and glioblastoma (Gli36) cells upon infection with the basic BGAL amplicon vector. Sustained expression of beta-gal was achieved in Gli36 cells infected with rep-plus, but not rep-minus, HSV/AAV hybrid vectors. None of five clones isolated after rep-minus hybrid vector infection showed elevated beta-gal activity or site-specific integration. In contrast, 80% of the rep-plus clones possessed beta-gal activity at least twofold greater than normal levels for up to 4 months of continuous growth, and 33% of the clones exhibited AAVS1-specific integration of the ITR-flanked transgene. One of the rep-plus clones displayed integration of the ITR cassette only at the AAVS1 site, with no sequences outside the cassette detectable and beta-gal activity fourfold above normal levels. These data demonstrate AAVS1-specific integration of an entire genomic locus and expression of the transgene from the endogenous promoter mediated by an HSV/AAV hybrid vector.
