HSV-1 amplicon vector-mediated expression of ATM cDNA and correction of the ataxia-telangiectasia cellular phenotype.
Article in Gene therapy, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Ataxia-telangiectasia (A-T) is an autosomal recessive disorder characterized by neurodegeneration, immunodeficiency, cancer predisposition, genome instability, and radiation sensitivity. Previous research has shown that it is possible to correct the hereditary deficiency A-T by DNA transfection in cell culture, but the large size of the ATM cDNA (9 kb) limits the use of many vector types for gene replacement. HSV-1 amplicon vectors provide a means to deliver large genes to cells efficiently and without toxicity. In this study, the FLAG-tagged cDNA for human ATM was inserted into an HSV-1 amplicon under control of the CMV promoter (designated as HGC-ATM). FLAG-ATM expression was confirmed in 293T/17 cells and human A-T fibroblasts (GM9607) after transduction, by immunoprecipitation, Western analysis, and immunocytochemistry. Functional recovery was assessed by two independent assays. First, in vitro kinase assay showed that vector-derived ATM in GM9607 cells could successfully phosphorylate wt p53 using recombinant GST-p53(1-101). Second, in A-T cells infected with the HGC-ATM vector, the extent of accumulation in G2/M phase at 24 h postirradiation was similar to that observed in cells with wild-type endogenous ATM and lower than that observed in A-T cells infected with a control vector. Thus, these vectors provide a tool to test the feasibility of HSV-amplicons as gene therapy vectors for A-T.
