Optimization of radiation controlled gene expression by adenoviral vectors in vitro.
Article in Cancer gene therapy, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
The radiation-inducible EGR-1-promoter has been used in different gene therapy approaches in order to enhance and locally restrict therapeutic efficacy. The aim of this study was to reduce nonspecific gene expression in the absence of irradiation (IR) in an adenoviral vector. Rat rhabdomyosarcoma R1H tumor cells were infected with adenoviral vectors expressing either EGFP or HSV-TK under control of the murine EGR-1 promoter/enhancer. Cells were irradiated at 0-6 Gy. Gene expression was determined by FACS-analysis (EGFP), or crystal violet staining (HSV-TK). The bovine growth hormone polyadenylation signal (BGH pA) was used as insulating sequence and was introduced upstream or upstream and downstream of the expression cassette. Infected R1H cells displayed IR dose-dependent EGFP expression. Cells treated with IR, AdEGR.TK and ganciclovir displayed a survival of 17.3% (6 Gy). However, significant gene expression was observed in the absence of IR with EGR.TK and EGR.EGFP constructs. Introduction of BGHpA upstream or upstream and downstream of expression cassette resulted in decreased nonspecific cytotoxicity by a factor of 1.6-2.3 with minor influence on the induced level of cytotoxicity. Introduction of insulating sequences in adenoviral vectors might allow tighter temporospatial control of gene expression by the radiation-inducible EGR-1 promoter.
