Modulation of tumor radiation response with G3139, a bcl-2 antisense oligonucleotide.
Article in Investigational new drugs, 2007. 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
Overexpression of anti-apoptotic bcl-2 protein has been found in hematological and solid tumors and has been associated with increased resistance against cytotoxic therapy. While bcl-2 antisense (AS) treatment combined with chemotherapy has been successfully tested in clinical trials, trials evaluating the combination of bcl-2 AS with radiotherapy have not yet been performed. The aim of this study was to investigate in vivo anti-tumor effects of a combined modality treatment scheme consisting of radiation and the bcl-2 targeted AS oligonucleotide (ODN) G3139 (Oblimersen Sodium). Two human colon carcinoma cell lines, SW620, bcl-2 positive and HT-29, bcl-2 negative, were grown as xenografts and compared in their response to combined bcl-2 AS/radiation treatment. G3139 potentiated the radiation response of bcl-2 positive SW620 tumors, but had no significant effect on bcl-2 negative HT-29 tumors assayed by tumor growth delay. The profound enhancement of SW620 tumor growth delay by G3139 did not translate into effects on tumor cure, as no significant effect of G3139 was found on SW620 radiocurability (TCD50 assay). The control ODN G3622 had no effect on SW620 radiation response, indicating an ODN sequence specific effect.
