Competence of an artificial bent DNA as a transcriptional activator in mouse ES cells.
Article in Molecular biology reports, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Curved DNA structures with a left-handed superhelical conformation can activate eukaryotic transcription. However, their potency in transgene activation in embryonic stem (ES) cells has not been examined. T20 is an artificial curved DNA of 180 bp that serves as a transcriptional activator. We investigated the effect of T20 on transcription in mouse ES cell lines or hepatocytes differentiated from them. We established 10 sets of cell lines each harboring a single copy of the reporter construct. Each set comprised a T20-harboring cell line and a T20-less control cell line. Analyses showed that in ES cells and in hepatocytes originating from these cells, T20 both activated and repressed transcription in a manner that was dependent on the locus of reporter. The present and previous studies strongly suggest that in cells that have a strict gene regulation system, transcriptional activation by T20 occurs only in a transcriptionally active locus in the genome.
