1 · What the graph read from it

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.

2 · The registry

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

DNA topoisomerases regulate the topological state of the DNA double helix and are key enzymes in the processes of DNA replication, transcription and genome stability. Using the fission yeast model Schizosaccharomyces pombe, we investigate genome wide how DNA topoisomerases I and II affect chromatin dynamics and gene expression in vivo. We show that topoisomerase I activity is directly required for efficient nucleosome disassembly at gene promoter regions. Lack of topoisomerase activity results in increased nucleosome occupancy, perturbed histone modifications and reduced transcription from these promoters. Strong correlative evidence suggests that topoisomerase I cooperates with the ATP-dependent chromatin remodeller Hrp1 in nucleosome disassembly. Our study links topoisomerase activity to the maintenance of open chromatin and regulating transcription in vivo.
