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-binding activators and repressors recruit histone acetylases and deacetylases to promoters, thereby generating localized domains of modified histones that influence transcriptional activity. At the end of a transcriptional response, alterations in histone acetylation status are reversed, but the dynamics of this process are poorly understood. Here, we recruit histone deacetylases and acetylases to a well-defined yeast promoter in a regulated manner. Following dissociation of the recruiting protein from the promoter, targeted deacetylation and acetylation are reversed with rapid, yet distinct, kinetics. Reversal of targeted deacetylation occurs within 5-8 min, whereas reversal of targeted acetylation is more rapid, taking 1.5 min. These findings imply that untargeted, globally acting enzymes generate a highly dynamic equilibrium of histone acetylation and deacetylation reactions across chromatin. Targeted acetylases and deacetylases can locally perturb this equilibrium, yet once they are removed, the global activities mediate a rapid return to the steady-state level of histone acetylation. Our results also indicate that TBP occupancy depends on the presence of the activator, not histone acetylation status.
