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

In eukaryotes, chromosomal processes are usually modulated through chromatin-modifying complexes that are dynamically targeted to specific regions of chromatin. In this study, we show that the chromatin-remodeling complex SWR1 (SWR1-C) uses a distinct strategy to regulate heterochromatin spreading. Swr1 binds in a stable manner near heterochromatin to prepare specific chromosomal regions for H2A.Z deposition, which can be triggered by NuA4-mediated acetylation of histone H4. We also demonstrate through experiments with Swc4, a module shared by NuA4 and SWR1-C, that the coupled actions of NuA4 and SWR1-C lead to the efficient incorporation of H2A.Z into chromatin and thereby synergize heterochromatin boundary activity. Our results support a model where SWR1-C resides at the heterochromatin boundary to maintain and amplify antisilencing activity of histone H4 acetylation through incorporating H2A.Z into chromatin.
