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

During tissue differentiation, gene expression patterns are committed to the epigenetic cellular memory machinery, including Polycomb and Trithorax groups (PcG and TrxG), which label chromatin with repressive or active histone marks. Histone marks recruit effector proteins that then execute local chromatin repression or activation. The effectors of TrxG have remained largely unknown. Here we report that the Poly (ADP-ribose) Polymerase 1 (PARP1) and Poly (ADP-ribose) Glycohydrolase (PARG) function as critical effectors of TrxG and PcG, respectively. We found that PARP1 binds TrxG-generated histone marks with high affinity in vitro, completely colocalizing with them genome-wide, and controls the expression of loci modified by TrxG. Conversely, PARG preferentially associates with PcG-occupied loci. We propose a model in which TrxG complexes prime chromatin for PARP1 recruitment, leading to poly (ADP-ribose) generation to maintain an open chromatin state essential for transcription.
