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

We used a novel labeling technique in the naturally synchronous organism Physarum polycephalum to examine the fate of core histones in G2 phase. We find rapid exchange of H2A/H2B dimers with free pools that is greatly diminished by treatment of the cells with alpha-amanitin. This exchange is enhanced in pol II-coding sequences compared with extragenic regions or inactive loci. In contrast, H3/H4 tetramers exhibit far lower levels of exchange in the pol II-transcribed genes tested, suggesting that tetramer exchange occurs via a distinct mechanism. However, we find that transcribed regions of the ribosomal RNA gene loci exhibit rapid exchange of H3/H4 tetramers. Thus, our data show that the majority of the pol II transcription-dependent histone exchange is due to elongation in vivo rather than promoter remodeling or other pol II-dependent alterations in promoter structure and, in contrast to pol I, pol II transcription through nucleosomes in vivo causes facile exchange of both H2A/H2B dimers while allowing conservation of epigenetic "marks" and other post-translational modifications on H3 and H4.
