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

The yeast PHO5 promoter is a model system for the role of chromatin in eukaryotic gene regulation. Four positioned nucleosomes in the repressed state give way to an extended DNase I hypersensitive site upon induction. Recently this hypersensitive site was shown to be devoid of histone DNA contacts. This raises the mechanistic question of how histones are removed from the promoter. A displacement in trans or movement in cis, the latter according to the well established nucleosome sliding mechanism, are the major alternatives. In this study, we embedded the PHO5 promoter into the context of a small plasmid which severely restricts the space for nucleosome sliding along the DNA in cis. Such a construct would either preclude the chromatin transition upon induction altogether, were it to occur in cis, or gross changes in chromatin around the plasmid would be the consequence. We observed neither. Instead, promoter opening on the plasmid was indistinguishable from opening at the native chromosomal locus. This makes a sliding mechanism for the chromatin transition at the PHO5 promoter highly unlikely and points to histone eviction in trans.
