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 unstimulated mammalian cells and in Saccharomyces cerevisiae, the mouse mammary tumor virus (MMTV) promoter is silent and organized into positioned nucleosomes, one of which encompasses the binding sites for glucocorticoid receptor (GR) and nuclear factor I (NFI). Glucocorticoid induction in vivo involves a functional synergism between GR and NFI and simultaneous occupancy of the promoter sites for both proteins that cannot be reproduced on naked DNA. The role of chromatin in the process of induction was investigated by manipulating the nucleosome density in yeast strains carrying a regulated histone H4 gene. Following depletion of nucleosomes, independent transactivation by NFI or by GR, as well as binding of the individual proteins to the MMTV promoter, were enhanced, in agreement with a repressive function of nucleosomes. In contrast, NFI-dependent hormone induction of the promoter and the simultaneous binding of receptor and NFI were compromised by nucleosome depletion. This effect could be partly mediated by a cryptic binding site for the receptor that is functional only in the nucleosomal context. Thus, positioned nucleosomes do not only account for constitutive repression of the MMTV promoter, but also participate in induction by mediating cooperative binding and functional synergism between GR and NFI.
