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

p53 is a major sensor of cellular stresses, and its activation influences cell fate decisions. We identified SUV39H1, a histone code 'writer' responsible for the histone H3 Lys9 trimethylation (H3K9me3) mark for 'closed' chromatin conformation, as a target of p53 repression. SUV39H1 downregulation was mediated transcriptionally by p21 and post-translationally by MDM2. The H3K9me3 repression mark was found to be associated with promoters of representative p53 target genes and was decreased upon p53 activation. Overexpression of SUV39H1 maintained higher levels of the H3K9me3 mark on these promoters and was associated with decreased p53 promoter occupancy and decreased transcriptional induction in response to p53. Conversely, SUV39H1 pre-silencing decreased H3K9me3 levels on these promoters and enhanced the p53 apoptotic response. These findings uncover a new layer of p53-mediated chromatin regulation through modulation of histone methylation at p53 target promoters.
