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 activity of p53 as a tumor suppressor primarily depends on its ability to transactivate specific target genes in response to genotoxic and other potentially mutagenic stresses. Several histone acetyl transferases (HATs), including p300, CBP, PCAF and GCN5 have been implicated in the activation of p53-dependent transcription of the cyclin-dependent kinase (cdk) inhibitor p21 as well as other target genes. Here we show that PCAF, but not CBP or p300, is a critical regulator of p53-dependent p21 expression in response to multiple p53-activating stresses. PCAF was required for the transcriptional activation of p21 in response to exogenous p53 in p53-null cells, nutlin-3, DNA damaging agents and p14(ARF) expression, suggesting a broad requirement for PCAF in p53 signaling to p21 after stress. Importantly, cells lacking PCAF failed to undergo cell cycle arrest in response to nutlin-3 treatment or p14(ARF) expression, consistent with a physiologically important role for PCAF in this p53 function. Surprisingly, the role for PCAF in induction of p21 was independent of p53 lysine 320 acetylation, a previously suggested target of PCAF-mediated acetylation. Though p21 promoter occupancy by p53 was not altered by PCAF knockdown, activation of p21 transcription required an intact PCAF HAT domain, and induction of chromatin marks acetyl-H3K9 and acetyl-H3K14 at the p21 promoter by p53 was dependent upon physiologic levels of PCAF. Together, our experiments indicate that PCAF is required for stress-responsive histone 3 acetylation at the p21 promoter, p53-directed transcription of p21 and the resultant growth arrest.
