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

Arrest of cell differentiation is one of the leading causes of leukemia and other cancers. Induction of cell differentiation using pharmaceutical agents has been clinically attempted for the treatment of these cancers. Epigenetic regulation may be one of the underlying molecular mechanisms controlling cell proliferation or differentiation. Here, we report on the use of proteomics-based differential protein expression analysis in conjunction with quantification of histone modifications to decipher the interconnections among epigenetic modifications, their modifying enzymes or mediators, and changes in the associated pathways/networks that occur during cell differentiation. During phorbol-12-myristate 13-acetate-induced differentiation of U937 cells, fatty acid synthesis and its metabolic processing, the clathrin-coated pit endocytosis pathway, and the ubiquitin/26 S proteasome degradation pathways were up-regulated. In addition, global histone H3/H4 acetylation and H2B ubiquitination were down-regulated concomitantly with impaired chromatin remodeling machinery, RNA polymerase II complexes, and DNA replication. Differential protein expression analysis established the networks linking histone hypoacetylation to the down-regulated expression/activity of p300 and linking histone H2B ubiquitination to the RNA polymerase II-associated FACT-RTF1-PAF1 complex. Collectively, our approach has provided an unprecedentedly systemic set of insights into the role of epigenetic regulation in leukemia cell differentiation.
