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

Nucleosomes, octamers of histones wrapped in 147 bp of DNA, are the basic unit of chromatin. In eukaryotic cells, the placement of nucleosomes along the genome is highly organized, and modulation of this ordered arrangement contributes to regulation of gene expression. The SWI/SNF complex utilizes the energy of ATP hydrolysis to mobilize nucleosomes and remodel chromatin structure. Recently, the complex has also been implicated in oncogenesis as genes encoding multiple SWI/SNF subunits have been found mutated at high frequency across a wide spectrum of cancers. Given that epigenetic aberrations are now characterized as a hallmark of human cancer, hypotheses have been put forth that the SWI/SNF complex inhibits tumor formation by regulating key chromatin functions. To understand how the SWI/SNF complex contributes to nucleosome organization in vivo we performed a genome-wide study in mammalian cells. We found that inactivation of SWI/SNF subunits leads to disruptions of specific nucleosome patterning and a loss of nucleosome occupancy at a large number of promoters. These findings define a direct relationship between the SWI/SNF complex, chromatin structure, and transcriptional regulation. In this extra view, we discuss our findings, their relevance to gene regulation, and possible links to the tumor suppression activities of the SWI/SNF complex.
