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

Following erasure in the blastocyst, the entire genome undergoes de novo methylation at the time of implantation, with CpG islands being protected from this process. This bimodal pattern is then preserved throughout development and the lifetime of the organism. Using mouse embryonic stem cells as a model system, we demonstrate that the binding of an RNA polymerase complex on DNA before de novo methylation is predictive of it being protected from this modification, and tethering experiments demonstrate that the presence of this complex is, in fact, sufficient to prevent methylation at these sites. This protection is most likely mediated by the recruitment of enzyme complexes that methylate histone H3K4 over a local region and, in this way, prevent access to the de novo methylation complex. The topological pattern of H3K4me3 that is formed while the DNA is as yet unmethylated provides a strikingly accurate template for modeling the genome-wide basal methylation pattern of the organism. These results have far-reaching consequences for understanding the relationship between RNA transcription and DNA methylation.
