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

A hallmark of vertebrate genes is that actively transcribed genes are hypomethylated in critical regulatory sequences. However, the mechanisms that link gene transcription and DNA hypomethylation are unclear. Using a trichostatin A (TSA)-induced replication-independent demethylation assay with HEK 293 cells, we show that RNA transcription is required for DNA demethylation. Histone acetylation precedes but is not sufficient to trigger DNA demethylation. Following histone acetylation, RNA polymerase II (RNAP II) interacts with the methylated promoter. Inhibition of RNAP II transcription with actinomycin D, alpha-amanitin, or CDK7-specific small interfering RNA inhibits DNA demethylation. H3 trimethyl lysine 4 methylation, a marker of actively transcribed genes, was associated with the cytomegalovirus promoter only after demethylation. TSA-induced demethylation of the endogenous cancer testis gene GAGE follows a similar sequence of events and is dependent on RNA transcription as well. These data suggest that DNA demethylation follows rather than precedes early transcription and point towards a novel function for DNA demethylation as a memory of actively transcribed genes.
