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 novel scintillation proximity high throughput assay (SPA) to identify inhibitors of DNA methyltransferases was developed and used to screen over 180,000 compounds. The majority of the validated hits shared a quinone core and several were found to generate the reactive oxygen species, H2O2. Inhibition of the production of H2O2 by the addition of catalase blocked the ability of this group of compounds to inhibit DNA methyltransferase (DNMT) activity. However, a related compound, SW155246, was identified that existed in an already reduced form of the quinone. This compound did not generate H2O2, and catalase did not block its ability to inhibit DNA methyltransferase. SW155246 showed a 30-fold preference for inhibition of human DNMT1 versus human or murine DNMT3A or -3B, inhibited global methylation in HeLa cells, and reactivated expression of the tumor suppressor gene RASSF1A in A549 cells. To our knowledge, this work represents the first description of selective chemical inhibitors of the DNMT1 enzyme.
