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

The cytosine analogue 5-aza-2'-deoxycytidine (decitabine; DAC) covalently inhibits DNA methyltransferase 1 (DNMT1), the maintenance DNA methyltransferase, and induces SUMOylation of DNA-trapped DNMT1, promoting proteasomal degradation. However, the regulation of DNMT1 SUMOylation and its biological impact remain unclear. Here, using interphase Xenopus egg extracts that reconstitute maintenance DNA methylation in vitro, we identify death domain-associated protein (DAXX) as a regulator of SUMOylation on chromatin-retained, inactive DNMT1. First, adding 5-aza-dCTP, the triphosphate form of decitabine, induced DNMT1 accumulation on chromatin and robust SUMO2/3 conjugation. Chromatin mass spectrometry (CHROMASS) revealed DAXX enrichment on 5-aza-dCTP-treated chromatin in a SUMO-dependent manner, and DAXX depletion suppressed 5-aza-dCTP-induced DNMT1 SUMOylation. Furthermore, GSK-3484862, a non-covalent DNMT1 inhibitor, drove DNMT1 accumulation on chromatin and triggered DAXX-dependent DNMT1 SUMOylation. We also demonstrated that DAXX loss increased decitabine sensitivity in the myeloid leukaemia (AML) cell line THP-1. Together, these findings show that DAXX promotes SUMOylation of DNMT1 trapped on DNA under both covalent and non-covalent trapping conditions.
