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

Base excision repair, initiated by DNA glycosylases, preserves genomic integrity by removing damaged bases. DNA glycosylases Ogg1 and Mutyh were shown to alter the hippocampal transcriptome independently of DNA damage repair. However, the role of DNA glycosylases as transcriptional regulators and their involvement in cognition remain unclear. Here, we combine transcriptomic and epigenomic analyses of the hippocampus in mice deficient in DNA glycosylases. We report that the combined deficiency of Ogg1 and Mutyh impairs spatial long-term memory. Mechanistically, Ogg1 and Mutyh modulate DNA methylation of polycomb repressive complex 2 (PRC2) target genes. PRC2 occupancy and associated histone post-translational modifications depend on Ogg1 and Mutyh in neurons and glia. These epigenetic changes correlate with cell-type specific differences in gene expression of PRC2 targets. Finally, human genetic data link DNA glycosylase-regulated genes to cognitive function, highlighting a novel role for Ogg1 and Mutyh in modulating the epigenome to control transcriptional responses relevant for brain-related diseases.
