Multigenerational proteolytic inactivation of restriction upon subtle genomic hypomethylation in Pseudomonas aeruginosa.
Article in Nature microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
Restriction-modification (R-M) systems protect against phage infection by detecting and degrading invading foreign DNA. However, like many prokaryotic anti-phage defences, R-M systems pose a major risk of autoimmunity, exacerbated by the presence of hundreds to thousands of potential cleavage sites in the bacterial genome. Pseudomonas aeruginosa strains experience the temporary inactivation of restriction endonucleases following growth at high temperatures, but the reason and mechanisms for this phenomenon are unknown. Here we report that P. aeruginosa type I restriction endonuclease is degraded and the methyltransferase is partially degraded, by two Lon-like proteases when replicating at >41 °C. This post-translational regulation prevents self-DNA targeting, which is a risk due to stable genomic hypomethylation, as demonstrated by single-molecule, real-time sequencing and TadA-assisted N
