Chromosomal domain formation by archaeal SMC, a roadblock protein, and DNA structure.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
In eukaryotes, structural maintenance of chromosomes (SMC) complexes form topologically associating domains (TADs) by extruding DNA loops and being stalled by roadblock proteins. It remains unclear whether a similar mechanism of domain formation exists in prokaryotes. Using high-resolution chromosome conformation capture sequencing, we show that an archaeal homolog of the bacterial Smc-ScpAB complex organizes the genome of Thermococcus kodakarensis into TAD-like domains. We find that TrmBL2, a nucleoid-associated protein that forms a stiff nucleoprotein filament, stalls the T. kodakarensis SMC complex and establishes a boundary at the site-specific recombination site dif. TrmBL2 stalls the SMC complex at tens of additional non-boundary loci with lower efficiency. Intriguingly, the stalling efficiency is correlated with structural properties of underlying DNA sequences. Our study illuminates a eukaryotic-like mechanism of domain formation in archaea and a role of intrinsic DNA structure in large-scale genome organization.
