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

Prokaryotes and eukaryotes use diverse strategies to cope with invading mobile genetic elements, including programmed DNA elimination (PDE). In the ciliate Paramecium, elimination of transposable elements and their relics requires the PiggyMac (Pgm) endonuclease and its five PgmL partners, yet how this machinery is targeted to cleavage sites remains unclear. Here, we identified condensin I subunits in the proximity proteomes of Pgm and PgmL4. We show that they belong to a condensin complex that is essential for PDE and localizes to developing somatic nuclei. Depleting the development-specific subunits of this complex blocks DNA elimination, phenocopying a Pgm depletion. Developmental condensin is required for the correct nuclear localization of Pgm and some of the PgmLs. Moreover, Pgm and these PgmLs coimmunoprecipitate with condensin I. Our findings uncover functional and physical interactions between a eukaryotic DNA cleavage machinery and a specialized condensin complex that is critical for PDE in a nondividing nucleus.
