Nucleoporins shape germ granule architecture and balance small RNA silencing pathways.
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 7 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
Animals use small RNA pathways, such as PIWI-interacting RNA (piRNA) and small interfering RNA (siRNA), to silence harmful genetic elements. In Caenorhabditis elegans, piRNA pathway components are organized into sub-compartments within germ granules near nuclear pore complexes, but the basis and function of this association have remained unclear. Here, our data suggest that germ granule formation and nuclear pore clustering are interdependent processes. We identify the conserved nucleoporins NPP-14/NUP214 and NPP-24/NUP88, along with the germ granule protein EPS-1, as key factors anchoring germ granules to nuclear pores. Loss of these factors leads to disorganized, fused granules and enhanced piRNA silencing. Artificial tethering of granule sub-compartments mimics this effect. However, this increase in piRNA silencing comes at the expense of RNA interference efficiency and heritability. Our findings reveal the molecular factors mediating germ granule-nuclear pore interaction and highlight how spatial organization of RNA silencing machinery fine-tunes gene regulation.
