DPO production by gut commensals suggests a broader role in bacterial communication and host-microbiome interactions.
Article in NPJ biofilms and microbiomes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The quorum-sensing molecule 3,5-dimethylpyrazine-2-ol (DPO), known for regulating biofilm formation in Vibrio cholerae, has unknown distribution among commensal bacteria. We screened 37 bacterial strains using a validated biosensor and found widespread production. Inoculating mice with high producers elevated gut DPO levels, highlighting DPO's potential influence on gut microbiota. These findings expand DPO's ecological relevance and underscore quorum sensing as a potentially critical influence on microbiome function and host-microbe interactions.
