Lactobacillus Salivarius-Derived Indole-3-Acetic Acid Promotes AHR-PARP1 Axis-Mediated DNA Repair to Mitigate Intestinal Aging.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2026. 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
Increasing evidence suggests that the aryl hydrocarbon receptor (AHR) and poly (ADP-ribose) polymerase 1 (PARP1) are closely linked to aging and aging-related disorders. However, the underlying mechanisms of AHR-PARP1 axis-mediated DNA repair in countering aging remain largely unknown. In this study, it is found that both aged humans and mice exhibit marked intestinal aging, characterized by gut dysbiosis and dysfunction and DNA damage, compared to their young counterparts. Intriguingly, it is discovered that intestinal AHR activation by indole-3-acetic acid (IAA), which is derived from Lactobacillus salivarius rather than host cells, effectively mitigates intestinal aging by regulating DNA-damage responses. Mechanistically, activated AHR by IAA interacts with PARP1, potentiating PARP1 activity and the polymerization of poly (ADP-ribose) (PARylation) by binding to its promoter. This interaction enhances intestinal barrier function and suppresses inflammation and cell senescence. Finally, the interplay between AHR and PARP1 is confirmed by in vivo and in vitro experiments, including intestine-specific Ahr knockout mice, Ahr and Parp1 knockdown, and Parp1 overexpression in enterocytes. These findings provide a potential intervention strategy targeting AHR-PARP1 axis to mitigate age-related intestinal dysfunction.
