Microbially derived glutathione from Eubacterium rectale alleviates oxidative stress and promotes intestinal epithelial recovery.

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
backgroundCertain microbes inhabiting the gut have been implicated in maintaining gut homeostasis and promoting gut damage repair. Lachnospiraceae members were highly detected in dysbiotic IL-10 KO mice that displayed similar physiological outcomes as control mice. Lachnospiraceae is a highly diverse family of microbes that have been shown to display both commensal and pathogenic characteristics in the colon environment.
resultsWe investigated the impact of genetic variation in five Lachnospiraceae strains on lowering cellular inflammation and reactive oxygen species (ROS) levels. Cell-free spent media (CFSM) from Eubacterium rectale resulted in lowered ROS, and nitric oxide levels in stressed colon cells and colon organoids. CFSM-treated organoids showed reduced ROS accumulation, improved epithelial integrity, and partial recovery of barrier function compared to oxidatively stressed controls. We demonstrated through shotgun metagenomics, metabolomics, host RNA sequencing, and molecular techniques that glutathione (GSH) biosynthesized by E. rectale alleviated host ROS damage. We showed downregulation of cell stress and immune response genes, indicating recovery from ROS stress. Chemical depletion of GSH in CFSM confirmed the role of microbial derived GSH in alleviation of ROS in colon cells.
conclusionsIn this study, we identify E. rectale as a potential probiotic by lowering colon inflammation and ROS damage through production of reduced glutathione. Microbially derived GSH has not been well established in the Lachnospiraceae family which are a large member of the overall gut microbiota. Understanding more about the impacts of microbial functions including GSH on lowering inflammation is needed to develop potential probiotics or therapies for chronic inflammatory conditions.
