Cetobacterium somerae ZNN-1 promotes goblet cell differentiation through glutamine-mediated Notch signaling suppression.
Article in Journal of advanced research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionThe gut microbiota acts as a crucial mediator in the interaction between the diet components and the host metabolism. However, the molecular mechanism by which the gut microbiota adapts to dietary components and subsequently regulates host physiological responses remains unclear.
objectivesThis study aimed to investigate the response of gut microbiota to a plant-based protein diet (soybean meal, SM) and the effects of gut microbiota on host intestinal barrier function, along with the underlying mechanisms in a fish model.
methodsHistopathological examination, and transepithelial electrical resistance test were used to evaluate the effects of Cetobacterium somerae on intestinal barrier function. Potential molecular mechanisms were validated by integrating whole-genome sequencing, microbiota composition sequencing, transcriptomics, and metabolomics, and utilizing in vitro cell models and mouse-derived organoid models.
resultsThe results revealed that the SM diet significantly increased the abundance of Cetobacterium somerae in fish. Administration of C.somerae ZNN-1, a dominant strain isolated from the intestine of fish fed with the SM diet, enhanced the intestinal barrier function, particularly increasing the number of goblet cells in the intestine. Whole genome analysis of C. somerae ZNN-1 showed carbohydrate metabolism-associated genes were the most abundant in its metabolic modules. C.somerae ZNN-1 supplementation significantly inhibited the Notch signaling pathway in fish intestine. Metabolomics analysis revealed that administration of C.somerae ZNN-1 increased the glutamine level in fish gut. In vitro experiments demonstrated that glutamine regulated the differentiation of goblet cell by inhibiting the Notch signaling pathway in both human intestinal epithelial cell model and mouse intestinal organoid model.
conclusionC. somerae served as a key bacterium adapted to soybean meal-derived carbohydrates, and it promoted goblet cell differentiation by inhibiting the Notch pathway. This study provides a new perspective for unraveling the interaction mechanisms among diet components, intestinal microbiota and host health.
