β-Sitosterol β-D-glucoside (BSSG) triggers intestinal inflammation in zebrafish and mouse models prior to neurodegeneration onset.

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
backgroundGlucosylated-sterols can be synthetized endogenously, absorbed through the diet or derive from bacterial infection. Their clinical relevance is currently underestimated, even though their imbalance has been associated with an increased risk of neurodegeneration over the lifespan. We studied the detrimental effects elicited by dietary consumption of the plant-derived β-sitosterol β-D-glucoside (BSSG), known to be associated with the occurrence of ALS-PDC, to elucidate its potential mechanism of action.
methodsZebrafish larvae and adults, as well as mice, were treated with BSSG administered directly in the water or via customized food pellet, respectively. Since the intestine was identified as the primary target tissue, its morphological and functional characteristics were assessed, together with transcriptional profiling and gut microbiota sequencing. Ex vivo analysis of zebrafish gut contractility was applied to evaluate intestinal neuromuscular responses. Mutant and transgenic zebrafish lines were used to explore a potential BSSG mechanism of action.
resultsBSSG induced intestinal inflammation in both zebrafish and mouse models. This previously unknown effect was evidenced by gut dysmotility and inflammatory response. Transcriptomic analyses revealed increased expression of inflammation-related genes in the intestine of both zebrafish and mice, while preliminary gut microbiota analyses suggested the onset of dysbiosis. Transgenic and mutant zebrafish lines, depleted of genes involved in glucocorticoids synthesis and activity, evidenced that BSSG likely interacts with the glucocorticoid receptor, potentially impairing its canonical anti-inflammatory activity.
conclusionsWe identified novel pathways altered by dietary BSSG exposure. This molecule appears to initially induce gut inflammation, leading to changes in intestinal morphology and function, and may contribute to neurodegeneration through disruption of the well-known gut-brain axis.
