Protective Effect of Pediococcus pentosaceus Li05 on Constipation via TGR5/TPH1/5-HT Activation.
Article in Microbial biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Pediococcus pentosaceus Li05, a strain of lactic acid bacteria isolated from the faeces of healthy volunteers, exhibited potential protective effects against various diseases. This study performed third-generation sequencing and detailed characterisation of its genome. The Li05 chromosome harboured conserved genes associated with acid resistance (atp), bile salt resistance (bsh), oxidative stress resistance (hsl, dltA, and et al.), and adhesion (nrd, gap, and et al.), whereas the plasmid did not contain antibiotic resistance or virulence genes. Following intervention with Li05 in loperamide-induced constipated mice, constipation symptoms improved. Meanwhile, alterations in gut microbiota, increased BSH activity in faeces, and modifications to the faecal bile acid profile were observed. Additionally, expression levels of TGR5 and TPH1 in the colon of the mice increased, leading to elevated 5-HT levels. When the TGR5 gene was knocked out or the TPH1 inhibitor LX1606 was administered to suppress 5-HT synthesis in constipated mice, the beneficial effects of Li05 on gastrointestinal motility and mucus secretion were reversed. Culturing intestinal organoids demonstrated that increased bile acids such as DCA, Iso-LCA, and EALCA could enhance 5-HT levels through the TGR5/TPH1 axis. Therefore, we concluded that Li05 regulated bile acid metabolism, subsequently increasing 5-HT levels through the TGR5/TPH1 axis, thus alleviating constipation.
