Cucurbitacin IIa Alleviates Colitis via Promoting the Release of Host-Derived Extracellular Vesicles Encapsulating microRNA-30b-5p.

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
Purpose: Cucurbitacins have demonstrated anti-inflammatory effects and show promise for inflammatory bowel diseases. However, the underlying mechanisms by which cucurbitacins affect colitis remain largely unknown. Methods: In this study, we investigated the impact of cucurbitacin IIa on dextran sulfate sodium (DSS)-induced colitis in rats and the alterations in intestinal extracellular vesicles (EVs). EVs were isolated and characterized, followed by analysis of the small RNAs and proteins encapsulated within them using small RNA sequencing and proteomics, respectively. Results: Our results revealed that cucurbitacin IIa alleviated colitis symptoms in DSS-treated rats, along with changes in the morphology and composition of intestinal EVs. Notably, EVs from cucurbitacin IIa-treated rats also mitigated colitis symptoms in DSS-treated rats. Further analysis showed that cucurbitacin IIa modified the protein profiles and microRNA composition of EVs extracted from the feces of colitis rats. Specifically, microRNA-30b-5p, significantly increased by cucurbitacin IIa, was found to alleviate colitis symptoms in DSS-treated rats. In conclusion, cucurbitacin IIa appears to alleviate colitis by promoting the release of microRNA-30b-5p from host-derived extracellular vesicles. Conclusion: These findings enhance our understanding of cucurbitacin IIa's effects on intestinal health and offer potential new therapeutic targets for inflammatory bowel disease treatment.
