Cepharanthine ameliorates dextran sulphate sodium-induced colitis through modulating gut microbiota.

ABSTRACT: Cepharanthine (CEP) is an active alkaloid isolated from Stephania Cepharantha Hayata. It is reported that the anti-inflammatory properties of CEP could be employed to treat a variety of diseases. In this study, we first found that CEP ameliorates ulcerative colitis (UC) induced by DSS. The effect of CEP on gut microbiota was further evaluated by 16S rRNA gene sequencing, antibiotic pretreatment and faecal microbiota transplantation (FMT). Results showed that the abundances of gut microbiota, such as Romboutsia, Turicibacter and Escherichia-Shigella (especially Romboutsia), were significantly reduced after CEP treatment. Additionally, we explored the mechanisms of CEP by a strategy integrating transcriptomics with network pharmacology. The transcriptome data confirmed that CEP functioned through cytokine and cytokine receptor pathways. The expression levels of 10 pro-inflammatory hub genes (such as CXCL1, CXCL9, CCL7) were positively correlated with the abundance of Romboutsia. Our data identified Romboutsia as a potential pathobiont in UC. Collectively, we confirmed that CEP relieved colon inflammation by modulating gut microbiota and pro-inflammatory cytokine expression. CEP can be adopted to design novel effective therapeutic strategies for UC.

Project description:BackgroundInflammatory bowel disease (IBD) encompasses chronic inflammation of the colon and rectum, posing significant health challenges. Previous studies have shown potential therapeutic effects of natural compounds on IBD. Chrysin, a naturally occurring flavonoid, has been suggested to modulate inflammatory pathways and gut microbiota, but its comprehensive impact on ulcerative colitis remains inadequately explored.MethodsThis study employed a dextran sulfate sodium (DSS)-induced ulcerative colitis model in mice to investigate the effects of Chrysin. Using network pharmacology, we identified key signaling pathways potentially influenced by Chrysin. Experimental approaches included measuring disease activity index scores, serum levels of TNF-α, and assessing colon damage histologically. Transcriptomic and microbiome analyses were conducted to examine changes in gene expression and gut bacterial populations, respectively. Additionally, metabolomic profiling was used to identify alterations in colon metabolites.ResultsChrysin treatment significantly mitigated weight loss and reduced disease activity index scores in DSS-induced mice. There was a notable decrease in serum TNF-α levels and less histological damage in the colon. Transcriptomic analysis revealed significant alterations in gene expression within the NF-κB and IL-17 signaling pathways. Microbiome analysis showed significant shifts in the populations of Bacteroidetes and Firmicutes. Metabolomics analysis identified changes in 298 colon metabolites, implicating several essential metabolic pathways.ConclusionsThe findings suggest that Chrysin exerts a dual-action therapeutic effect on ulcerative colitis by reducing inflammation and modulating the gut microbiota. These multifaceted impacts highlight Chrysin's potential utility as a novel therapeutic agent in the clinical management of IBD, offering valuable insights into its mechanisms of action and paving the way for future clinical trials.
