Background: There is a growing interest in understanding the association between the gut microbiota and inflammatory bowel disease (IBD). Natural compounds, such as Korean Red Ginseng (KRG), show promise for IBD treatment because of their ability to influence gut microbiota. This study explored the effects of KRG on gut microbiota modulation and subsequent intestinal epithelial cell regeneration in an experimental colitis model.
Method: Using a mouse model of colitis induced by 2 % dextran sodium sulfate, the study administered 200 or 400 mg/kg/day of KRG to evaluate its biological effects. Colitis symptoms were assessed through body weight, disease activity index, colon length, and histological analysis. The microbial composition in the fecal was determined using 16S rRNA sequencing. To evaluate regeneration signals in the colon, western blotting and immunohistochemistry assays were conducted.
Result: Administration of KRG effectively mitigated colitis symptoms in mice, as indicated by histological examination showing alleviated epithelial damage and inflammation, along with increased mucus production. Microbiota analysis showed that KRG significantly altered microbial diversity, favoring beneficial taxa and suppressing harmful taxa. Moreover, ameliorated β-catenin/transcription factor-4 protein expression, a key signal associated with epithelial cell regeneration, was observed in the KRG treated groups, accompanied by improved intestinal linings.
Conclusion: These findings suggest that KRG exerts biological effects in colitis by modulating gut microbiota and creating a favorable intestinal environment, thereby reducing regenerative signals. Further research is warranted to elucidate the cellular and molecular mechanisms underlying the interaction of KRG with gut microbiota and pave the way for effective IBD therapies.
