ABSTRACT
As one of the key bioactive food ingredients in pomegranate, punicalagin (PA) possesses wide-ranging functional activities. However, the knowledge on PA-modulated microbial interactions and their physiological relevance in the gastrointestinal tract is limited. In this study, the modulating effects of PA on host-microbiota interactions were examined using multi-omics approaches in two colitis models. In a chemical colitis model, PA ingestion dampened intestinal inflammation and repressed gut microbial diversity. PA significantly reversed multiple lipids and γ-glutamyl amino acids from elevated levels in colitis mice to the baseline. Anti-inflammatory and microbiota-modulating effects of PA were further validated in an infectious colitis model induced by Citrobacter rodentium, in which PA also restored the microbial dysbiosis index to the baseline and promoted microbial interactions. Multiple microbial signatures with high predictive accuracy for key colitis pathophysiological parameters were identified, which can be developed as biomarkers for monitoring the efficacy of PA-containing functional foods in promoting gut health. Our findings should facilitate the exploitation of dual applications of PA as a bioactive food ingredient and a therapeutic agent.
