- Research on the effects of intestinal FXR agonists and antibiotics on the regulation of red kidney bean polysaccharides in the liver metabolism in mice with type 2 diabetes Yunhui Zhang Caili Qi Xingguo Li Mengyuan Geng Honglin Lan Yifang Wei Denglin Luo Zhouya Bai Jinying Guo Sihai Han eFood AbstractOur previous study revealed that red kidney bean polysaccharides (RKB) exhibit a pronounced hypoglycemic effect on type 2 diabetic rats, while simultaneously exerting a significant ameliorative impact on hepatic damage in these animals. However, the precise mechanism underlying the effects of RKB on diabetes and liver metabolism remains unproven. In this study, we utilized a mouse model of type 2 diabetes induced by a high‐fat diet combined with streptozotocin to investigate the impact of RKB. We administered a combined intervention involving antibiotics, fexaramine, and RKB to elucidate the mechanism underlying RKB's effects. Our findings demonstrated that RKB significantly ameliorated liver function indices and histopathological injuries. Nevertheless, when antibiotics and fexaramine were introduced as interventions, they hindered the beneficial effects of RKB on liver function in type 2 diabetic mice. Furthermore, our nontargeted metabolomics analysis revealed that antibiotics and fexaramine exerted their inhibitory actions on RKB efficacy through modulation of distinct metabolites involved in glycerophospholipid and purine metabolic pathways. 10.1002/efd2.159 http://creativecommons.org/licenses/by/4.0/
