Erchen Decoction Alleviates High-Fat Diet + AOM/DSS-Induced CRC by Ameliorating Cholesterol-Bile Acid Metabolism Disorder through Regulating FXR and the Gut Microbiota
Summary
Researchers found that Erchen Decoction, a traditional Chinese medicine formula, alleviates colorectal cancer progression in a high-fat diet mouse model by correcting cholesterol-bile acid metabolism disorders through modulation of FXR signaling and gut microbiota composition.
Abstract The incidence of colorectal cancer (CRC) is closely related to dietary factors. Dietary factors greatly affect the structure and function of intestinal microorganisms. In the process of cholesterol bile acid metabolism, the gut microbes participate in the conversion of primary bile acid to secondary bile acid and play an important role in the occurrence and development of CRC. Erchen decoction (ECD) has been widely used in basic research and clinical treatment as a traditional Chinese medical prescription, particularly for patients who are overweight and exhibit dyslipidemia. It is widely used in clinical practice in patients with phlegm syndrome in early colorectal cancer. However, the effects of this treatment on microorganisms and the underlying metabolic mechanisms are still unclear. In this study, a model of high-fat diet and azoxymethane combined with dextran sodium sulfate (AOM/DSS) was established, and ECD intervention was administered to investigate the incidence rate of CRC under different dietary conditions, as well as the effect of ECD intervention on CRC mice fed a high-fat diet. The results showed that the incidence rate of colorectal neoplasms increased under conditions of a high-fat diet, and ECD could reduce the incidence of CRC by regulating abnormal lipid metabolism and improving the structure and function of the intestinal flora.

Researchers found that a traditional Chinese herbal medicine formula called Jianwei Xiaoshi oral liquid improved functional digestive problems in young rats fed a high-calorie diet by regulating eight key proteins involved in pancreatic digestion and restoring healthy gut bacteria balance. The findings suggest potential therapeutic benefits of this herbal remedy for diet-induced digestive disorders in children.
Ameliorative effects of mulberry fruit anthocyanin extract on gut microbiota and liver metabolites in high-fat and high-cholesterol diet-fed ApoE−/− mice
Researchers investigated mulberry anthocyanin extract in high-fat, high-cholesterol diet-fed mice and found it reduced LDL cholesterol and inflammatory markers while favorably shifting gut microbial composition and modulating liver metabolites including glutamine and ATP, suggesting a mechanism linking gut microbiota to atherosclerosis risk reduction.
Mechanism of Mulberry Leaves and Black Sesame in Alleviating Slow Transit Constipation Revealed by Multi-Omics Analysis
Researchers examined how mulberry leaves and black sesame alleviate slow transit constipation in a mouse model, measuring gut motility, microbiota composition, and intestinal gene expression. Both dietary interventions increased beneficial bacteria, enhanced gut peristalsis, and upregulated genes associated with intestinal motility, supporting their traditional use for digestive health.
