Study IDST001623
Study TitleTargeted metabolomics analysis with raffinose-rich diet in mouse ileum
Study TypeAnalysis of fructose level in ileum of stressed mouse fed with raffinose-rich diet
Study SummaryPurified diet (AIN-93G) supplemented with raffinose was prepared. The mice were maintained on the separate diet for at least 1 week before the initiation of experiment.Chronic restraint stress (RS) in mice was performed 14 days.After sacrifice, the ileum of mice were used to analysis.

Project Title:Dietary composition analysis studies
Project Type:Untargeted metabolomics analysis with two diets
Project Summary:Dietary patterns and psychosocial factors, ubiquitous part of modern lifestyle, critically shape the gut microbiota and human health. However, it remains obscure how dietary and psychosocial inputs coordinately modulate the gut microbiota and host impact. Here, we show that dietary raffinose metabolism to fructose couples stress-induced gut microbial remodeling to intestinal stem cells (ISC) renewal and epithelial homeostasis. Chow diet (CD) and purified diet (PD) confer distinct vulnerability to gut epithelial injury, microbial alternation and ISC dysfunction in chronically restrained mice. CD preferably enriches Lactobacillus reuteri, and its colonization is sufficient to rescue stress-triggered epithelial injury.
