| Study Title | 2’-fucosyllactose prevents colitis |
| Study Type | untargeted metabolomics analysis |
| Study Summary | Human milk-derived 2’-fucosyllactose (2’-FL) consumption is associated with health benefits in infancy that extend into adulthood. However, the exact biological functions of 2’-FL and corresponding mechanisms of action remain largely unknown. Here, we investigated the impact of 2’-FL on gut microbial metabolism for the prevention of colitis in adulthood. The gut microbiota from adult mice treated with 2’-FL showed an increase in abundance of several health-associated genera, including Bifidobacterium, and exhibited preventive effects on colitis. Microbial metabolic analysis demonstrated that 26 pathways that are significantly different between non-inflammatory bowel disease individuals and patients with ulcerative colitis (UC) are significantly regulated by 2’-FL in mice, indicating that 2’-FL has the potential to directly regulate dysregulated microbial metabolism in UC. Exploratory metabolomics of Bifidobacterium infantis identified novel secreted metabolites significantly enriched by 2’-FL consumption, including pantothenol. Remarkably, pantothenate significantly protects mucosal barrier and mitigates colitis in adult mice. Thus 2’-FL-modulated gut microbial metabolism may contribute to the prevention of intestinal inflammation in adulthood. |

| MS Comments: | The acquired RPLC-HRMS raw data from five (5) biological replicates from each sample type were imported, processed, normalized and reviewed using Progenesis QI v.3.0 (Non-linear Dynamics, Newcastle, UK). All MS and MS/MS sample runs were aligned against a pooled QC reference run. Unique ions (retention time and m/z pairs) were de-adducted and de-isotoped to generate unique “features” (or retention time and m/z pairs). Data were normalized to all features and cleaned by removing spectral features >25% CV in the pooled QC samples. Sample process and instrument variability were also assessed to determine sample acceptance. Briefly, QA metrics for sample process variability and instrument variability are ≤10% CV and ≤5% CV, respectively. In these studies, no samples were identified as outliers. Statistical analyses were performed in Progensis QI using variance stabilized measurements achieved through log normalization to calculate p-values by one-way analysis of variance (ANOVA) test. Significantly changed metabolites were chosen with the criteria p-value <0.05 and |FC| > 2. |
