| Study Title | Bile acid–induced gut mitochondrial dysfunction promotes Enterobacteriaceae colonization and associates with dysbiosis in Crohn's disease |
| Study Summary | Here, we investigated whether bile acids influence gut colonization by Enterobacteriaceae. In an external human dataset, we found association between mucosal Enterobacteriaceae and the expression of mitochondrial damage–related genes. In a murine model, increased intestinal BA availability enhanced colonization by E. coli in an oxygen-dependent manner. Overall, this study establishes BAs as a potential bridge that facilitates interactions between commensals and the host epithelium, laying the essential foundation for future investigations into various intestinal diseases. |

| MS Comments: | To ensure strict quality control and evaluate the performance of the instrument, 20 µL aliquots were taken from each individual sample and combined to form a quality control sample (QC). This QC sample was then injected after every five samples, which helped in assessing the stability of the instrument and the coefficient of variation (CV) associated with the detected ions. Raw data processing was performed using Progenesis QI™ software (V3.0.7600.27622) incorporating METLIN™ plugin V1.0.7642.33805 (NonLinear Dynamics, Newcastle Upon Tyne, UK). This included peak picking, alignment, normalization and integration. Statistical analysis was performed using peak area. |
