| 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. |

Collection:
| Collection ID: | CO003475 |
| Collection Summary: | Feces were collected aseptically from 4-8 wks old mice. Briefly, mice were placed in an empty autoclaved cage without bedding. Mice were then allowed to defecate normally and the first two fecal pellets were collected using sterile forceps, followed by snap freezing in liquid nitrogen. For processing, feces were homogenized in 100% methanol (50 mg/mL) and spun (13,500 rpm, 10 mins) to collect BA-containing supernatant. |
| Sample Type: | Feces |
