| Project Title: | Untargeted metabolomics after biliary diversion surgery |
| Project Summary: | Obesity and diabetes are worldwide problems, and treatment and control are proving more difficult and expensive. Bariatric surgery is the primary method for treating these disorders. An alternative procedure, bile diversion, dysregulates the circulation of bile acids in order to minimize fatty acid absorption. It is recognized that bile acids are involved in multiple signaling cascades, however the downstream effects of their malabsorption are yet unknown. In order to investigate the effects this will have on the metabolome, an untargeted liquid chromatography-ion mobility-mass spectrometry (LC-IM-MS) method was developed and optimized. We describe a fecal metabolite extraction method for separating species in multiple dimensions, comparing relative abundances across groups, and annotating compounds when possible. Utilizing our untargeted metabolomic pipeline, we were able to detect molecules with perturbed abundance values, including secondary bile acids, which contribute to differences between the experimental metabolomic profiles. |
