| Study Title | Mouse serum metabolomics |
| Study Summary | The brain and gut are intricately connected in response to various stressful stimuli. Here we describe a brain-to-gut pathway in mice that instructs intestinal stem cells (ISCs) lineage commitment via bacterial metabolic signals. Psychological stress signals from the brain trigger a sympathetic pathway to enrich gut commensal Lactobacillus, which contributes to a transferrable loss of intestinal secretory cell subtypes. Indole-3-acetate (IAA) production by Lactobacillus murinus disrupts mitochondrial bioenergetics of ISCs and blocks secretory lineage commitment. In patients with mental stress, we observe similar enrichment of IAA and Lactobacillus species associated with gut dysfunction. These findings uncover a stress-responsive brain-gut signalling mechanism that skews ISCs fate decision and could be targeted for stress-driven gut-brain comorbidities. |

Collection:
| Collection ID: | CO002799 |
| Collection Summary: | To precipitate proteins, we combined 100 μl of SERUM with 800 μl of methanol, incubated at -20 for 30 min, then centrifuged at 18000 rpm for 10 min. Subsequently, 850 μl of supernatant was transferred to a new tube and evaporated to dryness in a Thermo Savant SpeedVac. Then 200 μl of resuspension solvent methanol was added, compounds were dissolved by vortexing for 5 min and samples were clarified by centrifuged at 18000 rpm for 10 min. |
| Sample Type: | Blood (serum) |
Treatment:
| Treatment ID: | TR002815 |
| Treatment Summary: | Chronic restraint stress (RS) in mice were placed inside a plastic mouse holder for 4 h daily, from 10:00 am to 14:00 pm, and repeated for a total of 14 consecutive days. During non-stress periods, all mice were conventionally housed and allowed free access to food and water. |

| MS Comments: | Fast data-dependent acquisition (DDA) MS/MS experiments were performed. The Progenesis QI (Nonlinear Dynamics, Newcastle, UK) was used for peak picking and alignment to screen the metabolic biomarkers that displayed significant changes between the control and the fructose-treated group. Molecular identification of the assigned biomarkers was accomplished by matching the acquired precursors and fragment ions against several standard metabolome databases including the Human Metabolome Database (http://www.hmdb.ca/), MassBank (http://www.massbank.jp/index.html), and METLIN (http://metlin.scripps.edu/index.php). Partial metabolite identification was further confirmed by comparison with available standards. Metabolic pathway enrichment analysis of these identified metabolic biomarkers was carried out by MetaboAnalyst 3.0 |
