Study Title | Data from plasma metabolome analysis of APP-KI and Wild type mice treated with B. breve MCC1274 |
Study Summary | Recently, we showed that administration of B. breve MCC1274 reduced amyloid-beta production, inhibited microglial activation, and suppressed inflammatory responses in the brains of APP knock-in (AppNL-G-F) mice. To elucidate the mechanism of action of this probiotic strain in an Alzheimer's disease-like model, we orally fed 3-month-old mice with B. breve MCC1274 or saline for 4 months and comprehensively investigated metabolites in plasma using CE-FTMS and LC-TOFMS. |

Sample Preparation:
Sampleprep ID: | SP002245 |
Sampleprep Summary: | For CE-FTMS, 40 µL of plasma was added to 160 µL of methanol containing internal standards at 0°C, 120 µL of Milli-Q water was added and mixed thoroughly, and 240 µL of this mixture was added to a Millipore 5 kDa cutoff filter (ULTRAFREE MC PLHCC, HMT) at 9100 × g for 120 min at 4°C to remove macromolecules. The filtrate was evaporated to dryness under vacuum, dissolved in 40 µL Milli-Q water, and donated to HMT's ω Scan package using capillary electrophoresis Fourier transform mass spectrometry (CE-FTMS).For LC-TOFMS, 80 µL of plasma was added to 240 µL of 1% formic acid/acetonitrile containing internal standards at 0ºC. The mixture was centrifuged at 2,300 x g, 4ºC for 5 min, then centrifuged at 2,300 x g, 4ºC for 5 min, followed by centrifugation of a hybrid SPE phospholipid cartridge (30 mg/mL of hybrid SPE-phospholipid, 30 mg/mL of (SUPELCO) and filtered to remove phospholipids. The filtrate was then evaporated to dryness under nitrogen, dissolved in 80 μL of 50% isopropanol (v/v), and metabolomic analysis was performed using liquid chromatography time-of-flight mass spectrometry (LC-TOFMS). |
