Study ID	ST001961
Study Title	Metabolomics of brown adipose tissue in murine heart failure model
Study Type	untargeted CE-TOF/MS metabolomic profiling
Study Summary	Brown adipose tissue (BAT) was initially characterised as a thermogenic organ, and recent studies have suggested it plays a crucial role in maintaining systemic metabolic health. In this project, we demonstrated that alteration of BAT function contributes to development of heart failure through disorientation in choline metabolism. To analyze the changes of metabolites, we conducted the CE-TOF/MS analysis using BAT from TAC (thoracic aortic constriction) or sham-operated mice. In BAT from TAC-operated mice, we found increase of choline and glycerophosphorylcholine and a decrease of phosphorylcholine, suggesting that BAT dysfunction induces the disorientation of choline metabolism.

Sample Preparation:

Sampleprep ID:	SP002047
Sampleprep Summary:	To extract metabolites, 40~50mg snap-frozen samples were completely homogenized by Shake Master NEO (Bio Medical Science) in 500uL of methanol containing L-methionine sulfone (Wako 502-76641), methionine sulfone (MES, Dojindo 349-01623), and D-camphor-10-sulfonic acid sodium salt (CSA, Wako 037-01032) (all at 20 μM). After adding CHCl3 (500 μl) and distilled water (200 μl) with thorough mixing, centrifugation was performed at 4,600g for 15 min at 4°C. Then the aqueous layer (300 μl) was collected and transferred to a 5-kDa cutoff filter (UltrafreeMC-PLHCC; Human Metabolome Technologies, UFC3LCCNB-HMT). Centrifugation was performed at 9,100g for 3 hours at 20°C, after which the filtrate was centrifugally concentrated and dissolved in 50μl distilled water containing reference compounds (200 μM each of 3-aminopyrrolidine and trimesate).
