Lipid extractions were performed by slightly modifying the Matyash method. 100% ice-cold methanol (300 µL) containing 0.1% butylated hydroxytoluene and H2O(90 uL) was added in the plasma(10 uL). After adding 1 mL of methyl-tert-butyl ether with 0.1% butylated hydroxytoluene, the samples were shaken at 20 to 23°C for 1 h. In total, 250 µL of water was added and vortexed for 10 min. Thereafter, phase separation was performed via centrifugation at 14,000g for 15 min at 4°C. For targeted lipidomics analysis, the upper (220 µL) and lower (110 µL) phases were pooled and dried using N2 purge. , Lipid extractions were performed by slightly modifying the Matyash method. 75% ice-cold methanol (400 µL) containing 0.1% butylated hydroxytoluene was added in the cell(10^6). After homogenizing the cells were removed using stainless steel beads and TissueLyser (QIAGEN, Germany’s Helden). After adding 1 mL of methyl-tert-butyl ether with 0.1% butylated hydroxytoluene, the samples were shaken at 20 to 23°C for 1 h. In total, 250 µL of water was added and vortexed for 10 min.

For targeted lipidomics analysis, the upper (220 µL) and lower (110 µL) phases were pooled and dried using N2 purge.
크로마토그래피 프로토콜
Samples were analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS, LC-MS 8060, Shimadzu, Kyoto, Japan) with a Kinetex C18 column (100 x 2.1mm i.d., 2.6 μm particle size; Phenomenex, Torrance, CA, USA). Mobile phase A and B consisted of 10 mM ammonium acetate in water/methanol (1/9, v/v) and 10 mM ammonium acetate in methanol/isopropanol (1/1, v/v), respectively. The gradient elution condition was as follows: 30% B (0 min), 95% B (5 min), 95% B (15 min), 30% B (15.1 min) and 30% B (20 min). The sample injection volume was 5 μL and the flow rate was maintained at 0.2 mL/min. , Samples were analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS, LC-MS 8060, Shimadzu, Kyoto, Japan) with a Kinetex C18 column (100 x 2.1mm i.d., 2.6 μm particle size; Phenomenex, Torrance, CA, USA).
