Sample Preparation:

Sampleprep ID:	SP003258
Sampleprep Summary:	For untargeted metabolomics, a total of 24 samples were analyzed (n=12 Erastinresis SNU-668 cells transfected with shRNA-NC, n=12 Erastinresis SNU-668 cells transfected with shRNA-SOX13). 2 × 105 cells of adherent cells were harvested in six-well plates. When collected, cells were washed by cold PBS buffer twice and immediately quenched in liquid nitrogen. Tumor samples were weighed and pulverized. All samples were lysed in 1 ml of −80°C extraction solvent (80% methanol/water). After centrifugation (20,000g, 4°C, 15 min), supernatant was transferred to a new tube, and samples were dried using a vacuum centrifugal concentrator. Blood samples from patients and mice were collected into BD Vacutainer blood collection tubes and placed on ice. Serum was isolated by centrifugation (15,000g, 4°C, 10 min), and aliquots of 100 μl of supernatant were frozen immediately at −80°C. Metabolites were reconstituted in 150 μl of 80% acetonitrile/water, vortexed, and centrifuged to remove insoluble material. All samples were stored at −80°C before LC-MS/MS analysis.
