Ferroptosis is an iron-dependent form of non-apoptotic cell death PR:PROJECT_SUMMARY and is associated with anti-cancer therapeutic efficacy. Further investigations PR:PROJECT_SUMMARY are required to clarify the underlying mechanisms. Ferroptosis-resistant GC cell PR:PROJECT_SUMMARY lines are constructed. Dysregulated mRNAs between ferroptosis-resistant and PR:PROJECT_SUMMARY parental cell lines are identified. The expression of SOX13/SCAF1 is manipulated PR:PROJECT_SUMMARY in GC cell lines where relevant biological and molecular analyses are performed. PR:PROJECT_SUMMARY Molecular docking and computational screening are performed to screen potential PR:PROJECT_SUMMARY inhibitors of SOX13. We show that SOX13 boosts protein remodeling of electron PR:PROJECT_SUMMARY transport chain (ETC) complexes by directly transactivating SCAF1. This leads to PR:PROJECT_SUMMARY increased supercomplexes (SCs) assembly, mitochondrial respiration, PR:PROJECT_SUMMARY mitochondrial energetics and chemo- and immune-resistance. Zanamivir, reverts PR:PROJECT_SUMMARY the ferroptosis-resistant phenotype via directly targeting SOX13 and promoting PR:PROJECT_SUMMARY TRIM25-mediated ubiquitination and degradation of SOX13. Here we show, PR:PROJECT_SUMMARY SOX13/SCAF1 are important in ferroptosis-resistance, and targeting SOX13 with PR:PROJECT_SUMMARY zanamivir has therapeutic potential. We conducted untargeted metabolomic PR:PROJECT_SUMMARY analysis of Erastin-resis SNU-668 cells transfected with shRNA-SOX13 or PR:PROJECT_SUMMARY shRNA-NC.

When collected, cells were washed by cold PBS SP:SAMPLEPREP_SUMMARY buffer twice and immediately quenched in liquid nitrogen. Tumor samples were SP:SAMPLEPREP_SUMMARY weighed and pulverized. All samples were lysed in 1 ml of −80°C extraction SP:SAMPLEPREP_SUMMARY solvent (80% methanol/water). After centrifugation (20,000g, 4°C, 15 min), SP:SAMPLEPREP_SUMMARY supernatant was transferred to a new tube, and samples were dried using a vacuum SP:SAMPLEPREP_SUMMARY centrifugal concentrator. Blood samples from patients and mice were collected SP:SAMPLEPREP_SUMMARY into BD Vacutainer blood collection tubes and placed on ice. Serum was isolated SP:SAMPLEPREP_SUMMARY by centrifugation (15,000g, 4°C, 10 min), and aliquots of 100 μl of SP:SAMPLEPREP_SUMMARY supernatant were frozen immediately at −80°C. Metabolites were reconstituted SP:SAMPLEPREP_SUMMARY in 150 μl of 80% acetonitrile/water, vortexed, and centrifuged to remove SP:SAMPLEPREP_SUMMARY insoluble material. All samples were stored at −80°C before LC-MS/MS SP:SAMPLEPREP_SUMMARY analysis. #CHROMATOGRAPHY CH:CHROMATOGRAPHY_SUMMARY Samples were separated on an amide column, using mobile phase A consists of CH:CHROMATOGRAPHY_SUMMARY water mixed with 25 mM ammonium acetate and 25 mM Ammonium hydroxide and mobile CH:CHROMATOGRAPHY_SUMMARY phase B ACN.

Set the capillary MS:MS_COMMENTS temperature at 350 °C, and S-lens at 55. 2) Build a DDA method as follows: Full MS:MS_COMMENTS scan range: 60 to 900 (m/z); resolution for MS1 and ddMS2: 70,000 and 17,500 MS:MS_COMMENTS respectively; maximum injection time for MS1 and ddMS2: 100 ms and 45 ms; MS:MS_COMMENTS automatic gain control (AGC) for MS1 and ddMS2: 3e6 and 2e5; isolation window: MS:MS_COMMENTS 1.6 m/z; normalized collision energies (NCE): 10, 17, 25 or 30, 40, 50. 3) Build MS:MS_COMMENTS a full scan method as follows: Full scan range: 60 to 900 (m/z); resolution: MS:MS_COMMENTS 140,000; maximum injection time: 100ms; automatic gain control (AGC): 3e6 ions. MS:MS_COMMENTS Raw files were submitted to Thermo Compound Discover 2.1, (CD), and processed MS:MS_COMMENTS with Untargeted Metabolomics workflow with minor modification to find and MS:MS_COMMENTS identify the differences between samples: Performs retention time alignment, MS:MS_COMMENTS unknown compound detection, and compound grouping across all samples. Predicts MS:MS_COMMENTS elemental compositions for all compounds, fills gaps across all sam ples, and MS:MS_COMMENTS hides chemical background (using Blank samples). Identifies compounds using MS:MS_COMMENTS mzCloud (ddMS2) and ChemSpider (formula or exact mass). Also performs similarity MS:MS_COMMENTS search for all com pounds with ddMS2 data using mzCloud. Maps compounds to MS:MS_COMMENTS biological pathways using KEGG database For retention time alignment, the max MS:MS_COMMENTS time shift was 2 mins, and a tolerance of 0.5 min was used for grouping unknown MS:MS_COMMENTS compounds. Mass tolerance were set as 10 ppm for feature detection and 5 ppm for MS:MS_COMMENTS compound annotation. The exact mass of each feature was submitted to ChemSpider MS:MS_COMMENTS with 4 databases selected (BioCyc; Human Metabolome Database; KEGG; LipidMAPS). MS:MS_COMMENTS Results from Compound Discover, the compound table, was exported as .xsls file, MS:MS_COMMENTS and then analysed with R.
