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

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.

Raw files were submitted to Thermo Compound Discover 2.1, (CD), and processed with Untargeted Metabolomics workflow with minor modification to find and identify the differences between samples: Performs retention time alignment, unknown compound detection, and compound grouping across all samples. Predicts elemental compositions for all compounds, fills gaps across all sam ples, and hides chemical background (using Blank samples). Identifies compounds using mzCloud (ddMS2) and ChemSpider (formula or exact mass). Also performs similarity search for all com pounds with ddMS2 data using mzCloud. Maps compounds to biological pathways using KEGG database For retention time alignment, the max time shift was 2 mins, and a tolerance of 0.5 min was used for grouping unknown compounds. Mass tolerance were set as 10 ppm for feature detection and 5 ppm for compound annotation. The exact mass of each feature was submitted to ChemSpider with 4 databases selected (BioCyc; Human Metabolome Database; KEGG; LipidMAPS). Results from Compound Discover, the compound table, was exported as .xsls file, and then analysed with R.
