ST:STUDY_SUMMARY Buthionine sulfoximine (BSO) and radiation were co-treated to radioresistant ST:STUDY_SUMMARY TNBC cells. The level of glutathione (GSH) was significantly increased, and the ST:STUDY_SUMMARY levels of GSH synthesis-related metabolites, such as cysteine, glycine, and ST:STUDY_SUMMARY glutamine were also increased in MDA-MB-231/RR cells. In contrast, the level of ST:STUDY_SUMMARY lactic acid was significantly reduced. In addition, reactive oxygen species ST:STUDY_SUMMARY (ROS) level was decreased in MDA-MB-231/RR cells. In the lipidomic profiles of ST:STUDY_SUMMARY MDA-MB-231/RR cells, the levels of phosphatidylcholine (PC) and ST:STUDY_SUMMARY phosphatidylethanolamine (PE) were significantly increased, whereas those of ST:STUDY_SUMMARY most of the phosphatidylinositol species were significantly decreased. BSO ST:STUDY_SUMMARY sensitized MDA-MB-231/RR cells to radiotherapy, which resulted in decreased GSH ST:STUDY_SUMMARY level and increased ROS level and apoptosis. Radioresistant TNBC cells showed ST:STUDY_SUMMARY distinct metabolic and lipidomic characteristics compared to their parental ST:STUDY_SUMMARY cells. We suggested activated GSH, PC, and PE biosynthesis pathways as potential ST:STUDY_SUMMARY targets for treating radioresistant TNBC cells. Particularly, enhanced ST:STUDY_SUMMARY radiosensitivity was achieved by inhibition of GSH biosynthesis in MDA-MB-231/RR ST:STUDY_SUMMARY cells.

The CO:COLLECTION_SUMMARY cells which had grown to 80-90% confluence, were harvested by treatment with CO:COLLECTION_SUMMARY trypsin- ethylenediaminetetraacetic acid and centrifuged. To remove the residual CO:COLLECTION_SUMMARY medium, the cell pellet was washed with 1× phosphate buffered saline twice. The CO:COLLECTION_SUMMARY cells were freeze-dried and stored at −70 °C until further analysis. CO:SAMPLE_TYPE Breast cancer cells CO:STORAGE_CONDITIONS Described in summary #TREATMENT TR:TREATMENT_SUMMARY Cells at 70–80% confluency were subjected to irradiation using a ^60CO TR:TREATMENT_SUMMARY Theratron-780 teletherapy unit at a dose rate of 1.52 Gy per minute. The cells TR:TREATMENT_SUMMARY were subjected to 25 cycles of 2 Gy irradiation over 5 weeks, and the surviving TR:TREATMENT_SUMMARY cells were designated as MDA-MB-231/RR cells. TR:CELL_MEDIA DMEM supplemented with 10% FBS and 1% penicillin-streptomycin TR:CELL_ENVIR_COND A humidified incubator at 37 °C (95% air and 5% CO2) #SAMPLEPREP SP:SAMPLEPREP_SUMMARY Extraction of metabolites and intact lipid species was performed using a SP:SAMPLEPREP_SUMMARY modified Folch procedur. Briefly, 1 mL of ice-cold chloroform containing 0.1% SP:SAMPLEPREP_SUMMARY BHT and 0.5 mL of ice-cold methanol containing 0.1% BHT were added to the SP:SAMPLEPREP_SUMMARY freeze-dried cells and vortexed. The mixture were sonicated for 30 min at 4 °C SP:SAMPLEPREP_SUMMARY and incubated for 40 min on ice with shaking. Ice-cold water containing 0.1% BHT SP:SAMPLEPREP_SUMMARY (0.38 mL) was added to the mixture for phase separation, and then centrifuged. SP:SAMPLEPREP_SUMMARY The upper (methanol) and lower (chloroform) phases were dried under nitrogen gas SP:SAMPLEPREP_SUMMARY and used GC-MS and nanoESI-MS analyses, respectively. To conduct metabolic SP:SAMPLEPREP_SUMMARY profiling using GC-MS, derivatization reaction was conducted by adding 30 μL of SP:SAMPLEPREP_SUMMARY 20,000 μg/mL methoxylamine hydrochloride in pyridine, 10 μL of myristic-d27 SP:SAMPLEPREP_SUMMARY acid (300 μg/mL as an internal standard), and 50 μL of BSTFA containing 1% SP:SAMPLEPREP_SUMMARY TMCS into dried (methanol phase) sample and incubated for 60 min at 65 °C. SP:SAMPLEPREP_SUMMARY After derivatization, 15 μL of each sample was pooled for quality control (QC) SP:SAMPLEPREP_SUMMARY and analyzed in sextuplicate. To conduct metabolic profiling using nanoESI-MS, SP:SAMPLEPREP_SUMMARY dried (chloroform phase) sample was resuspended with 130 μL of buffer solution SP:SAMPLEPREP_SUMMARY (7.5 mM ammonium acetate in methanol-chloroform (9:1, v/v)) and 10 μL of each SP:SAMPLEPREP_SUMMARY resuspended sample was pooled for QC and analyzed in sextuplicate.
