Sections "STUDY" contain missmatched items: {('STUDY_SUMMARY', "Background: Breast cancer is one of the most prevalent malignancies and a leading cause of death among women worldwide. Among its subtypes, triple-negative breast cancer (TNBC), which poses significant clinical challenges due to its aggressive behavior and limited treatment options. Aim: This study explored the effects of doxorubicin (DOX) and 5-fluorouracil (5-FU) as monotherapies and in combination on MDA-MB-231 xenograft model. Employing advanced metabolomics analysis, the study was designed to investigate molecular alterations triggered by these treatments. Methods: State-of-the-art metabolomics analysis using Ultra-high-performance liquid chromatography-electrospray ionization quadrupole time-of-flight mass spectrometry (UHPLC-ESI-QTOF-MS) was conducted including comprehensive plasma and tumor tissue sample profiling. Results: The study explored alterations induced by DOX, 5-FU, and their combination treatment. Each treatment group exhibited unique metabolic profiles in plasma and tumor analysis. Univariate and enrichment analyses identified alterations in metabolic pathways, including glycine and serine metabolism, spermidine and spermine biosynthesis, and purine and pyrimidine pathways. The combination of DOX and 5-FU significantly influenced plasma and tumor metabolites. The comprehensive metabolic profiling of both plasma and tumor samples shed light on the intricate changes within the tumor microenvironment and their systemic implications. Conclusion: The study findings offer insights into the metabolic vulnerabilities of TNBC in vivo induced by the studied chemotherapeutics. These findings highlight the involved metabolites and metabolic pathways in the response of MDA-MB-231 cells to DOX, 5-FU, and their combination which advance our understanding of TNBC treatment strategies, offering new possibilities for enhancing therapeutic outcomes. This part of study involves comprehensive metabolomic profiling of the tumor tissue samples specifically and tumor growth assessment provide valuable insights into these treatments'' efficacy and potential synergistic effects in TNBC."), ('STUDY_SUMMARY', "Background: Breast cancer is one of the most prevalent malignancies and a leading cause of death among women worldwide.

Sections "MS" contain missmatched items: {('MS_COMMENTS', "The ESI source conditions were set with a capillary voltage of 4500 V, drying gas flow rate of 10.0 l/min at 220°C, nebulizer pressure of 2.2 bar, and the End Plate offset at 500 V. Sodium formate (10 mM) was injected at the beginning of each sample run and used as a calibrant for internal calibration during data processing. The MS acquisition process consisted of two phases. First, an auto MS scan lasting from 0 to 0.3 minutes was utilized for calibrating sodium formate. The second phase encompassed auto MS/MS scanning with CID acquisition, including fragmentation, which extended from 0.3 to 30 minutes. Both acquisition phases were conducted in positive mode at a rate of 12 Hz. The automatic mass scan range within each run spanned from 50 to 1300 m/z, with a precursor ion width of ±0.5, a cycle time of 0.5 seconds, and a threshold of 400 counts. Active exclusion was initiated after three spectra and lifted after 0.2 minutes. For MS2 acquisition, a data-dependent acquisition (DDA) approach was employed, with collision energy settings varying between 100% and 250% and being set at 20 eV. TRX-2101/RT-28-calibrants from Nova Medical Testing Inc. for the Bruker T-ReX LC-QTOF were injected before sample analysis to assess the column's performance, reversed-phase liquid chromatography (RPLC) separation, multipoint retention time calibration, and the mass spectrometer. Additionally, TRX-3112-R/MS Certified Human serum solution for Bruker T-ReX LC-QTOF (provided by Nova Medical Testing Inc.) was prepared from pooled human blood and administered before sample analysis to validate the performance of the LC-MS instruments. The analysis followed a randomized sequence order, commencing with five injections of solvent A (0.1% formic acid in deionized water) to facilitate apparatus equilibration. Subsequently, five injections of the pooled QC sample were carried out.
