Study Title | Metabolomics Insights into Doxorubicin and 5-Fluorouracil Combination Therapy in Triple-Negative Breast Cancer: A Xenograft Model Study (Part 1) |
Study Type | LC/MS/MS |
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. |

Chromatography Summary: | Mobile phases A (water with 0.1% formic acid) and B (acetonitrile with 0.1% formic acid) were used with the following gradient elusion mode: 0 to 2 min, 1% B; 2 to 17 min, 1–99% B; 17 to 20 min, 99% B; 20 to 20.1 min, 99–1% B; 20.1 to 30 min, 1% B. The flow rate was 0.25 mL/min from 0 to 20 min, 0.35 mL/min from 20 min to 28.3 min, and 0.25 mL/min from 28.3 to 30 min. The sample injection volume was 10 μl, and separation occurred on a Hamilton® Intensity Solo 2 C18 column (2.1 × 100 mm, 1.8 µm) (Bruker Daltonik) at 35°C. |
