| Study Title | Chemoresistant Ovarian Cancer Global Metabolomics |
| Study Summary | Chemoresistance remains the major barrier to effective ovarian cancer treatment. The molecular features and associated biological functions of this phenotype remain poorly understood. We developed carboplatin resistant cell line models using OVCAR5 and CaOV3 cell lines with the aim of identifying chemoresistance-specific molecular features. Mass spectrometry analysis was used to analyse the metabolome of these cell lines and was able to separate these populations based on their molecular features. It revealed signaling and metabolic perturbations in chemoresistant cell lines. A comprehensive analysis of a larger patient cohort, including advanced in vitro and in vivo models, promises to help better understand the molecular mechanisms of chemo-resistance and associated enhancement of migration and invasion. |

| Chromatography Summary: | LCMS data was acquired on Q-Exactive Orbitrap mass spectrometer (Thermo Fisher) coupled with high-performance liquid chromatography (HPLC) system Dionex Ulti-mate® 3000 RS (Thermo Fisher). Chromatographic separation was performed on a ZIC-pHILIC column (5 µm, polymeric, 150 × 4.6 mm, SeQuant®, Merck). The mobile phase (A) was 20 mM ammonium carbonate and (B) acetonitrile. The gradient pro-gram started at 80% B and was reduced to 50% B over 15 min, then reduced from 50% B to 5% B over 3 min, followed by wash with 5% B for another 3 min, and finally 8 min re-equilibration with 80% B. The flow rate was 0.3 mL/min and column compartment temperature was 25 ºC. The total run time was 32 min with an injection sample vol-ume of 10 µL. Mass spectrometer operated in full scan mode with positive and nega-tive polarity switching at 35000 resolution at 200 m/z with detection range of 85 to 1, 275 m/z in full scan mode. Electro-spray ionization source (HESI) was set to 3.5 kV voltage for positive mode and 4.0 kV for negative mode, sheath gas was set to 50 and aux gas to 20 arbitrary units, capillary temperature 300 °C, probe heater temperature 120 °C. |
