In this work, gas PR:PROJECT_SUMMARY chromatography coupled with mass spectrometry (GC-MS) was employed for the PR:PROJECT_SUMMARY determination of signatures found in ER+/PR+ breast cancer cells derived from PR:PROJECT_SUMMARY MCF-7 using different extraction solvents including: A, formic acid in water; B, PR:PROJECT_SUMMARY ammonium hydroxide in water; C, ethyl acetate; D, methanol: water (1:1, v/v); PR:PROJECT_SUMMARY and E, acetonitrile: water (1:1, v/v). The greatest extraction rate and PR:PROJECT_SUMMARY diversity of metabolites occurs with extraction solvents A and E. Extraction PR:PROJECT_SUMMARY solvent D showed moderate extraction efficiency, whereas extraction solvent B PR:PROJECT_SUMMARY and C showed inferior metabolite diversity. Metabolite set enrichment analysis PR:PROJECT_SUMMARY results showed energy production pathways to be key in MCF-7 cell lines. This PR:PROJECT_SUMMARY study showed that mass spectrometry could identify key metabolites associated PR:PROJECT_SUMMARY with cancers. The highest enriched pathways were related to energy production as PR:PROJECT_SUMMARY well as Warburg effect pathways, which may shed light on how energy metabolism PR:PROJECT_SUMMARY has been hijacked to encourage tumour progression and eventually metastasis in PR:PROJECT_SUMMARY breast cancer.

In preparation for an CO:COLLECTION_SUMMARY experiment, 3 × 106 cells were cultured in each of 15 tissue culture flasks CO:COLLECTION_SUMMARY (175 cm2) and cells were incubated for three days. When the cells reach 80% CO:COLLECTION_SUMMARY confluency, they were collected by trypsinization, counted in a cell counter and CO:COLLECTION_SUMMARY each 3 ×106 cells were suspended in 1 ml phosphate-buffered saline in an CO:COLLECTION_SUMMARY Eppendorf tube. CO:SAMPLE_TYPE Breast cancer cells CO:COLLECTION_METHOD trypsinization protocol CO:STORAGE_CONDITIONS -80℃ #TREATMENT TR:TREATMENT_SUMMARY The aim of this study was to investigate the solvent extraction efficiency, so TR:TREATMENT_SUMMARY there was no cell treatment #SAMPLEPREP SP:SAMPLEPREP_SUMMARY A total of 5 triplicated MCF-7 cell culture samples were provided in Eppendorf SP:SAMPLEPREP_SUMMARY vials dissolved in PBS, and stored at 4 °C for preservation purposes. Samples SP:SAMPLEPREP_SUMMARY were centrifuged at 13000 rpm for 10 minutes at -4 °C. Supernatant was SP:SAMPLEPREP_SUMMARY discarded, and cell pellets, each containing 3 million cells, were subjected to SP:SAMPLEPREP_SUMMARY metabolomics analysis. In order to evaluate the influence of the solvents on the SP:SAMPLEPREP_SUMMARY extraction rate, samples were divided in five different extraction groups: A, SP:SAMPLEPREP_SUMMARY 0.2 % formic acid in water; B, 0.2 % ammonium hydroxide in water; C, ethyl SP:SAMPLEPREP_SUMMARY acetate; D, methanol/water (1:1, v/v); and E, acetonitrile/water (1:1, v/v). SP:SAMPLEPREP_SUMMARY Briefly, 300 µL of the extraction solvent was added to 3 million cell pellets, SP:SAMPLEPREP_SUMMARY then vortexed for 2 minutes. All samples have been stored in ice for 1 hour, SP:SAMPLEPREP_SUMMARY during which samples have been vortexed every 15 minutes. After this, cell SP:SAMPLEPREP_SUMMARY insoluble matrix was centrifuged (13000 rpm, 10 minutes, -4 °C). Supernatant SP:SAMPLEPREP_SUMMARY was collected then dried using EZ-2 Plus (GeneVac, Ipswich, UK) at 37 ± 1 °C. SP:SAMPLEPREP_SUMMARY To detect all amino acids and metabolites, all samples were derivatized with SP:SAMPLEPREP_SUMMARY methoxyamine hydrochloride and MSTFA + 1% TMCS prior to injection to GC-MS.
