    Core Unit Metabolomics

    Summary

    The aim of the core unit Cancer Metabolomics is to analyse changes in cellular metabolism in cancer cells. The unit is developing suitable technologies to accurately determine metabolite concentration in cancer cell lines and tumour samples by mass spectrometry (LC/MS, Thermo Fisher Q-Exactive Orbitrap). We are also establishing protocols for the labelling of cancer cells with stable isotope tracers (i.e. glucose or glutamine) for isotopomer spectral analysis (ISA) and metabolic flux analysis (MFA). These techniques allow the identification of metabolic intermediates derived from different nutrients and can reveal altered metabolic flux in cancer cells.
