Cancer occurs when cells divide uncontrollably. In order to proliferate, cells need a lot of energy to build all the components necessary for making new cells. It is therefore not surprising that cancer cells display metabolic reorganizations tailored for their high and rapid energy demands. However, this reorganization of cancer cells is poorly understood. In order to have a global view of tumour physiology, unbiased biological screening approaches like genomics and metabolomics are very powerful.

In this context, the experiments proposed in this project will reveal metabolites that are differentially regulated in breast cancer and that could be used as biomarkers for cancer detection. Furthermore, the genomics data will reveal key players orchestrating these metabolic changes, and these players could then be targeted for therapeutic purposes. Importantly, the identification of the combined genomic and metabolic signatures of breast cancer will be a significant achievement in itself and will undoubtedly be valuable to the cancer research community in order to move forward potential therapies that would directly benefit cancer patients.
