Metabolomics is a growing and powerful technology capable of detecting several of metabolites in tissues and biofluids. it is now possible to gain deeper understanding of the metabolic processes occurring within cancer cells, including how they exploit the process of glycolysis. Cancer cells are known to rely on higher rates of glycolysis, an observation that is known as the "Warburg effect". With metabolomic profiling, it is possible to relate the "Warburg effect" to the production of amino acids, nucleotides, and lipids necessary for tumour proliferation and vascularisation.
