It is widely accepted that tumors alter glucose uptake to support anabolic processes required for rapid cell proliferation. Many more metabolic pathways continue to be recognized as dysregulated in cancer cells, many of which produce “onco-metabolites” with novel or unknown functions. As an example, tumors that require the serine biosynthesis pathway support the production multiple metabolites with unclear roles in tumor growth1,2. Our lab is using proteomics and metabolomics techniques to understand the functions of these metabolites and their contribution to tumor development.
