Metabolism is essential for life, and its alteration is implicated in multiple
human diseases. The transformation from a normal to a cancerous cell requires
metabolic changes to fuel the high metabolic demands of cancer cells, including
but not limited to cell proliferation and cell migration. In recent years, there
have been a number of new discoveries connecting known aberrations in oncogenic
and tumour suppressor pathways with metabolic alterations required to sustain
cell proliferation and migration. However, an understanding of the selective
advantage of these metabolic alterations is still lacking. Here, we review the
literature on mathematical models of metabolism, with an emphasis on their
contribution to the identification of the selective advantage of metabolic
phenotypes that seem otherwise wasteful or accidental. We will show how the
molecular hallmarks of cancer can be related to cell proliferation and tissue
remodelling, the two major physiological requirements for the development of a
multicellular structure. We will cover different areas such as genome-wide gene
expression analysis, flux balance models, kinetic models, reaction diffusion
models and models of the tumour microenvironment. We will also highlight current
challenges and how their resolution will help to achieve a better understanding
of cancer metabolism and the metabolic vulnerabilities of cancers.
