The number of increased and decreased fluxes and their. Many similar alterations are also observed in rapidly proliferating normal cells, in which they represent appropriate responses to physiological growth signals as opposed to. We have known for nearly a century that the metabolism of cancer cells can differ markedly from healthy cells. Electricalchargemediated cancer cell targeting via. For example, cancer cells consume far more glucose to generate energy and to produce materials that support cell division.
The early observations of warburg and his contemporaries established that there are fundamental differences in the central metabolic pathways. The persistent activation of aerobic glycolysis in cancer cells. The altered metabolism of cancer cells is likely to imbue them with several proliferative and survival advantages, such as enabling cancer cells to execute the biosynthesis of macromolecules c, to avoid apoptosis d, and to engage in local metabolitebased paracrine and autocrine signaling e.

Notably, some metabolic enzymes and metabolites in cancer cells have recently been found to have additional functions, which are distinct from. Cancer cells adapt their metabolism to facilitate biomass formation to support their rapid proliferation.
From a therapeutic perspective, knowledge of the causes, benefits, and vulnerabilities of cancer cell metabolism will enable the identification of new drug targets and will facilitate the design of metabolite mimetics that are uniquely taken up by cancer cells or converted into the active form by enzymes upregulated in tumors.
