Warburg effect (oncology)

Common card · No. 250368

In oncology, the Warburg effect () is the observation that most cancers use aerobic glycolysis and lactic acid fermentation for energy generation rather than the mechanisms used by non-cancerous cells. This observation was first published by Otto Heinrich Warburg, who was awarded the 1931 Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme". In fermentation, the last product of glycolysis, pyruvate, is converted into lactate or ethanol. While fermentation produces adenosine triphosphate (ATP) only in low yield compared to the citric acid cycle and oxidative phosphorylation of aerobic respiration, it allows proliferating cells to convert nutrients such as glucose and glutamine more efficiently into biomass by avoiding unnecessary catabolic oxidation of such nutrients into carbon dioxide, preserving carbon-carbon bonds and promoting anabolism. Diagnostically the increased glucose consumption by cancer cells resulting from the Warburg effect...
