This observation was first published by Otto Heinrich Warburg, [2] who was awarded the 1931 Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme". [3] The existence of the Warburg effect has fuelled popular misconceptions that cancer can be treated by dietary reductions in sugar and ...
In cancer, there are several reprogrammed metabolic pathways that help cells survive when nutrients are scarce: Aerobic glycolysis, an increase in glycolytic flux, also known as the Warburg effect, allows glycolytic intermediates to supply subsidiary pathways to meet the metabolic demands of proliferating tumorigenic cells.

Scientist Otto Warburg, whose research activities led to the formulation of the Warburg hypothesis for explaining the root cause of cancer.. The Warburg hypothesis (/ ˈ v ɑːr b ʊər ɡ /), sometimes known as the Warburg theory of cancer, postulates that the driver of carcinogenesis (cancer formation) is insufficient cellular respiration caused by insult (damage) to mitochondria. [1]
Most cancer cells use alternative metabolic pathways to generate energy, a fact appreciated since the early twentieth century with the postulation of the Warburg hypothesis, [16] [17] but only now gaining renewed research interest. [18] Cancer cells exhibiting the Warburg effect upregulate glycolysis and lactic acid fermentation in the cytosol ...
High amount of aerobic glycolysis (also known as the Warburg effect) distinguishes cancer cells from normal cells.The conversion of glucose to lactate rather than metabolizing it in the mitochondria through oxidative phosphorylation, (which can also occur in hypoxic normal cells) persists in malignant tumor despite the presence of oxygen.
In cancer cells, an increase in Akt signaling correlates with an increase in glucose metabolism, compared to normal cells. Cancer cells favour glycolysis for energy production over mitochondrial oxidative phosphorylation, even when oxygen supply is not limited. This is known as the Warburg effect, or aerobic glycolysis.
It covers research on all aspects of cancer and cancer-related biomedical sciences and was established in 1941. The editor-in-chief is Chi Van Dang. [1] The journal was established in 1916 as the Journal of Cancer Research, was renamed American Journal of Cancer in 1931, and obtained its current name in 1941.
The Warburg effect is the preferential use of glycolysis for energy to sustain cancer growth. p53 has been shown to regulate the shift from the respiratory to the glycolytic pathway. [102] However, a mutation can damage the tumor suppressor gene itself, or the signal pathway that activates it, "switching it off".
