A model called the "reverse Warburg effect" describes cells releasing energy by glycolysis, but which are not tumor cells, but stromal fibroblasts. [32] In this scenario, the stroma become corrupted by cancer cells and turn into factories for the synthesis of energy rich nutrients.
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]
The inversion to the Warburg effect is a corollary to the Warburg hypothesis or Warburg effect that was discovered in obesity. Warburg's hypothesis suggests that tumor cells proliferate quickly and aggressively by obtaining energy or ATP, through high glucose consumption and lactate production. [1]
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. [10]
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 ...
The most well known adaptation is the Warburg effect where tumors increase their uptake and utilization of glucose. Glutamine is one of the known substances to be utilized in the reverse Krebs cycle in order to produce acetyl-CoA. [14] This type of mitochondrial activity could provide a new way to identify and target cancer causing cells. [15]
