text: A large number of researchers have dedicated and are dedicating their efforts to the study of the Warburg effect that is intimately associated with the Warburg hypothesis. In oncology, the Warburg effect is the observation that most cancer cells predominantly produce energy by a high rate of glycolysis followed by lactic acid fermentation in the cytosol, rather than by a comparatively low rate of glycolysis followed by oxidation of pyruvate in mitochondria as in most normal cells. Interestingly, researchers found that under obesity, tumor cells invert the metabolic flow by producing glucose by gluconeogenesis using lactic acid and other metabolic sources as substrates. This process in known as Warburg effect inversion.
  In particular, almost 18,000 publications have been published on the matter of ATP and the Warburg effect in the period 2000 to 2015. Most of the functions of the Warburg Effect have been the object of study. Thousands of publications claim to have determined its functions or causes.
  Thomas N. Seyfried and Peter L. Pedersen are leading supporters of the Warburg hypothesis of the cause of cancer and consider experimental and other evidence to overwhelming favor it over the widely accepted somatic mutation theory.
