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]
Otto Warburg postulated this change in metabolism is the fundamental cause of cancer, [8] a claim now known as the Warburg hypothesis. Today, mutations in oncogenes and tumor suppressor genes are thought to be responsible for malignant transformation , and the Warburg effect is considered to be a result of these mutations rather than a cause.
Warburg investigated the metabolism of tumors and the respiration of cells, particularly cancer cells, and in 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme". [1] In particular, he discovered that animal tumors produce large quantities of lactic acid. [6]
In the absence of hypoxic conditions (i.e. physiological levels of oxygen), cancer cells preferentially convert glucose to lactate, according to Otto H. Warburg, who believed that aerobic glycolysis was the key metabolic change in cancer cell malignancy. The "Warburg effect" was later coined to describe this metabolic shift. [6]
A few months later, Bloodgood asked Geschickter to come back and help him at the new Garvan Cancer Research Laboratory. Geschickter agreed, and before starting work made a tour of pathology laboratories in Europe, including the biochemistry unit run by Otto Heinrich Warburg in Berlin. His main interest after this was in cancer research and ...
Danielle Fishel is sharing an update about her health, saying she has completed “active cancer treatment” following her announcement in August that she was diagnosed with DCIS, which stands ...
"Alcohol is a well-established, preventable cause of cancer responsible for about 100,000 cases of cancer and 20,000 cancer deaths annually in the United States," he said in the advisory on Friday.
In 1939, he joined the Cancer Institute as a senior chemist. He was head of the cytochemistry laboratory when he retired in 1974. He also taught biochemistry at the Cornell University Medical School from 1939 to 1941. [3] He was a research master at George Washington University. Burk was a close friend and co-author with Otto Heinrich Warburg. [7]
