Scientists have been researching cell metabolism for some decades and this is an important topic in cancer, as cancer cells seem to use energy differently from normal cells.
The study of cancer metabolism started in the 1940s, when Otto Warburg found that rapidly dividing cancer cells didn’t consume oxygen in the same way as rapidly dividing normal cells.
Nearly 10 years ago, the scientific establishment believed cancer was caused by a dysfunction of metabolism, but the idea soon became unpopular. Now, scientists are again looking at metabolism and its role in cancer and other common diseases. Metabolism is a connected network of reactions that are arranged in parallel and interact with each other in different pathways. Such parallelism can mask how genes are linked with disease traits and make it difficult to treat conditions.
Cancer cells have different metabolic requirements from their normal counterparts. Understanding the consequences of this differential metabolism requires a detailed understanding of glucose metabolism and its relation to energy production in cancer cells.
