Evolutionary basis of ageing
Professor Cynthia Kenyon (University of California, San Francisco, USA) Summary: Scientists have long thought that ageing ‘just happens’. Yet because of their genes, different species have different lifespans. From the roundworm C. elegans, we now know that ageing is regulated, by specific genes. These genes also influence life span in mammals, including humans. This system, and its evolution, will be discussed. |

| Abstract: | Biography: Cynthia Kenyon graduated valedictorian in chemistry and biochemistry from the University of Georgia, USA, in 1976. She received her PhD from Massachusetts Institute of Technology in 1981, and then did postdoctoral studies with Nobel laureate Sydney Brenner at the MRC Laboratory of Molecular Biology in Cambridge, UK. Since 1986, she has been at the University of California, San Francisco. In 1993, Cynthia Kenyon’s discovery that a single-gene mutation could double the life span of the roundworm C. elegans sparked an intensive study of the molecular biology of ageing. Cynthia Kenyon’s findings have now led to the discovery that an evolutionarily conserved hormone signalling system controls ageing in other organisms as well, including mammals. She has received many awards for her work. |
