Description:
Ecdysone, the major steroid hormone of Drosophila melanogaster, is known for its role in development and reproduction. Flies that are heterozygous for mutations of the ecdysone receptor exhibit increases in life-span and resistance to various stresses, with no apparent deficit in fertility or activity. A mutant involved in the biosynthesis of ecdysone displays similar effects, which are suppressed by feeding ecdysone to the flies. These observations demonstrate the importance of the ecdysone hormonal pathway, a new player in regulating longevity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Simon, Anne F -- Shih, Cindy -- Mack, Antha -- Benzer, Seymour -- AG16630/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2003 Feb 28;299(5611):1407-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology 156-29, California Institute of Technology, 1201 California Boulevard, Pasadena, CA 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12610309" target="_blank"〉PubMed〈/a〉
