    Extension of life-span with superoxide dismutase/catalase mimetics (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-09-01
    Description: We tested the theory that reactive oxygen species cause aging. We augmented the natural antioxidant systems of Caenorhabditis elegans with small synthetic superoxide dismutase/catalase mimetics. Treatment of wild-type worms increased their mean life-span by a mean of 44 percent, and treatment of prematurely aging worms resulted in normalization of their life-span (a 67 percent increase). It appears that oxidative stress is a major determinant of life-span and that it can be counteracted by pharmacological intervention.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Melov, S -- Ravenscroft, J -- Malik, S -- Gill, M S -- Walker, D W -- Clayton, P E -- Wallace, D C -- Malfroy, B -- Doctrow, S R -- Lithgow, G J -- AG-13154/AG/NIA NIH HHS/ -- NS21328/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2000 Sep 1;289(5484):1567-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Buck Institute for Age Research, Novato, CA 94949, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10968795" target="_blank"〉PubMed〈/a〉

    Checkpoint proteins control survival of the postmitotic cells in Caenorhabditis elegans (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-06-03
    Description: Checkpoints are evolutionarily conserved signaling mechanisms that arrest cell division and alter cellular stress resistance in response to DNA damage or stalled replication forks. To study the consequences of loss of checkpoint functions in whole animals, checkpoint genes were inactivated in the nematode C. elegans. We show that checkpoint proteins are not only essential for normal development but also determine adult somatic maintenance. Checkpoint proteins play a role in the survival of postmitotic adult cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2568993/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2568993/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olsen, Anders -- Vantipalli, Maithili C -- Lithgow, Gordon J -- AG21069/AG/NIA NIH HHS/ -- AG22868/AG/NIA NIH HHS/ -- NS050789-01/NS/NINDS NIH HHS/ -- R01 AG021069/AG/NIA NIH HHS/ -- R01 AG021069-04/AG/NIA NIH HHS/ -- R01 AG022868/AG/NIA NIH HHS/ -- R01 AG022868-04/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2006 Jun 2;312(5778):1381-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Buck Institute, 8001 Redwood Boulevard, Novato, CA 94945, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16741121" target="_blank"〉PubMed〈/a〉

    Mortality rates in a genetically heterogeneous population of Caenorhabditis elegans (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-02-04
    Description: Age-specific mortality rates in isogenic populations of the nematode Caenorhabditis elegans increase exponentially throughout life. In genetically heterogeneous populations, age-specific mortality increases exponentially until about 17 days and then remains constant until the last death occurs at about 60 days. This period of constant age-specific mortality results from genetic heterogeneity. Subpopulations differ in mean life-span, but they all exhibit near exponential, albeit different, rates of increase in age-specific mortality. Thus, much of the observed heterogeneity in mortality rates later in life could result from genetic heterogeneity and not from an inherent effect of aging.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brooks, A -- Lithgow, G J -- Johnson, T E -- K04-AG00369/AG/NIA NIH HHS/ -- R01-AG08332/AG/NIA NIH HHS/ -- R01-AG10248/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1994 Feb 4;263(5147):668-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Behavioral Genetics, University of Colorado, Boulder 80309.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303273" target="_blank"〉PubMed〈/a〉
