    Aging and genome maintenance: lessons from the mouse? (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-03-01
    Description: Recent progress in the science of aging is driven largely by the use of model systems, ranging from yeast and nematodes to mice. These models have revealed conservation in genetic pathways that balance energy production and its damaging by-products with pathways that preserve somatic maintenance. Maintaining genome integrity has emerged as a major factor in longevity and cell viability. Here we discuss the use of mouse models with defects in genome maintenance for understanding the molecular basis of aging in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hasty, Paul -- Campisi, Judith -- Hoeijmakers, Jan -- van Steeg, Harry -- Vijg, Jan -- AG17242/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2003 Feb 28;299(5611):1355-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Medicine, University of Texas Health Science Center, San Antonio, TX 78245, USA. hastye@uthscsa.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12610296" target="_blank"〉PubMed〈/a〉

    Molecular pathways of neurodegeneration in Parkinson's disease (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-11-01
    Description: Parkinson's disease (PD) is a complex disorder with many different causes, yet they may intersect in common pathways, raising the possibility that neuroprotective agents may have broad applicability in the treatment of PD. Current evidence suggests that mitochondrial complex I inhibition may be the central cause of sporadic PD and that derangements in complex I cause alpha-synuclein aggregation, which contributes to the demise of dopamine neurons. Accumulation and aggregation of alpha-synuclein may further contribute to the death of dopamine neurons through impairments in protein handling and detoxification. Dysfunction of parkin (a ubiquitin E3 ligase) and DJ-1 could contribute to these deficits. Strategies aimed at restoring complex I activity, reducing oxidative stress and alpha-synuclein aggregation, and enhancing protein degradation may hold particular promise as powerful neuroprotective agents in the treatment of PD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dawson, Ted M -- Dawson, Valina L -- NS38377/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2003 Oct 31;302(5646):819-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Cell Engineering, Johns Hopkins University School of Medicine, Baltimore, MD 21287, USA. tdawson@jhmi.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14593166" target="_blank"〉PubMed〈/a〉

    Genetic control of surface curvature (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-03-01
    Description: Although curvature of biological surfaces has been considered from mathematical and biophysical perspectives, its molecular and developmental basis is unclear. We have studied the cin mutant of Antirrhinum, which has crinkly rather than flat leaves. Leaves of cin display excess growth in marginal regions, resulting in a gradual introduction of negative curvature during development. This reflects a change in the shape and the progression of a cell-cycle arrest front moving from the leaf tip toward the base. CIN encodes a TCP protein and is expressed downstream of the arrest front. We propose that CIN promotes zero curvature (flatness) by making cells more sensitive to an arrest signal, particularly in marginal regions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nath, Utpal -- Crawford, Brian C W -- Carpenter, Rosemary -- Coen, Enrico -- New York, N.Y. -- Science. 2003 Feb 28;299(5611):1404-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell and Developmental Biology, John Innes Centre, Norwich Research Park, Norwich, NR4 7UH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12610308" target="_blank"〉PubMed〈/a〉

    The origins of genome complexity (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-11-25
    Description: Complete genomic sequences from diverse phylogenetic lineages reveal notable increases in genome complexity from prokaryotes to multicellular eukaryotes. The changes include gradual increases in gene number, resulting from the retention of duplicate genes, and more abrupt increases in the abundance of spliceosomal introns and mobile genetic elements. We argue that many of these modifications emerged passively in response to the long-term population-size reductions that accompanied increases in organism size. According to this model, much of the restructuring of eukaryotic genomes was initiated by nonadaptive processes, and this in turn provided novel substrates for the secondary evolution of phenotypic complexity by natural selection. The enormous long-term effective population sizes of prokaryotes may impose a substantial barrier to the evolution of complex genomes and morphologies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lynch, Michael -- Conery, John S -- New York, N.Y. -- Science. 2003 Nov 21;302(5649):1401-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Indiana University, Bloomington, IN 47405, USA. mlynch@bio.indiana.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14631042" target="_blank"〉PubMed〈/a〉

    Loss of a callose synthase results in salicylic acid-dependent disease resistance (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-08-16
    Description: Plants attacked by pathogens rapidly deposit callose, a beta-1,3-glucan, at wound sites. Traditionally, this deposition is thought to reinforce the cell wall and is regarded as a defense response. Surprisingly, here we found that powdery mildew resistant 4 (pmr4), a mutant lacking pathogen-induced callose, became resistant to pathogens, rather than more susceptible. This resistance was due to mutation of a callose synthase, resulting in a loss of the induced callose response. Double-mutant analysis indicated that blocking the salicylic acid (SA) defense signaling pathway was sufficient to restore susceptibility to pmr4 mutants. Thus, callose or callose synthase negatively regulates the SA pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nishimura, Marc T -- Stein, Monica -- Hou, Bi-Huei -- Vogel, John P -- Edwards, Herb -- Somerville, Shauna C -- New York, N.Y. -- Science. 2003 Aug 15;301(5635):969-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, Carnegie Institution, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12920300" target="_blank"〉PubMed〈/a〉
