    Retrograde viral delivery of IGF-1 prolongs survival in a mouse ALS model (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-08-09
    Description: Amyotrophic lateral sclerosis (ALS) is a progressive, lethal neuromuscular disease that is associated with the degeneration of spinal and brainstem motor neurons, leading to atrophy of limb, axial, and respiratory muscles. The cause of ALS is unknown, and there is no effective therapy. Neurotrophic factors are candidates for therapeutic evaluation in ALS. Although chronic delivery of molecules to the central nervous system has proven difficult, we recently discovered that adeno-associated virus can be retrogradely transported efficiently from muscle to motor neurons of the spinal cord. We report that insulin-like growth factor 1 prolongs life and delays disease progression, even when delivered at the time of overt disease symptoms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaspar, Brian K -- Llado, Jeronia -- Sherkat, Nushin -- Rothstein, Jeffrey D -- Gage, Fred H -- AG12992/AG/NIA NIH HHS/ -- AG21876/AG/NIA NIH HHS/ -- NS33958/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2003 Aug 8;301(5634):839-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetics, The Salk Institute for Biological Studies, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12907804" target="_blank"〉PubMed〈/a〉

    Evolutionary discrimination of mammalian conserved non-genic sequences (CNGs) (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-10-04
    Description: Analysis of the human and mouse genomes identified an abundance of conserved non-genic sequences (CNGs). The significance and evolutionary depth of their conservation remain unanswered. We have quantified levels and patterns of conservation of 191 CNGs of human chromosome 21 in 14 mammalian species. We found that CNGs are significantly more conserved than protein-coding genes and noncoding RNAS (ncRNAs) within the mammalian class from primates to monotremes to marsupials. The pattern of substitutions in CNGs differed from that seen in protein-coding and ncRNA genes and resembled that of protein-binding regions. About 0.3% to 1% of the human genome corresponds to a previously unknown class of extremely constrained CNGs shared among mammals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dermitzakis, Emmanouil T -- Reymond, Alexandre -- Scamuffa, Nathalie -- Ucla, Catherine -- Kirkness, Ewen -- Rossier, Colette -- Antonarakis, Stylianos E -- New York, N.Y. -- Science. 2003 Nov 7;302(5647):1033-5.

    Whales before whaling in the North Atlantic (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-07-26
    Description: It is well known that hunting dramatically reduced all baleen whale populations, yet reliable estimates of former whale abundances are elusive. Based on coalescent models for mitochondrial DNA sequence variation, the genetic diversity of North Atlantic whales suggests population sizes of approximately 240,000 humpback, 360,000 fin, and 265,000 minke whales. Estimates for fin and humpback whales are far greater than those previously calculated for prewhaling populations and 6 to 20 times higher than present-day population estimates. Such discrepancies suggest the need for a quantitative reevaluation of historical whale populations and a fundamental revision in our conception of the natural state of the oceans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roman, Joe -- Palumbi, Stephen R -- New York, N.Y. -- Science. 2003 Jul 25;301(5632):508-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Organismic and Evolutionary Biology, Harvard University, 16 Divinity Avenue, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12881568" 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〉

    LysM domain receptor kinases regulating rhizobial Nod factor-induced infection (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-08-30
    Description: The rhizobial infection of legumes has the most stringent demand toward Nod factor structure of all host responses, and therefore a specific Nod factor entry receptor has been proposed. The SYM2 gene identified in certain ecotypes of pea (Pisum sativum) is a good candidate for such an entry receptor. We exploited the close phylogenetic relationship of pea and the model legume Medicago truncatula to identify genes specifically involved in rhizobial infection. The SYM2 orthologous region of M. truncatula contains 15 putative receptor-like genes, of which 7 are LysM domain-containing receptor-like kinases (LYKs). Using reverse genetics in M. truncatula, we show that two LYK genes are specifically involved in infection thread formation. This, as well as the properties of the LysM domains, strongly suggests that they are Nod factor entry receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Limpens, Erik -- Franken, Carolien -- Smit, Patrick -- Willemse, Joost -- Bisseling, Ton -- Geurts, Rene -- New York, N.Y. -- Science. 2003 Oct 24;302(5645):630-3.

    Nervous system targets of RNA editing identified by comparative genomics (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-08-09
    Description: An unknown number of precursor messenger RNAs undergo genetic recoding by modification of adenosine to inosine, a reaction catalyzed by the adenosine deaminases acting on RNA (ADARs). Discovery of these edited transcripts has always been serendipitous. Using comparative genomics, we identified a phylogenetic signature of RNA editing. We report the identification and experimental verification of 16 previously unknown ADAR target genes in the fruit fly Drosophila and one in humans-more than the sum total previously reported. All of these genes are involved in rapid electrical and chemical neurotransmission, and many of the edited sites recode conserved and functionally important amino acids. These results point to a pivotal role for RNA editing in nervous system function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoopengardner, Barry -- Bhalla, Tarun -- Staber, Cynthia -- Reenan, Robert -- R01 GM062291/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Aug 8;301(5634):832-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics and Developmental Biology, University of Connecticut Health Center, 263 Farmington Avenue, Farmington, CT 06030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12907802" target="_blank"〉PubMed〈/a〉
