    Disrupted timing of discontinuous but not continuous movements by cerebellar lesions (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-31
    Description: Patients with cerebellar damage are known to exhibit deficits in the temporal control of movements. We report that these deficits are restricted to discontinuous movements. Cerebellar patients exhibited no deficit in temporal variability when producing continuous, rhythmic movements. We hypothesize that the temporal properties of continuous movements are emergent and reflect the operation of other control parameters not associated with the cerebellum. In contrast, discontinuous movements require an explicit representation of the temporal goal, a function of the cerebellum. The requirement for explicit temporal representation provides a parsimonious account of cerebellar involvement in a range of tasks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spencer, Rebecca M C -- Zelaznik, Howard N -- Diedrichsen, Jorn -- Ivry, Richard B -- NS17778/NS/NINDS NIH HHS/ -- NS30256/NS/NINDS NIH HHS/ -- NS40813/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2003 May 30;300(5624):1437-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of California, Berkeley, 3210 Tolman Hall #1650, Berkeley, CA 94720, USA. rspencer@socrates.berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12775842" target="_blank"〉PubMed〈/a〉

    Casting metal nanowires within discrete self-assembled peptide nanotubes (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-04-26
    Description: Tubular nanostructures are suggested to have a wide range of applications in nanotechnology. We report our observation of the self-assembly of a very short peptide, the Alzheimer's beta-amyloid diphenylalanine structural motif, into discrete and stiff nanotubes. Reduction of ionic silver within the nanotubes, followed by enzymatic degradation of the peptide backbone, resulted in the production of discrete nanowires with a long persistence length. The same dipeptide building block, made of D-phenylalanine, resulted in the production of enzymatically stable nanotubes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reches, Meital -- Gazit, Ehud -- New York, N.Y. -- Science. 2003 Apr 25;300(5619):625-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Microbiology and Biotechnology, George S.

    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.

    Mutations in dynein link motor neuron degeneration to defects in retrograde transport (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-06
    Description: Degenerative disorders of motor neurons include a range of progressive fatal diseases such as amyotrophic lateral sclerosis (ALS), spinal-bulbar muscular atrophy (SBMA), and spinal muscular atrophy (SMA). Although the causative genetic alterations are known for some cases, the molecular basis of many SMA and SBMA-like syndromes and most ALS cases is unknown. Here we show that missense point mutations in the cytoplasmic dynein heavy chain result in progressive motor neuron degeneration in heterozygous mice, and in homozygotes this is accompanied by the formation of Lewy-like inclusion bodies, thus resembling key features of human pathology. These mutations exclusively perturb neuron-specific functions of dynein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hafezparast, Majid -- Klocke, Rainer -- Ruhrberg, Christiana -- Marquardt, Andreas -- Ahmad-Annuar, Azlina -- Bowen, Samantha -- Lalli, Giovanna -- Witherden, Abi S -- Hummerich, Holger -- Nicholson, Sharon -- Morgan, P Jeffrey -- Oozageer, Ravi -- Priestley, John V -- Averill, Sharon -- King, Von R -- Ball, Simon -- Peters, Jo -- Toda, Takashi -- Yamamoto, Ayumu -- Hiraoka, Yasushi -- Augustin, Martin -- Korthaus, Dirk -- Wattler, Sigrid -- Wabnitz, Philipp -- Dickneite, Carmen -- Lampel, Stefan -- Boehme, Florian -- Peraus, Gisela -- Popp, Andreas -- Rudelius, Martina -- Schlegel, Juergen -- Fuchs, Helmut -- Hrabe de Angelis, Martin -- Schiavo, Giampietro -- Shima, David T -- Russ, Andreas P -- Stumm, Gabriele -- Martin, Joanne E -- Fisher, Elizabeth M C -- New York, N.Y. -- Science. 2003 May 2;300(5620):808-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurodegenerative Disease, Institute of Neurology, National Hospital for Neurology and Neurosurgery, Queen Square, London WC1N 3BG, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12730604" target="_blank"〉PubMed〈/a〉

    Enrichment of gene-coding sequences in maize by genome filtration (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-12-20
    Description: Approximately 80% of the maize genome comprises highly repetitive sequences interspersed with single-copy, gene-rich sequences, and standard genome sequencing strategies are not readily adaptable to this type of genome. Methodologies that enrich for genic sequences might more rapidly generate useful results from complex genomes. Equivalent numbers of clones from maize selected by techniques called methylation filtering and High C0t selection were sequenced to generate approximately 200,000 reads (approximately 132 megabases), which were assembled into contigs. Combination of the two techniques resulted in a sixfold reduction in the effective genome size and a fourfold increase in the gene identification rate in comparison to a nonenriched library.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whitelaw, C A -- Barbazuk, W B -- Pertea, G -- Chan, A P -- Cheung, F -- Lee, Y -- Zheng, L -- van Heeringen, S -- Karamycheva, S -- Bennetzen, J L -- SanMiguel, P -- Lakey, N -- Bedell, J -- Yuan, Y -- Budiman, M A -- Resnick, A -- Van Aken, S -- Utterback, T -- Riedmuller, S -- Williams, M -- Feldblyum, T -- Schubert, K -- Beachy, R -- Fraser, C M -- Quackenbush, J -- New York, N.Y. -- Science. 2003 Dec 19;302(5653):2118-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Institute for Genomic Research (TIGR), 9712 Medical Center Drive, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14684821" target="_blank"〉PubMed〈/a〉

    Altered patterns of sleep and behavioral adaptability in NPAS2-deficient mice (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-07-05
    Description: Animal behavior is synchronized to the 24-hour light:dark (LD) cycle by regulatory programs that produce circadian fluctuations in gene expression throughout the body. In mammals, the transcription factor CLOCK controls circadian oscillation in the suprachiasmatic nucleus of the brain; its paralog, neuronal PAS domain protein 2 (NPAS2), performs a similar function in other forebrain sites. To investigate the role of NPAS2 in behavioral manifestations of circadian rhythm, we studied locomotor activity, sleep patterns, and adaptability to both light- and restricted food-driven entrainment in NPAS2-deficient mice. Our results indicate that NPAS2 plays a substantive role in maintaining circadian behaviors in normal LD and feeding conditions and that NPAS2 is critical for adaptability to food restriction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dudley, Carol A -- Erbel-Sieler, Claudia -- Estill, Sandi Jo -- Reick, Martin -- Franken, Paul -- Pitts, SiNae -- McKnight, Steven L -- 37919/PHS HHS/ -- 4R37 MH59388/MH/NIMH NIH HHS/ -- 5T3DK07328/DK/NIDDK NIH HHS/ -- HL 64148/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2003 Jul 18;301(5631):379-83.

    Rapid evolution of egg size in captive salmon (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-03-15
    Description: Captive breeding and release programs, widely used to supplement populations of declining species, minimize juvenile mortality to achieve rapid population growth. However, raising animals in benign environments may promote traits that are adaptive in captivity but maladaptive in nature. In chinook salmon, hatchery rearing relaxes natural selection favoring large eggs, allowing fecundity selection to drive exceptionally rapid evolution of small eggs. Trends toward small eggs are also evident in natural populations heavily supplemented by hatcheries, but not in minimally supplemented populations. Unintentional selection in captivity can lead to rapid changes in critical life-history traits that may reduce the success of supplementation or reintroduction programs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heath, Daniel D -- Heath, John W -- Bryden, Colleen A -- Johnson, Rachel M -- Fox, Charles W -- New York, N.Y. -- Science. 2003 Mar 14;299(5613):1738-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Great Lakes Institute for Environmental Research and Department of Biological Sciences, University of Windsor, 401 Sunset Avenue, Windsor, Ontario N9B 3P4, Canada. dheath@uwindsor.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12637746" target="_blank"〉PubMed〈/a〉

    Whales before whaling in the North Atlantic (2003)

    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〉

    The Prp19p-associated complex in spliceosome activation (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-09-13
    Description: During spliceosome activation, a large structural rearrangement occurs that involves the release of two small nuclear RNAs, U1 and U4, and the addition of a protein complex associated with Prp19p. We show here that the Prp19p-associated complex is required for stable association of U5 and U6 with the spliceosome after U4 is dissociated. Ultraviolet crosslinking analysis revealed the existence of two modes of base pairing between U6 and the 5' splice site, as well as a switch of such base pairing from one to the other that required the Prp19p-associated complex during spliceosome activation. Moreover, a Prp19p-dependent structural change in U6 small nuclear ribonucleoprotein particles was detected that involves destabilization of Sm-like (Lsm) proteins to bring about interactions between the Lsm binding site of U6 and the intron sequence near the 5' splice site, indicating dynamic association of Lsm with U6 and a direct role of Lsm proteins in activation of the spliceosome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chan, Shih-Peng -- Kao, Der-I -- Tsai, Wei-Yu -- Cheng, Soo-Chen -- New York, N.Y. -- Science. 2003 Oct 10;302(5643):279-82.

    Demography of dietary restriction and death in Drosophila (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-09-23
    Description: Dietary restriction (DR) increases life-span in organisms from yeast to mammals, presumably by slowing the accumulation of aging-related damage. Here we show that in Drosophila, DR extends life-span entirely by reducing the short-term risk of death. Two days after the application of DR at any age for the first time, previously fully fed flies are no more likely to die than flies of the same age that have been subjected to long-term DR. DR of mammals may also reduce short-term risk of death, and hence DR instigated at any age could generate a full reversal of mortality.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mair, William -- Goymer, Patrick -- Pletcher, Scott D -- Partridge, Linda -- New York, N.Y. -- Science. 2003 Sep 19;301(5640):1731-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University College London, Darwin Building, Gower Street, London WC1E 6BT, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14500985" target="_blank"〉PubMed〈/a〉

    Low potential for climatic stress adaptation in a rainforest Drosophila species (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-07-05
    Description: The ability of sensitive rainforest species to evolve in response to climate change is largely unknown. We show that the Australian tropical rainforest fly Drosophila birchii exhibits clinal variation in desiccation resistance, but the most resistant population lacks the ability to evolve further resistance even after intense selection for over 30 generations. Parent-offspring comparisons indicate low heritable variation for this trait but high levels of genetic variation for morphology. D. birchii also exhibits abundant genetic variation at microsatellite loci. The low potential for resistance evolution highlights the importance of assessing evolutionary potential in targeted ecological traits and species from threatened habitats.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoffmann, A A -- Hallas, R J -- Dean, J A -- Schiffer, M -- New York, N.Y. -- Science. 2003 Jul 4;301(5629):100-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Environmental Stress and Adaptation Research, La Trobe University, Bundoora, Victoria 3086, Australia.

    Details
    Publication Date: 2003-09-23
    Description: In the tactile funneling illusion, the simultaneous presentation of brief stimuli at multiple points on the skin produces a single focal sensation at the center of the stimulus pattern even when no physical stimulus occurs at that site. Consistent with the funneling percept, we show with optical imaging in area 3b of the primary somatosensory cortex (SI) that simultaneous stimulation of two fingertips produces a single focal cortical activation between the single fingertip activation regions. Thus, in contrast to traditional views of the body map, topographic representation in the SI reflects the perceived rather than the physical location of peripheral stimulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Li M -- Friedman, Robert M -- Roe, Anna W -- New York, N.Y. -- Science. 2003 Oct 31;302(5646):881-5.

    Description: We collected and completely sequenced 28,469 full-length complementary DNA clones from Oryza sativa L. ssp. japonica cv. Nipponbare. Through homology searches of publicly available sequence data, we assigned tentative protein functions to 21,596 clones (75.86%). Mapping of the cDNA clones to genomic DNA revealed that there are 19,000 to 20,500 transcription units in the rice genome. Protein informatics analysis against the InterPro database revealed the existence of proteins presented in rice but not in Arabidopsis. Sixty-four percent of our cDNAs are homologous to Arabidopsis proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rice Full-Length cDNA Consortium -- National Institute of Agrobiological Sciences Rice Full-Length cDNA Project Team -- Kikuchi, Shoshi -- Satoh, Kouji -- Nagata, Toshifumi -- Kawagashira, Nobuyuki -- Doi, Koji -- Kishimoto, Naoki -- Yazaki, Junshi -- Ishikawa, Masahiro -- Yamada, Hitomi -- Ooka, Hisako -- Hotta, Isamu -- Kojima, Keiichi -- Namiki, Takahiro -- Ohneda, Eisuke -- Yahagi, Wataru -- Suzuki, Kohji -- Li, Chao Jie -- Ohtsuki, Kenji -- Shishiki, Toru -- Foundation of Advancement of International Science Genome Sequencing & Analysis Group -- Otomo, Yasuhiro -- Murakami, Kazuo -- Iida, Yoshiharu -- Sugano, Sumio -- Fujimura, Tatsuto -- Suzuki, Yutaka -- Tsunoda, Yuki -- Kurosaki, Takashi -- Kodama, Takeko -- Masuda, Hiromi -- Kobayashi, Michie -- Xie, Quihong -- Lu, Min -- Narikawa, Ryuya -- Sugiyama, Akio -- Mizuno, Kouichi -- Yokomizo, Satoko -- Niikura, Junko -- Ikeda, Rieko -- Ishibiki, Junya -- Kawamata, Midori -- Yoshimura, Akemi -- Miura, Junichirou -- Kusumegi, Takahiro -- Oka, Mitsuru -- Ryu, Risa -- Ueda, Mariko -- Matsubara, Kenichi -- RIKEN -- Kawai, Jun -- Carninci, Piero -- Adachi, Jun -- Aizawa, Katsunori -- Arakawa, Takahiro -- Fukuda, Shiro -- Hara, Ayako -- Hashizume, Wataru -- Hayatsu, Norihito -- Imotani, Koichi -- Ishii, Yoshiyuki -- Itoh, Masayoshi -- Kagawa, Ikuko -- Kondo, Shinji -- Konno, Hideaki -- Miyazaki, Ai -- Osato, Naoki -- Ota, Yoshimi -- Saito, Rintaro -- Sasaki, Daisuke -- Sato, Kenjiro -- Shibata, Kazuhiro -- Shinagawa, Akira -- Shiraki, Toshiyuki -- Yoshino, Masayasu -- Hayashizaki, Yoshihide -- Yasunishi, Ayako -- New York, N.Y. -- Science. 2003 Jul 18;301(5631):376-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, National Institute of Agrobiological Sciences, 2-1-2 Kannon-dai, Tsukuba, Ibaraki 305-8602, Japan. skikuchi@nias.affrc.go.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12869764" target="_blank"〉PubMed〈/a〉

    Description: A survey of the dog genome sequence (6.22 million sequence reads; 1.5x coverage) demonstrates the power of sample sequencing for comparative analysis of mammalian genomes and the generation of species-specific resources. More than 650 million base pairs (〉25%) of dog sequence align uniquely to the human genome, including fragments of putative orthologs for 18,473 of 24,567 annotated human genes. Mutation rates, conserved synteny, repeat content, and phylogeny can be compared among human, mouse, and dog. A variety of polymorphic elements are identified that will be valuable for mapping the genetic basis of diseases and traits in the dog.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kirkness, Ewen F -- Bafna, Vineet -- Halpern, Aaron L -- Levy, Samuel -- Remington, Karin -- Rusch, Douglas B -- Delcher, Arthur L -- Pop, Mihai -- Wang, Wei -- Fraser, Claire M -- Venter, J Craig -- New York, N.Y. -- Science. 2003 Sep 26;301(5641):1898-903.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Institute for Genomic Research, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14512627" target="_blank"〉PubMed〈/a〉

    Hox10 and Hox11 genes are required to globally pattern the mammalian skeleton (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-07-19
    Description: Mice in which all members of the Hox10 or Hox11 paralogous group are disrupted provide evidence that these Hox genes are involved in global patterning of the axial and appendicular skeleton. In the absence of Hox10 function, no lumbar vertebrae are formed. Instead, ribs project from all posterior vertebrae, extending caudally from the last thoracic vertebrae to beyond the sacral region. In the absence of Hox11 function, sacral vertebrae are not formed and instead these vertebrae assume a lumbar identity. The redundancy among these paralogous family members is so great that this global aspect of Hox patterning is not apparent in mice that are mutant for five of the six paralogous alleles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wellik, Deneen M -- Capecchi, Mario R -- New York, N.Y. -- Science. 2003 Jul 18;301(5631):363-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and University of Utah, Salt Lake City, UT 84112, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12869760" target="_blank"〉PubMed〈/a〉

    Requirement of Cks2 for the first metaphase/anaphase transition of mammalian meiosis (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-04-26
    Description: We generated mice lacking Cks2, one of two mammalian homologs of the yeast Cdk1-binding proteins, Suc1 and Cks1, and found them to be viable but sterile in both sexes. Sterility is due to failure of both male and female germ cells to progress past the first meiotic metaphase. The chromosomal events up through the end of prophase I are normal in both CKS2-/- males and females, suggesting that the phenotype is due directly to failure to enter anaphase and not a consequence of a checkpoint-mediated metaphase I arrest.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spruck, Charles H -- de Miguel, Maria P -- Smith, Adrian P L -- Ryan, Aimee -- Stein, Paula -- Schultz, Richard M -- Lincoln, A Jeannine -- Donovan, Peter J -- Reed, Steven I -- CA74224/CA/NCI NIH HHS/ -- HD22681/HD/NICHD NIH HHS/ -- HD38252/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2003 Apr 25;300(5619):647-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, MB-7, The Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12714746" target="_blank"〉PubMed〈/a〉

    Geographic barriers isolate endemic populations of hyperthermophilic archaea (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-07-26
    Description: Barriers to dispersal between populations allow them to diverge through local adaptation or random genetic drift. High-resolution multilocus sequence analysis revealed that, on a global scale, populations of hyperthermophilic microorganisms are isolated from one another by geographic barriers and have diverged over the course of their recent evolutionary history. The identification of a biogeographic pattern in the archaeon Sulfolobus challenges the current model of microbial biodiversity in which unrestricted dispersal constrains the development of global species richness.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whitaker, Rachel J -- Grogan, Dennis W -- Taylor, John W -- New York, N.Y. -- Science. 2003 Aug 15;301(5635):976-8.

    Description: Cranial radiation therapy causes a progressive decline in cognitive function that is linked to impaired neurogenesis. Chronic inflammation accompanies radiation injury, suggesting that inflammatory processes may contribute to neural stem cell dysfunction. Here, we show that neuroinflammation alone inhibits neurogenesis and that inflammatory blockade with indomethacin, a common nonsteroidal anti-inflammatory drug, restores neurogenesis after endotoxin-induced inflammation and augments neurogenesis after cranial irradiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Monje, Michelle L -- Toda, Hiroki -- Palmer, Theo D -- F30 NS04696701/NS/NINDS NIH HHS/ -- MH20016-05/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2003 Dec 5;302(5651):1760-5.

    Structural basis of a phototropin light switch (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-09-13
    Description: Phototropins are light-activated kinases important for plant responses to blue light. Light initiates signaling in these proteins by generating a covalent protein-flavin mononucleotide (FMN) adduct within sensory Per-ARNT-Sim (PAS) domains. We characterized the light-dependent changes of a phototropin PAS domain by solution nuclear magnetic resonance spectroscopy and found that an alpha helix located outside the canonical domain plays a key role in this activation process. Although this helix associates with the PAS core in the dark, photoinduced changes in the domain structure disrupt this interaction. We propose that this mechanism couples light-dependent bond formation to kinase activation and identifies a signaling pathway conserved among PAS domains.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harper, Shannon M -- Neil, Lori C -- Gardner, Kevin H -- CA90601/CA/NCI NIH HHS/ -- GM08297/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Sep 12;301(5639):1541-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Biochemistry and Pharmacology, University of Texas Southwestern Medical Center, 5323 Harry Hines Boulevard, Dallas, TX 75390-9038, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12970567" target="_blank"〉PubMed〈/a〉

    Antibody domain exchange is an immunological solution to carbohydrate cluster recognition (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-06-28
    Description: Human antibody 2G12 neutralizes a broad range of human immunodeficiency virus type 1 (HIV-1) isolates by binding an unusually dense cluster of carbohydrate moieties on the "silent" face of the gp120 envelope glycoprotein. Crystal structures of Fab 2G12 and its complexes with the disaccharide Manalpha1-2Man and with the oligosaccharide Man9GlcNAc2 revealed that two Fabs assemble into an interlocked VH domain-swapped dimer. Further biochemical, biophysical, and mutagenesis data strongly support a Fab-dimerized antibody as the prevalent form that recognizes gp120. The extraordinary configuration of this antibody provides an extended surface, with newly described binding sites, for multivalent interaction with a conserved cluster of oligomannose type sugars on the surface of gp120. The unique interdigitation of Fab domains within an antibody uncovers a previously unappreciated mechanism for high-affinity recognition of carbohydrate or other repeating epitopes on cell or microbial surfaces.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Calarese, Daniel A -- Scanlan, Christopher N -- Zwick, Michael B -- Deechongkit, Songpon -- Mimura, Yusuke -- Kunert, Renate -- Zhu, Ping -- Wormald, Mark R -- Stanfield, Robyn L -- Roux, Kenneth H -- Kelly, Jeffery W -- Rudd, Pauline M -- Dwek, Raymond A -- Katinger, Hermann -- Burton, Dennis R -- Wilson, Ian A -- AI33292/AI/NIAID NIH HHS/ -- GM46192/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Jun 27;300(5628):2065-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, The Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12829775" target="_blank"〉PubMed〈/a〉

    Regulation of flowering time by histone acetylation in Arabidopsis (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-11-01
    Description: The Arabidopsis autonomous floral-promotion pathway promotes flowering independently of the photoperiod and vernalization pathways by repressing FLOWERING LOCUS C (FLC), a MADS-box transcription factor that blocks the transition from vegetative to reproductive development. Here, we report that FLOWERING LOCUS D (FLD), one of six genes in the autonomous pathway, encodes a plant homolog of a protein found in histone deacetylase complexes in mammals. Lesions in FLD result in hyperacetylation of histones in FLC chromatin, up-regulation of FLC expression, and extremely delayed flowering. Thus, the autonomous pathway regulates flowering in part by histone deacetylation. However, not all autonomous-pathway mutants exhibit FLC hyperacetylation, indicating that multiple means exist by which this pathway represses FLC expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉He, Yuehui -- Michaels, Scott D -- Amasino, Richard M -- New York, N.Y. -- Science. 2003 Dec 5;302(5651):1751-4.

    Details
    Publication Date: 2003-04-26
    Description: Eukaryotic 2-Cys peroxiredoxins (2-Cys Prxs) not only act as antioxidants, but also appear to regulate hydrogen peroxide-mediated signal transduction. We show that bacterial 2-Cys Prxs are much less sensitive to oxidative inactivation than are eukaryotic 2-Cys Prxs. By identifying two sequence motifs unique to the sensitive 2-Cys Prxs and comparing the crystal structure of a bacterial 2-Cys Prx at 2.2 angstrom resolution with other Prx structures, we define the structural origins of sensitivity. We suggest this adaptation allows 2-Cys Prxs to act as floodgates, keeping resting levels of hydrogen peroxide low, while permitting higher levels during signal transduction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wood, Zachary A -- Poole, Leslie B -- Karplus, P Andrew -- ES00210/ES/NIEHS NIH HHS/ -- GM50389/GM/NIGMS NIH HHS/ -- R01 GM050389/GM/NIGMS NIH HHS/ -- R01 GM050389-10/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Apr 25;300(5619):650-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Biophysics, Oregon State University, Corvallis, OR 97333, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12714747" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 2003-11-15
    Description: Prefoldins (PFDs) are members of a recently identified, small-molecular weight protein family able to assemble into molecular chaperone complexes. Here we describe an unusually large member of this family, termed URI, that forms complexes with other small-molecular weight PFDs and with RPB5, a shared subunit of all three RNA polymerases. Functional analysis of the yeast and human orthologs of URI revealed that both are targets of nutrient signaling and participate in gene expression controlled by the TOR kinase. Thus, URI is a component of a signaling pathway that coordinates nutrient availability with gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gstaiger, Matthias -- Luke, Brian -- Hess, Daniel -- Oakeley, Edward J -- Wirbelauer, Christiane -- Blondel, Marc -- Vigneron, Marc -- Peter, Matthias -- Krek, Wilhelm -- New York, N.Y. -- Science. 2003 Nov 14;302(5648):1208-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Friedrich Miescher Institut, Maulbeerstrasse 66, CH-4058 Basel, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14615539" target="_blank"〉PubMed〈/a〉

    Modification of ocular defects in mouse developmental glaucoma models by tyrosinase (2003)

    Details
    Publication Date: 2003-03-08
    Description: Mutations in the cytochrome P450 family 1, subfamily B, polypeptide 1 (CYP1B1) gene are a common cause of human primary congenital glaucoma (PCG). Here we show that Cyp1b1-/- mice have ocular drainage structure abnormalities resembling those reported in human PCG patients. Using Cyp1b1-/- mice, we identified the tyrosinase gene (Tyr) as a modifier of the drainage structure phenotype, with Tyr deficiency increasing the magnitude of dysgenesis. The severe dysgenesis in eyes lacking both CYP1B1 and TYR was alleviated by administration of the tyrosinase product dihydroxyphenylalanine (l-dopa). Tyr also modified the drainage structure dysgenesis in mice with a mutant Foxc1 gene, which is also involved in PCG. These experiments raise the possibility that a tyrosinase/l-dopa pathway modifies human PCG, which could open new therapeutic avenues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Libby, Richard T -- Smith, Richard S -- Savinova, Olga V -- Zabaleta, Adriana -- Martin, Janice E -- Gonzalez, Frank J -- John, Simon W M -- CA34196/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2003 Mar 7;299(5612):1578-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Jackson Laboratory, Bar Harbor, ME 04609, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12624268" target="_blank"〉PubMed〈/a〉

    Description: In March 2003, a novel coronavirus (SARS-CoV) was discovered in association with cases of severe acute respiratory syndrome (SARS). The sequence of the complete genome of SARS-CoV was determined, and the initial characterization of the viral genome is presented in this report. The genome of SARS-CoV is 29,727 nucleotides in length and has 11 open reading frames, and its genome organization is similar to that of other coronaviruses. Phylogenetic analyses and sequence comparisons showed that SARS-CoV is not closely related to any of the previously characterized coronaviruses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rota, Paul A -- Oberste, M Steven -- Monroe, Stephan S -- Nix, W Allan -- Campagnoli, Ray -- Icenogle, Joseph P -- Penaranda, Silvia -- Bankamp, Bettina -- Maher, Kaija -- Chen, Min-Hsin -- Tong, Suxiong -- Tamin, Azaibi -- Lowe, Luis -- Frace, Michael -- DeRisi, Joseph L -- Chen, Qi -- Wang, David -- Erdman, Dean D -- Peret, Teresa C T -- Burns, Cara -- Ksiazek, Thomas G -- Rollin, Pierre E -- Sanchez, Anthony -- Liffick, Stephanie -- Holloway, Brian -- Limor, Josef -- McCaustland, Karen -- Olsen-Rasmussen, Melissa -- Fouchier, Ron -- Gunther, Stephan -- Osterhaus, Albert D M E -- Drosten, Christian -- Pallansch, Mark A -- Anderson, Larry J -- Bellini, William J -- New York, N.Y. -- Science. 2003 May 30;300(5624):1394-9.

    Description: A neuroimaging study examined the neural correlates of social exclusion and tested the hypothesis that the brain bases of social pain are similar to those of physical pain. Participants were scanned while playing a virtual ball-tossing game in which they were ultimately excluded. Paralleling results from physical pain studies, the anterior cingulate cortex (ACC) was more active during exclusion than during inclusion and correlated positively with self-reported distress. Right ventral prefrontal cortex (RVPFC) was active during exclusion and correlated negatively with self-reported distress. ACC changes mediated the RVPFC-distress correlation, suggesting that RVPFC regulates the distress of social exclusion by disrupting ACC activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eisenberger, Naomi I -- Lieberman, Matthew D -- Williams, Kipling D -- R21MH66709-01/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2003 Oct 10;302(5643):290-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Franz Hall, University of California, Los Angeles, Los Angeles, CA 90095-1563, USA. neisenbe@ucla.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14551436" target="_blank"〉PubMed〈/a〉

    Genetic analysis of a high-level vancomycin-resistant isolate of Staphylococcus aureus (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-12-04
    Description: Vancomycin is usually reserved for treatment of serious infections, including those caused by multidrug-resistant Staphylococcus aureus. A clinical isolate of S. aureus with high-level resistance to vancomycin (minimal inhibitory concentration = 1024 microg/ml) was isolated in June 2002. This isolate harbored a 57.9-kilobase multiresistance conjugative plasmid within which Tn1546 (vanA) was integrated. Additional elements on the plasmid encoded resistance to trimethoprim (dfrA), beta-lactams (blaZ), aminoglycosides (aacA-aphD), and disinfectants (qacC). Genetic analyses suggest that the long-anticipated transfer of vancomycin resistance to a methicillin-resistant S. aureus occurred in vivo by interspecies transfer of Tn1546 from a co-isolate of Enterococcus faecalis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weigel, Linda M -- Clewell, Don B -- Gill, Steven R -- Clark, Nancye C -- McDougal, Linda K -- Flannagan, Susan E -- Kolonay, James F -- Shetty, Jyoti -- Killgore, George E -- Tenover, Fred C -- N01-AI-95359/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2003 Nov 28;302(5650):1569-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Healthcare Quality Promotion, Centers for Disease Control and Prevention, Atlanta, GA 30333, USA. lweigel@cdc.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14645850" 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.

    Cell therapy of alpha-sarcoglycan null dystrophic mice through intra-arterial delivery of mesoangioblasts (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-07-12
    Description: Preclinical or clinical trials for muscular dystrophies have met with modest success, mainly because of inefficient delivery of viral vectors or donor cells to dystrophic muscles. We report here that intra-arterial delivery of wild-type mesoangioblasts, a class of vessel-associated stem cells, corrects morphologically and functionally the dystrophic phenotype of virtually all downstream muscles in adult immunocompetent alpha-sarcoglycan (alpha-SG) null mice, a model organism for limb-girdle muscular dystrophy. When mesoangioblasts isolated from juvenile dystrophic mice and transduced with a lentiviral vector expressing alpha-SG were injected into the femoral artery of dystrophic mice, they reconstituted skeletal muscle in a manner similar to that seen in wild-type cells. The success of this protocol was mainly due to widespread distribution of donor stem cells through the capillary network, a distinct advantage of this strategy over previous approaches.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sampaolesi, Maurilio -- Torrente, Yvan -- Innocenzi, Anna -- Tonlorenzi, Rossana -- D'Antona, Giuseppe -- Pellegrino, M Antonietta -- Barresi, Rita -- Bresolin, Nereo -- De Angelis, M Gabriella Cusella -- Campbell, Kevin P -- Bottinelli, Roberto -- Cossu, Giulio -- 1322/Telethon/Italy -- 463/BI/Telethon/Italy -- New York, N.Y. -- Science. 2003 Jul 25;301(5632):487-92.

    Molecular basis of metal-ion selectivity and zeptomolar sensitivity by CueR (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-09-06
    Description: The earliest of a series of copper efflux genes in Escherichia coli are controlled by CueR, a member of the MerR family of transcriptional activators. Thermodynamic calibration of CueR reveals a zeptomolar (10(-21) molar) sensitivity to free Cu+, which is far less than one atom per cell. Atomic details of this extraordinary sensitivity and selectivity for +1transition-metal ions are revealed by comparing the crystal structures of CueR and a Zn2+-sensing homolog, ZntR. An unusual buried metal-receptor site in CueR restricts the metal to a linear, two-coordinate geometry and uses helix-dipole and hydrogen-bonding interactions to enhance metal binding. This binding mode is rare among metalloproteins but well suited for an ultrasensitive genetic switch.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Changela, Anita -- Chen, Kui -- Xue, Yi -- Holschen, Jackie -- Outten, Caryn E -- O'Halloran, Thomas V -- Mondragon, Alfonso -- F32 DK61868/DK/NIDDK NIH HHS/ -- GM08382/GM/NIGMS NIH HHS/ -- GM38784/GM/NIGMS NIH HHS/ -- GM51350/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Sep 5;301(5638):1383-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Molecular Biology, and Cell Biology, Northwestern University, 2205Tech Drive, Evanston, IL 60208, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12958362" target="_blank"〉PubMed〈/a〉

    Mothers' transitions from welfare to work and the well-being of preschoolers and adolescents (2003)

    Details
    Publication Date: 2003-03-08
    Description: Results from a longitudinal study of 2402 low-income families during the recent unprecedented era of welfare reform suggest that mothers' transitions off welfare and into employment are not associated with negative outcomes for preschoolers (ages 2 to 4 years) or young adolescents (ages 10 to 14 years). Indeed, no significant associations with mothers' welfare and employment transitions were found for preschoolers, and the dominant pattern was also of few statistically significant associations for adolescents. The associations that did occur provided slight evidence that mothers' entry into the labor force was related to improvements in adolescents' mental health, whereas exits from employment were linked with teenagers' increased behavior problems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chase-Lansdale, P Lindsay -- Moffitt, Robert A -- Lohman, Brenda J -- Cherlin, Andrew J -- Coley, Rebekah Levine -- Pittman, Laura D -- Roff, Jennifer -- Votruba-Drzal, Elizabeth -- New York, N.Y. -- Science. 2003 Mar 7;299(5612):1548-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Northwestern University, Evanston, IL 60208, USA. lcl@northwestern.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12624259" target="_blank"〉PubMed〈/a〉

    Abnormal coronary function in mice deficient in alpha1H T-type Ca2+ channels (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-11-25
    Description: Calcium ion (Ca2+) influx through voltage-gated Ca2+ channels is important for the regulation of vascular tone. Activation of L-type Ca2+ channels initiates muscle contraction; however, the role of T-type Ca2+ channels (T-channels) is not clear. We show that mice deficient in the alpha1H T-type Ca2+ channel (alpha(1)3.2-null) have constitutively constricted coronary arterioles and focal myocardial fibrosis. Coronary arteries isolated from alpha(1)3.2-null arteries showed normal contractile responses, but reduced relaxation in response to acetylcholine and nitroprusside. Furthermore, acute blockade of T-channels with Ni2+ prevented relaxation of wild-type coronary arteries. Thus, Ca2+ influx through alpha1H T-type Ca2+ channels is essential for normal relaxation of coronary arteries.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Chien-Chang -- Lamping, Kathryn G -- Nuno, Daniel W -- Barresi, Rita -- Prouty, Sally J -- Lavoie, Julie L -- Cribbs, Leanne L -- England, Sarah K -- Sigmund, Curt D -- Weiss, Robert M -- Williamson, Roger A -- Hill, Joseph A -- Campbell, Kevin P -- New York, N.Y. -- Science. 2003 Nov 21;302(5649):1416-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of Iowa, Iowa City, IA 52242, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14631046" target="_blank"〉PubMed〈/a〉

    A seven-transmembrane RGS protein that modulates plant cell proliferation (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-09-23
    Description: G protein-coupled receptors (GPCRs) at the cell surface activate heterotrimeric G proteins by inducing the G protein alpha (Galpha) subunit to exchange guanosine diphosphate for guanosine triphosphate. Regulators of G protein signaling (RGS) proteins accelerate the deactivation of Galpha subunits to reduce GPCR signaling. Here we identified an RGS protein (AtRGS1) in Arabidopsis that has a predicted structure similar to a GPCR as well as an RGS box with GTPase accelerating activity. Expression of AtRGS1 complemented the pheromone supersensitivity phenotype of a yeast RGS mutant, sst2Delta. Loss of AtRGS1 increased the activity of the Arabidopsis Galpha subunit, resulting in increased cell elongation in hypocotyls in darkness and increased cell production in roots grown in light. These findings suggest that AtRGS1 is a critical modulator of plant cell proliferation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Jin-Gui -- Willard, Francis S -- Huang, Jirong -- Liang, Jiansheng -- Chasse, Scott A -- Jones, Alan M -- Siderovski, David P -- GM055316/GM/NIGMS NIH HHS/ -- GM62338/GM/NIGMS NIH HHS/ -- GM65533/GM/NIGMS NIH HHS/ -- GM65989/GM/NIGMS NIH HHS/ -- R01 GM065989/GM/NIGMS NIH HHS/ -- R01 GM065989-01/GM/NIGMS NIH HHS/ -- R01 GM065989-02/GM/NIGMS NIH HHS/ -- R01 GM065989-03/GM/NIGMS NIH HHS/ -- R01 GM065989-04/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Sep 19;301(5640):1728-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, The University of North Carolina at Chapel Hill, Chapel Hill, NC 27599-3280, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14500984" target="_blank"〉PubMed〈/a〉

    Description: DNA sequence and annotation of the entire human chromosome 7, encompassing nearly 158 million nucleotides of DNA and 1917 gene structures, are presented. To generate a higher order description, additional structural features such as imprinted genes, fragile sites, and segmental duplications were integrated at the level of the DNA sequence with medical genetic data, including 440 chromosome rearrangement breakpoints associated with disease. This approach enabled the discovery of candidate genes for developmental diseases including autism.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2882961/" 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/PMC2882961/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scherer, Stephen W -- Cheung, Joseph -- MacDonald, Jeffrey R -- Osborne, Lucy R -- Nakabayashi, Kazuhiko -- Herbrick, Jo-Anne -- Carson, Andrew R -- Parker-Katiraee, Layla -- Skaug, Jennifer -- Khaja, Razi -- Zhang, Junjun -- Hudek, Alexander K -- Li, Martin -- Haddad, May -- Duggan, Gavin E -- Fernandez, Bridget A -- Kanematsu, Emiko -- Gentles, Simone -- Christopoulos, Constantine C -- Choufani, Sanaa -- Kwasnicka, Dorota -- Zheng, Xiangqun H -- Lai, Zhongwu -- Nusskern, Deborah -- Zhang, Qing -- Gu, Zhiping -- Lu, Fu -- Zeesman, Susan -- Nowaczyk, Malgorzata J -- Teshima, Ikuko -- Chitayat, David -- Shuman, Cheryl -- Weksberg, Rosanna -- Zackai, Elaine H -- Grebe, Theresa A -- Cox, Sarah R -- Kirkpatrick, Susan J -- Rahman, Nazneen -- Friedman, Jan M -- Heng, Henry H Q -- Pelicci, Pier Giuseppe -- Lo-Coco, Francesco -- Belloni, Elena -- Shaffer, Lisa G -- Pober, Barbara -- Morton, Cynthia C -- Gusella, James F -- Bruns, Gail A P -- Korf, Bruce R -- Quade, Bradley J -- Ligon, Azra H -- Ferguson, Heather -- Higgins, Anne W -- Leach, Natalia T -- Herrick, Steven R -- Lemyre, Emmanuelle -- Farra, Chantal G -- Kim, Hyung-Goo -- Summers, Anne M -- Gripp, Karen W -- Roberts, Wendy -- Szatmari, Peter -- Winsor, Elizabeth J T -- Grzeschik, Karl-Heinz -- Teebi, Ahmed -- Minassian, Berge A -- Kere, Juha -- Armengol, Lluis -- Pujana, Miguel Angel -- Estivill, Xavier -- Wilson, Michael D -- Koop, Ben F -- Tosi, Sabrina -- Moore, Gudrun E -- Boright, Andrew P -- Zlotorynski, Eitan -- Kerem, Batsheva -- Kroisel, Peter M -- Petek, Erwin -- Oscier, David G -- Mould, Sarah J -- Dohner, Hartmut -- Dohner, Konstanze -- Rommens, Johanna M -- Vincent, John B -- Venter, J Craig -- Li, Peter W -- Mural, Richard J -- Adams, Mark D -- Tsui, Lap-Chee -- 38103/Canadian Institutes of Health Research/Canada -- P01 GM061354/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 May 2;300(5620):767-72.

    Thalamic control of visceral nociception mediated by T-type Ca2+ channels (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-10-04
    Description: Sensations from viscera, like fullness, easily become painful if the stimulus persists. Mice lacking alpha1G T-type Ca2+ channels show hyperalgesia to visceral pain. Thalamic infusion of a T-type blocker induced similar hyperalgesia in wild-type mice. In response to visceral pain, the ventroposterolateral thalamic neurons evokeda surge of single spikes, which then slowly decayed as T type-dependent burst spikes gradually increased. In alpha1G-deficient neurons, the single-spike response persisted without burst spikes. These results indicate that T-type Ca2+ channels underlie an antinociceptive mechanism operating in the thalamus andsupport the idea that burst firing plays a critical role in sensory gating in the thalamus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Daesoo -- Park, Donghyun -- Choi, Soonwook -- Lee, Sukchan -- Sun, Minjeong -- Kim, Chanki -- Shin, Hee-Sup -- New York, N.Y. -- Science. 2003 Oct 3;302(5642):117-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Creative Research Initiative Center for Calcium and Learning, Korea Institutes of Science and Technology, Seoul 136-791, Korea.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14526084" target="_blank"〉PubMed〈/a〉

    SIR1, an upstream component in auxin signaling identified by chemical genetics (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-08-02
    Description: Auxin is a plant hormone that regulates many aspects of plant growth and development. We used a chemical genetics approach to identify SIR1, a regulator of many auxin-inducible genes. The sir1 mutant was resistant to sirtinol, a small molecule that activates many auxin-inducible genes and promotes auxin-related developmental phenotypes. SIR1 is predicted to encode a protein composed of a ubiquitin-activating enzyme E1-like domain and a Rhodanese-like domain homologous to that of prolyl isomerase. We suggest a molecular context for how the auxin signal is propagated to exert its biological effects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhao, Yunde -- Dai, Xinhua -- Blackwell, Helen E -- Schreiber, Stuart L -- Chory, Joanne -- 1R01GM68631-01/GM/NIGMS NIH HHS/ -- 2R01GM52413/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Aug 22;301(5636):1107-10.

    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〉

    SCNM1, a putative RNA splicing factor that modifies disease severity in mice (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-08-16
    Description: The severity of many inherited disorders is influenced by genetic background. We describe a modifier interaction in C57BL/6Jmice that converts a chronic movement disorder into a lethal neurological disease. The primary mutation (medJ) changes a splice donor site of the sodium channel gene Scn8a (Nav1.6). The modifier mutation is characteristic of strain C57BL/6Jand introduces a nonsense codon into sodium channel modifier 1 (SCNM1), a zinc finger protein and a putative splice factor. An internally deleted SCNM1 protein is also predicted as a result of exon skipping associated with disruption of a consensus exonic splicing enhancer. The effect of the modifier mutation is to reduce the abundance of correctly spliced sodium channel transcripts below the threshold for survival. Our finding that genetic variation in a putative RNA splicing factor influences disease susceptibility in mice raises the possibility that a similar mechanism modifies the severity of human inherited disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Buchner, David A -- Trudeau, Michelle -- Meisler, Miriam H -- GM24872/GM/NIGMS NIH HHS/ -- T32 DC00011/DC/NIDCD NIH HHS/ -- T32 GM07544/GM/NIGMS NIH HHS/ -- T32 HG00040/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2003 Aug 15;301(5635):967-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Human Genetics, University of Michigan School of Medicine, Ann Arbor, MI 48109-0618, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12920299" target="_blank"〉PubMed〈/a〉

    Publication Date: 2003-08-16
    Description: Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has dramatically increased the incidence of tuberculosis (TB) in subSaharan Africa, where up to 60% of TB patients are coinfected with HIV and each year 200,000 TB deaths are attributable to HIV coinfection. Now HIV threatens control of TB in Asia, Eastern Europe, and Latin America. Antiretroviral (ARV) drugs can prevent TB by preserving immunity, but cohort analysis shows that early therapy, plus high levels of coverage and compliance, will be needed to avert a significant fraction of TB cases. However, ARV drugs could enhance the treatment of TB, and TB programs provide an important entry point for the treatment of HIV/AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, Brian G -- Dye, Christopher -- New York, N.Y. -- Science. 2003 Sep 12;301(5639):1535-7.

    Kin discrimination and the benefit of helping in cooperatively breeding vertebrates (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-10-25
    Description: In many cooperatively breeding vertebrates, a dominant breeding pair is assisted in offspring care by nonbreeding helpers. A leading explanation for this altruistic behavior is Hamilton's idea that helpers gain indirect fitness benefits by rearing relatives (kin selection). Many studies have shown that helpers typically provide care for relatives, but relatively few have shown that helpers provide closer kin with preferential care (kin discrimination), fueling the suggestion that kin selection only poorly accounts for the evolution of cooperative breeding in vertebrates. We used meta-analysis to show that (i) individuals consistently discriminate between kin, and (ii) stronger discrimination occurs in species where the benefits of helping are greater. These results suggest a general role for kin selection and that the relative importance of kin selection varies across species, as predicted by Hamilton's rule.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Griffin, Ashleigh S -- West, Stuart A -- New York, N.Y. -- Science. 2003 Oct 24;302(5645):634-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Cell, Animal and Population Biology, University of Edinburgh, King's Buildings, West Mains Road, Edinburgh EH9 3JT, UK. a.griffin@ed.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14576431" target="_blank"〉PubMed〈/a〉

    Spongiform degeneration in mahoganoid mutant mice (2003)

    Details
    Publication Date: 2003-02-01
    Description: mahoganoid is a mouse coat-color mutation whose pigmentary phenotype and genetic interactions resemble those of Attractin (Atrn). Atrn mutations also cause spongiform neurodegeneration. Here, we show that a null mutation for mahoganoid causes a similar age-dependent neuropathology that includes many features of prion diseases but without accumulation of protease-resistant prion protein. The gene mutated in mahoganoid encodes a RING-containing protein with E3 ubiquitin ligase activity in vitro. Similarities in phenotype, expression, and genetic interactions suggest that mahoganoid and Atrn genes are part of a conserved pathway for regulated protein turnover whose function is essential for neuronal viability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉He, Lin -- Lu, Xin-Yun -- Jolly, Aaron F -- Eldridge, Adam G -- Watson, Stanley J -- Jackson, Peter K -- Barsh, Gregory S -- Gunn, Teresa M -- New York, N.Y. -- Science. 2003 Jan 31;299(5607):710-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, Department of Genetics, Howard Hughes Medical Institute, Stanford University School of Medicine, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12560552" target="_blank"〉PubMed〈/a〉

    Publication Date: 2003-10-11
    Description: The stone-like otoliths from the ears of teleost fishes are involved in balance and hearing and consist of calcium carbonate crystallites embedded in a protein framework. We report that a previously unknown gene, starmaker, is required in zebrafish for otolith morphogenesis. Reduction of starmaker activity by injection of modified antisense oligonucleotides causes a change in the crystal lattice structure and thus a change in otolith morphology. The expression pattern of starmaker, along with the presence of the protein on the growing otolith, suggest that the expression levels of starmaker control the shape of the otoliths.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sollner, Christian -- Burghammer, Manfred -- Busch-Nentwich, Elisabeth -- Berger, Jurgen -- Schwarz, Heinz -- Riekel, Christian -- Nicolson, Teresa -- New York, N.Y. -- Science. 2003 Oct 10;302(5643):282-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institut fur Entwicklungsbiologie, Spemannstrasse 35, 72076 Tubingen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14551434" target="_blank"〉PubMed〈/a〉

    Description: A novel coronavirus (SCoV) is the etiological agent of severe acute respiratory syndrome (SARS). SCoV-like viruses were isolated from Himalayan palm civets found in a live-animal market in Guangdong, China. Evidence of virus infection was also detected in other animals (including a raccoon dog, Nyctereutes procyonoides) and in humans working at the same market. All the animal isolates retain a 29-nucleotide sequence that is not found in most human isolates. The detection of SCoV-like viruses in small, live wild mammals in a retail market indicates a route of interspecies transmission, although the natural reservoir is not known.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guan, Y -- Zheng, B J -- He, Y Q -- Liu, X L -- Zhuang, Z X -- Cheung, C L -- Luo, S W -- Li, P H -- Zhang, L J -- Guan, Y J -- Butt, K M -- Wong, K L -- Chan, K W -- Lim, W -- Shortridge, K F -- Yuen, K Y -- Peiris, J S M -- Poon, L L M -- New York, N.Y. -- Science. 2003 Oct 10;302(5643):276-8.

    Influence of life stress on depression: moderation by a polymorphism in the 5-HTT gene (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-07-19
    Description: In a prospective-longitudinal study of a representative birth cohort, we tested why stressful experiences lead to depression in some people but not in others. A functional polymorphism in the promoter region of the serotonin transporter (5-HT T) gene was found to moderate the influence of stressful life events on depression. Individuals with one or two copies of the short allele of the 5-HT T promoter polymorphism exhibited more depressive symptoms, diagnosable depression, and suicidality in relation to stressful life events than individuals homozygous for the long allele. This epidemiological study thus provides evidence of a gene-by-environment interaction, in which an individual's response to environmental insults is moderated by his or her genetic makeup.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Caspi, Avshalom -- Sugden, Karen -- Moffitt, Terrie E -- Taylor, Alan -- Craig, Ian W -- Harrington, HonaLee -- McClay, Joseph -- Mill, Jonathan -- Martin, Judy -- Braithwaite, Antony -- Poulton, Richie -- MH45070/MH/NIMH NIH HHS/ -- MH49414/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2003 Jul 18;301(5631):386-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Social, Genetic, and Developmental Psychiatry Research Centre, Institute of Psychiatry, King's College London, PO80 De Crespigny Park, London, SE5 8AF, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12869766" target="_blank"〉PubMed〈/a〉

    Mitochondrial biogenesis in mammals: the role of endogenous nitric oxide (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-02-08
    Description: Nitric oxide was found to trigger mitochondrial biogenesis in cells as diverse as brown adipocytes and 3T3-L1, U937, and HeLa cells. This effect of nitric oxide was dependent on guanosine 3',5'-monophosphate (cGMP) and was mediated by the induction of peroxisome proliferator-activated receptor gamma coactivator 1alpha, a master regulator of mitochondrial biogenesis. Moreover, the mitochondrial biogenesis induced by exposure to cold was markedly reduced in brown adipose tissue of endothelial nitric oxide synthase null-mutant (eNOS-/-) mice, which had a reduced metabolic rate and accelerated weight gain as compared to wild-type mice. Thus, a nitric oxide-cGMP-dependent pathway controls mitochondrial biogenesis and body energy balance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nisoli, Enzo -- Clementi, Emilio -- Paolucci, Clara -- Cozzi, Valeria -- Tonello, Cristina -- Sciorati, Clara -- Bracale, Renata -- Valerio, Alessandra -- Francolini, Maura -- Moncada, Salvador -- Carruba, Michele O -- New York, N.Y. -- Science. 2003 Feb 7;299(5608):896-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Preclinical Sciences, Center for Study and Research on Obesity, Luigi Sacco Hospital, University of Milan, Milan 20157, Italy. enzo.nisoli@unimi.it〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12574632" target="_blank"〉PubMed〈/a〉

    Environmental noise retards auditory cortical development (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-04-19
    Description: The mammalian auditory cortex normally undergoes rapid and progressive functional maturation. Here we show that rearing infant rat pups in continuous, moderate-level noise delayed the emergence of adultlike topographic representational order and the refinement of response selectivity in the primary auditory cortex (A1) long beyond normal developmental benchmarks. When those noise-reared adult rats were subsequently exposed to a pulsed pure-tone stimulus, A1 rapidly reorganized, demonstrating that exposure-driven plasticity characteristic of the critical period was still ongoing. These results demonstrate that A1 organization is shaped by a young animal's exposure to salient, structured acoustic inputs-and implicate noise as a risk factor for abnormal child development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, Edward F -- Merzenich, Michael M -- NS-10414/NS/NINDS NIH HHS/ -- NS-38416/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2003 Apr 18;300(5618):498-502.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉W.

    Drosophila BLM in double-strand break repair by synthesis-dependent strand annealing (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-01-11
    Description: Bloom syndrome, characterized by a predisposition to cancer, is caused by mutation of the RecQ DNA helicase gene BLM. The precise function of BLM remains unclear. Previous research suggested that Drosophila BLM functions in the repair of DNA double-strand breaks. Most double-strand breaks in flies are repaired by homologous recombination through the synthesis-dependent strand-annealing pathway. Here, we demonstrate that Drosophila BLM mutants are severely impaired in their ability to carry out repair DNA synthesis during synthesis-dependent strand annealing. Consequently, repair in the mutants is completed by error-prone pathways that create large deletions. These results suggest a model in which BLM maintains genomic stability by promoting efficient repair DNA synthesis and thereby prevents double-strand break repair by less precise pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adams, Melissa D -- McVey, Mitch -- Sekelsky, Jeff J -- GM000678/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Jan 10;299(5604):265-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12522255" target="_blank"〉PubMed〈/a〉

    The neural basis of economic decision-making in the Ultimatum Game (2003)

    Details
    Publication Date: 2003-06-14
    Description: The nascent field of neuroeconomics seeks to ground economic decision making in the biological substrate of the brain. We used functional magnetic resonance imaging of Ultimatum Game players to investigate neural substrates of cognitive and emotional processes involved in economic decision-making. In this game, two players split a sum of money;one player proposes a division and the other can accept or reject this. We scanned players as they responded to fair and unfair proposals. Unfair offers elicited activity in brain areas related to both emotion (anterior insula) and cognition (dorsolateral prefrontal cortex). Further, significantly heightened activity in anterior insula for rejected unfair offers suggests an important role for emotions in decision-making.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sanfey, Alan G -- Rilling, James K -- Aronson, Jessica A -- Nystrom, Leigh E -- Cohen, Jonathan D -- New York, N.Y. -- Science. 2003 Jun 13;300(5626):1755-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for the Study of Brain, Mind and Behavior, Princeton University, Princeton, NJ 08544, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12805551" target="_blank"〉PubMed〈/a〉

    Glycosylation restores survival of chilled blood platelets (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-09-13
    Description: Cooling of blood platelets clusters the von Willebrand factor receptor complex. Macrophage alphaMbeta2 integrins bind to the GPIbalpha subunit of the clustered complex, resulting in rapid clearance of transfused, cooled platelets. This precludes refrigeration of platelets for transfusion, but the current practice of room temperature storage has major drawbacks. We document that alphaMbeta2 is a lectin that recognizes exposed beta-N-acetylglucosamine residues of N-linked glycans on GPIbalpha. Enzymatic galactosylation of chilled platelets blocks alphaMbeta2 recognition, prolonging the circulation of functional cooled platelets. Platelet-associated galactosyltransferase produces efficient galactosylation when uridine diphosphate-galactose is added, affording a potentially simple method for storing platelets in the cold.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoffmeister, Karin M -- Josefsson, Emma C -- Isaac, Natasha A -- Clausen, Henrik -- Hartwig, John H -- Stossel, Thomas P -- HL19429/HL/NHLBI NIH HHS/ -- HL56949/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2003 Sep 12;301(5639):1531-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology, Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115, USA. khoffmeister@rics.bwh.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12970565" target="_blank"〉PubMed〈/a〉

    Crystal structure of the carboxyltransferase domain of acetyl-coenzyme A carboxylase (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-03-29
    Description: Acetyl-coenzyme A carboxylases (ACCs) are required for the biosynthesis and oxidation of long-chain fatty acids. They are targets for therapeutics against obesity and diabetes, and several herbicides function by inhibiting their carboxyltransferase (CT) domain. We determined the crystal structure of the free enzyme and the coenzyme A complex of yeast CT at 2.7 angstrom resolution and found that it comprises two domains, both belonging to the crotonase/ClpP superfamily. The active site is at the interface of a dimer. Mutagenesis and kinetic studies reveal the functional roles of conserved residues here. The herbicides target the active site of CT, providing a lead for inhibitor development against human ACCs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Hailong -- Yang, Zhiru -- Shen, Yang -- Tong, Liang -- New York, N.Y. -- Science. 2003 Mar 28;299(5615):2064-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Columbia University, New York, NY 10027, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12663926" target="_blank"〉PubMed〈/a〉

    Positional cloning of the human quantitative trait locus underlying taste sensitivity to phenylthiocarbamide (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-02-22
    Description: The ability to taste the substance phenylthiocarbamide (PTC) has been widely used for genetic and anthropological studies, but genetic studies have produced conflicting results and demonstrated complex inheritance for this trait. We have identified a small region on chromosome 7q that shows strong linkage disequilibrium between single-nucleotide polymorphism (SNP) markers and PTC taste sensitivity in unrelated subjects. This region contains a single gene that encodes a member of the TAS2R bitter taste receptor family. We identified three coding SNPs giving rise to five haplotypes in this gene worldwide. These haplotypes completely explain the bimodal distribution of PTC taste sensitivity, thus accounting for the inheritance of the classically defined taste insensitivity and for 55 to 85% of the variance in PTC sensitivity. Distinct phenotypes were associated with specific haplotypes, which demonstrates that this gene has a direct influence on PTC taste sensitivity and that sequence variants at different sites interact with each other within the encoded gene product.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Un-kyung -- Jorgenson, Eric -- Coon, Hilary -- Leppert, Mark -- Risch, Neil -- Drayna, Dennis -- M01-RR00064/RR/NCRR NIH HHS/ -- T32 HG00044/HG/NHGRI NIH HHS/ -- Z01-000046-04/PHS HHS/ -- New York, N.Y. -- Science. 2003 Feb 21;299(5610):1221-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute on Deafness and Other Communication Disorders, National Institutes of Health, 5 Research Court, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12595690" target="_blank"〉PubMed〈/a〉

    Breast and ovarian cancer risks due to inherited mutations in BRCA1 and BRCA2 (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-10-25
    Description: Risks of breast and ovarian cancer were determined for Ashkenazi Jewish women with inherited mutations in the tumor suppressor genes BRCA1 and BRCA2. We selected 1008 index cases, regardless of family history of cancer, and carried out molecular analysis across entire families. The lifetime risk of breast cancer among female mutation carriers was 82%, similar to risks in families with many cases. Risks appear to be increasing with time: Breast cancer risk by age 50 among mutation carriers born before 1940 was 24%, but among those born after 1940 it was 67%. Lifetime risks of ovarian cancer were 54% for BRCA1 and 23% for BRCA2 mutation carriers. Physical exercise and lack of obesity in adolescence were associated with significantly delayed breast cancer onset.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉King, Mary-Claire -- Marks, Joan H -- Mandell, Jessica B -- New York Breast Cancer Study Group -- New York, N.Y. -- Science. 2003 Oct 24;302(5645):643-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Medicine and Genome Sciences, University of Washington, Seattle, WA 98195, USA. mcking@u.washington.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14576434" target="_blank"〉PubMed〈/a〉

    Talin binding to integrin beta tails: a final common step in integrin activation (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-10-04
    Description: Control of integrin affinity for ligands (integrin activation) is essential for normal cell adhesion, migration, and assembly of an extracellular matrix. Integrin activation is usually mediated through the integrin beta subunit cytoplasmic tail and can be regulated by many different biochemical signaling pathways. We report that specific binding of the cytoskeletal protein talin to integrin beta subunit cytoplasmic tails leads to the conformational rearrangements of integrin extracellular domains that increase their affinity. Thus, regulated binding of talin to integrin beta tails is a final common element of cellular signaling cascades that control integrin activation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tadokoro, Seiji -- Shattil, Sanford J -- Eto, Koji -- Tai, Vera -- Liddington, Robert C -- de Pereda, Jose M -- Ginsberg, Mark H -- Calderwood, David A -- New York, N.Y. -- Science. 2003 Oct 3;302(5642):103-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, The Scripps Research Institute, The Burnham Institute, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14526080" target="_blank"〉PubMed〈/a〉

    Intracellular bacterial biofilm-like pods in urinary tract infections (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-07-05
    Description: Escherichia coli entry into the bladder is met with potent innate defenses, including neutrophil influx and epithelial exfoliation. Bacterial subversion of innate responses involves invasion into bladder superficial cells. We discovered that the intracellular bacteria matured into biofilms, creating pod-like bulges on the bladder surface. Pods contained bacteria encased in a polysaccharide-rich matrix surrounded by a protective shell of uroplakin. Within the biofilm, bacterial structures interacted extensively with the surrounding matrix, and biofilm associated factors had regional variation in expression. The discovery of intracellular biofilm-like pods explains how bladder infections can persist in the face of robust host defenses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderson, Gregory G -- Palermo, Joseph J -- Schilling, Joel D -- Roth, Robyn -- Heuser, John -- Hultgren, Scott J -- AI29549/AI/NIAID NIH HHS/ -- AI48689/AI/NIAID NIH HHS/ -- DK51406/DK/NIDDK NIH HHS/ -- DK64540/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2003 Jul 4;301(5629):105-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Microbiology, Washington University School of Medicine, 660 South Euclid Avenue, St. Louis, MO 63110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12843396" target="_blank"〉PubMed〈/a〉

    Coronavirus main proteinase (3CLpro) structure: basis for design of anti-SARS drugs (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-15
    Description: A novel coronavirus has been identified as the causative agent of severe acute respiratory syndrome (SARS). The viral main proteinase (Mpro, also called 3CLpro), which controls the activities of the coronavirus replication complex, is an attractive target for therapy. We determined crystal structures for human coronavirus (strain 229E) Mpro and for an inhibitor complex of porcine coronavirus [transmissible gastroenteritis virus (TGEV)] Mpro, and we constructed a homology model for SARS coronavirus (SARS-CoV) Mpro. The structures reveal a remarkable degree of conservation of the substrate-binding sites, which is further supported by recombinant SARS-CoV Mpro-mediated cleavage of a TGEV Mpro substrate. Molecular modeling suggests that available rhinovirus 3Cpro inhibitors may be modified to make them useful for treating SARS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anand, Kanchan -- Ziebuhr, John -- Wadhwani, Parvesh -- Mesters, Jeroen R -- Hilgenfeld, Rolf -- New York, N.Y. -- Science. 2003 Jun 13;300(5626):1763-7.

    Dilated cardiomyopathy and heart failure caused by a mutation in phospholamban (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-03-01
    Description: Molecular etiologies of heart failure, an emerging cardiovascular epidemic affecting 4.7 million Americans and costing 17.8 billion health-care dollars annually, remain poorly understood. Here we report that an inherited human dilated cardiomyopathy with refractory congestive heart failure is caused by a dominant Arg --〉 Cys missense mutation at residue 9 (R9C) in phospholamban (PLN), a transmembrane phosphoprotein that inhibits the cardiac sarcoplasmic reticular Ca2+-adenosine triphosphatase (SERCA2a) pump. Transgenic PLN(R9C) mice recapitulated human heart failure with premature death. Cellular and biochemical studies revealed that, unlike wild-type PLN, PLN(R9C) did not directly inhibit SERCA2a. Rather, PLN(R9C) trapped protein kinase A (PKA), which blocked PKA-mediated phosphorylation of wild-type PLN and in turn delayed decay of calcium transients in myocytes. These results indicate that myocellular calcium dysregulation can initiate human heart failure-a finding that may lead to therapeutic opportunities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmitt, Joachim P -- Kamisago, Mitsuhiro -- Asahi, Michio -- Li, Guo Hua -- Ahmad, Ferhaan -- Mende, Ulrike -- Kranias, Evangelia G -- MacLennan, David H -- Seidman, J G -- Seidman, Christine E -- New York, N.Y. -- Science. 2003 Feb 28;299(5611):1410-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School and Howard Hughes Medical Institute, 200 Longwood Avenue, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12610310" target="_blank"〉PubMed〈/a〉

    COMT val158met genotype affects mu-opioid neurotransmitter responses to a pain stressor (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-02-22
    Description: Responses to pain and other stressors are regulated by interactions between multiple brain areas and neurochemical systems. We examined the influence of a common functional genetic polymorphism affecting the metabolism of catecholamines on the modulation of responses to sustained pain in humans. Individuals homozygous for the met158 allele of the catechol-O-methyltransferase (COMT) polymorphism (val158met) showed diminished regional mu-opioid system responses to pain compared with heterozygotes. These effects were accompanied by higher sensory and affective ratings of pain and a more negative internal affective state. Opposite effects were observed in val158 homozygotes. The COMT val158met polymorphism thus influences the human experience of pain and may underlie interindividual differences in the adaptation and responses to pain and other stressful stimuli.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zubieta, Jon-Kar -- Heitzeg, Mary M -- Smith, Yolanda R -- Bueller, Joshua A -- Xu, Ke -- Xu, Yanjun -- Koeppe, Robert A -- Stohler, Christian S -- Goldman, David -- R01 DE 12059/DE/NIDCR NIH HHS/ -- R01 DE 12743/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 2003 Feb 21;299(5610):1240-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry and Mental Health Research Institute, University of Michigan, Ann Arbor, MI 48109-0720, USA. zubieta@umich.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12595695" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-10-11
    Description: The genomes of several nonphotosynthetic bacteria, such as Bacillus subtilis, and some Archaea include genes for proteins with sequence homology to the large subunit of ribulose bisphosphate carboxylase/oxygenase (RuBisCO). We found that such a RuBisCO-like protein (RLP) from B. subtilis catalyzed the 2,3-diketo-5-methylthiopentyl-1-phosphate enolase reaction in the methionine salvage pathway. A growth-defective mutant, in which the gene for this RLP had been disrupted, was rescued by the gene for RuBisCOfrom the photosynthetic bacterium Rhodospirillum rubrum. Thus, the photosynthetic RuBisCO from R. rubrum retains the ability to function in the methionine salvage pathway in B. subtilis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ashida, Hiroki -- Saito, Yohtaro -- Kojima, Chojiro -- Kobayashi, Kazuo -- Ogasawara, Naotake -- Yokota, Akiho -- New York, N.Y. -- Science. 2003 Oct 10;302(5643):286-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate School of Biological Sciences, Nara Institute of Science and Technology (NAIST), 8916-5 Takayama, Ikoma, Nara 630-0101, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14551435" target="_blank"〉PubMed〈/a〉

    Description: Continuation of mammalian species requires the formation and development of the sexually dimorphic germ cells. Cultured embryonic stem cells are generally considered pluripotent rather than totipotent because of the failure to detect germline cells under differentiating conditions. Here we show that mouse embryonic stem cells in culture can develop into oogonia that enter meiosis, recruit adjacent cells to form follicle-like structures, and later develop into blastocysts. Oogenesis in culture should contribute to various areas, including nuclear transfer and manipulation of the germ line, and advance studies on fertility treatment and germ and somatic cell interaction and differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hubner, Karin -- Fuhrmann, Guy -- Christenson, Lane K -- Kehler, James -- Reinbold, Rolland -- De La Fuente, Rabindranath -- Wood, Jennifer -- Strauss, Jerome F 3rd -- Boiani, Michele -- Scholer, Hans R -- 1RO1HD42011-01/HD/NICHD NIH HHS/ -- HD06274/HD/NICHD NIH HHS/ -- T32 HD07305/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2003 May 23;300(5623):1251-6.

    Publication Date: 2003-11-25
    Description: A major challenge of computational protein design is the creation of novel proteins with arbitrarily chosen three-dimensional structures. Here, we used a general computational strategy that iterates between sequence design and structure prediction to design a 93-residue alpha/beta protein called Top7 with a novel sequence and topology. Top7 was found experimentally to be folded and extremely stable, and the x-ray crystal structure of Top7 is similar (root mean square deviation equals 1.2 angstroms) to the design model. The ability to design a new protein fold makes possible the exploration of the large regions of the protein universe not yet observed in nature.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuhlman, Brian -- Dantas, Gautam -- Ireton, Gregory C -- Varani, Gabriele -- Stoddard, Barry L -- Baker, David -- New York, N.Y. -- Science. 2003 Nov 21;302(5649):1364-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14631033" target="_blank"〉PubMed〈/a〉

    Kin selection in cooperative alliances of carrion crows (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-06-21
    Description: In most cooperative vertebrates, delayed natal dispersal is the mechanism that leads to the formation of kin societies. Under this condition, the possibility that kin-based cooperative breeding is an unselected consequence of dispersal patterns can never be ruled out because helpers can only help their relatives. Here we show that a population of carrion crows (Corvus corone corone) fully fits the central prediction of kin selection theory that cooperative breeding should arise among relatives. On their territory, resident breeders are aided not only by nonbreeding retained offspring but also by immigrants (mainly males), with whom they share matings. Philopatry cannot account, however, for the high degree of genetic relatedness found between breeders and immigrants of the same sex that cooperate at a nest, indicating that crows actively choose to breed cooperatively with their relatives.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baglione, Vittorio -- Canestrari, Daniela -- Marcos, Jose M -- Ekman, Jan -- New York, N.Y. -- Science. 2003 Jun 20;300(5627):1947-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Population Biology/Evolutionary Biology Centre, Uppsala University, Norbyvagen 18D, SE-752 36, Uppsala, Sweden. vittorio.baglione@ebc.uu.se〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12817149" target="_blank"〉PubMed〈/a〉

    Discrete coding of reward probability and uncertainty by dopamine neurons (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-03-22
    Description: Uncertainty is critical in the measure of information and in assessing the accuracy of predictions. It is determined by probability P, being maximal at P = 0.5 and decreasing at higher and lower probabilities. Using distinct stimuli to indicate the probability of reward, we found that the phasic activation of dopamine neurons varied monotonically across the full range of probabilities, supporting past claims that this response codes the discrepancy between predicted and actual reward. In contrast, a previously unobserved response covaried with uncertainty and consisted of a gradual increase in activity until the potential time of reward. The coding of uncertainty suggests a possible role for dopamine signals in attention-based learning and risk-taking behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fiorillo, Christopher D -- Tobler, Philippe N -- Schultz, Wolfram -- 095495/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2003 Mar 21;299(5614):1898-902.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Physiology, University of Fribourg, CH-1700 Fribourg, Switzerland. cdf28@cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12649484" target="_blank"〉PubMed〈/a〉

    Conserved role of nanos proteins in germ cell development (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-08-30
    Description: In Drosophila, maternally supplied Nanos functions in the migration of primordial germ cells (PGCs) into the gonad; in mice, zygotic genes are involved instead. We report the cloning and the functional analyses of nanos2 and nanos3 in mice. These genes are differentially expressed in mouse PGCs. nanos2 is predominantly expressed in male germ cells, and the elimination of this gene results in a complete loss of spermatogonia. However, nanos3 is found in migrating PGCs, and the elimination of this factor results in the complete loss of germ cells in both sexes. Hence, although mice and flies differ in their mechanisms for germ cell specification, there seems to be conserved function for nanos proteins among invertebrates and vertebrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsuda, Masayuki -- Sasaoka, Yumiko -- Kiso, Makoto -- Abe, Kuniya -- Haraguchi, Seiki -- Kobayashi, Satoru -- Saga, Yumiko -- New York, N.Y. -- Science. 2003 Aug 29;301(5637):1239-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Mammalian Development, National Institute of Genetics, SOKENDAI, Yata 1111, Mishima, Shizuoka 411-8540, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12947200" target="_blank"〉PubMed〈/a〉

    Control of effector CD8+ T cell function by the transcription factor Eomesodermin (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-11-08
    Description: Activated CD8+ T cells play a critical role in host defense against viruses, intracellular microbes, and tumors. It is not clear if a key regulatory transcription factor unites the effector functions of CD8+ T cells. We now show that Eomesodermin (Eomes), a paralogue of T-bet, is induced in effector CD8+ T cells in vitro and in vivo. Ectopic expression of Eomes was sufficient to invoke attributes of effector CD8+ T cells, including interferon-gamma (IFN-gamma), perforin, and granzyme B. Loss-of-function analysis suggests Eomes may also be necessary for full effector differentiation of CD8+ T cells. We suggest that Eomesodermin is likely to complement the actions of T-bet and act as a key regulatory gene in the development of cell-mediated immunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pearce, Erika L -- Mullen, Alan C -- Martins, Gislaine A -- Krawczyk, Connie M -- Hutchins, Anne S -- Zediak, Valerie P -- Banica, Monica -- DiCioccio, Catherine B -- Gross, Darrick A -- Mao, Chai-An -- Shen, Hao -- Cereb, Nezih -- Yang, Soo Y -- Lindsten, Tullia -- Rossant, Janet -- Hunter, Christopher A -- Reiner, Steven L -- AI-042370/AI/NIAID NIH HHS/ -- GM-07229/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Nov 7;302(5647):1041-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Abramson Family Cancer Research Institute, and Department of Medicine, University of Pennsylvania, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14605368" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-12-20
    Description: The Caenorhabditis elegans excretory canal is composed of a single elongated and branched cell that is tunneled by an inner lumen of apical character. Loss of the exc-4 gene causes a cystic enlargement of this intracellular tube. exc-4 encodes a member of the chloride intracellular channel (CLIC) family of proteins. EXC-4 protein localizes to various tubular membranes in distinct cell types, including the lumenal membrane of the excretory tubes. A conserved 55-amino acid domain enables EXC-4 translocation from the cytosol to the lumenal membrane. The tubular architecture of this membrane requires EXC-4 for both its formation and maintenance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berry, Katherine L -- Bulow, Hannes E -- Hall, David H -- Hobert, Oliver -- New York, N.Y. -- Science. 2003 Dec 19;302(5653):2134-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biophysics, Center for Neurobiology and Behavior, Columbia University, College of Physicians and Surgeons, New York, NY 10032, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14684823" target="_blank"〉PubMed〈/a〉
