    Description: The detection of single-nucleotide polymorphisms in pathogenic microorganisms has normally been carried out by trial and error. Here we show that DNA hybridization with high-density oligonucleotide arrays provides rapid and convenient detection of single-nucleotide polymorphisms in Plasmodium falciparum, despite its exceptionally high adenine-thymine (AT) content (82%). A disproportionate number of polymorphisms are found in genes encoding proteins associated with the cell membrane. These genes are targets for only 22% of the oligonucleotide probes but account for 69% of the polymorphisms. Genetic variation is also enriched in subtelomeric regions, which account for 22% of the chromosome but 76% of the polymorphisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Volkman, Sarah K -- Hartl, Daniel L -- Wirth, Dyann F -- Nielsen, Kaare M -- Choi, Mehee -- Batalov, Serge -- Zhou, Yingyao -- Plouffe, David -- Le Roch, Karine G -- Abagyan, Ruben -- Winzeler, Elizabeth A -- GM61351/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2002 Oct 4;298(5591):216-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology and Infectious Diseases, Harvard School of Public Health, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12364807" target="_blank"〉PubMed〈/a〉

    Description: Molecular genetic studies of Drosophila melanogaster have led to profound advances in understanding the regulation of development. Here we report gene expression patterns for nearly one-third of all Drosophila genes during a complete time course of development. Mutations that eliminate eye or germline tissue were used to further analyze tissue-specific gene expression programs. These studies define major characteristics of the transcriptional programs that underlie the life cycle, compare development in males and females, and show that large-scale gene expression data collected from whole animals can be used to identify genes expressed in particular tissues and organs or genes involved in specific biological and biochemical processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arbeitman, Michelle N -- Furlong, Eileen E M -- Imam, Farhad -- Johnson, Eric -- Null, Brian H -- Baker, Bruce S -- Krasnow, Mark A -- Scott, Matthew P -- Davis, Ronald W -- White, Kevin P -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2002 Sep 27;297(5590):2270-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Stanford University, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12351791" target="_blank"〉PubMed〈/a〉

    Description: Higher order chromatin structure presents a barrier to the recognition and repair of DNA damage. Double-strand breaks (DSBs) induce histone H2AX phosphorylation, which is associated with the recruitment of repair factors to damaged DNA. To help clarify the physiological role of H2AX, we targeted H2AX in mice. Although H2AX is not essential for irradiation-induced cell-cycle checkpoints, H2AX-/- mice were radiation sensitive, growth retarded, and immune deficient, and mutant males were infertile. These pleiotropic phenotypes were associated with chromosomal instability, repair defects, and impaired recruitment of Nbs1, 53bp1, and Brca1, but not Rad51, to irradiation-induced foci. Thus, H2AX is critical for facilitating the assembly of specific DNA-repair complexes on damaged DNA.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4721576/" 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/PMC4721576/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Celeste, Arkady -- Petersen, Simone -- Romanienko, Peter J -- Fernandez-Capetillo, Oscar -- Chen, Hua Tang -- Sedelnikova, Olga A -- Reina-San-Martin, Bernardo -- Coppola, Vincenzo -- Meffre, Eric -- Difilippantonio, Michael J -- Redon, Christophe -- Pilch, Duane R -- Olaru, Alexandru -- Eckhaus, Michael -- Camerini-Otero, R Daniel -- Tessarollo, Lino -- Livak, Ferenc -- Manova, Katia -- Bonner, William M -- Nussenzweig, Michel C -- Nussenzweig, Andre -- Z99 CA999999/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2002 May 3;296(5569):922-7.

    Description: Positive-strand RNA viruses such as poliovirus replicate their genomes on intracellular membranes of their eukaryotic hosts. Electron microscopy has revealed that purified poliovirus RNA-dependent RNA polymerase forms planar and tubular oligomeric arrays. The structural integrity of these arrays correlates with cooperative RNA binding and RNA elongation and is sensitive to mutations that disrupt intermolecular contacts predicted by the polymerase structure. Membranous vesicles isolated from poliovirus-infected cells contain structures consistent with the presence of two-dimensional polymerase arrays on their surfaces during infection. Therefore, host cytoplasmic membranes may function as physical foundations for two-dimensional polymerase arrays, conferring the advantages of surface catalysis to viral RNA replication.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lyle, John M -- Bullitt, Esther -- Bienz, Kurt -- Kirkegaard, Karla -- AI-42119/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2002 Jun 21;296(5576):2218-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, 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/12077417" target="_blank"〉PubMed〈/a〉

    Description: Full-length poliovirus complementary DNA (cDNA) was synthesized by assembling oligonucleotides of plus and minus strand polarity. The synthetic poliovirus cDNA was transcribed by RNA polymerase into viral RNA, which translated and replicated in a cell-free extract, resulting in the de novo synthesis of infectious poliovirus. Experiments in tissue culture using neutralizing antibodies and CD155 receptor-specific antibodies and neurovirulence tests in CD155 transgenic mice confirmed that the synthetic virus had biochemical and pathogenic characteristics of poliovirus. Our results show that it is possible to synthesize an infectious agent by in vitro chemical-biochemical means solely by following instructions from a written sequence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cello, Jeronimo -- Paul, Aniko V -- Wimmer, Eckard -- New York, N.Y. -- Science. 2002 Aug 9;297(5583):1016-8.

    Description: There is a relation between stress and alcohol drinking. We show that the corticotropin-releasing hormone (CRH) system that mediates endocrine and behavioral responses to stress plays a role in the control of long-term alcohol drinking. In mice lacking a functional CRH1 receptor, stress leads to enhanced and progressively increasing alcohol intake. The effect of repeated stress on alcohol drinking behavior appeared with a delay and persisted throughout life. It was associated with an up-regulation of the N-methyl-d-aspartate receptor subunit NR2B. Alterations in the CRH1 receptor gene and adaptional changes in NR2B subunits may constitute a genetic risk factor for stress-induced alcohol drinking and alcoholism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sillaber, Inge -- Rammes, Gerhard -- Zimmermann, Stephan -- Mahal, Beatrice -- Zieglgansberger, Walter -- Wurst, Wolfgang -- Holsboer, Florian -- Spanagel, Rainer -- New York, N.Y. -- Science. 2002 May 3;296(5569):931-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute of Psychiatry, Kraepelinstrasse 2-10, 80804 Munich, Germany. sillaber@mpipsykl.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11988580" target="_blank"〉PubMed〈/a〉

    Description: The recently released human genome sequences provide us with reference data to conduct comparative genomic research on primates, which will be important to understand what genetic information makes us human. Here we present a first-generation human-chimpanzee comparative genome map and its initial analysis. The map was constructed through paired alignment of 77,461 chimpanzee bacterial artificial chromosome end sequences with publicly available human genome sequences. We detected candidate positions, including two clusters on human chromosome 21 that suggest large, nonrandom regions of difference between the two genomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fujiyama, Asao -- Watanabe, Hidemi -- Toyoda, Atsushi -- Taylor, Todd D -- Itoh, Takehiko -- Tsai, Shih-Feng -- Park, Hong-Seog -- Yaspo, Marie-Laure -- Lehrach, Hans -- Chen, Zhu -- Fu, Gang -- Saitou, Naruya -- Osoegawa, Kazutoyo -- de Jong, Pieter J -- Suto, Yumiko -- Hattori, Masahira -- Sakaki, Yoshiyuki -- New York, N.Y. -- Science. 2002 Jan 4;295(5552):131-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉RIKEN Genomic Sciences Center, 1-7-22 Suehiro-cho, Tsurumi-ku, Yokohama, Kanagawa 230-0045, Japan. afujiyam@gsc.riken.go.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11778049" target="_blank"〉PubMed〈/a〉

    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〉

    Description: Double-stranded RNA-mediated gene interference (RNAi) in Caenorhabditis elegans systemically inhibits gene expression throughout the organism. To investigate how gene-specific silencing information is transmitted between cells, we constructed a strain that permits visualization of systemic RNAi. We used this strain to identify systemic RNA interference-deficient (sid) loci required to spread gene-silencing information between tissues but not to initiate or maintain an RNAi response. One of these loci, sid-1, encodes a conserved protein with predicted transmembrane domains. SID-1 is expressed in cells sensitive to RNAi, is localized to the cell periphery, and is required cell-autonomously for systemic RNAi.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Winston, William M -- Molodowitch, Christina -- Hunter, Craig P -- New York, N.Y. -- Science. 2002 Mar 29;295(5564):2456-9.

    Description: Breast cancer manifests itself in the mammary epithelium, yet there is a growing recognition that mammary stromal cells also play an important role in tumorigenesis. During its developmental cycle, the mammary gland displays many of the properties associated with breast cancer, and many of the stromal factors necessary for mammary development also promote or protect against breast cancer. Here we review our present knowledge of the specific factors and cell types that contribute to epithelial-stromal crosstalk during mammary development. To find cures for diseases like breast cancer that rely on epithelial-stromal crosstalk, we must understand how these different cell types communicate with each other.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2788989/" 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/PMC2788989/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wiseman, Bryony S -- Werb, Zena -- CA57621/CA/NCI NIH HHS/ -- R01 CA057621/CA/NCI NIH HHS/ -- R01 CA057621-07/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2002 May 10;296(5570):1046-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy, University of California, 513 Parnassus Avenue, San Francisco, CA 94143, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12004111" target="_blank"〉PubMed〈/a〉

    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.

    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〉

    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.

    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〉

    Description: The protein-protein interaction between leukocyte functional antigen-1 (LFA-1) and intercellular adhesion molecule-1 (ICAM-1) is critical to lymphocyte and immune system function. Here, we report on the transfer of the contiguous, nonlinear epitope of ICAM-1, responsible for its association with LFA-1, to a small-molecule framework. These LFA-1 antagonists bound LFA-1, blocked binding of ICAM-1, and inhibited a mixed lymphocyte reaction (MLR) with potency significantly greater than that of cyclosporine A. Furthermore, in comparison to an antibody to LFA-1, they exhibited significant anti-inflammatory effects in vivo. These results demonstrate the utility of small-molecule mimics of nonlinear protein epitopes and the protein epitopes themselves as leads in the identification of novel pharmaceutical agents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gadek, T R -- Burdick, D J -- McDowell, R S -- Stanley, M S -- Marsters, J C Jr -- Paris, K J -- Oare, D A -- Reynolds, M E -- Ladner, C -- Zioncheck, K A -- Lee, W P -- Gribling, P -- Dennis, M S -- Skelton, N J -- Tumas, D B -- Clark, K R -- Keating, S M -- Beresini, M H -- Tilley, J W -- Presta, L G -- Bodary, S C -- New York, N.Y. -- Science. 2002 Feb 8;295(5557):1086-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bioorganic Chemistry, Genentech, One DNA Way, South San Francisco, CA 94080, USA. trg@gene.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11834839" target="_blank"〉PubMed〈/a〉

    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〉

    Description: Primary open-angle glaucoma (POAG) affects 33 million individuals worldwide and is a leading cause of blindness. In a study of 54 families with autosomal dominantly inherited adult-onset POAG, we identified the causative gene on chromosome 10p14 and designated it OPTN (for "optineurin"). Sequence alterations in OPTN were found in 16.7% of families with hereditary POAG, including individuals with normal intraocular pressure. The OPTN gene codes for a conserved 66-kilodalton protein of unknown function that has been implicated in the tumor necrosis factor-alpha signaling pathway and that interacts with diverse proteins including Huntingtin, Ras-associated protein RAB8, and transcription factor IIIA. Optineurin is expressed in trabecular meshwork, nonpigmented ciliary epithelium, retina, and brain, and we speculate that it plays a neuroprotective role.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rezaie, Tayebeh -- Child, Anne -- Hitchings, Roger -- Brice, Glen -- Miller, Lauri -- Coca-Prados, Miguel -- Heon, Elise -- Krupin, Theodore -- Ritch, Robert -- Kreutzer, Donald -- Crick, R Pitts -- Sarfarazi, Mansoor -- EY-09947/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2002 Feb 8;295(5557):1077-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Ophthalmic Genetics Laboratory, Surgical Research Center, Department of Surgery, University of Connecticut Health Center, Farmington, CT 06030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11834836" target="_blank"〉PubMed〈/a〉

    Description: The formation and patterning of mesoderm during mammalian gastrulation require the activity of Nodal, a secreted mesoderm-inducing factor of the transforming growth factor-beta (TGF-beta) family. Here we show that the transcriptional corepressor DRAP1 has a very specific role in regulation of Nodal activity during mouse embryogenesis. We find that loss of Drap1 leads to severe gastrulation defects that are consistent with increased expression of Nodal and can be partially suppressed by Nodal heterozygosity. Biochemical studies indicate that DRAP1 interacts with and inhibits DNA binding by the winged-helix transcription factor FoxH1 (FAST), a critical component of a positive feedback loop for Nodal activity. We propose that DRAP1 limits the spread of a morphogenetic signal by down-modulating the response to the Nodal autoregulatory loop.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Iratni, Rabah -- Yan, Yu-Ting -- Chen, Canhe -- Ding, Jixiang -- Zhang, Yi -- Price, Sandy M -- Reinberg, Danny -- Shen, Michael M -- New York, N.Y. -- Science. 2002 Dec 6;298(5600):1996-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Biochemistry, Division of Nucleic Acids Enzymology, University of Medicine and Dentistry of New Jersey-Robert Wood Johnson Medical School, Piscataway, NJ 08854, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12471260" target="_blank"〉PubMed〈/a〉

    Description: Little is known of how plant disease resistance (R) proteins recognize pathogens and activate plant defenses. Rcr3 is specifically required for the function of Cf-2, a Lycopersicon pimpinellifolium gene bred into cultivated tomato (Lycopersicon esculentum) for resistance to Cladosporium fulvum. Rcr3 encodes a secreted papain-like cysteine endoprotease. Genetic analysis shows Rcr3 is allelic to the L. pimpinellifolium Ne gene, which suppresses the Cf-2-dependent autonecrosis conditioned by its L. esculentum allele, ne (necrosis). Rcr3 alleles from these two species encode proteins that differ by only seven amino acids. Possible roles of Rcr3 in Cf-2-dependent defense and autonecrosis are discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kruger, Julia -- Thomas, Colwyn M -- Golstein, Catherine -- Dixon, Mark S -- Smoker, Matthew -- Tang, Saijun -- Mulder, Lonneke -- Jones, Jonathan D G -- New York, N.Y. -- Science. 2002 Apr 26;296(5568):744-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Sainsbury Laboratory, John Innes Centre, Norwich NR4 7UH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11976458" target="_blank"〉PubMed〈/a〉

    Description: The conserved Sir2 family of proteins has protein deacetylase activity that is dependent on NAD (the oxidized form of nicotinamide adenine dinucleotide). Although histones are one likely target for the enzymatic activity of eukaryotic Sir2 proteins, little is known about the substrates and roles of prokaryotic Sir2 homologs. We reveal that an archaeal Sir2 homolog interacts specifically with the major archaeal chromatin protein, Alba, and that Alba exists in acetylated and nonacetylated forms. Furthermore, we show that Sir2 can deacetylate Alba and mediate transcriptional repression in a reconstituted in vitro transcription system. These data provide a paradigm for how Sir2 family proteins influence transcription and suggest that modulation of chromatin structure by acetylation arose before the divergence of the archaeal and eukaryotic lineages.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bell, Stephen D -- Botting, Catherine H -- Wardleworth, Benjamin N -- Jackson, Stephen P -- White, Malcolm F -- New York, N.Y. -- Science. 2002 Apr 5;296(5565):148-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council (MRC) Cancer Cell Unit, The Hutchison/MRC Research Centre, Hills Road, Cambridge, CB2 2QH, UK. sdb@mole.bio.cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11935028" target="_blank"〉PubMed〈/a〉

    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.

    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〉

    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〉

    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〉

    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.

    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〉

    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.

    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〉

    Description: Phytochromes are a family of photoreceptors used by green plants to entrain their development to the light environment. The distribution of these chromoproteins has been expanded beyond photoautotrophs with the discovery of phytochrome-like proteins in the nonphotosynthetic eubacteria Deinococcus radiodurans and Pseudomonas aeruginosa. Like plant phytochromes, the D. radiodurans receptor covalently binds linear tetrapyrroles autocatalytically to generate a photochromic holoprotein. However, the attachment site is distinct, using a histidine to potentially form a Schiff base linkage. Sequence homology and mutational analysis suggest that D. radiodurans bacteriophytochrome functions as a light-regulated histidine kinase, which helps protect the bacterium from visible light.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, S J -- Vener, A V -- Vierstra, R D -- New York, N.Y. -- Science. 1999 Dec 24;286(5449):2517-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetics, Cellular and Molecular Biology Program and Department of Horticulture, University of Wisconsin-Madison, 1575 Linden Drive, Madison, WI 53706, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10617469" target="_blank"〉PubMed〈/a〉

    Description: Mutation at the mouse progressive ankylosis (ank) locus causes a generalized, progressive form of arthritis accompanied by mineral deposition, formation of bony outgrowths, and joint destruction. Here, we show that the ank locus encodes a multipass transmembrane protein (ANK) that is expressed in joints and other tissues and controls pyrophosphate levels in cultured cells. A highly conserved gene is present in humans and other vertebrates. These results identify ANK-mediated control of pyrophosphate levels as a possible mechanism regulating tissue calcification and susceptibility to arthritis in higher animals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ho, A M -- Johnson, M D -- Kingsley, D M -- 5T32GM07365/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Jul 14;289(5477):265-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental Biology and Howard Hughes Medical Institute, Beckman Center B300, Stanford University School of Medicine, Stanford, CA 94305-5327, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10894769" target="_blank"〉PubMed〈/a〉

    Description: Most types of antibiotic resistance impose a biological cost on bacterial fitness. These costs can be compensated, usually without loss of resistance, by second-site mutations during the evolution of the resistant bacteria in an experimental host or in a laboratory medium. Different fitness-compensating mutations were selected depending on whether the bacteria evolved through serial passage in mice or in a laboratory medium. This difference in mutation spectra was caused by either a growth condition-specific formation or selection of the compensated mutants. These results suggest that bacterial evolution to reduce the costs of antibiotic resistance can take different trajectories within and outside a host.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bjorkman, J -- Nagaev, I -- Berg, O G -- Hughes, D -- Andersson, D I -- New York, N.Y. -- Science. 2000 Feb 25;287(5457):1479-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bacteriology, Swedish Institute for Infectious Disease Control, S-171 82 Solna, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10688795" target="_blank"〉PubMed〈/a〉

    Description: Allergic asthma is caused by the aberrant expansion in the lung of T helper cells that produce type 2 (TH2) cytokines and is characterized by infiltration of eosinophils and bronchial hyperreactivity. This disease is often triggered by mast cells activated by immunoglobulin E (IgE)-mediated allergic challenge. Activated mast cells release various chemical mediators, including prostaglandin D2 (PGD2), whose role in allergic asthma has now been investigated by the generation of mice deficient in the PGD receptor (DP). Sensitization and aerosol challenge of the homozygous mutant (DP-/-) mice with ovalbumin (OVA) induced increases in the serum concentration of IgE similar to those in wild-type mice subjected to this model of asthma. However, the concentrations of TH2 cytokines and the extent of lymphocyte accumulation in the lung of OVA-challenged DP-/- mice were greatly reduced compared with those in wild-type animals. Moreover, DP-/- mice showed only marginal infiltration of eosinophils and failed to develop airway hyperreactivity. Thus, PGD2 functions as a mast cell-derived mediator to trigger asthmatic responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsuoka, T -- Hirata, M -- Tanaka, H -- Takahashi, Y -- Murata, T -- Kabashima, K -- Sugimoto, Y -- Kobayashi, T -- Ushikubi, F -- Aze, Y -- Eguchi, N -- Urade, Y -- Yoshida, N -- Kimura, K -- Mizoguchi, A -- Honda, Y -- Nagai, H -- Narumiya, S -- New York, N.Y. -- Science. 2000 Mar 17;287(5460):2013-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Kyoto University Faculty of Medicine, Kyoto 606-8501, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10720327" target="_blank"〉PubMed〈/a〉

    Description: Activation of the transcription factor nuclear factor (NF)-kappaB by proinflammatory stimuli leads to increased expression of genes involved in inflammation. Activation of NF-kappaB requires the activity of an inhibitor of kappaB (IkappaB)-kinase (IKK) complex containing two kinases (IKKalpha and IKKbeta) and the regulatory protein NEMO (NF-kappaB essential modifier). An amino-terminal alpha-helical region of NEMO associated with a carboxyl-terminal segment of IKKalpha and IKKbeta that we term the NEMO-binding domain (NBD). A cell-permeable NBD peptide blocked association of NEMO with the IKK complex and inhibited cytokine-induced NF-kappaB activation and NF-kappaB-dependent gene expression. The peptide also ameliorated inflammatory responses in two experimental mouse models of acute inflammation. The NBD provides a target for the development of drugs that would block proinflammatory activation of the IKK complex without inhibiting basal NF-kappaB activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉May, M J -- D'Acquisto, F -- Madge, L A -- Glockner, J -- Pober, J S -- Ghosh, S -- AI 33443/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2000 Sep 1;289(5484):1550-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Immunobiology and Department of Molecular Biophysics and Biochemistry, Howard Hughes Medical Institute, Yale University School of Medicine, New Haven, CT 06510, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10968790" target="_blank"〉PubMed〈/a〉

    Description: The large chlorella virus PBCV-1, which contains double-stranded DNA (dsDNA), encodes a 94-codon open reading frame (ORF) that contains a motif resembling the signature sequence of the pore domain of potassium channel proteins. Phylogenetic analyses of the encoded protein, Kcv, indicate a previously unidentified type of potassium channel. The messenger RNA encoded by the ORF leads to functional expression of a potassium-selective conductance in Xenopus laevis oocytes. The channel blockers amantadine and barium, but not cesium, inhibit this conductance, in addition to virus plaque formation. Thus, PBCV-1 encodes the first known viral protein that functions as a potassium-selective channel and is essential in the virus life cycle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Plugge, B -- Gazzarrini, S -- Nelson, M -- Cerana, R -- Van Etten, J L -- Derst, C -- DiFrancesco, D -- Moroni, A -- Thiel, G -- 971/Telethon/Italy -- GM32441/GM/NIGMS NIH HHS/ -- GM41333/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Mar 3;287(5458):1641-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Albrecht-von-Haller-Institut fur Pflanzenwissenschaften, Universitat Gottingen, 37073 Gottingen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10698737" target="_blank"〉PubMed〈/a〉

    Description: The maternal determinant Bicoid (Bcd) represents the paradigm of a morphogen that provides positional information for pattern formation. However, as bicoid seems to be a recently acquired gene in flies, the question was raised as to how embryonic patterning is achieved in organisms with more ancestral modes of development. Because the phylogenetically conserved Hunchback (Hb) protein had previously been shown to act as a morphogen in abdominal patterning, we asked which functions of Bcd could be performed by Hb. By reestablishing a proposed ancient regulatory circuitry in which maternal Hb controls zygotic hunchback expression, we show that Hb is able to form thoracic segments in the absence of Bcd.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wimmer, E A -- Carleton, A -- Harjes, P -- Turner, T -- Desplan, C -- New York, N.Y. -- Science. 2000 Mar 31;287(5462):2476-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lehrstuhl Genetik, Universitat Bayreuth, 95447 Bayreuth, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10741965" target="_blank"〉PubMed〈/a〉

On St. Lucia, an island in the West Indies, female caribs sport bills a third longer and twice as curved as those of their male counterparts--one of the most extreme bill differences between the sexes in any hummingbird species. In the paper, the researchers link these "whoppingly dimorphic bills" to the specific flowers the male and female caribs frequent.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brown, K -- New York, N.Y. -- Science. 2000 Jul 21;289(5478):369-71.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10939937" target="_blank"〉PubMed〈/a〉

    Description: Experts in the young field of violence epidemiology blame guns and crack cocaine for America's deadly crime surge in the early 1990s. Explaining the subsequent decline in violent crime rates has been more difficult, however. Some of the factors that seem to have helped squelch crime could be temporary, such as low unemployment rates. But others, including a growing intolerance for violence as a means of settling interpersonal disputes, seem to have become cultural norms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Helmuth, L -- New York, N.Y. -- Science. 2000 Jul 28;289(5479):582-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10939973" target="_blank"〉PubMed〈/a〉

    Description: To determine the ability of antibodies to provide protection from Ebola viruses, monoclonal antibodies (mAbs) to the Ebola glycoprotein were generated and evaluated for efficacy. We identified several protective mAbs directed toward five unique epitopes on Ebola glycoprotein. One of the epitopes is conserved among all Ebola viruses that are known to be pathogenic for humans. Some protective mAbs were also effective therapeutically when administered to mice 2 days after exposure to lethal Ebola virus. The identification of protective mAbs has important implications for developing vaccines and therapies for Ebola virus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, J A -- Hevey, M -- Bakken, R -- Guest, S -- Bray, M -- Schmaljohn, A L -- Hart, M K -- New York, N.Y. -- Science. 2000 Mar 3;287(5458):1664-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Virology Division, U.S. Army Medical Research Institute of Infectious Diseases, 1425 Porter Street, Fort Detrick, Frederick, MD 21702-5011, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10698744" target="_blank"〉PubMed〈/a〉

    Description: A fundamental question in aging research is whether humans and other species possess an immutable life-span limit. We examined the maximum age at death in Sweden, which rose from about 101 years during the 1860s to about 108 years during the 1990s. The pace of increase was 0.44 years per decade before 1969 but accelerated to 1. 11 years per decade after that date. More than 70 percent of the rise in the maximum age at death from 1861 to 1999 is attributable to reductions in death rates above age 70. The rest are due to increased numbers of survivors to old age (both larger birth cohorts and increased survivorship from infancy to age 70). The more rapid rise in the maximum age since 1969 is due to the faster pace of old-age mortality decline during recent decades.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilmoth, J R -- Deegan, L J -- Lundstrom, H -- Horiuchi, S -- K02-AG00778/AG/NIA NIH HHS/ -- R01-AG11552/AG/NIA NIH HHS/ -- R01-AG14698/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2000 Sep 29;289(5488):2366-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Demography, University of California, Berkeley, CA 94720-2120, USA. jrw@demog.berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11009426" target="_blank"〉PubMed〈/a〉

    Description: Chronic blockade of dopamine D2 receptors, a common mechanism of action for antipsychotic drugs, down-regulates D1 receptors in the prefrontal cortex and, as shown here, produces severe impairments in working memory. These deficits were reversed in monkeys by short-term coadministration of a D1 agonist, ABT 431, and this improvement was sustained for more than a year after cessation of D1 treatment. These findings indicate that pharmacological modulation of the D1 signaling pathway can produce long-lasting changes in functional circuits underlying working memory. Resetting this pathway by brief exposure to the agonist may provide a valuable strategy for therapeutic intervention in schizophrenia and other dopamine dysfunctional states.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Castner, S A -- Williams, G V -- Goldman-Rakic, P S -- P01DA10160/DA/NIDA NIH HHS/ -- P50MH44866/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2000 Mar 17;287(5460):2020-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Neurobiology, Yale University School of Medicine, 333 Cedar Street, New Haven, CT 06510, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10720329" target="_blank"〉PubMed〈/a〉

    Description: Repetition priming has been characterized neurophysiologically as a decreased response following stimulus repetition. The present study used event-related functional magnetic resonance imaging to investigate whether this repetition-related response is sensitive to stimulus familiarity. A right fusiform region exhibited an attenuated response to the repetition of familiar stimuli, both faces and symbols, but exhibited an enhanced response to the repetition of unfamiliar stimuli. Moreover, both repetition effects were modulated by lag between successive presentations. Further experiments replicated the interactions between repetition, familiarity, and lag and demonstrated the persistence of these effects over multiple repetitions. Priming-related responses are therefore not unitary but depend on the presence or absence of preexisting stimulus representations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Henson, R -- Shallice, T -- Dolan, R -- New York, N.Y. -- Science. 2000 Feb 18;287(5456):1269-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Department of Cognitive Neurology, Institute of Neurology, Institute of Cognitive Neuroscience and Department of Psychology, University College London, London WC1E 6BT, UK. r.henson@ucl.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10678834" target="_blank"〉PubMed〈/a〉

    Description: The molecular control of self-renewal and differentiation of stem cells has remained enigmatic. Transgenic loss-of-function and overexpression models now show that the dosage of glial cell line-derived neurotrophic factor (GDNF), produced by Sertoli cells, regulates cell fate decisions of undifferentiated spermatogonial cells that include the stem cells for spermatogenesis. Gene-targeted mice with one GDNF-null allele show depletion of stem cell reserves, whereas mice overexpressing GDNF show accumulation of undifferentiated spermatogonia. They are unable to respond properly to differentiation signals and undergo apoptosis upon retinoic acid treatment. Nonmetastatic testicular tumors are regularly formed in older GDNF-overexpressing mice. Thus, GDNF contributes to paracrine regulation of spermatogonial self-renewal and differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meng, X -- Lindahl, M -- Hyvonen, M E -- Parvinen, M -- de Rooij, D G -- Hess, M W -- Raatikainen-Ahokas, A -- Sainio, K -- Rauvala, H -- Lakso, M -- Pichel, J G -- Westphal, H -- Saarma, M -- Sariola, H -- New York, N.Y. -- Science. 2000 Feb 25;287(5457):1489-93.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Programs of Developmental Biology, Molecular Neurobiology, Electron Microscopy Unit, Institute of Biotechnology, Viikki Biocenter, Finland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10688798" target="_blank"〉PubMed〈/a〉

    Description: The hypothesis that learning occurs through long-term potentiation (LTP)- and long-term depression (LTD)-like mechanisms is widely held but unproven. This hypothesis makes three assumptions: Synapses are modifiable, they modify with learning, and they strengthen through an LTP-like mechanism. We previously established the ability for synaptic modification and a synaptic strengthening with motor skill learning in horizontal connections of the rat motor cortex (MI). Here we investigated whether learning strengthened these connections through LTP. We demonstrated that synapses in the trained MI were near the ceiling of their modification range, compared with the untrained MI, but the range of synaptic modification was not affected by learning. In the trained MI, LTP was markedly reduced and LTD was enhanced. These results are consistent with the use of LTP to strengthen synapses during learning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rioult-Pedotti, M S -- Friedman, D -- Donoghue, J P -- NS27164/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2000 Oct 20;290(5491):533-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience, Brown University, Providence, RI 02912, USA. mengia_rioult@brown.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11039938" target="_blank"〉PubMed〈/a〉

    Description: Stromal cells are thought to generate specific regulatory microenviroments or "niches" that control stem cell behavior. Characterizing stem cell niches in vivo remains an important goal that has been difficult to achieve. The individual ovarioles of the Drosophila ovary each contain about two germ line stem cells that maintain oocyte production. Here we show that anterior ovariolar somatic cells comprising three cell types act as a germ line stem cell niche. Germ line stem cells lost by normal or induced differentiation are efficiently replaced, and the ability to repopulate the niche increases the functional lifetime of ovarioles in vivo. Our studies implicate one of the somatic cell types, the cap cells, as a key niche component.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xie, T -- Spradling, A C -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2000 Oct 13;290(5490):328-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Embryology, Howard Hughes Medical Institute, Carnegie Institution of Washington, 115 West University Parkway, Baltimore, MD 21210, USA. tgx@stowers-institute.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11030649" target="_blank"〉PubMed〈/a〉

    Description: Ectodysplasin, a member of the tumor necrosis factor family, is encoded by the anhidrotic ectodermal dysplasia (EDA) gene. Mutations in EDA give rise to a clinical syndrome characterized by loss of hair, sweat glands, and teeth. EDA-A1 and EDA-A2 are two isoforms of ectodysplasin that differ only by an insertion of two amino acids. This insertion functions to determine receptor binding specificity, such that EDA-A1 binds only the receptor EDAR, whereas EDA-A2 binds only the related, but distinct, X-linked ectodysplasin-A2 receptor (XEDAR). In situ binding and organ culture studies indicate that EDA-A1 and EDA-A2 are differentially expressed and play a role in epidermal morphogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yan, M -- Wang, L C -- Hymowitz, S G -- Schilbach, S -- Lee, J -- Goddard, A -- de Vos, A M -- Gao, W Q -- Dixit, V M -- New York, N.Y. -- Science. 2000 Oct 20;290(5491):523-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Oncology, Genentech, 1 DNA Way, South San Francisco, CA 94080, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11039935" target="_blank"〉PubMed〈/a〉

    Description: The 2,272,351-base pair genome of Neisseria meningitidis strain MC58 (serogroup B), a causative agent of meningitis and septicemia, contains 2158 predicted coding regions, 1158 (53.7%) of which were assigned a biological role. Three major islands of horizontal DNA transfer were identified; two of these contain genes encoding proteins involved in pathogenicity, and the third island contains coding sequences only for hypothetical proteins. Insights into the commensal and virulence behavior of N. meningitidis can be gleaned from the genome, in which sequences for structural proteins of the pilus are clustered and several coding regions unique to serogroup B capsular polysaccharide synthesis can be identified. Finally, N. meningitidis contains more genes that undergo phase variation than any pathogen studied to date, a mechanism that controls their expression and contributes to the evasion of the host immune system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tettelin, H -- Saunders, N J -- Heidelberg, J -- Jeffries, A C -- Nelson, K E -- Eisen, J A -- Ketchum, K A -- Hood, D W -- Peden, J F -- Dodson, R J -- Nelson, W C -- Gwinn, M L -- DeBoy, R -- Peterson, J D -- Hickey, E K -- Haft, D H -- Salzberg, S L -- White, O -- Fleischmann, R D -- Dougherty, B A -- Mason, T -- Ciecko, A -- Parksey, D S -- Blair, E -- Cittone, H -- Clark, E B -- Cotton, M D -- Utterback, T R -- Khouri, H -- Qin, H -- Vamathevan, J -- Gill, J -- Scarlato, V -- Masignani, V -- Pizza, M -- Grandi, G -- Sun, L -- Smith, H O -- Fraser, C M -- Moxon, E R -- Rappuoli, R -- Venter, J C -- New York, N.Y. -- Science. 2000 Mar 10;287(5459):1809-15.〈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/10710307" target="_blank"〉PubMed〈/a〉

    Description: Construction of four dams on the lower Snake River (in northwestern United States) between 1961 and 1975 altered salmon spawning habitat, elevated smolt and adult migration mortality, and contributed to severe declines of Snake River salmon populations. By applying a matrix model to long-term population data, we found that (i) dam passage improvements have dramatically mitigated direct mortality associated with dams; (ii) even if main stem survival were elevated to 100%, Snake River spring/summer chinook salmon (Oncorhynchus tshawytscha) would probably continue to decline toward extinction; and (iii) modest reductions in first-year mortality or estuarine mortality would reverse current population declines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kareiva, P -- Marvier, M -- McClure, M -- New York, N.Y. -- Science. 2000 Nov 3;290(5493):977-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Marine Fisheries Service, Northwest Fisheries Science Center, 2725 Montlake Boulevard East, Seattle, WA 98112, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11062128" target="_blank"〉PubMed〈/a〉

    Description: A major modification to the sterile insect technique is described, in which transgenic insects homozygous for a dominant, repressible, female-specific lethal gene system are used. We demonstrate two methods that give the required genetic characteristics in an otherwise wild-type genetic background. The first system uses a sex-specific promoter or enhancer to drive the expression of a repressible transcription factor, which in turn controls the expression of a toxic gene product. The second system uses non-sex-specific expression of the repressible transcription factor to regulate a selectively lethal gene product. Both methods work efficiently in Drosophila melanogaster, and we expect these principles to be widely applicable to more economically important organisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thomas, D D -- Donnelly, C A -- Wood, R J -- Alphey, L S -- New York, N.Y. -- Science. 2000 Mar 31;287(5462):2474-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, Wellcome Trust Centre for the Epidemiology of Infectious Disease, Department of Zoology, University of Oxford, South Parks Road, Oxford OX1 3PS, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10741964" target="_blank"〉PubMed〈/a〉

    Description: Theories of the regulation of cognition suggest a system with two necessary components: one to implement control and another to monitor performance and signal when adjustments in control are needed. Event-related functional magnetic resonance imaging and a task-switching version of the Stroop task were used to examine whether these components of cognitive control have distinct neural bases in the human brain. A double dissociation was found. During task preparation, the left dorsolateral prefrontal cortex (Brodmann's area 9) was more active for color naming than for word reading, consistent with a role in the implementation of control. In contrast, the anterior cingulate cortex (Brodmann's areas 24 and 32) was more active when responding to incongruent stimuli, consistent with a role in performance monitoring.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacDonald, A W 3rd -- Cohen, J D -- Stenger, V A -- Carter, C S -- New York, N.Y. -- Science. 2000 Jun 9;288(5472):1835-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of Pittsburgh, Pittsburgh, PA 15260, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10846167" target="_blank"〉PubMed〈/a〉

    Description: Using the atomic structures of the large ribosomal subunit from Haloarcula marismortui and its complexes with two substrate analogs, we establish that the ribosome is a ribozyme and address the catalytic properties of its all-RNA active site. Both substrate analogs are contacted exclusively by conserved ribosomal RNA (rRNA) residues from domain V of 23S rRNA; there are no protein side-chain atoms closer than about 18 angstroms to the peptide bond being synthesized. The mechanism of peptide bond synthesis appears to resemble the reverse of the acylation step in serine proteases, with the base of A2486 (A2451 in Escherichia coli) playing the same general base role as histidine-57 in chymotrypsin. The unusual pK(a) (where K(a) is the acid dissociation constant) required for A2486 to perform this function may derive in part from its hydrogen bonding to G2482 (G2447 in E. coli), which also interacts with a buried phosphate that could stabilize unusual tautomers of these two bases. The polypeptide exit tunnel is largely formed by RNA but has significant contributions from proteins L4, L22, and L39e, and its exit is encircled by proteins L19, L22, L23, L24, L29, and L31e.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nissen, P -- Hansen, J -- Ban, N -- Moore, P B -- Steitz, T A -- GM22778/GM/NIGMS NIH HHS/ -- GM54216/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Aug 11;289(5481):920-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biophysics and Biochemistry and Department of Chemistry, Yale University, and Howard Hughes Medical Institute, New Haven, CT 06520-8114, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10937990" target="_blank"〉PubMed〈/a〉

    Description: A task force here has been studying cases of variant Creutzfeldt-Jakob disease (vCJD), an incurable malady of the brain and nervous system that has been linked to eating beef or other products from cattle infected with bovine spongiform encephalopathy or "mad cow disease." The team's goal is to find out just how the patients got infected and how many of them there may ultimately be. The number of confirmed or probable vCJD cases in the United Kingdom is still relatively small--a total of 80 as Science went to press--and recent estimates of the number of potential cases are lower than was once feared. Yet the task force's own recent results show that the incidence of vCJD is rising, and researchers remain determined to try to solve the riddles posed by vCJD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Balter, M -- New York, N.Y. -- Science. 2000 Sep 1;289(5484):1452-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10991726" target="_blank"〉PubMed〈/a〉

    Description: Certain genes are only expressed at one allele, a phenomenon called imprinting. Although it is well established that one allele of certain imprinted genes is silenced through methylation, this does not appear to be the case for all imprinted genes. In a thoughtful Perspective, Thorvaldsen and Bartolomei discuss new findings showing that insertion of insulator elements (boundary regions) between the promoter of a gene and its enhancer (a sequence that boosts gene expression) may be another way in which genes are silenced during imprinting.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thorvaldsen, J L -- Bartolomei, M S -- New York, N.Y. -- Science. 2000 Jun 23;288(5474):2145-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Cell and Developmental Biology, University of Pennsylvania School of Medicine, Philadelphia, PA 19104, USA. thorvald@mail.med.upenn.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10896590" target="_blank"〉PubMed〈/a〉

    Description: A Drosophila model for Huntington's and other polyglutamine diseases was used to screen for genetic factors modifying the degeneration caused by expression of polyglutamine in the eye. Among 7000 P-element insertions, several suppressor strains were isolated, two of which led to the discovery of the suppressor genes described here. The predicted product of one, dHDJ1, is homologous to human heat shock protein 40/HDJ1. That of the second, dTPR2, is homologous to the human tetratricopeptide repeat protein 2. Each of these molecules contains a chaperone-related J domain. Their suppression of polyglutamine toxicity was verified in transgenic flies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kazemi-Esfarjani, P -- Benzer, S -- New York, N.Y. -- Science. 2000 Mar 10;287(5459):1837-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, California Institute of Technology, Pasadena, CA 91125, USA. parsa@its.caltech.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10710314" target="_blank"〉PubMed〈/a〉

    Description: The nonclassical major histocompatibility complex (MHC) class I molecule HLA-E inhibits natural killer (NK) cell-mediated lysis by interacting with CD94/NKG2A receptors. Surface expression of HLA-E depends on binding of conserved peptides derived from MHC class I molecules. The same peptide is present in the leader sequence of the human cytomegalovirus (HCMV) glycoprotein UL40 (gpUL40). It is shown that, independently of the transporter associated with antigen processing, gpUL40 can up-regulate expression of HLA-E, which protects targets from NK cell lysis. While classical MHC class I molecules are down-regulated, HLA-E is up-regulated by HCMV. Induction of HLA-E surface expression by gpUL40 may represent an escape route for HCMV.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tomasec, P -- Braud, V M -- Rickards, C -- Powell, M B -- McSharry, B P -- Gadola, S -- Cerundolo, V -- Borysiewicz, L K -- McMichael, A J -- Wilkinson, G W -- New York, N.Y. -- Science. 2000 Feb 11;287(5455):1031.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of Wales College of Medicine, Cardiff CF14 4XN, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10669413" target="_blank"〉PubMed〈/a〉

    Description: Multicellular organisms use the products of highly polymorphic genes to distinguish self from conspecific nonself cells or tissues. These allorecognition polymorphisms may regulate somatic interactions between hosts and pathogens or between competitors (to avoid various forms of parasitism), as well as reproductive interactions between mates or between gametes (to avoid inbreeding). In both cases, rare alleles may be advantageous, but it remains unclear which mechanism maintains the genetic polymorphism for specificity in self/nonself recognition. Contrary to earlier reports, we show that mate selection cannot be a strong force maintaining allorecognition polymorphism in two colonial marine invertebrates. Instead, the regulation of intraspecific competitive interactions appears to promote the evolution of polymorphisms in these species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grosberg, R K -- Hart, M W -- New York, N.Y. -- Science. 2000 Sep 22;289(5487):2111-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Evolution and Ecology and Center for Population Biology, One Shields Drive, University of California, Davis, CA 95616, USA. rkgrosberg@ucdavis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11000110" target="_blank"〉PubMed〈/a〉

    Description: Susceptibility to murine and human insulin-dependent diabetes mellitus correlates strongly with major histocompatibility complex (MHC) class II I-A or HLA-DQ alleles that lack an aspartic acid at position beta57. I-Ag7 lacks this aspartate and is the only class II allele expressed by the nonobese diabetic mouse. The crystal structure of I-Ag7 was determined at 2.6 angstrom resolution as a complex with a high-affinity peptide from the autoantigen glutamic acid decarboxylase (GAD) 65. I-Ag7 has a substantially wider peptide-binding groove around beta57, which accounts for distinct peptide preferences compared with other MHC class II alleles. Loss of Asp(beta57) leads to an oxyanion hole in I-Ag7 that can be filled by peptide carboxyl residues or, perhaps, through interaction with the T cell receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Corper, A L -- Stratmann, T -- Apostolopoulos, V -- Scott, C A -- Garcia, K C -- Kang, A S -- Wilson, I A -- Teyton, L -- CA58896/CA/NCI NIH HHS/ -- DK55037/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2000 Apr 21;288(5465):505-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology and Skaggs Institute for Chemical 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/10775108" target="_blank"〉PubMed〈/a〉

    Description: All cellular organisms use specialized RNA polymerases called "primases" to synthesize RNA primers for the initiation of DNA replication. The high-resolution crystal structure of a primase, comprising the catalytic core of the Escherichia coli DnaG protein, was determined. The core structure contains an active-site architecture that is unrelated to other DNA or RNA polymerase palm folds, but is instead related to the "toprim" fold. On the basis of the structure, it is likely that DnaG binds nucleic acid in a groove clustered with invariant residues and that DnaG is positioned within the replisome to accept single-stranded DNA directly from the replicative helicase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keck, J L -- Roche, D D -- Lynch, A S -- Berger, J M -- New York, N.Y. -- Science. 2000 Mar 31;287(5462):2482-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, University of California, Berkeley, 229 Stanley Hall, no. 3206, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10741967" target="_blank"〉PubMed〈/a〉

    Description: The circadian oscillator of the cyanobacterium Synechococcus elongatus, like those in eukaryotes, is entrained by environmental cues. Inactivation of the gene cikA (circadian input kinase) shortens the circadian period of gene expression rhythms in S. elongatus by approximately 2 hours, changes the phasing of a subset of rhythms, and nearly abolishes resetting of phase by a pulse of darkness. The CikA protein sequence reveals that it is a divergent bacteriophytochrome with characteristic histidine protein kinase motifs and a cryptic response regulator motif. CikA is likely a key component of a pathway that provides environmental input to the circadian oscillator in S. elongatus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmitz, O -- Katayama, M -- Williams, S B -- Kondo, T -- Golden, S S -- GM37040/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Aug 4;289(5480):765-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Texas A&M University, College Station, TX 77843-3258, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10926536" target="_blank"〉PubMed〈/a〉

    Description: The telomerase ribonucleoprotein has a phylogenetically divergent RNA subunit, which contains a short template for telomeric DNA synthesis. To understand how telomerase RNA participates in mechanistic aspects of telomere synthesis, we studied a conserved secondary structure adjacent to the template. Disruption of this structure caused DNA synthesis to proceed beyond the normal template boundary, resulting in altered telomere sequences, telomere shortening, and cellular growth defects. Compensatory mutations restored normal telomerase function. Thus, the RNA structure, rather than its sequence, specifies the template boundary. This study reveals a specific function for an RNA structure in the enzymatic action of telomerase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tzfati, Y -- Fulton, T B -- Roy, J -- Blackburn, E H -- GM26259/GM/NIGMS NIH HHS/ -- T32CA09270/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2000 May 5;288(5467):863-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, University of California, San Francisco, San Francisco, CA 94143-0414, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10797010" target="_blank"〉PubMed〈/a〉

We present a phylogenetic analysis of white blood cell counts in primates to test three hypotheses related to disease risk: increases in risk are expected with group size or population density, exposure to soil-borne pathogens, and mating promiscuity. White blood cell counts were significantly greater in species where females have more mating partners, indicating that the risk of sexually transmitted disease is likely to be a major factor leading to systematic differences in the primate immune system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nunn, C L -- Gittleman, J L -- Antonovics, J -- GM60766-01/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Nov 10;290(5494):1168-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Gilmer Hall, University of Virginia, Charlottesville, VA 22904-4328, USA. charlie.nunn@virginia.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11073457" target="_blank"〉PubMed〈/a〉

    Description: We describe a single RNA sequence that can assume either of two ribozyme folds and catalyze the two respective reactions. The two ribozyme folds share no evolutionary history and are completely different, with no base pairs (and probably no hydrogen bonds) in common. Minor variants of this sequence are highly active for one or the other reaction, and can be accessed from prototype ribozymes through a series of neutral mutations. Thus, in the course of evolution, new RNA folds could arise from preexisting folds, without the need to carry inactive intermediate sequences. This raises the possibility that biological RNAs having no structural or functional similarity might share a common ancestry. Furthermore, functional and structural divergence might, in some cases, precede rather than follow gene duplication.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schultes, E A -- Bartel, D P -- New York, N.Y. -- Science. 2000 Jul 21;289(5478):448-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research and Department of Biology, Massachusetts Institute of Technology, 9 Cambridge Center, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10903205" target="_blank"〉PubMed〈/a〉

    Description: Reciprocal gene activation and restriction during cell type differentiation from a common lineage is a hallmark of mammalian organogenesis. A key question, then, is whether a critical transcriptional activator of cell type-specific gene targets can also restrict expression of the same genes in other cell types. Here, we show that whereas the pituitary-specific POU domain factor Pit-1 activates growth hormone gene expression in one cell type, the somatotrope, it restricts its expression from a second cell type, the lactotrope. This distinction depends on a two-base pair spacing in accommodation of the bipartite POU domains on a conserved growth hormone promoter site. The allosteric effect on Pit-1, in combination with other DNA binding factors, results in the recruitment of a corepressor complex, including nuclear receptor corepressor N-CoR, which, unexpectedly, is required for active long-term repression of the growth hormone gene in lactotropes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scully, K M -- Jacobson, E M -- Jepsen, K -- Lunyak, V -- Viadiu, H -- Carriere, C -- Rose, D W -- Hooshmand, F -- Aggarwal, A K -- Rosenfeld, M G -- R01 DK18477/DK/NIDDK NIH HHS/ -- R01 DK54802/DK/NIDDK NIH HHS/ -- R01 GM49327/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Nov 10;290(5494):1127-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Endocrinology and Metabolism, School of Medicine, University of California, San Diego, La Jolla, CA 92093, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11073444" target="_blank"〉PubMed〈/a〉

    Description: Atomic force microscopy and single-molecule force spectroscopy were combined to image and manipulate purple membrane patches from Halobacterium salinarum. Individual bacteriorhodopsin molecules were first localized and then extracted from the membrane; the remaining vacancies were imaged again. Anchoring forces between 100 and 200 piconewtons for the different helices were found. Upon extraction, the helices were found to unfold. The force spectra revealed the individuality of the unfolding pathways. Helices G and F as well as helices E and D always unfolded pairwise, whereas helices B and C occasionally unfolded one after the other. Experiments with cleaved loops revealed the origin of the individuality: stabilization of helix B by neighboring helices.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Oesterhelt, F -- Oesterhelt, D -- Pfeiffer, M -- Engel, A -- Gaub, H E -- Muller, D J -- New York, N.Y. -- Science. 2000 Apr 7;288(5463):143-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉CeNS and Lehrstuhl fur angewandte Physik, Ludwig Maximilians-Universitat Munchen, Amalienstrasse 54, 80799 Munchen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10753119" target="_blank"〉PubMed〈/a〉

    Description: Pig cloning will have a marked impact on the optimization of meat production and xenotransplantation. To clone pigs from differentiated cells, we microinjected the nuclei of porcine (Sus scrofa) fetal fibroblasts into enucleated oocytes, and development was induced by electroactivation. The transfer of 110 cloned embryos to four surrogate mothers produced an apparently normal female piglet. The clonal provenance of the piglet was indicated by her coat color and confirmed by DNA microsatellite analysis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Onishi, A -- Iwamoto, M -- Akita, T -- Mikawa, S -- Takeda, K -- Awata, T -- Hanada, H -- Perry, A C -- New York, N.Y. -- Science. 2000 Aug 18;289(5482):1188-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Animal Breeding and Genetics, National Institute of Animal Industry, Tsukuba Norin Danchi, Ibaraki-ken 305-0901, Japan. onishi@niai.affrc.go.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10947985" target="_blank"〉PubMed〈/a〉

    Description: The signal recognition particle (SRP), a protein-RNA complex conserved in all three kingdoms of life, recognizes and transports specific proteins to cellular membranes for insertion or secretion. We describe here the 1.8 angstrom crystal structure of the universal core of the SRP, revealing protein recognition of a distorted RNA minor groove. Nucleotide analog interference mapping demonstrates the biological importance of observed interactions, and genetic results show that this core is functional in vivo. The structure explains why the conserved residues in the protein and RNA are required for SRP assembly and defines a signal sequence recognition surface composed of both protein and RNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Batey, R T -- Rambo, R P -- Lucast, L -- Rha, B -- Doudna, J A -- New York, N.Y. -- Science. 2000 Feb 18;287(5456):1232-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biophysics and Biochemistry, Howard Hughes Medical Institute, Yale University, New Haven, CT 06511, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10678824" target="_blank"〉PubMed〈/a〉

    Description: DARPP-32, a dopamine- and adenosine 3',5'-monophosphate (cAMP)-regulated phosphoprotein (32 kilodaltons in size), is an obligate intermediate in progesterone (P)-facilitated sexual receptivity in female rats and mice. The facilitative effect of P on sexual receptivity in female rats was blocked by antisense oligonucleotides to DARPP-32. Homozygous mice carrying a null mutation for the DARPP-32 gene exhibited minimal levels of P-facilitated sexual receptivity when compared to their wild-type littermates. P significantly increased hypothalamic cAMP levels and cAMP-dependent protein kinase activity. These increases were not inhibited by a D1 subclass dopamine receptor antagonist. P also enhanced phosphorylation of DARPP-32 on threonine 34 in the hypothalamus of mice. DARPP-32 activation is thus an obligatory step in progestin receptor regulation of sexual receptivity in rats and mice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mani, S K -- Fienberg, A A -- O'Callaghan, J P -- Snyder, G L -- Allen, P B -- Dash, P K -- Moore, A N -- Mitchell, A J -- Bibb, J -- Greengard, P -- O'Malley, B W -- MH49662/MH/NIMH NIH HHS/ -- MH57442/MH/NIMH NIH HHS/ -- NS 35457/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 2000 Feb 11;287(5455):1053-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Biology, Baylor College of Medicine, Houston, TX 77030, USA. smani@bcm.tmc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10669419" target="_blank"〉PubMed〈/a〉

    Description: Evidence of simian immunodeficiency virus (SIV) infection has been reported for 26 different species of African nonhuman primates. Two of these viruses, SIVcpz from chimpanzees and SIVsm from sooty mangabeys, are the cause of acquired immunodeficiency syndrome (AIDS) in humans. Together, they have been transmitted to humans on at least seven occasions. The implications of human infection by a diverse set of SIVs and of exposure to a plethora of additional human immunodeficiency virus-related viruses are discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hahn, B H -- Shaw, G M -- De Cock, K M -- Sharp, P M -- N01 AI 35338/AI/NIAID NIH HHS/ -- R01 AI 40951/AI/NIAID NIH HHS/ -- R01 AI 44596/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2000 Jan 28;287(5453):607-14.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Howard Hughes Medical Institute, University of Alabama at Birmingham, Birmingham, AL 35294, USA. bhahn@uab.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10649986" target="_blank"〉PubMed〈/a〉

    Description: In eukaryotes, dozens of posttranscriptional modifications are directed to specific nucleotides in ribosomal RNAs (rRNAs) by small nucleolar RNAs (snoRNAs). We identified homologs of snoRNA genes in both branches of the Archaea. Eighteen small sno-like RNAs (sRNAs) were cloned from the archaeon Sulfolobus acidocaldarius by coimmunoprecipitation with archaeal fibrillarin and NOP56, the homologs of eukaryotic snoRNA-associated proteins. We trained a probabilistic model on these sRNAs to search for more sRNAs in archaeal genomic sequences. Over 200 additional sRNAs were identified in seven archaeal genomes representing both the Crenarchaeota and the Euryarchaeota. snoRNA-based rRNA processing was therefore probably present in the last common ancestor of Archaea and Eukarya, predating the evolution of a morphologically distinct nucleolus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Omer, A D -- Lowe, T M -- Russell, A G -- Ebhardt, H -- Eddy, S R -- Dennis, P P -- HG01363/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2000 Apr 21;288(5465):517-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, University of British Columbia, 2146 Health Sciences Mall, Vancouver, BC V6T 1Z3, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10775111" target="_blank"〉PubMed〈/a〉
