    Altruistic helping in human infants and young chimpanzees (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-03-04
    Description: Human beings routinely help others to achieve their goals, even when the helper receives no immediate benefit and the person helped is a stranger. Such altruistic behaviors (toward non-kin) are extremely rare evolutionarily, with some theorists even proposing that they are uniquely human. Here we show that human children as young as 18 months of age (prelinguistic or just-linguistic) quite readily help others to achieve their goals in a variety of different situations. This requires both an understanding of others' goals and an altruistic motivation to help. In addition, we demonstrate similar though less robust skills and motivations in three young chimpanzees.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warneken, Felix -- Tomasello, Michael -- New York, N.Y. -- Science. 2006 Mar 3;311(5765):1301-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental and Comparative Psychology, Max Planck Institute for Evolutionary Anthropology, Deutscher Platz 6, 04103 Leipzig, Germany. warneken@eva.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16513986" target="_blank"〉PubMed〈/a〉

    An antigen produced by splicing of noncontiguous peptides in the reverse order (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-09-09
    Description: CD8-positive T lymphocytes recognize peptides that are usually derived from the degradation of cellular proteins and are presented by class I molecules of the major histocompatibility complex. Here we describe a human minor histocompatibility antigen created by a polymorphism in the SP110 nuclear phosphoprotein gene. The antigenic peptide comprises two noncontiguous SP110 peptide segments spliced together in reverse order to that in which they occur in the predicted SP110 protein. The antigenic peptide could be produced in vitro by incubation of precursor peptides with highly purified 20S proteasomes. Cutting and splicing probably occur within the proteasome by transpeptidation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warren, Edus H -- Vigneron, Nathalie J -- Gavin, Marc A -- Coulie, Pierre G -- Stroobant, Vincent -- Dalet, Alexandre -- Tykodi, Scott S -- Xuereb, Suzanne M -- Mito, Jeffrey K -- Riddell, Stanley R -- Van den Eynde, Benoit J -- CA106512/CA/NCI NIH HHS/ -- CA18029/CA/NCI NIH HHS/ -- P01 CA018029/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2006 Sep 8;313(5792):1444-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Immunology, Clinical Research Division, Fred Hutchinson Cancer Research Center, Seattle, WA 98109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16960008" target="_blank"〉PubMed〈/a〉

    Molecular imaging in cancer (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-05-27
    Description: Medical imaging technologies have undergone explosive growth over the past few decades and now play a central role in clinical oncology. But the truly transformative power of imaging in the clinical management of cancer patients lies ahead. Today, imaging is at a crossroads, with molecularly targeted imaging agents expected to broadly expand the capabilities of conventional anatomical imaging methods. Molecular imaging will allow clinicians to not only see where a tumor is located in the body, but also to visualize the expression and activity of specific molecules (e.g., proteases and protein kinases) and biological processes (e.g., apoptosis, angiogenesis, and metastasis) that influence tumor behavior and/or response to therapy. This information is expected to have a major impact on cancer detection, individualized treatment, and drug development, as well as our understanding of how cancer arises.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weissleder, Ralph -- New York, N.Y. -- Science. 2006 May 26;312(5777):1168-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Molecular Imaging Research, Massachusetts General Hospital, Harvard Medical School, Charlestown, MA 02129, USA. weissleder@helix.mgh.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16728630" target="_blank"〉PubMed〈/a〉

    Language control in the bilingual brain (2006)

    Details
    Publication Date: 2006-06-10
    Description: How does the bilingual brain distinguish and control which language is in use? Previous functional imaging experiments have not been able to answer this question because proficient bilinguals activate the same brain regions irrespective of the language being tested. Here, we reveal that neuronal responses within the left caudate are sensitive to changes in the language or the meaning of words. By demonstrating this effect in populations of German-English and Japanese-English bilinguals, we suggest that the left caudate plays a universal role in monitoring and controlling the language in use.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crinion, J -- Turner, R -- Grogan, A -- Hanakawa, T -- Noppeney, U -- Devlin, J T -- Aso, T -- Urayama, S -- Fukuyama, H -- Stockton, K -- Usui, K -- Green, D W -- Price, C J -- 051067/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Jun 9;312(5779):1537-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Department of Imaging Neuroscience, University College London, London WC1N 3BG, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16763154" target="_blank"〉PubMed〈/a〉

    A clamping mechanism involved in SNARE-dependent exocytosis (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-06-24
    Description: During neurotransmitter release at the synapse, influx of calcium ions stimulates the release of neurotransmitter. However, the mechanism by which synaptic vesicle fusion is coupled to calcium has been unclear, despite the identification of both the core fusion machinery [soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE)] and the principal calcium sensor (synaptotagmin). Here, we describe what may represent a basic principle of the coupling mechanism: a reversible clamping protein (complexin) that can freeze the SNAREpin, an assembled fusion-competent intermediate en route to fusion. When calcium binds to the calcium sensor synaptotagmin, the clamp would then be released. SNARE proteins, and key regulators like synaptotagmin and complexin, can be ectopically expressed on the cell surface. Cells expressing such "flipped" synaptic SNAREs fuse constitutively, but when we coexpressed complexin, fusion was blocked. Adding back calcium triggered fusion from this intermediate in the presence of synaptotagmin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Giraudo, Claudio G -- Eng, William S -- Melia, Thomas J -- Rothman, James E -- New York, N.Y. -- Science. 2006 Aug 4;313(5787):676-80.

    Description: Mekel-Bobrov et al. and Evans et al.

    Group competition, reproductive leveling, and the evolution of human altruism (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-12-13
    Description: Humans behave altruistically in natural settings and experiments. A possible explanation-that groups with more altruists survive when groups compete-has long been judged untenable on empirical grounds for most species. But there have been no empirical tests of this explanation for humans. My empirical estimates show that genetic differences between early human groups are likely to have been great enough so that lethal intergroup competition could account for the evolution of altruism. Crucial to this process were distinctive human practices such as sharing food beyond the immediate family, monogamy, and other forms of reproductive leveling. These culturally transmitted practices presuppose advanced cognitive and linguistic capacities, possibly accounting for the distinctive forms of altruism found in our species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bowles, Samuel -- New York, N.Y. -- Science. 2006 Dec 8;314(5805):1569-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Santa Fe Institute, 1399 Hyde Park Road, Santa Fe, NM 87501, USA, and Universita di Siena, 17 Piazza San Francesco, Siena, Italy. bowles@santafe.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17158320" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 2006-11-04
    Description: One hundred years ago a small group of psychiatrists described the abnormal protein deposits in the brain that define the most common neurodegenerative diseases. Over the past 25 years, it has become clear that the proteins forming the deposits are central to the disease process. Amyloid-beta and tau make up the plaques and tangles of Alzheimer's disease, where these normally soluble proteins assemble into amyloid-like filaments. Tau inclusions are also found in a number of related disorders. Genetic studies have shown that dysfunction of amyloid-beta or tau is sufficient to cause dementia. The ongoing molecular dissection of the neurodegenerative pathways is expected to lead to a true understanding of disease pathogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goedert, Michel -- Spillantini, Maria Grazia -- G0301152/Medical Research Council/United Kingdom -- MC_U105184291/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2006 Nov 3;314(5800):777-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Biology, Medical Research Council, Cambridge CB2 2QH, UK. mg@mrc-lmb.cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17082447" target="_blank"〉PubMed〈/a〉

    Plant volatile compounds: sensory cues for health and nutritional value? (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-14
    Description: Plants produce many volatile metabolites. A small subset of these compounds is sensed by animals and humans, and the volatile profiles are defining elements of the distinct flavors of individual foods. Flavor volatiles are derived from an array of nutrients, including amino acids, fatty acids, and carotenoids. In tomato, almost all of the important flavor-related volatiles are derived from essential nutrients. The predominance of volatiles derived from essential nutrients and health-promoting compounds suggests that these volatiles provide important information about the nutritional makeup of foods. Evidence supporting a relation between volatile perception and nutrient or health value will be reviewed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goff, Stephen A -- Klee, Harry J -- New York, N.Y. -- Science. 2006 Feb 10;311(5762):815-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Syngenta Fellows Group, Syngenta Biotechnology Inc., 3054 Cornwallis Road, Research Triangle Park, NC 27709-2257, USA. stephen.goff@syngenta.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16469919" target="_blank"〉PubMed〈/a〉

    A virulence locus of Pseudomonas aeruginosa encodes a protein secretion apparatus (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-06-10
    Description: Bacterial pathogens frequently use protein secretion to mediate interactions with their hosts. Here we found that a virulence locus (HSI-I) of Pseudomonas aeruginosa encodes a protein secretion apparatus. The apparatus assembled in discrete subcellular locations and exported Hcp1, a hexameric protein that forms rings with a 40 angstrom internal diameter. Regulatory patterns of HSI-I suggested that the apparatus functions during chronic infections. We detected Hcp1 in pulmonary secretions of cystic fibrosis (CF) patients and Hcp1-specific antibodies in their sera. Thus, HSI-I likely contributes to the pathogenesis of P. aeruginosa in CF patients. HSI-I-related loci are widely distributed among bacterial pathogens and may play a general role in mediating host interactions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2800167/" 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/PMC2800167/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mougous, Joseph D -- Cuff, Marianne E -- Raunser, Stefan -- Shen, Aimee -- Zhou, Min -- Gifford, Casey A -- Goodman, Andrew L -- Joachimiak, Grazyna -- Ordonez, Claudia L -- Lory, Stephen -- Walz, Thomas -- Joachimiak, Andrzej -- Mekalanos, John J -- AI21451/AI/NIAID NIH HHS/ -- AI26289/AI/NIAID NIH HHS/ -- GM074942/GM/NIGMS NIH HHS/ -- GM62414/GM/NIGMS NIH HHS/ -- P50 GM062414/GM/NIGMS NIH HHS/ -- P50 GM062414-02/GM/NIGMS NIH HHS/ -- U54 GM074942/GM/NIGMS NIH HHS/ -- U54 GM074942-04S2/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Jun 9;312(5779):1526-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Molecular Genetics, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16763151" target="_blank"〉PubMed〈/a〉

    Emergence of drug-resistant influenza virus: population dynamical considerations (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-04-22
    Description: Given the considerable challenges to the rapid development of an effective vaccine against influenza, antiviral agents will play an important role as a first-line defense if a new pandemic occurs. The large-scale use of drugs for chemoprophylaxis and treatment will impose strong selection for the evolution of drug-resistant strains. The ensuing transmission of those strains could substantially limit the effectiveness of the drugs as a first-line defense. Summarizing recent data on the rate at which the treatment of influenza infection generates resistance de novo and on the transmission fitness of resistant virus, we discuss possible implications for the epidemiological spread of drug resistance in the context of an established population dynamic model.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Regoes, Roland R -- Bonhoeffer, Sebastian -- New York, N.Y. -- Science. 2006 Apr 21;312(5772):389-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Integrative Biology, ETH Zurich, ETH Zentrum CHN K12.1, Universitatsstrasse 16, CH 8092 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16627735" target="_blank"〉PubMed〈/a〉

    Publication Date: 2006-05-27
    Description: The allure of the emerging genomic technologies in cancer is their ability to generate new biomarkers that predict how individual cancer patients will respond to various treatments. However, productive implementation of cancer biomarkers into patient care will require fundamental changes in how we consider approvals for cancer indications and how we track patient responses. Here we briefly describe ongoing efforts to identify and to validate cancer biomarkers, discuss the technological hurdles that lie ahead, and then focus on the more pressing political and cultural issues that, if left unheeded, could derail many of the anticipated benefits of biomarker research.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dalton, William S -- Friend, Stephen H -- New York, N.Y. -- Science. 2006 May 26;312(5777):1165-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉H.

    Publication Date: 2006-12-16
    Description: Kislev et al. (Reports, 2 June 2006, p. 1372) described Neolithic parthenocarpic fig fruits and proposed that they derive from trees propagated only by cuttings and thus represent the first domesticated plant of the Neolithic Revolution. Because parthenocarpic fig trees naturally produce both seeded and seedless fruits and are capable of spontaneous reproduction, we argue that the finds do not necessarily indicate cultivation, nor horticulture predating grain crops.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lev-Yadun, Simcha -- Ne'eman, Gidi -- Abbo, Shahal -- Flaishman, Moshe A -- New York, N.Y. -- Science. 2006 Dec 15;314(5806):1683; author reply 1683.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Faculty of Science and Science Education, University of Haifa-Oranim, Tivon 36006, Israel. levyadun@research.haifa.ac.il〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17170278" target="_blank"〉PubMed〈/a〉

    Genetic variation affects de novo translocation frequency (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-18
    Description: Translocation is one of the most frequently occurring human chromosomal aberrations. The constitutional t(11;22)(q23;q11), which is the only known recurrent non-Robertsonian translocation, represents a good model for studying translocations in humans. Here we demonstrate polymorphisms of the palindromic sequence at the t(11;22) breakpoint that affect the frequency of de novo translocations in sperm from normal males. A typical allele consists of a perfect palindrome, producing ~10-5 de novo t(11;22) translocations. Alleles with an asymmetric center do not form the t(11;22). Our data show the importance of genome sequence on chromosomal rearrangements, a class of human mutation that is thought to be random.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2818512/" 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/PMC2818512/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kato, Takema -- Inagaki, Hidehito -- Yamada, Kouji -- Kogo, Hiroshi -- Ohye, Tamae -- Kowa, Hiroe -- Nagaoka, Kayuri -- Taniguchi, Mariko -- Emanuel, Beverly S -- Kurahashi, Hiroki -- CA39926/CA/NCI NIH HHS/ -- P01 DC002027/DC/NIDCD NIH HHS/ -- P01 DC002027-070006/DC/NIDCD NIH HHS/ -- R01 CA039926/CA/NCI NIH HHS/ -- R01 CA039926-18/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 17;311(5763):971.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Genetics, Institute for Comprehensive Medical Science, Fujita Health University, 1-98 Dengakugakubo, Kutsukake-cho, Toyoake Aichi 470-1192, Japan [corrected]〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16484486" target="_blank"〉PubMed〈/a〉

    Molecular linkage between the kinase ATM and NF-kappaB signaling in response to genotoxic stimuli (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-25
    Description: The transcription factor NF-kappaB modulates apoptotic responses induced by genotoxic stress. We show that NF-kappaB essential modulator (NEMO), the regulatory subunit of IkappaB kinase (IKK) (which phosphorylates the NF-kappaB inhibitor IkappaB), associates with activated ataxia telangiectasia mutated (ATM) after the induction of DNA double-strand breaks. ATM phosphorylates serine-85 of NEMO to promote its ubiquitin-dependent nuclear export. ATM is also exported in a NEMO-dependent manner to the cytoplasm, where it associates with and causes the activation of IKK in a manner dependent on another IKK regulator, a protein rich in glutamate, leucine, lysine, and serine (ELKS). Thus, regulated nuclear shuttling of NEMO links two signaling kinases, ATM and IKK, to activate NF-kappaB by genotoxic signals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Zhao-Hui -- Shi, Yuling -- Tibbetts, Randal S -- Miyamoto, Shigeki -- R01-CA77474/CA/NCI NIH HHS/ -- R01-CA81065/CA/NCI NIH HHS/ -- R01-GM067868/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 24;311(5764):1141-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Wisconsin-Madison, 301 SMI, 1300 University Avenue, Madison, WI 53706, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16497931" target="_blank"〉PubMed〈/a〉

    Description: Nisin is a posttranslationally modified antimicrobial peptide that is widely used as a food preservative. It contains five cyclic thioethers of varying sizes that are installed by a single enzyme, NisC. Reported here are the in vitro reconstitution of the cyclization process and the x-ray crystal structure of the NisC enzyme. The structure reveals similarities in fold and substrate activation with mammalian farnesyl transferases, suggesting that human homologs of NisC posttranslationally modify a cysteine of a protein substrate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Bo -- Yu, John Paul J -- Brunzelle, Joseph S -- Moll, Gert N -- van der Donk, Wilfred A -- Nair, Satish K -- GM58822/GM/NIGMS NIH HHS/ -- R01 GM079038/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Mar 10;311(5766):1464-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Illinois at Urbana-Champaign, 600 South Mathews Avenue, Urbana, IL 61801, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16527981" target="_blank"〉PubMed〈/a〉

    A regulatory SNP causes a human genetic disease by creating a new transcriptional promoter (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-05-27
    Description: We describe a pathogenetic mechanism underlying a variant form of the inherited blood disorder alpha thalassemia. Association studies of affected individuals from Melanesia localized the disease trait to the telomeric region of human chromosome 16, which includes the alpha-globin gene cluster, but no molecular defects were detected by conventional approaches. After resequencing and using a combination of chromatin immunoprecipitation and expression analysis on a tiled oligonucleotide array, we identified a gain-of-function regulatory single-nucleotide polymorphism (rSNP) in a nongenic region between the alpha-globin genes and their upstream regulatory elements. The rSNP creates a new promoterlike element that interferes with normal activation of all downstream alpha-like globin genes. Thus, our work illustrates a strategy for distinguishing between neutral and functionally important rSNPs, and it also identifies a pathogenetic mechanism that could potentially underlie other genetic diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉De Gobbi, Marco -- Viprakasit, Vip -- Hughes, Jim R -- Fisher, Chris -- Buckle, Veronica J -- Ayyub, Helena -- Gibbons, Richard J -- Vernimmen, Douglas -- Yoshinaga, Yuko -- de Jong, Pieter -- Cheng, Jan-Fang -- Rubin, Edward M -- Wood, William G -- Bowden, Don -- Higgs, Douglas R -- MC_U137961143/Medical Research Council/United Kingdom -- MC_U137961145/Medical Research Council/United Kingdom -- MC_U137961147/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2006 May 26;312(5777):1215-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Molecular Haematology Unit, Weatherall Institute of Molecular Medicine, John Radcliffe Hospital, Oxford, OX3 9DS, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16728641" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 2006-08-12
    Description: Long-distance dispersal (LDD) of plants poses challenges to research because it involves rare events driven by complex and highly stochastic processes. The current surge of renewed interest in LDD, motivated by growing recognition of its critical importance for natural populations and communities and for humanity, promises an improved, quantitatively derived understanding of LDD. To gain deep insights into the patterns, mechanisms, causes, and consequences of LDD, we must look beyond the standard dispersal vectors and the mean trend of the distribution of dispersal distances. "Nonstandard" mechanisms such as extreme climatic events and generalized LDD vectors seem to hold the greatest explanatory power for the drastic deviations from the mean trend, deviations that make the nearly impossible LDD a reality.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nathan, Ran -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):786-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Movement Ecology Laboratory, Department of Evolution, Systematics and Ecology, Alexander Silberman Institute of Life Sciences, Hebrew University of Jerusalem, Givat Ram, 91904 Jerusalem, Israel. rnathan@cc.huji.ac.il〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902126" target="_blank"〉PubMed〈/a〉

    HIV decline associated with behavior change in eastern Zimbabwe (2006)

    Details
    Publication Date: 2006-02-04
    Description: Few sub-Saharan African countries have witnessed declines in HIV prevalence, and only Uganda has compelling evidence for a decline founded on sexual behavior change. We report a decline in HIV prevalence in eastern Zimbabwe between 1998 and 2003 associated with sexual behavior change in four distinct socioeconomic strata. HIV prevalence fell most steeply at young ages-by 23 and 49%, respectively, among men aged 17 to 29 years and women aged 15 to 24 years-and in more educated groups. Sexually experienced men and women reported reductions in casual sex of 49 and 22%, respectively, whereas recent cohorts reported delayed sexual debut. Selective AIDS-induced mortality contributed to the decline in HIV prevalence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gregson, Simon -- Garnett, Geoffrey P -- Nyamukapa, Constance A -- Hallett, Timothy B -- Lewis, James J C -- Mason, Peter R -- Chandiwana, Stephen K -- Anderson, Roy M -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Feb 3;311(5761):664-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Infectious Disease Epidemiology, Imperial College London, UK.

    Human hair growth deficiency is linked to a genetic defect in the phospholipase gene LIPH (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-11
    Description: The molecular mechanisms controlling human hair growth and scalp hair loss are poorly understood. By screening about 350,000 individuals in two populations from the Volga-Ural region of Russia, we identified a gene mutation in families who show an inherited form of hair loss and a hair growth defect. Affected individuals were homozygous for a deletion in the LIPH gene on chromosome 3q27, caused by short interspersed nuclear element-retrotransposon-mediated recombination. The LIPH gene is expressed in hair follicles and encodes a phospholipase called lipase H (alternatively known as membrane-associated phosphatidic acid-selective phospholipase A1alpha), an enzyme that regulates the production of bioactive lipids. These results suggest that lipase H participates in hair growth and development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kazantseva, Anastasiya -- Goltsov, Andrey -- Zinchenko, Rena -- Grigorenko, Anastasia P -- Abrukova, Anna V -- Moliaka, Yuri K -- Kirillov, Alexander G -- Guo, Zhiru -- Lyle, Stephen -- Ginter, Evgeny K -- Rogaev, Evgeny I -- K08-AR02179/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Nov 10;314(5801):982-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Brudnick Neuropsychiatric Research Institute, Department of Psychiatry, University of Massachusetts Medical School, 303 Belmont Street, Worcester, MA 01604, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17095700" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 2006-08-12
    Description: Theoretical work suggests that structural properties of naturally occurring networks are important in shaping behavior and dynamics. However, the relationships between structure and behavior are difficult to establish through empirical studies, because the networks in such studies are typically fixed. We studied networks of human subjects attempting to solve the graph or network coloring problem, which models settings in which it is desirable to distinguish one's behavior from that of one's network neighbors. Networks generated by preferential attachment made solving the coloring problem more difficult than did networks based on cyclical structures, and "small worlds" networks were easier still. We also showed that providing more information can have opposite effects on performance, depending on network structure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kearns, Michael -- Suri, Siddharth -- Montfort, Nick -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):824-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of Pennsylvania, Department of Computer and Information Science, 3330 Walnut Street, Philadelphia, PA 19104, USA. mkearns@cis.upenn.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902134" target="_blank"〉PubMed〈/a〉

    Description: The fundamental challenge in the social sciences is moving from complicated correlations to useful prediction. Progress usually reflects an interplay between theory, data, and tools. Six areas of innovation, principally data and tools, are now pushing at the frontiers of these sciences: longitudinal data, laboratory experimentation, improved statistical methods, geographic information tools, biosocial science, and international replication. These innovations are gaining power as they cross disciplinary boundaries, helping to attribute causality to observed relationships, to understand their nature, and thereby to improve the accuracy and usefulness of predictions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Butz, William P -- Torrey, Barbara Boyle -- New York, N.Y. -- Science. 2006 Jun 30;312(5782):1898-900.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Population Reference Bureau, 1875 Connecticut Avenue, Washington, DC 20009, USA. wbutz@prb.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16809524" target="_blank"〉PubMed〈/a〉

    Publication Date: 2006-05-20
    Description: We describe the use of gold nanoparticle-oligonucleotide complexes as intracellular gene regulation agents for the control of protein expression in cells. These oligonucleotide-modified nanoparticles have affinity constants for complementary nucleic acids that are higher than their unmodified oligonucleotide counterparts, are less susceptible to degradation by nuclease activity, exhibit greater than 99% cellular uptake, can introduce oligonucleotides at a higher effective concentration than conventional transfection agents, and are nontoxic to the cells under the conditions studied. By chemically tailoring the density of DNA bound to the surface of gold nanoparticles, we demonstrated a tunable gene knockdown.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosi, Nathaniel L -- Giljohann, David A -- Thaxton, C Shad -- Lytton-Jean, Abigail K R -- Han, Min Su -- Mirkin, Chad A -- New York, N.Y. -- Science. 2006 May 19;312(5776):1027-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and International Institute for Nanotechnology, Northwestern University, 2145 Sheridan Road, Evanston, IL 60208-3113 USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16709779" target="_blank"〉PubMed〈/a〉

    HTRA1 promoter polymorphism in wet age-related macular degeneration (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-10-21
    Description: Age-related macular degeneration (AMD), the most common cause of irreversible vision loss in individuals aged older than 50 years, is classified as either wet (neovascular) or dry (nonneovascular). Inherited variation in the complement factor H gene is a major risk factor for drusen in dry AMD. Here we report that a single-nucleotide polymorphism in the promoter region of HTRA1, a serine protease gene on chromosome 10q26, is a major genetic risk factor for wet AMD.

    Evolutionary history of Salmonella typhi (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-25
    Description: For microbial pathogens, phylogeographic differentiation seems to be relatively common. However, the neutral population structure of Salmonella enterica serovar Typhi reflects the continued existence of ubiquitous haplotypes over millennia. In contrast, clinical use of fluoroquinolones has yielded at least 15 independent gyrA mutations within a decade and stimulated clonal expansion of haplotype H58 in Asia and Africa. Yet, antibiotic-sensitive strains and haplotypes other than H58 still persist despite selection for antibiotic resistance. Neutral evolution in Typhi appears to reflect the asymptomatic carrier state, and adaptive evolution depends on the rapid transmission of phenotypic changes through acute infections.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2652035/" 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/PMC2652035/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roumagnac, Philippe -- Weill, Francois-Xavier -- Dolecek, Christiane -- Baker, Stephen -- Brisse, Sylvain -- Chinh, Nguyen Tran -- Le, Thi Anh Hong -- Acosta, Camilo J -- Farrar, Jeremy -- Dougan, Gordon -- Achtman, Mark -- 076962/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Nov 24;314(5803):1301-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur Infektionsbiologie, Department of Molecular Biology, Chariteplatz 1, 10117 Berlin, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17124322" target="_blank"〉PubMed〈/a〉

    Dual infection with HIV and malaria fuels the spread of both diseases in sub-Saharan Africa (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-12-13
    Description: Mounting evidence has revealed pathological interactions between HIV and malaria in dually infected patients, but the public health implications of the interplay have remained unclear. A transient almost one-log elevation in HIV viral load occurs during febrile malaria episodes; in addition, susceptibility to malaria is enhanced in HIV-infected patients. A mathematical model applied to a setting in Kenya with an adult population of roughly 200,000 estimated that, since 1980, the disease interaction may have been responsible for 8,500 excess HIV infections and 980,000 excess malaria episodes. Co-infection might also have facilitated the geographic expansion of malaria in areas where HIV prevalence is high. Hence, transient and repeated increases in HIV viral load resulting from recurrent co-infection with malaria may be an important factor in promoting the spread of HIV in sub-Saharan Africa.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abu-Raddad, Laith J -- Patnaik, Padmaja -- Kublin, James G -- P30 AI 27757/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 8;314(5805):1603-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Statistical Center for HIV/AIDS Research and Prevention, Fred Hutchinson Cancer Research Center, Seattle, WA 98109, USA. laith@scharp.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17158329" target="_blank"〉PubMed〈/a〉

    High gamma power is phase-locked to theta oscillations in human neocortex (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-09-16
    Description: We observed robust coupling between the high- and low-frequency bands of ongoing electrical activity in the human brain. In particular, the phase of the low-frequency theta (4 to 8 hertz) rhythm modulates power in the high gamma (80 to 150 hertz) band of the electrocorticogram, with stronger modulation occurring at higher theta amplitudes. Furthermore, different behavioral tasks evoke distinct patterns of theta/high gamma coupling across the cortex. The results indicate that transient coupling between low- and high-frequency brain rhythms coordinates activity in distributed cortical areas, providing a mechanism for effective communication during cognitive processing in humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2628289/" 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/PMC2628289/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Canolty, R T -- Edwards, E -- Dalal, S S -- Soltani, M -- Nagarajan, S S -- Kirsch, H E -- Berger, M S -- Barbaro, N M -- Knight, R T -- F31DC006762/DC/NIDCD NIH HHS/ -- NS21135/NS/NINDS NIH HHS/ -- R01 DC004855/DC/NIDCD NIH HHS/ -- R01 DC004855-01A1/DC/NIDCD NIH HHS/ -- R01 NS021135/NS/NINDS NIH HHS/ -- R01 NS021135-20/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2006 Sep 15;313(5793):1626-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Helen Wills Neuroscience Institute, University of California, Berkeley, CA 94720, USA. rcanolty@berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16973878" target="_blank"〉PubMed〈/a〉

    Tequila, a neurotrypsin ortholog, regulates long-term memory formation in Drosophila (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-12
    Description: Mutations in the human neurotrypsin gene are associated with autosomal recessive mental retardation. To further understand the pathophysiological consequences of the lack of this serine protease, we studied Tequila (Teq), the Drosophila neurotrypsin ortholog, using associative memory as a behavioral readout. We found that teq inactivation resulted in a long-term memory (LTM)-specific defect. After LTM conditioning of wild-type flies, teq expression transiently increased in the mushroom bodies. Moreover, specific inhibition of teq expression in adult mushroom bodies resulted in a reversible LTM defect. Hence, the Teq pathway is essential for information processing in Drosophila.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Didelot, Gerard -- Molinari, Florence -- Tchenio, Paul -- Comas, Daniel -- Milhiet, Elodie -- Munnich, Arnold -- Colleaux, Laurence -- Preat, Thomas -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):851-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genes et Dynamique des Systemes de Memoire, UMR CNRS 7637, Ecole Superieure de Physique et de Chimie Industrielles, 10 Rue Vauquelin 75005 Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902143" target="_blank"〉PubMed〈/a〉

    An essential role for LEDGF/p75 in HIV integration (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-09-09
    Description: Chromosomal integration enables human immunodeficiency virus (HIV) to establish a permanent reservoir that can be therapeutically suppressed but not eradicated. Participation of cellular proteins in this obligate replication step is poorly understood. We used intensified RNA interference and dominant-negative protein approaches to show that the cellular transcriptional coactivator lens epithelium-derived growth factor (LEDGF)/p75 (p75) is an essential HIV integration cofactor. The mechanism requires both linkages of a molecular tether that p75 forms between integrase and chromatin. Fractionally minute levels of endogenous p75 are sufficient to enable integration, showing that cellular factors that engage HIV after entry may elude identification in less intensive knockdowns. Perturbing the p75-integrase interaction may have therapeutic potential.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Llano, Manuel -- Saenz, Dyana T -- Meehan, Anne -- Wongthida, Phonphimon -- Peretz, Mary -- Walker, William H -- Teo, Wulin -- Poeschla, Eric M -- New York, N.Y. -- Science. 2006 Oct 20;314(5798):461-4.

    Sequencing and analysis of Neanderthal genomic DNA (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-18
    Description: Our knowledge of Neanderthals is based on a limited number of remains and artifacts from which we must make inferences about their biology, behavior, and relationship to ourselves. Here, we describe the characterization of these extinct hominids from a new perspective, based on the development of a Neanderthal metagenomic library and its high-throughput sequencing and analysis. Several lines of evidence indicate that the 65,250 base pairs of hominid sequence so far identified in the library are of Neanderthal origin, the strongest being the ascertainment of sequence identities between Neanderthal and chimpanzee at sites where the human genomic sequence is different. These results enabled us to calculate the human-Neanderthal divergence time based on multiple randomly distributed autosomal loci. Our analyses suggest that on average the Neanderthal genomic sequence we obtained and the reference human genome sequence share a most recent common ancestor approximately 706,000 years ago, and that the human and Neanderthal ancestral populations split approximately 370,000 years ago, before the emergence of anatomically modern humans. Our finding that the Neanderthal and human genomes are at least 99.5% identical led us to develop and successfully implement a targeted method for recovering specific ancient DNA sequences from metagenomic libraries. This initial analysis of the Neanderthal genome advances our understanding of the evolutionary relationship of Homo sapiens and Homo neanderthalensis and signifies the dawn of Neanderthal genomics.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2583069/" 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/PMC2583069/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Noonan, James P -- Coop, Graham -- Kudaravalli, Sridhar -- Smith, Doug -- Krause, Johannes -- Alessi, Joe -- Chen, Feng -- Platt, Darren -- Paabo, Svante -- Pritchard, Jonathan K -- Rubin, Edward M -- 1-F32-GM074367/GM/NIGMS NIH HHS/ -- HL066681/HL/NHLBI NIH HHS/ -- R01 HG002772/HG/NHGRI NIH HHS/ -- R01 HG002772-01/HG/NHGRI NIH HHS/ -- R01 HG002772-1/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2006 Nov 17;314(5802):1113-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉U.S. Department of Energy Joint Genome Institute, 2800 Mitchell Drive, Walnut Creek, CA 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17110569" target="_blank"〉PubMed〈/a〉

    When does "economic man" dominate social behavior? (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-01-10
    Description: The canonical model in economics considers people to be rational and self-regarding. However, much evidence challenges this view, raising the question of when "Economic Man" dominates the outcome of social interactions, and when bounded rationality or other-regarding preferences dominate. Here we show that strategic incentives are the key to answering this question. A minority of self-regarding individuals can trigger a "noncooperative" aggregate outcome if their behavior generates incentives for the majority of other-regarding individuals to mimic the minority's behavior. Likewise, a minority of other-regarding individuals can generate a "cooperative" aggregate outcome if their behavior generates incentives for a majority of self-regarding people to behave cooperatively. Similarly, in strategic games, aggregate outcomes can be either far from or close to Nash equilibrium if players with high degrees of strategic thinking mimic or erase the effects of others who do very little strategic thinking. Recently developed theories of other-regarding preferences and bounded rationality explain these findings and provide better predictions of actual aggregate behavior than does traditional economic theory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Camerer, Colin F -- Fehr, Ernst -- New York, N.Y. -- Science. 2006 Jan 6;311(5757):47-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉California Institute of Technology, Pasadena, CA 91125, USA. camerer@hss.caltech.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16400140" target="_blank"〉PubMed〈/a〉

    On making the right choice: the deliberation-without-attention effect (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-18
    Description: Contrary to conventional wisdom, it is not always advantageous to engage in thorough conscious deliberation before choosing. On the basis of recent insights into the characteristics of conscious and unconscious thought, we tested the hypothesis that simple choices (such as between different towels or different sets of oven mitts) indeed produce better results after conscious thought, but that choices in complex matters (such as between different houses or different cars) should be left to unconscious thought. Named the "deliberation-without-attention" hypothesis, it was confirmed in four studies on consumer choice, both in the laboratory as well as among actual shoppers, that purchases of complex products were viewed more favorably when decisions had been made in the absence of attentive deliberation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dijksterhuis, Ap -- Bos, Maarten W -- Nordgren, Loran F -- van Baaren, Rick B -- New York, N.Y. -- Science. 2006 Feb 17;311(5763):1005-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of Amsterdam, Roetersstraat 15, 1018 WB, Amsterdam, the Netherlands. a.j.dijksterhuis@uva.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16484496" target="_blank"〉PubMed〈/a〉

    Five rules for the evolution of cooperation (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-12-13
    Description: Cooperation is needed for evolution to construct new levels of organization. Genomes, cells, multicellular organisms, social insects, and human society are all based on cooperation. Cooperation means that selfish replicators forgo some of their reproductive potential to help one another. But natural selection implies competition and therefore opposes cooperation unless a specific mechanism is at work. Here I discuss five mechanisms for the evolution of cooperation: kin selection, direct reciprocity, indirect reciprocity, network reciprocity, and group selection. For each mechanism, a simple rule is derived that specifies whether natural selection can lead to cooperation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3279745/" 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/PMC3279745/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nowak, Martin A -- 1R01GM078986-01/GM/NIGMS NIH HHS/ -- R01 GM078986/GM/NIGMS NIH HHS/ -- R01 GM078986-04/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 8;314(5805):1560-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program for Evolutionary Dynamics, Department of Organismic and Evolutionary Biology, and Department of Mathematics, Harvard University, Cambridge, MA 02138, USA. martin_nowak@harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17158317" target="_blank"〉PubMed〈/a〉

    ATP release guides neutrophil chemotaxis via P2Y2 and A3 receptors (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-12-16
    Description: Cells must amplify external signals to orient and migrate in chemotactic gradient fields. We find that human neutrophils release adenosine triphosphate (ATP) from the leading edge of the cell surface to amplify chemotactic signals and direct cell orientation by feedback through P2Y2 nucleotide receptors. Neutrophils rapidly hydrolyze released ATP to adenosine that then acts via A3-type adenosine receptors, which are recruited to the leading edge, to promote cell migration. Thus, ATP release and autocrine feedback through P2Y2 and A3 receptors provide signal amplification, controlling gradient sensing and migration of neutrophils.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Yu -- Corriden, Ross -- Inoue, Yoshiaki -- Yip, Linda -- Hashiguchi, Naoyuki -- Zinkernagel, Annelies -- Nizet, Victor -- Insel, Paul A -- Junger, Wolfgang G -- GM-60475/GM/NIGMS NIH HHS/ -- GM-66232/GM/NIGMS NIH HHS/ -- PR043034/PR/OCPHP CDC HHS/ -- R01 GM-51477/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 15;314(5806):1792-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Surgery, University of California San Diego, San Diego, CA 92103, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17170310" target="_blank"〉PubMed〈/a〉

    Extending top-down mass spectrometry to proteins with masses greater than 200 kilodaltons (2006)

    Description: For characterization of sequence and posttranslational modifications, molecular and fragment ion mass data from ionizing and dissociating a protein in the mass spectrometer are far more specific than are masses of peptides from the protein's digestion. We extend the approximately 500-residue, approximately 50-kilodalton (kD) dissociation limitation of this top-down methodology by using electrospray additives, heated vaporization, and separate noncovalent and covalent bond dissociation. This process can cleave 287 interresidue bonds in the termini of a 1314-residue (144-kD) protein, specify previously unidentified disulfide bonds between 8 of 27 cysteines in a 1714-residue (200-kD) protein, and correct sequence predictions in two proteins, one with 2153 residues (229 kD).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Han, Xuemei -- Jin, Mi -- Breuker, Kathrin -- McLafferty, Fred W -- GM16609/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Oct 6;314(5796):109-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Chemical Biology, Baker Laboratory, Cornell University, Ithaca, NY 14853, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17023655" target="_blank"〉PubMed〈/a〉

    Lamin A-dependent nuclear defects in human aging (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-04-29
    Description: Mutations in the nuclear structural protein lamin A cause the premature aging syndrome Hutchinson-Gilford progeria (HGPS). Whether lamin A plays any role in normal aging is unknown. We show that the same molecular mechanism responsible for HGPS is active in healthy cells. Cell nuclei from old individuals acquire defects similar to those of HGPS patient cells, including changes in histone modifications and increased DNA damage. Age-related nuclear defects are caused by sporadic use, in healthy individuals, of the same cryptic splice site in lamin A whose constitutive activation causes HGPS. Inhibition of this splice site reverses the nuclear defects associated with aging. These observations implicate lamin A in physiological aging.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1855250/" 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/PMC1855250/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scaffidi, Paola -- Misteli, Tom -- Z01 BC010309-07/BC/NCI NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2006 May 19;312(5776):1059-63.

    Details
    Publication Date: 2006-07-29
    Description: The cross-species transmission of lentiviruses from African primates to humans has selected viral adaptations which have subsequently facilitated human-to-human transmission. HIV adapts not only by positive selection through mutation but also by recombination of segments of its genome in individuals who become multiply infected. Naturally infected nonhuman primates are relatively resistant to AIDS-like disease despite high plasma viral loads and sustained viral evolution. Further understanding of host resistance factors and the mechanisms of disease in natural primate hosts may provide insight into unexplored therapeutic avenues for the prevention of AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heeney, Jonathan L -- Dalgleish, Angus G -- Weiss, Robin A -- G8712499/Medical Research Council/United Kingdom -- P01 A148225-01A2/PHS HHS/ -- New York, N.Y. -- Science. 2006 Jul 28;313(5786):462-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Virology, Biomedical Primate Research Centre, Rijswijk 2280 GH, Netherlands. heeney@bprc.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16873637" target="_blank"〉PubMed〈/a〉

Because C. novyi-NT lyses red blood cells, we hypothesized that its membrane-disrupting properties could be exploited to enhance the release of liposome-encapsulated drugs within tumors. Here, we show that treatment of mice bearing large, established tumors with C. novyi-NT plus a single dose of liposomal doxorubicin often led to eradication of the tumors. The bacterial factor responsible for the enhanced drug release was identified as a previously unrecognized protein termed liposomase. This protein could potentially be incorporated into diverse experimental approaches for the specific delivery of chemotherapeutic agents to tumors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cheong, Ian -- Huang, Xin -- Bettegowda, Chetan -- Diaz, Luis A Jr -- Kinzler, Kenneth W -- Zhou, Shibin -- Vogelstein, Bert -- CA062924/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2006 Nov 24;314(5803):1308-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and the Ludwig Center for Cancer Genetics and Therapeutics, Johns Hopkins Kimmel Comprehensive Cancer Center, Baltimore, MD 21231, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17124324" target="_blank"〉PubMed〈/a〉

    Large-scale sequence analysis of avian influenza isolates (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-01-28
    Description: The spread of H5N1 avian influenza viruses (AIVs) from China to Europe has raised global concern about their potential to infect humans and cause a pandemic. In spite of their substantial threat to human health, remarkably little AIV whole-genome information is available. We report here a preliminary analysis of the first large-scale sequencing of AIVs, including 2196 AIV genes and 169 complete genomes. We combine this new information with public AIV data to identify new gene alleles, persistent genotypes, compensatory mutations, and a potential virulence determinant.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Obenauer, John C -- Denson, Jackie -- Mehta, Perdeep K -- Su, Xiaoping -- Mukatira, Suraj -- Finkelstein, David B -- Xu, Xiequn -- Wang, Jinhua -- Ma, Jing -- Fan, Yiping -- Rakestraw, Karen M -- Webster, Robert G -- Hoffmann, Erich -- Krauss, Scott -- Zheng, Jie -- Zhang, Ziwei -- Naeve, Clayton W -- AI95357/AI/NIAID NIH HHS/ -- CA 21765/CA/NCI NIH HHS/ -- R01 GM061739/GM/NIGMS NIH HHS/ -- R01 GM069916/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Mar 17;311(5767):1576-80.

    ATM engages autodegradation of the E3 ubiquitin ligase COP1 after DNA damage (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-26
    Description: The ataxia telangiectasia mutated (ATM) protein kinase is a critical component of a DNA-damage response network configured to maintain genomic integrity. The abundance of an essential downstream effecter of this pathway, the tumor suppressor protein p53, is tightly regulated by controlled degradation through COP1 and other E3 ubiquitin ligases, such as MDM2 and Pirh2; however, the signal transduction pathway that regulates the COP1-p53 axis following DNA damage remains enigmatic. We observed that in response to DNA damage, ATM phosphorylated COP1 on Ser(387) and stimulated a rapid autodegradation mechanism. Ionizing radiation triggered an ATM-dependent movement of COP1 from the nucleus to the cytoplasm, and ATM-dependent phosphorylation of COP1 on Ser(387) was both necessary and sufficient to disrupt the COP1-p53 complex and subsequently to abrogate the ubiquitination and degradation of p53. Furthermore, phosphorylation of COP1 on Ser(387) was required to permit p53 to become stabilized and to exert its tumor suppressor properties in response to DNA damage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dornan, David -- Shimizu, Harumi -- Mah, Angie -- Dudhela, Tanay -- Eby, Michael -- O'rourke, Karen -- Seshagiri, Somasekar -- Dixit, Vishva M -- New York, N.Y. -- Science. 2006 Aug 25;313(5790):1122-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiological Chemistry, Genentech, Inc., 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/16931761" target="_blank"〉PubMed〈/a〉

    Neurochemical modulation of response inhibition and probabilistic learning in humans (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-14
    Description: Cognitive functions dependent on the prefrontal cortex, such as the ability to suppress behavior (response inhibition) and to learn from complex feedback (probabilistic learning), play critical roles in activities of daily life. To what extent do different neurochemical systems modulate these two cognitive functions? Here, using stop-signal and probabilistic learning tasks, we show a double dissociation for the involvement of noradrenaline and serotonin in human cognition. In healthy volunteers, inhibition of central noradrenaline reuptake improved response inhibition but had no effect on probabilistic learning, whereas inhibition of central serotonin reuptake impaired probabilistic learning with no effect on response inhibition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1867315/" 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/PMC1867315/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chamberlain, Samuel R -- Muller, Ulrich -- Blackwell, Andrew D -- Clark, Luke -- Robbins, Trevor W -- Sahakian, Barbara J -- 076274/Wellcome Trust/United Kingdom -- G0001354/Medical Research Council/United Kingdom -- G0401099/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Feb 10;311(5762):861-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, University of Cambridge School of Clinical Medicine, Addenbrooke's Hospital, Box 189, Cambridge CB2 2QQ, UK. src33@cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16469930" target="_blank"〉PubMed〈/a〉

    S6K1- and betaTRCP-mediated degradation of PDCD4 promotes protein translation and cell growth (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-10-21
    Description: The tumor suppressor programmed cell death protein 4 (PDCD4) inhibits the translation initiation factor eIF4A, an RNA helicase that catalyzes the unwinding of secondary structure at the 5' untranslated region (5'UTR) of messenger RNAs (mRNAs). In response to mitogens, PDCD4 was rapidly phosphorylated on Ser67 by the protein kinase S6K1 and subsequently degraded via the ubiquitin ligase SCF(betaTRCP). Expression in cultured cells of a stable PDCD4 mutant that is unable to bind betaTRCP inhibited translation of an mRNA with a structured 5'UTR, resulted in smaller cell size, and slowed down cell cycle progression. We propose that regulated degradation of PDCD4 in response to mitogens allows efficient protein synthesis and consequently cell growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dorrello, N Valerio -- Peschiaroli, Angelo -- Guardavaccaro, Daniele -- Colburn, Nancy H -- Sherman, Nicholas E -- Pagano, Michele -- R01-CA76584/CA/NCI NIH HHS/ -- R01-GM57587/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Oct 20;314(5798):467-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, NYU Cancer Institute, New York University School of Medicine, 550 First Avenue, MSB 599, New York, NY 10016, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17053147" target="_blank"〉PubMed〈/a〉

    Electric fields at the active site of an enzyme: direct comparison of experiment with theory (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-07-15
    Description: The electric fields produced in folded proteins influence nearly every aspect of protein function. We present a vibrational spectroscopy technique that measures changes in electric field at a specific site of a protein as shifts in frequency (Stark shifts) of a calibrated nitrile vibration. A nitrile-containing inhibitor is used to deliver a unique probe vibration to the active site of human aldose reductase, and the response of the nitrile stretch frequency is measured for a series of mutations in the enzyme active site. These shifts yield quantitative information on electric fields that can be directly compared with electrostatics calculations. We show that extensive molecular dynamics simulations and ensemble averaging are required to reproduce the observed changes in field.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suydam, Ian T -- Snow, Christopher D -- Pande, Vijay S -- Boxer, Steven G -- New York, N.Y. -- Science. 2006 Jul 14;313(5784):200-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Stanford University, Stanford, CA 94305-5080, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16840693" target="_blank"〉PubMed〈/a〉
