    A century of Alzheimer's disease (2006)
    American Association for the Advancement of Science (AAAS)
    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〉

    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〉

    American Association for the Advancement of Science (AAAS)
    Details
    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.

    Evolution of hormone-receptor complexity by molecular exploitation (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-04-08
    Description: According to Darwinian theory, complexity evolves by a stepwise process of elaboration and optimization under natural selection. Biological systems composed of tightly integrated parts seem to challenge this view, because it is not obvious how any element's function can be selected for unless the partners with which it interacts are already present. Here we demonstrate how an integrated molecular system-the specific functional interaction between the steroid hormone aldosterone and its partner the mineralocorticoid receptor-evolved by a stepwise Darwinian process. Using ancestral gene resurrection, we show that, long before the hormone evolved, the receptor's affinity for aldosterone was present as a structural by-product of its partnership with chemically similar, more ancient ligands. Introducing two amino acid changes into the ancestral sequence recapitulates the evolution of present-day receptor specificity. Our results indicate that tight interactions can evolve by molecular exploitation-recruitment of an older molecule, previously constrained for a different role, into a new functional complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bridgham, Jamie T -- Carroll, Sean M -- Thornton, Joseph W -- F32-GM074398/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Apr 7;312(5770):97-101.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Ecology and Evolutionary Biology, University of Oregon, Eugene, OR 97403, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16601189" target="_blank"〉PubMed〈/a〉

    Rice domestication by reducing shattering (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-03-11
    Description: Crop domestication frequently began with the selection of plants that did not naturally shed ripe fruits or seeds. The reduction in grain shattering that led to cereal domestication involved genetic loci of large effect. The molecular basis of this key domestication transition, however, remains unknown. Here we show that human selection of an amino acid substitution in the predicted DNA binding domain encoded by a gene of previously unknown function was primarily responsible for the reduction of grain shattering in rice domestication. The substitution undermined the gene function necessary for the normal development of an abscission layer that controls the separation of a grain from the pedicel.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Changbao -- Zhou, Ailing -- Sang, Tao -- New York, N.Y. -- Science. 2006 Mar 31;311(5769):1936-9.

    Ammonia channel couples glutaminase with transamidase reactions in GatCAB (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-07-01
    Description: The formation of glutaminyl transfer RNA (Gln-tRNA(Gln)) differs among the three domains of life. Most bacteria employ an indirect pathway to produce Gln-tRNA(Gln) by a heterotrimeric glutamine amidotransferase CAB (GatCAB) that acts on the misacylated Glu-tRNA(Gln). Here, we describe a series of crystal structures of intact GatCAB from Staphylococcus aureus in the apo form and in the complexes with glutamine, asparagine, Mn2+, and adenosine triphosphate analog. Two identified catalytic centers for the glutaminase and transamidase reactions are markedly distant but connected by a hydrophilic ammonia channel 30 A in length. Further, we show that the first U-A base pair in the acceptor stem and the D loop of tRNA(Gln) serve as identity elements essential for discrimination by GatCAB and propose a complete model for the overall concerted reactions to synthesize Gln-tRNA(Gln).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakamura, Akiyoshi -- Yao, Min -- Chimnaronk, Sarin -- Sakai, Naoki -- Tanaka, Isao -- New York, N.Y. -- Science. 2006 Jun 30;312(5782):1954-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Faculty of Advanced Life Sciences, Hokkaido University, Sapporo 060-0810, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16809541" target="_blank"〉PubMed〈/a〉

    Selective silencing of foreign DNA with low GC content by the H-NS protein in Salmonella (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-06-10
    Description: Horizontal gene transfer plays a major role in microbial evolution. However, newly acquired sequences can decrease fitness unless integrated into preexisting regulatory networks. We found that the histone-like nucleoid structuring protein (H-NS) selectively silences horizontally acquired genes by targeting sequences with GC content lower than the resident genome. Mutations in hns are lethal in Salmonella unless accompanied by compensatory mutations in other regulatory loci. Thus, H-NS provides a previously unrecognized mechanism of bacterial defense against foreign DNA, enabling the acquisition of DNA from exogenous sources while avoiding detrimental consequences from unregulated expression of newly acquired genes. Characteristic GC/AT ratios of bacterial genomes may facilitate discrimination between a cell's own DNA and foreign DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Navarre, William Wiley -- Porwollik, Steffen -- Wang, Yipeng -- McClelland, Michael -- Rosen, Henry -- Libby, Stephen J -- Fang, Ferric C -- AI034829/AI/NIAID NIH HHS/ -- AI049417/AI/NIAID NIH HHS/ -- AI052237/AI/NIAID NIH HHS/ -- AI057733/AI/NIAID NIH HHS/ -- AI39557/AI/NIAID NIH HHS/ -- AI48622/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2006 Jul 14;313(5784):236-8.

    alphaE-catenin controls cerebral cortical size by regulating the hedgehog signaling pathway (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-03-18
    Description: During development, cells monitor and adjust their rates of accumulation to produce organs of predetermined size. We show here that central nervous system-specific deletion of the essential adherens junction gene, alphaE-catenin, causes abnormal activation of the hedgehog pathway, resulting in shortening of the cell cycle, decreased apoptosis, and cortical hyperplasia. We propose that alphaE-catenin connects cell-density-dependent adherens junctions with the developmental hedgehog pathway and that this connection may provide a negative feedback loop controlling the size of developing cerebral cortex.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2556178/" 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/PMC2556178/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lien, Wen-Hui -- Klezovitch, Olga -- Fernandez, Tania E -- Delrow, Jeff -- Vasioukhin, Valeri -- P41 RR011823/RR/NCRR NIH HHS/ -- P41 RR011823-128171/RR/NCRR NIH HHS/ -- R01 CA098161/CA/NCI NIH HHS/ -- R01 CA098161-01A1/CA/NCI NIH HHS/ -- R01 CA098161-02/CA/NCI NIH HHS/ -- R01 CA098161-03/CA/NCI NIH HHS/ -- R01 CA098161-04/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2006 Mar 17;311(5767):1609-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Human Biology, 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/16543460" target="_blank"〉PubMed〈/a〉

    A bacterial virulence protein suppresses host innate immunity to cause plant disease (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-07-15
    Description: Plants have evolved a powerful immune system to defend against infection by most microbial organisms. However, successful pathogens, such as Pseudomonas syringae, have developed countermeasures and inject virulence proteins into the host plant cell to suppress immunity and cause devastating diseases. Despite intensive research efforts, the molecular targets of bacterial virulence proteins that are important for plant disease development have remained obscure. Here, we show that a conserved P. syringae virulence protein, HopM1, targets an immunity-associated protein, AtMIN7, in Arabidopsis thaliana. HopM1 mediates the destruction of AtMIN7 via the host proteasome. Our results illustrate a strategy by which a bacterial pathogen exploits the host proteasome to subvert host immunity and causes infection in plants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nomura, Kinya -- Debroy, Sruti -- Lee, Yong Hoon -- Pumplin, Nathan -- Jones, Jonathan -- He, Sheng Yang -- New York, N.Y. -- Science. 2006 Jul 14;313(5784):220-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Energy Plant Research Laboratory, Michigan State University, East Lansing, MI 48824, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16840699" target="_blank"〉PubMed〈/a〉

    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〉

    The mevalonate pathway controls heart formation in Drosophila by isoprenylation of Ggamma1 (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-07-22
    Description: The early morphogenetic mechanisms involved in heart formation are evolutionarily conserved. A screen for genes that control Drosophila heart development revealed a cardiac defect in which pericardial and cardial cells dissociate, which causes loss of cardiac function and embryonic lethality. This phenotype resulted from mutations in the genes encoding HMG-CoA reductase, downstream enzymes in the mevalonate pathway, and G protein Ggamma1, which is geranylgeranylated, thus representing an end point of isoprenoid biosynthesis. Our findings reveal a cardial cell-autonomous requirement of Ggamma1 geranylgeranylation for heart formation and suggest the involvement of the mevalonate pathway in congenital heart disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yi, Peng -- Han, Zhe -- Li, Xiumin -- Olson, Eric N -- New York, N.Y. -- Science. 2006 Sep 1;313(5791):1301-3.

    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〉

    Integration of plant responses to environmentally activated phytohormonal signals (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-01-10
    Description: Plants live in fixed locations and survive adversity by integrating growth responses to diverse environmental signals. Here, we show that the nuclear-localized growth-repressing DELLA proteins of Arabidopsis integrate responses to independent hormonal and environmental signals of adverse conditions. The growth restraint conferred by DELLA proteins is beneficial and promotes survival. We propose that DELLAs permit flexible and appropriate modulation of plant growth in response to changes in natural environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Achard, Patrick -- Cheng, Hui -- De Grauwe, Liesbeth -- Decat, Jan -- Schoutteten, Hermien -- Moritz, Thomas -- Van Der Straeten, Dominique -- Peng, Jinrong -- Harberd, Nicholas P -- New York, N.Y. -- Science. 2006 Jan 6;311(5757):91-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉John Innes Centre, Norwich NR4 7UJ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16400150" target="_blank"〉PubMed〈/a〉

    Losartan, an AT1 antagonist, prevents aortic aneurysm in a mouse model of Marfan syndrome (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-04-08
    Description: Aortic aneurysm and dissection are manifestations of Marfan syndrome (MFS), a disorder caused by mutations in the gene that encodes fibrillin-1. Selected manifestations of MFS reflect excessive signaling by the transforming growth factor-beta (TGF-beta) family of cytokines. We show that aortic aneurysm in a mouse model of MFS is associated with increased TGF-beta signaling and can be prevented by TGF-beta antagonists such as TGF-beta-neutralizing antibody or the angiotensin II type 1 receptor (AT1) blocker, losartan. AT1 antagonism also partially reversed noncardiovascular manifestations of MFS, including impaired alveolar septation. These data suggest that losartan, a drug already in clinical use for hypertension, merits investigation as a therapeutic strategy for patients with MFS and has the potential to prevent the major life-threatening manifestation of this disorder.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1482474/" 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/PMC1482474/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Habashi, Jennifer P -- Judge, Daniel P -- Holm, Tammy M -- Cohn, Ronald D -- Loeys, Bart L -- Cooper, Timothy K -- Myers, Loretha -- Klein, Erin C -- Liu, Guosheng -- Calvi, Carla -- Podowski, Megan -- Neptune, Enid R -- Halushka, Marc K -- Bedja, Djahida -- Gabrielson, Kathleen -- Rifkin, Daniel B -- Carta, Luca -- Ramirez, Francesco -- Huso, David L -- Dietz, Harry C -- K08 HL067056/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2006 Apr 7;312(5770):117-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Pediatrics, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16601194" target="_blank"〉PubMed〈/a〉

    Origins of HIV and the evolution of resistance to AIDS (2006)
    American Association for the Advancement of Science (AAAS)
    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〉

    A bacterial protein enhances the release and efficacy of liposomal cancer drugs (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-25
    Description: Clostridium novyi-NT is an anaerobic bacterium that can infect hypoxic regions within experimental tumors. 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〉

    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〉

    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〉

    Checkpoint proteins control survival of the postmitotic cells in Caenorhabditis elegans (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-06-03
    Description: Checkpoints are evolutionarily conserved signaling mechanisms that arrest cell division and alter cellular stress resistance in response to DNA damage or stalled replication forks. To study the consequences of loss of checkpoint functions in whole animals, checkpoint genes were inactivated in the nematode C. elegans. We show that checkpoint proteins are not only essential for normal development but also determine adult somatic maintenance. Checkpoint proteins play a role in the survival of postmitotic adult cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2568993/" 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/PMC2568993/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olsen, Anders -- Vantipalli, Maithili C -- Lithgow, Gordon J -- AG21069/AG/NIA NIH HHS/ -- AG22868/AG/NIA NIH HHS/ -- NS050789-01/NS/NINDS NIH HHS/ -- R01 AG021069/AG/NIA NIH HHS/ -- R01 AG021069-04/AG/NIA NIH HHS/ -- R01 AG022868/AG/NIA NIH HHS/ -- R01 AG022868-04/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2006 Jun 2;312(5778):1381-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Buck Institute, 8001 Redwood Boulevard, Novato, CA 94945, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16741121" target="_blank"〉PubMed〈/a〉

    Publication Date: 2006-07-11
    Description: The evolution of new combinations of bacterial properties contributes to biodiversity and the emergence of new diseases. We investigated the capacity for bacterial divergence with a chemostat culture of Escherichia coli. A clonal population radiated into more than five phenotypic clusters within 26 days, with multiple variations in global regulation, metabolic strategies, surface properties, and nutrient permeability pathways. Most isolates belonged to a single ecotype, and neither periodic selection events nor ecological competition for a single niche prevented an adaptive radiation with a single resource. The multidirectional exploration of fitness space is an underestimated ingredient to bacterial success even in unstructured environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maharjan, Ram -- Seeto, Shona -- Notley-McRobb, Lucinda -- Ferenci, Thomas -- New York, N.Y. -- Science. 2006 Jul 28;313(5786):514-7.

    How fast was wild wheat domesticated? (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-04-01
    Description: Prehistoric cultivation of wild wheat in the Fertile Crescent led to the selection of mutants with indehiscent (nonshattering) ears, which evolved into modern domestic wheat. Previous estimates suggested that this transformation was rapid, but our analyses of archaeological plant remains demonstrate that indehiscent domesticates were slow to appear, emerging approximately 9500 years before the present, and that dehiscent (shattering) forms were still common in cultivated fields approximately 7500 years before the present. Slow domestication implies that after cultivation began, wild cereals may have remained unchanged for a long period, supporting claims that agriculture originated in the Near East approximately 10,500 years before the present.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tanno, Ken-Ichi -- Willcox, George -- New York, N.Y. -- Science. 2006 Mar 31;311(5769):1886.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Institute for Humanity and Nature, Takashima 335, Kamigyo, 602-0878 Kyoto, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16574859" target="_blank"〉PubMed〈/a〉

    Gene transposition as a cause of hybrid sterility in Drosophila (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-09-09
    Description: We describe reproductive isolation caused by a gene transposition. In certain Drosophila melanogaster-D. simulans hybrids, hybrid male sterility is caused by the lack of a single-copy gene essential for male fertility, JYAlpha. This gene is located on the fourth chromosome of D. melanogaster but on the third chromosome of D. simulans. Genomic and molecular analyses show that JYAlpha transposed to the third chromosome during the evolutionary history of the D. simulans lineage. Because of this transposition, a fraction of hybrids completely lack JYAlpha and are sterile, representing reproductive isolation without sequence evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Masly, John P -- Jones, Corbin D -- Noor, Mohamed A F -- Locke, John -- Orr, H Allen -- New York, N.Y. -- Science. 2006 Sep 8;313(5792):1448-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Rochester, Rochester, NY 14627, USA. msly@mail.rochester.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16960009" target="_blank"〉PubMed〈/a〉

    Publication Date: 2006-07-01
    Description: The study of politics and the life cycle began with a rather single-minded focus on childhood and the family-on the idea, as Tocqueville famously put it, that the entire person could be "seen in the cradle of the child." Politics does begin in childhood, and parents do influence their offspring, but change takes place over the entire span of life. I take up the early emergence of partisanship and essentialism, the formation of generations, politically consequential transitions in adulthood, and the rising of politics and its final decline.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kinder, Donald R -- New York, N.Y. -- Science. 2006 Jun 30;312(5782):1905-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Political Science, University of Michigan, Ann Arbor, MI 48106, USA. drkinder@umich.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16809527" target="_blank"〉PubMed〈/a〉

    Hoxa2- and rhombomere-dependent development of the mouse facial somatosensory map (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-12
    Description: In the mouse trigeminal pathway, sensory inputs from distinct facial structures, such as whiskers or lower jaw and lip, are topographically mapped onto the somatosensory cortex through relay stations in the thalamus and hindbrain. In the developing hindbrain, the mechanisms generating such maps remain elusive. We found that in the principal sensory nucleus, the whisker-related map is contributed by rhombomere 3-derived neurons, whereas the rhombomere 2-derived progeny supply the lower jaw and lip representation. Moreover, early Hoxa2 expression in neuroepithelium prevents the trigeminal nerve from ectopically projecting to the cerebellum, whereas late expression in the principal sensory nucleus promotes selective arborization of whisker-related afferents and topographic connectivity to the thalamus. Hoxa2 inactivation further results in the absence of whisker-related maps in the postnatal brain. Thus, Hoxa2- and rhombomere 3-dependent cues determine the whisker area map and are required for the assembly of the whisker-to-barrel somatosensory circuit.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Oury, Franck -- Murakami, Yasunori -- Renaud, Jean-Sebastien -- Pasqualetti, Massimo -- Charnay, Patrick -- Ren, Shu-Yue -- Rijli, Filippo M -- New York, N.Y. -- Science. 2006 Sep 8;313(5792):1408-13.

    p53 regulates mitochondrial respiration (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-05-27
    Description: The energy that sustains cancer cells is derived preferentially from glycolysis. This metabolic change, the Warburg effect, was one of the first alterations in cancer cells recognized as conferring a survival advantage. Here, we show that p53, one of the most frequently mutated genes in cancers, modulates the balance between the utilization of respiratory and glycolytic pathways. We identify Synthesis of Cytochrome c Oxidase 2 (SCO2) as the downstream mediator of this effect in mice and human cancer cell lines. SCO2 is critical for regulating the cytochrome c oxidase (COX) complex, the major site of oxygen utilization in the eukaryotic cell. Disruption of the SCO2 gene in human cancer cells with wild-type p53 recapitulated the metabolic switch toward glycolysis that is exhibited by p53-deficient cells. That SCO2 couples p53 to mitochondrial respiration provides a possible explanation for the Warburg effect and offers new clues as to how p53 might affect aging and metabolism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matoba, Satoaki -- Kang, Ju-Gyeong -- Patino, Willmar D -- Wragg, Andrew -- Boehm, Manfred -- Gavrilova, Oksana -- Hurley, Paula J -- Bunz, Fred -- Hwang, Paul M -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2006 Jun 16;312(5780):1650-3.

    The nucleosomal surface as a docking station for Kaposi's sarcoma herpesvirus LANA (2006)

    Details
    Publication Date: 2006-02-14
    Description: Kaposi's sarcoma-associated herpesvirus (KSHV) latency-associated nuclear antigen (LANA) mediates viral genome attachment to mitotic chromosomes. We find that N-terminal LANA docks onto chromosomes by binding nucleosomes through the folded region of histones H2A-H2B. The same LANA residues were required for both H2A-H2B binding and chromosome association. Further, LANA did not bind Xenopus sperm chromatin, which is deficient in H2A-H2B; chromatin binding was rescued after assembly of nucleosomes containing H2A-H2B. We also describe the 2.9-angstrom crystal structure of a nucleosome complexed with the first 23 LANA amino acids. The LANA peptide forms a hairpin that interacts exclusively with an acidic H2A-H2B region that is implicated in the formation of higher order chromatin structure. Our findings present a paradigm for how nucleosomes may serve as binding platforms for viral and cellular proteins and reveal a previously unknown mechanism for KSHV latency.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barbera, Andrew J -- Chodaparambil, Jayanth V -- Kelley-Clarke, Brenna -- Joukov, Vladimir -- Walter, Johannes C -- Luger, Karolin -- Kaye, Kenneth M -- CA82036/CA/NCI NIH HHS/ -- GM067777/GM/NIGMS NIH HHS/ -- GM62267/GM/NIGMS NIH HHS/ -- R01 GM067777/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 10;311(5762):856-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Channing Laboratory, Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16469929" target="_blank"〉PubMed〈/a〉

    Large punctuational contribution of speciation to evolutionary divergence at the molecular level (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-10-07
    Description: A long-standing debate in evolutionary biology concerns whether species diverge gradually through time or by punctuational episodes at the time of speciation. We found that approximately 22% of substitutional changes at the DNA level can be attributed to punctuational evolution, and the remainder accumulates from background gradual divergence. Punctuational effects occur at more than twice the rate in plants and fungi than in animals, but the proportion of total divergence attributable to punctuational change does not vary among these groups. Punctuational changes cause departures from a clock-like tempo of evolution, suggesting that they should be accounted for in deriving dates from phylogenies. Punctuational episodes of evolution may play a larger role in promoting evolutionary divergence than has previously been appreciated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pagel, Mark -- Venditti, Chris -- Meade, Andrew -- New York, N.Y. -- Science. 2006 Oct 6;314(5796):119-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biological Sciences, University of Reading, Whiteknights, Reading RG6 6AJ, UK. m.pagel@rdg.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17023657" target="_blank"〉PubMed〈/a〉

    An architectural framework that may lie at the core of the postsynaptic density (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-01-28
    Description: The postsynaptic density (PSD) is a complex assembly of proteins associated with the postsynaptic membrane that organizes neurotransmitter receptors, signaling pathways, and regulatory elements within a cytoskeletal matrix. Here we show that the sterile alpha motif domain of rat Shank3/ProSAP2, a master scaffolding protein located deep within the PSD, can form large sheets composed of helical fibers stacked side by side. Zn2+, which is found in high concentrations in the PSD, binds tightly to Shank3 and may regulate assembly. Sheets of the Shank protein could form a platform for the construction of the PSD complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baron, Marisa K -- Boeckers, Tobias M -- Vaida, Bianca -- Faham, Salem -- Gingery, Mari -- Sawaya, Michael R -- Salyer, Danielle -- Gundelfinger, Eckart D -- Bowie, James U -- R01 CA081000/CA/NCI NIH HHS/ -- R01 GM063919/GM/NIGMS NIH HHS/ -- R01 GM063919-07/GM/NIGMS NIH HHS/ -- R01 GM063919-08/GM/NIGMS NIH HHS/ -- R01 GM075922/GM/NIGMS NIH HHS/ -- R01 GM075922-04/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Jan 27;311(5760):531-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, Molecular Biology Institute, University of California, Los Angeles, 611 Charles E.

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-14
    Description: Plants may "eavesdrop" on volatile organic compounds (VOCs) released by herbivore-attacked neighbors to activate defenses before being attacked themselves. Transcriptome and signal cascade analyses of VOC-exposed plants suggest that plants eavesdrop to prime direct and indirect defenses and to hone competitive abilities. Advances in research on VOC biosynthesis and perception have facilitated the production of plants that are genetically "deaf" to particular VOCs or "mute" in elements of their volatile vocabulary. Such plants, together with advances in VOC analytical instrumentation, will allow researchers to determine whether fluency enhances the fitness of plants in natural communities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baldwin, Ian T -- Halitschke, Rayko -- Paschold, Anja -- von Dahl, Caroline C -- Preston, Catherine A -- New York, N.Y. -- Science. 2006 Feb 10;311(5762):812-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Ecology, Max Planck Institute for Chemical Ecology, Hans Knoll Strasse 8, Jena 07745, Germany. baldwin@ice.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16469918" target="_blank"〉PubMed〈/a〉

    Targeting tyrosine kinases in cancer: the second wave (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-05-27
    Description: One of the most exciting developments in cancer research in recent years has been the clinical validation of molecularly targeted drugs that inhibit the action of pathogenic tyrosine kinases. Treatment of appropriately selected patients with these drugs can alter the natural history of their disease and improve survival. The clinical validation of these "first-generation" tyrosine kinase inhibitors has been the prelude to a second wave of advances in molecular targeting that is expected to further change the way we classify and treat cancer. Efforts are now being directed at identifying the tumor subtypes and patients who will benefit the most from these drugs. In addition, new compounds that circumvent acquired resistance to the first-generation tyrosine kinase inhibitors are being tested in patients with refractory disease. Agents directed against new molecular targets are also being explored.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baselga, Jose -- New York, N.Y. -- Science. 2006 May 26;312(5777):1175-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Oncology Program, Vall d'Hebron University Hospital and Vall d'Hebron Research Institute, Universidad Autonoma de Barcelona, Barcelona 08035, Spain. jbaselga@vhebron.net〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16728632" target="_blank"〉PubMed〈/a〉

    The FERONIA receptor-like kinase mediates male-female interactions during pollen tube reception (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-08-04
    Description: In flowering plants, signaling between the male pollen tube and the synergid cells of the female gametophyte is required for fertilization. In the Arabidopsis thaliana mutant feronia (fer), fertilization is impaired; the pollen tube fails to arrest and thus continues to grow inside the female gametophyte. FER encodes a synergid-expressed, plasma membrane-localized receptor-like kinase. We found that the FER protein accumulates asymmetrically in the synergid membrane at the filiform apparatus. Interspecific crosses using pollen from Arabidopsis lyrata and Cardamine flexuosa on A. thaliana stigmas resulted in a fer-like phenotype that correlates with sequence divergence in the extracellular domain of FER. Our findings show that the female control of pollen tube reception is based on a FER-dependent signaling pathway, which may play a role in reproductive isolation barriers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Escobar-Restrepo, Juan-Miguel -- Huck, Norbert -- Kessler, Sharon -- Gagliardini, Valeria -- Gheyselinck, Jacqueline -- Yang, Wei-Cai -- Grossniklaus, Ueli -- New York, N.Y. -- Science. 2007 Aug 3;317(5838):656-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Plant Biology and Zurich-Basel Plant Science Center, University of Zurich, Zollikerstrasse 107, CH-8008 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17673660" target="_blank"〉PubMed〈/a〉

    Activity-dependent regulation of MEF2 transcription factors suppresses excitatory synapse number (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-18
    Description: In the mammalian nervous system, neuronal activity regulates the strength and number of synapses formed. The genetic program that coordinates this process is poorly understood. We show that myocyte enhancer factor 2 (MEF2) transcription factors suppressed excitatory synapse number in a neuronal activity- and calcineurin-dependent manner as hippocampal neurons formed synapses. In response to increased neuronal activity, calcium influx into neurons induced the activation of the calcium/calmodulin-regulated phosphatase calcineurin, which dephosphorylated and activated MEF2. When activated, MEF2 promoted the transcription of a set of genes, including arc and synGAP, that restrict synapse number. These findings define an activity-dependent transcriptional program that may control synapse number during development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Flavell, Steven W -- Cowan, Christopher W -- Kim, Tae-Kyung -- Greer, Paul L -- Lin, Yingxi -- Paradis, Suzanne -- Griffith, Eric C -- Hu, Linda S -- Chen, Chinfei -- Greenberg, Michael E -- AG05870/AG/NIA NIH HHS/ -- HD18655/HD/NICHD NIH HHS/ -- NS28829/NS/NINDS NIH HHS/ -- R01 EY013613/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 17;311(5763):1008-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neurobiology Program, Children's Hospital, and Departments of Neurology and Neurobiology, Harvard Medical School, 300 Longwood Avenue, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16484497" target="_blank"〉PubMed〈/a〉

    Protein dynamics control the kinetics of initial electron transfer in photosynthesis (2007)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 2007-05-05
    Description: The initial electron transfer dynamics during photosynthesis have been studied in Rhodobacter sphaeroides reaction centers from wild type and 14 mutants in which the driving force and the kinetics of charge separation vary over a broad range. Surprisingly, the protein relaxation kinetics, as measured by tryptophan absorbance changes, are invariant in these mutants. By applying a reaction-diffusion model, we can fit the complex electron transfer kinetics of each mutant quantitatively, varying only the driving force. These results indicate that initial photosynthetic charge separation is limited by protein dynamics rather than by a static electron transfer barrier.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Haiyu -- Lin, Su -- Allen, James P -- Williams, Joann C -- Blankert, Sean -- Laser, Christa -- Woodbury, Neal W -- New York, N.Y. -- Science. 2007 May 4;316(5825):747-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biodesign Institute, Arizona State University, 1001 South McAllister Avenue, Tempe, AZ 85287-5201, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17478721" target="_blank"〉PubMed〈/a〉
