    Central cell-derived peptides regulate early embryo patterning in flowering plants (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-04-12
    Description: Plant embryogenesis initiates with the establishment of an apical-basal axis; however, the molecular mechanisms accompanying this early event remain unclear. Here, we show that a small cysteine-rich peptide family is required for formation of the zygotic basal cell lineage and proembryo patterning in Arabidopsis. EMBRYO SURROUNDING FACTOR 1 (ESF1) peptides accumulate before fertilization in central cell gametes and thereafter in embryo-surrounding endosperm cells. Biochemical and structural analyses revealed cleavage of ESF1 propeptides to form biologically active mature peptides. Further, these peptides act in a non-cell-autonomous manner and synergistically with the receptor-like kinase SHORT SUSPENSOR to promote suspensor elongation through the YODA mitogen-activated protein kinase pathway. Our findings demonstrate that the second female gamete and its sexually derived endosperm regulate early embryonic patterning in flowering plants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Costa, Liliana M -- Marshall, Eleanor -- Tesfaye, Mesfin -- Silverstein, Kevin A T -- Mori, Masashi -- Umetsu, Yoshitaka -- Otterbach, Sophie L -- Papareddy, Ranjith -- Dickinson, Hugh G -- Boutiller, Kim -- VandenBosch, Kathryn A -- Ohki, Shinya -- Gutierrez-Marcos, Jose F -- BB/F008082/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/L003023/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/L003023/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Apr 11;344(6180):168-72. doi: 10.1126/science.1243005.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Sciences, University of Oxford, South Parks Road, OX1 3RB, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24723605" target="_blank"〉PubMed〈/a〉

    Conversion of channelrhodopsin into a light-gated chloride channel (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-03-29
    Description: The field of optogenetics uses channelrhodopsins (ChRs) for light-induced neuronal activation. However, optimized tools for cellular inhibition at moderate light levels are lacking. We found that replacement of E90 in the central gate of ChR with positively charged residues produces chloride-conducting ChRs (ChloCs) with only negligible cation conductance. Molecular dynamics modeling unveiled that a high-affinity Cl(-)-binding site had been generated near the gate. Stabilizing the open state dramatically increased the operational light sensitivity of expressing cells (slow ChloC). In CA1 pyramidal cells, ChloCs completely inhibited action potentials triggered by depolarizing current injections or synaptic stimulation. Thus, by inverting the charge of the selectivity filter, we have created a class of directly light-gated anion channels that can be used to block neuronal output in a fully reversible fashion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wietek, Jonas -- Wiegert, J Simon -- Adeishvili, Nona -- Schneider, Franziska -- Watanabe, Hiroshi -- Tsunoda, Satoshi P -- Vogt, Arend -- Elstner, Marcus -- Oertner, Thomas G -- Hegemann, Peter -- New York, N.Y. -- Science. 2014 Apr 25;344(6182):409-12. doi: 10.1126/science.1249375.

    Enzyme regulation. IRBIT is a novel regulator of ribonucleotide reductase in higher eukaryotes (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-09-23
    Description: Ribonucleotide reductase (RNR) supplies the balanced pools of deoxynucleotide triphosphates (dNTPs) necessary for DNA replication and maintenance of genomic integrity. RNR is subject to allosteric regulatory mechanisms in all eukaryotes, as well as to control by small protein inhibitors Sml1p and Spd1p in budding and fission yeast, respectively. Here, we show that the metazoan protein IRBIT forms a deoxyadenosine triphosphate (dATP)-dependent complex with RNR, which stabilizes dATP in the activity site of RNR and thus inhibits the enzyme. Formation of the RNR-IRBIT complex is regulated through phosphorylation of IRBIT, and ablation of IRBIT expression in HeLa cells causes imbalanced dNTP pools and altered cell cycle progression. We demonstrate a mechanism for RNR regulation in higher eukaryotes that acts by enhancing allosteric RNR inhibition by dATP.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arnaoutov, Alexei -- Dasso, Mary -- New York, N.Y. -- Science. 2014 Sep 19;345(6203):1512-5. doi: 10.1126/science.1251550.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Gene Regulation and Development, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD 20892, USA. arnaouta@mail.nih.gov. ; Laboratory of Gene Regulation and Development, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25237103" target="_blank"〉PubMed〈/a〉

    Structure-guided transformation of channelrhodopsin into a light-activated chloride channel (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-04-26
    Description: Using light to silence electrical activity in targeted cells is a major goal of optogenetics. Available optogenetic proteins that directly move ions to achieve silencing are inefficient, pumping only a single ion per photon across the cell membrane rather than allowing many ions per photon to flow through a channel pore. Building on high-resolution crystal-structure analysis, pore vestibule modeling, and structure-guided protein engineering, we designed and characterized a class of channelrhodopsins (originally cation-conducting) converted into chloride-conducting anion channels. These tools enable fast optical inhibition of action potentials and can be engineered to display step-function kinetics for stable inhibition, outlasting light pulses and for orders-of-magnitude-greater light sensitivity of inhibited cells. The resulting family of proteins defines an approach to more physiological, efficient, and sensitive optogenetic inhibition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4096039/" 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/PMC4096039/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berndt, Andre -- Lee, Soo Yeun -- Ramakrishnan, Charu -- Deisseroth, Karl -- R01 DA020794/DA/NIDA NIH HHS/ -- R01 MH075957/MH/NIMH NIH HHS/ -- R01 MH086373/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Apr 25;344(6182):420-4. doi: 10.1126/science.1252367.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bioengineering, Stanford University, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24763591" target="_blank"〉PubMed〈/a〉

    Structure of a class C GPCR metabotropic glutamate receptor 1 bound to an allosteric modulator (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-03-08
    Description: The excitatory neurotransmitter glutamate induces modulatory actions via the metabotropic glutamate receptors (mGlus), which are class C G protein-coupled receptors (GPCRs). We determined the structure of the human mGlu1 receptor seven-transmembrane (7TM) domain bound to a negative allosteric modulator, FITM, at a resolution of 2.8 angstroms. The modulator binding site partially overlaps with the orthosteric binding sites of class A GPCRs but is more restricted than most other GPCRs. We observed a parallel 7TM dimer mediated by cholesterols, which suggests that signaling initiated by glutamate's interaction with the extracellular domain might be mediated via 7TM interactions within the full-length receptor dimer. A combination of crystallography, structure-activity relationships, mutagenesis, and full-length dimer modeling provides insights about the allosteric modulation and activation mechanism of class C GPCRs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3991565/" 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/PMC3991565/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Huixian -- Wang, Chong -- Gregory, Karen J -- Han, Gye Won -- Cho, Hyekyung P -- Xia, Yan -- Niswender, Colleen M -- Katritch, Vsevolod -- Meiler, Jens -- Cherezov, Vadim -- Conn, P Jeffrey -- Stevens, Raymond C -- P50 GM073197/GM/NIGMS NIH HHS/ -- R01 DK097376/DK/NIDDK NIH HHS/ -- R01 GM080403/GM/NIGMS NIH HHS/ -- R01 GM099842/GM/NIGMS NIH HHS/ -- R01 MH062646/MH/NIMH NIH HHS/ -- R01 MH090192/MH/NIMH NIH HHS/ -- R01 NS031373/NS/NINDS NIH HHS/ -- R21 NS078262/NS/NINDS NIH HHS/ -- R37 NS031373/NS/NINDS NIH HHS/ -- U54 GM094618/GM/NIGMS NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Apr 4;344(6179):58-64. doi: 10.1126/science.1249489.

    Contribution of NAC transcription factors to plant adaptation to land (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-03-22
    Description: The development of cells specialized for water conduction or support is a striking innovation of plants that has enabled them to colonize land. The NAC transcription factors regulate the differentiation of these cells in vascular plants. However, the path by which plants with these cells have evolved from their nonvascular ancestors is unclear. We investigated genes of the moss Physcomitrella patens that encode NAC proteins. Loss-of-function mutants formed abnormal water-conducting and supporting cells, as well as malformed sporophyte cells, and overexpression induced ectopic differentiation of water-conducting-like cells. Our results show conservation of transcriptional regulation and cellular function between moss and Arabidopsis thaliana water-conducting cells. The conserved genetic basis suggests roles for NAC proteins in the adaptation of plants to land.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xu, Bo -- Ohtani, Misato -- Yamaguchi, Masatoshi -- Toyooka, Kiminori -- Wakazaki, Mayumi -- Sato, Mayuko -- Kubo, Minoru -- Nakano, Yoshimi -- Sano, Ryosuke -- Hiwatashi, Yuji -- Murata, Takashi -- Kurata, Tetsuya -- Yoneda, Arata -- Kato, Ko -- Hasebe, Mitsuyasu -- Demura, Taku -- New York, N.Y. -- Science. 2014 Mar 28;343(6178):1505-8. doi: 10.1126/science.1248417.

    Sensory biology. Evolution of sweet taste perception in hummingbirds by transformation of the ancestral umami receptor (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-08-26
    Description: Sensory systems define an animal's capacity for perception and can evolve to promote survival in new environmental niches. We have uncovered a noncanonical mechanism for sweet taste perception that evolved in hummingbirds since their divergence from insectivorous swifts, their closest relatives. We observed the widespread absence in birds of an essential subunit (T1R2) of the only known vertebrate sweet receptor, raising questions about how specialized nectar feeders such as hummingbirds sense sugars. Receptor expression studies revealed that the ancestral umami receptor (the T1R1-T1R3 heterodimer) was repurposed in hummingbirds to function as a carbohydrate receptor. Furthermore, the molecular recognition properties of T1R1-T1R3 guided taste behavior in captive and wild hummingbirds. We propose that changing taste receptor function enabled hummingbirds to perceive and use nectar, facilitating the massive radiation of hummingbird species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4302410/" 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/PMC4302410/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baldwin, Maude W -- Toda, Yasuka -- Nakagita, Tomoya -- O'Connell, Mary J -- Klasing, Kirk C -- Misaka, Takumi -- Edwards, Scott V -- Liberles, Stephen D -- R01 DC013289/DC/NIDCD NIH HHS/ -- R01DC013289/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 2014 Aug 22;345(6199):929-33. doi: 10.1126/science.1255097.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Organismic and Evolutionary Biology, Harvard University, and Museum of Comparative Zoology, Cambridge, MA 02138, USA. maudebaldwin@gmail.com stephen_liberles@hms.harvard.edu. ; Department of Applied Biological Chemistry, Graduate School of Agricultural and Life Sciences, University of Tokyo, 1-1-1 Yayoi, Bunkyo-ku, Tokyo, Japan. ; Bioinformatics and Molecular Evolution Group, School of Biotechnology, Dublin City University, Glasnevin, Dublin 9, Ireland. ; Department of Animal Science, University of California, Davis, Davis, CA 95616, USA. ; Department of Organismic and Evolutionary Biology, Harvard University, and Museum of Comparative Zoology, Cambridge, MA 02138, USA. ; Department of Cell Biology, Harvard Medical School, Boston, MA 02115, USA. maudebaldwin@gmail.com stephen_liberles@hms.harvard.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25146290" target="_blank"〉PubMed〈/a〉

    Cryo-EM study of the chromatin fiber reveals a double helix twisted by tetranucleosomal units (2014)

    Publication Date: 2014-04-26
    Description: The hierarchical packaging of eukaryotic chromatin plays a central role in transcriptional regulation and other DNA-related biological processes. Here, we report the 11-angstrom-resolution cryogenic electron microscopy (cryo-EM) structures of 30-nanometer chromatin fibers reconstituted in the presence of linker histone H1 and with different nucleosome repeat lengths. The structures show a histone H1-dependent left-handed twist of the repeating tetranucleosomal structural units, within which the four nucleosomes zigzag back and forth with a straight linker DNA. The asymmetric binding and the location of histone H1 in chromatin play a role in the formation of the 30-nanometer fiber. Our results provide mechanistic insights into how nucleosomes compact into higher-order chromatin fibers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Song, Feng -- Chen, Ping -- Sun, Dapeng -- Wang, Mingzhu -- Dong, Liping -- Liang, Dan -- Xu, Rui-Ming -- Zhu, Ping -- Li, Guohong -- New York, N.Y. -- Science. 2014 Apr 25;344(6182):376-80. doi: 10.1126/science.1251413.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Laboratory of Biomacromolecules, Institute of Biophysics, Chinese Academy of Sciences, Beijing 100101, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24763583" target="_blank"〉PubMed〈/a〉

    Perception of root-derived peptides by shoot LRR-RKs mediates systemic N-demand signaling (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-10-18
    Description: Nitrogen (N) is a critical nutrient for plants but is often distributed unevenly in the soil. Plants therefore have evolved a systemic mechanism by which N starvation on one side of the root system leads to a compensatory and increased nitrate uptake on the other side. Here, we study the molecular systems that support perception of N and the long-distance signaling needed to alter root development. Rootlets starved of N secrete small peptides that are translocated to the shoot and received by two leucine-rich repeat receptor kinases (LRR-RKs). Arabidopsis plants deficient in this pathway show growth retardation accompanied with N-deficiency symptoms. Thus, signaling from the root to the shoot helps the plant adapt to fluctuations in local N availability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tabata, Ryo -- Sumida, Kumiko -- Yoshii, Tomoaki -- Ohyama, Kentaro -- Shinohara, Hidefumi -- Matsubayashi, Yoshikatsu -- New York, N.Y. -- Science. 2014 Oct 17;346(6207):343-6. doi: 10.1126/science.1257800.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biological Science, Graduate School of Science, Nagoya University, Chikusa, Nagoya 464-8602, Japan. ; Department of Applied Molecular Biosciences, Graduate School of Bio-Agricultural Sciences, Nagoya University, Chikusa, Nagoya 464-8601, Japan. ; Division of Biological Science, Graduate School of Science, Nagoya University, Chikusa, Nagoya 464-8602, Japan. matsu@bio.nagoya-u.ac.jp.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25324386" target="_blank"〉PubMed〈/a〉

    Mechanism of actin filament pointed-end capping by tropomodulin (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-07-26
    Description: Proteins that cap the ends of the actin filament are essential regulators of cytoskeleton dynamics. Whereas several proteins cap the rapidly growing barbed end, tropomodulin (Tmod) is the only protein known to cap the slowly growing pointed end. The lack of structural information severely limits our understanding of Tmod's capping mechanism. We describe crystal structures of actin complexes with the unstructured amino-terminal and the leucine-rich repeat carboxy-terminal domains of Tmod. The structures and biochemical analysis of structure-inspired mutants showed that one Tmod molecule interacts with three actin subunits at the pointed end, while also contacting two tropomyosin molecules on each side of the filament. We found that Tmod achieves high-affinity binding through several discrete low-affinity interactions, which suggests a mechanism for controlled subunit exchange at the pointed end.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4367809/" 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/PMC4367809/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rao, Jampani Nageswara -- Madasu, Yadaiah -- Dominguez, Roberto -- GM-0080/GM/NIGMS NIH HHS/ -- R01 GM073791/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Jul 25;345(6195):463-7. doi: 10.1126/science.1256159.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104, USA. ; Department of Physiology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104, USA. droberto@mail.med.upenn.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25061212" target="_blank"〉PubMed〈/a〉

    Description: This Review presents basic facts regarding the long-run evolution of income and wealth inequality in Europe and the United States. Income and wealth inequality was very high a century ago, particularly in Europe, but dropped dramatically in the first half of the 20th century. Income inequality has surged back in the United States since the 1970s so that the United States is much more unequal than Europe today. We discuss possible interpretations and lessons for the future.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Piketty, Thomas -- Saez, Emmanuel -- New York, N.Y. -- Science. 2014 May 23;344(6186):838-43. doi: 10.1126/science.1251936.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Economics, Paris School of Economics, Paris, France. thomas.piketty@psemail.eu. ; Department of Economics, University of California at Berkeley, Berkeley, CA, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24855258" target="_blank"〉PubMed〈/a〉

    A promiscuous intermediate underlies the evolution of LEAFY DNA binding specificity (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-01-18
    Description: Transcription factors (TFs) are key players in evolution. Changes affecting their function can yield novel life forms but may also have deleterious effects. Consequently, gene duplication events that release one gene copy from selective pressure are thought to be the common mechanism by which TFs acquire new activities. Here, we show that LEAFY, a major regulator of flower development and cell division in land plants, underwent changes to its DNA binding specificity, even though plant genomes generally contain a single copy of the LEAFY gene. We examined how these changes occurred at the structural level and identify an intermediate LEAFY form in hornworts that appears to adopt all different specificities. This promiscuous intermediate could have smoothed the evolutionary transitions, thereby allowing LEAFY to evolve new binding specificities while remaining a single-copy gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sayou, Camille -- Monniaux, Marie -- Nanao, Max H -- Moyroud, Edwige -- Brockington, Samuel F -- Thevenon, Emmanuel -- Chahtane, Hicham -- Warthmann, Norman -- Melkonian, Michael -- Zhang, Yong -- Wong, Gane Ka-Shu -- Weigel, Detlef -- Parcy, Francois -- Dumas, Renaud -- New York, N.Y. -- Science. 2014 Feb 7;343(6171):645-8. doi: 10.1126/science.1248229.

    Climate change. Projected increase in lightning strikes in the United States due to global warming (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-11-15
    Description: Lightning plays an important role in atmospheric chemistry and in the initiation of wildfires, but the impact of global warming on lightning rates is poorly constrained. Here we propose that the lightning flash rate is proportional to the convective available potential energy (CAPE) times the precipitation rate. Using observations, the product of CAPE and precipitation explains 77% of the variance in the time series of total cloud-to-ground lightning flashes over the contiguous United States (CONUS). Storms convert CAPE times precipitated water mass to discharged lightning energy with an efficiency of 1%. When this proxy is applied to 11 climate models, CONUS lightning strikes are predicted to increase 12 +/- 5% per degree Celsius of global warming and about 50% over this century.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Romps, David M -- Seeley, Jacob T -- Vollaro, David -- Molinari, John -- New York, N.Y. -- Science. 2014 Nov 14;346(6211):851-4. doi: 10.1126/science.1259100.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Planetary Science, University of California, Berkeley, and Earth Sciences Division, Lawrence Berkeley National Laboratory, Berkeley, CA, USA. romps@berkeley.edu. ; Department of Earth and Planetary Science, University of California, Berkeley, and Earth Sciences Division, Lawrence Berkeley National Laboratory, Berkeley, CA, USA. ; Department of Atmospheric and Environmental Sciences, State University of New York at Albany, Albany, NY, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25395536" target="_blank"〉PubMed〈/a〉

    HIV transmission. Selection bias at the heterosexual HIV-1 transmission bottleneck (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-07-12
    Description: Heterosexual transmission of HIV-1 typically results in one genetic variant establishing systemic infection. We compared, for 137 linked transmission pairs, the amino acid sequences encoded by non-envelope genes of viruses in both partners and demonstrate a selection bias for transmission of residues that are predicted to confer increased in vivo fitness on viruses in the newly infected, immunologically naive recipient. Although tempered by transmission risk factors, such as donor viral load, genital inflammation, and recipient gender, this selection bias provides an overall transmission advantage for viral quasispecies that are dominated by viruses with high in vivo fitness. Thus, preventative or therapeutic approaches that even marginally reduce viral fitness may lower the overall transmission rates and offer long-term benefits even upon successful transmission.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4289910/" 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/PMC4289910/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carlson, Jonathan M -- Schaefer, Malinda -- Monaco, Daniela C -- Batorsky, Rebecca -- Claiborne, Daniel T -- Prince, Jessica -- Deymier, Martin J -- Ende, Zachary S -- Klatt, Nichole R -- DeZiel, Charles E -- Lin, Tien-Ho -- Peng, Jian -- Seese, Aaron M -- Shapiro, Roger -- Frater, John -- Ndung'u, Thumbi -- Tang, Jianming -- Goepfert, Paul -- Gilmour, Jill -- Price, Matt A -- Kilembe, William -- Heckerman, David -- Goulder, Philip J R -- Allen, Todd M -- Allen, Susan -- Hunter, Eric -- 2P51RR000165-51/RR/NCRR NIH HHS/ -- G108/626/Medical Research Council/United Kingdom -- OD P51OD11132/OD/NIH HHS/ -- P01-AI074415/AI/NIAID NIH HHS/ -- P30 AI050409/AI/NIAID NIH HHS/ -- P51 OD010425/OD/NIH HHS/ -- P51 OD011132/OD/NIH HHS/ -- P51RR165/RR/NCRR NIH HHS/ -- R01 AI064060/AI/NIAID NIH HHS/ -- R01 AI64060/AI/NIAID NIH HHS/ -- R37 AI051231/AI/NIAID NIH HHS/ -- R37 AI51231/AI/NIAID NIH HHS/ -- T32 AI007387/AI/NIAID NIH HHS/ -- T32-AI007387/AI/NIAID NIH HHS/ -- U01 AI 66454/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Jul 11;345(6193):1254031. doi: 10.1126/science.1254031.

    Optical control of muscle function by transplantation of stem cell-derived motor neurons in mice (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-04-05
    Description: Damage to the central nervous system caused by traumatic injury or neurological disorders can lead to permanent loss of voluntary motor function and muscle paralysis. Here, we describe an approach that circumvents central motor circuit pathology to restore specific skeletal muscle function. We generated murine embryonic stem cell-derived motor neurons that express the light-sensitive ion channel channelrhodopsin-2, which we then engrafted into partially denervated branches of the sciatic nerve of adult mice. These engrafted motor neurons not only reinnervated lower hind-limb muscles but also enabled their function to be restored in a controllable manner using optogenetic stimulation. This synthesis of regenerative medicine and optogenetics may be a successful strategy to restore muscle function after traumatic injury or disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bryson, J Barney -- Machado, Carolina Barcellos -- Crossley, Martin -- Stevenson, Danielle -- Bros-Facer, Virginie -- Burrone, Juan -- Greensmith, Linda -- Lieberam, Ivo -- 095589/Wellcome Trust/United Kingdom -- G0900585/Medical Research Council/United Kingdom -- G1001234/Biotechnology and Biological Sciences Research Council/United Kingdom -- MR/K000608/1/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2014 Apr 4;344(6179):94-7. doi: 10.1126/science.1248523.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sobell Department of Motor Neuroscience and Movement Disorders, University College London (UCL) Institute of Neurology, London, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24700859" target="_blank"〉PubMed〈/a〉

    Characterization of a DNA exit gate in the human cohesin ring (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-11-22
    Description: Chromosome segregation depends on sister chromatid cohesion mediated by cohesin. The cohesin subunits Smc1, Smc3, and Scc1 form tripartite rings that are thought to open at distinct sites to allow entry and exit of DNA. However, direct evidence for the existence of open forms of cohesin is lacking. We found that cohesin's proposed DNA exit gate is formed by interactions between Scc1 and the coiled-coil region of Smc3. Mutation of this interface abolished cohesin's ability to stably associate with chromatin and to mediate cohesion. Electron microscopy revealed that weakening of the Smc3-Scc1 interface resulted in opening of cohesin rings, as did proteolytic cleavage of Scc1.

    Structures of PI4KIIIbeta complexes show simultaneous recruitment of Rab11 and its effectors (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-05-31
    Description: Phosphatidylinositol 4-kinases (PI4Ks) and small guanosine triphosphatases (GTPases) are essential for processes that require expansion and remodeling of phosphatidylinositol 4-phosphate (PI4P)-containing membranes, including cytokinesis, intracellular development of malarial pathogens, and replication of a wide range of RNA viruses. However, the structural basis for coordination of PI4K, GTPases, and their effectors is unknown. Here, we describe structures of PI4Kbeta (PI4KIIIbeta) bound to the small GTPase Rab11a without and with the Rab11 effector protein FIP3. The Rab11-PI4KIIIbeta interface is distinct compared with known structures of Rab complexes and does not involve switch regions used by GTPase effectors. Our data provide a mechanism for how PI4KIIIbeta coordinates Rab11 and its effectors on PI4P-enriched membranes and also provide strategies for the design of specific inhibitors that could potentially target plasmodial PI4KIIIbeta to combat malaria.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4046302/" 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/PMC4046302/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burke, John E -- Inglis, Alison J -- Perisic, Olga -- Masson, Glenn R -- McLaughlin, Stephen H -- Rutaganira, Florentine -- Shokat, Kevan M -- Williams, Roger L -- MC_U105184308/Medical Research Council/United Kingdom -- PG/11/109/29247/British Heart Foundation/United Kingdom -- PG11/109/29247/British Heart Foundation/United Kingdom -- R01AI099245/AI/NIAID NIH HHS/ -- T32 GM064337/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 May 30;344(6187):1035-8. doi: 10.1126/science.1253397.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council (MRC) Laboratory of Molecular Biology, Cambridge CB2 0QH, UK. jeburke@uvic.ca rlw@mrc-lmb.cam.ac.uk. ; Medical Research Council (MRC) Laboratory of Molecular Biology, Cambridge CB2 0QH, UK. ; Howard Hughes Medical Institute and Department of Cellular and Molecular Pharmacology, University of California, San Francisco (UCSF), San Francisco, CA 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24876499" target="_blank"〉PubMed〈/a〉

    Toddler: an embryonic signal that promotes cell movement via Apelin receptors (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-01-11
    Description: It has been assumed that most, if not all, signals regulating early development have been identified. Contrary to this expectation, we identified 28 candidate signaling proteins expressed during zebrafish embryogenesis, including Toddler, a short, conserved, and secreted peptide. Both absence and overproduction of Toddler reduce the movement of mesendodermal cells during zebrafish gastrulation. Local and ubiquitous production of Toddler promote cell movement, suggesting that Toddler is neither an attractant nor a repellent but acts globally as a motogen. Toddler drives internalization of G protein-coupled APJ/Apelin receptors, and activation of APJ/Apelin signaling rescues toddler mutants. These results indicate that Toddler is an activator of APJ/Apelin receptor signaling, promotes gastrulation movements, and might be the first in a series of uncharacterized developmental signals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4107353/" 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/PMC4107353/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pauli, Andrea -- Norris, Megan L -- Valen, Eivind -- Chew, Guo-Liang -- Gagnon, James A -- Zimmerman, Steven -- Mitchell, Andrew -- Ma, Jiao -- Dubrulle, Julien -- Reyon, Deepak -- Tsai, Shengdar Q -- Joung, J Keith -- Saghatelian, Alan -- Schier, Alexander F -- K99 HD076935/HD/NICHD NIH HHS/ -- R01 GM056211/GM/NIGMS NIH HHS/ -- R01 GM102491/GM/NIGMS NIH HHS/ -- R01 HG005111/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Feb 14;343(6172):1248636. doi: 10.1126/science.1248636.

    Chemical biology. A bump-and-hole approach to engineer controlled selectivity of BET bromodomain chemical probes (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-10-18
    Description: Small molecules are useful tools for probing the biological function and therapeutic potential of individual proteins, but achieving selectivity is challenging when the target protein shares structural domains with other proteins. The Bromo and Extra-Terminal (BET) proteins have attracted interest because of their roles in transcriptional regulation, epigenetics, and cancer. The BET bromodomains (protein interaction modules that bind acetyl-lysine) have been targeted by potent small-molecule inhibitors, but these inhibitors lack selectivity for individual family members. We developed an ethyl derivative of an existing small-molecule inhibitor, I-BET/JQ1, and showed that it binds leucine/alanine mutant bromodomains with nanomolar affinity and achieves up to 540-fold selectivity relative to wild-type bromodomains. Cell culture studies showed that blockade of the first bromodomain alone is sufficient to displace a specific BET protein, Brd4, from chromatin. Expansion of this approach could help identify the individual roles of single BET proteins in human physiology and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4458378/" 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/PMC4458378/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baud, Matthias G J -- Lin-Shiao, Enrique -- Cardote, Teresa -- Tallant, Cynthia -- Pschibul, Annica -- Chan, Kwok-Ho -- Zengerle, Michael -- Garcia, Jordi R -- Kwan, Terence T-L -- Ferguson, Fleur M -- Ciulli, Alessio -- 097945/Z/11/Z/Wellcome Trust/United Kingdom -- 100476/Z/12/Z/Wellcome Trust/United Kingdom -- BB/G023123/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/J001201/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Oct 31;346(6209):638-41. doi: 10.1126/science.1249830.

    Dynamic reorganization of river basins (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-03-08
    Description: River networks evolve as migrating drainage divides reshape river basins and change network topology by capture of river channels. We demonstrate that a characteristic metric of river network geometry gauges the horizontal motion of drainage divides. Assessing this metric throughout a landscape maps the dynamic states of entire river networks, revealing diverse conditions: Drainage divides in the Loess Plateau of China appear stationary; the young topography of Taiwan has migrating divides driving adjustment of major basins; and rivers draining the ancient landscape of the southeastern United States are reorganizing in response to escarpment retreat and coastal advance. The ability to measure the dynamic reorganization of river basins presents opportunities to examine landscape-scale interactions among tectonics, erosion, and ecology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willett, Sean D -- McCoy, Scott W -- Perron, J Taylor -- Goren, Liran -- Chen, Chia-Yu -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1248765. doi: 10.1126/science.1248765.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Geological Institute, Swiss Federal Institute of Technology, 8092 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24604204" target="_blank"〉PubMed〈/a〉

    Closing the cohesin ring: structure and function of its Smc3-kleisin interface (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-11-22
    Description: Through their association with a kleisin subunit (Scc1), cohesin's Smc1 and Smc3 subunits are thought to form tripartite rings that mediate sister chromatid cohesion. Unlike the structure of Smc1/Smc3 and Smc1/Scc1 interfaces, that of Smc3/Scc1 is not known. Disconnection of this interface is thought to release cohesin from chromosomes in a process regulated by acetylation. We show here that the N-terminal domain of yeast Scc1 contains two alpha helices, forming a four-helix bundle with the coiled coil emerging from Smc3's adenosine triphosphatase head. Mutations affecting this interaction compromise cohesin's association with chromosomes. The interface is far from Smc3 residues, whose acetylation prevents cohesin's dissociation from chromosomes. Cohesin complexes holding chromatids together in vivo do indeed have the configuration of hetero-trimeric rings, and sister DNAs are entrapped within these.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4300515/" 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/PMC4300515/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gligoris, Thomas G -- Scheinost, Johanna C -- Burmann, Frank -- Petela, Naomi -- Chan, Kok-Lung -- Uluocak, Pelin -- Beckouet, Frederic -- Gruber, Stephan -- Nasmyth, Kim -- Lowe, Jan -- 091859/Z/10/Z/Wellcome Trust/United Kingdom -- 095514/Wellcome Trust/United Kingdom -- 095514/Z/11/Z/Wellcome Trust/United Kingdom -- C573/A 12386/Cancer Research UK/United Kingdom -- C573/A11625/Medical Research Council/United Kingdom -- MC_U105184326/Medical Research Council/United Kingdom -- U10518432/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Nov 21;346(6212):963-7. doi: 10.1126/science.1256917.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Oxford, Oxford, OX1 3QU, UK. ; Max-Planck-Institut fur Biochemie, 82152, Martinsried, Germany. ; Department of Biochemistry, University of Oxford, Oxford, OX1 3QU, UK.

    Evolution of oligomeric state through allosteric pathways that mimic ligand binding (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-12-20
    Description: Evolution and design of protein complexes are almost always viewed through the lens of amino acid mutations at protein interfaces. We showed previously that residues not involved in the physical interaction between proteins make important contributions to oligomerization by acting indirectly or allosterically. In this work, we sought to investigate the mechanism by which allosteric mutations act, using the example of the PyrR family of pyrimidine operon attenuators. In this family, a perfectly sequence-conserved helix that forms a tetrameric interface is exposed as solvent-accessible surface in dimeric orthologs. This means that mutations must be acting from a distance to destabilize the interface. We identified 11 key mutations controlling oligomeric state, all distant from the interfaces and outside ligand-binding pockets. Finally, we show that the key mutations introduce conformational changes equivalent to the conformational shift between the free versus nucleotide-bound conformations of the proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4337988/" 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/PMC4337988/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perica, Tina -- Kondo, Yasushi -- Tiwari, Sandhya P -- McLaughlin, Stephen H -- Kemplen, Katherine R -- Zhang, Xiuwei -- Steward, Annette -- Reuter, Nathalie -- Clarke, Jane -- Teichmann, Sarah A -- 095195/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2014 Dec 19;346(6216):1254346. doi: 10.1126/science.1254346.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉European Bioinformatics Institute, Wellcome Trust Genome Campus, Hinxton, Cambridge CB10 1SD, UK.

    Crystal structure of a claudin provides insight into the architecture of tight junctions (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-04-20
    Description: Tight junctions are cell-cell adhesion structures in epithelial cell sheets that surround organ compartments in multicellular organisms and regulate the permeation of ions through the intercellular space. Claudins are the major constituents of tight junctions and form strands that mediate cell adhesion and function as paracellular barriers. We report the structure of mammalian claudin-15 at a resolution of 2.4 angstroms. The structure reveals a characteristic beta-sheet fold comprising two extracellular segments, which is anchored to a transmembrane four-helix bundle by a consensus motif. Our analyses suggest potential paracellular pathways with distinctive charges on the extracellular surface, providing insight into the molecular basis of ion homeostasis across tight junctions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suzuki, Hiroshi -- Nishizawa, Tomohiro -- Tani, Kazutoshi -- Yamazaki, Yuji -- Tamura, Atsushi -- Ishitani, Ryuichiro -- Dohmae, Naoshi -- Tsukita, Sachiko -- Nureki, Osamu -- Fujiyoshi, Yoshinori -- New York, N.Y. -- Science. 2014 Apr 18;344(6181):304-7. doi: 10.1126/science.1248571.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cellular and Structural Physiology Institute, Nagoya University, Chikusa, Nagoya 464-8601, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24744376" target="_blank"〉PubMed〈/a〉

    Transdifferentiation. Sequential histone-modifying activities determine the robustness of transdifferentiation (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-08-16
    Description: Natural interconversions between distinct somatic cell types have been reported in species as diverse as jellyfish and mice. The efficiency and reproducibility of some reprogramming events represent unexploited avenues in which to probe mechanisms that ensure robust cell conversion. We report that a conserved H3K27me3/me2 demethylase, JMJD-3.1, and the H3K4 methyltransferase Set1 complex cooperate to ensure invariant transdifferentiation (Td) of postmitotic Caenorhabditis elegans hindgut cells into motor neurons. At single-cell resolution, robust conversion requires stepwise histone-modifying activities, functionally partitioned into discrete phases of Td through nuclear degradation of JMJD-3.1 and phase-specific interactions with transcription factors that have conserved roles in cell plasticity and terminal fate selection. Our results draw parallels between epigenetic mechanisms underlying robust Td in nature and efficient cell reprogramming in vitro.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zuryn, Steven -- Ahier, Arnaud -- Portoso, Manuela -- White, Esther Redhouse -- Morin, Marie-Charlotte -- Margueron, Raphael -- Jarriault, Sophie -- New York, N.Y. -- Science. 2014 Aug 15;345(6198):826-9. doi: 10.1126/science.1255885.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Development and Stem Cells, Institut de Genetique et de Biologie Moleculaire et Cellulaire, CNRS UMR 7104/INSERM U964, Universite de Strasbourg, 67404 Illkirch CU Strasbourg, France. ; Institut Curie, INSERM U934, CNRS UMR3215, 26, Rue d'Ulm, 75005 Paris, France. ; Department of Development and Stem Cells, Institut de Genetique et de Biologie Moleculaire et Cellulaire, CNRS UMR 7104/INSERM U964, Universite de Strasbourg, 67404 Illkirch CU Strasbourg, France. sophie@igbmc.fr.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25124442" target="_blank"〉PubMed〈/a〉

    Nutritional immunity. Escape from bacterial iron piracy through rapid evolution of transferrin (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-12-17
    Description: Iron sequestration provides an innate defense, termed nutritional immunity, leading pathogens to scavenge iron from hosts. Although the molecular basis of this battle for iron is established, its potential as a force for evolution at host-pathogen interfaces is unknown. We show that the iron transport protein transferrin is engaged in ancient and ongoing evolutionary conflicts with TbpA, a transferrin surface receptor from bacteria. Single substitutions in transferrin at rapidly evolving sites reverse TbpA binding, providing a mechanism to counteract bacterial iron piracy among great apes. Furthermore, the C2 transferrin polymorphism in humans evades TbpA variants from Haemophilus influenzae, revealing a functional basis for standing genetic variation. These findings identify a central role for nutritional immunity in the persistent evolutionary conflicts between primates and bacterial pathogens.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4455941/" 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/PMC4455941/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barber, Matthew F -- Elde, Nels C -- 1F32GM108288/GM/NIGMS NIH HHS/ -- GM090042/GM/NIGMS NIH HHS/ -- R00 GM090042/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1362-6. doi: 10.1126/science.1259329.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Human Genetics, University of Utah School of Medicine, Salt Lake City, UT 84112, USA. ; Department of Human Genetics, University of Utah School of Medicine, Salt Lake City, UT 84112, USA. nelde@genetics.utah.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25504720" target="_blank"〉PubMed〈/a〉

    Medicaid increases emergency-department use: evidence from Oregon's Health Insurance Experiment (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-01-05
    Description: In 2008, Oregon initiated a limited expansion of a Medicaid program for uninsured, low-income adults, drawing names from a waiting list by lottery. This lottery created a rare opportunity to study the effects of Medicaid coverage by using a randomized controlled design. By using the randomization provided by the lottery and emergency-department records from Portland-area hospitals, we studied the emergency department use of about 25,000 lottery participants over about 18 months after the lottery. We found that Medicaid coverage significantly increases overall emergency use by 0.41 visits per person, or 40% relative to an average of 1.02 visits per person in the control group. We found increases in emergency-department visits across a broad range of types of visits, conditions, and subgroups, including increases in visits for conditions that may be most readily treatable in primary care settings.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3955206/" 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/PMC3955206/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taubman, Sarah L -- Allen, Heidi L -- Wright, Bill J -- Baicker, Katherine -- Finkelstein, Amy N -- P30 AG012810/AG/NIA NIH HHS/ -- P30AG012810/AG/NIA NIH HHS/ -- R01 AG034151/AG/NIA NIH HHS/ -- R01AG0345151/AG/NIA NIH HHS/ -- RC2 AG036631/AG/NIA NIH HHS/ -- RC2AGO36631/RC/CCR NIH HHS/ -- New York, N.Y. -- Science. 2014 Jan 17;343(6168):263-8. doi: 10.1126/science.1246183.
