    Baseline map of carbon emissions from deforestation in tropical regions (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-23
    Description: Policies to reduce emissions from deforestation would benefit from clearly derived, spatially explicit, statistically bounded estimates of carbon emissions. Existing efforts derive carbon impacts of land-use change using broad assumptions, unreliable data, or both. We improve on this approach using satellite observations of gross forest cover loss and a map of forest carbon stocks to estimate gross carbon emissions across tropical regions between 2000 and 2005 as 0.81 petagram of carbon per year, with a 90% prediction interval of 0.57 to 1.22 petagrams of carbon per year. This estimate is 25 to 50% of recently published estimates. By systematically matching areas of forest loss with their carbon stocks before clearing, these results serve as a more accurate benchmark for monitoring global progress on reducing emissions from deforestation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harris, Nancy L -- Brown, Sandra -- Hagen, Stephen C -- Saatchi, Sassan S -- Petrova, Silvia -- Salas, William -- Hansen, Matthew C -- Potapov, Peter V -- Lotsch, Alexander -- New York, N.Y. -- Science. 2012 Jun 22;336(6088):1573-6. doi: 10.1126/science.1217962.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ecosystem Services Unit, Winrock International, Arlington, VA 22202, USA. nharris@winrock.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22723420" target="_blank"〉PubMed〈/a〉

    Printing and prototyping of tissues and scaffolds (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-11-20
    Description: New manufacturing technologies under the banner of rapid prototyping enable the fabrication of structures close in architecture to biological tissue. In their simplest form, these technologies allow the manufacture of scaffolds upon which cells can grow for later implantation into the body. A more exciting prospect is the printing and patterning in three dimensions of all the components that make up a tissue (cells and matrix materials) to generate structures analogous to tissues; this has been termed bioprinting. Such techniques have opened new areas of research in tissue engineering and regenerative medicine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Derby, Brian -- New York, N.Y. -- Science. 2012 Nov 16;338(6109):921-6. doi: 10.1126/science.1226340.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Materials, University of Manchester, Oxford Road, Manchester M13 9PL, UK. brian.derby@manchester.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23161993" target="_blank"〉PubMed〈/a〉

    Rocket launcher mechanism of collaborative actin assembly defined by single-molecule imaging (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-02
    Description: Interacting sets of actin assembly factors work together in cells, but the underlying mechanisms have remained obscure. We used triple-color single-molecule fluorescence microscopy to image the tumor suppressor adenomatous polyposis coli (APC) and the formin mDia1 during filament assembly. Complexes consisting of APC, mDia1, and actin monomers initiated actin filament formation, overcoming inhibition by capping protein and profilin. Upon filament polymerization, the complexes separated, with mDia1 moving processively on growing barbed ends while APC remained at the site of nucleation. Thus, the two assembly factors directly interact to initiate filament assembly and then separate but retain independent associations with either end of the growing filament.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3613992/" 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/PMC3613992/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Breitsprecher, Dennis -- Jaiswal, Richa -- Bombardier, Jeffrey P -- Gould, Christopher J -- Gelles, Jeff -- Goode, Bruce L -- GM083137/GM/NIGMS NIH HHS/ -- GM43369/GM/NIGMS NIH HHS/ -- GM81648/GM/NIGMS NIH HHS/ -- R01 GM063691/GM/NIGMS NIH HHS/ -- R01 GM081648/GM/NIGMS NIH HHS/ -- R01 GM083137/GM/NIGMS NIH HHS/ -- R01 GM098143/GM/NIGMS NIH HHS/ -- R37 GM043369/GM/NIGMS NIH HHS/ -- T32 EB009419/EB/NIBIB NIH HHS/ -- T32 GM007596/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Jun 1;336(6085):1164-8. doi: 10.1126/science.1218062.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Brandeis University, Waltham, MA 02454, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22654058" target="_blank"〉PubMed〈/a〉

    Natural enemies drive geographic variation in plant defenses (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-10-09
    Description: Plants defend themselves against attack by natural enemies, and these defenses vary widely across populations. However, whether communities of natural enemies are a sufficiently potent force to maintain polymorphisms in defensive traits is largely unknown. Here, we exploit the genetic resources of Arabidopsis thaliana, coupled with 39 years of field data on aphid abundance, to (i) demonstrate that geographic patterns in a polymorphic defense locus (GS-ELONG) are strongly correlated with changes in the relative abundance of two specialist aphids; and (ii) demonstrate differential selection by the two aphids on GS-ELONG, using a multigeneration selection experiment. We thereby show a causal link between variation in abundance of the two specialist aphids and the geographic pattern at GS-ELONG, which highlights the potency of natural enemies as selective forces.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zust, Tobias -- Heichinger, Christian -- Grossniklaus, Ueli -- Harrington, Richard -- Kliebenstein, Daniel J -- Turnbull, Lindsay A -- Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2012 Oct 5;338(6103):116-9. doi: 10.1126/science.1226397.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Evolutionary Biology and Environmental Studies and Zurich-Basel Plant Science Center, University of Zurich, Zurich CH-8057, Switzerland. tobias.zuest@cornell.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23042895" target="_blank"〉PubMed〈/a〉

    Mice lacking a Myc enhancer that includes human SNP rs6983267 are resistant to intestinal tumors (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-11-03
    Description: Multiple cancer-associated single-nucleotide polymorphisms (SNPs) have been mapped to conserved sequences within a 500-kilobase region upstream of the MYC oncogene on human chromosome 8q24. These SNPs may affect cancer development through altered regulation of MYC expression, but this hypothesis has been difficult to confirm. We generated mice deficient in Myc-335, a putative MYC regulatory element that contains rs6983267, a SNP accounting for more human cancer-related morbidity than any other genetic variant or mutation. In Myc-335 null mice, Myc transcripts were expressed in the intestinal crypts in a pattern similar to that in wild-type mice but at modestly reduced levels. The mutant mice displayed no overt phenotype but were markedly resistant to intestinal tumorigenesis induced by the APCmin mutation. These results establish that a cancer-associated SNP identified in human genome-wide association studies has a functional effect in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sur, Inderpreet Kaur -- Hallikas, Outi -- Vaharautio, Anna -- Yan, Jian -- Turunen, Mikko -- Enge, Martin -- Taipale, Minna -- Karhu, Auli -- Aaltonen, Lauri A -- Taipale, Jussi -- New York, N.Y. -- Science. 2012 Dec 7;338(6112):1360-3. doi: 10.1126/science.1228606.

    Description: Hirota et al. (Reports, 14 October 2011, p. 232) used spatial data to show that grasslands, savannas, and forests represent opposing stable states. Reanalyzing their data and drawing from temporal studies, we argue that spatial analyses underestimate the bistability of grasslands and savannas due to limitations of substituting space for time. We propose that temporal and spatial data are needed to predict critical transitions between grasslands and savannas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ratajczak, Zak -- Nippert, Jesse B -- New York, N.Y. -- Science. 2012 May 4;336(6081):541; author reply 541. doi: 10.1126/science.1219346.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, Kansas State University, 116 Ackert Hall, Manhattan, KS 66506, USA. zarata@ksu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22556235" target="_blank"〉PubMed〈/a〉

    A high-coverage genome sequence from an archaic Denisovan individual (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-09-01
    Description: We present a DNA library preparation method that has allowed us to reconstruct a high-coverage (30x) genome sequence of a Denisovan, an extinct relative of Neandertals. The quality of this genome allows a direct estimation of Denisovan heterozygosity indicating that genetic diversity in these archaic hominins was extremely low. It also allows tentative dating of the specimen on the basis of "missing evolution" in its genome, detailed measurements of Denisovan and Neandertal admixture into present-day human populations, and the generation of a near-complete catalog of genetic changes that swept to high frequency in modern humans since their divergence from Denisovans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3617501/" 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/PMC3617501/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, Matthias -- Kircher, Martin -- Gansauge, Marie-Theres -- Li, Heng -- Racimo, Fernando -- Mallick, Swapan -- Schraiber, Joshua G -- Jay, Flora -- Prufer, Kay -- de Filippo, Cesare -- Sudmant, Peter H -- Alkan, Can -- Fu, Qiaomei -- Do, Ron -- Rohland, Nadin -- Tandon, Arti -- Siebauer, Michael -- Green, Richard E -- Bryc, Katarzyna -- Briggs, Adrian W -- Stenzel, Udo -- Dabney, Jesse -- Shendure, Jay -- Kitzman, Jacob -- Hammer, Michael F -- Shunkov, Michael V -- Derevianko, Anatoli P -- Patterson, Nick -- Andres, Aida M -- Eichler, Evan E -- Slatkin, Montgomery -- Reich, David -- Kelso, Janet -- Paabo, Svante -- GM100233/GM/NIGMS NIH HHS/ -- R01 GM040282/GM/NIGMS NIH HHS/ -- R01 GM100233/GM/NIGMS NIH HHS/ -- R01-GM40282/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Oct 12;338(6104):222-6. doi: 10.1126/science.1224344.

    Fear of predation slows plant-litter decomposition (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-16
    Description: Aboveground consumers are believed to affect ecosystem functioning by regulating the quantity and quality of plant litter entering the soil. We uncovered a pathway whereby terrestrial predators regulate ecosystem processes via indirect control over soil community function. Grasshopper herbivores stressed by spider predators have a higher body carbon-to-nitrogen ratio than do grasshoppers raised without spiders. This change in elemental content does not slow grasshopper decomposition but perturbs belowground community function, decelerating the subsequent decomposition of plant litter. This legacy effect of predation on soil community function appears to be regulated by the amount of herbivore protein entering the soil.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hawlena, Dror -- Strickland, Michael S -- Bradford, Mark A -- Schmitz, Oswald J -- New York, N.Y. -- Science. 2012 Jun 15;336(6087):1434-8. doi: 10.1126/science.1220097.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Forestry and Environmental Studies, Yale University, 370 Prospect Street, New Haven, CT 06511, USA. dror.hawlena@mail.huji.ac.il〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22700928" target="_blank"〉PubMed〈/a〉

    Trim28 is required for epigenetic stability during mouse oocyte to embryo transition (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-24
    Description: Phenotypic variability in genetic disease is usually attributed to genetic background variation or environmental influence. Here, we show that deletion of a single gene, Trim28 (Kap1 or Tif1beta), from the maternal germ line alone, on an otherwise identical genetic background, results in severe phenotypic and epigenetic variability that leads to embryonic lethality. We identify early and minute epigenetic variations in blastomeres of the preimplantation embryo of these animals, suggesting that the embryonic lethality may result from the misregulation of genomic imprinting in mice lacking maternal Trim28. Our results reveal the long-range effects of a maternal gene deletion on epigenetic memory and illustrate the delicate equilibrium of maternal and zygotic factors during nuclear reprogramming.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Messerschmidt, Daniel M -- de Vries, Wilhelmine -- Ito, Mitsuteru -- Solter, Davor -- Ferguson-Smith, Anne -- Knowles, Barbara B -- 079249/Wellcome Trust/United Kingdom -- 095606/Wellcome Trust/United Kingdom -- MR/J001597/1/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2012 Mar 23;335(6075):1499-502. doi: 10.1126/science.1216154.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mammalian Development Group, Institute of Medical Biology, Singapore.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22442485" target="_blank"〉PubMed〈/a〉

    Description: Complex worker caste systems have contributed to the evolutionary success of advanced ant societies; however, little is known about the developmental processes underlying their origin and evolution. We combined hormonal manipulation, gene expression, and phylogenetic analyses with field observations to understand how novel worker subcastes evolve. We uncovered an ancestral developmental potential to produce a "supersoldier" subcaste that has been actualized at least two times independently in the hyperdiverse ant genus Pheidole. This potential has been retained and can be environmentally induced throughout the genus. Therefore, the retention and induction of this potential have facilitated the parallel evolution of supersoldiers through a process known as genetic accommodation. The recurrent induction of ancestral developmental potential may facilitate the adaptive and parallel evolution of phenotypes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rajakumar, Rajendhran -- San Mauro, Diego -- Dijkstra, Michiel B -- Huang, Ming H -- Wheeler, Diana E -- Hiou-Tim, Francois -- Khila, Abderrahman -- Cournoyea, Michael -- Abouheif, Ehab -- New York, N.Y. -- Science. 2012 Jan 6;335(6064):79-82. doi: 10.1126/science.1211451.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, McGill University, 1205 Avenue Dr. Penfield, Montreal, Quebec, Canada, H3A 1B1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22223805" target="_blank"〉PubMed〈/a〉

    MARF1 regulates essential oogenic processes in mice (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-24
    Description: Development of fertilization-competent oocytes depends on integrated processes controlling meiosis, cytoplasmic development, and maintenance of genomic integrity. We show that meiosis arrest female 1 (MARF1) is required for these processes in mammalian oocytes. Mutations of Marf1 cause female infertility characterized by up-regulation of a cohort of transcripts, increased retrotransposon expression, defective cytoplasmic maturation, and meiotic arrest. Up-regulation of protein phosphatase 2 catalytic subunit (PPP2CB) is key to the meiotic arrest phenotype. Moreover, Iap and Line1 retrotransposon messenger RNAs are also up-regulated, and, concomitantly, DNA double-strand breaks are elevated in mutant oocytes. Therefore MARF1, by suppressing levels of specific transcripts, is an essential regulator of important oogenic processes leading to female fertility and the development of healthy offspring.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3612990/" 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/PMC3612990/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Su, You-Qiang -- Sugiura, Koji -- Sun, Fengyun -- Pendola, Janice K -- Cox, Gregory A -- Handel, Mary Ann -- Schimenti, John C -- Eppig, John J -- CA34196/CA/NCI NIH HHS/ -- HD42137/HD/NICHD NIH HHS/ -- P01 HD042137/HD/NICHD NIH HHS/ -- P30 CA034196/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2012 Mar 23;335(6075):1496-9. doi: 10.1126/science.1214680.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Jackson Laboratory, Bar Harbor, ME 04609, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22442484" target="_blank"〉PubMed〈/a〉

    Detecting causality in complex ecosystems (2012)

    Details
    Publication Date: 2012-09-22
    Description: Identifying causal networks is important for effective policy and management recommendations on climate, epidemiology, financial regulation, and much else. We introduce a method, based on nonlinear state space reconstruction, that can distinguish causality from correlation. It extends to nonseparable weakly connected dynamic systems (cases not covered by the current Granger causality paradigm). The approach is illustrated both by simple models (where, in contrast to the real world, we know the underlying equations/relations and so can check the validity of our method) and by application to real ecological systems, including the controversial sardine-anchovy-temperature problem.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sugihara, George -- May, Robert -- Ye, Hao -- Hsieh, Chih-hao -- Deyle, Ethan -- Fogarty, Michael -- Munch, Stephan -- New York, N.Y. -- Science. 2012 Oct 26;338(6106):496-500. doi: 10.1126/science.1227079.

    The ancient drug salicylate directly activates AMP-activated protein kinase (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-04-21
    Description: Salicylate, a plant product, has been in medicinal use since ancient times. More recently, it has been replaced by synthetic derivatives such as aspirin and salsalate, both of which are rapidly broken down to salicylate in vivo. At concentrations reached in plasma after administration of salsalate or of aspirin at high doses, salicylate activates adenosine monophosphate-activated protein kinase (AMPK), a central regulator of cell growth and metabolism. Salicylate binds at the same site as the synthetic activator A-769662 to cause allosteric activation and inhibition of dephosphorylation of the activating phosphorylation site, threonine-172. In AMPK knockout mice, effects of salicylate to increase fat utilization and to lower plasma fatty acids in vivo were lost. Our results suggest that AMPK activation could explain some beneficial effects of salsalate and aspirin in humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3399766/" 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/PMC3399766/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hawley, Simon A -- Fullerton, Morgan D -- Ross, Fiona A -- Schertzer, Jonathan D -- Chevtzoff, Cyrille -- Walker, Katherine J -- Peggie, Mark W -- Zibrova, Darya -- Green, Kevin A -- Mustard, Kirsty J -- Kemp, Bruce E -- Sakamoto, Kei -- Steinberg, Gregory R -- Hardie, D Grahame -- 080982/Wellcome Trust/United Kingdom -- 097726/Wellcome Trust/United Kingdom -- MC_U127088492/Medical Research Council/United Kingdom -- Canadian Institutes of Health Research/Canada -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2012 May 18;336(6083):918-22. doi: 10.1126/science.1215327.

    Airborne transmission of influenza A/H5N1 virus between ferrets (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-23
    Description: Highly pathogenic avian influenza A/H5N1 virus can cause morbidity and mortality in humans but thus far has not acquired the ability to be transmitted by aerosol or respiratory droplet ("airborne transmission") between humans. To address the concern that the virus could acquire this ability under natural conditions, we genetically modified A/H5N1 virus by site-directed mutagenesis and subsequent serial passage in ferrets. The genetically modified A/H5N1 virus acquired mutations during passage in ferrets, ultimately becoming airborne transmissible in ferrets. None of the recipient ferrets died after airborne infection with the mutant A/H5N1 viruses. Four amino acid substitutions in the host receptor-binding protein hemagglutinin, and one in the polymerase complex protein basic polymerase 2, were consistently present in airborne-transmitted viruses. The transmissible viruses were sensitive to the antiviral drug oseltamivir and reacted well with antisera raised against H5 influenza vaccine strains. Thus, avian A/H5N1 influenza viruses can acquire the capacity for airborne transmission between mammals without recombination in an intermediate host and therefore constitute a risk for human pandemic influenza.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herfst, Sander -- Schrauwen, Eefje J A -- Linster, Martin -- Chutinimitkul, Salin -- de Wit, Emmie -- Munster, Vincent J -- Sorrell, Erin M -- Bestebroer, Theo M -- Burke, David F -- Smith, Derek J -- Rimmelzwaan, Guus F -- Osterhaus, Albert D M E -- Fouchier, Ron A M -- DP1-OD000490-01/OD/NIH HHS/ -- HHSN266200700010C/PHS HHS/ -- New York, N.Y. -- Science. 2012 Jun 22;336(6088):1534-41. doi: 10.1126/science.1213362.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Virology, Erasmus Medical Center, Rotterdam, The Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22723413" target="_blank"〉PubMed〈/a〉

    Elfn1 regulates target-specific release probability at CA1-interneuron synapses (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-10-09
    Description: Although synaptic transmission may be unidirectional, the establishment of synaptic connections with specific properties can involve bidirectional signaling. Pyramidal neurons in the hippocampus form functionally distinct synapses onto two types of interneurons. Excitatory synapses onto oriens-lacunosum moleculare (O-LM) interneurons are facilitating and have a low release probability, whereas synapses onto parvalbumin interneurons are depressing and have a high release probability. Here, we show that the extracellular leucine-rich repeat fibronectin containing 1 (Elfn1) protein is selectively expressed by O-LM interneurons and regulates presynaptic release probability to direct the formation of highly facilitating pyramidal-O-LM synapses. Thus, postsynaptic expression of Elfn1 in O-LM interneurons regulates presynaptic release probability, which confers target-specific synaptic properties to pyramidal cell axons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sylwestrak, Emily L -- Ghosh, Anirvan -- R01 NS067216/NS/NINDS NIH HHS/ -- R01NS067216/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2012 Oct 26;338(6106):536-40. doi: 10.1126/science.1222482.

    Rapamycin-induced insulin resistance is mediated by mTORC2 loss and uncoupled from longevity (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-31
    Description: Rapamycin, an inhibitor of mechanistic target of rapamycin complex 1 (mTORC1), extends the life spans of yeast, flies, and mice. Calorie restriction, which increases life span and insulin sensitivity, is proposed to function by inhibition of mTORC1, yet paradoxically, chronic administration of rapamycin substantially impairs glucose tolerance and insulin action. We demonstrate that rapamycin disrupted a second mTOR complex, mTORC2, in vivo and that mTORC2 was required for the insulin-mediated suppression of hepatic gluconeogenesis. Further, decreased mTORC1 signaling was sufficient to extend life span independently from changes in glucose homeostasis, as female mice heterozygous for both mTOR and mLST8 exhibited decreased mTORC1 activity and extended life span but had normal glucose tolerance and insulin sensitivity. Thus, mTORC2 disruption is an important mediator of the effects of rapamycin in vivo.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3324089/" 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/PMC3324089/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lamming, Dudley W -- Ye, Lan -- Katajisto, Pekka -- Goncalves, Marcus D -- Saitoh, Maki -- Stevens, Deanna M -- Davis, James G -- Salmon, Adam B -- Richardson, Arlan -- Ahima, Rexford S -- Guertin, David A -- Sabatini, David M -- Baur, Joseph A -- 1F32AG032833-01A1/AG/NIA NIH HHS/ -- CA129105/CA/NCI NIH HHS/ -- F32 AG032833/AG/NIA NIH HHS/ -- P30DK19525/DK/NIDDK NIH HHS/ -- R01 CA129105/CA/NCI NIH HHS/ -- R01 CA129105-05/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Mar 30;335(6076):1638-43. doi: 10.1126/science.1215135.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22461615" target="_blank"〉PubMed〈/a〉

    A logic-gated nanorobot for targeted transport of molecular payloads (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-02-22
    Description: We describe an autonomous DNA nanorobot capable of transporting molecular payloads to cells, sensing cell surface inputs for conditional, triggered activation, and reconfiguring its structure for payload delivery. The device can be loaded with a variety of materials in a highly organized fashion and is controlled by an aptamer-encoded logic gate, enabling it to respond to a wide array of cues. We implemented several different logical AND gates and demonstrate their efficacy in selective regulation of nanorobot function. As a proof of principle, nanorobots loaded with combinations of antibody fragments were used in two different types of cell-signaling stimulation in tissue culture. Our prototype could inspire new designs with different selectivities and biologically active payloads for cell-targeting tasks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Douglas, Shawn M -- Bachelet, Ido -- Church, George M -- New York, N.Y. -- Science. 2012 Feb 17;335(6070):831-4. doi: 10.1126/science.1214081.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wyss Institute for Biologically Inspired Engineering, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22344439" target="_blank"〉PubMed〈/a〉

    Secreted kinase phosphorylates extracellular proteins that regulate biomineralization (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-05-15
    Description: Protein phosphorylation is a fundamental mechanism regulating nearly every aspect of cellular life. Several secreted proteins are phosphorylated, but the kinases responsible are unknown. We identified a family of atypical protein kinases that localize within the Golgi apparatus and are secreted. Fam20C appears to be the Golgi casein kinase that phosphorylates secretory pathway proteins within S-x-E motifs. Fam20C phosphorylates the caseins and several secreted proteins implicated in biomineralization, including the small integrin-binding ligand, N-linked glycoproteins (SIBLINGs). Consequently, mutations in Fam20C cause an osteosclerotic bone dysplasia in humans known as Raine syndrome. Fam20C is thus a protein kinase dedicated to the phosphorylation of extracellular proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3754843/" 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/PMC3754843/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tagliabracci, Vincent S -- Engel, James L -- Wen, Jianzhong -- Wiley, Sandra E -- Worby, Carolyn A -- Kinch, Lisa N -- Xiao, Junyu -- Grishin, Nick V -- Dixon, Jack E -- DK018024-37/DK/NIDDK NIH HHS/ -- DK018849-36/DK/NIDDK NIH HHS/ -- GM094575/GM/NIGMS NIH HHS/ -- R01 DK018849/DK/NIDDK NIH HHS/ -- R37 DK018024/DK/NIDDK NIH HHS/ -- T32 CA009523/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Jun 1;336(6085):1150-3. doi: 10.1126/science.1217817.

    A single progenitor population switches behavior to maintain and repair esophageal epithelium (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-07-24
    Description: Diseases of the esophageal epithelium (EE), such as reflux esophagitis and cancer, are rising in incidence. Despite this, the cellular behaviors underlying EE homeostasis and repair remain controversial. Here, we show that in mice, EE is maintained by a single population of cells that divide stochastically to generate proliferating and differentiating daughters with equal probability. In response to challenge with all-trans retinoic acid (atRA), the balance of daughter cell fate is unaltered, but the rate of cell division increases. However, after wounding, cells reversibly switch to producing an excess of proliferating daughters until the wound has closed. Such fate-switching enables a single progenitor population to both maintain and repair tissue without the need for a "reserve" slow-cycling stem cell pool.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3527005/" 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/PMC3527005/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Doupe, David P -- Alcolea, Maria P -- Roshan, Amit -- Zhang, Gen -- Klein, Allon M -- Simons, Benjamin D -- Jones, Philip H -- 079249/Wellcome Trust/United Kingdom -- 092096/Wellcome Trust/United Kingdom -- G0601740/Medical Research Council/United Kingdom -- G0700600/1/National Centre for the Replacement, Refinement and Reduction of Animals in Research/United Kingdom -- G0800784/Medical Research Council/United Kingdom -- MC_U105370181/Medical Research Council/United Kingdom -- U.1053.00.010(70181)/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2012 Aug 31;337(6098):1091-3. doi: 10.1126/science.1218835.

    Locally synchronized synaptic inputs (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-01-24
    Description: Synaptic inputs on dendrites are nonlinearly converted to action potential outputs, yet the spatiotemporal patterns of dendritic activation remain to be elucidated at single-synapse resolution. In rodents, we optically imaged synaptic activities from hundreds of dendritic spines in hippocampal and neocortical pyramidal neurons ex vivo and in vivo. Adjacent spines were frequently synchronized in spontaneously active networks, thereby forming dendritic foci that received locally convergent inputs from presynaptic cell assemblies. This precise subcellular geometry manifested itself during N-methyl-D-aspartate receptor-dependent circuit remodeling. Thus, clustered synaptic plasticity is innately programmed to compartmentalize correlated inputs along dendrites and may reify nonlinear synaptic integration.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takahashi, Naoya -- Kitamura, Kazuo -- Matsuo, Naoki -- Mayford, Mark -- Kano, Masanobu -- Matsuki, Norio -- Ikegaya, Yuji -- New York, N.Y. -- Science. 2012 Jan 20;335(6066):353-6. doi: 10.1126/science.1210362.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Chemical Pharmacology, Graduate School of Pharmaceutical Sciences, The University of Tokyo, Bunkyo-ku, Tokyo, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22267814" target="_blank"〉PubMed〈/a〉

    Mutations in the neverland gene turned Drosophila pachea into an obligate specialist species (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-09-29
    Description: Most living species exploit a limited range of resources. However, little is known about how tight associations build up during evolution between such specialist species and the hosts they use. We examined the dependence of Drosophila pachea on its single host, the senita cactus. Several amino acid changes in the Neverland oxygenase rendered D. pachea unable to transform cholesterol into 7-dehydrocholesterol (the first reaction in the steroid hormone biosynthetic pathway in insects) and thus made D. pachea dependent on the uncommon sterols of its host plant. The neverland mutations increase survival on the cactus's unusual sterols and are in a genomic region that faced recent positive selection. This study illustrates how relatively few genetic changes in a single gene may restrict the ecological niche of a species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4729188/" 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/PMC4729188/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lang, Michael -- Murat, Sophie -- Clark, Andrew G -- Gouppil, Geraldine -- Blais, Catherine -- Matzkin, Luciano M -- Guittard, Emilie -- Yoshiyama-Yanagawa, Takuji -- Kataoka, Hiroshi -- Niwa, Ryusuke -- Lafont, Rene -- Dauphin-Villemant, Chantal -- Orgogozo, Virginie -- AI064950/AI/NIAID NIH HHS/ -- R01 AI064950/AI/NIAID NIH HHS/ -- R01 HG003229/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2012 Sep 28;337(6102):1658-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉CNRS UMR7592, Universite Paris Diderot, Sorbonne Paris Cite, Institut Jacques Monod, Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23019649" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 2012-11-10
    Description: Despite more than 30 years of work on the Wnt signaling pathway, the basic mechanism of how the extracellular Wnt signal increases the intracellular concentration of beta-catenin is still contentious. Circumventing much of the detailed biochemistry, we used basic principles of chemical kinetics coupled with quantitative measurements to define the reactions on beta-catenin directly affected by the Wnt signal. We conclude that the core signal transduction mechanism is relatively simple, with only two regulated phosphorylation steps. Their partial inhibition gives rise to the full dynamics of the response and subsequently maintains a steady state in which the concentration of beta-catenin is increased.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hernandez, Ana R -- Klein, Allon M -- Kirschner, Marc W -- New York, N.Y. -- Science. 2012 Dec 7;338(6112):1337-40. doi: 10.1126/science.1228734.

    Membrane fusion intermediates via directional and full assembly of the SNARE complex (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-02
    Description: Cellular membrane fusion is thought to proceed through intermediates including docking of apposed lipid bilayers, merging of proximal leaflets to form a hemifusion diaphragm, and fusion pore opening. A membrane-bridging four-helix complex of soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) mediates fusion. However, how assembly of the SNARE complex generates docking and other fusion intermediates is unknown. Using a cell-free reaction, we identified intermediates visually and then arrested the SNARE fusion machinery when fusion was about to begin. Partial and directional assembly of SNAREs tightly docked bilayers, but efficient fusion and an extended form of hemifusion required assembly beyond the core complex to the membrane-connecting linkers. We propose that straining of lipids at the edges of an extended docking zone initiates fusion.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3677693/" 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/PMC3677693/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hernandez, Javier M -- Stein, Alexander -- Behrmann, Elmar -- Riedel, Dietmar -- Cypionka, Anna -- Farsi, Zohreh -- Walla, Peter J -- Raunser, Stefan -- Jahn, Reinhard -- 3P01GM072694-05S1/GM/NIGMS NIH HHS/ -- P01 GM072694/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Jun 22;336(6088):1581-4. doi: 10.1126/science.1221976.

    Details
    Publication Date: 2012-11-10
    Description: Iron lies at the center of a battle for nutritional resource between higher organisms and their microbial pathogens. The iron status of the human host affects the pathogenicity of numerous infections including malaria, HIV-1, and tuberculosis. Hepcidin, an antimicrobial-like peptide hormone, has emerged as the master regulator of iron metabolism. Hepcidin controls the absorption of dietary iron and the distribution of iron among cell types in the body, and its synthesis is regulated by both iron and innate immunity. We describe how hepcidin integrates signals from diverse physiological inputs, forming a key molecular bridge between iron trafficking and response to infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drakesmith, Hal -- Prentice, Andrew M -- G0700844/Medical Research Council/United Kingdom -- G0901149/Medical Research Council/United Kingdom -- MC-A760-5QX00/Medical Research Council/United Kingdom -- MC_U123292699/Medical Research Council/United Kingdom -- MC_U123292700/Medical Research Council/United Kingdom -- MC_U123292701/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2012 Nov 9;338(6108):768-72. doi: 10.1126/science.1224577.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Immunology Group and Medical Research Council (MRC) Human Immunology Unit, MRC Weatherall Institute of Molecular Medicine, University of Oxford, John Radcliffe Hospital, Oxford, UK. alexander.drakesmith@ndm.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23139325" target="_blank"〉PubMed〈/a〉

    Identification and functional expression of the mitochondrial pyruvate carrier (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-05-26
    Description: The transport of pyruvate, the end product of glycolysis, into mitochondria is an essential process that provides the organelle with a major oxidative fuel. Although the existence of a specific mitochondrial pyruvate carrier (MPC) has been anticipated, its molecular identity remained unknown. We report that MPC is a heterocomplex formed by two members of a family of previously uncharacterized membrane proteins that are conserved from yeast to mammals. Members of the MPC family were found in the inner mitochondrial membrane, and yeast mutants lacking MPC proteins showed severe defects in mitochondrial pyruvate uptake. Coexpression of mouse MPC1 and MPC2 in Lactococcus lactis promoted transport of pyruvate across the membrane. These observations firmly establish these proteins as essential components of the MPC.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herzig, Sebastien -- Raemy, Etienne -- Montessuit, Sylvie -- Veuthey, Jean-Luc -- Zamboni, Nicola -- Westermann, Benedikt -- Kunji, Edmund R S -- Martinou, Jean-Claude -- MC_U105663139/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2012 Jul 6;337(6090):93-6. doi: 10.1126/science.1218530.

    Erasure of a spinal memory trace of pain by a brief, high-dose opioid administration (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-01-17
    Description: Painful stimuli activate nociceptive C fibers and induce synaptic long-term potentiation (LTP) at their spinal terminals. LTP at C-fiber synapses represents a cellular model for pain amplification (hyperalgesia) and for a memory trace of pain. mu-Opioid receptor agonists exert a powerful but reversible depression at C-fiber synapses that renders the continuous application of low opioid doses the gold standard in pain therapy. We discovered that brief application of a high opioid dose reversed various forms of activity-dependent LTP at C-fiber synapses. Depotentiation involved Ca(2+)-dependent signaling and normalization of the phosphorylation state of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors. This also reversed hyperalgesia in behaving animals. Opioids thus not only temporarily dampen pain but may also erase a spinal memory trace of pain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drdla-Schutting, Ruth -- Benrath, Justus -- Wunderbaldinger, Gabriele -- Sandkuhler, Jurgen -- New York, N.Y. -- Science. 2012 Jan 13;335(6065):235-8. doi: 10.1126/science.1211726.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurophysiology, Center for Brain Research, Medical University of Vienna, A-1090 Vienna, Austria.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22246779" target="_blank"〉PubMed〈/a〉

    Impacts of biodiversity loss escalate through time as redundancy fades (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-05-05
    Description: Plant diversity generally promotes biomass production, but how the shape of the response curve changes with time remains unclear. This is a critical knowledge gap because the shape of this relationship indicates the extent to which loss of the first few species will influence biomass production. Using two long-term (〉/=13 years) biodiversity experiments, we show that the effects of diversity on biomass productivity increased and became less saturating over time. Our analyses suggest that effects of diversity-dependent ecosystem feedbacks and interspecific complementarity accumulate over time, causing high-diversity species combinations that appeared functionally redundant during early years to become more functionally unique through time. Consequently, simplification of diverse ecosystems will likely have greater negative impacts on ecosystem functioning than has been suggested by short-term experiments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reich, Peter B -- Tilman, David -- Isbell, Forest -- Mueller, Kevin -- Hobbie, Sarah E -- Flynn, Dan F B -- Eisenhauer, Nico -- New York, N.Y. -- Science. 2012 May 4;336(6081):589-92. doi: 10.1126/science.1217909.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Forest Resources, University of Minnesota, St. Paul, MN 55108, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22556253" target="_blank"〉PubMed〈/a〉

    Broadly neutralizing antibodies present new prospects to counter highly antigenically diverse viruses (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-07-17
    Description: Certain human pathogens avoid elimination by our immune system by rapidly mutating the surface protein sites targeted by antibody responses, and consequently they tend to be problematic for vaccine development. The behavior described is prominent for a subset of viruses--the highly antigenically diverse viruses--which include HIV, influenza, and hepatitis C viruses. However, these viruses do harbor highly conserved exposed sites, usually associated with function, which can be targeted by broadly neutralizing antibodies. Until recently, not many such antibodies were known, but advances in the field have enabled increasing numbers to be identified. Molecular characterizations of the antibodies and, most importantly, of the sites of vulnerability that they recognize give hope for the discovery of new vaccines and drugs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3600854/" 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/PMC3600854/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burton, Dennis R -- Poignard, Pascal -- Stanfield, Robyn L -- Wilson, Ian A -- P01 AI082362/AI/NIAID NIH HHS/ -- R01 AI084817/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2012 Jul 13;337(6091):183-6. doi: 10.1126/science.1225416.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology and Microbial Science and International AIDS Vaccine Initiative Neutralizing Antibody Center, The Scripps Research Institute, La Jolla, CA 92037, USA. burton@scripps.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22798606" target="_blank"〉PubMed〈/a〉

    A periciliary brush promotes the lung health by separating the mucus layer from airway epithelia (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-08-28
    Description: Mucus clearance is the primary defense mechanism that protects airways from inhaled infectious and toxic agents. In the current gel-on-liquid mucus clearance model, a mucus gel is propelled on top of a "watery" periciliary layer surrounding the cilia. However, this model fails to explain the formation of a distinct mucus layer in health or why mucus clearance fails in disease. We propose a gel-on-brush model in which the periciliary layer is occupied by membrane-spanning mucins and mucopolysaccharides densely tethered to the airway surface. This brush prevents mucus penetration into the periciliary space and causes mucus to form a distinct layer. The relative osmotic moduli of the mucus and periciliary brush layers explain both the stability of mucus clearance in health and its failure in airway disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3633213/" 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/PMC3633213/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Button, Brian -- Cai, Li-Heng -- Ehre, Camille -- Kesimer, Mehmet -- Hill, David B -- Sheehan, John K -- Boucher, Richard C -- Rubinstein, Michael -- HHSN268200900020/PHS HHS/ -- K01DK080847/DK/NIDDK NIH HHS/ -- P01HL108808/HL/NHLBI NIH HHS/ -- P01HL110873-01/HL/NHLBI NIH HHS/ -- P01HL34322/HL/NHLBI NIH HHS/ -- P30DK065988/DK/NIDDK NIH HHS/ -- P50HL107168/HL/NHLBI NIH HHS/ -- P50HL107168-01/HL/NHLBI NIH HHS/ -- R01 HL103940/HL/NHLBI NIH HHS/ -- R01HL077546/HL/NHLBI NIH HHS/ -- R01HL103940/HL/NHLBI NIH HHS/ -- UL1-RR025747/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2012 Aug 24;337(6097):937-41. doi: 10.1126/science.1223012.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cystic Fibrosis Research and Treatment Center, University of North Carolina, Chapel Hill, NC 27599-7248, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22923574" target="_blank"〉PubMed〈/a〉

    Structural basis for DNA damage-dependent poly(ADP-ribosyl)ation by human PARP-1 (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-05-15
    Description: Poly(ADP-ribose) polymerase-1 (PARP-1) (ADP, adenosine diphosphate) has a modular domain architecture that couples DNA damage detection to poly(ADP-ribosyl)ation activity through a poorly understood mechanism. Here, we report the crystal structure of a DNA double-strand break in complex with human PARP-1 domains essential for activation (Zn1, Zn3, WGR-CAT). PARP-1 engages DNA as a monomer, and the interaction with DNA damage organizes PARP-1 domains into a collapsed conformation that can explain the strong preference for automodification. The Zn1, Zn3, and WGR domains collectively bind to DNA, forming a network of interdomain contacts that links the DNA damage interface to the catalytic domain (CAT). The DNA damage-induced conformation of PARP-1 results in structural distortions that destabilize the CAT. Our results suggest that an increase in CAT protein dynamics underlies the DNA-dependent activation mechanism of PARP-1.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3532513/" 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/PMC3532513/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Langelier, Marie-France -- Planck, Jamie L -- Roy, Swati -- Pascal, John M -- P30 EB009998/EB/NIBIB NIH HHS/ -- P30CA56036/CA/NCI NIH HHS/ -- R01 GM087282/GM/NIGMS NIH HHS/ -- R01087282/PHS HHS/ -- New York, N.Y. -- Science. 2012 May 11;336(6082):728-32. doi: 10.1126/science.1216338.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, The Kimmel Cancer Center, Thomas Jefferson University, Philadelphia, PA 19107, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22582261" target="_blank"〉PubMed〈/a〉

    Bateman in nature: predation on offspring reduces the potential for sexual selection (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-11-10
    Description: Sexual selection is driven by competition for mates, and the advantage of a competitor is determined by the number of offspring it produces. Early experiments by Angus Bateman characterized this interaction, and the quantitative relationship between a male's number of mates and number of offspring is known as the Bateman slope. Sexual dimorphism, one of the most obvious results of sexual selection, largely requires a positive Bateman relationship, and the slope provides an estimate of the potential for sexual selection. However, natural selection from the environment can also influence male success, as can random effects, and some have argued for inclusion of the latter in calculations of mate success. Data from pronghorn (Antilocapra americana) reveal the presence of a positive Bateman slope in each year of a 10-year study. We found no evidence that random effects skewed male mating success; however, substantial yearly variation in the Bateman slope due to predation on fawns was evident. These results support the validity of the Bateman relationship, yet they also demonstrate that environmental or extrinsic influences can limit the potential for sexual selection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Byers, John -- Dunn, Stacey -- New York, N.Y. -- Science. 2012 Nov 9;338(6108):802-4. doi: 10.1126/science.1224660.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, University of Idaho, Moscow, ID 83844-3051, USA. jbyers@uidaho.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23139332" target="_blank"〉PubMed〈/a〉

    Structural probing of a protein phosphatase 2A network by chemical cross-linking and mass spectrometry (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-09-18
    Description: The identification of proximate amino acids by chemical cross-linking and mass spectrometry (XL-MS) facilitates the structural analysis of homogeneous protein complexes. We gained distance restraints on a modular interaction network of protein complexes affinity-purified from human cells by applying an adapted XL-MS protocol. Systematic analysis of human protein phosphatase 2A (PP2A) complexes identified 176 interprotein and 570 intraprotein cross-links that link specific trimeric PP2A complexes to a multitude of adaptor proteins that control their cellular functions. Spatial restraints guided molecular modeling of the binding interface between immunoglobulin binding protein 1 (IGBP1) and PP2A and revealed the topology of TCP1 ring complex (TRiC) chaperonin interacting with the PP2A regulatory subunit 2ABG. This study establishes XL-MS as an integral part of hybrid structural biology approaches for the analysis of endogenous protein complexes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herzog, Franz -- Kahraman, Abdullah -- Boehringer, Daniel -- Mak, Raymond -- Bracher, Andreas -- Walzthoeni, Thomas -- Leitner, Alexander -- Beck, Martin -- Hartl, Franz-Ulrich -- Ban, Nenad -- Malmstrom, Lars -- Aebersold, Ruedi -- New York, N.Y. -- Science. 2012 Sep 14;337(6100):1348-52. doi: 10.1126/science.1221483.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Institute of Molecular Systems Biology, Eidgenossische Technische Hochschule Zurich, Wolfgang-Pauli Strasse 16, 8093 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22984071" target="_blank"〉PubMed〈/a〉

    Highly conserved protective epitopes on influenza B viruses (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-08-11
    Description: Identification of broadly neutralizing antibodies against influenza A viruses has raised hopes for the development of monoclonal antibody-based immunotherapy and "universal" vaccines for influenza. However, a substantial part of the annual flu burden is caused by two cocirculating, antigenically distinct lineages of influenza B viruses. Here, we report human monoclonal antibodies, CR8033, CR8071, and CR9114, that protect mice against lethal challenge from both lineages. Antibodies CR8033 and CR8071 recognize distinct conserved epitopes in the head region of the influenza B hemagglutinin (HA), whereas CR9114 binds a conserved epitope in the HA stem and protects against lethal challenge with influenza A and B viruses. These antibodies may inform on development of monoclonal antibody-based treatments and a universal flu vaccine for all influenza A and B viruses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3538841/" 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/PMC3538841/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dreyfus, Cyrille -- Laursen, Nick S -- Kwaks, Ted -- Zuijdgeest, David -- Khayat, Reza -- Ekiert, Damian C -- Lee, Jeong Hyun -- Metlagel, Zoltan -- Bujny, Miriam V -- Jongeneelen, Mandy -- van der Vlugt, Remko -- Lamrani, Mohammed -- Korse, Hans J W M -- Geelen, Eric -- Sahin, Ozcan -- Sieuwerts, Martijn -- Brakenhoff, Just P J -- Vogels, Ronald -- Li, Olive T W -- Poon, Leo L M -- Peiris, Malik -- Koudstaal, Wouter -- Ward, Andrew B -- Wilson, Ian A -- Goudsmit, Jaap -- Friesen, Robert H E -- GM080209/GM/NIGMS NIH HHS/ -- P41RR001209/RR/NCRR NIH HHS/ -- RR017573/RR/NCRR NIH HHS/ -- T32 GM080209/GM/NIGMS NIH HHS/ -- U54 GM094586/GM/NIGMS NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Sep 14;337(6100):1343-8. doi: 10.1126/science.1222908.

    Double burden of noncommunicable and infectious diseases in developing countries (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-09-22
    Description: On top of the unfinished agenda of infectious diseases in low- and middle-income countries, development, industrialization, urbanization, investment, and aging are drivers of an epidemic of noncommunicable diseases (NCDs). Malnutrition and infection in early life increase the risk of chronic NCDs in later life, and in adult life, combinations of major NCDs and infections, such as diabetes and tuberculosis, can interact adversely. Because intervention against either health problem will affect the other, intervening jointly against noncommunicable and infectious diseases, rather than competing for limited funds, is an important policy consideration requiring new thinking and approaches.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bygbjerg, I C -- New York, N.Y. -- Science. 2012 Sep 21;337(6101):1499-501.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Copenhagen School of Global Health, Department of International Health, Immunology and Microbiology, Faculty of Health Sciences, University of Copenhagen, 5 Oster Farimagsgade, DK-1014, Copenhagen K, Denmark. iby@sund.ku.dk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22997329" target="_blank"〉PubMed〈/a〉

    Turbulence, cleavage, and the naked embryo: a case for coral clones (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-03
    Description: After mass spawning events, coral embryos, lacking the protective capsule of other metazoans, are directly exposed to the environment at the ocean surface. Here, we present evidence that modest turbulence disrupts the integrity of these embryos, which fragment into totipotent cells that develop into proportionately smaller functional larvae. The level of turbulence required to fragment coral embryos can be generated from small wind-generated waves, which occur frequently during coral spawning on the Great Barrier Reef. The formation of planktonic coral clones, through natural embryo fragmentation of broadcast spawn, is a previously unknown mode of reproduction in the animal kingdom.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heyward, A J -- Negri, A P -- New York, N.Y. -- Science. 2012 Mar 2;335(6072):1064. doi: 10.1126/science.1216055.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Australian Institute of Marine Science (AIMS), The University of Western Australia Oceans Institute, WA, Australia. a.heyward@aims.gov.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22383841" target="_blank"〉PubMed〈/a〉

    Actin network architecture can determine myosin motor activity (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-09
    Description: The organization of actin filaments into higher-ordered structures governs eukaryotic cell shape and movement. Global actin network size and architecture are maintained in a dynamic steady state through regulated assembly and disassembly. Here, we used experimentally defined actin structures in vitro to investigate how the activity of myosin motors depends on network architecture. Direct visualization of filaments revealed myosin-induced actin network deformation. During this reorganization, myosins selectively contracted and disassembled antiparallel actin structures, while parallel actin bundles remained unaffected. The local distribution of nucleation sites and the resulting orientation of actin filaments appeared to regulate the scalability of the contraction process. This "orientation selection" mechanism for selective contraction and disassembly suggests how the dynamics of the cellular actin cytoskeleton can be spatially controlled by actomyosin contractility.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3649007/" 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/PMC3649007/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reymann, Anne-Cecile -- Boujemaa-Paterski, Rajaa -- Martiel, Jean-Louis -- Guerin, Christophe -- Cao, Wenxiang -- Chin, Harvey F -- De La Cruz, Enrique M -- Thery, Manuel -- Blanchoin, Laurent -- GM097348/GM/NIGMS NIH HHS/ -- R01 GM097348/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Jun 8;336(6086):1310-4. doi: 10.1126/science.1221708.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Recherches en Technologies et Sciences pour le Vivant (iRTSV), Centre National de la Recherche Scientifique (CNRS)-Commissariat a l'Energie Atomique et aux Energies Alternatives (CEA)-Institut National de la Recherche Agronomique (INRA), Grenoble, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22679097" target="_blank"〉PubMed〈/a〉
