    Description: Separation and purification are critical industrial processes for separating components of chemical mixtures, and these processes account for about half of industrial energy usage (1). Gas mixtures of compounds with very similar physical properties are particularly difficult to separate. On pages 137 and 141 of this issue, Cadiau et al. (2) and Cui et al. (3), respectively, show that microporous materials can be designed to have high adsorption capacity and selectivity for particular hydrocarbons, enabling energy-efficient separation. Author: Jerry Y.

    Description: Biomass-degrading microorganisms use lytic polysaccharide monooxygenase (LPMO) enzymes to help digest cellulose, chitin, and starch. By cleaving otherwise inaccessible crystalline cellulose chains, these enzymes provide access to hydrolytic enzymes. LPMOs are of interest to biotechnology because efficient depolymerization of cellulose is a major bottleneck for the production of biologically based chemicals and fuels. On page 1098 of this issue, Kracher et al. (1) compare LPMO-reducing substrates in fungi from different taxonomic groups and lifestyles, based on both biochemical and genomic evidence. The results provide insights into reductive activation of LPMO that are important for developing more efficient industrial enzymes for lignocellulose biorefineries. Author: Angel T. Martínez

    Description: The comment and response concerning the report of oxidation of methane to methanol by water (Reports, 5 May 2017, p. 523) do not fully capture the implications of thermodynamic limitations. A nonisothermal process in which each cycle requires a large temperature swing and permits only substoichiometric methane conversion surely could not be carried out on any practical scale.

    Description: Labinger argues that stepwise reaction of methane with water to produce methanol and hydrogen will never be commercially feasible because of its substoichiometric basis with respect to the active site and the requirement of a large temperature swing. This comment is not touching any new ground, beyond describing the thermodynamic feasibility, thermal cycling, and the role of water as discussed previously. Most important, it does not have a solid numerical basis.

    Description: Vinyl carbocations have been the subject of extensive experimental and theoretical studies over the past five decades. Despite this long history in chemistry, the utility of vinyl cations in chemical synthesis has been limited, with most reactivity studies focusing on solvolysis reactions or intramolecular processes. Here we report synthetic and mechanistic studies of vinyl cations generated through silylium–weakly coordinating anion catalysis. We find that these reactive intermediates undergo mild intermolecular carbon-carbon bond–forming reactions, including carbon-hydrogen (C–H) insertion into unactivated sp 3 C–H bonds and reductive Friedel-Crafts reactions with arenes. Moreover, we conducted computational studies of these alkane C–H functionalization reactions and discovered that they proceed through nonclassical, ambimodal transition structures. This reaction manifold provides a framework for the catalytic functionalization of hydrocarbons using simple ketone derivatives.

    Description: It is commonly assumed that recognition and discrimination of chirality, both in nature and in artificial systems, depend solely on spatial effects. However, recent studies have suggested that charge redistribution in chiral molecules manifests an enantiospecific preference in electron spin orientation. We therefore reasoned that the induced spin polarization may affect enantiorecognition through exchange interactions. Here we show experimentally that the interaction of chiral molecules with a perpendicularly magnetized substrate is enantiospecific. Thus, one enantiomer adsorbs preferentially when the magnetic dipole is pointing up, whereas the other adsorbs faster for the opposite alignment of the magnetization. The interaction is not controlled by the magnetic field per se, but rather by the electron spin orientations, and opens prospects for a distinct approach to enantiomeric separations.

    Description: Theory has established the importance of geometric phase (GP) effects in the adiabatic dynamics of molecular systems with a conical intersection connecting the ground- and excited-state potential energy surfaces, but direct observation of their manifestation in chemical reactions remains a major challenge. Here, we report a high-resolution crossed molecular beams study of the H + HD -〉 H 2 + D reaction at a collision energy slightly above the conical intersection. Velocity map ion imaging revealed fast angular oscillations in product quantum state–resolved differential cross sections in the forward scattering direction for H 2 products at specific rovibrational levels. The experimental results agree with adiabatic quantum dynamical calculations only when the GP effect is included.

    Description: The chemistry of the carbonyl group is essential to modern organic synthesis. The preparation of substituted, enantioenriched 1,3- or 1,5-dicarbonyls is well developed, as their disconnection naturally follows from the intrinsic polarity of the carbonyl group. By contrast, a general enantioselective access to quaternary stereocenters in acyclic 1,4-dicarbonyl systems remains an unresolved problem, despite the tremendous importance of 2,3-substituted 1,4-dicarbonyl motifs in natural products and drug scaffolds. Here we present a broad enantioselective and stereodivergent strategy to access acyclic, polysubstituted 1,4-dicarbonyls via acid-catalyzed [3,3]-sulfonium rearrangement starting from vinyl sulfoxides and ynamides. The stereochemistry at sulfur governs the absolute sense of chiral induction, whereas the double bond geometry dictates the relative configuration of the final products.

    Description: With the recent soaring production of natural gas, the use of methane and other light hydrocarbon feedstocks as starting materials in synthetic transformations is becoming increasingly economically attractive, although it remains chemically challenging. We report the development of photocatalytic C–H amination, alkylation, and arylation of methane, ethane, and higher alkanes under visible light irradiation at ambient temperature. High catalytic efficiency (turnover numbers up to 2900 for methane and 9700 for ethane) and selectivity were achieved using abundant, inexpensive cerium salts as photocatalysts. Ligand-to-metal charge transfer excitation generated alkoxy radicals from simple alcohols that in turn acted as hydrogen atom transfer catalysts. The mixed-phase gas/liquid reaction was adapted to continuous flow, enabling the efficient use of gaseous feedstocks in scalable photocatalytic transformations.

    Description: Intrigued by the potential of nanoscale machines, scientists have long attempted to control molecular motion. We monitored the individual 0.7-nanometer steps of a single molecular hopper as it moved in an electric field along a track in a nanopore controlled by a chemical ratchet. The hopper demonstrated characteristics desired in a moving molecule: defined start and end points, processivity, no chemical fuel requirement, directional motion, and external control. The hopper was readily functionalized to carry cargos. For example, a DNA molecule could be ratcheted along the track in either direction, a prerequisite for nanopore sequencing.

    Description: Phosphorothioate nucleotides have emerged as powerful pharmacological substitutes of their native phosphodiester analogs with important translational applications in antisense oligonucleotide (ASO) therapeutics and cyclic dinucleotide (CDN) synthesis. Stereocontrolled installation of this chiral motif has long been hampered by the systemic use of phosphorus(III) [P(III)]–based reagent systems as the sole practical means of oligonucleotide assembly. A fundamentally different approach is described herein: the invention of a P(V)-based reagent platform for programmable, traceless, diastereoselective phosphorus-sulfur incorporation. The power of this reagent system is demonstrated through the robust and stereocontrolled synthesis of various nucleotidic architectures, including ASOs and CDNs, via an efficient, inexpensive, and operationally simple protocol.

    Description: Here we report an anomalous porous molecular crystal built of C–H···N-bonded double-layered roof-floor components and wall components of a segregatively interdigitated architecture. This complicated porous structure consists of only one type of fully aromatic multijoint molecule carrying three identical dipyridylphenyl wedges. Despite its high symmetry, this molecule accomplishes difficult tasks by using two of its three wedges for roof-floor formation and using its other wedge for wall formation. Although a C–H···N bond is extremely labile, the porous crystal maintains its porosity until thermal breakdown of the C–H···N bonds at 202°C occurs, affording a nonporous polymorph. Though this nonporous crystal survives even at 325°C, it can retrieve the parent porosity under acetonitrile vapor. These findings show how one can translate simplicity into ultrahigh complexity.

    Description: Some of the simplest and most powerful carbon-carbon bond forming strategies take advantage of readily accessible ubiquitous motifs: carbonyls and olefins. Here we report a fundamentally distinct mode of reactivity between carbonyls and olefins that differs from established acid-catalyzed carbonyl-ene, Prins, and carbonyl-olefin metathesis reaction paths. A range of epsilon, zeta-unsaturated ketones undergo Brønsted acid–catalyzed intramolecular cyclization to provide tetrahydrofluorene products via the formation of two new carbon-carbon bonds. Theoretical calculations and accompanying mechanistic studies suggest that this carbocyclization reaction proceeds through the intermediacy of a transient oxetane formed by oxygen atom transfer. The complex polycyclic frameworks in this product class appear as common substructures in organic materials, bioactive natural products, and recently developed pharmaceuticals.

    Description: Alkene aminoarylation with a single, bifunctional reagent is a concise synthetic strategy. We report a catalytic protocol for the addition of arylsulfonylacetamides across electron-rich alkenes with complete anti-Markovnikov regioselectivity and excellent diastereoselectivity to provide 2,2-diarylethylamines. In this process, single-electron alkene oxidation enables carbon-nitrogen bond formation to provide a key benzylic radical poised for a Smiles-Truce 1,5-aryl shift. This reaction is redox-neutral, exhibits broad functional group compatibility, and occurs at room temperature with loss of sulfur dioxide. As this process is driven by visible light, uses readily available starting materials, and demonstrates convergent synthesis, it is well suited for use in a variety of synthetic endeavors.

    Description: Photocatalysis based on optically active, "plasmonic" metal nanoparticles has emerged as a promising approach to facilitate light-driven chemical conversions under far milder conditions than thermal catalysis. However, an understanding of the relation between thermal and electronic excitations has been lacking. We report the substantial light-induced reduction of the thermal activation barrier for ammonia decomposition on a plasmonic photocatalyst. We introduce the concept of a light-dependent activation barrier to account for the effect of light illumination on electronic and thermal excitations in a single unified picture. This framework provides insight into the specific role of hot carriers in plasmon-mediated photochemistry, which is critically important for designing energy-efficient plasmonic photocatalysts.

    Description: Single-electron reduction of a carbonyl to a ketyl enables access to a polarity-reversed platform of reactivity for this cornerstone functional group. However, the synthetic utility of the ketyl radical is hindered by the strong reductants necessary for its generation, which also limit its reactivity to net reductive mechanisms. We report a strategy for net redox-neutral generation and reaction of ketyl radicals. The in situ conversion of aldehydes to α-acetoxy iodides lowers their reduction potential by more than 1 volt, allowing for milder access to the corresponding ketyl radicals and an oxidative termination event. Upon subjecting these iodides to a dimanganese decacarbonyl precatalyst and visible light irradiation, an atom transfer radical addition (ATRA) mechanism affords a broad scope of vinyl iodide products with high Z -selectivity.

    Description: Reactions that form a product with the same reactive functionality as that of one of the starting compounds frequently end in oligomerization. As a salient example, selective aldol coupling of the smallest, though arguably most useful, enolizable aldehyde, acetaldehyde, with just one partner substrate has proven to be extremely challenging. Here, we report a highly enantioselective Mukaiyama aldol reaction with the simple triethylsilyl (TES) and tert -butyldimethylsilyl (TBS) enolates of acetaldehyde and various aliphatic and aromatic acceptor aldehydes. The reaction is catalyzed by recently developed, strongly acidic imidodiphosphorimidates (IDPi), which, like enzymes, display a confined active site but, like small-molecule catalysts, have a broad substrate scope. The process is scalable, fast, efficient (0.5 to 1.5 mole % catalyst loading), and greatly simplifies access to highly valuable silylated acetaldehyde aldols.

    Description: Single-molecule magnets (SMMs) containing only one metal center may represent the lower size limit for molecule-based magnetic information storage materials. Their current drawback is that all SMMs require liquid-helium cooling to show magnetic memory effects. We now report a chemical strategy to access the dysprosium metallocene cation [(Cp i Pr5 )Dy(Cp*)] + (Cp i Pr5 , penta-iso-propylcyclopentadienyl; Cp *, pentamethylcyclopentadienyl), which displays magnetic hysteresis above liquid-nitrogen temperatures. An effective energy barrier to reversal of the magnetization of U eff = 1541 wave number is also measured. The magnetic blocking temperature of T B = 80 kelvin for this cation overcomes an essential barrier toward the development of nanomagnet devices that function at practical temperatures.

    Description: The understanding of natural and sexual selection requires both field and laboratory studies to exploit the advantages and avoid the disadvantages of each approach. However, studies have tended to be polarized among the types of organisms studied, with vertebrates studied in the field and invertebrates in the lab. We used video monitoring combined with DNA profiling of all of the members of a wild population of field crickets across two generations to capture the factors predicting the reproductive success of males and females. The factors that predict a male's success in gaining mates differ from those that predict how many offspring he has. We confirm the fundamental prediction that males vary more in their reproductive success than females, and we find that females as well as males leave more offspring when they mate with more partners.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rodriguez-Munoz, R -- Bretman, A -- Slate, J -- Walling, C A -- Tregenza, T -- New York, N.Y. -- Science. 2010 Jun 4;328(5983):1269-72. doi: 10.1126/science.1188102.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Ecology and Conservation, School of Biosciences, University of Exeter, Cornwall Campus, Penryn TR10 EZ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20522773" target="_blank"〉PubMed〈/a〉

    Description: CD4(+)Foxp3(+) regulatory T (T(reg)) cells are important for maintaining immune tolerance. Understanding the molecular mechanism that regulates T(reg) differentiation will facilitate the development of effective therapeutic strategies against autoimmune diseases. We report here that the SUMO E3 ligase PIAS1 restricts the differentiation of natural T(reg) cells by maintaining a repressive chromatin state of the Foxp3 promoter. PIAS1 acts by binding to the Foxp3 promoter to recruit DNA methyltransferases and heterochromatin protein 1 for epigenetic modifications. Pias1 deletion caused promoter demethylation, reduced histone H3 methylation at Lys(9), and enhanced promoter accessibility. Consistently, Pias1(-/-) mice displayed an increased natural T(reg) cell population and were resistant to the development of experimental autoimmune encephalomyelitis. Our studies have identified an epigenetic mechanism that negatively regulates the differentiation of natural T(reg) cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3043201/" 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/PMC3043201/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Bin -- Tahk, Samuel -- Yee, Kathleen M -- Fan, Guoping -- Shuai, Ke -- K01 AR52717-01/AR/NIAMS NIH HHS/ -- R01 AI063286/AI/NIAID NIH HHS/ -- R01 AI063286-05/AI/NIAID NIH HHS/ -- R01 GM085797/GM/NIGMS NIH HHS/ -- R01 GM085797-03/GM/NIGMS NIH HHS/ -- R01AI063286/AI/NIAID NIH HHS/ -- R01GM085797/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Oct 22;330(6003):521-5. doi: 10.1126/science.1193787.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology-Oncology, Department of Medicine, 11-934 Factor Building, 10833 Le Conte Avenue, University of California, Los Angeles, Los Angeles, CA 90095, USA. bliu@ucla.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20966256" target="_blank"〉PubMed〈/a〉

    Description: Children's reading achievement is influenced by genetics as well as by family and school environments. The importance of teacher quality as a specific school environmental influence on reading achievement is unknown. We studied first- and second-grade students in Florida from schools representing diverse environments. Comparison of monozygotic and dizygotic twins, differentiating genetic similarities of 100% and 50%, provided an estimate of genetic variance in reading achievement. Teacher quality was measured by how much reading gain the non-twin classmates achieved. The magnitude of genetic variance associated with twins' oral reading fluency increased as the quality of their teacher increased. In circumstances where the teachers are all excellent, the variability in student reading achievement may appear to be largely due to genetics. However, poor teaching impedes the ability of children to reach their potential.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2905841/" 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/PMC2905841/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taylor, J -- Roehrig, A D -- Soden Hensler, B -- Connor, C M -- Schatschneider, C -- P50 HD052120/HD/NICHD NIH HHS/ -- P50 HD052120-02/HD/NICHD NIH HHS/ -- P50 HD052120-020003/HD/NICHD NIH HHS/ -- P50 HD052120-030003/HD/NICHD NIH HHS/ -- P50 HD052120-040003/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2010 Apr 23;328(5977):512-4. doi: 10.1126/science.1186149.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Florida State University, Tallahassee, FL 32306-4301, USA. taylor@psy.fsu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20413504" target="_blank"〉PubMed〈/a〉

    Description: Most hosts, including humans, are simultaneously or sequentially infected with several parasites. A key question is whether patterns of coinfection arise because infection by one parasite species affects susceptibility to others or because of inherent differences between hosts. We used time-series data from individual hosts in natural populations to analyze patterns of infection risk for a microparasite community, detecting large positive and negative effects of other infections. Patterns remain once variations in host susceptibility and exposure are accounted for. Indeed, effects are typically of greater magnitude, and explain more variation in infection risk, than the effects associated with host and environmental factors more commonly considered in disease studies. We highlight the danger of mistaken inference when considering parasite species in isolation rather than parasite communities.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3033556/" 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/PMC3033556/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Telfer, Sandra -- Lambin, Xavier -- Birtles, Richard -- Beldomenico, Pablo -- Burthe, Sarah -- Paterson, Steve -- Begon, Mike -- 070675/Z/03/Z/Wellcome Trust/United Kingdom -- 075202/Wellcome Trust/United Kingdom -- 075202/Z/04/Z/Wellcome Trust/United Kingdom -- 081705/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Oct 8;330(6001):243-6. doi: 10.1126/science.1190333.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biological Sciences, University of Liverpool, Crown Street, Liverpool L69 7ZB, UK. s.telfer@abdn.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20929776" target="_blank"〉PubMed〈/a〉

    Description: Gain-of-function mutations in Kir6.2 (KCNJ11), the pore-forming subunit of the adenosine triphosphate (ATP)-sensitive potassium (KATP) channel, cause neonatal diabetes. Many patients also suffer from hypotonia (weak and flaccid muscles) and balance problems. The diabetes arises from suppressed insulin secretion by overactive KATP channels in pancreatic beta-cells, but the source of the motor phenotype is unknown. By using mice carrying a human Kir6.2 mutation (Val59--〉Met59) targeted to either muscle or nerve, we show that analogous motor impairments originate in the central nervous system rather than in muscle or peripheral nerves. We also identify locomotor hyperactivity as a feature of KATP channel overactivity. These findings suggest that drugs targeted against neuronal, rather than muscle, KATP channels are needed to treat the motor deficits and that such drugs require high blood-brain barrier permeability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clark, Rebecca H -- McTaggart, James S -- Webster, Richard -- Mannikko, Roope -- Iberl, Michaela -- Sim, Xiu Li -- Rorsman, Patrik -- Glitsch, Maike -- Beeson, David -- Ashcroft, Frances M -- 084655/Wellcome Trust/United Kingdom -- G0701521/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Jul 23;329(5990):458-61. doi: 10.1126/science.1186146.

    Description: Activation of the EphA2 receptor tyrosine kinase by ephrin-A1 ligands presented on apposed cell surfaces plays important roles in development and exhibits poorly understood functional alterations in cancer. We reconstituted this intermembrane signaling geometry between live EphA2-expressing human breast cancer cells and supported membranes displaying laterally mobile ephrin-A1. Receptor-ligand binding, clustering, and subsequent lateral transport within this junction were observed. EphA2 transport can be blocked by physical barriers nanofabricated onto the underlying substrate. This physical reorganization of EphA2 alters the cellular response to ephrin-A1, as observed by changes in cytoskeleton morphology and recruitment of a disintegrin and metalloprotease 10. Quantitative analysis of receptor-ligand spatial organization across a library of 26 mammary epithelial cell lines reveals characteristic differences that strongly correlate with invasion potential. These observations reveal a mechanism for spatio-mechanical regulation of EphA2 signaling pathways.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2895569/" 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/PMC2895569/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Salaita, Khalid -- Nair, Pradeep M -- Petit, Rebecca S -- Neve, Richard M -- Das, Debopriya -- Gray, Joe W -- Groves, Jay T -- P50 CA 58207/CA/NCI NIH HHS/ -- P50 CA058207/CA/NCI NIH HHS/ -- P50 CA058207-060002/CA/NCI NIH HHS/ -- P50 CA058207-08/CA/NCI NIH HHS/ -- P50 CA058207-09/CA/NCI NIH HHS/ -- U54 CA 112970/CA/NCI NIH HHS/ -- U54 CA112970/CA/NCI NIH HHS/ -- U54 CA112970-01/CA/NCI NIH HHS/ -- U54 CA143836/CA/NCI NIH HHS/ -- U54 CA143836-01/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Mar 12;327(5971):1380-5. doi: 10.1126/science.1181729.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Chemistry, University of California, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20223987" target="_blank"〉PubMed〈/a〉

    Description: Differences in gene expression may play a major role in speciation and phenotypic diversity. We examined genome-wide differences in transcription factor (TF) binding in several humans and a single chimpanzee by using chromatin immunoprecipitation followed by sequencing. The binding sites of RNA polymerase II (PolII) and a key regulator of immune responses, nuclear factor kappaB (p65), were mapped in 10 lymphoblastoid cell lines, and 25 and 7.5% of the respective binding regions were found to differ between individuals. Binding differences were frequently associated with single-nucleotide polymorphisms and genomic structural variants, and these differences were often correlated with differences in gene expression, suggesting functional consequences of binding variation. Furthermore, comparing PolII binding between humans and chimpanzee suggests extensive divergence in TF binding. Our results indicate that many differences in individuals and species occur at the level of TF binding, and they provide insight into the genetic events responsible for these differences.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2938768/" 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/PMC2938768/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kasowski, Maya -- Grubert, Fabian -- Heffelfinger, Christopher -- Hariharan, Manoj -- Asabere, Akwasi -- Waszak, Sebastian M -- Habegger, Lukas -- Rozowsky, Joel -- Shi, Minyi -- Urban, Alexander E -- Hong, Mi-Young -- Karczewski, Konrad J -- Huber, Wolfgang -- Weissman, Sherman M -- Gerstein, Mark B -- Korbel, Jan O -- Snyder, Michael -- R01 CA077808/CA/NCI NIH HHS/ -- R01 CA077808-09/CA/NCI NIH HHS/ -- T32 GM007205/GM/NIGMS NIH HHS/ -- T32 GM007205-34/GM/NIGMS NIH HHS/ -- T32GM07205/GM/NIGMS NIH HHS/ -- U54 HG004558/HG/NHGRI NIH HHS/ -- U54 HG004558-04/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Apr 9;328(5975):232-5. doi: 10.1126/science.1183621.

    Description: Proliferating cells, including cancer cells, require altered metabolism to efficiently incorporate nutrients such as glucose into biomass. The M2 isoform of pyruvate kinase (PKM2) promotes the metabolism of glucose by aerobic glycolysis and contributes to anabolic metabolism. Paradoxically, decreased pyruvate kinase enzyme activity accompanies the expression of PKM2 in rapidly dividing cancer cells and tissues. We demonstrate that phosphoenolpyruvate (PEP), the substrate for pyruvate kinase in cells, can act as a phosphate donor in mammalian cells because PEP participates in the phosphorylation of the glycolytic enzyme phosphoglycerate mutase (PGAM1) in PKM2-expressing cells. We used mass spectrometry to show that the phosphate from PEP is transferred to the catalytic histidine (His11) on human PGAM1. This reaction occurred at physiological concentrations of PEP and produced pyruvate in the absence of PKM2 activity. The presence of histidine-phosphorylated PGAM1 correlated with the expression of PKM2 in cancer cell lines and tumor tissues. Thus, decreased pyruvate kinase activity in PKM2-expressing cells allows PEP-dependent histidine phosphorylation of PGAM1 and may provide an alternate glycolytic pathway that decouples adenosine triphosphate production from PEP-mediated phosphotransfer, allowing for the high rate of glycolysis to support the anabolic metabolism observed in many proliferating cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3030121/" 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/PMC3030121/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vander Heiden, Matthew G -- Locasale, Jason W -- Swanson, Kenneth D -- Sharfi, Hadar -- Heffron, Greg J -- Amador-Noguez, Daniel -- Christofk, Heather R -- Wagner, Gerhard -- Rabinowitz, Joshua D -- Asara, John M -- Cantley, Lewis C -- 1K08CA136983/CA/NCI NIH HHS/ -- 1P01CA120964-01A/CA/NCI NIH HHS/ -- 5 T32 CA009361-28/CA/NCI NIH HHS/ -- 5P30CA006516-43/CA/NCI NIH HHS/ -- K08 CA136983/CA/NCI NIH HHS/ -- K08 CA136983-02/CA/NCI NIH HHS/ -- P01 CA089021/CA/NCI NIH HHS/ -- P01 CA089021-10/CA/NCI NIH HHS/ -- P01 CA120964/CA/NCI NIH HHS/ -- P01 CA120964-01A1/CA/NCI NIH HHS/ -- P01 GM047467/GM/NIGMS NIH HHS/ -- P01 GM047467-20/GM/NIGMS NIH HHS/ -- P01CA089021/CA/NCI NIH HHS/ -- P01GM047467/GM/NIGMS NIH HHS/ -- P30 CA006516/CA/NCI NIH HHS/ -- P30 CA006516-43S1/CA/NCI NIH HHS/ -- R01 AI078063/AI/NIAID NIH HHS/ -- R01 GM056203/GM/NIGMS NIH HHS/ -- R01-GM56302/GM/NIGMS NIH HHS/ -- R21 CA128620/CA/NCI NIH HHS/ -- R21/R33 DK070299/DK/NIDDK NIH HHS/ -- R33 DK070299/DK/NIDDK NIH HHS/ -- R33 DK070299-03/DK/NIDDK NIH HHS/ -- T32 CA009172/CA/NCI NIH HHS/ -- T32 CA009361/CA/NCI NIH HHS/ -- T32 CA009361-28/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 17;329(5998):1492-9. doi: 10.1126/science.1188015.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana Farber Cancer Institute, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20847263" target="_blank"〉PubMed〈/a〉

    Description: Obesity results from chronic energy surplus and excess lipid storage in white adipose tissue (WAT). In contrast, brown adipose tissue (BAT) efficiently burns lipids through adaptive thermogenesis. Studying mouse models, we show that cyclooxygenase (COX)-2, a rate-limiting enzyme in prostaglandin (PG) synthesis, is a downstream effector of beta-adrenergic signaling in WAT and is required for the induction of BAT in WAT depots. PG shifted the differentiation of defined mesenchymal progenitors toward a brown adipocyte phenotype. Overexpression of COX-2 in WAT induced de novo BAT recruitment in WAT, increased systemic energy expenditure, and protected mice against high-fat diet-induced obesity. Thus, COX-2 appears integral to de novo BAT recruitment, which suggests that the PG pathway regulates systemic energy homeostasis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vegiopoulos, Alexandros -- Muller-Decker, Karin -- Strzoda, Daniela -- Schmitt, Iris -- Chichelnitskiy, Evgeny -- Ostertag, Anke -- Berriel Diaz, Mauricio -- Rozman, Jan -- Hrabe de Angelis, Martin -- Nusing, Rolf M -- Meyer, Carola W -- Wahli, Walter -- Klingenspor, Martin -- Herzig, Stephan -- New York, N.Y. -- Science. 2010 May 28;328(5982):1158-61. doi: 10.1126/science.1186034.

    Description: The evolutionary appearance of p53 protein probably preceded its role in tumor suppression, suggesting that there may be unappreciated functions for this protein. Using genetic reporters as proxies to follow in vivo activation of the p53 network in Drosophila, we discovered that the process of meiotic recombination instigates programmed activation of p53 in the germ line. Specifically, double-stranded breaks in DNA generated by the topoisomerase Spo11 provoked functional p53 activity, which was prolonged in cells defective for meiotic DNA repair. This intrinsic stimulus for the p53 regulatory network is highly conserved because Spo11-dependent activation of p53 also occurs in mice. Our findings establish a physiological role for p53 in meiosis and suggest that tumor-suppressive functions may have been co-opted from primordial activities linked to recombination.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2917750/" 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/PMC2917750/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lu, Wan-Jin -- Chapo, Joseph -- Roig, Ignasi -- Abrams, John M -- R01 AA017328/AA/NIAAA NIH HHS/ -- R01 AA017328-03/AA/NIAAA NIH HHS/ -- R01 AA017328-04/AA/NIAAA NIH HHS/ -- R01 GM072124/GM/NIGMS NIH HHS/ -- R01 GM072124-10/GM/NIGMS NIH HHS/ -- R01 GM072124-11/GM/NIGMS NIH HHS/ -- R01 GM072124-12/GM/NIGMS NIH HHS/ -- R01 GM072124-13/GM/NIGMS NIH HHS/ -- R01 GM072124-14A1/GM/NIGMS NIH HHS/ -- R01 GM072124-15/GM/NIGMS NIH HHS/ -- R01 HD040916/HD/NICHD NIH HHS/ -- R01 HD040916-09/HD/NICHD NIH HHS/ -- R01 HD040916-10/HD/NICHD NIH HHS/ -- R01AA017328/AA/NIAAA NIH HHS/ -- R01GM072124/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Jun 4;328(5983):1278-81. doi: 10.1126/science.1185640.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, University of Texas Southwestern Medical Center, Dallas, TX 75390, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20522776" target="_blank"〉PubMed〈/a〉

    Description: All insects in the order Hymenoptera have haplodiploid sex determination, in which males emerge from haploid unfertilized eggs and females are diploid. Sex determination in the honeybee Apis mellifera is controlled by the complementary sex determination (csd) locus, but the mechanisms controlling sex determination in other Hymenoptera without csd are unknown. We identified the sex-determination system of the parasitic wasp Nasonia, which has no csd locus. Instead, maternal input of Nasonia vitripennis transformer (Nvtra) messenger RNA, in combination with specific zygotic Nvtra transcription, in which Nvtra autoregulates female-specific splicing, is essential for female development. Our data indicate that males develop as a result of maternal imprinting that prevents zygotic transcription of the maternally derived Nvtra allele in unfertilized eggs. Upon fertilization, zygotic Nvtra transcription is initiated, which autoregulates the female-specific transcript, leading to female development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Verhulst, Eveline C -- Beukeboom, Leo W -- van de Zande, Louis -- New York, N.Y. -- Science. 2010 Apr 30;328(5978):620-3. doi: 10.1126/science.1185805.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Evolutionary Genetics, Centre for Ecological and Evolutionary Studies, University of Groningen, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20431014" target="_blank"〉PubMed〈/a〉

    Description: Metabolic syndrome is a group of obesity-related metabolic abnormalities that increase an individual's risk of developing type 2 diabetes and cardiovascular disease. Here, we show that mice genetically deficient in Toll-like receptor 5 (TLR5), a component of the innate immune system that is expressed in the gut mucosa and that helps defend against infection, exhibit hyperphagia and develop hallmark features of metabolic syndrome, including hyperlipidemia, hypertension, insulin resistance, and increased adiposity. These metabolic changes correlated with changes in the composition of the gut microbiota, and transfer of the gut microbiota from TLR5-deficient mice to wild-type germ-free mice conferred many features of metabolic syndrome to the recipients. Food restriction prevented obesity, but not insulin resistance, in the TLR5-deficient mice. These results support the emerging view that the gut microbiota contributes to metabolic disease and suggest that malfunction of the innate immune system may promote the development of metabolic syndrome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4714868/" 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/PMC4714868/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vijay-Kumar, Matam -- Aitken, Jesse D -- Carvalho, Frederic A -- Cullender, Tyler C -- Mwangi, Simon -- Srinivasan, Shanthi -- Sitaraman, Shanthi V -- Knight, Rob -- Ley, Ruth E -- Gewirtz, Andrew T -- DK061417/DK/NIDDK NIH HHS/ -- DK06439/DK/NIDDK NIH HHS/ -- DK083275/DK/NIDDK NIH HHS/ -- K01 DK083275/DK/NIDDK NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Apr 9;328(5975):228-31. doi: 10.1126/science.1179721.

    Description: Mammalian meiotic recombination, which preferentially occurs at specialized sites called hotspots, ensures the orderly segregation of meiotic chromosomes and creates genetic variation among offspring. A locus on mouse chromosome 17, which controls activation of recombination at multiple distant hotspots, has been mapped within a 181-kilobase interval, three of whose genes can be eliminated as candidates. The remaining gene, Prdm9, codes for a zinc finger containing histone H3K4 trimethylase that is expressed in early meiosis and whose deficiency results in sterility in both sexes. Mus musculus exhibits five alleles of Prdm9; human populations exhibit two predominant alleles and multiple minor alleles. The identification of Prdm9 as a protein regulating mammalian recombination hotspots initiates molecular studies of this important biological control system.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2821451/" 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/PMC2821451/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parvanov, Emil D -- Petkov, Petko M -- Paigen, Kenneth -- 076468/PHS HHS/ -- 078452/PHS HHS/ -- 083408/PHS HHS/ -- CA 34196/CA/NCI NIH HHS/ -- GM 078643/GM/NIGMS NIH HHS/ -- P30 CA034196-26/CA/NCI NIH HHS/ -- P50 GM076468/GM/NIGMS NIH HHS/ -- P50 GM076468-030004/GM/NIGMS NIH HHS/ -- R01 GM078452/GM/NIGMS NIH HHS/ -- R01 GM078452-02/GM/NIGMS NIH HHS/ -- R01 GM078643/GM/NIGMS NIH HHS/ -- R01 GM078643-03/GM/NIGMS NIH HHS/ -- R01 GM083408/GM/NIGMS NIH HHS/ -- R01 GM083408-02/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Feb 12;327(5967):835. doi: 10.1126/science.1181495.

    Description: When selection favors sexual dimorphism, high-fitness parents often produce low-fitness progeny of the opposite sex. This sexual conflict is thought to overwhelm the genetic benefits of mate choice because preferred males incur a cost through the production of low-fitness daughters. We provide a counterpoint in a lizard (Anolis sagrei) that exhibits sexual conflict over body size. By using mate-choice experiments, we show that female brown anoles produce more sons than daughters via large sires but more daughters than sons via small sires. Measures of progeny fitness in the wild suggest that maximal fitness payoffs can be achieved by shifting offspring production from daughters to sons as sire size increases. These results illustrate how the resolution of sexual conflict can restore the genetic benefits of mate choice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cox, Robert M -- Calsbeek, Ryan -- New York, N.Y. -- Science. 2010 Apr 2;328(5974):92-4. doi: 10.1126/science.1185550.

    Description: Neandertals, the closest evolutionary relatives of present-day humans, lived in large parts of Europe and western Asia before disappearing 30,000 years ago. We present a draft sequence of the Neandertal genome composed of more than 4 billion nucleotides from three individuals. Comparisons of the Neandertal genome to the genomes of five present-day humans from different parts of the world identify a number of genomic regions that may have been affected by positive selection in ancestral modern humans, including genes involved in metabolism and in cognitive and skeletal development. We show that Neandertals shared more genetic variants with present-day humans in Eurasia than with present-day humans in sub-Saharan Africa, suggesting that gene flow from Neandertals into the ancestors of non-Africans occurred before the divergence of Eurasian groups from each other.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Green, Richard E -- Krause, Johannes -- Briggs, Adrian W -- Maricic, Tomislav -- Stenzel, Udo -- Kircher, Martin -- Patterson, Nick -- Li, Heng -- Zhai, Weiwei -- Fritz, Markus Hsi-Yang -- Hansen, Nancy F -- Durand, Eric Y -- Malaspinas, Anna-Sapfo -- Jensen, Jeffrey D -- Marques-Bonet, Tomas -- Alkan, Can -- Prufer, Kay -- Meyer, Matthias -- Burbano, Hernan A -- Good, Jeffrey M -- Schultz, Rigo -- Aximu-Petri, Ayinuer -- Butthof, Anne -- Hober, Barbara -- Hoffner, Barbara -- Siegemund, Madlen -- Weihmann, Antje -- Nusbaum, Chad -- Lander, Eric S -- Russ, Carsten -- Novod, Nathaniel -- Affourtit, Jason -- Egholm, Michael -- Verna, Christine -- Rudan, Pavao -- Brajkovic, Dejana -- Kucan, Zeljko -- Gusic, Ivan -- Doronichev, Vladimir B -- Golovanova, Liubov V -- Lalueza-Fox, Carles -- de la Rasilla, Marco -- Fortea, Javier -- Rosas, Antonio -- Schmitz, Ralf W -- Johnson, Philip L F -- Eichler, Evan E -- Falush, Daniel -- Birney, Ewan -- Mullikin, James C -- Slatkin, Montgomery -- Nielsen, Rasmus -- Kelso, Janet -- Lachmann, Michael -- Reich, David -- Paabo, Svante -- GM40282/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 May 7;328(5979):710-22. doi: 10.1126/science.1188021.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Evolutionary Genetics, Max-Planck Institute for Evolutionary Anthropology, D-04103 Leipzig, Germany. green@eva.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20448178" target="_blank"〉PubMed〈/a〉

    Description: Genomic imprinting results in preferential gene expression from paternally versus maternally inherited chromosomes. We used a genome-wide approach to uncover sex-specific parent-of-origin allelic effects in the adult mouse brain. Our study identified preferential selection of the maternally inherited X chromosome in glutamatergic neurons of the female cortex. Moreover, analysis of the cortex and hypothalamus identified 347 autosomal genes with sex-specific imprinting features. In the hypothalamus, sex-specific imprinted genes were mostly found in females, which suggests parental influence over the hypothalamic function of daughters. We show that interleukin-18, a gene linked to diseases with sex-specific prevalence, is subject to complex, regional, and sex-specific parental effects in the brain. Parent-of-origin effects thus provide new avenues for investigation of sexual dimorphism in brain function and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2997643/" 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/PMC2997643/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gregg, Christopher -- Zhang, Jiangwen -- Butler, James E -- Haig, David -- Dulac, Catherine -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Aug 6;329(5992):682-5. doi: 10.1126/science.1190831.

    Description: Genomic imprinting results in preferential expression of the paternal or maternal allele of certain genes. We have performed a genome-wide characterization of imprinting in the mouse embryonic and adult brain. This approach uncovered parent-of-origin allelic effects of more than 1300 loci. We identified parental bias in the expression of individual genes and of specific transcript isoforms, with differences between brain regions. Many imprinted genes are expressed in neural systems associated with feeding and motivated behaviors, and parental biases preferentially target genetic pathways governing metabolism and cell adhesion. We observed a preferential maternal contribution to gene expression in the developing brain and a major paternal contribution in the adult brain. Thus, parental expression bias emerges as a major mode of epigenetic regulation in the brain.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3005244/" 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/PMC3005244/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gregg, Christopher -- Zhang, Jiangwen -- Weissbourd, Brandon -- Luo, Shujun -- Schroth, Gary P -- Haig, David -- Dulac, Catherine -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Aug 6;329(5992):643-8. doi: 10.1126/science.1190830.

    Description: Hybrids between species are often sterile or inviable because the long-diverged genomes of their parents cause developmental problems when they come together in a single individual. According to the Dobzhansky-Muller (DM) model, the number of genes involved in these "intrinsic postzygotic incompatibilities" should increase faster than linearly with the divergence time between species. This straightforward prediction of the DM model has remained contentious owing to a lack of explicit tests. Examining two pairs of Drosophila species, we show that the number of genes involved in postzygotic isolation increases at least as fast as the square of the number of substitutions (an index of divergence time) between species. This observation verifies a key prediction of the DM model.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matute, Daniel R -- Butler, Ian A -- Turissini, David A -- Coyne, Jerry A -- R01GM058260/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 17;329(5998):1518-21. doi: 10.1126/science.1193440.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, The University of Chicago, 1101 East 57th Street, Chicago, IL 60637, USA. dmatute@uchicago.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20847270" target="_blank"〉PubMed〈/a〉

    Description: Alzheimer's disease is hypothesized to be caused by an imbalance between beta-amyloid (Abeta) production and clearance that leads to Abeta accumulation in the central nervous system (CNS). Abeta production and clearance are key targets in the development of disease-modifying therapeutic agents for Alzheimer's disease. However, there has not been direct evidence of altered Abeta production or clearance in Alzheimer's disease. By using metabolic labeling, we measured Abeta42 and Abeta40 production and clearance rates in the CNS of participants with Alzheimer's disease and cognitively normal controls. Clearance rates for both Abeta42 and Abeta40 were impaired in Alzheimer's disease compared with controls. On average, there were no differences in Abeta40 or Abeta42 production rates. Thus, the common late-onset form of Alzheimer's disease is characterized by an overall impairment in Abeta clearance.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3073454/" 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/PMC3073454/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mawuenyega, Kwasi G -- Sigurdson, Wendy -- Ovod, Vitaliy -- Munsell, Ling -- Kasten, Tom -- Morris, John C -- Yarasheski, Kevin E -- Bateman, Randall J -- K08 AG027091/AG/NIA NIH HHS/ -- K08 AG027091-03/AG/NIA NIH HHS/ -- K23 AG030946/AG/NIA NIH HHS/ -- K23 AG030946-04/AG/NIA NIH HHS/ -- P01 AG003991/AG/NIA NIH HHS/ -- P01 AG003991-28/AG/NIA NIH HHS/ -- P01 AG03991/AG/NIA NIH HHS/ -- P30 DK056341/DK/NIDDK NIH HHS/ -- P30 DK056341-10/DK/NIDDK NIH HHS/ -- P41 GM103422/GM/NIGMS NIH HHS/ -- P41 RR000954/RR/NCRR NIH HHS/ -- P41 RR000954-34/RR/NCRR NIH HHS/ -- P50 AG005681/AG/NIA NIH HHS/ -- P50 AG005681-28/AG/NIA NIH HHS/ -- P50 AG05681/AG/NIA NIH HHS/ -- P60 DK020579/DK/NIDDK NIH HHS/ -- P60 DK020579-31/DK/NIDDK NIH HHS/ -- R01 NS065667/NS/NINDS NIH HHS/ -- R01 NS065667-03/NS/NINDS NIH HHS/ -- UL1 RR024992/RR/NCRR NIH HHS/ -- UL1 RR024992-05/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2010 Dec 24;330(6012):1774. doi: 10.1126/science.1197623.

    Description: The rapid dissemination of the 2009 pandemic influenza virus underscores the need for universal influenza vaccines that elicit protective immunity to diverse viral strains. Here, we show that vaccination with plasmid DNA encoding H1N1 influenza hemagglutinin (HA) and boosting with seasonal vaccine or replication-defective adenovirus 5 vector encoding HA stimulated the production of broadly neutralizing influenza antibodies. This prime/boost combination increased the neutralization of diverse H1N1 strains dating from 1934 to 2007 as compared to either component alone and conferred protection against divergent H1N1 viruses in mice and ferrets. These antibodies were directed to the conserved stem region of HA and were also elicited in nonhuman primates. Cross-neutralization of H1N1 subtypes elicited by this approach provides a basis for the development of a universal influenza vaccine for humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wei, Chih-Jen -- Boyington, Jeffrey C -- McTamney, Patrick M -- Kong, Wing-Pui -- Pearce, Melissa B -- Xu, Ling -- Andersen, Hanne -- Rao, Srinivas -- Tumpey, Terrence M -- Yang, Zhi-Yong -- Nabel, Gary J -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Aug 27;329(5995):1060-4. doi: 10.1126/science.1192517.

    Description: Hamilton's theory of inclusive fitness showed how natural selection could lead to behaviors that decrease the relative fitness of the actor and also either benefit (altruism) or harm (spite) other individuals. However, several fundamental issues in the evolution of altruism and spite have remained contentious. Here, we show how recent work has resolved three key debates, helping clarify how Hamilton's theoretical overview links to real-world examples, in organisms ranging from bacteria to humans: Is the evolution of extreme altruism, represented by the sterile workers of social insects, driven by genetics or ecology? Does spite really exist in nature? And, can altruism be favored between individuals who are not close kin but share a "greenbeard" gene for altruism?〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉West, Stuart A -- Gardner, Andy -- New York, N.Y. -- Science. 2010 Mar 12;327(5971):1341-4. doi: 10.1126/science.1178332.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, Oxford University, South Parks Road, Oxford OX1 3PS, UK. stuart.west@zoo.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20223978" target="_blank"〉PubMed〈/a〉

    Description: Human social interactions crucially depend on the ability to represent other agents' beliefs even when these contradict our own beliefs, leading to the potentially complex problem of simultaneously holding two conflicting representations in mind. Here, we show that adults and 7-month-olds automatically encode others' beliefs, and that, surprisingly, others' beliefs have similar effects as the participants' own beliefs. In a visual object detection task, participants' beliefs and the beliefs of an agent (whose beliefs were irrelevant to performing the task) both modulated adults' reaction times and infants' looking times. Moreover, the agent's beliefs influenced participants' behavior even after the agent had left the scene, suggesting that participants computed the agent's beliefs online and sustained them, possibly for future predictions about the agent's behavior. Hence, the mere presence of an agent automatically triggers powerful processes of belief computation that may be part of a "social sense" crucial to human societies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kovacs, Agnes Melinda -- Teglas, Erno -- Endress, Ansgar Denis -- New York, N.Y. -- Science. 2010 Dec 24;330(6012):1830-4. doi: 10.1126/science.1190792.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Psychology, Hungarian Academy of Sciences, H-1132 Budapest, Hungary. agneskovacs@mtapi.hu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21205671" target="_blank"〉PubMed〈/a〉

    Description: We report here genome sequences and comparative analyses of three closely related parasitoid wasps: Nasonia vitripennis, N. giraulti, and N. longicornis. Parasitoids are important regulators of arthropod populations, including major agricultural pests and disease vectors, and Nasonia is an emerging genetic model, particularly for evolutionary and developmental genetics. Key findings include the identification of a functional DNA methylation tool kit; hymenopteran-specific genes including diverse venoms; lateral gene transfers among Pox viruses, Wolbachia, and Nasonia; and the rapid evolution of genes involved in nuclear-mitochondrial interactions that are implicated in speciation. Newly developed genome resources advance Nasonia for genetic research, accelerate mapping and cloning of quantitative trait loci, and will ultimately provide tools and knowledge for further increasing the utility of parasitoids as pest insect-control agents.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2849982/" 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/PMC2849982/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Werren, John H -- Richards, Stephen -- Desjardins, Christopher A -- Niehuis, Oliver -- Gadau, Jurgen -- Colbourne, John K -- Nasonia Genome Working Group -- Beukeboom, Leo W -- Desplan, Claude -- Elsik, Christine G -- Grimmelikhuijzen, Cornelis J P -- Kitts, Paul -- Lynch, Jeremy A -- Murphy, Terence -- Oliveira, Deodoro C S G -- Smith, Christopher D -- van de Zande, Louis -- Worley, Kim C -- Zdobnov, Evgeny M -- Aerts, Maarten -- Albert, Stefan -- Anaya, Victor H -- Anzola, Juan M -- Barchuk, Angel R -- Behura, Susanta K -- Bera, Agata N -- Berenbaum, May R -- Bertossa, Rinaldo C -- Bitondi, Marcia M G -- Bordenstein, Seth R -- Bork, Peer -- Bornberg-Bauer, Erich -- Brunain, Marleen -- Cazzamali, Giuseppe -- Chaboub, Lesley -- Chacko, Joseph -- Chavez, Dean -- Childers, Christopher P -- Choi, Jeong-Hyeon -- Clark, Michael E -- Claudianos, Charles -- Clinton, Rochelle A -- Cree, Andrew G -- Cristino, Alexandre S -- Dang, Phat M -- Darby, Alistair C -- de Graaf, Dirk C -- Devreese, Bart -- Dinh, Huyen H -- Edwards, Rachel -- Elango, Navin -- Elhaik, Eran -- Ermolaeva, Olga -- Evans, Jay D -- Foret, Sylvain -- Fowler, Gerald R -- Gerlach, Daniel -- Gibson, Joshua D -- Gilbert, Donald G -- Graur, Dan -- Grunder, Stefan -- Hagen, Darren E -- Han, Yi -- Hauser, Frank -- Hultmark, Da -- Hunter, Henry C 4th -- Hurst, Gregory D D -- Jhangian, Shalini N -- Jiang, Huaiyang -- Johnson, Reed M -- Jones, Andrew K -- Junier, Thomas -- Kadowaki, Tatsuhiko -- Kamping, Albert -- Kapustin, Yuri -- Kechavarzi, Bobak -- Kim, Jaebum -- Kim, Jay -- Kiryutin, Boris -- Koevoets, Tosca -- Kovar, Christie L -- Kriventseva, Evgenia V -- Kucharski, Robert -- Lee, Heewook -- Lee, Sandra L -- Lees, Kristin -- Lewis, Lora R -- Loehlin, David W -- Logsdon, John M Jr -- Lopez, Jacqueline A -- Lozado, Ryan J -- Maglott, Donna -- Maleszka, Ryszard -- Mayampurath, Anoop -- Mazur, Danielle J -- McClure, Marcella A -- Moore, Andrew D -- Morgan, Margaret B -- Muller, Jean -- Munoz-Torres, Monica C -- Muzny, Donna M -- Nazareth, Lynne V -- Neupert, Susanne -- Nguyen, Ngoc B -- Nunes, Francis M F -- Oakeshott, John G -- Okwuonu, Geoffrey O -- Pannebakker, Bart A -- Pejaver, Vikas R -- Peng, Zuogang -- Pratt, Stephen C -- Predel, Reinhard -- Pu, Ling-Ling -- Ranson, Hilary -- Raychoudhury, Rhitoban -- Rechtsteiner, Andreas -- Reese, Justin T -- Reid, Jeffrey G -- Riddle, Megan -- Robertson, Hugh M -- Romero-Severson, Jeanne -- Rosenberg, Miriam -- Sackton, Timothy B -- Sattelle, David B -- Schluns, Helge -- Schmitt, Thomas -- Schneider, Martina -- Schuler, Andreas -- Schurko, Andrew M -- Shuker, David M -- Simoes, Zila L P -- Sinha, Saurabh -- Smith, Zachary -- Solovyev, Victor -- Souvorov, Alexandre -- Springauf, Andreas -- Stafflinger, Elisabeth -- Stage, Deborah E -- Stanke, Mario -- Tanaka, Yoshiaki -- Telschow, Arndt -- Trent, Carol -- Vattathil, Selina -- Verhulst, Eveline C -- Viljakainen, Lumi -- Wanner, Kevin W -- Waterhouse, Robert M -- Whitfield, James B -- Wilkes, Timothy E -- Williamson, Michael -- Willis, Judith H -- Wolschin, Florian -- Wyder, Stefan -- Yamada, Takuji -- Yi, Soojin V -- Zecher, Courtney N -- Zhang, Lan -- Gibbs, Richard A -- 5R01GM070026-04/GM/NIGMS NIH HHS/ -- 5R01HG000747-14/HG/NHGRI NIH HHS/ -- 5R24GM084917-02/GM/NIGMS NIH HHS/ -- AI028309-13A2/AI/NIAID NIH HHS/ -- R01 AI055624/AI/NIAID NIH HHS/ -- R01 GM064864/GM/NIGMS NIH HHS/ -- R01 GM064864-04/GM/NIGMS NIH HHS/ -- R01 GM064864-05A2/GM/NIGMS NIH HHS/ -- R01 GM070026/GM/NIGMS NIH HHS/ -- R01 GM070026-04S1/GM/NIGMS NIH HHS/ -- R01 GM079484/GM/NIGMS NIH HHS/ -- R01 GM085163/GM/NIGMS NIH HHS/ -- R01 GM085163-01/GM/NIGMS NIH HHS/ -- R01 GM085233/GM/NIGMS NIH HHS/ -- R01 HG000747/HG/NHGRI NIH HHS/ -- R01 HG000747-14/HG/NHGRI NIH HHS/ -- R01GM064864/GM/NIGMS NIH HHS/ -- R24 GM084917/GM/NIGMS NIH HHS/ -- R24 GM084917-01/GM/NIGMS NIH HHS/ -- R24 GM084917-02/GM/NIGMS NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- U54 HG003273-03/HG/NHGRI NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 15;327(5963):343-8. doi: 10.1126/science.1178028.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20075255" target="_blank"〉PubMed〈/a〉

    Description: Heterozygous somatic mutations in the genes encoding isocitrate dehydrogenase-1 and -2 (IDH1 and IDH2) were recently discovered in human neoplastic disorders. These mutations disable the enzymes' normal ability to convert isocitrate to 2-ketoglutarate (2-KG) and confer on the enzymes a new function: the ability to convert 2-KG to d-2-hydroxyglutarate (D-2-HG). We have detected heterozygous germline mutations in IDH2 that alter enzyme residue Arg(140) in 15 unrelated patients with d-2-hydroxyglutaric aciduria (D-2-HGA), a rare neurometabolic disorder characterized by supraphysiological levels of D-2-HG. These findings provide additional impetus for investigating the role of D-2-HG in the pathophysiology of metabolic disease and cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kranendijk, Martijn -- Struys, Eduard A -- van Schaftingen, Emile -- Gibson, K Michael -- Kanhai, Warsha A -- van der Knaap, Marjo S -- Amiel, Jeanne -- Buist, Neil R -- Das, Anibh M -- de Klerk, Johannis B -- Feigenbaum, Annette S -- Grange, Dorothy K -- Hofstede, Floris C -- Holme, Elisabeth -- Kirk, Edwin P -- Korman, Stanley H -- Morava, Eva -- Morris, Andrew -- Smeitink, Jan -- Sukhai, Ram N -- Vallance, Hilary -- Jakobs, Cornelis -- Salomons, Gajja S -- New York, N.Y. -- Science. 2010 Oct 15;330(6002):336. doi: 10.1126/science.1192632.

    Description: Tumor manipulation of host immunity is important for tumor survival and invasion. Many cancers secrete CCL21, a chemoattractant for various leukocytes and lymphoid tissue inducer cells, which drive lymphoid neogenesis. CCL21 expression by melanoma tumors in mice was associated with an immunotolerant microenvironment, which included the induction of lymphoid-like reticular stromal networks, an altered cytokine milieu, and the recruitment of regulatory leukocyte populations. In contrast, CCL21-deficient tumors induced antigen-specific immunity. CCL21-mediated immune tolerance was dependent on host rather than tumor expression of the CCL21 receptor, CCR7, and could protect distant, coimplanted CCL21-deficient tumors and even nonsyngeneic allografts from rejection. We suggest that by altering the tumor microenvironment, CCL21-secreting tumors shift the host immune response from immunogenic to tolerogenic, which facilitates tumor progression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shields, Jacqueline D -- Kourtis, Iraklis C -- Tomei, Alice A -- Roberts, Joanna M -- Swartz, Melody A -- New York, N.Y. -- Science. 2010 May 7;328(5979):749-52. doi: 10.1126/science.1185837.

    Description: Group functional connectivity magnetic resonance imaging (fcMRI) studies have documented reliable changes in human functional brain maturity over development. Here we show that support vector machine-based multivariate pattern analysis extracts sufficient information from fcMRI data to make accurate predictions about individuals' brain maturity across development. The use of only 5 minutes of resting-state fcMRI data from 238 scans of typically developing volunteers (ages 7 to 30 years) allowed prediction of individual brain maturity as a functional connectivity maturation index. The resultant functional maturation curve accounted for 55% of the sample variance and followed a nonlinear asymptotic growth curve shape. The greatest relative contribution to predicting individual brain maturity was made by the weakening of short-range functional connections between the adult brain's major functional networks.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3135376/" 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/PMC3135376/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dosenbach, Nico U F -- Nardos, Binyam -- Cohen, Alexander L -- Fair, Damien A -- Power, Jonathan D -- Church, Jessica A -- Nelson, Steven M -- Wig, Gagan S -- Vogel, Alecia C -- Lessov-Schlaggar, Christina N -- Barnes, Kelly Anne -- Dubis, Joseph W -- Feczko, Eric -- Coalson, Rebecca S -- Pruett, John R Jr -- Barch, Deanna M -- Petersen, Steven E -- Schlaggar, Bradley L -- DA027046/DA/NIDA NIH HHS/ -- EY16336/EY/NEI NIH HHS/ -- HD057076/HD/NICHD NIH HHS/ -- MH62130/MH/NIMH NIH HHS/ -- NS00169011/NS/NINDS NIH HHS/ -- NS053425/NS/NINDS NIH HHS/ -- NS32979/NS/NINDS NIH HHS/ -- NS41255/NS/NINDS NIH HHS/ -- NS46424/NS/NINDS NIH HHS/ -- NS51281/NS/NINDS NIH HHS/ -- NS55582/NS/NINDS NIH HHS/ -- R01 HD057076/HD/NICHD NIH HHS/ -- R01 HD057076-04/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 10;329(5997):1358-61. doi: 10.1126/science.1194144.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Washington University School of Medicine, St. Louis, MO 63110, USA. ndosenbach@wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20829489" target="_blank"〉PubMed〈/a〉

    Description: The Centre for the AIDS Program of Research in South Africa (CAPRISA) 004 trial assessed the effectiveness and safety of a 1% vaginal gel formulation of tenofovir, a nucleotide reverse transcriptase inhibitor, for the prevention of HIV acquisition in women. A double-blind, randomized controlled trial was conducted comparing tenofovir gel (n = 445 women) with placebo gel (n = 444 women) in sexually active, HIV-uninfected 18- to 40-year-old women in urban and rural KwaZulu-Natal, South Africa. HIV serostatus, safety, sexual behavior, and gel and condom use were assessed at monthly follow-up visits for 30 months. HIV incidence in the tenofovir gel arm was 5.6 per 100 women-years (person time of study observation) (38 out of 680.6 women-years) compared with 9.1 per 100 women-years (60 out of 660.7 women-years) in the placebo gel arm (incidence rate ratio = 0.61; P = 0.017). In high adherers (gel adherence 〉 80%), HIV incidence was 54% lower (P = 0.025) in the tenofovir gel arm. In intermediate adherers (gel adherence 50 to 80%) and low adherers (gel adherence 〈 50%), the HIV incidence reduction was 38 and 28%, respectively. Tenofovir gel reduced HIV acquisition by an estimated 39% overall, and by 54% in women with high gel adherence. No increase in the overall adverse event rates was observed. There were no changes in viral load and no tenofovir resistance in HIV seroconverters. Tenofovir gel could potentially fill an important HIV prevention gap, especially for women unable to successfully negotiate mutual monogamy or condom use.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3001187/" 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/PMC3001187/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abdool Karim, Quarraisha -- Abdool Karim, Salim S -- Frohlich, Janet A -- Grobler, Anneke C -- Baxter, Cheryl -- Mansoor, Leila E -- Kharsany, Ayesha B M -- Sibeko, Sengeziwe -- Mlisana, Koleka P -- Omar, Zaheen -- Gengiah, Tanuja N -- Maarschalk, Silvia -- Arulappan, Natasha -- Mlotshwa, Mukelisiwe -- Morris, Lynn -- Taylor, Douglas -- CAPRISA 004 Trial Group -- AI51794/AI/NIAID NIH HHS/ -- D43 TW000231/TW/FIC NIH HHS/ -- D43 TW000231-17/TW/FIC NIH HHS/ -- D43TW00231/TW/FIC NIH HHS/ -- U01 AI068619/AI/NIAID NIH HHS/ -- U01AI068633/AI/NIAID NIH HHS/ -- U01AI46749/AI/NIAID NIH HHS/ -- U19 AI051794/AI/NIAID NIH HHS/ -- U19 AI051794-05/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 3;329(5996):1168-74. doi: 10.1126/science.1193748.

    Description: Extracellular matrices in diverse biological systems are cross-linked by dityrosine covalent bonds catalyzed by the peroxidase/oxidase system. We show that a peroxidase, secreted by the Anopheles gambiae midgut, and dual oxidase form a dityrosine network that decreases gut permeability to immune elicitors. This network protects the microbiota by preventing activation of epithelial immunity. It also provides a suitable environment for malaria parasites to develop within the midgut lumen without inducing nitric oxide synthase expression. Disruption of this barrier results in strong and effective pathogen-specific immune responses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3510679/" 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/PMC3510679/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kumar, Sanjeev -- Molina-Cruz, Alvaro -- Gupta, Lalita -- Rodrigues, Janneth -- Barillas-Mury, Carolina -- ZIA AI000947-08/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Mar 26;327(5973):1644-8. doi: 10.1126/science.1184008.

    Description: Leukotriene A(4) hydrolase (LTA(4)H) is a proinflammatory enzyme that generates the inflammatory mediator leukotriene B(4) (LTB(4)). LTA(4)H also possesses aminopeptidase activity with unknown substrate and physiological importance; we identified the neutrophil chemoattractant proline-glycine-proline (PGP) as this physiological substrate. PGP is a biomarker for chronic obstructive pulmonary disease (COPD) and is implicated in neutrophil persistence in the lung. In acute neutrophil-driven inflammation, PGP was degraded by LTA(4)H, which facilitated the resolution of inflammation. In contrast, cigarette smoke, a major risk factor for the development of COPD, selectively inhibited LTA(4)H aminopeptidase activity, which led to the accumulation of PGP and neutrophils. These studies imply that therapeutic strategies inhibiting LTA(4)H to prevent LTB(4) generation may not reduce neutrophil recruitment because of elevated levels of PGP.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3072752/" 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/PMC3072752/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Snelgrove, Robert J -- Jackson, Patricia L -- Hardison, Matthew T -- Noerager, Brett D -- Kinloch, Andrew -- Gaggar, Amit -- Shastry, Suresh -- Rowe, Steven M -- Shim, Yun M -- Hussell, Tracy -- Blalock, J Edwin -- 082727/Z/07/Z/Wellcome Trust/United Kingdom -- 1K23DK075788/DK/NIDDK NIH HHS/ -- 1R03DK084110-01/DK/NIDDK NIH HHS/ -- G0400795/Medical Research Council/United Kingdom -- G0802752/Medical Research Council/United Kingdom -- HL07783/HL/NHLBI NIH HHS/ -- HL087824/HL/NHLBI NIH HHS/ -- HL090999/HL/NHLBI NIH HHS/ -- HL102371-A1/HL/NHLBI NIH HHS/ -- K08HL091127/HL/NHLBI NIH HHS/ -- P171/03/C1/048/Medical Research Council/United Kingdom -- P30 DK079337/DK/NIDDK NIH HHS/ -- P30AR050948/AR/NIAMS NIH HHS/ -- P30CA13148/CA/NCI NIH HHS/ -- P50 AT00477/AT/NCCIH NIH HHS/ -- R01 HL077783/HL/NHLBI NIH HHS/ -- R01 HL077783-05/HL/NHLBI NIH HHS/ -- R01 HL087824/HL/NHLBI NIH HHS/ -- R01 HL087824-02/HL/NHLBI NIH HHS/ -- R01 HL090999/HL/NHLBI NIH HHS/ -- R01 HL090999-02S1/HL/NHLBI NIH HHS/ -- R01 HL090999-04/HL/NHLBI NIH HHS/ -- R01 HL102371/HL/NHLBI NIH HHS/ -- RR19231/RR/NCRR NIH HHS/ -- U54CA100949/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2010 Oct 1;330(6000):90-4. doi: 10.1126/science.1190594.

    Description: The evolution of family life has traditionally been studied in parallel by behavioral ecologists and quantitative geneticists. The former focus on parent-offspring conflict and whether parents or offspring control provisioning, whereas the latter concentrate on the coadaptation of parental supply and offspring demand. Here we show how prenatal effects on offspring begging can link the two different approaches. Using theoretical and experimental analyses, we show that when offspring control provisioning, prenatal effects primarily serve the parent's interests: Selection on parents drives coadaptation of parent and offspring traits. In contrast, when parents control provisioning, prenatal effects primarily serve the offspring's interests: Selection on the offspring drives coadaptation of parent and offspring traits. Parent-offspring conflict may thus be responsible for the selective forces that generate parent-offspring coadaptation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hinde, Camilla A -- Johnstone, Rufus A -- Kilner, Rebecca M -- New York, N.Y. -- Science. 2010 Mar 12;327(5971):1373-6. doi: 10.1126/science.1186056.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Cambridge, Downing Street, Cambridge CB2 3EJ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20223985" target="_blank"〉PubMed〈/a〉

    Description: Queens of ants and bees normally obtain a lifetime supply of sperm on a single day of sexual activity, and sperm competition is expected to occur in lineages where queens receive sperm from multiple males. We compared singly mated (monandrous) and multiply mated (polyandrous) sister groups of ants and bees and show that seminal fluid of polyandrous species has a more positive effect on the survival of a male's own sperm than on other males' sperm. This difference was not observed in the monandrous species, suggesting that incapacitation of competing sperm may have independently evolved in both bees and ants. In Atta leafcutter ants, the negative effect of the seminal fluid of other males was negated by secretion from the queen sperm-storage organ, suggesting that queens may control ejaculate competition after sperm storage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉den Boer, Susanne P A -- Baer, Boris -- Boomsma, Jacobus J -- New York, N.Y. -- Science. 2010 Mar 19;327(5972):1506-9. doi: 10.1126/science.1184709.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Social Evolution, Department of Biology, University of Copenhagen, Universitetsparken 15, 2100 Copenhagen, Denmark.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20299595" target="_blank"〉PubMed〈/a〉

    Description: The prion hypothesis posits that a misfolded form of prion protein (PrP) is responsible for the infectivity of prion disease. Using recombinant murine PrP purified from Escherichia coli, we created a recombinant prion with the attributes of the pathogenic PrP isoform: aggregated, protease-resistant, and self-perpetuating. After intracerebral injection of the recombinant prion, wild-type mice developed neurological signs in approximately 130 days and reached the terminal stage of disease in approximately 150 days. Characterization of diseased mice revealed classic neuropathology of prion disease, the presence of protease-resistant PrP, and the capability of serially transmitting the disease; these findings confirmed that the mice succumbed to prion disease. Thus, as postulated by the prion hypothesis, the infectivity in mammalian prion disease results from an altered conformation of PrP.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2893558/" 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/PMC2893558/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Fei -- Wang, Xinhe -- Yuan, Chong-Gang -- Ma, Jiyan -- R01 NS060729/NS/NINDS NIH HHS/ -- R01 NS060729-01A1/NS/NINDS NIH HHS/ -- R01NS060729/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2010 Feb 26;327(5969):1132-5. doi: 10.1126/science.1183748.

    Description: Genetic crosses in many organisms have shown that alleles of unlinked genes generally assort independently of one another during gamete formation. However, variation in chromosome size may affect the process of meiosis and lead to nonindependent assortment of chromosomes. We therefore examined chromosomes with insertions and found that they preferentially segregated away from the X chromosome during meiosis in Caenorhabditis elegans males. Conversely, chromosomes with deletions preferentially segregated with the X chromosome. The degree of segregation bias was significantly associated with the length of the insertion or deletion. Simulations revealed that this segregation bias leads to genome size reduction in hermaphroditic species, a pattern consistent with differences in genome sizes in the genus Caenorhabditis. These results suggest that insertions and deletions may affect chromosome segregation patterns.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, John -- Chen, Pei-Jiun -- Wang, George J -- Keller, Laurent -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Jul 16;329(5989):293. doi: 10.1126/science.1190130.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, University of Lausanne, CH-1015 Lausanne, Switzerland.

    Description: Dopamine (DA) has long been implicated in impulsivity, but the precise mechanisms linking human variability in DA signaling to differences in impulsive traits remain largely unknown. By using a dual-scan positron emission tomography approach in healthy human volunteers with amphetamine and the D2/D3 ligand [18F]fallypride, we found that higher levels of trait impulsivity were predicted by diminished midbrain D2/D3 autoreceptor binding and greater amphetamine-induced DA release in the striatum, which was in turn associated with stimulant craving. Path analysis confirmed that the impact of decreased midbrain D2/D3 autoreceptor availability on trait impulsivity is mediated in part through its effect on stimulated striatal DA release.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3161413/" 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/PMC3161413/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Buckholtz, Joshua W -- Treadway, Michael T -- Cowan, Ronald L -- Woodward, Neil D -- Li, Rui -- Ansari, M Sib -- Baldwin, Ronald M -- Schwartzman, Ashley N -- Shelby, Evan S -- Smith, Clarence E -- Kessler, Robert M -- Zald, David H -- R01 DA019670/DA/NIDA NIH HHS/ -- R01 DA019670-04/DA/NIDA NIH HHS/ -- R01DA019670-04/DA/NIDA NIH HHS/ -- T32 MH018921/MH/NIMH NIH HHS/ -- T32 MH018921-22/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2010 Jul 30;329(5991):532. doi: 10.1126/science.1185778.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Vanderbilt University, Nashville, TN 37240, USA. joshua.buckholtz@vanderbilt.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20671181" target="_blank"〉PubMed〈/a〉

    Description: Touch is both the first sense to develop and a critical means of information acquisition and environmental manipulation. Physical touch experiences may create an ontological scaffold for the development of intrapersonal and interpersonal conceptual and metaphorical knowledge, as well as a springboard for the application of this knowledge. In six experiments, holding heavy or light clipboards, solving rough or smooth puzzles, and touching hard or soft objects nonconsciously influenced impressions and decisions formed about unrelated people and situations. Among other effects, heavy objects made job candidates appear more important, rough objects made social interactions appear more difficult, and hard objects increased rigidity in negotiations. Basic tactile sensations are thus shown to influence higher social cognitive processing in dimension-specific and metaphor-specific ways.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3005631/" 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/PMC3005631/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ackerman, Joshua M -- Nocera, Christopher C -- Bargh, John A -- MH60767/MH/NIMH NIH HHS/ -- R01 MH060767-10/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2010 Jun 25;328(5986):1712-5. doi: 10.1126/science.1189993.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sloan School of Management, Massachusetts Institute of Technology, 77 Massachusetts Avenue, E62, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20576894" target="_blank"〉PubMed〈/a〉

    Description: Tibetans have lived at very high altitudes for thousands of years, and they have a distinctive suite of physiological traits that enable them to tolerate environmental hypoxia. These phenotypes are clearly the result of adaptation to this environment, but their genetic basis remains unknown. We report genome-wide scans that reveal positive selection in several regions that contain genes whose products are likely involved in high-altitude adaptation. Positively selected haplotypes of EGLN1 and PPARA were significantly associated with the decreased hemoglobin phenotype that is unique to this highland population. Identification of these genes provides support for previously hypothesized mechanisms of high-altitude adaptation and illuminates the complexity of hypoxia-response pathways in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Simonson, Tatum S -- Yang, Yingzhong -- Huff, Chad D -- Yun, Haixia -- Qin, Ga -- Witherspoon, David J -- Bai, Zhenzhong -- Lorenzo, Felipe R -- Xing, Jinchuan -- Jorde, Lynn B -- Prchal, Josef T -- Ge, RiLi -- 1P01CA108671-01A2/CA/NCI NIH HHS/ -- DK069513/DK/NIDDK NIH HHS/ -- GM059290/GM/NIGMS NIH HHS/ -- HL50077/HL/NHLBI NIH HHS/ -- R00 HG005846/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2010 Jul 2;329(5987):72-5. doi: 10.1126/science.1189406.

    Description: Mirror movements are involuntary contralateral movements that mirror voluntary ones and are often associated with defects in midline crossing of the developing central nervous system. We studied two large families, one French Canadian and one Iranian, in which isolated congenital mirror movements were inherited as an autosomal dominant trait. We found that affected individuals carried protein-truncating mutations in DCC (deleted in colorectal carcinoma), a gene on chromosome 18q21.2 that encodes a receptor for netrin-1, a diffusible protein that helps guide axon growth across the midline. Functional analysis of the mutant DCC protein from the French Canadian family revealed a defect in netrin-1 binding. Thus, DCC has an important role in lateralization of the human nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Srour, Myriam -- Riviere, Jean-Baptiste -- Pham, Jessica M T -- Dube, Marie-Pierre -- Girard, Simon -- Morin, Steves -- Dion, Patrick A -- Asselin, Geraldine -- Rochefort, Daniel -- Hince, Pascale -- Diab, Sabrina -- Sharafaddinzadeh, Naser -- Chouinard, Sylvain -- Theoret, Hugo -- Charron, Frederic -- Rouleau, Guy A -- New York, N.Y. -- Science. 2010 Apr 30;328(5978):592. doi: 10.1126/science.1186463.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center of Excellence in Neuromics, Universite de Montreal, Montreal, QC H2L 2W5, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20431009" target="_blank"〉PubMed〈/a〉

    Description: The intracerebral injection of beta-amyloid-containing brain extracts can induce cerebral beta-amyloidosis and associated pathologies in susceptible hosts.

    Description: Intracellular bacterial pathogens, such as Listeria monocytogenes, are detected in the cytosol of host immune cells. Induction of this host response is often dependent on microbial secretion systems and, in L. monocytogenes, is dependent on multidrug efflux pumps (MDRs). Using L. monocytogenes mutants that overexpressed MDRs, we identified cyclic diadenosine monophosphate (c-di-AMP) as a secreted molecule able to trigger the cytosolic host response. Overexpression of the di-adenylate cyclase, dacA (lmo2120), resulted in elevated levels of the host response during infection. c-di-AMP thus represents a putative bacterial secondary signaling molecule that triggers a cytosolic pathway of innate immunity and is predicted to be present in a wide variety of bacteria and archea.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3156580/" 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/PMC3156580/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Woodward, Joshua J -- Iavarone, Anthony T -- Portnoy, Daniel A -- P01 AI063302/AI/NIAID NIH HHS/ -- P01 AI063302-03/AI/NIAID NIH HHS/ -- T32 CA 009179/CA/NCI NIH HHS/ -- T32 CA009179/CA/NCI NIH HHS/ -- T32 CA009179-35/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2010 Jun 25;328(5986):1703-5. doi: 10.1126/science.1189801.

    Description: The anterior prefrontal cortex (APC) confers on humans the ability to simultaneously pursue several goals. How does the brain's motivational system, including the medial frontal cortex (MFC), drive the pursuit of concurrent goals? Using brain imaging, we observed that the left and right MFC, which jointly drive single-task performance according to expected rewards, divide under dual-task conditions: While the left MFC encodes the rewards driving one task, the right MFC concurrently encodes those driving the other task. The same dichotomy was observed in the lateral frontal cortex, whereas the APC combined the rewards driving both tasks. The two frontal lobes thus divide for representing simultaneously two concurrent goals coordinated by the APC. The human frontal function seems limited to driving the pursuit of two concurrent goals simultaneously.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Charron, Sylvain -- Koechlin, Etienne -- New York, N.Y. -- Science. 2010 Apr 16;328(5976):360-3. doi: 10.1126/science.1183614.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut National de la Sante et de la Recherche Medicale, Paris F-75654 Cedex 13, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20395509" target="_blank"〉PubMed〈/a〉

    Description: Most firefly species (Coleoptera: Lampyridae) use bioluminescent flashes for signaling. In some species, the flashing between males occurs rhythmically and repeatedly (synchronically) with millisecond precision. We studied synchrony's behavioral role in the North American firefly, Photinus carolinus. We placed a female in a virtual environment containing artificial males that flashed at varying degrees of synchrony. Females responded to an average of 82% of synchronous flashes compared with as few as 3% of asynchronous flashes. We conclude that one function of flash synchrony is to facilitate a female's ability to recognize her conspecific male's flashing by eliminating potential visual clutter from other flashing males.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moiseff, Andrew -- Copeland, Jonathan -- New York, N.Y. -- Science. 2010 Jul 9;329(5988):181. doi: 10.1126/science.1190421.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology and Neurobiology, University of Connecticut, Storrs, CT 06269, USA.
