    Description: There has been a massive increase in recent years of the use of lead (Pb) isotopes in attempts to better understand sources and pathways of Pb in the environment and in man or experimental animals. Unfortunately, there have been many cases where the quality of the isotopic data, especially that obtained by quadrupole inductively coupled plasma mass spectrometry (Q-ICP-MS), are questionable, resulting in questionable identification of potential sources, which, in turn, impacts study interpretation and conclusions. We present several cases where the isotopic data have compromised interpretation because of the use of only the major isotopes 208Pb/206Pb and 207Pb/206Pb, or their graphing in other combinations. We also present some examples comparing high precision data from thermal ionization (TIMS) or multi-collector plasma mass spectrometry (MC-ICP-MS) to illustrate the deficiency in the Q-ICP-MS data. In addition, we present cases where Pb isotopic ratios measured on Q-ICP-MS are virtually impossible for terrestrial samples. We also evaluate the Pb isotopic data for rat studies, which had concluded that Pb isotopic fractionation occurs between different organs and suggest that this notion of biological fractionation of Pb as an explanation for isotopic differences is not valid. Overall, the brief review of these case studies shows that Q-ICP-MS as commonly practiced is not a suitable technique for precise and accurate Pb isotopic analysis in the environment and health fields

    Description: Contemporary Jews comprise an aggregate of ethno-religious communities whose worldwide members identify with each other through various shared religious, historical and cultural traditions. Historical evidence suggests common origins in the Middle East, followed by migrations leading to the establishment of communities of Jews in Europe, Africa and Asia, in what is termed the Jewish Diaspora. This complex demographic history imposes special challenges in attempting to address the genetic structure of the Jewish people. Although many genetic studies have shed light on Jewish origins and on diseases prevalent among Jewish communities, including studies focusing on uniparentally and biparentally inherited markers, genome-wide patterns of variation across the vast geographic span of Jewish Diaspora communities and their respective neighbours have yet to be addressed. Here we use high-density bead arrays to genotype individuals from 14 Jewish Diaspora communities and compare these patterns of genome-wide diversity with those from 69 Old World non-Jewish populations, of which 25 have not previously been reported. These samples were carefully chosen to provide comprehensive comparisons between Jewish and non-Jewish populations in the Diaspora, as well as with non-Jewish populations from the Middle East and north Africa. Principal component and structure-like analyses identify previously unrecognized genetic substructure within the Middle East. Most Jewish samples form a remarkably tight subcluster that overlies Druze and Cypriot samples but not samples from other Levantine populations or paired Diaspora host populations. In contrast, Ethiopian Jews (Beta Israel) and Indian Jews (Bene Israel and Cochini) cluster with neighbouring autochthonous populations in Ethiopia and western India, respectively, despite a clear paternal link between the Bene Israel and the Levant. These results cast light on the variegated genetic architecture of the Middle East, and trace the origins of most Jewish Diaspora communities to the Levant.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Behar, Doron M -- Yunusbayev, Bayazit -- Metspalu, Mait -- Metspalu, Ene -- Rosset, Saharon -- Parik, Juri -- Rootsi, Siiri -- Chaubey, Gyaneshwer -- Kutuev, Ildus -- Yudkovsky, Guennady -- Khusnutdinova, Elza K -- Balanovsky, Oleg -- Semino, Ornella -- Pereira, Luisa -- Comas, David -- Gurwitz, David -- Bonne-Tamir, Batsheva -- Parfitt, Tudor -- Hammer, Michael F -- Skorecki, Karl -- Villems, Richard -- England -- Nature. 2010 Jul 8;466(7303):238-42. doi: 10.1038/nature09103.

    Description: The pre-T-cell antigen receptor (pre-TCR), expressed by immature thymocytes, has a pivotal role in early T-cell development, including TCR beta-selection, survival and proliferation of CD4(-)CD8(-) double-negative thymocytes, and subsequent alphabeta T-cell lineage differentiation. Whereas alphabetaTCR ligation by the peptide-loaded major histocompatibility complex initiates T-cell signalling, pre-TCR-induced signalling occurs by means of a ligand-independent dimerization event. The pre-TCR comprises an invariant alpha-chain (pre-Talpha) that pairs with any TCR beta-chain (TCRbeta) following successful TCR beta-gene rearrangement. Here we provide the basis of pre-Talpha-TCRbeta assembly and pre-TCR dimerization. The pre-Talpha chain comprised a single immunoglobulin-like domain that is structurally distinct from the constant (C) domain of the TCR alpha-chain; nevertheless, the mode of association between pre-Talpha and TCRbeta mirrored that mediated by the Calpha-Cbeta domains of the alphabetaTCR. The pre-TCR had a propensity to dimerize in solution, and the molecular envelope of the pre-TCR dimer correlated well with the observed head-to-tail pre-TCR dimer. This mode of pre-TCR dimerization enabled the pre-Talpha domain to interact with the variable (V) beta domain through residues that are highly conserved across the Vbeta and joining (J) beta gene families, thus mimicking the interactions at the core of the alphabetaTCR's Valpha-Vbeta interface. Disruption of this pre-Talpha-Vbeta dimer interface abrogated pre-TCR dimerization in solution and impaired pre-TCR expression on the cell surface. Accordingly, we provide a mechanism of pre-TCR self-association that allows the pre-Talpha chain to simultaneously 'sample' the correct folding of both the V and C domains of any TCR beta-chain, regardless of its ultimate specificity, which represents a critical checkpoint in T-cell development. This unusual dual-chaperone-like sensing function of pre-Talpha represents a unique mechanism in nature whereby developmental quality control regulates the expression and signalling of an integral membrane receptor complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pang, Siew Siew -- Berry, Richard -- Chen, Zhenjun -- Kjer-Nielsen, Lars -- Perugini, Matthew A -- King, Glenn F -- Wang, Christina -- Chew, Sock Hui -- La Gruta, Nicole L -- Williams, Neal K -- Beddoe, Travis -- Tiganis, Tony -- Cowieson, Nathan P -- Godfrey, Dale I -- Purcell, Anthony W -- Wilce, Matthew C J -- McCluskey, James -- Rossjohn, Jamie -- England -- Nature. 2010 Oct 14;467(7317):844-8. doi: 10.1038/nature09448.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Protein Crystallography Unit, Department of Biochemistry and Molecular Biology, School of Biomedical Sciences, Monash University, Clayton, Victoria 3800, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20944746" target="_blank"〉PubMed〈/a〉

    Description: Humans have engaged in endurance running for millions of years, but the modern running shoe was not invented until the 1970s. For most of human evolutionary history, runners were either barefoot or wore minimal footwear such as sandals or moccasins with smaller heels and little cushioning relative to modern running shoes. We wondered how runners coped with the impact caused by the foot colliding with the ground before the invention of the modern shoe. Here we show that habitually barefoot endurance runners often land on the fore-foot (fore-foot strike) before bringing down the heel, but they sometimes land with a flat foot (mid-foot strike) or, less often, on the heel (rear-foot strike). In contrast, habitually shod runners mostly rear-foot strike, facilitated by the elevated and cushioned heel of the modern running shoe. Kinematic and kinetic analyses show that even on hard surfaces, barefoot runners who fore-foot strike generate smaller collision forces than shod rear-foot strikers. This difference results primarily from a more plantarflexed foot at landing and more ankle compliance during impact, decreasing the effective mass of the body that collides with the ground. Fore-foot- and mid-foot-strike gaits were probably more common when humans ran barefoot or in minimal shoes, and may protect the feet and lower limbs from some of the impact-related injuries now experienced by a high percentage of runners.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lieberman, Daniel E -- Venkadesan, Madhusudhan -- Werbel, William A -- Daoud, Adam I -- D'Andrea, Susan -- Davis, Irene S -- Mang'eni, Robert Ojiambo -- Pitsiladis, Yannis -- England -- Nature. 2010 Jan 28;463(7280):531-5. doi: 10.1038/nature08723.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Human Evolutionary Biology, 11 Divinity Avenue, Harvard University, Cambridge, Massachusetts 02138, USA. danlieb@fas.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20111000" target="_blank"〉PubMed〈/a〉

    Description: E1 enzymes activate ubiquitin (Ub) and ubiquitin-like (Ubl) proteins in two steps by carboxy-terminal adenylation and thioester bond formation to a conserved catalytic cysteine in the E1 Cys domain. The structural basis for these intermediates remains unknown. Here we report crystal structures for human SUMO E1 in complex with SUMO adenylate and tetrahedral intermediate analogues at 2.45 and 2.6 A, respectively. These structures show that side chain contacts to ATP.Mg are released after adenylation to facilitate a 130 degree rotation of the Cys domain during thioester bond formation that is accompanied by remodelling of key structural elements including the helix that contains the E1 catalytic cysteine, the crossover and re-entry loops, and refolding of two helices that are required for adenylation. These changes displace side chains required for adenylation with side chains required for thioester bond formation. Mutational and biochemical analyses indicate these mechanisms are conserved in other E1s.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2866016/" 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/PMC2866016/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olsen, Shaun K -- Capili, Allan D -- Lu, Xuequan -- Tan, Derek S -- Lima, Christopher D -- F32 GM075695/GM/NIGMS NIH HHS/ -- F32 GM075695-03/GM/NIGMS NIH HHS/ -- R01 AI068038/AI/NIAID NIH HHS/ -- R01 AI068038-02/AI/NIAID NIH HHS/ -- R01 AI068038-03/AI/NIAID NIH HHS/ -- R01 GM065872/GM/NIGMS NIH HHS/ -- R01 GM065872-09/GM/NIGMS NIH HHS/ -- RR-15301/RR/NCRR NIH HHS/ -- England -- Nature. 2010 Feb 18;463(7283):906-12. doi: 10.1038/nature08765.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Structural Biology, Sloan-Kettering Institute, New York, New York 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20164921" target="_blank"〉PubMed〈/a〉

    Description: MyD88, IRAK4 and IRAK2 are critical signalling mediators of the TLR/IL1-R superfamily. Here we report the crystal structure of the MyD88-IRAK4-IRAK2 death domain (DD) complex, which surprisingly reveals a left-handed helical oligomer that consists of 6 MyD88, 4 IRAK4 and 4 IRAK2 DDs. Assembly of this helical signalling tower is hierarchical, in which MyD88 recruits IRAK4 and the MyD88-IRAK4 complex recruits the IRAK4 substrates IRAK2 or the related IRAK1. Formation of these Myddosome complexes brings the kinase domains of IRAKs into proximity for phosphorylation and activation. Composite binding sites are required for recruitment of the individual DDs in the complex, which are confirmed by mutagenesis and previously identified signalling mutations. Specificities in Myddosome formation are dictated by both molecular complementarity and correspondence of surface electrostatics. The MyD88-IRAK4-IRAK2 complex provides a template for Toll signalling in Drosophila and an elegant mechanism for versatile assembly and regulation of DD complexes in signal transduction.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2888693/" 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/PMC2888693/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Su-Chang -- Lo, Yu-Chih -- Wu, Hao -- P30 EB009998/EB/NIBIB NIH HHS/ -- R01 AI050872/AI/NIAID NIH HHS/ -- R01 AI050872-09/AI/NIAID NIH HHS/ -- England -- Nature. 2010 Jun 17;465(7300):885-90. doi: 10.1038/nature09121.

    Description: Polycomb group (PcG) proteins are transcriptional repressors that control processes ranging from the maintenance of cell fate decisions and stem cell pluripotency in animals to the control of flowering time in plants. In Drosophila, genetic studies identified more than 15 different PcG proteins that are required to repress homeotic (HOX) and other developmental regulator genes in cells where they must stay inactive. Biochemical analyses established that these PcG proteins exist in distinct multiprotein complexes that bind to and modify chromatin of target genes. Among those, Polycomb repressive complex 1 (PRC1) and the related dRing-associated factors (dRAF) complex contain an E3 ligase activity for monoubiquitination of histone H2A (refs 1-4). Here we show that the uncharacterized Drosophila PcG gene calypso encodes the ubiquitin carboxy-terminal hydrolase BAP1. Biochemically purified Calypso exists in a complex with the PcG protein ASX, and this complex, named Polycomb repressive deubiquitinase (PR-DUB), is bound at PcG target genes in Drosophila. Reconstituted recombinant Drosophila and human PR-DUB complexes remove monoubiquitin from H2A but not from H2B in nucleosomes. Drosophila mutants lacking PR-DUB show a strong increase in the levels of monoubiquitinated H2A. A mutation that disrupts the catalytic activity of Calypso, or absence of the ASX subunit abolishes H2A deubiquitination in vitro and HOX gene repression in vivo. Polycomb gene silencing may thus entail a dynamic balance between H2A ubiquitination by PRC1 and dRAF, and H2A deubiquitination by PR-DUB.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3182123/" 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/PMC3182123/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scheuermann, Johanna C -- de Ayala Alonso, Andres Gaytan -- Oktaba, Katarzyna -- Ly-Hartig, Nga -- McGinty, Robert K -- Fraterman, Sven -- Wilm, Matthias -- Muir, Tom W -- Muller, Jurg -- R01 GM086868/GM/NIGMS NIH HHS/ -- R01 GM086868-13/GM/NIGMS NIH HHS/ -- RC2 CA148354/CA/NCI NIH HHS/ -- RC2 CA148354-02/CA/NCI NIH HHS/ -- RC2CA148354/CA/NCI NIH HHS/ -- England -- Nature. 2010 May 13;465(7295):243-7. doi: 10.1038/nature08966.

    Description: Chronic myelogenous leukaemia (CML) can progress from a slow growing chronic phase to an aggressive blast crisis phase, but the molecular basis of this transition remains poorly understood. Here we have used mouse models of CML to show that disease progression is regulated by the Musashi-Numb signalling axis. Specifically, we find that the chronic phase is marked by high levels of Numb expression whereas the blast crisis phase has low levels of Numb expression, and that ectopic expression of Numb promotes differentiation and impairs advanced-phase disease in vivo. As a possible explanation for the decreased levels of Numb in the blast crisis phase, we show that NUP98-HOXA9, an oncogene associated with blast crisis CML, can trigger expression of the RNA-binding protein Musashi2 (Msi2), which in turn represses Numb. Notably, loss of Msi2 restores Numb expression and significantly impairs the development and propagation of blast crisis CML in vitro and in vivo. Finally we show that Msi2 expression is not only highly upregulated during human CML progression but is also an early indicator of poorer prognosis. These data show that the Musashi-Numb pathway can control the differentiation of CML cells, and raise the possibility that targeting this pathway may provide a new strategy for the therapy of aggressive leukaemias.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2918284/" 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/PMC2918284/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ito, Takahiro -- Kwon, Hyog Young -- Zimdahl, Bryan -- Congdon, Kendra L -- Blum, Jordan -- Lento, William E -- Zhao, Chen -- Lagoo, Anand -- Gerrard, Gareth -- Foroni, Letizia -- Goldman, John -- Goh, Harriet -- Kim, Soo-Hyun -- Kim, Dong-Wook -- Chuah, Charles -- Oehler, Vivian G -- Radich, Jerald P -- Jordan, Craig T -- Reya, Tannishtha -- AI067798/AI/NIAID NIH HHS/ -- CA122206/CA/NCI NIH HHS/ -- CA140371/CA/NCI NIH HHS/ -- CA18029/CA/NCI NIH HHS/ -- DK072234/DK/NIDDK NIH HHS/ -- DK63031/DK/NIDDK NIH HHS/ -- DP1 CA174422/CA/NCI NIH HHS/ -- DP1 OD006430/OD/NIH HHS/ -- DP1 OD006430-01/OD/NIH HHS/ -- DP1 OD006430-02/OD/NIH HHS/ -- DP1OD006430/OD/NIH HHS/ -- HL097767/HL/NHLBI NIH HHS/ -- P01 CA018029/CA/NCI NIH HHS/ -- R01 CA140371/CA/NCI NIH HHS/ -- R01 DK063031/DK/NIDDK NIH HHS/ -- R01 DK063031-01/DK/NIDDK NIH HHS/ -- R01 DK063031-01S1/DK/NIDDK NIH HHS/ -- R01 DK063031-02/DK/NIDDK NIH HHS/ -- R01 DK063031-03/DK/NIDDK NIH HHS/ -- R01 DK063031-04/DK/NIDDK NIH HHS/ -- R01 DK063031-05/DK/NIDDK NIH HHS/ -- R01 DK063031-06/DK/NIDDK NIH HHS/ -- R01 DK063031-07/DK/NIDDK NIH HHS/ -- R01 DK063031-07S1/DK/NIDDK NIH HHS/ -- R01 DK063031-08/DK/NIDDK NIH HHS/ -- R01 DK072234/DK/NIDDK NIH HHS/ -- R01 DK072234-01A1/DK/NIDDK NIH HHS/ -- R01 DK072234-02/DK/NIDDK NIH HHS/ -- R01 DK072234-03/DK/NIDDK NIH HHS/ -- R01 DK072234-04/DK/NIDDK NIH HHS/ -- R01 HL097767/HL/NHLBI NIH HHS/ -- R01 HL097767-01/HL/NHLBI NIH HHS/ -- R01 HL097767-02/HL/NHLBI NIH HHS/ -- T32 GM007184-33/GM/NIGMS NIH HHS/ -- U19 AI067798/AI/NIAID NIH HHS/ -- U19 AI067798-010006/AI/NIAID NIH HHS/ -- U19 AI067798-020006/AI/NIAID NIH HHS/ -- U19 AI067798-030006/AI/NIAID NIH HHS/ -- U19 AI067798-040006/AI/NIAID NIH HHS/ -- U19 AI067798-050006/AI/NIAID NIH HHS/ -- England -- Nature. 2010 Aug 5;466(7307):765-8. doi: 10.1038/nature09171.

    Description: Malaria is a devastating infection caused by protozoa of the genus Plasmodium. Drug resistance is widespread, no new chemical class of antimalarials has been introduced into clinical practice since 1996 and there is a recent rise of parasite strains with reduced sensitivity to the newest drugs. We screened nearly 2 million compounds in GlaxoSmithKline's chemical library for inhibitors of P. falciparum, of which 13,533 were confirmed to inhibit parasite growth by at least 80% at 2 microM concentration. More than 8,000 also showed potent activity against the multidrug resistant strain Dd2. Most (82%) compounds originate from internal company projects and are new to the malaria community. Analyses using historic assay data suggest several novel mechanisms of antimalarial action, such as inhibition of protein kinases and host-pathogen interaction related targets. Chemical structures and associated data are hereby made public to encourage additional drug lead identification efforts and further research into this disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gamo, Francisco-Javier -- Sanz, Laura M -- Vidal, Jaume -- de Cozar, Cristina -- Alvarez, Emilio -- Lavandera, Jose-Luis -- Vanderwall, Dana E -- Green, Darren V S -- Kumar, Vinod -- Hasan, Samiul -- Brown, James R -- Peishoff, Catherine E -- Cardon, Lon R -- Garcia-Bustos, Jose F -- England -- Nature. 2010 May 20;465(7296):305-10. doi: 10.1038/nature09107.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Tres Cantos Medicines Development Campus, GlaxoSmithKline, Severo Ochoa 2, 28760 Tres Cantos, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20485427" target="_blank"〉PubMed〈/a〉

    Description: The canonical role of messenger RNA (mRNA) is to deliver protein-coding information to sites of protein synthesis. However, given that microRNAs bind to RNAs, we hypothesized that RNAs could possess a regulatory role that relies on their ability to compete for microRNA binding, independently of their protein-coding function. As a model for the protein-coding-independent role of RNAs, we describe the functional relationship between the mRNAs produced by the PTEN tumour suppressor gene and its pseudogene PTENP1 and the critical consequences of this interaction. We find that PTENP1 is biologically active as it can regulate cellular levels of PTEN and exert a growth-suppressive role. We also show that the PTENP1 locus is selectively lost in human cancer. We extended our analysis to other cancer-related genes that possess pseudogenes, such as oncogenic KRAS. We also demonstrate that the transcripts of protein-coding genes such as PTEN are biologically active. These findings attribute a novel biological role to expressed pseudogenes, as they can regulate coding gene expression, and reveal a non-coding function for mRNAs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3206313/" 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/PMC3206313/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Poliseno, Laura -- Salmena, Leonardo -- Zhang, Jiangwen -- Carver, Brett -- Haveman, William J -- Pandolfi, Pier Paolo -- R01 CA-82328-09/CA/NCI NIH HHS/ -- R01 CA102142/CA/NCI NIH HHS/ -- R01 CA102142-07/CA/NCI NIH HHS/ -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2010 Jun 24;465(7301):1033-8. doi: 10.1038/nature09144.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Genetics Program, Beth Israel Deaconess Cancer Center, Department of Medicine, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts 02215, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20577206" target="_blank"〉PubMed〈/a〉

    Description: Influenza A virus, being responsible for seasonal epidemics and reoccurring pandemics, represents a worldwide threat to public health. High mutation rates facilitate the generation of viral escape mutants, rendering vaccines and drugs directed against virus-encoded targets potentially ineffective. In contrast, targeting host cell determinants temporarily dispensable for the host but crucial for virus replication could prevent viral escape. Here we report the discovery of 287 human host cell genes influencing influenza A virus replication in a genome-wide RNA interference (RNAi) screen. Using an independent assay we confirmed 168 hits (59%) inhibiting either the endemic H1N1 (119 hits) or the current pandemic swine-origin (121 hits) influenza A virus strains, with an overlap of 60%. Notably, a subset of these common hits was also essential for replication of a highly pathogenic avian H5N1 strain. In-depth analyses of several factors provided insights into their infection stage relevance. Notably, SON DNA binding protein (SON) was found to be important for normal trafficking of influenza virions to late endosomes early in infection. We also show that a small molecule inhibitor of CDC-like kinase 1 (CLK1) reduces influenza virus replication by more than two orders of magnitude, an effect connected with impaired splicing of the viral M2 messenger RNA. Furthermore, influenza-virus-infected p27(-/-) (cyclin-dependent kinase inhibitor 1B; Cdkn1b) mice accumulated significantly lower viral titres in the lung, providing in vivo evidence for the importance of this gene. Thus, our results highlight the potency of genome-wide RNAi screening for the dissection of virus-host interactions and the identification of drug targets for a broad range of influenza viruses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karlas, Alexander -- Machuy, Nikolaus -- Shin, Yujin -- Pleissner, Klaus-Peter -- Artarini, Anita -- Heuer, Dagmar -- Becker, Daniel -- Khalil, Hany -- Ogilvie, Lesley A -- Hess, Simone -- Maurer, Andre P -- Muller, Elke -- Wolff, Thorsten -- Rudel, Thomas -- Meyer, Thomas F -- England -- Nature. 2010 Feb 11;463(7282):818-22. doi: 10.1038/nature08760.

    Description: Plasmodium falciparum is the most prevalent and lethal of the malaria parasites infecting humans, yet the origin and evolutionary history of this important pathogen remain controversial. Here we develop a single-genome amplification strategy to identify and characterize Plasmodium spp. DNA sequences in faecal samples from wild-living apes. Among nearly 3,000 specimens collected from field sites throughout central Africa, we found Plasmodium infection in chimpanzees (Pan troglodytes) and western gorillas (Gorilla gorilla), but not in eastern gorillas (Gorilla beringei) or bonobos (Pan paniscus). Ape plasmodial infections were highly prevalent, widely distributed and almost always made up of mixed parasite species. Analysis of more than 1,100 mitochondrial, apicoplast and nuclear gene sequences from chimpanzees and gorillas revealed that 99% grouped within one of six host-specific lineages representing distinct Plasmodium species within the subgenus Laverania. One of these from western gorillas comprised parasites that were nearly identical to P. falciparum. In phylogenetic analyses of full-length mitochondrial sequences, human P. falciparum formed a monophyletic lineage within the gorilla parasite radiation. These findings indicate that P. falciparum is of gorilla origin and not of chimpanzee, bonobo or ancient human origin.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2997044/" 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/PMC2997044/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Weimin -- Li, Yingying -- Learn, Gerald H -- Rudicell, Rebecca S -- Robertson, Joel D -- Keele, Brandon F -- Ndjango, Jean-Bosco N -- Sanz, Crickette M -- Morgan, David B -- Locatelli, Sabrina -- Gonder, Mary K -- Kranzusch, Philip J -- Walsh, Peter D -- Delaporte, Eric -- Mpoudi-Ngole, Eitel -- Georgiev, Alexander V -- Muller, Martin N -- Shaw, George M -- Peeters, Martine -- Sharp, Paul M -- Rayner, Julian C -- Hahn, Beatrice H -- P30 AI 7767/AI/NIAID NIH HHS/ -- P30 AI027767/AI/NIAID NIH HHS/ -- P30 AI027767-21A1/AI/NIAID NIH HHS/ -- R01 AI058715/AI/NIAID NIH HHS/ -- R01 AI058715-06A1/AI/NIAID NIH HHS/ -- R01 AI058715-07/AI/NIAID NIH HHS/ -- R01 AI50529/AI/NIAID NIH HHS/ -- R01 I58715/PHS HHS/ -- R03 AI074778/AI/NIAID NIH HHS/ -- R03 AI074778-02/AI/NIAID NIH HHS/ -- R37 AI050529/AI/NIAID NIH HHS/ -- R37 AI050529-07/AI/NIAID NIH HHS/ -- R37 AI050529-08/AI/NIAID NIH HHS/ -- T32 AI007245/AI/NIAID NIH HHS/ -- T32 AI007245-26/AI/NIAID NIH HHS/ -- T32 GM008111/GM/NIGMS NIH HHS/ -- T32 GM008111-13/GM/NIGMS NIH HHS/ -- U19 AI 067854/AI/NIAID NIH HHS/ -- U19 AI067854/AI/NIAID NIH HHS/ -- U19 AI067854-06/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- Wellcome Trust/United Kingdom -- England -- Nature. 2010 Sep 23;467(7314):420-5. doi: 10.1038/nature09442.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of Alabama at Birmingham, Birmingham, Alabama 35294, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20864995" target="_blank"〉PubMed〈/a〉

    Description: Ca(2+) channels and calmodulin (CaM) are two prominent signalling hubs that synergistically affect functions as diverse as cardiac excitability, synaptic plasticity and gene transcription. It is therefore fitting that these hubs are in some sense coordinated, as the opening of Ca(V)1-2 Ca(2+) channels are regulated by a single CaM constitutively complexed with channels. The Ca(2+)-free form of CaM (apoCaM) is already pre-associated with the isoleucine-glutamine (IQ) domain on the channel carboxy terminus, and subsequent Ca(2+) binding to this 'resident' CaM drives conformational changes that then trigger regulation of channel opening. Another potential avenue for channel-CaM coordination could arise from the absence of Ca(2+) regulation in channels lacking a pre-associated CaM. Natural fluctuations in CaM concentrations might then influence the fraction of regulable channels and, thereby, the overall strength of Ca(2+) feedback. However, the prevailing view has been that the ultrastrong affinity of channels for apoCaM ensures their saturation with CaM, yielding a significant form of concentration independence between Ca(2+) channels and CaM. Here we show that significant exceptions to this autonomy exist, by combining electrophysiology (to characterize channel regulation) with optical fluorescence resonance energy transfer (FRET) sensor determination of free-apoCaM concentration in live cells. This approach translates quantitative CaM biochemistry from the traditional test-tube context into the realm of functioning holochannels within intact cells. From this perspective, we find that long splice forms of Ca(V)1.3 and Ca(V)1.4 channels include a distal carboxy tail that resembles an enzyme competitive inhibitor that retunes channel affinity for apoCaM such that natural CaM variations affect the strength of Ca(2+) feedback modulation. Given the ubiquity of these channels, the connection between ambient CaM levels and Ca(2+) entry through channels is broadly significant for Ca(2+) homeostasis. Strategies such as ours promise key advances for the in situ analysis of signalling molecules resistant to in vitro reconstitution, such as Ca(2+) channels.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3553577/" 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/PMC3553577/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Xiaodong -- Yang, Philemon S -- Yang, Wanjun -- Yue, David T -- P30 DC005211/DC/NIDCD NIH HHS/ -- R01 DC000276/DC/NIDCD NIH HHS/ -- England -- Nature. 2010 Feb 18;463(7283):968-72. doi: 10.1038/nature08766.

    Description: Oncogenic mutations in the serine/threonine kinase B-RAF (also known as BRAF) are found in 50-70% of malignant melanomas. Pre-clinical studies have demonstrated that the B-RAF(V600E) mutation predicts a dependency on the mitogen-activated protein kinase (MAPK) signalling cascade in melanoma-an observation that has been validated by the success of RAF and MEK inhibitors in clinical trials. However, clinical responses to targeted anticancer therapeutics are frequently confounded by de novo or acquired resistance. Identification of resistance mechanisms in a manner that elucidates alternative 'druggable' targets may inform effective long-term treatment strategies. Here we expressed approximately 600 kinase and kinase-related open reading frames (ORFs) in parallel to interrogate resistance to a selective RAF kinase inhibitor. We identified MAP3K8 (the gene encoding COT/Tpl2) as a MAPK pathway agonist that drives resistance to RAF inhibition in B-RAF(V600E) cell lines. COT activates ERK primarily through MEK-dependent mechanisms that do not require RAF signalling. Moreover, COT expression is associated with de novo resistance in B-RAF(V600E) cultured cell lines and acquired resistance in melanoma cells and tissue obtained from relapsing patients following treatment with MEK or RAF inhibitors. We further identify combinatorial MAPK pathway inhibition or targeting of COT kinase activity as possible therapeutic strategies for reducing MAPK pathway activation in this setting. Together, these results provide new insights into resistance mechanisms involving the MAPK pathway and articulate an integrative approach through which high-throughput functional screens may inform the development of novel therapeutic strategies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3058384/" 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/PMC3058384/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johannessen, Cory M -- Boehm, Jesse S -- Kim, So Young -- Thomas, Sapana R -- Wardwell, Leslie -- Johnson, Laura A -- Emery, Caroline M -- Stransky, Nicolas -- Cogdill, Alexandria P -- Barretina, Jordi -- Caponigro, Giordano -- Hieronymus, Haley -- Murray, Ryan R -- Salehi-Ashtiani, Kourosh -- Hill, David E -- Vidal, Marc -- Zhao, Jean J -- Yang, Xiaoping -- Alkan, Ozan -- Kim, Sungjoon -- Harris, Jennifer L -- Wilson, Christopher J -- Myer, Vic E -- Finan, Peter M -- Root, David E -- Roberts, Thomas M -- Golub, Todd -- Flaherty, Keith T -- Dummer, Reinhard -- Weber, Barbara L -- Sellers, William R -- Schlegel, Robert -- Wargo, Jennifer A -- Hahn, William C -- Garraway, Levi A -- CA134502/CA/NCI NIH HHS/ -- DP2 OD002750/OD/NIH HHS/ -- DP2 OD002750-01/OD/NIH HHS/ -- K08 CA115927/CA/NCI NIH HHS/ -- K08 CA115927-05/CA/NCI NIH HHS/ -- P50 CA093683/CA/NCI NIH HHS/ -- R01 CA134502/CA/NCI NIH HHS/ -- R33 CA128625/CA/NCI NIH HHS/ -- RC2 CA148268/CA/NCI NIH HHS/ -- England -- Nature. 2010 Dec 16;468(7326):968-72. doi: 10.1038/nature09627.

    Description: The worldwide prevalence of chronic hepatitis C virus (HCV) infection is estimated to be approaching 200 million people. Current therapy relies upon a combination of pegylated interferon-alpha and ribavirin, a poorly tolerated regimen typically associated with less than 50% sustained virological response rate in those infected with genotype 1 virus. The development of direct-acting antiviral agents to treat HCV has focused predominantly on inhibitors of the viral enzymes NS3 protease and the RNA-dependent RNA polymerase NS5B. Here we describe the profile of BMS-790052, a small molecule inhibitor of the HCV NS5A protein that exhibits picomolar half-maximum effective concentrations (EC(50)) towards replicons expressing a broad range of HCV genotypes and the JFH-1 genotype 2a infectious virus in cell culture. In a phase I clinical trial in patients chronically infected with HCV, administration of a single 100-mg dose of BMS-790052 was associated with a 3.3 log(10) reduction in mean viral load measured 24 h post-dose that was sustained for an additional 120 h in two patients infected with genotype 1b virus. Genotypic analysis of samples taken at baseline, 24 and 144 h post-dose revealed that the major HCV variants observed had substitutions at amino-acid positions identified using the in vitro replicon system. These results provide the first clinical validation of an inhibitor of HCV NS5A, a protein with no known enzymatic function, as an approach to the suppression of virus replication that offers potential as part of a therapeutic regimen based on combinations of HCV inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gao, Min -- Nettles, Richard E -- Belema, Makonen -- Snyder, Lawrence B -- Nguyen, Van N -- Fridell, Robert A -- Serrano-Wu, Michael H -- Langley, David R -- Sun, Jin-Hua -- O'Boyle, Donald R 2nd -- Lemm, Julie A -- Wang, Chunfu -- Knipe, Jay O -- Chien, Caly -- Colonno, Richard J -- Grasela, Dennis M -- Meanwell, Nicholas A -- Hamann, Lawrence G -- England -- Nature. 2010 May 6;465(7294):96-100. doi: 10.1038/nature08960.

    Description: Tumours with mutant BRAF are dependent on the RAF-MEK-ERK signalling pathway for their growth. We found that ATP-competitive RAF inhibitors inhibit ERK signalling in cells with mutant BRAF, but unexpectedly enhance signalling in cells with wild-type BRAF. Here we demonstrate the mechanistic basis for these findings. We used chemical genetic methods to show that drug-mediated transactivation of RAF dimers is responsible for paradoxical activation of the enzyme by inhibitors. Induction of ERK signalling requires direct binding of the drug to the ATP-binding site of one kinase of the dimer and is dependent on RAS activity. Drug binding to one member of RAF homodimers (CRAF-CRAF) or heterodimers (CRAF-BRAF) inhibits one protomer, but results in transactivation of the drug-free protomer. In BRAF(V600E) tumours, RAS is not activated, thus transactivation is minimal and ERK signalling is inhibited in cells exposed to RAF inhibitors. These results indicate that RAF inhibitors will be effective in tumours in which BRAF is mutated. Furthermore, because RAF inhibitors do not inhibit ERK signalling in other cells, the model predicts that they would have a higher therapeutic index and greater antitumour activity than mitogen-activated protein kinase (MEK) inhibitors, but could also cause toxicity due to MEK/ERK activation. These predictions have been borne out in a recent clinical trial of the RAF inhibitor PLX4032 (refs 4, 5). The model indicates that promotion of RAF dimerization by elevation of wild-type RAF expression or RAS activity could lead to drug resistance in mutant BRAF tumours. In agreement with this prediction, RAF inhibitors do not inhibit ERK signalling in cells that coexpress BRAF(V600E) and mutant RAS.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3178447/" 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/PMC3178447/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Poulikakos, Poulikos I -- Zhang, Chao -- Bollag, Gideon -- Shokat, Kevan M -- Rosen, Neal -- 1P01CA129243-02/CA/NCI NIH HHS/ -- 2R01EB001987/EB/NIBIB NIH HHS/ -- P01 CA129243-010002/CA/NCI NIH HHS/ -- R01 EB001987/EB/NIBIB NIH HHS/ -- U01 CA091178/CA/NCI NIH HHS/ -- U01 CA091178-01/CA/NCI NIH HHS/ -- England -- Nature. 2010 Mar 18;464(7287):427-30. doi: 10.1038/nature08902.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Molecular Pharmacology and Chemistry and Department of Medicine, Memorial Sloan-Kettering Cancer Center, New York, New York 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20179705" target="_blank"〉PubMed〈/a〉

    Description: Developing a human immunodeficiency virus (HIV) vaccine is critical to end the global acquired immunodeficiency syndrome (AIDS) epidemic, but many question whether this goal is achievable. Natural immunity is not protective, and despite immunogenicity of HIV vaccine candidates, human trials have exclusively yielded disappointing results. Nevertheless, there is an indication that success may be possible, but this will be dependent on understanding the antiviral immune response in unprecedented depth to identify and engineer the types of immunity required. Here we outline fundamental immunological questions that need to be answered to develop a protective HIV vaccine, and the immediate need to harness a much broader scientific community to achieve this goal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Virgin, Herbert W -- Walker, Bruce D -- England -- Nature. 2010 Mar 11;464(7286):224-31. doi: 10.1038/nature08898.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Washington University School of Medicine and Midwest Regional Center of Excellence for Biodefense and Emerging Infectious Disease Research, Campus Box 8118, 660 South Euclid Avenue, Saint Louis, Missouri 63110, USA. virgin@wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20220841" target="_blank"〉PubMed〈/a〉

    Description: Endocytosis is a complex process fulfilling many cellular and developmental functions. Understanding how it is regulated and integrated with other cellular processes requires a comprehensive analysis of its molecular constituents and general design principles. Here, we developed a new strategy to phenotypically profile the human genome with respect to transferrin (TF) and epidermal growth factor (EGF) endocytosis by combining RNA interference, automated high-resolution confocal microscopy, quantitative multiparametric image analysis and high-performance computing. We identified several novel components of endocytic trafficking, including genes implicated in human diseases. We found that signalling pathways such as Wnt, integrin/cell adhesion, transforming growth factor (TGF)-beta and Notch regulate the endocytic system, and identified new genes involved in cargo sorting to a subset of signalling endosomes. A systems analysis by Bayesian networks further showed that the number, size, concentration of cargo and intracellular position of endosomes are not determined randomly but are subject to specific regulation, thus uncovering novel properties of the endocytic system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Collinet, Claudio -- Stoter, Martin -- Bradshaw, Charles R -- Samusik, Nikolay -- Rink, Jochen C -- Kenski, Denise -- Habermann, Bianca -- Buchholz, Frank -- Henschel, Robert -- Mueller, Matthias S -- Nagel, Wolfgang E -- Fava, Eugenio -- Kalaidzidis, Yannis -- Zerial, Marino -- England -- Nature. 2010 Mar 11;464(7286):243-9. doi: 10.1038/nature08779.

    Description: During early mammalian development, as the pluripotent cells that give rise to all of the tissues of the body proliferate and expand in number, they pass through transition states marked by a stepwise restriction in developmental potential and by changes in the expression of key regulatory genes. Recent findings show that cultured stem-cell lines derived from different stages of mouse development can mimic these transition states. They further reveal that there is a high degree of heterogeneity and plasticity in pluripotent populations in vitro and that these properties are modulated by extrinsic signalling. Understanding the extrinsic control of plasticity will guide efforts to use human pluripotent stem cells in research and therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pera, Martin F -- Tam, Patrick P L -- England -- Nature. 2010 Jun 10;465(7299):713-20. doi: 10.1038/nature09228.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Regenerative Medicine and Stem Cell Research, Keck School of Medicine, University of Southern California, Los Angeles, California 90033, USA. pera@usc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20535200" target="_blank"〉PubMed〈/a〉

    Description: Long interspersed element-1 (LINE-1 or L1) retrotransposition continues to affect human genome evolution. L1s can retrotranspose in the germline, during early development and in select somatic cells; however, the host response to L1 retrotransposition remains largely unexplored. Here we show that reporter genes introduced into the genome of various human embryonic carcinoma-derived cell lines (ECs) by L1 retrotransposition are rapidly and efficiently silenced either during or immediately after their integration. Treating ECs with histone deacetylase inhibitors rapidly reverses this silencing, and chromatin immunoprecipitation experiments revealed that reactivation of the reporter gene was correlated with changes in chromatin status at the L1 integration site. Under our assay conditions, rapid silencing was also observed when reporter genes were delivered into ECs by mouse L1s and a zebrafish LINE-2 element, but not when similar reporter genes were delivered into ECs by Moloney murine leukaemia virus or human immunodeficiency virus, suggesting that these integration events are silenced by distinct mechanisms. Finally, we demonstrate that subjecting ECs to culture conditions that promote differentiation attenuates the silencing of reporter genes delivered by L1 retrotransposition, but that differentiation, in itself, is not sufficient to reactivate previously silenced reporter genes. Thus, our data indicate that ECs differ from many differentiated cells in their ability to silence reporter genes delivered by L1 retrotransposition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3034402/" 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/PMC3034402/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garcia-Perez, Jose L -- Morell, Maria -- Scheys, Joshua O -- Kulpa, Deanna A -- Morell, Santiago -- Carter, Christoph C -- Hammer, Gary D -- Collins, Kathleen L -- O'Shea, K Sue -- Menendez, Pablo -- Moran, John V -- 5 P30 CA46592/CA/NCI NIH HHS/ -- GM-069985/GM/NIGMS NIH HHS/ -- GM060518/GM/NIGMS NIH HHS/ -- GM082970/GM/NIGMS NIH HHS/ -- NS-048187/NS/NINDS NIH HHS/ -- R01 DK62027/DK/NIDDK NIH HHS/ -- R01 GM060518/GM/NIGMS NIH HHS/ -- R01 GM060518-12/GM/NIGMS NIH HHS/ -- R01 GM082970/GM/NIGMS NIH HHS/ -- R01 GM082970-04/GM/NIGMS NIH HHS/ -- R01AI051198/AI/NIAID NIH HHS/ -- T32-GM08322/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Aug 5;466(7307):769-73. doi: 10.1038/nature09209.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Human Genetics, 1241 East Catherine Street, University of Michigan Medical School, Ann Arbor, Michigan 48109-5618, USA. josel.garcia.perez@juntadeandalucia.es〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20686575" target="_blank"〉PubMed〈/a〉

    Description: DNA polymerase eta (Poleta) is unique among eukaryotic polymerases in its proficient ability for error-free replication through ultraviolet-induced cyclobutane pyrimidine dimers, and inactivation of Poleta (also known as POLH) in humans causes the variant form of xeroderma pigmentosum (XPV). We present the crystal structures of Saccharomyces cerevisiae Poleta (also known as RAD30) in ternary complex with a cis-syn thymine-thymine (T-T) dimer and with undamaged DNA. The structures reveal that the ability of Poleta to replicate efficiently through the ultraviolet-induced lesion derives from a simple and yet elegant mechanism, wherein the two Ts of the T-T dimer are accommodated in an active site cleft that is much more open than in other polymerases. We also show by structural, biochemical and genetic analysis that the two Ts are maintained in a stable configuration in the active site via interactions with Gln 55, Arg 73 and Met 74. Together, these features define the basis for Poleta's action on ultraviolet-damaged DNA that is crucial in suppressing the mutagenic and carcinogenic consequences of sun exposure, thereby reducing the incidence of skin cancers in humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3030469/" 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/PMC3030469/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Silverstein, Timothy D -- Johnson, Robert E -- Jain, Rinku -- Prakash, Louise -- Prakash, Satya -- Aggarwal, Aneel K -- P30 EB009998/EB/NIBIB NIH HHS/ -- R01 CA107650/CA/NCI NIH HHS/ -- R01 CA107650-39/CA/NCI NIH HHS/ -- R01 ES017767/ES/NIEHS NIH HHS/ -- R01 ES017767-01/ES/NIEHS NIH HHS/ -- England -- Nature. 2010 Jun 24;465(7301):1039-43. doi: 10.1038/nature09104.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Structural and Chemical Biology, Mount Sinai School of Medicine, Box 1677, 1425 Madison Avenue, New York, New York 10029, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20577207" target="_blank"〉PubMed〈/a〉

    Description: RANK ligand (RANKL), a TNF-related molecule, is essential for osteoclast formation, function and survival through interaction with its receptor RANK. Mammary glands of RANK- and RANKL-deficient mice develop normally during sexual maturation, but fail to form lobuloalveolar structures during pregnancy because of defective proliferation and increased apoptosis of mammary epithelium. It has been shown that RANKL is responsible for the major proliferative response of mouse mammary epithelium to progesterone during mammary lactational morphogenesis, and in mouse models, manipulated to induce activation of the RANK/RANKL pathway in the absence of strict hormonal control, inappropriate mammary proliferation is observed. However, there is no evidence so far of a functional contribution of RANKL to tumorigenesis. Here we show that RANK and RANKL are expressed within normal, pre-malignant and neoplastic mammary epithelium, and using complementary gain-of-function (mouse mammary tumour virus (MMTV)-RANK transgenic mice) and loss-of function (pharmacological inhibition of RANKL) approaches, define a direct contribution of this pathway in mammary tumorigenesis. Accelerated pre-neoplasias and increased mammary tumour formation were observed in MMTV-RANK transgenic mice after multiparity or treatment with carcinogen and hormone (progesterone). Reciprocally, selective pharmacological inhibition of RANKL attenuated mammary tumour development not only in hormone- and carcinogen-treated MMTV-RANK and wild-type mice, but also in the MMTV-neu transgenic spontaneous tumour model. The reduction in tumorigenesis upon RANKL inhibition was preceded by a reduction in pre-neoplasias as well as rapid and sustained reductions in hormone- and carcinogen-induced mammary epithelial proliferation and cyclin D1 levels. Collectively, our results indicate that RANKL inhibition is acting directly on hormone-induced mammary epithelium at early stages in tumorigenesis, and the permissive contribution of progesterone to increased mammary cancer incidence is due to RANKL-dependent proliferative changes in the mammary epithelium. The current study highlights a potential role for RANKL inhibition in the management of proliferative breast disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gonzalez-Suarez, Eva -- Jacob, Allison P -- Jones, Jon -- Miller, Robert -- Roudier-Meyer, Martine P -- Erwert, Ryan -- Pinkas, Jan -- Branstetter, Dan -- Dougall, William C -- England -- Nature. 2010 Nov 4;468(7320):103-7. doi: 10.1038/nature09495.

    Description: Impulsivity, describing action without foresight, is an important feature of several psychiatric diseases, suicidality and violent behaviour. The complex origins of impulsivity hinder identification of the genes influencing it and the diseases with which it is associated. Here we perform exon-focused sequencing of impulsive individuals in a founder population, targeting fourteen genes belonging to the serotonin and dopamine domain. A stop codon in HTR2B was identified that is common (minor allele frequency 〉 1%) but exclusive to Finnish people. Expression of the gene in the human brain was assessed, as well as the molecular functionality of the stop codon, which was associated with psychiatric diseases marked by impulsivity in both population and family-based analyses. Knockout of Htr2b increased impulsive behaviours in mice, indicative of predictive validity. Our study shows the potential for identifying and tracing effects of rare alleles in complex behavioural phenotypes using founder populations, and indicates a role for HTR2B in impulsivity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3183507/" 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/PMC3183507/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bevilacqua, Laura -- Doly, Stephane -- Kaprio, Jaakko -- Yuan, Qiaoping -- Tikkanen, Roope -- Paunio, Tiina -- Zhou, Zhifeng -- Wedenoja, Juho -- Maroteaux, Luc -- Diaz, Silvina -- Belmer, Arnaud -- Hodgkinson, Colin A -- Dell'osso, Liliana -- Suvisaari, Jaana -- Coccaro, Emil -- Rose, Richard J -- Peltonen, Leena -- Virkkunen, Matti -- Goldman, David -- AA-09203/AA/NIAAA NIH HHS/ -- AA-12502/AA/NIAAA NIH HHS/ -- Z01 AA000301-09/Intramural NIH HHS/ -- Z01 AA000301-10/Intramural NIH HHS/ -- Z99 AA999999/Intramural NIH HHS/ -- England -- Nature. 2010 Dec 23;468(7327):1061-6. doi: 10.1038/nature09629.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Neurogenetics, National Institute on Alcohol Abuse and Alcoholism, NIH, Rockville, Maryland 20852, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21179162" target="_blank"〉PubMed〈/a〉

    Description: Mitochondrial calcium uptake has a central role in cell physiology by stimulating ATP production, shaping cytosolic calcium transients and regulating cell death. The biophysical properties of mitochondrial calcium uptake have been studied in detail, but the underlying proteins remain elusive. Here we use an integrative strategy to predict human genes involved in mitochondrial calcium entry based on clues from comparative physiology, evolutionary genomics and organelle proteomics. RNA interference against 13 top candidates highlighted one gene, CBARA1, that we call hereafter mitochondrial calcium uptake 1 (MICU1). Silencing MICU1 does not disrupt mitochondrial respiration or membrane potential but abolishes mitochondrial calcium entry in intact and permeabilized cells, and attenuates the metabolic coupling between cytosolic calcium transients and activation of matrix dehydrogenases. MICU1 is associated with the mitochondrial inner membrane and has two canonical EF hands that are essential for its activity, indicating a role in calcium sensing. MICU1 represents the founding member of a set of proteins required for high-capacity mitochondrial calcium uptake. Its discovery may lead to the complete molecular characterization of mitochondrial calcium uptake pathways, and offers genetic strategies for understanding their contribution to normal physiology and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2977980/" 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/PMC2977980/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perocchi, Fabiana -- Gohil, Vishal M -- Girgis, Hany S -- Bao, X Robert -- McCombs, Janet E -- Palmer, Amy E -- Mootha, Vamsi K -- DK080261/DK/NIDDK NIH HHS/ -- GM0077465/GM/NIGMS NIH HHS/ -- GM084027/GM/NIGMS NIH HHS/ -- R01 GM077465/GM/NIGMS NIH HHS/ -- R01 GM077465-01A1/GM/NIGMS NIH HHS/ -- R01 GM077465-02/GM/NIGMS NIH HHS/ -- R01 GM077465-03/GM/NIGMS NIH HHS/ -- R01 GM077465-04/GM/NIGMS NIH HHS/ -- R01 GM077465-05/GM/NIGMS NIH HHS/ -- R01 GM077465-06/GM/NIGMS NIH HHS/ -- R01 GM084027/GM/NIGMS NIH HHS/ -- R24 DK080261/DK/NIDDK NIH HHS/ -- R24 DK080261-04/DK/NIDDK NIH HHS/ -- TR2 GM08759/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Sep 16;467(7313):291-6. doi: 10.1038/nature09358.

    Description: Reciprocity of inflammation, oxidative stress and neovascularization is emerging as an important mechanism underlying numerous processes from tissue healing and remodelling to cancer progression. Whereas the mechanism of hypoxia-driven angiogenesis is well understood, the link between inflammation-induced oxidation and de novo blood vessel growth remains obscure. Here we show that the end products of lipid oxidation, omega-(2-carboxyethyl)pyrrole (CEP) and other related pyrroles, are generated during inflammation and wound healing and accumulate at high levels in ageing tissues in mice and in highly vascularized tumours in both murine and human melanoma. The molecular patterns of carboxyalkylpyrroles are recognized by Toll-like receptor 2 (TLR2), but not TLR4 or scavenger receptors on endothelial cells, leading to an angiogenic response that is independent of vascular endothelial growth factor. CEP promoted angiogenesis in hindlimb ischaemia and wound healing models through MyD88-dependent TLR2 signalling. Neutralization of endogenous carboxyalkylpyrroles impaired wound healing and tissue revascularization and diminished tumour angiogenesis. Both TLR2 and MyD88 are required for CEP-induced stimulation of Rac1 and endothelial migration. Taken together, these findings establish a new function of TLR2 as a sensor of oxidation-associated molecular patterns, providing a key link connecting inflammation, oxidative stress, innate immunity and angiogenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2990914/" 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/PMC2990914/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉West, Xiaoxia Z -- Malinin, Nikolay L -- Merkulova, Alona A -- Tischenko, Mira -- Kerr, Bethany A -- Borden, Ernest C -- Podrez, Eugene A -- Salomon, Robert G -- Byzova, Tatiana V -- CA126847/CA/NCI NIH HHS/ -- GM021249/GM/NIGMS NIH HHS/ -- HL071625/HL/NHLBI NIH HHS/ -- HL073311/HL/NHLBI NIH HHS/ -- HL077213/HL/NHLBI NIH HHS/ -- R01 HL071625/HL/NHLBI NIH HHS/ -- R01 HL071625-07/HL/NHLBI NIH HHS/ -- R01 HL071625-08/HL/NHLBI NIH HHS/ -- R01 HL077213/HL/NHLBI NIH HHS/ -- England -- Nature. 2010 Oct 21;467(7318):972-6. doi: 10.1038/nature09421.

    Description: Primary cilia are evolutionarily conserved cellular organelles that organize diverse signalling pathways. Defects in the formation or function of primary cilia are associated with a spectrum of human diseases and developmental abnormalities. Genetic screens in model organisms have discovered core machineries of cilium assembly and maintenance. However, regulatory molecules that coordinate the biogenesis of primary cilia with other cellular processes, including cytoskeletal organization, vesicle trafficking and cell-cell adhesion, remain to be identified. Here we report the results of a functional genomic screen using RNA interference (RNAi) to identify human genes involved in ciliogenesis control. The screen identified 36 positive and 13 negative ciliogenesis modulators, which include molecules involved in actin dynamics and vesicle trafficking. Further investigation demonstrated that blocking actin assembly facilitates ciliogenesis by stabilizing the pericentrosomal preciliary compartment (PPC), a previously uncharacterized compact vesiculotubular structure storing transmembrane proteins destined for cilia during the early phase of ciliogenesis. The PPC was labelled by recycling endosome markers. Moreover, knockdown of modulators that are involved in the endocytic recycling pathway affected the formation of the PPC as well as ciliogenesis. Our results uncover a critical regulatory step that couples actin dynamics and endocytic recycling with ciliogenesis, and also provides potential target molecules for future study.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2929961/" 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/PMC2929961/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Joon -- Lee, Ji Eun -- Heynen-Genel, Susanne -- Suyama, Eigo -- Ono, Keiichiro -- Lee, Kiyoung -- Ideker, Trey -- Aza-Blanc, Pedro -- Gleeson, Joseph G -- GM070743/GM/NIGMS NIH HHS/ -- P30 CA023100/CA/NCI NIH HHS/ -- P30 CA23100/CA/NCI NIH HHS/ -- P30 NS047101/NS/NINDS NIH HHS/ -- P30 NS057096/NS/NINDS NIH HHS/ -- R01 GM070743/GM/NIGMS NIH HHS/ -- R01 NS052455/NS/NINDS NIH HHS/ -- R01 NS052455-05/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Apr 15;464(7291):1048-51. doi: 10.1038/nature08895.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurosciences, Institute for Genomic Medicine, Howard Hughes Medical Institute, University of California San Diego, La Jolla, California 92093, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20393563" target="_blank"〉PubMed〈/a〉

    Description: Eusociality, in which some individuals reduce their own lifetime reproductive potential to raise the offspring of others, underlies the most advanced forms of social organization and the ecologically dominant role of social insects and humans. For the past four decades kin selection theory, based on the concept of inclusive fitness, has been the major theoretical attempt to explain the evolution of eusociality. Here we show the limitations of this approach. We argue that standard natural selection theory in the context of precise models of population structure represents a simpler and superior approach, allows the evaluation of multiple competing hypotheses, and provides an exact framework for interpreting empirical observations.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3279739/" 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/PMC3279739/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nowak, Martin A -- Tarnita, Corina E -- Wilson, Edward O -- R01 GM078986/GM/NIGMS NIH HHS/ -- R01 GM078986-04/GM/NIGMS NIH HHS/ -- R01GM078986/GM/NIGMS NIH HHS/ -- England -- Nature. 2010 Aug 26;466(7310):1057-62. doi: 10.1038/nature09205.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program for Evolutionary Dynamics, Department of Mathematics, Harvard University, Cambridge, Massachusetts 02138, USA. martin_nowak@harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20740005" target="_blank"〉PubMed〈/a〉

    Description: Vitamin K epoxide reductase (VKOR) generates vitamin K hydroquinone to sustain gamma-carboxylation of many blood coagulation factors. Here, we report the 3.6 A crystal structure of a bacterial homologue of VKOR from Synechococcus sp. The structure shows VKOR in complex with its naturally fused redox partner, a thioredoxin-like domain, and corresponds to an arrested state of electron transfer. The catalytic core of VKOR is a four transmembrane helix bundle that surrounds a quinone, connected through an additional transmembrane segment with the periplasmic thioredoxin-like domain. We propose a pathway for how VKOR uses electrons from cysteines of newly synthesized proteins to reduce a quinone, a mechanism confirmed by in vitro reconstitution of vitamin K-dependent disulphide bridge formation. Our results have implications for the mechanism of the mammalian VKOR and explain how mutations can cause resistance to the VKOR inhibitor warfarin, the most commonly used oral anticoagulant.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2919313/" 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/PMC2919313/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Weikai -- Schulman, Sol -- Dutton, Rachel J -- Boyd, Dana -- Beckwith, Jon -- Rapoport, Tom A -- GMO41883/PHS HHS/ -- K99 HL097083/HL/NHLBI NIH HHS/ -- K99 HL097083-01/HL/NHLBI NIH HHS/ -- K991K99HL097083/HL/NHLBI NIH HHS/ -- R00 HL097083/HL/NHLBI NIH HHS/ -- R01 GM041883/GM/NIGMS NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Jan 28;463(7280):507-12. doi: 10.1038/nature08720.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Cell Biology, Harvard Medical School, 240 Longwood Avenue, Boston, Massachusetts 02115, USA. weikai@crystal.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20110994" target="_blank"〉PubMed〈/a〉

    Description: Blood pressure is critically controlled by angiotensins, which are vasopressor peptides specifically released by the enzyme renin from the tail of angiotensinogen-a non-inhibitory member of the serpin family of protease inhibitors. Although angiotensinogen has long been regarded as a passive substrate, the crystal structures solved here to 2.1 A resolution show that the angiotensin cleavage site is inaccessibly buried in its amino-terminal tail. The conformational rearrangement that makes this site accessible for proteolysis is revealed in our 4.4 A structure of the complex of human angiotensinogen with renin. The co-ordinated changes involved are seen to be critically linked by a conserved but labile disulphide bridge. Here we show that the reduced unbridged form of angiotensinogen is present in the circulation in a near 40:60 ratio with the oxidized sulphydryl-bridged form, which preferentially interacts with receptor-bound renin. We propose that this redox-responsive transition of angiotensinogen to a form that will more effectively release angiotensin at a cellular level contributes to the modulation of blood pressure. Specifically, we demonstrate the oxidative switch of angiotensinogen to its more active sulphydryl-bridged form in the maternal circulation in pre-eclampsia-the hypertensive crisis of pregnancy that threatens the health and survival of both mother and child.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3024006/" 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/PMC3024006/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, Aiwu -- Carrell, Robin W -- Murphy, Michael P -- Wei, Zhenquan -- Yan, Yahui -- Stanley, Peter L D -- Stein, Penelope E -- Broughton Pipkin, Fiona -- Read, Randy J -- 082961/Wellcome Trust/United Kingdom -- BS/05/002/18361/British Heart Foundation/United Kingdom -- MC_U105663142/Medical Research Council/United Kingdom -- PG/08/041/24818/British Heart Foundation/United Kingdom -- PG/09/072/27945/British Heart Foundation/United Kingdom -- British Heart Foundation/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2010 Nov 4;468(7320):108-11. doi: 10.1038/nature09505.

    Description: Copper is an essential trace element for eukaryotes and most prokaryotes. However, intracellular free copper must be strictly limited because of its toxic side effects. Complex systems for copper trafficking evolved to satisfy cellular requirements while minimizing toxicity. The factors driving the copper transfer between protein partners along cellular copper routes are, however, not fully rationalized. Until now, inconsistent, scattered and incomparable data on the copper-binding affinities of copper proteins have been reported. Here we determine, through a unified electrospray ionization mass spectrometry (ESI-MS)-based strategy, in an environment that mimics the cellular redox milieu, the apparent Cu(I)-binding affinities for a representative set of intracellular copper proteins involved in enzymatic redox catalysis, in copper trafficking to and within various cellular compartments, and in copper storage. The resulting thermodynamic data show that copper is drawn to the enzymes that require it by passing from one copper protein site to another, exploiting gradients of increasing copper-binding affinity. This result complements the finding that fast copper-transfer pathways require metal-mediated protein-protein interactions and therefore protein-protein specific recognition. Together with Cu,Zn-SOD1, metallothioneins have the highest affinity for copper(I), and may play special roles in the regulation of cellular copper distribution; however, for kinetic reasons they cannot demetallate copper enzymes.

    Description: Cell-cell signalling of semaphorin ligands through interaction with plexin receptors is important for the homeostasis and morphogenesis of many tissues and is widely studied for its role in neural connectivity, cancer, cell migration and immune responses. SEMA4D and Sema6A exemplify two diverse vertebrate, membrane-spanning semaphorin classes (4 and 6) that are capable of direct signalling through members of the two largest plexin classes, B and A, respectively. In the absence of any structural information on the plexin ectodomain or its interaction with semaphorins the extracellular specificity and mechanism controlling plexin signalling has remained unresolved. Here we present crystal structures of cognate complexes of the semaphorin-binding regions of plexins B1 and A2 with semaphorin ectodomains (human PLXNB1(1-2)-SEMA4D(ecto) and murine PlxnA2(1-4)-Sema6A(ecto)), plus unliganded structures of PlxnA2(1-4) and Sema6A(ecto). These structures, together with biophysical and cellular assays of wild-type and mutant proteins, reveal that semaphorin dimers independently bind two plexin molecules and that signalling is critically dependent on the avidity of the resulting bivalent 2:2 complex (monomeric semaphorin binds plexin but fails to trigger signalling). In combination, our data favour a cell-cell signalling mechanism involving semaphorin-stabilized plexin dimerization, possibly followed by clustering, which is consistent with previous functional data. Furthermore, the shared generic architecture of the complexes, formed through conserved contacts of the amino-terminal seven-bladed beta-propeller (sema) domains of both semaphorin and plexin, suggests that a common mode of interaction triggers all semaphorin-plexin based signalling, while distinct insertions within or between blades of the sema domains determine binding specificity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3587840/" 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/PMC3587840/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Janssen, Bert J C -- Robinson, Ross A -- Perez-Branguli, Francesc -- Bell, Christian H -- Mitchell, Kevin J -- Siebold, Christian -- Jones, E Yvonne -- 082301/Wellcome Trust/United Kingdom -- 083111/Wellcome Trust/United Kingdom -- 10976/Cancer Research UK/United Kingdom -- A10976/Cancer Research UK/United Kingdom -- A3964/Cancer Research UK/United Kingdom -- A5261/Cancer Research UK/United Kingdom -- G0700232/Medical Research Council/United Kingdom -- G0700232(82098)/Medical Research Council/United Kingdom -- G0900084/Medical Research Council/United Kingdom -- G9900061/Medical Research Council/United Kingdom -- G9900061(69203)/Medical Research Council/United Kingdom -- Cancer Research UK/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2010 Oct 28;467(7319):1118-22. doi: 10.1038/nature09468.

    Description: CD95 (also called Fas and APO-1) is a prototypical death receptor that regulates tissue homeostasis mainly in the immune system through the induction of apoptosis. During cancer progression CD95 is frequently downregulated or cells are rendered apoptosis resistant, raising the possibility that loss of CD95 is part of a mechanism for tumour evasion. However, complete loss of CD95 is rarely seen in human cancers and many cancer cells express large quantities of CD95 and are highly sensitive to CD95-mediated apoptosis in vitro. Furthermore, cancer patients frequently have elevated levels of the physiological ligand for CD95, CD95L. These data raise the possibility that CD95 could actually promote the growth of tumours through its non-apoptotic activities. Here we show that cancer cells in general, regardless of their CD95 apoptosis sensitivity, depend on constitutive activity of CD95, stimulated by cancer-produced CD95L, for optimal growth. Consistently, loss of CD95 in mouse models of ovarian cancer and liver cancer reduces cancer incidence as well as the size of the tumours. The tumorigenic activity of CD95 is mediated by a pathway involving JNK and Jun. These results demonstrate that CD95 has a growth-promoting role during tumorigenesis and indicate that efforts to inhibit its activity rather than to enhance it should be considered during cancer therapy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2879093/" 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/PMC2879093/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Lina -- Park, Sun-Mi -- Tumanov, Alexei V -- Hau, Annika -- Sawada, Kenjiro -- Feig, Christine -- Turner, Jerrold R -- Fu, Yang-Xin -- Romero, Iris L -- Lengyel, Ernst -- Peter, Marcus E -- CA112240/CA/NCI NIH HHS/ -- K12 HD000849/HD/NICHD NIH HHS/ -- L30 CA153336/CA/NCI NIH HHS/ -- R01 CA095319/CA/NCI NIH HHS/ -- R01 CA11182/CA/NCI NIH HHS/ -- R01 CA112240/CA/NCI NIH HHS/ -- R01 CA112240-01A1/CA/NCI NIH HHS/ -- R01 CA112240-02/CA/NCI NIH HHS/ -- R01 CA112240-03/CA/NCI NIH HHS/ -- R01 CA112240-04/CA/NCI NIH HHS/ -- R01 CA112240-05/CA/NCI NIH HHS/ -- England -- Nature. 2010 May 27;465(7297):492-6. doi: 10.1038/nature09075.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Ben May Department for Cancer Research, The University of Chicago, 924 E 57th Street, Chicago, Illinois 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20505730" target="_blank"〉PubMed〈/a〉

    Description: The autism spectrum disorders (ASDs) are a group of conditions characterized by impairments in reciprocal social interaction and communication, and the presence of restricted and repetitive behaviours. Individuals with an ASD vary greatly in cognitive development, which can range from above average to intellectual disability. Although ASDs are known to be highly heritable ( approximately 90%), the underlying genetic determinants are still largely unknown. Here we analysed the genome-wide characteristics of rare (〈1% frequency) copy number variation in ASD using dense genotyping arrays. When comparing 996 ASD individuals of European ancestry to 1,287 matched controls, cases were found to carry a higher global burden of rare, genic copy number variants (CNVs) (1.19 fold, P = 0.012), especially so for loci previously implicated in either ASD and/or intellectual disability (1.69 fold, P = 3.4 x 10(-4)). Among the CNVs there were numerous de novo and inherited events, sometimes in combination in a given family, implicating many novel ASD genes such as SHANK2, SYNGAP1, DLGAP2 and the X-linked DDX53-PTCHD1 locus. We also discovered an enrichment of CNVs disrupting functional gene sets involved in cellular proliferation, projection and motility, and GTPase/Ras signalling. Our results reveal many new genetic and functional targets in ASD that may lead to final connected pathways.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3021798/"

    Description: Tumour metastasis is the primary cause of death of cancer patients. Development of new therapeutics preventing tumour metastasis is urgently needed. Migrastatin is a natural product secreted by Streptomyces, and synthesized migrastatin analogues such as macroketone are potent inhibitors of metastatic tumour cell migration, invasion and metastasis. Here we show that these migrastatin analogues target the actin-bundling protein fascin to inhibit its activity. X-ray crystal structural studies reveal that migrastatin analogues bind to one of the actin-binding sites on fascin. Our data demonstrate that actin cytoskeletal proteins such as fascin can be explored as new molecular targets for cancer treatment, in a similar manner to the microtubule protein tubulin.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2857318/" 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/PMC2857318/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Lin -- Yang, Shengyu -- Jakoncic, Jean -- Zhang, J Jillian -- Huang, Xin-Yun -- CA136837/CA/NCI NIH HHS/ -- R01 CA136837/CA/NCI NIH HHS/ -- R01 CA136837-01A1/CA/NCI NIH HHS/ -- England -- Nature. 2010 Apr 15;464(7291):1062-6. doi: 10.1038/nature08978.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, Cornell University Weill Medical College, New York, New York 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20393565" target="_blank"〉PubMed〈/a〉

    Description: Neurotransmitter/sodium symporters (NSSs) couple the uptake of neurotransmitter with one or more sodium ions, removing neurotransmitter from the synaptic cleft. NSSs are essential to the function of chemical synapses, are associated with multiple neurological diseases and disorders, and are the targets of therapeutic and illicit drugs. LeuT, a prokaryotic orthologue of the NSS family, is a model transporter for understanding the relationships between molecular mechanism and atomic structure in a broad range of sodium-dependent and sodium-independent secondary transporters. At present there is a controversy over whether there are one or two high-affinity substrate binding sites in LeuT. The first-reported crystal structure of LeuT, together with subsequent functional and structural studies, provided direct evidence for a single, high-affinity, centrally located substrate-binding site, defined as the S1 site. Recent binding, flux and molecular simulation studies, however, have been interpreted in terms of a model where there are two high-affinity binding sites: the central, S1, site and a second, the S2 site, located within the extracellular vestibule. Furthermore, it was proposed that the S1 and S2 sites are allosterically coupled such that occupancy of the S2 site is required for the cytoplasmic release of substrate from the S1 site. Here we address this controversy by performing direct measurement of substrate binding to wild-type LeuT and to S2 site mutants using isothermal titration calorimetry, equilibrium dialysis and scintillation proximity assays. In addition, we perform uptake experiments to determine whether the proposed allosteric coupling between the putative S2 site and the S1 site manifests itself in the kinetics of substrate flux. We conclude that LeuT harbours a single, centrally located, high-affinity substrate-binding site and that transport is well described by a simple, single-substrate kinetic mechanism.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3079577/" 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/PMC3079577/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Piscitelli, Chayne L -- Krishnamurthy, Harini -- Gouaux, Eric -- R37 MH070039/MH/NIMH NIH HHS/ -- R37 MH070039-07/MH/NIMH NIH HHS/ -- R37 MH070039-08/MH/NIMH NIH HHS/ -- T32 DK007680/DK/NIDDK NIH HHS/ -- T32 DK007680-17/DK/NIDDK NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Dec 23;468(7327):1129-32. doi: 10.1038/nature09581.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, Oregon Health and Science University, 3181 SW Sam Jackson Park Road, Portland, Oregon 97239, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21179170" target="_blank"〉PubMed〈/a〉

    Description: Sugar efflux transporters are essential for the maintenance of animal blood glucose levels, plant nectar production, and plant seed and pollen development. Despite broad biological importance, the identity of sugar efflux transporters has remained elusive. Using optical glucose sensors, we identified a new class of sugar transporters, named SWEETs, and show that at least six out of seventeen Arabidopsis, two out of over twenty rice and two out of seven homologues in Caenorhabditis elegans, and the single copy human protein, mediate glucose transport. Arabidopsis SWEET8 is essential for pollen viability, and the rice homologues SWEET11 and SWEET14 are specifically exploited by bacterial pathogens for virulence by means of direct binding of a bacterial effector to the SWEET promoter. Bacterial symbionts and fungal and bacterial pathogens induce the expression of different SWEET genes, indicating that the sugar efflux function of SWEET transporters is probably targeted by pathogens and symbionts for nutritional gain. The metazoan homologues may be involved in sugar efflux from intestinal, liver, epididymis and mammary cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3000469/" 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/PMC3000469/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Li-Qing -- Hou, Bi-Huei -- Lalonde, Sylvie -- Takanaga, Hitomi -- Hartung, Mara L -- Qu, Xiao-Qing -- Guo, Woei-Jiun -- Kim, Jung-Gun -- Underwood, William -- Chaudhuri, Bhavna -- Chermak, Diane -- Antony, Ginny -- White, Frank F -- Somerville, Shauna C -- Mudgett, Mary Beth -- Frommer, Wolf B -- 1R01DK079109/DK/NIDDK NIH HHS/ -- F32GM083439-02/GM/NIGMS NIH HHS/ -- R01 DK079109/DK/NIDDK NIH HHS/ -- R01 DK079109-01/DK/NIDDK NIH HHS/ -- R01 DK079109-02/DK/NIDDK NIH HHS/ -- R01 DK079109-03/DK/NIDDK NIH HHS/ -- R01 DK079109-03S1/DK/NIDDK NIH HHS/ -- R01 DK079109-04/DK/NIDDK NIH HHS/ -- R01 GM068886/GM/NIGMS NIH HHS/ -- ZR01GM06886-06A1/GM/NIGMS NIH HHS/ -- England -- Nature. 2010 Nov 25;468(7323):527-32. doi: 10.1038/nature09606.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, Carnegie Institution for Science, 260 Panama St, Stanford, California 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21107422" target="_blank"〉PubMed〈/a〉
