    Description: Tens of millions of people in south and southeast Asia routinely consume ground water that has unsafe arsenic levels. Arsenic is naturally derived from eroded Himalayan sediments, and is believed to enter solution following reductive release from solid phases under anaerobic conditions. However, the processes governing aqueous concentrations and locations of arsenic release to pore water remain unresolved, limiting our ability to predict arsenic concentrations spatially (between wells) and temporally (future concentrations) and to assess the impact of human activities on the arsenic problem. This uncertainty is partly attributed to a poor understanding of groundwater flow paths altered by extensive irrigation pumping in the Ganges-Brahmaputra delta, where most research has focused. Here, using hydrologic and (bio)geochemical measurements, we show that on the minimally disturbed Mekong delta of Cambodia, arsenic is released from near-surface, river-derived sediments and transported, on a centennial timescale, through the underlying aquifer back to the river. Owing to similarities in geologic deposition, aquifer source rock and regional hydrologic gradients, our results represent a model for understanding pre-disturbance conditions for other major deltas in Asia. Furthermore, the observation of strong hydrologic influence on arsenic behaviour indicates that release and transport of arsenic are sensitive to continuing and impending anthropogenic disturbances. In particular, groundwater pumping for irrigation, changes in agricultural practices, sediment excavation, levee construction and upstream dam installations will alter the hydraulic regime and/or arsenic source material and, by extension, influence groundwater arsenic concentrations and the future of this health problem.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Polizzotto, Matthew L -- Kocar, Benjamin D -- Benner, Shawn G -- Sampson, Michael -- Fendorf, Scott -- England -- Nature. 2008 Jul 24;454(7203):505-8. doi: 10.1038/nature07093.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Earth Sciences, Stanford University, Stanford, California 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18650922" target="_blank"〉PubMed〈/a〉

    Description: The existence of a small population of 'cancer-initiating cells' responsible for tumour maintenance has been firmly demonstrated in leukaemia. This concept is currently being tested in solid tumours. Leukaemia-initiating cells, particularly those that are in a quiescent state, are thought to be resistant to chemotherapy and targeted therapies, resulting in disease relapse. Chronic myeloid leukaemia is a paradigmatic haematopoietic stem cell disease in which the leukaemia-initiating-cell pool is not eradicated by current therapy, leading to disease relapse on drug discontinuation. Here we define the critical role of the promyelocytic leukaemia protein (PML) tumour suppressor in haematopoietic stem cell maintenance, and present a new therapeutic approach for targeting quiescent leukaemia-initiating cells and possibly cancer-initiating cells by pharmacological inhibition of PML.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2712082/" 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/PMC2712082/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ito, Keisuke -- Bernardi, Rosa -- Morotti, Alessandro -- Matsuoka, Sahoko -- Saglio, Giuseppe -- Ikeda, Yasuo -- Rosenblatt, Jacalyn -- Avigan, David E -- Teruya-Feldstein, Julie -- Pandolfi, Pier Paolo -- K99 CA139009/CA/NCI NIH HHS/ -- R00 CA139009/CA/NCI NIH HHS/ -- R37 CA071692/CA/NCI NIH HHS/ -- R37 CA071692-12/CA/NCI NIH HHS/ -- England -- Nature. 2008 Jun 19;453(7198):1072-8. doi: 10.1038/nature07016.

    Description: Our decisions are guided by information learnt from our environment. This information may come via personal experiences of reward, but also from the behaviour of social partners. Social learning is widely held to be distinct from other forms of learning in its mechanism and neural implementation; it is often assumed to compete with simpler mechanisms, such as reward-based associative learning, to drive behaviour. Recently, neural signals have been observed during social exchange reminiscent of signals seen in studies of associative learning. Here we demonstrate that social information may be acquired using the same associative processes assumed to underlie reward-based learning. We find that key computational variables for learning in the social and reward domains are processed in a similar fashion, but in parallel neural processing streams. Two neighbouring divisions of the anterior cingulate cortex were central to learning about social and reward-based information, and for determining the extent to which each source of information guides behaviour. When making a decision, however, the information learnt using these parallel streams was combined within ventromedial prefrontal cortex. These findings suggest that human social valuation can be realized by means of the same associative processes previously established for learning other, simpler, features of the environment.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2605577/" 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/PMC2605577/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Behrens, Timothy E J -- Hunt, Laurence T -- Woolrich, Mark W -- Rushworth, Matthew F S -- G0501316/Medical Research Council/United Kingdom -- G0501316(75487)/Medical Research Council/United Kingdom -- G0600994/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2008 Nov 13;456(7219):245-9. doi: 10.1038/nature07538.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉FMRIB Centre, University of Oxford, John Radcliffe Hospital, Oxford OX3 9DU, UK. behrens@fmrib.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19005555" target="_blank"〉PubMed〈/a〉

    Description: A common hallmark of human cancers is the overexpression of telomerase, a ribonucleoprotein complex that is responsible for maintaining the length and integrity of chromosome ends. Telomere length deregulation and telomerase activation is an early, and perhaps necessary, step in cancer cell evolution. Here we present the high-resolution structure of the Tribolium castaneum catalytic subunit of telomerase, TERT. The protein consists of three highly conserved domains, organized into a ring-like structure that shares common features with retroviral reverse transcriptases, viral RNA polymerases and B-family DNA polymerases. Domain organization places motifs implicated in substrate binding and catalysis in the interior of the ring, which can accommodate seven to eight bases of double-stranded nucleic acid. Modelling of an RNA-DNA heteroduplex in the interior of this ring demonstrates a perfect fit between the protein and the nucleic acid substrate, and positions the 3'-end of the DNA primer at the active site of the enzyme, providing evidence for the formation of an active telomerase elongation complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gillis, Andrew J -- Schuller, Anthony P -- Skordalakes, Emmanuel -- England -- Nature. 2008 Oct 2;455(7213):633-7. doi: 10.1038/nature07283.

    Description: Glycogen synthase kinase 3 (GSK3) is a multifunctional serine/threonine kinase that participates in numerous signalling pathways involved in diverse physiological processes. Several of these pathways are implicated in disease pathogenesis, which has prompted efforts to develop GSK3-specific inhibitors for therapeutic applications. However, before now, there has been no strong rationale for targeting GSK3 in malignancies. Here we report pharmacological, physiological and genetic studies that demonstrate an oncogenic requirement for GSK3 in the maintenance of a specific subtype of poor prognosis human leukaemia, genetically defined by mutations of the MLL proto-oncogene. In contrast to its previously characterized roles in suppression of neoplasia-associated signalling pathways, GSK3 paradoxically supports MLL leukaemia cell proliferation and transformation by a mechanism that ultimately involves destabilization of the cyclin-dependent kinase inhibitor p27(Kip1). Inhibition of GSK3 in a preclinical murine model of MLL leukaemia provides promising evidence of efficacy and earmarks GSK3 as a candidate cancer drug target.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4084721/" 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/PMC4084721/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Zhong -- Smith, Kevin S -- Murphy, Mark -- Piloto, Obdulio -- Somervaille, Tim C P -- Cleary, Michael L -- CA116606/CA/NCI NIH HHS/ -- CA55029/CA/NCI NIH HHS/ -- R01 CA055029/CA/NCI NIH HHS/ -- R01 CA116606/CA/NCI NIH HHS/ -- England -- Nature. 2008 Oct 30;455(7217):1205-9. doi: 10.1038/nature07284.

    Description: Genome-wide patterns of variation across individuals provide a powerful source of data for uncovering the history of migration, range expansion, and adaptation of the human species. However, high-resolution surveys of variation in genotype, haplotype and copy number have generally focused on a small number of population groups. Here we report the analysis of high-quality genotypes at 525,910 single-nucleotide polymorphisms (SNPs) and 396 copy-number-variable loci in a worldwide sample of 29 populations. Analysis of SNP genotypes yields strongly supported fine-scale inferences about population structure. Increasing linkage disequilibrium is observed with increasing geographic distance from Africa, as expected under a serial founder effect for the out-of-Africa spread of human populations. New approaches for haplotype analysis produce inferences about population structure that complement results based on unphased SNPs. Despite a difference from SNPs in the frequency spectrum of the copy-number variants (CNVs) detected--including a comparatively large number of CNVs in previously unexamined populations from Oceania and the Americas--the global distribution of CNVs largely accords with population structure analyses for SNP data sets of similar size. Our results produce new inferences about inter-population variation, support the utility of CNVs in human population-genetic research, and serve as a genomic resource for human-genetic studies in diverse worldwide populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jakobsson, Mattias -- Scholz, Sonja W -- Scheet, Paul -- Gibbs, J Raphael -- VanLiere, Jenna M -- Fung, Hon-Chung -- Szpiech, Zachary A -- Degnan, James H -- Wang, Kai -- Guerreiro, Rita -- Bras, Jose M -- Schymick, Jennifer C -- Hernandez, Dena G -- Traynor, Bryan J -- Simon-Sanchez, Javier -- Matarin, Mar -- Britton, Angela -- van de Leemput, Joyce -- Rafferty, Ian -- Bucan, Maja -- Cann, Howard M -- Hardy, John A -- Rosenberg, Noah A -- Singleton, Andrew B -- G0701075/Medical Research Council/United Kingdom -- MR/K01417X/1/Medical Research Council/United Kingdom -- Intramural NIH HHS/ -- England -- Nature. 2008 Feb 21;451(7181):998-1003. doi: 10.1038/nature06742.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Computational Medicine and Biology, University of Michigan, Ann Arbor, Michigan 48109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18288195" target="_blank"〉PubMed〈/a〉

    Description: Neuroblastoma, a tumour derived from the peripheral sympathetic nervous system, is one of the most frequent solid tumours in childhood. It usually occurs sporadically but familial cases are observed, with a subset of cases occurring in association with congenital malformations of the neural crest being linked to germline mutations of the PHOX2B gene. Here we conducted genome-wide comparative genomic hybridization analysis on a large series of neuroblastomas. Copy number increase at the locus encoding the anaplastic lymphoma kinase (ALK) tyrosine kinase receptor was observed recurrently. One particularly informative case presented a high-level gene amplification that was strictly limited to ALK, indicating that this gene may contribute on its own to neuroblastoma development. Through subsequent direct sequencing of cell lines and primary tumour DNAs we identified somatic mutations of the ALK kinase domain that mainly clustered in two hotspots. Germline mutations were observed in two neuroblastoma families, indicating that ALK is a neuroblastoma predisposition gene. Mutated ALK proteins were overexpressed, hyperphosphorylated and showed constitutive kinase activity. The knockdown of ALK expression in ALK-mutated cells, but also in cell lines overexpressing a wild-type ALK, led to a marked decrease of cell proliferation. Altogether, these data identify ALK as a critical player in neuroblastoma development that may hence represent a very attractive therapeutic target in this disease that is still frequently fatal with current treatments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Janoueix-Lerosey, Isabelle -- Lequin, Delphine -- Brugieres, Laurence -- Ribeiro, Agnes -- de Pontual, Loic -- Combaret, Valerie -- Raynal, Virginie -- Puisieux, Alain -- Schleiermacher, Gudrun -- Pierron, Gaelle -- Valteau-Couanet, Dominique -- Frebourg, Thierry -- Michon, Jean -- Lyonnet, Stanislas -- Amiel, Jeanne -- Delattre, Olivier -- England -- Nature. 2008 Oct 16;455(7215):967-70. doi: 10.1038/nature07398.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut Curie, Centre de Recherche, and Inserm, U830, 26 rue d'Ulm, Paris F-75248, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18923523" target="_blank"〉PubMed〈/a〉

    Description: The integrity of the cornea, the most anterior part of the eye, is indispensable for vision. Forty-five million individuals worldwide are bilaterally blind and another 135 million have severely impaired vision in both eyes because of loss of corneal transparency; treatments range from local medications to corneal transplants, and more recently to stem cell therapy. The corneal epithelium is a squamous epithelium that is constantly renewing, with a vertical turnover of 7 to 14 days in many mammals. Identification of slow cycling cells (label-retaining cells) in the limbus of the mouse has led to the notion that the limbus is the niche for the stem cells responsible for the long-term renewal of the cornea; hence, the corneal epithelium is supposedly renewed by cells generated at and migrating from the limbus, in marked opposition to other squamous epithelia in which each resident stem cell has in charge a limited area of epithelium. Here we show that the corneal epithelium of the mouse can be serially transplanted, is self-maintained and contains oligopotent stem cells with the capacity to generate goblet cells if provided with a conjunctival environment. Furthermore, the entire ocular surface of the pig, including the cornea, contains oligopotent stem cells (holoclones) with the capacity to generate individual colonies of corneal and conjunctival cells. Therefore, the limbus is not the only niche for corneal stem cells and corneal renewal is not different from other squamous epithelia. We propose a model that unifies our observations with the literature and explains why the limbal region is enriched in stem cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Majo, Francois -- Rochat, Ariane -- Nicolas, Michael -- Jaoude, Georges Abou -- Barrandon, Yann -- England -- Nature. 2008 Nov 13;456(7219):250-4. doi: 10.1038/nature07406.

    Description: We present a draft genome sequence of the platypus, Ornithorhynchus anatinus. This monotreme exhibits a fascinating combination of reptilian and mammalian characters. For example, platypuses have a coat of fur adapted to an aquatic lifestyle; platypus females lactate, yet lay eggs; and males are equipped with venom similar to that of reptiles. Analysis of the first monotreme genome aligned these features with genetic innovations. We find that reptile and platypus venom proteins have been co-opted independently from the same gene families; milk protein genes are conserved despite platypuses laying eggs; and immune gene family expansions are directly related to platypus biology. Expansions of protein, non-protein-coding RNA and microRNA families, as well as repeat elements, are identified. Sequencing of this genome now provides a valuable resource for deep mammalian comparative analyses, as well as for monotreme biology and conservation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2803040/" 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/PMC2803040/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warren, Wesley C -- Hillier, LaDeana W -- Marshall Graves, Jennifer A -- Birney, Ewan -- Ponting, Chris P -- Grutzner, Frank -- Belov, Katherine -- Miller, Webb -- Clarke, Laura -- Chinwalla, Asif T -- Yang, Shiaw-Pyng -- Heger, Andreas -- Locke, Devin P -- Miethke, Pat -- Waters, Paul D -- Veyrunes, Frederic -- Fulton, Lucinda -- Fulton, Bob -- Graves, Tina -- Wallis, John -- Puente, Xose S -- Lopez-Otin, Carlos -- Ordonez, Gonzalo R -- Eichler, Evan E -- Chen, Lin -- Cheng, Ze -- Deakin, Janine E -- Alsop, Amber -- Thompson, Katherine -- Kirby, Patrick -- Papenfuss, Anthony T -- Wakefield, Matthew J -- Olender, Tsviya -- Lancet, Doron -- Huttley, Gavin A -- Smit, Arian F A -- Pask, Andrew -- Temple-Smith, Peter -- Batzer, Mark A -- Walker, Jerilyn A -- Konkel, Miriam K -- Harris, Robert S -- Whittington, Camilla M -- Wong, Emily S W -- Gemmell, Neil J -- Buschiazzo, Emmanuel -- Vargas Jentzsch, Iris M -- Merkel, Angelika -- Schmitz, Juergen -- Zemann, Anja -- Churakov, Gennady -- Kriegs, Jan Ole -- Brosius, Juergen -- Murchison, Elizabeth P -- Sachidanandam, Ravi -- Smith, Carly -- Hannon, Gregory J -- Tsend-Ayush, Enkhjargal -- McMillan, Daniel -- Attenborough, Rosalind -- Rens, Willem -- Ferguson-Smith, Malcolm -- Lefevre, Christophe M -- Sharp, Julie A -- Nicholas, Kevin R -- Ray, David A -- Kube, Michael -- Reinhardt, Richard -- Pringle, Thomas H -- Taylor, James -- Jones, Russell C -- Nixon, Brett -- Dacheux, Jean-Louis -- Niwa, Hitoshi -- Sekita, Yoko -- Huang, Xiaoqiu -- Stark, Alexander -- Kheradpour, Pouya -- Kellis, Manolis -- Flicek, Paul -- Chen, Yuan -- Webber, Caleb -- Hardison, Ross -- Nelson, Joanne -- Hallsworth-Pepin, Kym -- Delehaunty, Kim -- Markovic, Chris -- Minx, Pat -- Feng, Yucheng -- Kremitzki, Colin -- Mitreva, Makedonka -- Glasscock, Jarret -- Wylie, Todd -- Wohldmann, Patricia -- Thiru, Prathapan -- Nhan, Michael N -- Pohl, Craig S -- Smith, Scott M -- Hou, Shunfeng -- Nefedov, Mikhail -- de Jong, Pieter J -- Renfree, Marilyn B -- Mardis, Elaine R -- Wilson, Richard K -- 062023/Wellcome Trust/United Kingdom -- HG002238/HG/NHGRI NIH HHS/ -- MC_U137761446/Medical Research Council/United Kingdom -- P01 CA013106/CA/NCI NIH HHS/ -- P01 CA013106-37/CA/NCI NIH HHS/ -- R01 GM59290/GM/NIGMS NIH HHS/ -- R01 HG002939/HG/NHGRI NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01 HG004037-02/HG/NHGRI NIH HHS/ -- R01HG02385/HG/NHGRI NIH HHS/ -- Medical Research Council/United Kingdom -- England -- Nature. 2008 May 8;453(7192):175-83. doi: 10.1038/nature06936.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genome Sequencing Center, Washington University School of Medicine, Campus Box 8501, 4444 Forest Park Avenue, St Louis, Missouri 63108, USA. wwarren@wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18464734" target="_blank"〉PubMed〈/a〉

    Description: Continuous turnover of epithelia is ensured by the extensive self-renewal capacity of tissue-specific stem cells. Similarly, epithelial tumour maintenance relies on cancer stem cells (CSCs), which co-opt stem cell properties. For most tumours, the cellular origin of these CSCs and regulatory pathways essential for sustaining stemness have not been identified. In murine skin, follicular morphogenesis is driven by bulge stem cells that specifically express CD34. Here we identify a population of cells in early epidermal tumours characterized by phenotypic and functional similarities to normal bulge skin stem cells. This population contains CSCs, which are the only cells with tumour initiation properties. Transplants derived from these CSCs preserve the hierarchical organization of the primary tumour. We describe beta-catenin signalling as being essential in sustaining the CSC phenotype. Ablation of the beta-catenin gene results in the loss of CSCs and complete tumour regression. In addition, we provide evidence for the involvement of increased beta-catenin signalling in malignant human squamous cell carcinomas. Because Wnt/beta-catenin signalling is not essential for normal epidermal homeostasis, such a mechanistic difference may thus be targeted to eliminate CSCs and consequently eradicate squamous cell carcinomas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Malanchi, Ilaria -- Peinado, Hector -- Kassen, Deepika -- Hussenet, Thomas -- Metzger, Daniel -- Chambon, Pierre -- Huber, Marcel -- Hohl, Daniel -- Cano, Amparo -- Birchmeier, Walter -- Huelsken, Joerg -- England -- Nature. 2008 Apr 3;452(7187):650-3. doi: 10.1038/nature06835.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ecole Polytechnique Federale de Lausanne/ISREC (Swiss Institute for Experimental Cancer Research) and National Center of Competence in Research Molecular Oncology, Chemin des Boveresses 155, 1066 Epalinges, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18385740" target="_blank"〉PubMed〈/a〉

    Description: The nuclear receptors known as PPARs and LXRs are lipid-activated transcription factors that have emerged as key regulators of lipid metabolism and inflammation. PPARs and LXRs are activated by non-esterified fatty acids and cholesterol metabolites, respectively, and both exert positive and negative control over the expression of a range of metabolic and inflammatory genes. The ability of these nuclear receptors to integrate metabolic and inflammatory signalling makes them attractive targets for intervention in human metabolic diseases, such as atherosclerosis and type 2 diabetes, as well as for the modulation of inflammation and immune responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bensinger, Steven J -- Tontonoz, Peter -- HL30568/HL/NHLBI NIH HHS/ -- HL66088/HL/NHLBI NIH HHS/ -- RR021975/RR/NCRR NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2008 Jul 24;454(7203):470-7. doi: 10.1038/nature07202.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Pathology and Laboratory Medicine, David Geffen School of Medicine, University of California, Los Angeles, 675 Charles E.

    Description: DNA sequence information underpins genetic research, enabling discoveries of important biological or medical benefit. Sequencing projects have traditionally used long (400-800 base pair) reads, but the existence of reference sequences for the human and many other genomes makes it possible to develop new, fast approaches to re-sequencing, whereby shorter reads are compared to a reference to identify intraspecies genetic variation. Here we report an approach that generates several billion bases of accurate nucleotide sequence per experiment at low cost. Single molecules of DNA are attached to a flat surface, amplified in situ and used as templates for synthetic sequencing with fluorescent reversible terminator deoxyribonucleotides. Images of the surface are analysed to generate high-quality sequence. We demonstrate application of this approach to human genome sequencing on flow-sorted X chromosomes and then scale the approach to determine the genome sequence of a male Yoruba from Ibadan, Nigeria. We build an accurate consensus sequence from 〉30x average depth of paired 35-base reads. We characterize four million single-nucleotide polymorphisms and four hundred thousand structural variants, many of which were previously unknown. Our approach is effective for accurate, rapid and economical whole-genome re-sequencing and many other biomedical applications.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2581791/" 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/PMC2581791/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bentley, David R -- Balasubramanian, Shankar -- Swerdlow, Harold P -- Smith, Geoffrey P -- Milton, John -- Brown, Clive G -- Hall, Kevin P -- Evers, Dirk J -- Barnes, Colin L -- Bignell, Helen R -- Boutell, Jonathan M -- Bryant, Jason -- Carter, Richard J -- Keira Cheetham, R -- Cox, Anthony J -- Ellis, Darren J -- Flatbush, Michael R -- Gormley, Niall A -- Humphray, Sean J -- Irving, Leslie J -- Karbelashvili, Mirian S -- Kirk, Scott M -- Li, Heng -- Liu, Xiaohai -- Maisinger, Klaus S -- Murray, Lisa J -- Obradovic, Bojan -- Ost, Tobias -- Parkinson, Michael L -- Pratt, Mark R -- Rasolonjatovo, Isabelle M J -- Reed, Mark T -- Rigatti, Roberto -- Rodighiero, Chiara -- Ross, Mark T -- Sabot, Andrea -- Sankar, Subramanian V -- Scally, Aylwyn -- Schroth, Gary P -- Smith, Mark E -- Smith, Vincent P -- Spiridou, Anastassia -- Torrance, Peta E -- Tzonev, Svilen S -- Vermaas, Eric H -- Walter, Klaudia -- Wu, Xiaolin -- Zhang, Lu -- Alam, Mohammed D -- Anastasi, Carole -- Aniebo, Ify C -- Bailey, David M D -- Bancarz, Iain R -- Banerjee, Saibal -- Barbour, Selena G -- Baybayan, Primo A -- Benoit, Vincent A -- Benson, Kevin F -- Bevis, Claire -- Black, Phillip J -- Boodhun, Asha -- Brennan, Joe S -- Bridgham, John A -- Brown, Rob C -- Brown, Andrew A -- Buermann, Dale H -- Bundu, Abass A -- Burrows, James C -- Carter, Nigel P -- Castillo, Nestor -- Chiara E Catenazzi, Maria -- Chang, Simon -- Neil Cooley, R -- Crake, Natasha R -- Dada, Olubunmi O -- Diakoumakos, Konstantinos D -- Dominguez-Fernandez, Belen -- Earnshaw, David J -- Egbujor, Ugonna C -- Elmore, David W -- Etchin, Sergey S -- Ewan, Mark R -- Fedurco, Milan -- Fraser, Louise J -- Fuentes Fajardo, Karin V -- Scott Furey, W -- George, David -- Gietzen, Kimberley J -- Goddard, Colin P -- Golda, George S -- Granieri, Philip A -- Green, David E -- Gustafson, David L -- Hansen, Nancy F -- Harnish, Kevin -- Haudenschild, Christian D -- Heyer, Narinder I -- Hims, Matthew M -- Ho, Johnny T -- Horgan, Adrian M -- Hoschler, Katya -- Hurwitz, Steve -- Ivanov, Denis V -- Johnson, Maria Q -- James, Terena -- Huw Jones, T A -- Kang, Gyoung-Dong -- Kerelska, Tzvetana H -- Kersey, Alan D -- Khrebtukova, Irina -- Kindwall, Alex P -- Kingsbury, Zoya -- Kokko-Gonzales, Paula I -- Kumar, Anil -- Laurent, Marc A -- Lawley, Cynthia T -- Lee, Sarah E -- Lee, Xavier -- Liao, Arnold K -- Loch, Jennifer A -- Lok, Mitch -- Luo, Shujun -- Mammen, Radhika M -- Martin, John W -- McCauley, Patrick G -- McNitt, Paul -- Mehta, Parul -- Moon, Keith W -- Mullens, Joe W -- Newington, Taksina -- Ning, Zemin -- Ling Ng, Bee -- Novo, Sonia M -- O'Neill, Michael J -- Osborne, Mark A -- Osnowski, Andrew -- Ostadan, Omead -- Paraschos, Lambros L -- Pickering, Lea -- Pike, Andrew C -- Pike, Alger C -- Chris Pinkard, D -- Pliskin, Daniel P -- Podhasky, Joe -- Quijano, Victor J -- Raczy, Come -- Rae, Vicki H -- Rawlings, Stephen R -- Chiva Rodriguez, Ana -- Roe, Phyllida M -- Rogers, John -- Rogert Bacigalupo, Maria C -- Romanov, Nikolai -- Romieu, Anthony -- Roth, Rithy K -- Rourke, Natalie J -- Ruediger, Silke T -- Rusman, Eli -- Sanches-Kuiper, Raquel M -- Schenker, Martin R -- Seoane, Josefina M -- Shaw, Richard J -- Shiver, Mitch K -- Short, Steven W -- Sizto, Ning L -- Sluis, Johannes P -- Smith, Melanie A -- Ernest Sohna Sohna, Jean -- Spence, Eric J -- Stevens, Kim -- Sutton, Neil -- Szajkowski, Lukasz -- Tregidgo, Carolyn L -- Turcatti, Gerardo -- Vandevondele, Stephanie -- Verhovsky, Yuli -- Virk, Selene M -- Wakelin, Suzanne -- Walcott, Gregory C -- Wang, Jingwen -- Worsley, Graham J -- Yan, Juying -- Yau, Ling -- Zuerlein, Mike -- Rogers, Jane -- Mullikin, James C -- Hurles, Matthew E -- McCooke, Nick J -- West, John S -- Oaks, Frank L -- Lundberg, Peter L -- Klenerman, David -- Durbin, Richard -- Smith, Anthony J -- B05823/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0701805/Medical Research Council/United Kingdom -- MOL04534/Biotechnology and Biological Sciences Research Council/United Kingdom -- Z01 HG200330-03/Intramural NIH HHS/ -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2008 Nov 6;456(7218):53-9. doi: 10.1038/nature07517.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Illumina Cambridge Ltd.

    Description: Human cytomegalovirus (HCMV) is a ubiquitous human herpesvirus that can cause life-threatening disease in the fetus and the immunocompromised host. Upon attachment to the cell, the virus induces robust inflammatory, interferon- and growth-factor-like signalling. The mechanisms facilitating viral entry and gene expression are not clearly understood. Here we show that platelet-derived growth factor-alpha receptor (PDGFR-alpha) is specifically phosphorylated by both laboratory and clinical isolates of HCMV in various human cell types, resulting in activation of the phosphoinositide-3-kinase (PI(3)K) signalling pathway. Upon stimulation by HCMV, tyrosine-phosphorylated PDGFR-alpha associated with the p85 regulatory subunit of PI(3)K and induced protein kinase B (also known as Akt) phosphorylation, similar to the genuine ligand, PDGF-AA. Cells in which PDGFR-alpha was genetically deleted or functionally blocked were non-permissive to HCMV entry, viral gene expression or infectious virus production. Re-introducing human PDGFRA gene into knockout cells restored susceptibility to viral entry and essential viral gene expression. Blockade of receptor function with a humanized PDGFR-alpha blocking antibody (IMC-3G3) or targeted inhibition of its kinase activity with a small molecule (Gleevec) completely inhibited HCMV viral internalization and gene expression in human epithelial, endothelial and fibroblast cells. Viral entry in cells harbouring endogenous PDGFR-alpha was competitively inhibited by pretreatment with PDGF-AA. We further demonstrate that HCMV glycoprotein B directly interacts with PDGFR-alpha, resulting in receptor tyrosine phosphorylation, and that glycoprotein B neutralizing antibodies inhibit HCMV-induced PDGFR-alpha phosphorylation. Taken together, these data indicate that PDGFR-alpha is a critical receptor required for HCMV infection, and thus a target for novel anti-viral therapies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Soroceanu, Liliana -- Akhavan, Armin -- Cobbs, Charles S -- England -- Nature. 2008 Sep 18;455(7211):391-5. doi: 10.1038/nature07209.

    Description: Nuclear exclusion of the PTEN (phosphatase and tensin homologue deleted in chromosome 10) tumour suppressor has been associated with cancer progression. However, the mechanisms leading to this aberrant PTEN localization in human cancers are currently unknown. We have previously reported that ubiquitinylation of PTEN at specific lysine residues regulates its nuclear-cytoplasmic partitioning. Here we show that functional promyelocytic leukaemia protein (PML) nuclear bodies co-ordinate PTEN localization by opposing the action of a previously unknown PTEN-deubiquitinylating enzyme, herpesvirus-associated ubiquitin-specific protease (HAUSP, also known as USP7), and that the integrity of this molecular framework is required for PTEN to be able to enter the nucleus. We find that PTEN is aberrantly localized in acute promyelocytic leukaemia, in which PML function is disrupted by the PML-RARalpha fusion oncoprotein. Remarkably, treatment with drugs that trigger PML-RARalpha degradation, such as all-trans retinoic acid or arsenic trioxide, restore nuclear PTEN. We demonstrate that PML opposes the activity of HAUSP towards PTEN through a mechanism involving the adaptor protein DAXX (death domain-associated protein). In support of this paradigm, we show that HAUSP is overexpressed in human prostate cancer and is associated with PTEN nuclear exclusion. Thus, our results delineate a previously unknown PML-DAXX-HAUSP molecular network controlling PTEN deubiquitinylation and trafficking, which is perturbed by oncogenic cues in human cancer, in turn defining a new deubiquitinylation-dependent model for PTEN subcellular compartmentalization.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3398484/" 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/PMC3398484/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Song, Min Sup -- Salmena, Leonardo -- Carracedo, Arkaitz -- Egia, Ainara -- Lo-Coco, Francesco -- Teruya-Feldstein, Julie -- Pandolfi, Pier Paolo -- P50 CA092629/CA/NCI NIH HHS/ -- P50 CA092629-01/CA/NCI NIH HHS/ -- R01 CA082328/CA/NCI NIH HHS/ -- England -- Nature. 2008 Oct 9;455(7214):813-7. doi: 10.1038/nature07290.

    Description: On activation by receptors, the ubiquitously expressed class IA isoforms (p110alpha and p110beta) of phosphatidylinositol-3-OH kinase (PI(3)K) generate lipid second messengers, which initiate multiple signal transduction cascades. Recent studies have demonstrated specific functions for p110alpha in growth factor and insulin signalling. To probe for distinct functions of p110beta, we constructed conditional knockout mice. Here we show that ablation of p110beta in the livers of the resulting mice leads to impaired insulin sensitivity and glucose homeostasis, while having little effect on phosphorylation of Akt, suggesting the involvement of a kinase-independent role of p110beta in insulin metabolic action. Using established mouse embryonic fibroblasts, we found that removal of p110beta also had little effect on Akt phosphorylation in response to stimulation by insulin and epidermal growth factor, but resulted in retarded cell proliferation. Reconstitution of p110beta-null cells with a wild-type or kinase-dead allele of p110beta demonstrated that p110beta possesses kinase-independent functions in regulating cell proliferation and trafficking. However, the kinase activity of p110beta was required for G-protein-coupled receptor signalling triggered by lysophosphatidic acid and had a function in oncogenic transformation. Most strikingly, in an animal model of prostate tumour formation induced by Pten loss, ablation of p110beta (also known as Pik3cb), but not that of p110alpha (also known as Pik3ca), impeded tumorigenesis with a concomitant diminution of Akt phosphorylation. Taken together, our findings demonstrate both kinase-dependent and kinase-independent functions for p110beta, and strongly indicate the kinase-dependent functions of p110beta as a promising target in cancer therapy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2750091/" 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/PMC2750091/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jia, Shidong -- Liu, Zhenning -- Zhang, Sen -- Liu, Pixu -- Zhang, Lei -- Lee, Sang Hyun -- Zhang, Jing -- Signoretti, Sabina -- Loda, Massimo -- Roberts, Thomas M -- Zhao, Jean J -- P01 CA050661/CA/NCI NIH HHS/ -- P01 CA050661-200001/CA/NCI NIH HHS/ -- P01 CA089021/CA/NCI NIH HHS/ -- P01 CA089021-06A1/CA/NCI NIH HHS/ -- P50 CA089393/CA/NCI NIH HHS/ -- P50 CA089393-08S1/CA/NCI NIH HHS/ -- P50 CA090381/CA/NCI NIH HHS/ -- P50 CA090381-05/CA/NCI NIH HHS/ -- R01 CA030002/CA/NCI NIH HHS/ -- R01 CA030002-27/CA/NCI NIH HHS/ -- R01 CA134502/CA/NCI NIH HHS/ -- R01 CA134502-01/CA/NCI NIH HHS/ -- England -- Nature. 2008 Aug 7;454(7205):776-9. doi: 10.1038/nature07091.

    Description: The mediators and cellular effectors of inflammation are important constituents of the local environment of tumours. In some types of cancer, inflammatory conditions are present before a malignant change occurs. Conversely, in other types of cancer, an oncogenic change induces an inflammatory microenvironment that promotes the development of tumours. Regardless of its origin, 'smouldering' inflammation in the tumour microenvironment has many tumour-promoting effects. It aids in the proliferation and survival of malignant cells, promotes angiogenesis and metastasis, subverts adaptive immune responses, and alters responses to hormones and chemotherapeutic agents. The molecular pathways of this cancer-related inflammation are now being unravelled, resulting in the identification of new target molecules that could lead to improved diagnosis and treatment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mantovani, Alberto -- Allavena, Paola -- Sica, Antonio -- Balkwill, Frances -- G0501974/Medical Research Council/United Kingdom -- Cancer Research UK/United Kingdom -- Medical Research Council/United Kingdom -- England -- Nature. 2008 Jul 24;454(7203):436-44. doi: 10.1038/nature07205.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Istituto Clinico Humanitas IRCCS, Via Manzoni 56, Rozzano, 20089 Milan, Italy. alberto.mantovani@humanitas.it〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18650914" target="_blank"〉PubMed〈/a〉

    Description: New technologies for imaging molecules, particularly optical technologies, are increasingly being used to understand the complexity, diversity and in vivo behaviour of cancers. 'Omic' approaches are providing comprehensive 'snapshots' of biological indicators, or biomarkers, of cancer, but imaging can take this information a step further, showing the activity of these markers in vivo and how their location changes over time. Advances in experimental and clinical imaging are likely to improve how cancer is understood at a systems level and, ultimately, should enable doctors not only to locate tumours but also to assess the activity of the biological processes within these tumours and to provide 'on the spot' treatment.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2708079/" 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/PMC2708079/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weissleder, Ralph -- Pittet, Mikael J -- P01 CA069246/CA/NCI NIH HHS/ -- P01 CA069246-070006/CA/NCI NIH HHS/ -- P50 CA086355/CA/NCI NIH HHS/ -- P50 CA086355-01/CA/NCI NIH HHS/ -- U24 CA092782/CA/NCI NIH HHS/ -- U24 CA092782-07/CA/NCI NIH HHS/ -- England -- Nature. 2008 Apr 3;452(7187):580-9. doi: 10.1038/nature06917.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Systems Biology, Massachusetts General Hospital, 185 Cambridge Street, CPZN 5206, Boston, Massachusetts 02114, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18385732" target="_blank"〉PubMed〈/a〉

    Description: Obesity is increasing in an epidemic manner in most countries and constitutes a public health problem by enhancing the risk for cardiovascular disease and metabolic disorders such as type 2 diabetes. Owing to the increase in obesity, life expectancy may start to decrease in developed countries for the first time in recent history. The factors determining fat mass in adult humans are not fully understood, but increased lipid storage in already developed fat cells (adipocytes) is thought to be most important. Here we show that adipocyte number is a major determinant for the fat mass in adults. However, the number of fat cells stays constant in adulthood in lean and obese individuals, even after marked weight loss, indicating that the number of adipocytes is set during childhood and adolescence. To establish the dynamics within the stable population of adipocytes in adults, we have measured adipocyte turnover by analysing the integration of 14C derived from nuclear bomb tests in genomic DNA. Approximately 10% of fat cells are renewed annually at all adult ages and levels of body mass index. Neither adipocyte death nor generation rate is altered in early onset obesity, suggesting a tight regulation of fat cell number in this condition during adulthood. The high turnover of adipocytes establishes a new therapeutic target for pharmacological intervention in obesity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spalding, Kirsty L -- Arner, Erik -- Westermark, Pal O -- Bernard, Samuel -- Buchholz, Bruce A -- Bergmann, Olaf -- Blomqvist, Lennart -- Hoffstedt, Johan -- Naslund, Erik -- Britton, Tom -- Concha, Hernan -- Hassan, Moustapha -- Ryden, Mikael -- Frisen, Jonas -- Arner, Peter -- RR13461/RR/NCRR NIH HHS/ -- England -- Nature. 2008 Jun 5;453(7196):783-7. doi: 10.1038/nature06902.

    Description: Formation of catalytically active RNA structures within the spliceosome requires the assistance of proteins. However, little is known about the number and nature of proteins needed to establish and maintain the spliceosome's active site. Here we affinity-purified human spliceosomal C complexes and show that they catalyse exon ligation in the absence of added factors. Comparisons of the composition of the precatalytic versus the catalytic spliceosome revealed a marked exchange of proteins during the transition from the B to the C complex, with apparent stabilization of Prp19-CDC5 complex proteins and destabilization of SF3a/b proteins. Disruption of purified C complexes led to the isolation of a salt-stable ribonucleoprotein (RNP) core that contained both splicing intermediates and U2, U5 and U6 small nuclear RNA plus predominantly U5 and human Prp19-CDC5 proteins and Prp19-related factors. Our data provide insights into the spliceosome's catalytic RNP domain and indicate a central role for the aforementioned proteins in sustaining its catalytically active structure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bessonov, Sergey -- Anokhina, Maria -- Will, Cindy L -- Urlaub, Henning -- Luhrmann, Reinhard -- England -- Nature. 2008 Apr 17;452(7189):846-50. doi: 10.1038/nature06842.

    Description: Cohesin complexes mediate sister-chromatid cohesion in dividing cells but may also contribute to gene regulation in postmitotic cells. How cohesin regulates gene expression is not known. Here we describe cohesin-binding sites in the human genome and show that most of these are associated with the CCCTC-binding factor (CTCF), a zinc-finger protein required for transcriptional insulation. CTCF is dispensable for cohesin loading onto DNA, but is needed to enrich cohesin at specific binding sites. Cohesin enables CTCF to insulate promoters from distant enhancers and controls transcription at the H19/IGF2 (insulin-like growth factor 2) locus. This role of cohesin seems to be independent of its role in cohesion. We propose that cohesin functions as a transcriptional insulator, and speculate that subtle deficiencies in this function contribute to 'cohesinopathies' such as Cornelia de Lange syndrome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wendt, Kerstin S -- Yoshida, Keisuke -- Itoh, Takehiko -- Bando, Masashige -- Koch, Birgit -- Schirghuber, Erika -- Tsutsumi, Shuichi -- Nagae, Genta -- Ishihara, Ko -- Mishiro, Tsuyoshi -- Yahata, Kazuhide -- Imamoto, Fumio -- Aburatani, Hiroyuki -- Nakao, Mitsuyoshi -- Imamoto, Naoko -- Maeshima, Kazuhiro -- Shirahige, Katsuhiko -- Peters, Jan-Michael -- England -- Nature. 2008 Feb 14;451(7180):796-801. doi: 10.1038/nature06634.

    Description: Lancelets ('amphioxus') are the modern survivors of an ancient chordate lineage, with a fossil record dating back to the Cambrian period. Here we describe the structure and gene content of the highly polymorphic approximately 520-megabase genome of the Florida lancelet Branchiostoma floridae, and analyse it in the context of chordate evolution. Whole-genome comparisons illuminate the murky relationships among the three chordate groups (tunicates, lancelets and vertebrates), and allow not only reconstruction of the gene complement of the last common chordate ancestor but also partial reconstruction of its genomic organization, as well as a description of two genome-wide duplications and subsequent reorganizations in the vertebrate lineage. These genome-scale events shaped the vertebrate genome and provided additional genetic variation for exploitation during vertebrate evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Putnam, Nicholas H -- Butts, Thomas -- Ferrier, David E K -- Furlong, Rebecca F -- Hellsten, Uffe -- Kawashima, Takeshi -- Robinson-Rechavi, Marc -- Shoguchi, Eiichi -- Terry, Astrid -- Yu, Jr-Kai -- Benito-Gutierrez, E Lia -- Dubchak, Inna -- Garcia-Fernandez, Jordi -- Gibson-Brown, Jeremy J -- Grigoriev, Igor V -- Horton, Amy C -- de Jong, Pieter J -- Jurka, Jerzy -- Kapitonov, Vladimir V -- Kohara, Yuji -- Kuroki, Yoko -- Lindquist, Erika -- Lucas, Susan -- Osoegawa, Kazutoyo -- Pennacchio, Len A -- Salamov, Asaf A -- Satou, Yutaka -- Sauka-Spengler, Tatjana -- Schmutz, Jeremy -- Shin-I, Tadasu -- Toyoda, Atsushi -- Bronner-Fraser, Marianne -- Fujiyama, Asao -- Holland, Linda Z -- Holland, Peter W H -- Satoh, Nori -- Rokhsar, Daniel S -- BBS/B/12067/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBS/B/12067/2/Biotechnology and Biological Sciences Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2008 Jun 19;453(7198):1064-71. doi: 10.1038/nature06967.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Energy Joint Genome Institute, Walnut Creek, California 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18563158" target="_blank"〉PubMed〈/a〉

    Description: T helper (T(H)) cells constitute an important arm of the adaptive immune system because they coordinate defence against specific pathogens, and their unique cytokines and effector functions mediate different types of tissue inflammation. The recently discovered T(H)17 cells, the third subset of effector T helper cells, have been the subject of intense research aimed at understanding their role in immunity and disease. Here we review emerging data suggesting that T(H)17 cells have an important role in host defence against specific pathogens and are potent inducers of autoimmunity and tissue inflammation. In addition, the differentiation factors responsible for their generation have revealed an interesting reciprocal relationship with regulatory T (T(reg)) cells, which prevent tissue inflammation and mediate self-tolerance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bettelli, Estelle -- Korn, Thomas -- Oukka, Mohamed -- Kuchroo, Vijay K -- R01 AI073542/AI/NIAID NIH HHS/ -- R01 AI073542-01/AI/NIAID NIH HHS/ -- R01 AI073542-02/AI/NIAID NIH HHS/ -- R01 NS059996/NS/NINDS NIH HHS/ -- England -- Nature. 2008 Jun 19;453(7198):1051-7. doi: 10.1038/nature07036.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Neurologic Diseases, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18563156" target="_blank"〉PubMed〈/a〉

    Description: The RE1-silencing transcription factor (REST, also known as NRSF) is a master repressor of neuronal gene expression and neuronal programmes in non-neuronal lineages. Recently, REST was identified as a human tumour suppressor in epithelial tissues, suggesting that its regulation may have important physiological and pathological consequences. However, the pathways controlling REST have yet to be elucidated. Here we show that REST is regulated by ubiquitin-mediated proteolysis, and use an RNA interference (RNAi) screen to identify a Skp1-Cul1-F-box protein complex containing the F-box protein beta-TRCP (SCF(beta-TRCP)) as an E3 ubiquitin ligase responsible for REST degradation. beta-TRCP binds and ubiquitinates REST and controls its stability through a conserved phospho-degron. During neural differentiation, REST is degraded in a beta-TRCP-dependent manner. beta-TRCP is required for proper neural differentiation only in the presence of REST, indicating that beta-TRCP facilitates this process through degradation of REST. Conversely, failure to degrade REST attenuates differentiation. Furthermore, we find that beta-TRCP overexpression, which is common in human epithelial cancers, causes oncogenic transformation of human mammary epithelial cells and that this pathogenic function requires REST degradation. Thus, REST is a key target in beta-TRCP-driven transformation and the beta-TRCP-REST axis is a new regulatory pathway controlling neurogenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2688689/" 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/PMC2688689/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Westbrook, Thomas F -- Hu, Guang -- Ang, Xiaolu L -- Mulligan, Peter -- Pavlova, Natalya N -- Liang, Anthony -- Leng, Yumei -- Maehr, Rene -- Shi, Yang -- Harper, J Wade -- Elledge, Stephen J -- F31 NS054507-01/NS/NINDS NIH HHS/ -- R01 AG011085/AG/NIA NIH HHS/ -- R01 AG011085-16/AG/NIA NIH HHS/ -- R01 GM054137/GM/NIGMS NIH HHS/ -- R01 GM054137-13/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2008 Mar 20;452(7185):370-4. doi: 10.1038/nature06780.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Genetics, Harvard Partners Center for Genetics and Genomics, Harvard Medical School, 77 Avenue Louis Pasteur, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18354483" target="_blank"〉PubMed〈/a〉

    Description: Emerging infectious diseases (EIDs) are a significant burden on global economies and public health. Their emergence is thought to be driven largely by socio-economic, environmental and ecological factors, but no comparative study has explicitly analysed these linkages to understand global temporal and spatial patterns of EIDs. Here we analyse a database of 335 EID 'events' (origins of EIDs) between 1940 and 2004, and demonstrate non-random global patterns. EID events have risen significantly over time after controlling for reporting bias, with their peak incidence (in the 1980s) concomitant with the HIV pandemic. EID events are dominated by zoonoses (60.3% of EIDs): the majority of these (71.8%) originate in wildlife (for example, severe acute respiratory virus, Ebola virus), and are increasing significantly over time. We find that 54.3% of EID events are caused by bacteria or rickettsia, reflecting a large number of drug-resistant microbes in our database. Our results confirm that EID origins are significantly correlated with socio-economic, environmental and ecological factors, and provide a basis for identifying regions where new EIDs are most likely to originate (emerging disease 'hotspots'). They also reveal a substantial risk of wildlife zoonotic and vector-borne EIDs originating at lower latitudes where reporting effort is low. We conclude that global resources to counter disease emergence are poorly allocated, with the majority of the scientific and surveillance effort focused on countries from where the next important EID is least likely to originate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jones, Kate E -- Patel, Nikkita G -- Levy, Marc A -- Storeygard, Adam -- Balk, Deborah -- Gittleman, John L -- Daszak, Peter -- R01 AI079231/AI/NIAID NIH HHS/ -- R01 TW005869/TW/FIC NIH HHS/ -- T32 HD007338/HD/NICHD NIH HHS/ -- England -- Nature. 2008 Feb 21;451(7181):990-3. doi: 10.1038/nature06536.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Zoology, Zoological Society of London, Regents Park, London NW1 4RY, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18288193" target="_blank"〉PubMed〈/a〉

    Description: Human cancer cells typically harbour multiple chromosomal aberrations, nucleotide substitutions and epigenetic modifications that drive malignant transformation. The Cancer Genome Atlas (TCGA) pilot project aims to assess the value of large-scale multi-dimensional analysis of these molecular characteristics in human cancer and to provide the data rapidly to the research community. Here we report the interim integrative analysis of DNA copy number, gene expression and DNA methylation aberrations in 206 glioblastomas--the most common type of adult brain cancer--and nucleotide sequence aberrations in 91 of the 206 glioblastomas. This analysis provides new insights into the roles of ERBB2, NF1 and TP53, uncovers frequent mutations of the phosphatidylinositol-3-OH kinase regulatory subunit gene PIK3R1, and provides a network view of the pathways altered in the development of glioblastoma. Furthermore, integration of mutation, DNA methylation and clinical treatment data reveals a link between MGMT promoter methylation and a hypermutator phenotype consequent to mismatch repair deficiency in treated glioblastomas, an observation with potential clinical implications. Together, these findings establish the feasibility and power of TCGA, demonstrating that it can rapidly expand knowledge of the molecular basis of cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2671642/" 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/PMC2671642/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cancer Genome Atlas Research Network -- R01 CA099041/CA/NCI NIH HHS/ -- R01 CA099041-05/CA/NCI NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- U24 CA126543-01/CA/NCI NIH HHS/ -- U24 CA126544/CA/NCI NIH HHS/ -- U24 CA126544-01/CA/NCI NIH HHS/ -- U24 CA126546/CA/NCI NIH HHS/ -- U24 CA126546-01/CA/NCI NIH HHS/ -- U24 CA126551-01/CA/NCI NIH HHS/ -- U24 CA126554/CA/NCI NIH HHS/ -- U24 CA126554-01/CA/NCI NIH HHS/ -- U24 CA126561/CA/NCI NIH HHS/ -- U24 CA126561-01/CA/NCI NIH HHS/ -- U24 CA126563/CA/NCI NIH HHS/ -- U24 CA126563-01/CA/NCI NIH HHS/ -- U24CA126543/CA/NCI NIH HHS/ -- U24CA126544/CA/NCI NIH HHS/ -- U24CA126546/CA/NCI NIH HHS/ -- U24CA126551/CA/NCI NIH HHS/ -- U24CA126554/CA/NCI NIH HHS/ -- U24CA126561/CA/NCI NIH HHS/ -- U24CA126563/CA/NCI NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- U54 HG003067-01/HG/NHGRI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- U54 HG003079-05/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- U54 HG003273-01/HG/NHGRI NIH HHS/ -- U54HG003067/HG/NHGRI NIH HHS/ -- U54HG003079/HG/NHGRI NIH HHS/ -- U54HG003273/HG/NHGRI NIH HHS/ -- England -- Nature. 2008 Oct 23;455(7216):1061-8. doi: 10.1038/nature07385.

    Description: The association of genetic variation with disease and drug response, and improvements in nucleic acid technologies, have given great optimism for the impact of 'genomic medicine'. However, the formidable size of the diploid human genome, approximately 6 gigabases, has prevented the routine application of sequencing methods to deciphering complete individual human genomes. To realize the full potential of genomics for human health, this limitation must be overcome. Here we report the DNA sequence of a diploid genome of a single individual, James D. Watson, sequenced to 7.4-fold redundancy in two months using massively parallel sequencing in picolitre-size reaction vessels. This sequence was completed in two months at approximately one-hundredth of the cost of traditional capillary electrophoresis methods. Comparison of the sequence to the reference genome led to the identification of 3.3 million single nucleotide polymorphisms, of which 10,654 cause amino-acid substitution within the coding sequence. In addition, we accurately identified small-scale (2-40,000 base pair (bp)) insertion and deletion polymorphism as well as copy number variation resulting in the large-scale gain and loss of chromosomal segments ranging from 26,000 to 1.5 million base pairs. Overall, these results agree well with recent results of sequencing of a single individual by traditional methods. However, in addition to being faster and significantly less expensive, this sequencing technology avoids the arbitrary loss of genomic sequences inherent in random shotgun sequencing by bacterial cloning because it amplifies DNA in a cell-free system. As a result, we further demonstrate the acquisition of novel human sequence, including novel genes not previously identified by traditional genomic sequencing. This is the first genome sequenced by next-generation technologies. Therefore it is a pilot for the future challenges of 'personalized genome sequencing'.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wheeler, David A -- Srinivasan, Maithreyan -- Egholm, Michael -- Shen, Yufeng -- Chen, Lei -- McGuire, Amy -- He, Wen -- Chen, Yi-Ju -- Makhijani, Vinod -- Roth, G Thomas -- Gomes, Xavier -- Tartaro, Karrie -- Niazi, Faheem -- Turcotte, Cynthia L -- Irzyk, Gerard P -- Lupski, James R -- Chinault, Craig -- Song, Xing-zhi -- Liu, Yue -- Yuan, Ye -- Nazareth, Lynne -- Qin, Xiang -- Muzny, Donna M -- Margulies, Marcel -- Weinstock, George M -- Gibbs, Richard A -- Rothberg, Jonathan M -- U54 HG003273/HG/NHGRI NIH HHS/ -- England -- Nature. 2008 Apr 17;452(7189):872-6. doi: 10.1038/nature06884.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Genome Sequencing Center, Baylor College of Medicine, One Baylor Plaza, Houston, Texas 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18421352" target="_blank"〉PubMed〈/a〉

    Description: Human Argonaute (Ago) proteins are essential components of the RNA-induced silencing complexes (RISCs). Argonaute 2 (Ago2) has a P-element-induced wimpy testis (PIWI) domain, which folds like RNase H and is responsible for target RNA cleavage in RNA interference. Proteins such as Dicer, TRBP, MOV10, RHA, RCK/p54 and KIAA1093 associate with Ago proteins and participate in small RNA processing, RISC loading and localization of Ago proteins in the cytoplasmic messenger RNA processing bodies. However, mechanisms that regulate RNA interference remain obscure. Here we report physical interactions between Ago2 and the alpha-(P4H-alpha(I)) and beta-(P4H-beta) subunits of the type I collagen prolyl-4-hydroxylase (C-P4H(I)). Mass spectrometric analysis identified hydroxylation of the endogenous Ago2 at proline 700. In vitro, both Ago2 and Ago4 seem to be more efficiently hydroxylated than Ago1 and Ago3 by recombinant human C-P4H(I). Importantly, human cells depleted of P4H-alpha(I) or P4H-beta by short hairpin RNA and P4H-alpha(I) null mouse embryonic fibroblast cells showed reduced stability of Ago2 and impaired short interfering RNA programmed RISC activity. Furthermore, mutation of proline 700 to alanine also resulted in destabilization of Ago2, thus linking Ago2 P700 and hydroxylation at this residue to its stability regulation. These findings identify hydroxylation as a post-translational modification important for Ago2 stability and effective RNA interference.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2661850/" 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/PMC2661850/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Qi, Hank H -- Ongusaha, Pat P -- Myllyharju, Johanna -- Cheng, Dongmei -- Pakkanen, Outi -- Shi, Yujiang -- Lee, Sam W -- Peng, Junmin -- Shi, Yang -- AG025688/AG/NIA NIH HHS/ -- GM53874/GM/NIGMS NIH HHS/ -- R01 GM053874/GM/NIGMS NIH HHS/ -- R01 GM053874-15/GM/NIGMS NIH HHS/ -- England -- Nature. 2008 Sep 18;455(7211):421-4. doi: 10.1038/nature07186.

    Description: Typical 2-Cys peroxiredoxins (Prxs) have an important role in regulating hydrogen peroxide-mediated cell signalling. In this process, Prxs can become inactivated through the hyperoxidation of an active site Cys residue to Cys sulphinic acid. The unique repair of this moiety by sulphiredoxin (Srx) restores peroxidase activity and terminates the signal. The hyperoxidized form of Prx exists as a stable decameric structure with each active site buried. Therefore, it is unclear how Srx can access the sulphinic acid moiety. Here we present the 2.6 A crystal structure of the human Srx-PrxI complex. This complex reveals the complete unfolding of the carboxy terminus of Prx, and its unexpected packing onto the backside of Srx away from the Srx active site. Binding studies and activity analyses of site-directed mutants at this interface show that the interaction is required for repair to occur. Moreover, rearrangements in the Prx active site lead to a juxtaposition of the Prx Gly-Gly-Leu-Gly and Srx ATP-binding motifs, providing a structural basis for the first step of the catalytic mechanism. The results also suggest that the observed interactions may represent a common mode for other proteins to bind to Prxs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2646140/" 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/PMC2646140/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jonsson, Thomas J -- Johnson, Lynnette C -- Lowther, W Todd -- R01 GM072866/GM/NIGMS NIH HHS/ -- R01 GM072866-03/GM/NIGMS NIH HHS/ -- England -- Nature. 2008 Jan 3;451(7174):98-101. doi: 10.1038/nature06415.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Structural Biology and Department of Biochemistry, Wake Forest University School of Medicine, Medical Center Boulevard, Winston-Salem, North Carolina 27157, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18172504" target="_blank"〉PubMed〈/a〉

    Description: As arguably the simplest free-living animals, placozoans may represent a primitive metazoan form, yet their biology is poorly understood. Here we report the sequencing and analysis of the approximately 98 million base pair nuclear genome of the placozoan Trichoplax adhaerens. Whole-genome phylogenetic analysis suggests that placozoans belong to a 'eumetazoan' clade that includes cnidarians and bilaterians, with sponges as the earliest diverging animals. The compact genome shows conserved gene content, gene structure and synteny in relation to the human and other complex eumetazoan genomes. Despite the apparent cellular and organismal simplicity of Trichoplax, its genome encodes a rich array of transcription factor and signalling pathway genes that are typically associated with diverse cell types and developmental processes in eumetazoans, motivating further searches for cryptic cellular complexity and/or as yet unobserved life history stages.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Srivastava, Mansi -- Begovic, Emina -- Chapman, Jarrod -- Putnam, Nicholas H -- Hellsten, Uffe -- Kawashima, Takeshi -- Kuo, Alan -- Mitros, Therese -- Salamov, Asaf -- Carpenter, Meredith L -- Signorovitch, Ana Y -- Moreno, Maria A -- Kamm, Kai -- Grimwood, Jane -- Schmutz, Jeremy -- Shapiro, Harris -- Grigoriev, Igor V -- Buss, Leo W -- Schierwater, Bernd -- Dellaporta, Stephen L -- Rokhsar, Daniel S -- England -- Nature. 2008 Aug 21;454(7207):955-60. doi: 10.1038/nature07191.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Integrative Genomics and Department of Molecular and Cell Biology, University of California, Berkeley, California 94720, USA. msrivast@berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18719581" target="_blank"〉PubMed〈/a〉

    Description: Observations of individual virions in live cells have led to the characterization of their attachment, entry and intracellular transport. However, the assembly of individual virions has never been observed in real time. Insights into this process have come primarily from biochemical analyses of populations of virions or from microscopic studies of fixed infected cells. Thus, some assembly properties, such as kinetics and location, are either unknown or controversial. Here we describe quantitatively the genesis of individual virions in real time, from initiation of assembly to budding and release. We studied fluorescently tagged derivatives of Gag, the major structural component of HIV-1-which is sufficient to drive the assembly of virus-like particles-with the use of fluorescence resonance energy transfer, fluorescence recovery after photobleaching and total-internal-reflection fluorescent microscopy in living cells. Virions appeared individually at the plasma membrane, their assembly rate accelerated as Gag protein accumulated in cells, and typically 5-6 min was required to complete the assembly of a single virion. These approaches allow a previously unobserved view of the genesis of individual virions and the determination of parameters of viral assembly that are inaccessible with conventional techniques.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2708942/" 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/PMC2708942/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jouvenet, Nolwenn -- Bieniasz, Paul D -- Simon, Sanford M -- P20 GM072015/GM/NIGMS NIH HHS/ -- P20 GM072015-01/GM/NIGMS NIH HHS/ -- P20 GM072015-02/GM/NIGMS NIH HHS/ -- P20 GM072015-02S1/GM/NIGMS NIH HHS/ -- P20 GM072015-03/GM/NIGMS NIH HHS/ -- P20 GM072015-04/GM/NIGMS NIH HHS/ -- P20 GM072015-04S1/GM/NIGMS NIH HHS/ -- R01 AI089844/AI/NIAID NIH HHS/ -- R01 GM087977/GM/NIGMS NIH HHS/ -- England -- Nature. 2008 Jul 10;454(7201):236-40. doi: 10.1038/nature06998.

    Description: Neurotrophins (NTs) are important regulators for the survival, differentiation and maintenance of different peripheral and central neurons. NTs bind to two distinct classes of glycosylated receptor: the p75 neurotrophin receptor (p75(NTR)) and tyrosine kinase receptors (Trks). Whereas p75(NTR) binds to all NTs, the Trk subtypes are specific for each NT. The question of whether NTs stimulate p75(NTR) by inducing receptor homodimerization is still under debate. Here we report the 2.6-A resolution crystal structure of neurotrophin-3 (NT-3) complexed to the ectodomain of glycosylated p75(NTR). In contrast to the previously reported asymmetric complex structure, which contains a dimer of nerve growth factor (NGF) bound to a single ectodomain of deglycosylated p75(NTR) (ref. 3), we show that NT-3 forms a central homodimer around which two glycosylated p75(NTR) molecules bind symmetrically. Symmetrical binding occurs along the NT-3 interfaces, resulting in a 2:2 ligand-receptor cluster. A comparison of the symmetrical and asymmetric structures reveals significant differences in ligand-receptor interactions and p75(NTR) conformations. Biochemical experiments indicate that both NT-3 and NGF bind to p75(NTR) with 2:2 stoichiometry in solution, whereas the 2:1 complexes are the result of artificial deglycosylation. We therefore propose that the symmetrical 2:2 complex reflects a native state of p75(NTR) activation at the cell surface. These results provide a model for NTs-p75(NTR) recognition and signal generation, as well as insights into coordination between p75(NTR) and Trks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gong, Yong -- Cao, Peng -- Yu, Hong-jun -- Jiang, Tao -- England -- Nature. 2008 Aug 7;454(7205):789-93. doi: 10.1038/nature07089.

    Description: Despite their importance for urban planning, traffic forecasting and the spread of biological and mobile viruses, our understanding of the basic laws governing human motion remains limited owing to the lack of tools to monitor the time-resolved location of individuals. Here we study the trajectory of 100,000 anonymized mobile phone users whose position is tracked for a six-month period. We find that, in contrast with the random trajectories predicted by the prevailing Levy flight and random walk models, human trajectories show a high degree of temporal and spatial regularity, each individual being characterized by a time-independent characteristic travel distance and a significant probability to return to a few highly frequented locations. After correcting for differences in travel distances and the inherent anisotropy of each trajectory, the individual travel patterns collapse into a single spatial probability distribution, indicating that, despite the diversity of their travel history, humans follow simple reproducible patterns. This inherent similarity in travel patterns could impact all phenomena driven by human mobility, from epidemic prevention to emergency response, urban planning and agent-based modelling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gonzalez, Marta C -- Hidalgo, Cesar A -- Barabasi, Albert-Laszlo -- England -- Nature. 2008 Jun 5;453(7196):779-82. doi: 10.1038/nature06958.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Complex Network Research and Department of Physics, Biology and Computer Science, Northeastern University, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18528393" target="_blank"〉PubMed〈/a〉

    Description: Just-noticeable differences of physical parameters are often limited by the resolution of the peripheral sensory apparatus. Thus, two-point discrimination in vision is limited by the size of individual photoreceptors. Frequency selectivity is a basic property of neurons in the mammalian auditory pathway. However, just-noticeable differences of frequency are substantially smaller than the bandwidth of the peripheral sensors. Here we report that frequency tuning in single neurons recorded from human auditory cortex in response to random-chord stimuli is far narrower than that typically described in any other mammalian species (besides bats), and substantially exceeds that attributed to the human auditory periphery. Interestingly, simple spectral filter models failed to predict the neuronal responses to natural stimuli, including speech and music. Thus, natural sounds engage additional processing mechanisms beyond the exquisite frequency tuning probed by the random-chord stimuli.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2676858/" 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/PMC2676858/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bitterman, Y -- Mukamel, R -- Malach, R -- Fried, I -- Nelken, I -- R01 NS033221/NS/NINDS NIH HHS/ -- R01 NS033221-10/NS/NINDS NIH HHS/ -- England -- Nature. 2008 Jan 10;451(7175):197-201. doi: 10.1038/nature06476.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Life Science Institute, Hebrew University, Jerusalem 91904, Israel.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18185589" target="_blank"〉PubMed〈/a〉

    Description: Evolutionary novelties in the skeleton are usually expressed as changes in the timing of growth of features intrinsically integrated at different hierarchical levels of development. As a consequence, most of the shape-traits observed across species do vary quantitatively rather than qualitatively, in a multivariate space and in a modularized way. Because most phylogenetic analyses normally use discrete, hypothetically independent characters, previous attempts have disregarded the phylogenetic signals potentially enclosed in the shape of morphological structures. When analysing low taxonomic levels, where most variation is quantitative in nature, solving basic requirements like the choice of characters and the capacity of using continuous, integrated traits is of crucial importance in recovering wider phylogenetic information. This is particularly relevant when analysing extinct lineages, where available data are limited to fossilized structures. Here we show that when continuous, multivariant and modularized characters are treated as such, cladistic analysis successfully solves relationships among main Homo taxa. Our attempt is based on a combination of cladistics, evolutionary-development-derived selection of characters, and geometric morphometrics methods. In contrast with previous cladistic analyses of hominid phylogeny, our method accounts for the quantitative nature of the traits, and respects their morphological integration patterns. Because complex phenotypes are observable across different taxonomic groups and are potentially informative about phylogenetic relationships, future analyses should point strongly to the incorporation of these types of trait.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gonzalez-Jose, Rolando -- Escapa, Ignacio -- Neves, Walter A -- Cuneo, Ruben -- Pucciarelli, Hector M -- England -- Nature. 2008 Jun 5;453(7196):775-8. doi: 10.1038/nature06891.

    Description: The psychosis associated with schizophrenia is characterized by alterations in sensory processing and perception. Some antipsychotic drugs were identified by their high affinity for serotonin 5-HT2A receptors (2AR). Drugs that interact with metabotropic glutamate receptors (mGluR) also have potential for the treatment of schizophrenia. The effects of hallucinogenic drugs, such as psilocybin and lysergic acid diethylamide, require the 2AR and resemble some of the core symptoms of schizophrenia. Here we show that the mGluR2 interacts through specific transmembrane helix domains with the 2AR, a member of an unrelated G-protein-coupled receptor family, to form functional complexes in brain cortex. The 2AR-mGluR2 complex triggers unique cellular responses when targeted by hallucinogenic drugs, and activation of mGluR2 abolishes hallucinogen-specific signalling and behavioural responses. In post-mortem human brain from untreated schizophrenic subjects, the 2AR is upregulated and the mGluR2 is downregulated, a pattern that could predispose to psychosis. These regulatory changes indicate that the 2AR-mGluR2 complex may be involved in the altered cortical processes of schizophrenia, and this complex is therefore a promising new target for the treatment of psychosis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2743172/" 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/PMC2743172/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gonzalez-Maeso, Javier -- Ang, Rosalind L -- Yuen, Tony -- Chan, Pokman -- Weisstaub, Noelia V -- Lopez-Gimenez, Juan F -- Zhou, Mingming -- Okawa, Yuuya -- Callado, Luis F -- Milligan, Graeme -- Gingrich, Jay A -- Filizola, Marta -- Meana, J Javier -- Sealfon, Stuart C -- G9811527/Medical Research Council/United Kingdom -- P01 DA012923/DA/NIDA NIH HHS/ -- P01 DA012923-06A10004/DA/NIDA NIH HHS/ -- T32 DA007135/DA/NIDA NIH HHS/ -- T32 DA007135-25S1/DA/NIDA NIH HHS/ -- T32 GM062754/GM/NIGMS NIH HHS/ -- England -- Nature. 2008 Mar 6;452(7183):93-7. doi: 10.1038/nature06612.

    Description: The accumulation of misfolded proteins in intracellular amyloid inclusions, typical of many neurodegenerative disorders including Huntington's and prion disease, is thought to occur after failure of the cellular protein quality control mechanisms. Here we examine the formation of misfolded protein inclusions in the eukaryotic cytosol of yeast and mammalian cell culture models. We identify two intracellular compartments for the sequestration of misfolded cytosolic proteins. Partition of quality control substrates to either compartment seems to depend on their ubiquitination status and aggregation state. Soluble ubiquitinated misfolded proteins accumulate in a juxtanuclear compartment where proteasomes are concentrated. In contrast, terminally aggregated proteins are sequestered in a perivacuolar inclusion. Notably, disease-associated Huntingtin and prion proteins are preferentially directed to the perivacuolar compartment. Enhancing ubiquitination of a prion protein suffices to promote its delivery to the juxtanuclear inclusion. Our findings provide a framework for understanding the preferential accumulation of amyloidogenic proteins in inclusions linked to human disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2746971/" 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/PMC2746971/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaganovich, Daniel -- Kopito, Ron -- Frydman, Judith -- R01 GM056433/GM/NIGMS NIH HHS/ -- R01 GM056433-03/GM/NIGMS NIH HHS/ -- R01 GM056433-04/GM/NIGMS NIH HHS/ -- R01 GM056433-05/GM/NIGMS NIH HHS/ -- R01 GM056433-06/GM/NIGMS NIH HHS/ -- R01 GM056433-07/GM/NIGMS NIH HHS/ -- R01 GM056433-08/GM/NIGMS NIH HHS/ -- R01 NS042842/NS/NINDS NIH HHS/ -- R01 NS042842-07/NS/NINDS NIH HHS/ -- England -- Nature. 2008 Aug 28;454(7208):1088-95. doi: 10.1038/nature07195.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology and BioX Program, Stanford University, Stanford, California 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18756251" target="_blank"〉PubMed〈/a〉

    Description: Neuroscience has recently turned to the study of utilitarian and non-utilitarian moral judgement. Koenigs et al. examine the responses of normal subjects and those with ventromedial-prefrontal-cortex (VMPC) damage to moral scenarios drawn from functional magnetic resonance imaging studies by Greene et al., and claim that patients with VMPC damage have an abnormally "utilitarian" pattern of moral judgement. It is crucial to the claims of Koenigs et al. that the scenarios of Greene et al. pose a conflict between utilitarian consequence and duty: however, many of them do not meet this condition. Because of this methodological problem, it is too early to claim that VMPC patients have a utilitarian bias.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2922719/" 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/PMC2922719/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kahane, Guy -- Shackel, Nicholas -- P01 NS019632/NS/NINDS NIH HHS/ -- P01 NS019632-230003/NS/NINDS NIH HHS/ -- England -- Nature. 2008 Mar 20;452(7185):E5; author reply E5-6. doi: 10.1038/nature06785.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Oxford Uehiro Centre for Practical Ethics, University of Oxford, Oxford OX1 1PT, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18354427" target="_blank"〉PubMed〈/a〉
