    Description: Polo-like kinase-1 (PLK1) is an essential mitotic kinase regulating multiple aspects of the cell division process. Activation of PLK1 requires phosphorylation of a conserved threonine residue (Thr 210) in the T-loop of the PLK1 kinase domain, but the kinase responsible for this has not yet been affirmatively identified. Here we show that in human cells PLK1 activation occurs several hours before entry into mitosis, and requires aurora A (AURKA, also known as STK6)-dependent phosphorylation of Thr 210. We find that aurora A can directly phosphorylate PLK1 on Thr 210, and that activity of aurora A towards PLK1 is greatly enhanced by Bora (also known as C13orf34 and FLJ22624), a known cofactor for aurora A (ref. 7). We show that Bora/aurora-A-dependent phosphorylation is a prerequisite for PLK1 to promote mitotic entry after a checkpoint-dependent arrest. Importantly, expression of a PLK1-T210D phospho-mimicking mutant partially overcomes the requirement for aurora A in checkpoint recovery. Taken together, these data demonstrate that the initial activation of PLK1 is a primary function of aurora A.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Macurek, Libor -- Lindqvist, Arne -- Lim, Dan -- Lampson, Michael A -- Klompmaker, Rob -- Freire, Raimundo -- Clouin, Christophe -- Taylor, Stephen S -- Yaffe, Michael B -- Medema, Rene H -- CA112967/CA/NCI NIH HHS/ -- GM-60594/GM/NIGMS NIH HHS/ -- England -- Nature. 2008 Sep 4;455(7209):119-23. doi: 10.1038/nature07185.

    Description: With the recent recognition of non-coding RNAs (ncRNAs) flanking many genes, a central issue is to obtain a full understanding of their potential roles in regulated gene transcription programmes, possibly through different mechanisms. Here we show that an RNA-binding protein, TLS (for translocated in liposarcoma), serves as a key transcriptional regulatory sensor of DNA damage signals that, on the basis of its allosteric modulation by RNA, specifically binds to and inhibits CREB-binding protein (CBP) and p300 histone acetyltransferase activities on a repressed gene target, cyclin D1 (CCND1) in human cell lines. Recruitment of TLS to the CCND1 promoter to cause gene-specific repression is directed by single-stranded, low-copy-number ncRNA transcripts tethered to the 5' regulatory regions of CCND1 that are induced in response to DNA damage signals. Our data suggest that signal-induced ncRNAs localized to regulatory regions of transcription units can act cooperatively as selective ligands, recruiting and modulating the activities of distinct classes of RNA-binding co-regulators in response to specific signals, providing an unexpected ncRNA/RNA-binding protein-based strategy to integrate transcriptional programmes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2823488/" 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/PMC2823488/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Xiangting -- Arai, Shigeki -- Song, Xiaoyuan -- Reichart, Donna -- Du, Kun -- Pascual, Gabriel -- Tempst, Paul -- Rosenfeld, Michael G -- Glass, Christopher K -- Kurokawa, Riki -- CA097134/CA/NCI NIH HHS/ -- CA52599/CA/NCI NIH HHS/ -- DK074868/DK/NIDDK NIH HHS/ -- DK39949/DK/NIDDK NIH HHS/ -- HL59694/HL/NHLBI NIH HHS/ -- NS34934/NS/NINDS NIH HHS/ -- P30 CA08748/CA/NCI NIH HHS/ -- R01 CA052599/CA/NCI NIH HHS/ -- R01 CA052599-19/CA/NCI NIH HHS/ -- R01 DK091183/DK/NIDDK NIH HHS/ -- R01 HL059694/HL/NHLBI NIH HHS/ -- R01 HL059694-10/HL/NHLBI NIH HHS/ -- R01 NS034934/NS/NINDS NIH HHS/ -- R01 NS034934-20A1/NS/NINDS NIH HHS/ -- R37 DK039949/DK/NIDDK NIH HHS/ -- R37 DK039949-26/DK/NIDDK NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2008 Jul 3;454(7200):126-30. doi: 10.1038/nature06992.

    Description: The cellular innate immune system is essential for recognizing pathogen infection and for establishing effective host defence. But critical molecular determinants responsible for facilitating an appropriate immune response-following infection with DNA and RNA viruses, for example-remain to be identified. Here we report the identification, following expression cloning, of a molecule (STING; stimulator of interferon genes) that appears essential for effective innate immune signalling processes. It comprises five putative transmembrane regions, predominantly resides in the endoplasmic reticulum and is able to activate both NF-kappaB and IRF3 transcription pathways to induce expression of type I interferon (IFN-alpha and IFN-beta ) and exert a potent anti-viral state following expression. In contrast, loss of STING rendered murine embryonic fibroblasts extremely susceptible to negative-stranded virus infection, including vesicular stomatitis virus. Further, STING ablation abrogated the ability of intracellular B-form DNA, as well as members of the herpesvirus family, to induce IFN-beta, but did not significantly affect the Toll-like receptor (TLR) pathway. Yeast two-hybrid and co-immunoprecipitation studies indicated that STING interacts with RIG-I and with SSR2 (also known as TRAPbeta), which is a member of the translocon-associated protein (TRAP) complex required for protein translocation across the endoplasmic reticulum membrane following translation. Ablation by RNA interference of both TRAPbeta and translocon adaptor SEC61beta was subsequently found to inhibit STING's ability to stimulate expression of IFN-beta. Thus, as well as identifying a regulator of innate immune signalling, our results imply a potential role for the translocon in innate signalling pathways activated by select viruses as well as intracellular DNA.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2804933/" 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/PMC2804933/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ishikawa, Hiroki -- Barber, Glen N -- R01 AI079336/AI/NIAID NIH HHS/ -- R01 AI079336-01/AI/NIAID NIH HHS/ -- England -- Nature. 2008 Oct 2;455(7213):674-8. doi: 10.1038/nature07317.

    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: Genome stability requires one, and only one, DNA duplication at each S phase. The mechanisms preventing origin firing on newly replicated DNA are well documented, but much less is known about the mechanisms controlling the spacing of initiation events(2,3), namely the completion of DNA replication. Here we show that origin use in Chinese hamster cells depends on both the movement of the replication forks and the organization of chromatin loops. We found that slowing the replication speed triggers the recruitment of latent origins within minutes, allowing the completion of S phase in a timely fashion. When slowly replicating cells are shifted to conditions of fast fork progression, although the decrease in the overall number of active origins occurs within 2 h, the cells still have to go through a complete cell cycle before the efficiency specific to each origin is restored. We observed a strict correlation between replication speed during a given S phase and the size of chromatin loops in the next G1 phase. Furthermore, we found that origins located at or near sites of anchorage of chromatin loops in G1 are activated preferentially in the following S phase. These data suggest a mechanism of origin programming in which replication speed determines the spacing of anchorage regions of chromatin loops, that, in turn, controls the choice of initiation sites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Courbet, Sylvain -- Gay, Sophie -- Arnoult, Nausica -- Wronka, Gerd -- Anglana, Mauro -- Brison, Olivier -- Debatisse, Michelle -- England -- Nature. 2008 Sep 25;455(7212):557-60. doi: 10.1038/nature07233.

    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: Mathematical models predict that species interactions such as competition and predation can generate chaos. However, experimental demonstrations of chaos in ecology are scarce, and have been limited to simple laboratory systems with a short duration and artificial species combinations. Here, we present the first experimental demonstration of chaos in a long-term experiment with a complex food web. Our food web was isolated from the Baltic Sea, and consisted of bacteria, several phytoplankton species, herbivorous and predatory zooplankton species, and detritivores. The food web was cultured in a laboratory mesocosm, and sampled twice a week for more than 2,300 days. Despite constant external conditions, the species abundances showed striking fluctuations over several orders of magnitude. These fluctuations displayed a variety of different periodicities, which could be attributed to different species interactions in the food web. The population dynamics were characterized by positive Lyapunov exponents of similar magnitude for each species. Predictability was limited to a time horizon of 15-30 days, only slightly longer than the local weather forecast. Hence, our results demonstrate that species interactions in food webs can generate chaos. This implies that stability is not required for the persistence of complex food webs, and that the long-term prediction of species abundances can be fundamentally impossible.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beninca, Elisa -- Huisman, Jef -- Heerkloss, Reinhard -- Johnk, Klaus D -- Branco, Pedro -- Van Nes, Egbert H -- Scheffer, Marten -- Ellner, Stephen P -- England -- Nature. 2008 Feb 14;451(7180):822-5. doi: 10.1038/nature06512.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Aquatic Microbiology, Institute for Biodiversity and Ecosystem Dynamics, University of Amsterdam, Nieuwe Achtergracht 127, 1018 WS Amsterdam, The Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18273017" target="_blank"〉PubMed〈/a〉

    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: For a wide variety of microbial pathogens, the outcome of the infection is indeterminate. In some individuals the microbe is cleared, but in others it establishes a chronic infection, and the factors that tip this balance are often unknown. In a widely used model of chronic viral infection, C57BL/6 mice clear the Armstrong strain of lymphocytic choriomeningitis virus (LCMV), but the clone 13 strain persists. Here we show that the Armstrong strain induces a profound lymphopenia at days 1-3 after infection, but the clone 13 strain does not. If we transiently augment lymphopenia by treating the clone-13-infected mice with the drug FTY720 at days 0-2 after infection, the mice successfully clear the infection by day 30. Clearance does not occur when CD4 T cells are absent at the time of treatment, indicating that the drug is not exerting direct antiviral effects. Notably, FTY720 treatment of an already established persistent infection also leads to viral clearance. In both models, FTY720 treatment preserves or augments LCMV-specific CD4 and CD8 T-cell responses, a result that is counter-intuitive because FTY720 is generally regarded as a new immunosuppressive agent. Because FTY720 targets host pathways that are completely evolutionarily conserved, our results may be translatable into new immunotherapies for the treatment of chronic microbial infections in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Premenko-Lanier, Mary -- Moseley, Nelson B -- Pruett, Sarah T -- Romagnoli, Pablo A -- Altman, John D -- 5F32AI062002/AI/NIAID NIH HHS/ -- AI042373/AI/NIAID NIH HHS/ -- England -- Nature. 2008 Aug 14;454(7206):894-8. doi: 10.1038/nature07199.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Emory Vaccine Center and Department of Microbiology and Immunology, Yerkes National Primate Research Center and Emory University School of Medicine, 954 Gatewood Road, Atlanta, Georgia 30329, USA. mflanie@emory.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18704087" target="_blank"〉PubMed〈/a〉

    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: Contemporary phospholipid-based cell membranes are formidable barriers to the uptake of polar and charged molecules ranging from metal ions to complex nutrients. Modern cells therefore require sophisticated protein channels and pumps to mediate the exchange of molecules with their environment. The strong barrier function of membranes has made it difficult to understand the origin of cellular life and has been thought to preclude a heterotrophic lifestyle for primitive cells. Although nucleotides can cross dimyristoyl phosphatidylcholine membranes through defects formed at the gel-to-liquid transition temperature, phospholipid membranes lack the dynamic properties required for membrane growth. Fatty acids and their corresponding alcohols and glycerol monoesters are attractive candidates for the components of protocell membranes because they are simple amphiphiles that form bilayer membrane vesicles that retain encapsulated oligonucleotides and are capable of growth and division. Here we show that such membranes allow the passage of charged molecules such as nucleotides, so that activated nucleotides added to the outside of a model protocell spontaneously cross the membrane and take part in efficient template copying in the protocell interior. The permeability properties of prebiotically plausible membranes suggest that primitive protocells could have acquired complex nutrients from their environment in the absence of any macromolecular transport machinery; that is, they could have been obligate heterotrophs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2743009/" 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/PMC2743009/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mansy, Sheref S -- Schrum, Jason P -- Krishnamurthy, Mathangi -- Tobe, Sylvia -- Treco, Douglas A -- Szostak, Jack W -- F32 GM074506-01/GM/NIGMS NIH HHS/ -- F32 GM07450601/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2008 Jul 3;454(7200):122-5. doi: 10.1038/nature07018.

    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: We have followed individual ribosomes as they translate single messenger RNA hairpins tethered by the ends to optical tweezers. Here we reveal that translation occurs through successive translocation--and-pause cycles. The distribution of pause lengths, with a median of 2.8 s, indicates that at least two rate-determining processes control each pause. Each translocation step measures three bases--one codon-and occurs in less than 0.1 s. Analysis of the times required for translocation reveals, surprisingly, that there are three substeps in each step. Pause lengths, and thus the overall rate of translation, depend on the secondary structure of the mRNA; the applied force destabilizes secondary structure and decreases pause durations, but does not affect translocation times. Translocation and RNA unwinding are strictly coupled ribosomal functions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2556548/" 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/PMC2556548/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wen, Jin-Der -- Lancaster, Laura -- Hodges, Courtney -- Zeri, Ana-Carolina -- Yoshimura, Shige H -- Noller, Harry F -- Bustamante, Carlos -- Tinoco, Ignacio -- R01 GM010840/GM/NIGMS NIH HHS/ -- R01 GM010840-49/GM/NIGMS NIH HHS/ -- R01 GM010840-50/GM/NIGMS NIH HHS/ -- England -- Nature. 2008 Apr 3;452(7187):598-603. doi: 10.1038/nature06716.

    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: Type 1 diabetes (T1D) is a debilitating autoimmune disease that results from T-cell-mediated destruction of insulin-producing beta-cells. Its incidence has increased during the past several decades in developed countries, suggesting that changes in the environment (including the human microbial environment) may influence disease pathogenesis. The incidence of spontaneous T1D in non-obese diabetic (NOD) mice can be affected by the microbial environment in the animal housing facility or by exposure to microbial stimuli, such as injection with mycobacteria or various microbial products. Here we show that specific pathogen-free NOD mice lacking MyD88 protein (an adaptor for multiple innate immune receptors that recognize microbial stimuli) do not develop T1D. The effect is dependent on commensal microbes because germ-free MyD88-negative NOD mice develop robust diabetes, whereas colonization of these germ-free MyD88-negative NOD mice with a defined microbial consortium (representing bacterial phyla normally present in human gut) attenuates T1D. We also find that MyD88 deficiency changes the composition of the distal gut microbiota, and that exposure to the microbiota of specific pathogen-free MyD88-negative NOD donors attenuates T1D in germ-free NOD recipients. Together, these findings indicate that interaction of the intestinal microbes with the innate immune system is a critical epigenetic factor modifying T1D predisposition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2574766/" 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/PMC2574766/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wen, Li -- Ley, Ruth E -- Volchkov, Pavel Yu -- Stranges, Peter B -- Avanesyan, Lia -- Stonebraker, Austin C -- Hu, Changyun -- Wong, F Susan -- Szot, Gregory L -- Bluestone, Jeffrey A -- Gordon, Jeffrey I -- Chervonsky, Alexander V -- DK063452/DK/NIDDK NIH HHS/ -- DK30292/DK/NIDDK NIH HHS/ -- DK42086/DK/NIDDK NIH HHS/ -- DK45735/DK/NIDDK NIH HHS/ -- DK70977/DK/NIDDK NIH HHS/ -- P30 DK042086/DK/NIDDK NIH HHS/ -- P30 DK042086-16/DK/NIDDK NIH HHS/ -- P30 DK045735/DK/NIDDK NIH HHS/ -- P30 DK045735-10/DK/NIDDK NIH HHS/ -- P30 DK045735-119006/DK/NIDDK NIH HHS/ -- P30 DK056341/DK/NIDDK NIH HHS/ -- P30 DK056341-07/DK/NIDDK NIH HHS/ -- P30 DK056341-08/DK/NIDDK NIH HHS/ -- P30 DK063720/DK/NIDDK NIH HHS/ -- P30 DK063720-01/DK/NIDDK NIH HHS/ -- P30 DK63720/DK/NIDDK NIH HHS/ -- R01 DK030292/DK/NIDDK NIH HHS/ -- R01 DK030292-24/DK/NIDDK NIH HHS/ -- R01 DK070977/DK/NIDDK NIH HHS/ -- R01 DK070977-04/DK/NIDDK NIH HHS/ -- R21 DK063452/DK/NIDDK NIH HHS/ -- R21 DK063452-02/DK/NIDDK NIH HHS/ -- R37 AI046643/AI/NIAID NIH HHS/ -- R37 AI046643-10/AI/NIAID NIH HHS/ -- R37 AI46643/AI/NIAID NIH HHS/ -- England -- Nature. 2008 Oct 23;455(7216):1109-13. doi: 10.1038/nature07336.

    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: The vertebrate body axis is subdivided into repeated segments, best exemplified by the vertebrae that derive from embryonic somites. The number of somites is precisely defined for any given species but varies widely from one species to another. To determine the mechanism controlling somite number, we have compared somitogenesis in zebrafish, chicken, mouse and corn snake embryos. Here we present evidence that in all of these species a similar 'clock-and-wavefront' mechanism operates to control somitogenesis; in all of them, somitogenesis is brought to an end through a process in which the presomitic mesoderm, having first increased in size, gradually shrinks until it is exhausted, terminating somite formation. In snake embryos, however, the segmentation clock rate is much faster relative to developmental rate than in other amniotes, leading to a greatly increased number of smaller-sized somites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gomez, Celine -- Ozbudak, Ertugrul M -- Wunderlich, Joshua -- Baumann, Diana -- Lewis, Julian -- Pourquie, Olivier -- Cancer Research UK/United Kingdom -- Howard Hughes Medical Institute/ -- England -- Nature. 2008 Jul 17;454(7202):335-9. doi: 10.1038/nature07020.
