    Beschreibung: During mouse embryogenesis, reversion of imprinted X chromosome inactivation in the pluripotent inner cell mass of the female blastocyst is initiated by the repression of Xist from the paternal X chromosome. Here we report that key factors supporting pluripotency-Nanog, Oct3/4, and Sox2-bind within Xist intron 1 in undifferentiated embryonic stem (ES) cells. Whereas Nanog null ES cells display a reversible and moderate up-regulation of Xist in the absence of any apparent modification of Oct3/4 and Sox2 binding, the drastic release of all three factors from Xist intron 1 triggers rapid ectopic accumulation of Xist RNA. We conclude that the three main genetic factors underlying pluripotency cooperate to repress Xist and thus couple X inactivation reprogramming to the control of pluripotency during embryogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Navarro, Pablo -- Chambers, Ian -- Karwacki-Neisius, Violetta -- Chureau, Corinne -- Morey, Celine -- Rougeulle, Claire -- Avner, Philip -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2008 Sep 19;321(5896):1693-5. doi: 10.1126/science.1160952.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut Pasteur, Unite de Genetique Moleculaire Murine, CNRS, URA2578, F-75015, Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18802003" target="_blank"〉PubMed〈/a〉

    Beschreibung: The hippocampus is an area of the brain involved in learning and memory. It contains parallel excitatory pathways referred to as the trisynaptic pathway (which carries information as follows: entorhinal cortex --〉 dentate gyrus --〉 CA3 --〉 CA1 --〉 entorhinal cortex) and the monosynaptic pathway (entorhinal cortex --〉 CA1 --〉 entorhinal cortex). We developed a generally applicable tetanus toxin-based method for transgenic mice that permits inducible and reversible inhibition of synaptic transmission and applied it to the trisynaptic pathway while preserving transmission in the monosynaptic pathway. We found that synaptic output from CA3 in the trisynaptic pathway is dispensable and the short monosynaptic pathway is sufficient for incremental spatial learning. In contrast, the full trisynaptic pathway containing CA3 is required for rapid one-trial contextual learning, for pattern completion-based memory recall, and for spatial tuning of CA1 cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakashiba, Toshiaki -- Young, Jennie Z -- McHugh, Thomas J -- Buhl, Derek L -- Tonegawa, Susumu -- P50-MH58880/MH/NIMH NIH HHS/ -- R01-MH078821/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2008 Feb 29;319(5867):1260-4. doi: 10.1126/science.1151120.

    Beschreibung: The transition from naive to activated T cells is marked by alternative splicing of pre-mRNA encoding the transmembrane phosphatase CD45. Using a short hairpin RNA interference screen, we identified heterogeneous ribonucleoprotein L-like (hnRNPLL) as a critical inducible regulator of CD45 alternative splicing. HnRNPLL was up-regulated in stimulated T cells, bound CD45 transcripts, and was both necessary and sufficient for CD45 alternative splicing. Depletion or overexpression of hnRNPLL in B and T cell lines and primary T cells resulted in reciprocal alteration of CD45RA and RO expression. Exon array analysis suggested that hnRNPLL acts as a global regulator of alternative splicing in activated T cells. Induction of hnRNPLL during hematopoietic cell activation and differentiation may allow cells to rapidly shift their transcriptomes to favor proliferation and inhibit cell death.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2791692/" 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/PMC2791692/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Oberdoerffer, Shalini -- Moita, Luis Ferreira -- Neems, Daniel -- Freitas, Rui P -- Hacohen, Nir -- Rao, Anjana -- AI40127/AI/NIAID NIH HHS/ -- AI44432/AI/NIAID NIH HHS/ -- CA42471/CA/NCI NIH HHS/ -- R01 AI040127/AI/NIAID NIH HHS/ -- R01 AI040127-18/AI/NIAID NIH HHS/ -- R01 AI040127-19/AI/NIAID NIH HHS/ -- R01 AI044432/AI/NIAID NIH HHS/ -- R01 AI044432-09/AI/NIAID NIH HHS/ -- R01 AI044432-10/AI/NIAID NIH HHS/ -- R01 AI080875/AI/NIAID NIH HHS/ -- R01 AI080875-01/AI/NIAID NIH HHS/ -- R01 CA042471/CA/NCI NIH HHS/ -- R01 CA042471-23/CA/NCI NIH HHS/ -- R21 AI071060/AI/NIAID NIH HHS/ -- R21 AI071060-01/AI/NIAID NIH HHS/ -- R21 AI071060-02/AI/NIAID NIH HHS/ -- T32 HL066987/HL/NHLBI NIH HHS/ -- U19 AI070352/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2008 Aug 1;321(5889):686-91. doi: 10.1126/science.1157610.

    Beschreibung: Retinoic acid (RA) is an essential extrinsic inducer of meiotic initiation in mammalian germ cells. However, RA acts too widely in mammalian development to account, by itself, for the cell-type and temporal specificity of meiotic initiation. We considered parallels to yeast, in which extrinsic and intrinsic factors combine to restrict meiotic initiation. We demonstrate that, in mouse embryos, extrinsic and intrinsic factors together regulate meiotic initiation. The mouse RNA-binding protein DAZL, which is expressed by postmigratory germ cells, is a key intrinsic factor, enabling those cells to initiate meiosis in response to RA. Within a brief developmental window, Dazl-expressing germ cells in both XX and XY embryos actively acquire the ability to interpret RA as a meiosis-inducing signal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Yanfeng -- Gill, Mark E -- Koubova, Jana -- Page, David C -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Dec 12;322(5908):1685-7. doi: 10.1126/science.1166340.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Whitehead Institute, and Department of Biology, Massachusetts Institute of Technology, 9 Cambridge Center, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19074348" target="_blank"〉PubMed〈/a〉

    Beschreibung: In mammals, dosage compensation is achieved by X-chromosome inactivation (XCI) in the female. The noncoding Xist gene initiates silencing of the X chromosome, whereas its antisense partner Tsix blocks silencing. The complementarity of Xist and Tsix RNAs has long suggested a role for RNA interference (RNAi). Here, we report that murine Xist and Tsix form duplexes in vivo. During XCI, the duplexes are processed to small RNAs (sRNAs), most likely on the active X (Xa) in a Dicer-dependent manner. Deleting Dicer compromises sRNA production and derepresses Xist. Furthermore, without Dicer, Xist RNA cannot accumulate and histone 3 lysine 27 trimethylation is blocked on the inactive X (Xi). The defects are partially rescued by truncating Tsix. Thus, XCI and RNAi intersect, down-regulating Xist on Xa and spreading silencing on Xi.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2584363/" 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/PMC2584363/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ogawa, Yuya -- Sun, Bryan K -- Lee, Jeannie T -- R01 GM058839/GM/NIGMS NIH HHS/ -- R01 GM058839-10/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Jun 6;320(5881):1336-41. doi: 10.1126/science.1157676.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Massachusetts General Hospital and Howard Hughes Medical Institute, Boston, MA 02114, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18535243" target="_blank"〉PubMed〈/a〉

    Beschreibung: The mapping of numbers onto space is fundamental to measurement and to mathematics. Is this mapping a cultural invention or a universal intuition shared by all humans regardless of culture and education? We probed number-space mappings in the Mundurucu, an Amazonian indigene group with a reduced numerical lexicon and little or no formal education. At all ages, the Mundurucu mapped symbolic and nonsymbolic numbers onto a logarithmic scale, whereas Western adults used linear mapping with small or symbolic numbers and logarithmic mapping when numbers were presented nonsymbolically under conditions that discouraged counting. This indicates that the mapping of numbers onto space is a universal intuition and that this initial intuition of number is logarithmic. The concept of a linear number line appears to be a cultural invention that fails to develop in the absence of formal education.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2610411/" 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/PMC2610411/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dehaene, Stanislas -- Izard, Veronique -- Spelke, Elizabeth -- Pica, Pierre -- New York, N.Y. -- Science. 2008 May 30;320(5880):1217-20. doi: 10.1126/science.1156540.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM, Cognitive Neuro-imaging Unit, Institut Federatif de Recherche (IFR) 49, Gif sur Yvette, France. stanislas.dehaene@cea.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18511690" target="_blank"〉PubMed〈/a〉

    Beschreibung: Membrane and secretory proteins cotranslationally enter and are folded in the endoplasmic reticulum (ER). Misfolded or unassembled proteins are discarded by a process known as ER-associated degradation (ERAD), which involves their retrotranslocation into the cytosol. ERAD substrates frequently contain disulfide bonds that must be cleaved before their retrotranslocation. Here, we found that an ER-resident protein ERdj5 had a reductase activity, cleaved the disulfide bonds of misfolded proteins, and accelerated ERAD through its physical and functional associations with EDEM (ER degradation-enhancing alpha-mannosidase-like protein) and an ER-resident chaperone BiP. Thus, ERdj5 is a member of a supramolecular ERAD complex that recognizes and unfolds misfolded proteins for their efficient retrotranslocation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ushioda, Ryo -- Hoseki, Jun -- Araki, Kazutaka -- Jansen, Gregor -- Thomas, David Y -- Nagata, Kazuhiro -- New York, N.Y. -- Science. 2008 Jul 25;321(5888):569-72. doi: 10.1126/science.1159293.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Biology, Institute for Frontier Medical Sciences, Kyoto University, Kyoto 606-8397, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18653895" target="_blank"〉PubMed〈/a〉

    Beschreibung: After disappointing results from all efficacy trials conducted to date, the field of microbicides research now faces substantial challenges. Poor coordination among interested parties and the choice of nonvalidated scientific targets for phase III studies have hampered progress and created mistrust about the use of microbicides as a method to prevent HIV-1 sexual transmission. Although new promising strategies are available, there will need to be serious reappraisals of how decisions are made to advance the next generations of candidates into clinical trials, and the use of appropriate animal models in this process will be critical.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2835691/" 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/PMC2835691/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grant, Robert M -- Hamer, Dean -- Hope, Thomas -- Johnston, Rowena -- Lange, Joep -- Lederman, Michael M -- Lieberman, Judy -- Miller, Christopher J -- Moore, John P -- Mosier, Donald E -- Richman, Douglas D -- Schooley, Robert T -- Springer, Marty S -- Veazey, Ronald S -- Wainberg, Mark A -- U19 AI076981/AI/NIAID NIH HHS/ -- U19 AI076981-01/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2008 Jul 25;321(5888):532-4. doi: 10.1126/science.1160355.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉J.

    Beschreibung: Understanding cell morphogenesis during metazoan development requires knowledge of how cells and the extracellular matrix produce and respond to forces. We investigated how apoptosis, which remodels tissue by eliminating supernumerary cells, also contributes forces to a tissue (the amnioserosa) that promotes cell-sheet fusion (dorsal closure) in the Drosophila embryo. We showed that expression in the amnioserosa of proteins that suppress or enhance apoptosis slows or speeds dorsal closure, respectively. These changes correlate with the forces produced by the amnioserosa and the rate of seam formation between the cell sheets (zipping), key processes that contribute to closure. This apoptotic force is used by the embryo to drive cell-sheet movements during development, a role not classically attributed to apoptosis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2757114/" 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/PMC2757114/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Toyama, Yusuke -- Peralta, Xomalin G -- Wells, Adrienne R -- Kiehart, Daniel P -- Edwards, Glenn S -- GM33830/GM/NIGMS NIH HHS/ -- R01 GM033830/GM/NIGMS NIH HHS/ -- R01 GM033830-24/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2008 Sep 19;321(5896):1683-6. doi: 10.1126/science.1157052.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Physics Department and Free Electron Laser Laboratory, Duke University, Durham, NC 27708, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18802000" target="_blank"〉PubMed〈/a〉

    Beschreibung: Intraluminal vesicles of multivesicular endosomes are either sorted for cargo degradation into lysosomes or secreted as exosomes into the extracellular milieu. The mechanisms underlying the sorting of membrane into the different populations of intraluminal vesicles are unknown. Here, we find that cargo is segregated into distinct subdomains on the endosomal membrane and that the transfer of exosome-associated domains into the lumen of the endosome did not depend on the function of the ESCRT (endosomal sorting complex required for transport) machinery, but required the sphingolipid ceramide. Purified exosomes were enriched in ceramide, and the release of exosomes was reduced after the inhibition of neutral sphingomyelinases. These results establish a pathway in intraendosomal membrane transport and exosome formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Trajkovic, Katarina -- Hsu, Chieh -- Chiantia, Salvatore -- Rajendran, Lawrence -- Wenzel, Dirk -- Wieland, Felix -- Schwille, Petra -- Brugger, Britta -- Simons, Mikael -- New York, N.Y. -- Science. 2008 Feb 29;319(5867):1244-7. doi: 10.1126/science.1153124.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Biochemistry and Molecular Cell Biology, University of Gottingen, 37073 Gottingen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18309083" target="_blank"〉PubMed〈/a〉

    Beschreibung: Current theories hypothesize that dopamine neuronal firing encodes reward prediction errors. Although studies in nonhuman species provide direct support for this theory, functional magnetic resonance imaging (fMRI) studies in humans have focused on brain areas targeted by dopamine neurons [ventral striatum (VStr)] rather than on brainstem dopaminergic nuclei [ventral tegmental area (VTA) and substantia nigra]. We used fMRI tailored to directly image the brainstem. When primary rewards were used in an experiment, the VTA blood oxygen level-dependent (BOLD) response reflected a positive reward prediction error, whereas the VStr encoded positive and negative reward prediction errors. When monetary gains and losses were used, VTA BOLD responses reflected positive reward prediction errors modulated by the probability of winning. We detected no significant VTA BOLD response to nonrewarding events.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉D'Ardenne, Kimberlee -- McClure, Samuel M -- Nystrom, Leigh E -- Cohen, Jonathan D -- F32 MH072141/MH/NIMH NIH HHS/ -- P50 MH062196/MH/NIMH NIH HHS/ -- T32 MH065214/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2008 Feb 29;319(5867):1264-7. doi: 10.1126/science.1150605.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Princeton University, Princeton, NJ 08544, USA. dardenne@princeton.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18309087" target="_blank"〉PubMed〈/a〉

    Beschreibung: Nuclear reprogramming describes a switch in gene expression of one kind of cell to that of another unrelated cell type. Early studies in frog cloning provided some of the first experimental evidence for reprogramming. Subsequent procedures included mammalian somatic cell nuclear transfer, cell fusion, induction of pluripotency by ectopic gene expression, and direct reprogramming. Through these methods it becomes possible to derive one kind of specialized cell (such as a brain cell) from another, more accessible, tissue (such as skin) in the same individual. This has potential applications for cell replacement without the immunosuppression treatments that are required when cells are transferred between genetically different individuals. This article provides some background to this field, a discussion of mechanisms and efficiency, and comments on prospects for future nuclear reprogramming research.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gurdon, J B -- Melton, D A -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2008 Dec 19;322(5909):1811-5. doi: 10.1126/science.1160810.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust/Cancer Research UK Gurdon Institute and Department of Zoology, University of Cambridge, Cambridge CB2 12N, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19095934" target="_blank"〉PubMed〈/a〉

    Beschreibung: The repeated discovery of adult dinosaurs in close association with egg clutches leads to speculation over the type and extent of care exhibited by these extinct animals for their eggs and young. To assess parental care in Cretaceous troodontid and oviraptorid dinosaurs, we examined clutch volume and the bone histology of brooding adults. In comparison to four archosaur care regressions, the relatively large clutch volumes of Troodon, Oviraptor, and Citipati scale most closely with a bird-paternal care model. Clutch-associated adults lack the maternal and reproductively associated histologic features common to extant archosaurs. Large clutch volumes and a suite of reproductive features shared only with birds favor paternal care, possibly within a polygamous mating system. Paternal care in both troodontids and oviraptorids indicates that this care system evolved before the emergence of birds and represents birds' ancestral condition. In extant birds and over most adult sizes, paternal and biparental care correspond to the largest and smallest relative clutch volumes, respectively.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Varricchio, David J -- Moore, Jason R -- Erickson, Gregory M -- Norell, Mark A -- Jackson, Frankie D -- Borkowski, John J -- New York, N.Y. -- Science. 2008 Dec 19;322(5909):1826-8. doi: 10.1126/science.1163245.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, Montana State University, Bozeman, MT 59717, USA. djv@montana.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19095938" target="_blank"〉PubMed〈/a〉

    Beschreibung: Cytidine deaminases of the APOBEC3 family all have specificity for single-stranded DNA, which may become exposed during replication or transcription of double-stranded DNA. Three human APOBEC3A (hA3A), hA3B, and hA3H genes are expressed in keratinocytes and skin, leading us to determine whether genetic editing of human papillomavirus (HPV) DNA occurred. In a study of HPV1a plantar warts and HPV16 precancerous cervical biopsies, hyperedited HPV1a and HPV16 genomes were found. Strictly analogous results were obtained from transfection experiments with HPV plasmid DNA and the three nuclear localized enzymes: hA3A, hA3C, and hA3H. Thus, stochastic or transient overexpression of APOBEC3 genes may expose the genome to a broad spectrum of mutations that could influence the development of tumors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vartanian, Jean-Pierre -- Guetard, Denise -- Henry, Michel -- Wain-Hobson, Simon -- New York, N.Y. -- Science. 2008 Apr 11;320(5873):230-3. doi: 10.1126/science.1153201.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Retrovirology Unit, Institut Pasteur, 28 Rue de Docteur Roux, 75724 Paris cedex 15, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18403710" target="_blank"〉PubMed〈/a〉

    Beschreibung: Glioblastoma multiforme (GBM) is the most common and lethal type of brain cancer. To identify the genetic alterations in GBMs, we sequenced 20,661 protein coding genes, determined the presence of amplifications and deletions using high-density oligonucleotide arrays, and performed gene expression analyses using next-generation sequencing technologies in 22 human tumor samples. This comprehensive analysis led to the discovery of a variety of genes that were not known to be altered in GBMs. Most notably, we found recurrent mutations in the active site of isocitrate dehydrogenase 1 (IDH1) in 12% of GBM patients. Mutations in IDH1 occurred in a large fraction of young patients and in most patients with secondary GBMs and were associated with an increase in overall survival. These studies demonstrate the value of unbiased genomic analyses in the characterization of human brain cancer and identify a potentially useful genetic alteration for the classification and targeted therapy of GBMs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2820389/" 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/PMC2820389/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parsons, D Williams -- Jones, Sian -- Zhang, Xiaosong -- Lin, Jimmy Cheng-Ho -- Leary, Rebecca J -- Angenendt, Philipp -- Mankoo, Parminder -- Carter, Hannah -- Siu, I-Mei -- Gallia, Gary L -- Olivi, Alessandro -- McLendon, Roger -- Rasheed, B Ahmed -- Keir, Stephen -- Nikolskaya, Tatiana -- Nikolsky, Yuri -- Busam, Dana A -- Tekleab, Hanna -- Diaz, Luis A Jr -- Hartigan, James -- Smith, Doug R -- Strausberg, Robert L -- Marie, Suely Kazue Nagahashi -- Shinjo, Sueli Mieko Oba -- Yan, Hai -- Riggins, Gregory J -- Bigner, Darell D -- Karchin, Rachel -- Papadopoulos, Nick -- Parmigiani, Giovanni -- Vogelstein, Bert -- Velculescu, Victor E -- Kinzler, Kenneth W -- 5P50-NS-20023/NS/NINDS NIH HHS/ -- CA09547/CA/NCI NIH HHS/ -- CA108786/CA/NCI NIH HHS/ -- CA11898/CA/NCI NIH HHS/ -- CA121113/CA/NCI NIH HHS/ -- CA43460/CA/NCI NIH HHS/ -- CA57345/CA/NCI NIH HHS/ -- CA62924/CA/NCI NIH HHS/ -- NS052507/NS/NINDS NIH HHS/ -- P50 CA062924/CA/NCI NIH HHS/ -- P50 CA062924-160017/CA/NCI NIH HHS/ -- R01 CA121113/CA/NCI NIH HHS/ -- R01 CA121113-04/CA/NCI NIH HHS/ -- R01 CA140316/CA/NCI NIH HHS/ -- R37 CA043460/CA/NCI NIH HHS/ -- R37 CA043460-27/CA/NCI NIH HHS/ -- R37 CA057345/CA/NCI NIH HHS/ -- R37 CA057345-13/CA/NCI NIH HHS/ -- R37 CA057345-17/CA/NCI NIH HHS/ -- R37 CA057345-18/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Sep 26;321(5897):1807-12. doi: 10.1126/science.1164382.

    Beschreibung: MyD88 is a key downstream adapter for most Toll-like receptors (TLRs) and interleukin-1 receptors (IL-1Rs). MyD88 deficiency in mice leads to susceptibility to a broad range of pathogens in experimental settings of infection. We describe a distinct situation in a natural setting of human infection. Nine children with autosomal recessive MyD88 deficiency suffered from life-threatening, often recurrent pyogenic bacterial infections, including invasive pneumococcal disease. However, these patients were otherwise healthy, with normal resistance to other microbes. Their clinical status improved with age, but not due to any cellular leakiness in MyD88 deficiency. The MyD88-dependent TLRs and IL-1Rs are therefore essential for protective immunity to a small number of pyogenic bacteria, but redundant for host defense to most natural infections.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2688396/" 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/PMC2688396/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉von Bernuth, Horst -- Picard, Capucine -- Jin, Zhongbo -- Pankla, Rungnapa -- Xiao, Hui -- Ku, Cheng-Lung -- Chrabieh, Maya -- Mustapha, Imen Ben -- Ghandil, Pegah -- Camcioglu, Yildiz -- Vasconcelos, Julia -- Sirvent, Nicolas -- Guedes, Margarida -- Vitor, Artur Bonito -- Herrero-Mata, Maria Jose -- Arostegui, Juan Ignacio -- Rodrigo, Carlos -- Alsina, Laia -- Ruiz-Ortiz, Estibaliz -- Juan, Manel -- Fortuny, Claudia -- Yague, Jordi -- Anton, Jordi -- Pascal, Mariona -- Chang, Huey-Hsuan -- Janniere, Lucile -- Rose, Yoann -- Garty, Ben-Zion -- Chapel, Helen -- Issekutz, Andrew -- Marodi, Laszlo -- Rodriguez-Gallego, Carlos -- Banchereau, Jacques -- Abel, Laurent -- Li, Xiaoxia -- Chaussabel, Damien -- Puel, Anne -- Casanova, Jean-Laurent -- U19 AI057234/AI/NIAID NIH HHS/ -- U19 AI057234-02/AI/NIAID NIH HHS/ -- U19 AIO57234-02/PHS HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Aug 1;321(5889):691-6. doi: 10.1126/science.1158298.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Genetics of Infectious Diseases, INSERM U550, Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18669862" target="_blank"〉PubMed〈/a〉

    Beschreibung: To sustain or repair cooperation during a social exchange, adaptive creatures must understand social gestures and the consequences when shared expectations about fair exchange are violated by accident or intent. We recruited 55 individuals afflicted with borderline personality disorder (BPD) to play a multiround economic exchange game with healthy partners. Behaviorally, individuals with BPD showed a profound incapacity to maintain cooperation, and were impaired in their ability to repair broken cooperation on the basis of a quantitative measure of coaxing. Neurally, activity in the anterior insula, a region known to respond to norm violations across affective, interoceptive, economic, and social dimensions, strongly differentiated healthy participants from individuals with BPD. Healthy subjects showed a strong linear relation between anterior insula response and both magnitude of monetary offer received from their partner (input) and the amount of money repaid to their partner (output). In stark contrast, activity in the anterior insula of BPD participants was related only to the magnitude of repayment sent back to their partner (output), not to the magnitude of offers received (input). These neural and behavioral data suggest that norms used in perception of social gestures are pathologically perturbed or missing altogether among individuals with BPD. This game-theoretic approach to psychopathology may open doors to new ways of characterizing and studying a range of mental illnesses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4105006/" 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/PMC4105006/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉King-Casas, Brooks -- Sharp, Carla -- Lomax-Bream, Laura -- Lohrenz, Terry -- Fonagy, Peter -- Montague, P Read -- DA11723/DA/NIDA NIH HHS/ -- F32 MH078485/MH/NIMH NIH HHS/ -- MH078485/MH/NIMH NIH HHS/ -- MH52797/MH/NIMH NIH HHS/ -- NS045790/NS/NINDS NIH HHS/ -- R01 DA011723/DA/NIDA NIH HHS/ -- R01 MH052797/MH/NIMH NIH HHS/ -- R01 NS045790/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2008 Aug 8;321(5890):806-10. doi: 10.1126/science.1156902.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Computational Psychiatry Unit and Department of Neuroscience, Baylor College of Medicine, 1 Baylor Plaza, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18687957" target="_blank"〉PubMed〈/a〉

    Beschreibung: Golgins, long stringlike proteins, tether cisternae and transport vesicles at the Golgi apparatus. We examined the attachment of golgin GMAP-210 to lipid membranes. GMAP-210 connected highly curved liposomes to flatter ones. This asymmetric tethering relied on motifs that sensed membrane curvature both in the N terminus of GMAP-210 and in ArfGAP1, which controlled the interaction of the C terminus of GMAP-210 with the small guanine nucleotide-binding protein Arf1. Because membrane curvature constantly changes during vesicular trafficking, this mode of tethering suggests a way to maintain the Golgi architecture without compromising membrane flow.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drin, Guillaume -- Morello, Vincent -- Casella, Jean-Francois -- Gounon, Pierre -- Antonny, Bruno -- New York, N.Y. -- Science. 2008 May 2;320(5876):670-3. doi: 10.1126/science.1155821.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Pharmacologie Moleculaire et Cellulaire, Universite de Nice Sophia Antipolis and CNRS, 660 route des lucioles, 06560 Valbonne, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18451304" target="_blank"〉PubMed〈/a〉

    Beschreibung: The canonical Wnt-beta-catenin signaling pathway is initiated by inducing phosphorylation of one of the Wnt receptors, low-density lipoprotein receptor-related protein 6 (LRP6), at threonine residue 1479 (Thr1479) and serine residue 1490 (Ser1490). By screening a human kinase small interfering RNA library, we identified phosphatidylinositol 4-kinase type II alpha and phosphatidylinositol-4-phosphate 5-kinase type I (PIP5KI) as required for Wnt3a-induced LRP6 phosphorylation at Ser1490 in mammalian cells and confirmed that these kinases are important for Wnt signaling in Xenopus embryos. Wnt3a stimulates the formation of phosphatidylinositol 4,5-bisphosphates [PtdIns (4,5)P2] through frizzled and dishevelled, the latter of which directly interacted with and activated PIP5KI. In turn, PtdIns (4,5)P2 regulated phosphorylation of LRP6 at Thr1479 and Ser1490. Therefore, our study reveals a signaling mechanism for Wnt to regulate LRP6 phosphorylation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2532521/" 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/PMC2532521/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pan, Weijun -- Choi, Sun-Cheol -- Wang, He -- Qin, Yuanbo -- Volpicelli-Daley, Laura -- Swan, Laura -- Lucast, Louise -- Khoo, Cynthia -- Zhang, Xiaowu -- Li, Lin -- Abrams, Charles S -- Sokol, Sergei Y -- Wu, Dianqing -- AR051476/AR/NIAMS NIH HHS/ -- CA132317/CA/NCI NIH HHS/ -- DA018343/DA/NIDA NIH HHS/ -- HL080706/HL/NHLBI NIH HHS/ -- NS36251/NS/NINDS NIH HHS/ -- P30 DA018343/DA/NIDA NIH HHS/ -- R01 AR051476/AR/NIAMS NIH HHS/ -- R01 AR051476-01A1/AR/NIAMS NIH HHS/ -- R01 AR051476-02/AR/NIAMS NIH HHS/ -- R01 AR051476-03/AR/NIAMS NIH HHS/ -- R01 CA132317/CA/NCI NIH HHS/ -- R01 CA132317-01A2/CA/NCI NIH HHS/ -- R01 CA139395/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2008 Sep 5;321(5894):1350-3. doi: 10.1126/science.1160741.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Yale University School of Medicine, New Haven, CT 06510, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18772438" target="_blank"〉PubMed〈/a〉

    Beschreibung: The mammalian vomeronasal organ detects complex chemical signals that convey information about gender, strain, and the social and reproductive status of an individual. How these signals are encoded is poorly understood. We developed transgenic mice expressing the calcium indicator G-CaMP2 and analyzed population responses of vomeronasal neurons to urine from individual animals. A substantial portion of cells was activated by either male or female urine, but only a small population of cells responded exclusively to gender-specific cues shared across strains and individuals. Female cues activated more cells and were subject to more complex hormonal regulations than male cues. In contrast to gender, strain and individual information was encoded by the combinatorial activation of neurons such that urine from different individuals activated distinctive cell populations.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2602951/" 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/PMC2602951/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉He, Jie -- Ma, Limei -- Kim, Sangseong -- Nakai, Junichi -- Yu, C Ron -- NIDCD 008003/PHS HHS/ -- R01 DC008003/DC/NIDCD NIH HHS/ -- R01 DC008003-03/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 2008 Apr 25;320(5875):535-8. doi: 10.1126/science.1154476.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Stowers Institute for Medical Research, 1000 East 50th Street, Kansas City, MO 64110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18436787" target="_blank"〉PubMed〈/a〉

    Beschreibung: Purines are synthesized de novo in 10 chemical steps that are catalyzed by six enzymes in eukaryotes. Studies in vitro have provided little evidence of anticipated protein-protein interactions that would enable substrate channeling and regulation of the metabolic flux. We applied fluorescence microscopy to HeLa cells and discovered that all six enzymes colocalize to form clusters in the cellular cytoplasm. The association and dissociation of these enzyme clusters can be regulated dynamically, by either changing the purine levels of or adding exogenous agents to the culture media. Collectively, the data provide strong evidence for the formation of a multi-enzyme complex, the "purinosome," to carry out de novo purine biosynthesis in cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉An, Songon -- Kumar, Ravindra -- Sheets, Erin D -- Benkovic, Stephen J -- R21 AG030949/AG/NIA NIH HHS/ -- R21 AG030949-01/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2008 Apr 4;320(5872):103-6. doi: 10.1126/science.1152241.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Pennsylvania State University, University Park, PA 16802, USA. sua13@psu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18388293" target="_blank"〉PubMed〈/a〉

    Beschreibung: Transcription in mammalian cells can be assessed at a genome-wide level, but it has been difficult to reliably determine whether individual transcripts are derived from the plus or minus strands of chromosomes. This distinction can be critical for understanding the relationship between known transcripts (sense) and the complementary antisense transcripts that may regulate them. Here, we describe a technique that can be used to (i) identify the DNA strand of origin for any particular RNA transcript, and (ii) quantify the number of sense and antisense transcripts from expressed genes at a global level. We examined five different human cell types and in each case found evidence for antisense transcripts in 2900 to 6400 human genes. The distribution of antisense transcripts was distinct from that of sense transcripts, was nonrandom across the genome, and differed among cell types. Antisense transcripts thus appear to be a pervasive feature of human cells, which suggests that they are a fundamental component of gene regulation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2824178/" 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/PMC2824178/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉He, Yiping -- Vogelstein, Bert -- Velculescu, Victor E -- Papadopoulos, Nickolas -- Kinzler, Kenneth W -- CA121113/CA/NCI NIH HHS/ -- CA43460/CA/NCI NIH HHS/ -- CA57345/CA/NCI NIH HHS/ -- CA62924/CA/NCI NIH HHS/ -- R37 CA057345/CA/NCI NIH HHS/ -- R37 CA057345-17/CA/NCI NIH HHS/ -- R37 CA057345-18/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2008 Dec 19;322(5909):1855-7. doi: 10.1126/science.1163853.

    Beschreibung: Schizophrenia is a devastating neurodevelopmental disorder whose genetic influences remain elusive. We hypothesize that individually rare structural variants contribute to the illness. Microdeletions and microduplications 〉100 kilobases were identified by microarray comparative genomic hybridization of genomic DNA from 150 individuals with schizophrenia and 268 ancestry-matched controls. All variants were validated by high-resolution platforms. Novel deletions and duplications of genes were present in 5% of controls versus 15% of cases and 20% of young-onset cases, both highly significant differences. The association was independently replicated in patients with childhood-onset schizophrenia as compared with their parents. Mutations in cases disrupted genes disproportionately from signaling networks controlling neurodevelopment, including neuregulin and glutamate pathways. These results suggest that multiple, individually rare mutations altering genes in neurodevelopmental pathways contribute to schizophrenia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walsh, Tom -- McClellan, Jon M -- McCarthy, Shane E -- Addington, Anjene M -- Pierce, Sarah B -- Cooper, Greg M -- Nord, Alex S -- Kusenda, Mary -- Malhotra, Dheeraj -- Bhandari, Abhishek -- Stray, Sunday M -- Rippey, Caitlin F -- Roccanova, Patricia -- Makarov, Vlad -- Lakshmi, B -- Findling, Robert L -- Sikich, Linmarie -- Stromberg, Thomas -- Merriman, Barry -- Gogtay, Nitin -- Butler, Philip -- Eckstrand, Kristen -- Noory, Laila -- Gochman, Peter -- Long, Robert -- Chen, Zugen -- Davis, Sean -- Baker, Carl -- Eichler, Evan E -- Meltzer, Paul S -- Nelson, Stanley F -- Singleton, Andrew B -- Lee, Ming K -- Rapoport, Judith L -- King, Mary-Claire -- Sebat, Jonathan -- HD043569/HD/NICHD NIH HHS/ -- M01 RR000046/RR/NCRR NIH HHS/ -- MH061355/MH/NIMH NIH HHS/ -- MH061464/MH/NIMH NIH HHS/ -- MH061528/MH/NIMH NIH HHS/ -- NS052108/NS/NINDS NIH HHS/ -- R01 HD043569/HD/NICHD NIH HHS/ -- RR000046/RR/NCRR NIH HHS/ -- RR025014/RR/NCRR NIH HHS/ -- U01 MH061355/MH/NIMH NIH HHS/ -- U01 MH061464/MH/NIMH NIH HHS/ -- U01 MH061528/MH/NIMH NIH HHS/ -- U24 NS052108/NS/NINDS NIH HHS/ -- UL1 RR025014/RR/NCRR NIH HHS/ -- Howard Hughes Medical Institute/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2008 Apr 25;320(5875):539-43. doi: 10.1126/science.1155174.

    Beschreibung: Sleep is an essential process conserved from flies to humans. The importance of sleep is underscored by its tight homeostatic control. Through a forward genetic screen, we identified a gene, sleepless, required for sleep in Drosophila. The sleepless gene encodes a brain-enriched, glycosylphosphatidylinositol-anchored protein. Loss of SLEEPLESS protein caused an extreme (〉80%) reduction in sleep; a moderate reduction in SLEEPLESS had minimal effects on baseline sleep but markedly reduced the amount of recovery sleep after sleep deprivation. Genetic and molecular analyses revealed that quiver, a mutation that impairs Shaker-dependent potassium current, is an allele of sleepless.

We propose that SLEEPLESS is a signaling molecule that connects sleep drive to lowered membrane excitability.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2771549/" 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/PMC2771549/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koh, Kyunghee -- Joiner, William J -- Wu, Mark N -- Yue, Zhifeng -- Smith, Corinne J -- Sehgal, Amita -- AG017628/AG/NIA NIH HHS/ -- P01 AG017628/AG/NIA NIH HHS/ -- P01 AG017628-070004/AG/NIA NIH HHS/ -- R01 NS072431/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Jul 18;321(5887):372-6. doi: 10.1126/science.1155942.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Neuroscience, University of Pennsylvania, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18635795" target="_blank"〉PubMed〈/a〉

    Beschreibung: Amyotrophic lateral sclerosis (ALS) is a fatal motor neuron disorder characterized pathologically by ubiquitinated TAR DNA binding protein (TDP-43) inclusions. The function of TDP-43 in the nervous system is uncertain, and a mechanistic role in neurodegeneration remains speculative. We identified neighboring mutations in a highly conserved region of TARDBP in sporadic and familial ALS cases. TARDBPM337V segregated with disease within one kindred and a genome-wide scan confirmed that linkage was restricted to chromosome 1p36, which contains the TARDBP locus. Mutant forms of TDP-43 fragmented in vitro more readily than wild type and, in vivo, caused neural apoptosis and developmental delay in the chick embryo. Our evidence suggests a pathophysiological link between TDP-43 and ALS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sreedharan, Jemeen -- Blair, Ian P -- Tripathi, Vineeta B -- Hu, Xun -- Vance, Caroline -- Rogelj, Boris -- Ackerley, Steven -- Durnall, Jennifer C -- Williams, Kelly L -- Buratti, Emanuele -- Baralle, Francisco -- de Belleroche, Jacqueline -- Mitchell, J Douglas -- Leigh, P Nigel -- Al-Chalabi, Ammar -- Miller, Christopher C -- Nicholson, Garth -- Shaw, Christopher E -- G0500289/Medical Research Council/United Kingdom -- G0501573/Medical Research Council/United Kingdom -- G0600974/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2008 Mar 21;319(5870):1668-72. doi: 10.1126/science.1154584.

    Beschreibung: "Warmth" is the most powerful personality trait in social judgment, and attachment theorists have stressed the importance of warm physical contact with caregivers during infancy for healthy relationships in adulthood. Intriguingly, recent research in humans points to the involvement of the insula in the processing of both physical temperature and interpersonal warmth (trust) information. Accordingly, we hypothesized that experiences of physical warmth (or coldness) would increase feelings of interpersonal warmth (or coldness), without the person's awareness of this influence. In study 1, participants who briefly held a cup of hot (versus iced) coffee judged a target person as having a "warmer" personality (generous, caring); in study 2, participants holding a hot (versus cold) therapeutic pad were more likely to choose a gift for a friend instead of for themselves.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2737341/" 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/PMC2737341/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, Lawrence E -- Bargh, John A -- MH-R01-60767/MH/NIMH NIH HHS/ -- R01 MH060767-09/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2008 Oct 24;322(5901):606-7. doi: 10.1126/science.1162548.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Leeds School of Business, University of Colorado at Boulder, UCB 419, Boulder, CO, 80309-0419, USA. lawrence.williams@colorado.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18948544" target="_blank"〉PubMed〈/a〉

    Beschreibung: Pluripotent stem cells have been generated from mouse and human somatic cells by viral expression of the transcription factors Oct4, Sox2, Klf4, and c-Myc. A major limitation of this technology is the use of potentially harmful genome-integrating viruses. We generated mouse induced pluripotent stem (iPS) cells from fibroblasts and liver cells by using nonintegrating adenoviruses transiently expressing Oct4, Sox2, Klf4, and c-Myc. These adenoviral iPS (adeno-iPS) cells show DNA demethylation characteristic of reprogrammed cells, express endogenous pluripotency genes, form teratomas, and contribute to multiple tissues, including the germ line, in chimeric mice. Our results provide strong evidence that insertional mutagenesis is not required for in vitro reprogramming. Adenoviral reprogramming may provide an improved method for generating and studying patient-specific stem cells and for comparing embryonic stem cells and iPS cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3987909/" 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/PMC3987909/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stadtfeld, Matthias -- Nagaya, Masaki -- Utikal, Jochen -- Weir, Gordon -- Hochedlinger, Konrad -- DP2 OD003266/OD/NIH HHS/ -- New York, N.Y. -- Science. 2008 Nov 7;322(5903):945-9. doi: 10.1126/science.1162494.

    Beschreibung: Previous studies have reported that related human couples tend to produce more children than unrelated couples but have been unable to determine whether this difference is biological or stems from socioeconomic variables. Our results, drawn from all known couples of the Icelandic population born between 1800 and 1965, show a significant positive association between kinship and fertility, with the greatest reproductive success observed for couples related at the level of third and fourth cousins. Owing to the relative socioeconomic homogeneity of Icelanders, and the observation of highly significant differences in the fertility of couples separated by very fine intervals of kinship, we conclude that this association is likely to have a biological basis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Helgason, Agnar -- Palsson, Saebjorn -- Gudbjartsson, Daniel F -- Kristjansson, Thornordur -- Stefansson, Kari -- New York, N.Y. -- Science. 2008 Feb 8;319(5864):813-6. doi: 10.1126/science.1150232.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉deCODE Genetics, Sturlugata 8, 101 Reykjavik, Iceland. agnar@decode.is〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18258915" target="_blank"〉PubMed〈/a〉

    Beschreibung: Naturally occurring Foxp3+CD4+ regulatory T cells (Tregs) are essential for maintaining immunological self-tolerance and immune homeostasis. Here, we show that a specific deficiency of cytotoxic T lymphocyte antigen 4 (CTLA-4) in Tregs results in spontaneous development of systemic lymphoproliferation, fatal T cell-mediated autoimmune disease, and hyperproduction of immunoglobulin E in mice, and it also produces potent tumor immunity. Treg-specific CTLA-4 deficiency impairs in vivo and in vitro suppressive function of Tregs-in particular, Treg-mediated down-regulation of CD80 and CD86 expression on dendritic cells. Thus, natural Tregs may critically require CTLA-4 to suppress immune responses by affecting the potency of antigen-presenting cells to activate other T cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wing, Kajsa -- Onishi, Yasushi -- Prieto-Martin, Paz -- Yamaguchi, Tomoyuki -- Miyara, Makoto -- Fehervari, Zoltan -- Nomura, Takashi -- Sakaguchi, Shimon -- New York, N.Y. -- Science. 2008 Oct 10;322(5899):271-5. doi: 10.1126/science.1160062.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Experimental Pathology, Institute for Frontier Medical Sciences, Kyoto University, Kyoto 606-8507, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18845758" target="_blank"〉PubMed〈/a〉

    Beschreibung: The control of innate immune responses through activation of the nuclear transcription factor NF-kappaB is essential for the elimination of invading microbial pathogens. We showed that the bacterial N-(3-oxo-dodecanoyl) homoserine lactone (C12) selectively impairs the regulation of NF-kappaB functions in activated mammalian cells. The consequence is specific repression of stimulus-mediated induction of NF-kappaB-responsive genes encoding inflammatory cytokines and other immune regulators. These findings uncover a strategy by which C12-producing opportunistic pathogens, such as Pseudomonas aeruginosa, attenuate the innate immune system to establish and maintain local persistent infection in humans, for example, in cystic fibrosis patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kravchenko, Vladimir V -- Kaufmann, Gunnar F -- Mathison, John C -- Scott, David A -- Katz, Alexander Z -- Grauer, David C -- Lehmann, Mandy -- Meijler, Michael M -- Janda, Kim D -- Ulevitch, Richard J -- New York, N.Y. -- Science. 2008 Jul 11;321(5886):259-63. doi: 10.1126/science.1156499.

    Beschreibung: The majority of mitochondrial DNA (mtDNA) mutations that cause human disease are mild to moderately deleterious, yet many random mtDNA mutations would be expected to be severe. To determine the fate of the more severe mtDNA mutations, we introduced mtDNAs containing two mutations that affect oxidative phosphorylation into the female mouse germ line. The severe ND6 mutation was selectively eliminated during oogenesis within four generations, whereas the milder COI mutation was retained throughout multiple generations even though the offspring consistently developed mitochondrial myopathy and cardiomyopathy. Thus, severe mtDNA mutations appear to be selectively eliminated from the female germ line, thereby minimizing their impact on population fitness.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3049809/" 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/PMC3049809/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fan, Weiwei -- Waymire, Katrina G -- Narula, Navneet -- Li, Peng -- Rocher, Christophe -- Coskun, Pinar E -- Vannan, Mani A -- Narula, Jagat -- Macgregor, Grant R -- Wallace, Douglas C -- AG13154/AG/NIA NIH HHS/ -- AG16573/AG/NIA NIH HHS/ -- AG24373/AG/NIA NIH HHS/ -- DK73691/DK/NIDDK NIH HHS/ -- HD45913/HD/NICHD NIH HHS/ -- NS21328/NS/NINDS NIH HHS/ -- U01 HD045913-01/HD/NICHD NIH HHS/ -- U01 HD045913-02/HD/NICHD NIH HHS/ -- U01 HD045913-03/HD/NICHD NIH HHS/ -- U01 HD045913-04/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2008 Feb 15;319(5865):958-62. doi: 10.1126/science.1147786.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Molecular and Mitochondrial Medicine and Genetics, University of California, Irvine, CA 92697, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18276892" target="_blank"〉PubMed〈/a〉

    Beschreibung: Adenovirus small early region 1a (e1a) protein drives cells into S phase by binding RB family proteins and the closely related histone acetyl transferases p300 and CBP. The interaction with RB proteins displaces them from DNA-bound E2F transcription factors, reversing their repression of cell cycle genes. However, it has been unclear how the e1a interaction with p300 and CBP promotes passage through the cell cycle. We show that this interaction causes a threefold reduction in total cellular histone H3 lysine 18 acetylation (H3K18ac). CBP and p300 are required for acetylation at this site because their knockdown causes specific hypoacetylation at H3K18. SV40 T antigen also induces H3K18 hypoacetylation. Because global hypoacetylation at this site is observed in prostate carcinomas with poor prognosis, this suggests that processes resulting in global H3K18 hypoacetylation may be linked to oncogenic transformation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2756290/" 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/PMC2756290/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Horwitz, Gregory A -- Zhang, Kangling -- McBrian, Matthew A -- Grunstein, Michael -- Kurdistani, Siavash K -- Berk, Arnold J -- CA25235/CA/NCI NIH HHS/ -- R37 CA025235/CA/NCI NIH HHS/ -- R37 CA025235-30/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2008 Aug 22;321(5892):1084-5. doi: 10.1126/science.1155544.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Biology Institute, University of California, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18719283" target="_blank"〉PubMed〈/a〉

    Beschreibung: Hepatic glucose production is critical for basal brain function and survival when dietary glucose is unavailable. Glucose-6-phosphatase (G6Pase) is an essential, rate-limiting enzyme that serves as a terminal gatekeeper for hepatic glucose release into the plasma. Mutations in G6Pase result in Von Gierke's disease (glycogen storage disease-1a), a potentially fatal genetic disorder. We have identified the transcriptional coactivator SRC-2 as a regulator of fasting hepatic glucose release, a function that SRC-2 performs by controlling the expression of hepatic G6Pase. SRC-2 modulates G6Pase expression directly by acting as a coactivator with the orphan nuclear receptor RORalpha. In addition, SRC-2 ablation, in both a whole-body and liver-specific manner, resulted in a Von Gierke's disease phenotype in mice. Our results position SRC-2 as a critical regulator of mammalian glucose production.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2668604/" 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/PMC2668604/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chopra, Atul R -- Louet, Jean-Francois -- Saha, Pradip -- An, Jie -- Demayo, Franco -- Xu, Jianming -- York, Brian -- Karpen, Saul -- Finegold, Milton -- Moore, David -- Chan, Lawrence -- Newgard, Christopher B -- O'Malley, Bert W -- DK58242/DK/NIDDK NIH HHS/ -- HL51586/HL/NHLBI NIH HHS/ -- P01 DK059820/DK/NIDDK NIH HHS/ -- P01 DK059820-08/DK/NIDDK NIH HHS/ -- P01 DK58398/DK/NIDDK NIH HHS/ -- P01 DK59820/DK/NIDDK NIH HHS/ -- R01 DK056239/DK/NIDDK NIH HHS/ -- R01 DK056239-08/DK/NIDDK NIH HHS/ -- U19 DK062434/DK/NIDDK NIH HHS/ -- U19 DK062434-07/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2008 Nov 28;322(5906):1395-9. doi: 10.1126/science.1164847.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Biology, Baylor College of Medicine, 1 Baylor Plaza, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19039140" target="_blank"〉PubMed〈/a〉

    Beschreibung: High copy number and random segregation confound genetic analysis of the mitochondrial genome. We developed an efficient selection for heritable mitochondrial genome (mtDNA) mutations in Drosophila, thereby enhancing a metazoan model for study of mitochondrial genetics and mutations causing human mitochondrial disease. Targeting a restriction enzyme to mitochondria in the germline compromised fertility, but escaper progeny carried homoplasmic mtDNA mutations lacking the cleavage site. Among mutations eliminating a site in the cytochrome c oxidase gene, mt:CoI(A302T) was healthy, mt:CoI(R301L) was male sterile but otherwise healthy, and mt:CoI(R301S) exhibited a wide range of defects, including growth retardation, neurodegeneration, muscular atrophy, male sterility, and reduced life span. Thus, germline expression of mitochondrial restriction enzymes creates a powerful selection and has allowed direct isolation of mitochondrial mutants in a metazoan.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2754248/" 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/PMC2754248/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xu, Hong -- DeLuca, Steven Z -- O'Farrell, Patrick H -- R01 AI060102/AI/NIAID NIH HHS/ -- R01 AI060102-08/AI/NIAID NIH HHS/ -- R01 GM037193/GM/NIGMS NIH HHS/ -- R01 GM037193-22/GM/NIGMS NIH HHS/ -- R01 GM086854/GM/NIGMS NIH HHS/ -- R01 GM086854-09A1/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2008 Jul 25;321(5888):575-7. doi: 10.1126/science.1160226.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Biophysics, University of California at San Francisco, San Francisco, CA 94158-2200, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18653897" target="_blank"〉PubMed〈/a〉

    Beschreibung: The ability to select a better option from multiple acceptable ones is important for animals to optimize their resources. The mechanisms that underlie such decision-making processes are not well understood. We found that selection of egg-laying site in Drosophila melanogaster is a suitable system to probe the neural circuit that governs simple decision-making processes. First, Drosophila females pursue active probing of the environment before depositing each egg, apparently to evaluate site quality for every egg. Second, Drosophila females can either accept or reject a sucrose-containing medium, depending on the context. Last, communication of the "acceptability" of the sucrose-containing medium as an egg-laying option to the reproductive system depends on the function of a group of insulin-like peptide 7 (ILP7)-producing neurons. These findings suggest that selection of egg-laying site involves a simple decision-making process and provide an entry point toward a systematic dissection of this process.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2581776/" 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/PMC2581776/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yang, Chung-Hui -- Belawat, Priyanka -- Hafen, Ernst -- Jan, Lily Y -- Jan, Yuh-Nung -- R01 MH084234/MH/NIMH NIH HHS/ -- R01 NS040929/NS/NINDS NIH HHS/ -- R01 NS040929-08/NS/NINDS NIH HHS/ -- R01 NS047200-04/NS/NINDS NIH HHS/ -- R01 NS40929/NS/NINDS NIH HHS/ -- R37 NS040929/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Mar 21;319(5870):1679-83. doi: 10.1126/science.1151842.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Physiology, Biochemistry, and Biophysics, University of California at San Francisco, San Francisco, CA 94143-0725, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18356529" target="_blank"〉PubMed〈/a〉

    Beschreibung: Our ability to remember what we have seen is very limited. Most current views characterize this limit as a fixed number of items-only four objects-that can be held in visual working memory. We show that visual memory capacity is not fixed by the number of objects, but rather is a limited resource that is shared out dynamically between all items in the visual scene. This resource can be shifted flexibly between objects, with allocation biased by selective attention and toward targets of upcoming eye movements. The proportion of resources allocated to each item determines the precision with which it is remembered, a relation that we show is governed by a simple power law, allowing quantitative estimates of resource distribution in a scene.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2532743/" 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/PMC2532743/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bays, Paul M -- Husain, Masud -- 061140/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2008 Aug 8;321(5890):851-4. doi: 10.1126/science.1158023.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Cognitive Neuroscience, University College London, 17 Queen Square, London WC1N 3AR, UK. p.bays@ion.ucl.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18687968" target="_blank"〉PubMed〈/a〉

    Beschreibung: Close relatedness has long been considered crucial to the evolution of eusociality. However, it has recently been suggested that close relatedness may be a consequence, rather than a cause, of eusociality. We tested this idea with a comparative analysis of female mating frequencies in 267 species of eusocial bees, wasps, and ants. We found that mating with a single male, which maximizes relatedness, is ancestral for all eight independent eusocial lineages that we investigated. Mating with multiple males is always derived. Furthermore, we found that high polyandry (〉2 effective mates) occurs only in lineages whose workers have lost reproductive totipotency. These results provide the first evidence that monogamy was critical in the evolution of eusociality, strongly supporting the prediction of inclusive fitness theory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hughes, William O H -- Oldroyd, Benjamin P -- Beekman, Madeleine -- Ratnieks, Francis L W -- New York, N.Y. -- Science. 2008 May 30;320(5880):1213-6. doi: 10.1126/science.1156108.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Integrative and Comparative Biology, University of Leeds, Leeds, LS2 9JT, UK. w.o.h.hughes@leeds.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18511689" target="_blank"〉PubMed〈/a〉

    Beschreibung: As obligate intracellular parasites, viruses expertly modify cellular processes to facilitate their replication and spread, often by encoding genes that mimic the functions of cellular proteins while lacking regulatory features that modify their activity. We show that the human cytomegalovirus UL97 protein has activities similar to cellular cyclin-cyclin-dependent kinase (CDK) complexes. UL97 phosphorylated and inactivated the retinoblastoma tumor suppressor, stimulated cell cycle progression in mammalian cells, and rescued proliferation of Saccharomyces cerevisiae lacking CDK activity. UL97 is not inhibited by the CDK inhibitor p21 and lacks amino acid residues conserved in the CDKs that permit the attenuation of kinase activity. Thus, UL97 represents a functional ortholog of cellular CDKs that is immune from normal CDK control mechanisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hume, Adam J -- Finkel, Jonathan S -- Kamil, Jeremy P -- Coen, Donald M -- Culbertson, Michael R -- Kalejta, Robert F -- AI26077/AI/NIAID NIH HHS/ -- GM65172/GM/NIGMS NIH HHS/ -- R56-AI064703/AI/NIAID NIH HHS/ -- T32 AI07245/AI/NIAID NIH HHS/ -- T32 CA009135-31/CA/NCI NIH HHS/ -- T32 GM007215/GM/NIGMS NIH HHS/ -- T32 GM077078-01/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2008 May 9;320(5877):797-9. doi: 10.1126/science.1152095.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Molecular Virology and McArdle Laboratory for Cancer Research, University of Wisconsin-Madison, Madison, WI 53706, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18467589" target="_blank"〉PubMed〈/a〉

    Beschreibung: Classical ecological theory suggests that the coexistence of consumer species is fostered by resource-use differences, leading to greater resource use in communities with more species. However, explicit empirical support for this idea is lacking, because resource use by species is generally confounded with other species-specific attributes. We overcame this obstacle by co-opting behavioral plasticity in food choice among a group of animal consumers, allowing us to manipulate patterns of resource use while controlling for the effects of species identity and diversity. Within an aphid-parasitoid-radish community, we created a fully factorial manipulation of consumer resource-use breadth (specialist versus generalist) and species diversity (one versus three species) and found that resource exploitation improved with greater specialist, but not generalist, diversity. Therefore, resource partitioning, and not diversity per se, fostered greater overall resource consumption in our multispecies consumer communities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Finke, Deborah L -- Snyder, William E -- New York, N.Y. -- Science. 2008 Sep 12;321(5895):1488-90. doi: 10.1126/science.1160854.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomology, Washington State University, Pullman, WA 99164, USA. finked@missouri.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18787167" target="_blank"〉PubMed〈/a〉

    Beschreibung: Cellular signaling networks have evolved to enable swift and accurate responses, even in the face of genetic or environmental perturbation. Thus, genetic screens may not identify all the genes that regulate different biological processes. Moreover, although classical screening approaches have succeeded in providing parts lists of the essential components of signaling networks, they typically do not provide much insight into the hierarchical and functional relations that exist among these components. We describe a high-throughput screen in which we used RNA interference to systematically inhibit two genes simultaneously in 17,724 combinations to identify regulators of Drosophila JUN NH(2)-terminal kinase (JNK). Using both genetic and phosphoproteomics data, we then implemented an integrative network algorithm to construct a JNK phosphorylation network, which provides structural and mechanistic insights into the systems architecture of JNK signaling.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2581798/" 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/PMC2581798/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bakal, Chris -- Linding, Rune -- Llense, Flora -- Heffern, Elleard -- Martin-Blanco, Enrique -- Pawson, Tony -- Perrimon, Norbert -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Oct 17;322(5900):453-6. doi: 10.1126/science.1158739.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School, 77 Avenue Louis Pasteur, Boston, MA 02215, USA. cbakal@receptor.med.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18927396" target="_blank"〉PubMed〈/a〉

    Beschreibung: The atypical cadherin Fat acts as a receptor for a signaling pathway that regulates growth, gene expression, and planar cell polarity. Genetic studies in Drosophila identified the four-jointed gene as a regulator of Fat signaling. We show that four-jointed encodes a protein kinase that phosphorylates serine or threonine residues within extracellular cadherin domains of Fat and its transmembrane ligand, Dachsous. Four-jointed functions in the Golgi and is the first molecularly defined kinase that phosphorylates protein domains destined to be extracellular. An acidic sequence motif (Asp-Asn-Glu) within Four-jointed was essential for its kinase activity in vitro and for its biological activity in vivo. Our results indicate that Four-jointed regulates Fat signaling by phosphorylating cadherin domains of Fat and Dachsous as they transit through the Golgi.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2562711/" 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/PMC2562711/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ishikawa, Hiroyuki O -- Takeuchi, Hideyuki -- Haltiwanger, Robert S -- Irvine, Kenneth D -- CA123071/CA/NCI NIH HHS/ -- GM061126/GM/NIGMS NIH HHS/ -- GM078620/GM/NIGMS NIH HHS/ -- R01 CA123071/CA/NCI NIH HHS/ -- R01 CA123071-02/CA/NCI NIH HHS/ -- R01 GM061126/GM/NIGMS NIH HHS/ -- R01 GM061126-08/GM/NIGMS NIH HHS/ -- R01 GM078620/GM/NIGMS NIH HHS/ -- R01 GM078620-02/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Jul 18;321(5887):401-4. doi: 10.1126/science.1158159.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Waksman Institute and Department of Molecular Biology and Biochemistry, Rutgers University, Piscataway, NJ 08854, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18635802" target="_blank"〉PubMed〈/a〉

    Beschreibung: The abundance of cellular proteins is determined largely by the rate of transcription and translation coupled with the stability of individual proteins. Although we know a great deal about global transcript abundance, little is known about global protein stability. We present a highly parallel multiplexing strategy to monitor protein turnover on a global scale by coupling flow cytometry with microarray technology to track the stability of individual proteins within a complex mixture. We demonstrated the feasibility of this approach by measuring the stability of approximately 8000 human proteins and identifying proteasome substrates. The technology provides a general platform for proteome-scale analysis of protein turnover under various physiological and disease conditions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yen, Hsueh-Chi Sherry -- Xu, Qikai -- Chou, Danny M -- Zhao, Zhenming -- Elledge, Stephen J -- AG11085/AG/NIA NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Nov 7;322(5903):918-23. doi: 10.1126/science.1160489.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Center for Genetics and Genomics, Brigham and Women's Hospital, Howard Hughes Medical Institute, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18988847" target="_blank"〉PubMed〈/a〉

    Beschreibung: Electrostatic interactions with negatively charged membranes contribute to the subcellular targeting of proteins with polybasic clusters or cationic domains. Although the anionic phospholipid phosphatidylserine is comparatively abundant, its contribution to the surface charge of individual cellular membranes is unknown, partly because of the lack of reagents to analyze its distribution in intact cells. We developed a biosensor to study the subcellular distribution of phosphatidylserine and found that it binds the cytosolic leaflets of the plasma membrane, as well as endosomes and lysosomes. The negative charge associated with the presence of phosphatidylserine directed proteins with moderately positive charge to the endocytic pathway. More strongly cationic proteins, normally associated with the plasma membrane, relocalized to endocytic compartments when the plasma membrane surface charge decreased on calcium influx.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yeung, Tony -- Gilbert, Gary E -- Shi, Jialan -- Silvius, John -- Kapus, Andras -- Grinstein, Sergio -- New York, N.Y. -- Science. 2008 Jan 11;319(5860):210-3. doi: 10.1126/science.1152066.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Cell Biology, Hospital for Sick Children, Toronto M5G 1X8, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18187657" target="_blank"〉PubMed〈/a〉

    Beschreibung: Nitric oxide acts substantially in cellular signal transduction through stimulus-coupled S-nitrosylation of cysteine residues. The mechanisms that might subserve protein denitrosylation in cellular signaling remain uncharacterized. Our search for denitrosylase activities focused on caspase-3, an exemplar of stimulus-dependent denitrosylation, and identified thioredoxin and thioredoxin reductase in a biochemical screen. In resting human lymphocytes, thioredoxin-1 actively denitrosylated cytosolic caspase-3 and thereby maintained a low steady-state amount of S-nitrosylation. Upon stimulation of Fas, thioredoxin-2 mediated denitrosylation of mitochondria-associated caspase-3, a process required for caspase-3 activation, and promoted apoptosis. Inhibition of thioredoxin-thioredoxin reductases enabled identification of additional substrates subject to endogenous S-nitrosylation. Thus, specific enzymatic mechanisms may regulate basal and stimulus-induced denitrosylation in mammalian cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2754768/" 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/PMC2754768/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benhar, Moran -- Forrester, Michael T -- Hess, Douglas T -- Stamler, Jonathan S -- P01 HL075443/HL/NHLBI NIH HHS/ -- P01 HL075443-050003/HL/NHLBI NIH HHS/ -- R01 HL059130/HL/NHLBI NIH HHS/ -- R01 HL059130-11/HL/NHLBI NIH HHS/ -- U19 ES012496/ES/NIEHS NIH HHS/ -- U19 ES012496-05/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 2008 May 23;320(5879):1050-4. doi: 10.1126/science.1158265.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Duke University Medical Center, Durham, NC 27710, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18497292" target="_blank"〉PubMed〈/a〉

    Beschreibung: We analyzed data from over 4500 elephants to show that animals in European zoos have about half the median life span of conspecifics in protected populations in range countries. This discrepancy is clearest in Asian elephants; unlike African elephants in zoos, this species' infant mortality is very high (for example, twice that seen in Burmese timber camps), and its adult survivorship in zoos has not improved significantly in recent years. One risk factor for Asian zoo elephants is being moved between institutions, with early removal from the mother tending to have additional adverse effects. Another risk factor is being born into a zoo rather than being imported from the wild, with poor adult survivorship in zoo-born Asians apparently being conferred prenatally or in early infancy. We suggest stress and/or obesity as likely causes of zoo elephants' compromised survivorship.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clubb, Ros -- Rowcliffe, Marcus -- Lee, Phyllis -- Mar, Khyne U -- Moss, Cynthia -- Mason, Georgia J -- New York, N.Y. -- Science. 2008 Dec 12;322(5908):1649. doi: 10.1126/science.1164298.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Royal Society for the Prevention of Cruelty to Animals (RSPCA), Wilberforce Way, Southwater, West Sussex, RH13 9RS, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19074339" target="_blank"〉PubMed〈/a〉

    Beschreibung: Parasitism can be a major constraint on host condition and an important selective force. Theoretical and empirical evidence shows that maternal condition affects relative investment in sons and daughters; however, the effect of parasitism on sex ratio in vertebrates is seldom considered. We demonstrate experimentally that parasitism constrains the ability of mothers to rear sons in a long-lived seabird, the European shag Phalacrocorax aristotelis. The effect contributes to the decline in offspring survival as the breeding season progresses and hence has important population-level consequences for this, and potentially other, seasonal breeders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reed, T E -- Daunt, F -- Hall, M E -- Phillips, R A -- Wanless, S -- Cunningham, E J A -- New York, N.Y. -- Science. 2008 Sep 19;321(5896):1681-2. doi: 10.1126/science.1159466.

    Beschreibung: Models of cognitive control posit a key modulatory role for the pontine locus coeruleus-norepinephrine (LC-NE) system. In nonhuman primates, phasic LC-NE activity confers adaptive adjustments in cortical gain in task-relevant brain networks, and in performance, on a trial-by-trial basis. This model has remained untested in humans. We used the pharmacological agent modafinil to promote low-tonic/high-phasic LC-NE activity in healthy humans performing a cognitive control task during event-related functional magnetic resonance imaging (fMRI). Modafanil administration was associated with decreased task-independent, tonic LC activity, increased task-related LC and prefrontal cortex (PFC) activity, and enhanced LC-PFC functional connectivity. These results confirm in humans the role of the LC-NE system in PFC function and cognitive control and suggest a mechanism for therapeutic action of procognitive noradrenergic agents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Minzenberg, Michael J -- Watrous, Andrew J -- Yoon, Jong H -- Ursu, Stefan -- Carter, Cameron S -- MH059883/MH/NIMH NIH HHS/ -- UL1 RR024146/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2008 Dec 12;322(5908):1700-2. doi: 10.1126/science.1164908.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, University of California, Davis School of Medicine, Sacramento, CA, USA. michael.minzenberg@ucdmc.ucdavis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19074351" target="_blank"〉PubMed〈/a〉

    Beschreibung: The question of how the human brain represents conceptual knowledge has been debated in many scientific fields. Brain imaging studies have shown that different spatial patterns of neural activation are associated with thinking about different semantic categories of pictures and words (for example, tools, buildings, and animals). We present a computational model that predicts the functional magnetic resonance imaging (fMRI) neural activation associated with words for which fMRI data are not yet available. This model is trained with a combination of data from a trillion-word text corpus and observed fMRI data associated with viewing several dozen concrete nouns. Once trained, the model predicts fMRI activation for thousands of other concrete nouns in the text corpus, with highly significant accuracies over the 60 nouns for which we currently have fMRI data.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mitchell, Tom M -- Shinkareva, Svetlana V -- Carlson, Andrew -- Chang, Kai-Min -- Malave, Vicente L -- Mason, Robert A -- Just, Marcel Adam -- New York, N.Y. -- Science. 2008 May 30;320(5880):1191-5. doi: 10.1126/science.1152876.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Machine Learning Department, School of Computer Science, Carnegie Mellon University, Pittsburgh, PA 15213, USA.

    Beschreibung: Duane's retraction syndrome (DRS) is a complex congenital eye movement disorder caused by aberrant innervation of the extraocular muscles by axons of brainstem motor neurons. Studying families with a variant form of the disorder (DURS2-DRS), we have identified causative heterozygous missense mutations in CHN1, a gene on chromosome 2q31 that encodes alpha2-chimaerin, a Rac guanosine triphosphatase-activating protein (RacGAP) signaling protein previously implicated in the pathfinding of corticospinal axons in mice. We found that these are gain-of-function mutations that increase alpha2-chimaerin RacGAP activity in vitro. Several of the mutations appeared to enhance alpha2-chimaerin translocation to the cell membrane or enhance its ability to self-associate. Expression of mutant alpha2-chimaerin constructs in chick embryos resulted in failure of oculomotor axons to innervate their target extraocular muscles. We conclude that alpha2-chimaerin has a critical developmental function in ocular motor axon pathfinding.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2593867/" 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/PMC2593867/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miyake, Noriko -- Chilton, John -- Psatha, Maria -- Cheng, Long -- Andrews, Caroline -- Chan, Wai-Man -- Law, Krystal -- Crosier, Moira -- Lindsay, Susan -- Cheung, Michelle -- Allen, James -- Gutowski, Nick J -- Ellard, Sian -- Young, Elizabeth -- Iannaccone, Alessandro -- Appukuttan, Binoy -- Stout, J Timothy -- Christiansen, Stephen -- Ciccarelli, Maria Laura -- Baldi, Alfonso -- Campioni, Mara -- Zenteno, Juan C -- Davenport, Dominic -- Mariani, Laura E -- Sahin, Mustafa -- Guthrie, Sarah -- Engle, Elizabeth C -- G9900837/Medical Research Council/United Kingdom -- G9900989/Medical Research Council/United Kingdom -- R01 EY015298/EY/NEI NIH HHS/ -- R01 EY015298-01/EY/NEI NIH HHS/ -- R01 EY015298-02/EY/NEI NIH HHS/ -- R01 EY015298-03/EY/NEI NIH HHS/ -- R01 EY015298-04/EY/NEI NIH HHS/ -- R01 EY015298-05/EY/NEI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Aug 8;321(5890):839-43. doi: 10.1126/science.1156121.

    Beschreibung: As the immune system develops, T cells are selected or regulated to become tolerant of self antigens and reactive against foreign antigens. In mice, the induction of such tolerance is thought to be attributable to the deletion of self-reactive cells. Here, we show that the human fetal immune system takes advantage of an additional mechanism: the generation of regulatory T cells (Tregs) that suppress fetal immune responses. We find that substantial numbers of maternal cells cross the placenta to reside in fetal lymph nodes, inducing the development of CD4+CD25highFoxP3+ Tregs that suppress fetal antimaternal immunity and persist at least until early adulthood. These findings reveal a form of antigen-specific tolerance in humans, induced in utero and probably active in regulating immune responses after birth.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2648820/" 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/PMC2648820/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mold, Jeff E -- Michaelsson, Jakob -- Burt, Trevor D -- Muench, Marcus O -- Beckerman, Karen P -- Busch, Michael P -- Lee, Tzong-Hae -- Nixon, Douglas F -- McCune, Joseph M -- AI40312/AI/NIAID NIH HHS/ -- AI68498/AI/NIAID NIH HHS/ -- DP1 OD000329/OD/NIH HHS/ -- DP1 OD000329-01/OD/NIH HHS/ -- DP1 OD000329-02/OD/NIH HHS/ -- DP1 OD000329-03/OD/NIH HHS/ -- DP1 OD000329-04/OD/NIH HHS/ -- HD00850/HD/NICHD NIH HHS/ -- HL083388/HL/NHLBI NIH HHS/ -- OD000329/OD/NIH HHS/ -- R01 HL083388/HL/NHLBI NIH HHS/ -- R01 HL083388-02/HL/NHLBI NIH HHS/ -- R37 AI040312/AI/NIAID NIH HHS/ -- R37 AI040312-09/AI/NIAID NIH HHS/ -- R37 AI040312-10/AI/NIAID NIH HHS/ -- R37 AI040312-11/AI/NIAID NIH HHS/ -- R37 AI040312-12/AI/NIAID NIH HHS/ -- R37 AI040312-13/AI/NIAID NIH HHS/ -- RR024131/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2008 Dec 5;322(5907):1562-5. doi: 10.1126/science.1164511.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Experimental Medicine, Department of Medicine, University of California at San Francisco (UCSF), San Francisco, CA 94110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19056990" target="_blank"〉PubMed〈/a〉

    Beschreibung: To equalize X-chromosome dosages between the sexes, the female mammal inactivates one of her two X chromosomes. X-chromosome inactivation (XCI) is initiated by expression of Xist, a 17-kb noncoding RNA (ncRNA) that accumulates on the X in cis. Because interacting factors have not been isolated, the mechanism by which Xist induces silencing remains unknown. We discovered a 1.6-kilobase ncRNA (RepA) within Xist and identified the Polycomb complex, PRC2, as its direct target. PRC2 is initially recruited to the X by RepA RNA, with Ezh2 serving as the RNA binding subunit. The antisense Tsix RNA inhibits this interaction. RepA depletion abolishes full-length Xist induction and trimethylation on lysine 27 of histone H3 of the X. Likewise, PRC2 deficiency compromises Xist up-regulation. Therefore, RepA, together with PRC2, is required for the initiation and spread of XCI. We conclude that a ncRNA cofactor recruits Polycomb complexes to their target locus.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2748911/" 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/PMC2748911/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhao, Jing -- Sun, Bryan K -- Erwin, Jennifer A -- Song, Ji-Joon -- Lee, Jeannie T -- R01 GM058839/GM/NIGMS NIH HHS/ -- R01 GM058839-10/GM/NIGMS NIH HHS/ -- R01 GM110090/GM/NIGMS NIH HHS/ -- R01GM58839/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Oct 31;322(5902):750-6. doi: 10.1126/science.1163045.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18974356" target="_blank"〉PubMed〈/a〉

    Beschreibung: Development of axonal tracts requires interactions between growth cones and the environment. Tracts such as the anterior commissure and internal capsule are defective in mice with null mutation of Celsr3. We generated a conditional Celsr3 allele, allowing regional inactivation. Inactivation in telencephalon, ventral forebrain, or cortex demonstrated essential roles for Celsr3 in neurons that project axons to the anterior commissure and subcerebral targets, as well as in cells that guide axons through the internal capsule. When Celsr3 was inactivated in cortex, subcerebral projections failed to grow, yet corticothalamic axons developed normally, indicating that besides guidepost cells, additional Celsr3-independent cues can assist their progression. These observations provide in vivo evidence that Celsr3-mediated interactions between axons and guidepost cells govern axonal tract formation in mammals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2746700/" 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/PMC2746700/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, Libing -- Bar, Isabelle -- Achouri, Younes -- Campbell, Kenneth -- De Backer, Olivier -- Hebert, Jean M -- Jones, Kevin -- Kessaris, Nicoletta -- de Rouvroit, Catherine Lambert -- O'Leary, Dennis -- Richardson, William D -- Goffinet, Andre M -- Tissir, Fadel -- G0501173/Medical Research Council/United Kingdom -- G0800575/Medical Research Council/United Kingdom -- G9708005/Medical Research Council/United Kingdom -- R01 MH086147/MH/NIMH NIH HHS/ -- R01 MH086147-05/MH/NIMH NIH HHS/ -- R37 NS031558/NS/NINDS NIH HHS/ -- R37 NS031558-15/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2008 May 16;320(5878):946-9. doi: 10.1126/science.1155244.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Developmental Neurobiology, Universite Catholique de Louvain, 1200 Bruxelles, Belgique.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18487195" target="_blank"〉PubMed〈/a〉

    Beschreibung: Common wisdom holds that choice decisions are based on conscious deliberations of the available information about choice options. On the basis of recent insights about unconscious influences on information processing, we tested whether automatic mental associations of undecided individuals bias future choices in a manner such that these choices reflect the evaluations implied by earlier automatic associations. With the use of a computer-based, speeded categorization task to assess automatic mental associations (i.e., associations that are activated unintentionally, difficult to control, and not necessarily endorsed at a conscious level) and self-report measures to assess consciously endorsed beliefs and choice preferences, automatic associations of undecided participants predicted changes in consciously reported beliefs and future choices over a period of 1 week. Conversely, for decided participants, consciously reported beliefs predicted changes in automatic associations and future choices over the same period. These results indicate that decision-makers sometimes have already made up their mind at an unconscious level, even when they consciously indicate that they are still undecided.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Galdi, Silvia -- Arcuri, Luciano -- Gawronski, Bertram -- New York, N.Y. -- Science. 2008 Aug 22;321(5892):1100-2. doi: 10.1126/science.1160769.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental Psychology and Socialization, University of Padova, Via Venezia 8, 35131 Padova, Italy. silvia.galdi@unipd.it〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18719288" target="_blank"〉PubMed〈/a〉

    Beschreibung: Angiogenesis-mediated progression of micrometastasis to lethal macrometastasis is the major cause of death in cancer patients. Here, using mouse models of pulmonary metastasis, we identify bone marrow (BM)-derived endothelial progenitor cells (EPCs) as critical regulators of this angiogenic switch. We show that tumors induce expression of the transcription factor Id1 in the EPCs and that suppression of Id1 after metastatic colonization blocked EPC mobilization, caused angiogenesis inhibition, impaired pulmonary macrometastases, and increased survival of tumor-bearing animals. These findings establish the role of EPCs in metastatic progression in preclinical models and suggest that selective targeting of EPCs may merit investigation as a therapy for cancer patients with lung metastases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gao, Dingcheng -- Nolan, Daniel J -- Mellick, Albert S -- Bambino, Kathryn -- McDonnell, Kevin -- Mittal, Vivek -- New York, N.Y. -- Science. 2008 Jan 11;319(5860):195-8. doi: 10.1126/science.1150224.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Genome Research Center, Cold Spring Harbor Laboratory, Cold Spring Harbor, NY 11724, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18187653" target="_blank"〉PubMed〈/a〉

    Beschreibung: The functional complexity of the human transcriptome is not yet fully elucidated. We report a high-throughput sequence of the human transcriptome from a human embryonic kidney and a B cell line. We used shotgun sequencing of transcripts to generate randomly distributed reads. Of these, 50% mapped to unique genomic locations, of which 80% corresponded to known exons. We found that 66% of the polyadenylated transcriptome mapped to known genes and 34% to nonannotated genomic regions. On the basis of known transcripts, RNA-Seq can detect 25% more genes than can microarrays. A global survey of messenger RNA splicing events identified 94,241 splice junctions (4096 of which were previously unidentified) and showed that exon skipping is the most prevalent form of alternative splicing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sultan, Marc -- Schulz, Marcel H -- Richard, Hugues -- Magen, Alon -- Klingenhoff, Andreas -- Scherf, Matthias -- Seifert, Martin -- Borodina, Tatjana -- Soldatov, Aleksey -- Parkhomchuk, Dmitri -- Schmidt, Dominic -- O'Keeffe, Sean -- Haas, Stefan -- Vingron, Martin -- Lehrach, Hans -- Yaspo, Marie-Laure -- New York, N.Y. -- Science. 2008 Aug 15;321(5891):956-60. doi: 10.1126/science.1160342.

    Beschreibung: To find inherited causes of autism-spectrum disorders, we studied families in which parents share ancestors, enhancing the role of inherited factors. We mapped several loci, some containing large, inherited, homozygous deletions that are likely mutations. The largest deletions implicated genes, including PCDH10 (protocadherin 10) and DIA1 (deleted in autism1, or c3orf58), whose level of expression changes in response to neuronal activity, a marker of genes involved in synaptic changes that underlie learning. A subset of genes, including NHE9 (Na+/H+ exchanger 9), showed additional potential mutations in patients with unrelated parents. Our findings highlight the utility of "homozygosity mapping" in heterogeneous disorders like autism but also suggest that defective regulation of gene expression after neural activity may be a mechanism common to seemingly diverse autism mutations.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2586171/" 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/PMC2586171/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morrow, Eric M -- Yoo, Seung-Yun -- Flavell, Steven W -- Kim, Tae-Kyung -- Lin, Yingxi -- Hill, Robert Sean -- Mukaddes, Nahit M -- Balkhy, Soher -- Gascon, Generoso -- Hashmi, Asif -- Al-Saad, Samira -- Ware, Janice -- Joseph, Robert M -- Greenblatt, Rachel -- Gleason, Danielle -- Ertelt, Julia A -- Apse, Kira A -- Bodell, Adria -- Partlow, Jennifer N -- Barry, Brenda -- Yao, Hui -- Markianos, Kyriacos -- Ferland, Russell J -- Greenberg, Michael E -- Walsh, Christopher A -- 1K01MH71801/MH/NIMH NIH HHS/ -- 1K23MH080954-01/MH/NIMH NIH HHS/ -- 1R01 MH083565/MH/NIMH NIH HHS/ -- 5P30HD018655-26/HD/NICHD NIH HHS/ -- 5R01NS048276-05/NS/NINDS NIH HHS/ -- K01 MH071801/MH/NIMH NIH HHS/ -- K01 MH071801-04/MH/NIMH NIH HHS/ -- K01 MH071801-05/MH/NIMH NIH HHS/ -- K23 MH080954/MH/NIMH NIH HHS/ -- K23 MH080954-01/MH/NIMH NIH HHS/ -- MH64547/MH/NIMH NIH HHS/ -- N01-HG-65403/HG/NHGRI NIH HHS/ -- R01 MH083565/MH/NIMH NIH HHS/ -- R01 NS048276/NS/NINDS NIH HHS/ -- R01 NS048276-01/NS/NINDS NIH HHS/ -- R01 NS048276-02/NS/NINDS NIH HHS/ -- R01 NS048276-03/NS/NINDS NIH HHS/ -- R01 NS048276-04/NS/NINDS NIH HHS/ -- R01 NS048276-05/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Jul 11;321(5886):218-23. doi: 10.1126/science.1157657.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Genetics, Children's Hospital Boston and Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18621663" target="_blank"〉PubMed〈/a〉

    Beschreibung: Almost two decades after CFTR was identified as the gene responsible for cystic fibrosis (CF), we still lack answers to many questions about the pathogenesis of the disease, and it remains incurable. Mice with a disrupted CFTR gene have greatly facilitated CF studies, but the mutant mice do not develop the characteristic manifestations of human CF, including abnormalities of the pancreas, lung, intestine, liver, and other organs. Because pigs share many anatomical and physiological features with humans, we generated pigs with a targeted disruption of both CFTR alleles. Newborn pigs lacking CFTR exhibited defective chloride transport and developed meconium ileus, exocrine pancreatic destruction, and focal biliary cirrhosis, replicating abnormalities seen in newborn humans with CF. The pig model may provide opportunities to address persistent questions about CF pathogenesis and accelerate discovery of strategies for prevention and treatment.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2570747/" 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/PMC2570747/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rogers, Christopher S -- Stoltz, David A -- Meyerholz, David K -- Ostedgaard, Lynda S -- Rokhlina, Tatiana -- Taft, Peter J -- Rogan, Mark P -- Pezzulo, Alejandro A -- Karp, Philip H -- Itani, Omar A -- Kabel, Amanda C -- Wohlford-Lenane, Christine L -- Davis, Greg J -- Hanfland, Robert A -- Smith, Tony L -- Samuel, Melissa -- Wax, David -- Murphy, Clifton N -- Rieke, August -- Whitworth, Kristin -- Uc, Aliye -- Starner, Timothy D -- Brogden, Kim A -- Shilyansky, Joel -- McCray, Paul B Jr -- Zabner, Joseph -- Prather, Randall S -- Welsh, Michael J -- AI076671/AI/NIAID NIH HHS/ -- DK54759/DK/NIDDK NIH HHS/ -- HL07638/HL/NHLBI NIH HHS/ -- HL51670/HL/NHLBI NIH HHS/ -- K08 AI076671/AI/NIAID NIH HHS/ -- K08 AI076671-01/AI/NIAID NIH HHS/ -- P01 HL051670/HL/NHLBI NIH HHS/ -- P01 HL051670-15/HL/NHLBI NIH HHS/ -- P30 DK054759/DK/NIDDK NIH HHS/ -- P30 DK054759-10/DK/NIDDK NIH HHS/ -- P30 DK054759-109004/DK/NIDDK NIH HHS/ -- R01 DK051315/DK/NIDDK NIH HHS/ -- T32 HL007638/HL/NHLBI NIH HHS/ -- T32 HL007638-23/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Sep 26;321(5897):1837-41. doi: 10.1126/science.1163600.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, Roy J. and Lucille A.

    Beschreibung: Recombination plays a crucial role in meiosis, ensuring the proper segregation of chromosomes. Recent linkage disequilibrium (LD) and sperm-typing studies suggest that recombination rates vary tremendously across the human genome, with most events occurring in narrow "hotspots." To examine variation in fine-scale recombination patterns among individuals, we used dense, genome-wide single-nucleotide polymorphism data collected in nuclear families to localize crossovers with high spatial resolution. This analysis revealed that overall recombination hotspot usage is similar in males and females, with individual hotspots often active in both sexes. Across the genome, roughly 60% of crossovers occurred in hotspots inferred from LD studies. Notably, however, we found extensive and heritable variation among both males and females in the proportion of crossovers occurring in these hotspots.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coop, Graham -- Wen, Xiaoquan -- Ober, Carole -- Pritchard, Jonathan K -- Przeworski, Molly -- GM83098/GM/NIGMS NIH HHS/ -- HD21244/HD/NICHD NIH HHS/ -- HG002772/HG/NHGRI NIH HHS/ -- HL56399/HL/NHLBI NIH HHS/ -- HL56533/HL/NHLBI NIH HHS/ -- R01 HG002772/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2008 Mar 7;319(5868):1395-8. doi: 10.1126/science.1151851.

    Beschreibung: The paucity of polymorphisms in single-copy genes on the Y chromosome of Drosophila contrasts with data indicating that this chromosome has polymorphic phenotypic effects on sex ratio, temperature sensitivity, behavior, and fitness. We show that the Y chromosome of D. melanogaster harbors substantial genetic diversity in the form of polymorphisms for genetic elements that differentially affect the expression of hundreds of X-linked and autosomal genes. The affected genes are more highly expressed in males, more meagerly expressed in females, and more highly divergent between species. Functionally, they affect microtubule stability, lipid and mitochondrial metabolism, and the thermal sensitivity of spermatogenesis. Our findings provide a mechanism for adaptive phenotypic variation associated with the Y chromosome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lemos, Bernardo -- Araripe, Luciana O -- Hartl, Daniel L -- GM065169/GM/NIGMS NIH HHS/ -- GM068465/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2008 Jan 4;319(5859):91-3. doi: 10.1126/science.1148861.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Organismic and Evolutionary Biology, Harvard University, 16 Divinity Avenue, Cambridge, MA 02138, USA. blemos@oeb.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18174442" target="_blank"〉PubMed〈/a〉

    Beschreibung: RNA polymerases are highly regulated molecular machines. We present a method (global run-on sequencing, GRO-seq) that maps the position, amount, and orientation of transcriptionally engaged RNA polymerases genome-wide. In this method, nuclear run-on RNA molecules are subjected to large-scale parallel sequencing and mapped to the genome. We show that peaks of promoter-proximal polymerase reside on approximately 30% of human genes, transcription extends beyond pre-messenger RNA 3' cleavage, and antisense transcription is prevalent. Additionally, most promoters have an engaged polymerase upstream and in an orientation opposite to the annotated gene. This divergent polymerase is associated with active genes but does not elongate effectively beyond the promoter. These results imply that the interplay between polymerases and regulators over broad promoter regions dictates the orientation and efficiency of productive transcription.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2833333/" 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/PMC2833333/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Core, Leighton J -- Waterfall, Joshua J -- Lis, John T -- GM25232/GM/NIGMS NIH HHS/ -- R01 GM025232/GM/NIGMS NIH HHS/ -- R01 GM025232-32/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2008 Dec 19;322(5909):1845-8. doi: 10.1126/science.1162228.

    Beschreibung: Alcohol dependence is a major public health challenge in need of new treatments. As alcoholism evolves, stress systems in the brain play an increasing role in motivating continued alcohol use and relapse. We investigated the role of the neurokinin 1 receptor (NK1R), a mediator of behavioral stress responses, in alcohol dependence and treatment. In preclinical studies, mice genetically deficient in NK1R showed a marked decrease in voluntary alcohol consumption and had an increased sensitivity to the sedative effects of alcohol. In a randomized controlled experimental study, we treated recently detoxified alcoholic inpatients with an NK1R antagonist (LY686017; n = 25) or placebo (n = 25). LY686017 suppressed spontaneous alcohol cravings, improved overall well-being, blunted cravings induced by a challenge procedure, and attenuated concomitant cortisol responses. Brain functional magnetic resonance imaging responses to affective stimuli likewise suggested beneficial LY686017 effects. Thus, as assessed by these surrogate markers of efficacy, NK1R antagonism warrants further investigation as a treatment in alcoholism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉George, David T -- Gilman, Jodi -- Hersh, Jacqueline -- Thorsell, Annika -- Herion, David -- Geyer, Christopher -- Peng, Xiaomei -- Kielbasa, William -- Rawlings, Robert -- Brandt, John E -- Gehlert, Donald R -- Tauscher, Johannes T -- Hunt, Stephen P -- Hommer, Daniel -- Heilig, Markus -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2008 Mar 14;319(5869):1536-9. doi: 10.1126/science.1153813.

    Beschreibung: A central goal of evolutionary biology is to identify the genes and evolutionary forces that cause speciation, the emergence of reproductive isolation between populations. Despite the identification of several genes that cause hybrid sterility or inviability-many of which have evolved rapidly under positive Darwinian selection-little is known about the ecological or genomic forces that drive the evolution of postzygotic isolation. Here, we show that the same gene, Overdrive, causes both male sterility and segregation distortion in F1 hybrids between the Bogota and U.S. subspecies of Drosophila pseudoobscura. This segregation distorter gene is essential for hybrid sterility, a strong reproductive barrier between these young taxa. Our results suggest that genetic conflict may be an important evolutionary force in speciation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2628965/" 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/PMC2628965/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Phadnis, Nitin -- Orr, H Allen -- GM51932/GM/NIGMS NIH HHS/ -- R01 GM051932/GM/NIGMS NIH HHS/ -- R01 GM051932-13/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Jan 16;323(5912):376-9. doi: 10.1126/science.1163934.

    Beschreibung: Speciation genes restrict gene flow between the incipient species and related taxa. Three decades ago, we mapped a mammalian speciation gene, hybrid sterility 1 (Hst1), in the intersubspecific hybrids of house mouse. Here, we identify this gene as Prdm9, encoding a histone H3 lysine 4 trimethyltransferase. We rescued infertility in male hybrids with bacterial artificial chromosomes carrying Prdm9 from a strain with the "fertility" Hst1(f) allele. Sterile hybrids display down-regulated microrchidia 2B (Morc2b) and fail to compartmentalize gammaH2AX into the pachynema sex (XY) body. These defects, seen also in Prdm9-null mutants, are rescued by the Prdm9 transgene. Identification of a vertebrate hybrid sterility gene reveals a role for epigenetics in speciation and opens a window to a hybrid sterility gene network.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mihola, Ondrej -- Trachtulec, Zdenek -- Vlcek, Cestmir -- Schimenti, John C -- Forejt, Jiri -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Jan 16;323(5912):373-5. doi: 10.1126/science.1163601.

    Beschreibung: A number of large noncoding RNAs (ncRNAs) epigenetically silence genes through unknown mechanisms. The Air ncRNA is imprinted--monoallelically expressed from the paternal allele. Air is required for allele-specific silencing of the cis-linked Slc22a3, Slc22a2, and Igf2r genes in mouse placenta. We show that Air interacts with the Slc22a3 promoter chromatin and the H3K9 histone methyltransferase G9a in placenta. Air accumulates at the Slc22a3 promoter in correlation with localized H3K9 methylation and transcriptional repression. Genetic ablation of G9a results in nonimprinted, biallelic transcription of Slc22a3. Truncated Air fails to accumulate at the Slc22a3 promoter, which results in reduced G9a recruitment and biallelic transcription. Our results suggest that Air, and potentially other large ncRNAs, target repressive histone-modifying activities through molecular interaction with specific chromatin domains to epigenetically silence transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nagano, Takashi -- Mitchell, Jennifer A -- Sanz, Lionel A -- Pauler, Florian M -- Ferguson-Smith, Anne C -- Feil, Robert -- Fraser, Peter -- BB/D014050/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBS/E/B/0000C151/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0400156/Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2008 Dec 12;322(5908):1717-20. doi: 10.1126/science.1163802.

    Beschreibung: Chromosomal rearrangements that create gene fusions are common features of human tumors. The prevailing view is that the resultant chimeric transcripts and proteins are abnormal, tumor-specific products that provide tumor cells with a growth and/or survival advantage. We show that normal endometrial stromal cells contain a specific chimeric RNA joining 5' exons of the JAZF1 gene on chromosome 7p15 to 3' exons of the Polycomb group gene JJAZ1/SUZ12 on chromosome 17q11 and that this RNA is translated into JAZF1-JJAZ1, a protein with anti-apoptotic activity. The JAZF1-JJAZ1 RNA appears to arise from physiologically regulated trans-splicing between precursor messenger RNAs for JAZF1 and JJAZ1. The chimeric RNA and protein are identical to those produced from a gene fusion found in human endometrial stromal tumors. These observations suggest that certain gene fusions may be pro-neoplastic owing to constitutive expression of chimeric gene products normally generated by trans-splicing of RNAs in developing tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Hui -- Wang, Jinglan -- Mor, Gil -- Sklar, Jeffrey -- R01 CA85995/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2008 Sep 5;321(5894):1357-61. doi: 10.1126/science.1156725.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Yale University School of Medicine, New Haven, CT 06520, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18772439" target="_blank"〉PubMed〈/a〉

    Beschreibung: The Paleo-Eskimo Saqqaq and Independence I cultures, documented from archaeological remains in Northern Canada and Greenland, represent the earliest human expansion into the New World's northern extremes. However, their origin and genetic relationship to later cultures are unknown. We sequenced a mitochondrial genome from a Paleo-Eskimo human by using 3400-to 4500-year-old frozen hair excavated from an early Greenlandic Saqqaq settlement. The sample is distinct from modern Native Americans and Neo-Eskimos, falling within haplogroup D2a1, a group previously observed among modern Aleuts and Siberian Sireniki Yuit. This result suggests that the earliest migrants into the New World's northern extremes derived from populations in the Bering Sea area and were not directly related to Native Americans or the later Neo-Eskimos that replaced them.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gilbert, M Thomas P -- Kivisild, Toomas -- Gronnow, Bjarne -- Andersen, Pernille K -- Metspalu, Ene -- Reidla, Maere -- Tamm, Erika -- Axelsson, Erik -- Gotherstrom, Anders -- Campos, Paula F -- Rasmussen, Morten -- Metspalu, Mait -- Higham, Thomas F G -- Schwenninger, Jean-Luc -- Nathan, Roger -- De Hoog, Cees-Jan -- Koch, Anders -- Moller, Lone Nukaaraq -- Andreasen, Claus -- Meldgaard, Morten -- Villems, Richard -- Bendixen, Christian -- Willerslev, Eske -- New York, N.Y. -- Science. 2008 Jun 27;320(5884):1787-9. doi: 10.1126/science.1159750.
