    Functional divergence of former alleles in an ancient asexual invertebrate (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2007-10-13
    Beschreibung: Theory suggests it should be difficult for asexual organisms to adapt to a changing environment because genetic diversity can only arise from mutations accumulating within direct antecedents and not through sexual exchange. In an asexual microinvertebrate, the bdelloid rotifer, we have observed a mechanism by which such organisms could acquire the diversity needed for adaptation. Gene copies most likely representing former alleles have diverged in function so that the proteins they encode play complementary roles in survival of dry conditions. One protein prevents desiccation-sensitive enzymes from aggregating during drying, whereas its counterpart does not have this activity, but is able to associate with phospholipid bilayers and is potentially involved in maintenance of membrane integrity. The functional divergence of former alleles observed here suggests that adoption of asexual reproduction could itself be an evolutionary mechanism for the generation of diversity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pouchkina-Stantcheva, Natalia N -- McGee, Brian M -- Boschetti, Chiara -- Tolleter, Dimitri -- Chakrabortee, Sohini -- Popova, Antoaneta V -- Meersman, Filip -- Macherel, David -- Hincha, Dirk K -- Tunnacliffe, Alan -- New York, N.Y. -- Science. 2007 Oct 12;318(5848):268-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Biotechnology, University of Cambridge, Tennis Court Road, Cambridge CB2 1QT, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17932297" target="_blank"〉PubMed〈/a〉

    Widespread lateral gene transfer from intracellular bacteria to multicellular eukaryotes (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2007-09-01
    Beschreibung: Although common among bacteria, lateral gene transfer-the movement of genes between distantly related organisms-is thought to occur only rarely between bacteria and multicellular eukaryotes. However, the presence of endosymbionts, such as Wolbachia pipientis, within some eukaryotic germlines may facilitate bacterial gene transfers to eukaryotic host genomes. We therefore examined host genomes for evidence of gene transfer events from Wolbachia bacteria to their hosts. We found and confirmed transfers into the genomes of four insect and four nematode species that range from nearly the entire Wolbachia genome (〉1 megabase) to short (〈500 base pairs) insertions. Potential Wolbachia-to-host transfers were also detected computationally in three additional sequenced insect genomes. We also show that some of these inserted Wolbachia genes are transcribed within eukaryotic cells lacking endosymbionts. Therefore, heritable lateral gene transfer occurs into eukaryotic hosts from their prokaryote symbionts, potentially providing a mechanism for acquisition of new genes and functions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dunning Hotopp, Julie C -- Clark, Michael E -- Oliveira, Deodoro C S G -- Foster, Jeremy M -- Fischer, Peter -- Munoz Torres, Monica C -- Giebel, Jonathan D -- Kumar, Nikhil -- Ishmael, Nadeeza -- Wang, Shiliang -- Ingram, Jessica -- Nene, Rahul V -- Shepard, Jessica -- Tomkins, Jeffrey -- Richards, Stephen -- Spiro, David J -- Ghedin, Elodie -- Slatko, Barton E -- Tettelin, Herve -- Werren, John H -- New York, N.Y. -- Science. 2007 Sep 21;317(5845):1753-6.

    Common sequence polymorphisms shaping genetic diversity in Arabidopsis thaliana (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2007-07-21
    Beschreibung: The genomes of individuals from the same species vary in sequence as a result of different evolutionary processes. To examine the patterns of, and the forces shaping, sequence variation in Arabidopsis thaliana, we performed high-density array resequencing of 20 diverse strains (accessions). More than 1 million nonredundant single-nucleotide polymorphisms (SNPs) were identified at moderate false discovery rates (FDRs), and approximately 4% of the genome was identified as being highly dissimilar or deleted relative to the reference genome sequence. Patterns of polymorphism are highly nonrandom among gene families, with genes mediating interaction with the biotic environment having exceptional polymorphism levels. At the chromosomal scale, regional variation in polymorphism was readily apparent. A scan for recent selective sweeps revealed several candidate regions, including a notable example in which almost all variation was removed in a 500-kilobase window. Analyzing the polymorphisms we describe in larger sets of accessions will enable a detailed understanding of forces shaping population-wide sequence variation in A. thaliana.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clark, Richard M -- Schweikert, Gabriele -- Toomajian, Christopher -- Ossowski, Stephan -- Zeller, Georg -- Shinn, Paul -- Warthmann, Norman -- Hu, Tina T -- Fu, Glenn -- Hinds, David A -- Chen, Huaming -- Frazer, Kelly A -- Huson, Daniel H -- Scholkopf, Bernhard -- Nordborg, Magnus -- Ratsch, Gunnar -- Ecker, Joseph R -- Weigel, Detlef -- New York, N.Y. -- Science. 2007 Jul 20;317(5836):338-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Max Planck Institute for Developmental Biology, 72076 Tubingen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17641193" target="_blank"〉PubMed〈/a〉

    An X chromosome gene, WTX, is commonly inactivated in Wilms tumor (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2007-01-06
    Beschreibung: Wilms tumor is a pediatric kidney cancer associated with inactivation of the WT1 tumor-suppressor gene in 5 to 10% of cases. Using a high-resolution screen for DNA copy-number alterations in Wilms tumor, we identified somatic deletions targeting a previously uncharacterized gene on the X chromosome. This gene, which we call WTX, is inactivated in approximately one-third of Wilms tumors (15 of 51 tumors). Tumors with mutations in WTX lack WT1 mutations, and both genes share a restricted temporal and spatial expression pattern in normal renal precursors. In contrast to biallelic inactivation of autosomal tumor-suppressor genes, WTX is inactivated by a monoallelic "single-hit" event targeting the single X chromosome in tumors from males and the active X chromosome in tumors from females.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rivera, Miguel N -- Kim, Woo Jae -- Wells, Julie -- Driscoll, David R -- Brannigan, Brian W -- Han, Moonjoo -- Kim, James C -- Feinberg, Andrew P -- Gerald, William L -- Vargas, Sara O -- Chin, Lynda -- Iafrate, A John -- Bell, Daphne W -- Haber, Daniel A -- P01-CA101942/CA/NCI NIH HHS/ -- R37 CA054358/CA/NCI NIH HHS/ -- R37 CA054358-17/CA/NCI NIH HHS/ -- R37-CA058596/CA/NCI NIH HHS/ -- T32-CA009216/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2007 Feb 2;315(5812):642-5.

    Free-solution, label-free molecular interactions studied by back-scattering interferometry (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2007-09-22
    Beschreibung: Free-solution, label-free molecular interactions were investigated with back-scattering interferometry in a simple optical train composed of a helium-neon laser, a microfluidic channel, and a position sensor. Molecular binding interactions between proteins, ions and protein, and small molecules and protein, were determined with high dynamic range dissociation constants (Kd spanning six decades) and unmatched sensitivity (picomolar Kd's and detection limits of 10,000s of molecules). With this technique, equilibrium dissociation constants were quantified for protein A and immunoglobulin G, interleukin-2 with its monoclonal antibody, and calmodulin with calcium ion Ca2+, a small molecule inhibitor, the protein calcineurin, and the M13 peptide. The high sensitivity of back-scattering interferometry and small volumes of microfluidics allowed the entire calmodulin assay to be performed with 200 picomoles of solute.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bornhop, Darryl J -- Latham, Joey C -- Kussrow, Amanda -- Markov, Dmitry A -- Jones, Richard D -- Sorensen, Henrik S -- R-01 EB0003537-01A2/EB/NIBIB NIH HHS/ -- T32 GM065086/GM/NIGMS NIH HHS/ -- T32-EY07135/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2007 Sep 21;317(5845):1732-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Vanderbilt Institute of Chemical Biology, Vanderbilt University, VU Station B 351822, Nashville, TN 37235-1822, USA. darryl.bornhop@vanderbilt.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17885132" target="_blank"〉PubMed〈/a〉

    The Fusarium graminearum genome reveals a link between localized polymorphism and pathogen specialization (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2007-09-08
    Beschreibung: We sequenced and annotated the genome of the filamentous fungus Fusarium graminearum, a major pathogen of cultivated cereals. Very few repetitive sequences were detected, and the process of repeat-induced point mutation, in which duplicated sequences are subject to extensive mutation, may partially account for the reduced repeat content and apparent low number of paralogous (ancestrally duplicated) genes. A second strain of F. graminearum contained more than 10,000 single-nucleotide polymorphisms, which were frequently located near telomeres and within other discrete chromosomal segments. Many highly polymorphic regions contained sets of genes implicated in plant-fungus interactions and were unusually divergent, with higher rates of recombination. These regions of genome innovation may result from selection due to interactions of F. graminearum with its plant hosts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cuomo, Christina A -- Guldener, Ulrich -- Xu, Jin-Rong -- Trail, Frances -- Turgeon, B Gillian -- Di Pietro, Antonio -- Walton, Jonathan D -- Ma, Li-Jun -- Baker, Scott E -- Rep, Martijn -- Adam, Gerhard -- Antoniw, John -- Baldwin, Thomas -- Calvo, Sarah -- Chang, Yueh-Long -- Decaprio, David -- Gale, Liane R -- Gnerre, Sante -- Goswami, Rubella S -- Hammond-Kosack, Kim -- Harris, Linda J -- Hilburn, Karen -- Kennell, John C -- Kroken, Scott -- Magnuson, Jon K -- Mannhaupt, Gertrud -- Mauceli, Evan -- Mewes, Hans-Werner -- Mitterbauer, Rudolf -- Muehlbauer, Gary -- Munsterkotter, Martin -- Nelson, David -- O'donnell, Kerry -- Ouellet, Therese -- Qi, Weihong -- Quesneville, Hadi -- Roncero, M Isabel G -- Seong, Kye-Yong -- Tetko, Igor V -- Urban, Martin -- Waalwijk, Cees -- Ward, Todd J -- Yao, Jiqiang -- Birren, Bruce W -- Kistler, H Corby -- U54 HG003067/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2007 Sep 7;317(5843):1400-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Broad Institute of the Massachusetts Institute of Technology and Harvard, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17823352" target="_blank"〉PubMed〈/a〉

    Serine-7 of the RNA polymerase II CTD is specifically required for snRNA gene expression (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2007-12-15
    Beschreibung: RNA polymerase II (Pol II) transcribes genes that encode proteins and noncoding small nuclear RNAs (snRNAs). The carboxyl-terminal repeat domain (CTD) of the largest subunit of mammalian RNA Pol II, comprising tandem repeats of the heptapeptide consensus Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7, is required for expression of both gene types. We show that mutation of serine-7 to alanine causes a specific defect in snRNA gene expression. We also present evidence that phosphorylation of serine-7 facilitates interaction with the snRNA gene-specific Integrator complex. These findings assign a biological function to this amino acid and highlight a gene type-specific requirement for a residue within the CTD heptapeptide, supporting the existence of a CTD code.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2263945/" 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/PMC2263945/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Egloff, Sylvain -- O'Reilly, Dawn -- Chapman, Rob D -- Taylor, Alice -- Tanzhaus, Katrin -- Pitts, Laura -- Eick, Dirk -- Murphy, Shona -- 072107/Wellcome Trust/United Kingdom -- 081312/Wellcome Trust/United Kingdom -- G0400653/Medical Research Council/United Kingdom -- G0400653(71330)/Medical Research Council/United Kingdom -- G9826944/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2007 Dec 14;318(5857):1777-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sir William Dunn School of Pathology, University of Oxford, South Parks Road, Oxford OX1 3RE, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18079403" target="_blank"〉PubMed〈/a〉

    A Late Triassic dinosauromorph assemblage from New Mexico and the rise of dinosaurs (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2007-07-21
    Beschreibung: It has generally been thought that the first dinosaurs quickly replaced more archaic Late Triassic faunas, either by outcompeting them or when the more archaic faunas suddenly became extinct. Fossils from the Hayden Quarry, in the Upper Triassic Chinle Formation of New Mexico, and an analysis of other regional Upper Triassic assemblages instead imply that the transition was gradual. Some dinosaur relatives preserved in this Chinle assemblage belong to groups previously known only from the Middle and lowermost Upper Triassic outside North America. Thus, the transition may have extended for 15 to 20 million years and was probably diachronous at different paleolatitudes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Irmis, Randall B -- Nesbitt, Sterling J -- Padian, Kevin -- Smith, Nathan D -- Turner, Alan H -- Woody, Daniel -- Downs, Alex -- New York, N.Y. -- Science. 2007 Jul 20;317(5836):358-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Museum of Paleontology and Department of Integrative Biology, University of California, Berkeley, CA 94720-4780, USA. irmis@berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17641198" target="_blank"〉PubMed〈/a〉

    Apoptosis initiated when BH3 ligands engage multiple Bcl-2 homologs, not Bax or Bak (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2007-02-10
    Beschreibung: A central issue in the regulation of apoptosis by the Bcl-2 family is whether its BH3-only members initiate apoptosis by directly binding to the essential cell-death mediators Bax and Bak, or whether they can act indirectly, by engaging their pro-survival Bcl-2-like relatives. Contrary to the direct-activation model, we show that Bax and Bak can mediate apoptosis without discernable association with the putative BH3-only activators (Bim, Bid, and Puma), even in cells with no Bim or Bid and reduced Puma. Our results indicate that BH3-only proteins induce apoptosis at least primarily by engaging the multiple pro-survival relatives guarding Bax and Bak.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willis, Simon N -- Fletcher, Jamie I -- Kaufmann, Thomas -- van Delft, Mark F -- Chen, Lin -- Czabotar, Peter E -- Ierino, Helen -- Lee, Erinna F -- Fairlie, W Douglas -- Bouillet, Philippe -- Strasser, Andreas -- Kluck, Ruth M -- Adams, Jerry M -- Huang, David C S -- CA43540/CA/NCI NIH HHS/ -- CA80188/CA/NCI NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2007 Feb 9;315(5813):856-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Walter and Eliza Hall Institute of Medical Research, 1G Royal Parade, Parkville, Victoria 3050, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17289999" target="_blank"〉PubMed〈/a〉

    Beschreibung: Mutations affecting the BRCT domains of the breast cancer-associated tumor suppressor BRCA1 disrupt the recruitment of this protein to DNA double-strand breaks (DSBs). The molecular structures at DSBs recognized by BRCA1 are presently unknown. We report the interaction of the BRCA1 BRCT domain with RAP80, a ubiquitin-binding protein. RAP80 targets a complex containing the BRCA1-BARD1 (BRCA1-associated ring domain protein 1) E3 ligase and the deubiquitinating enzyme (DUB) BRCC36 to MDC1-gammaH2AX-dependent lysine(6)- and lysine(63)-linked ubiquitin polymers at DSBs. These events are required for cell cycle checkpoint and repair responses to ionizing radiation, implicating ubiquitin chain recognition and turnover in the BRCA1-mediated repair of DSBs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2706583/" 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/PMC2706583/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sobhian, Bijan -- Shao, Genze -- Lilli, Dana R -- Culhane, Aedin C -- Moreau, Lisa A -- Xia, Bing -- Livingston, David M -- Greenberg, Roger A -- K08 CA106597/CA/NCI NIH HHS/ -- K08 CA106597-01A2/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2007 May 25;316(5828):1198-202.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana-Farber Cancer Institute and Department of Genetics and Department of Medicine, Harvard Medical School, 44 Binney Street, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17525341" target="_blank"〉PubMed〈/a〉
