    PRDM9 is a major determinant of meiotic recombination hotspots in humans and mice (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-02
    Description: Meiotic recombination events cluster into narrow segments of the genome, defined as hotspots. Here, we demonstrate that a major player for hotspot specification is the Prdm9 gene. First, two mouse strains that differ in hotspot usage are polymorphic for the zinc finger DNA binding array of PRDM9. Second, the human consensus PRDM9 allele is predicted to recognize the 13-mer motif enriched at human hotspots; this DNA binding specificity is verified by in vitro studies. Third, allelic variants of PRDM9 zinc fingers are significantly associated with variability in genome-wide hotspot usage among humans. Our results provide a molecular basis for the distribution of meiotic recombination in mammals, in which the binding of PRDM9 to specific DNA sequences targets the initiation of recombination at specific locations in the genome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4295902/" 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/PMC4295902/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baudat, F -- Buard, J -- Grey, C -- Fledel-Alon, A -- Ober, C -- Przeworski, M -- Coop, G -- de Massy, B -- 03S1/PHS HHS/ -- GM83098/GM/NIGMS NIH HHS/ -- HD21244/HD/NICHD NIH HHS/ -- HL085197/HL/NHLBI NIH HHS/ -- R01 GM083098/GM/NIGMS NIH HHS/ -- R01 HD021244/HD/NICHD NIH HHS/ -- R01 HL085197/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Feb 12;327(5967):836-40. doi: 10.1126/science.1183439.

    A draft sequence of the Neandertal genome (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-05-08
    Description: Neandertals, the closest evolutionary relatives of present-day humans, lived in large parts of Europe and western Asia before disappearing 30,000 years ago. We present a draft sequence of the Neandertal genome composed of more than 4 billion nucleotides from three individuals. Comparisons of the Neandertal genome to the genomes of five present-day humans from different parts of the world identify a number of genomic regions that may have been affected by positive selection in ancestral modern humans, including genes involved in metabolism and in cognitive and skeletal development. We show that Neandertals shared more genetic variants with present-day humans in Eurasia than with present-day humans in sub-Saharan Africa, suggesting that gene flow from Neandertals into the ancestors of non-Africans occurred before the divergence of Eurasian groups from each other.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Green, Richard E -- Krause, Johannes -- Briggs, Adrian W -- Maricic, Tomislav -- Stenzel, Udo -- Kircher, Martin -- Patterson, Nick -- Li, Heng -- Zhai, Weiwei -- Fritz, Markus Hsi-Yang -- Hansen, Nancy F -- Durand, Eric Y -- Malaspinas, Anna-Sapfo -- Jensen, Jeffrey D -- Marques-Bonet, Tomas -- Alkan, Can -- Prufer, Kay -- Meyer, Matthias -- Burbano, Hernan A -- Good, Jeffrey M -- Schultz, Rigo -- Aximu-Petri, Ayinuer -- Butthof, Anne -- Hober, Barbara -- Hoffner, Barbara -- Siegemund, Madlen -- Weihmann, Antje -- Nusbaum, Chad -- Lander, Eric S -- Russ, Carsten -- Novod, Nathaniel -- Affourtit, Jason -- Egholm, Michael -- Verna, Christine -- Rudan, Pavao -- Brajkovic, Dejana -- Kucan, Zeljko -- Gusic, Ivan -- Doronichev, Vladimir B -- Golovanova, Liubov V -- Lalueza-Fox, Carles -- de la Rasilla, Marco -- Fortea, Javier -- Rosas, Antonio -- Schmitz, Ralf W -- Johnson, Philip L F -- Eichler, Evan E -- Falush, Daniel -- Birney, Ewan -- Mullikin, James C -- Slatkin, Montgomery -- Nielsen, Rasmus -- Kelso, Janet -- Lachmann, Michael -- Reich, David -- Paabo, Svante -- GM40282/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 May 7;328(5979):710-22. doi: 10.1126/science.1188021.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Evolutionary Genetics, Max-Planck Institute for Evolutionary Anthropology, D-04103 Leipzig, Germany. green@eva.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20448178" target="_blank"〉PubMed〈/a〉

    Rapid construction of empirical RNA fitness landscapes (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-10-16
    Description: Evolution is an adaptive walk through a hypothetical fitness landscape, which depicts the relationship between genotypes and the fitness of each corresponding phenotype. We constructed an empirical fitness landscape for a catalytic RNA by combining next-generation sequencing, computational analysis, and "serial depletion," an in vitro selection protocol. By determining the reaction rate constant for every point mutant of a catalytic RNA, we demonstrated that abundance in serially depleted pools correlates with biochemical activity (correlation coefficient r = 0.67, standard score Z = 7.4). Therefore, enumeration of each genotype by deep sequencing yielded a fitness landscape containing ~10(7) unique sequences, without requiring measurement of the phenotypic fitness for each sequence. High-throughput mapping between genotype and phenotype may apply to artificial selections, host-pathogen interactions, and other biomedically relevant evolutionary phenomena.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3392653/" 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/PMC3392653/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pitt, Jason N -- Ferre-D'Amare, Adrian R -- Z99 HL999999/Intramural NIH HHS/ -- ZIA HL006102-01/Intramural NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Oct 15;330(6002):376-9. doi: 10.1126/science.1192001.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Division of Basic Sciences, Fred Hutchinson Cancer Research Center, 1100 Fairview Avenue North, Seattle, WA 98109-1024, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20947767" target="_blank"〉PubMed〈/a〉

    Sequence- and structure-specific RNA processing by a CRISPR endonuclease (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-09-11
    Description: Many bacteria and archaea contain clustered regularly interspaced short palindromic repeats (CRISPRs) that confer resistance to invasive genetic elements. Central to this immune system is the production of CRISPR-derived RNAs (crRNAs) after transcription of the CRISPR locus. Here, we identify the endoribonuclease (Csy4) responsible for CRISPR transcript (pre-crRNA) processing in Pseudomonas aeruginosa. A 1.8 angstrom crystal structure of Csy4 bound to its cognate RNA reveals that Csy4 makes sequence-specific interactions in the major groove of the crRNA repeat stem-loop. Together with electrostatic contacts to the phosphate backbone, these enable Csy4 to bind selectively and cleave pre-crRNAs using phylogenetically conserved serine and histidine residues in the active site. The RNA recognition mechanism identified here explains sequence- and structure-specific processing by a large family of CRISPR-specific endoribonucleases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3133607/" 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/PMC3133607/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haurwitz, Rachel E -- Jinek, Martin -- Wiedenheft, Blake -- Zhou, Kaihong -- Doudna, Jennifer A -- 5 T32 GM08295/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Sep 10;329(5997):1355-8. doi: 10.1126/science.1192272.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, University of California, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20829488" target="_blank"〉PubMed〈/a〉

    CRISPR/Cas, the immune system of bacteria and archaea (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-09
    Description: Microbes rely on diverse defense mechanisms that allow them to withstand viral predation and exposure to invading nucleic acid. In many Bacteria and most Archaea, clustered regularly interspaced short palindromic repeats (CRISPR) form peculiar genetic loci, which provide acquired immunity against viruses and plasmids by targeting nucleic acid in a sequence-specific manner. These hypervariable loci take up genetic material from invasive elements and build up inheritable DNA-encoded immunity over time. Conversely, viruses have devised mutational escape strategies that allow them to circumvent the CRISPR/Cas system, albeit at a cost. CRISPR features may be exploited for typing purposes, epidemiological studies, host-virus ecological surveys, building specific immunity against undesirable genetic elements, and enhancing viral resistance in domesticated microbes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Horvath, Philippe -- Barrangou, Rodolphe -- New York, N.Y. -- Science. 2010 Jan 8;327(5962):167-70. doi: 10.1126/science.1179555.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Danisco France SAS, BP10, F-86220 Dange-Saint-Romain, France. philippe.horvath@danisco.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20056882" target="_blank"〉PubMed〈/a〉

    Horizontal gene transfer by the parasitic plant Striga hermonthica (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-05-29
    Description: Horizontal gene transfer has been postulated to occur between crops to co-occurring parasitic plants, but empirical evidence has been lacking. We present evidence that an HGT event moved a nuclear monocot gene into the genome of the eudicot parasite witchweed (Striga hermonthica), which infects many grass species in Africa. Analysis of expressed sequence tags revealed that the genome of S. hermonthica contains a nuclear gene that is widely conserved among grass species but is not found in other eudicots. Phylogenetically, this gene clusters with sorghum genes, the monocot host of the parasitic weed, suggesting that nuclear genes can be captured by parasitic weeds in nature.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoshida, Satoko -- Maruyama, Shinichiro -- Nozaki, Hisayoshi -- Shirasu, Ken -- New York, N.Y. -- Science. 2010 May 28;328(5982):1128. doi: 10.1126/science.1187145.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉RIKEN Plant Science Center, Tsurumi, Yokohama 230-0045, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20508124" target="_blank"〉PubMed〈/a〉

    Topology links RNA secondary structure with global conformation, dynamics, and adaptation (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-09
    Description: Thermodynamic rules that link RNA sequences to secondary structure are well established, but the link between secondary structure and three-dimensional global conformation remains poorly understood. We constructed comprehensive three-dimensional maps depicting the orientation of A-form helices across RNA junctions in the Protein Data Bank and rationalized our findings with modeling and nuclear magnetic resonance spectroscopy. We show that the secondary structures of junctions encode readily computable topological constraints that accurately predict the three-dimensional orientation of helices across all two-way junctions. Our results suggest that RNA global conformation is largely defined by topological constraints encoded at the secondary structural level and that tertiary contacts and intermolecular interactions serve to stabilize specific conformers within the topologically allowed ensemble.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bailor, Maximillian H -- Sun, Xiaoyan -- Al-Hashimi, Hashim M -- R01 AI066975-01/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 8;327(5962):202-6. doi: 10.1126/science.1181085.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biophysics, University of Michigan, Ann Arbor, MI 48109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20056889" target="_blank"〉PubMed〈/a〉

    Development of transgenic fungi that kill human malaria parasites in mosquitoes (2011)

    Details
    Publication Date: 2011-02-26
    Description: Metarhizium anisopliae infects mosquitoes through the cuticle and proliferates in the hemolymph. To allow M. anisopliae to combat malaria in mosquitoes with advanced malaria infections, we produced recombinant strains expressing molecules that target sporozoites as they travel through the hemolymph to the salivary glands. Eleven days after a Plasmodium-infected blood meal, mosquitoes were treated with M. anisopliae expressing salivary gland and midgut peptide 1 (SM1), which blocks attachment of sporozoites to salivary glands; a single-chain antibody that agglutinates sporozoites; or scorpine, which is an antimicrobial toxin. These reduced sporozoite counts by 71%, 85%, and 90%, respectively. M. anisopliae expressing scorpine and an [SM1](8):scorpine fusion protein reduced sporozoite counts by 98%, suggesting that Metarhizium-mediated inhibition of Plasmodium development could be a powerful weapon for combating malaria.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4153607/" 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/PMC4153607/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fang, Weiguo -- Vega-Rodriguez, Joel -- Ghosh, Anil K -- Jacobs-Lorena, Marcelo -- Kang, Angray -- St Leger, Raymond J -- 5R21A1079429-02/PHS HHS/ -- R01 AI031478/AI/NIAID NIH HHS/ -- R21 AI079429/AI/NIAID NIH HHS/ -- R21 AI088033/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2011 Feb 25;331(6020):1074-7. doi: 10.1126/science.1199115.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomology, University of Maryland, 4112 Plant Sciences Building, College Park, MD 20742, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21350178" target="_blank"〉PubMed〈/a〉

    Widespread RNA and DNA sequence differences in the human transcriptome (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-05-21
    Description: The transmission of information from DNA to RNA is a critical process. We compared RNA sequences from human B cells of 27 individuals to the corresponding DNA sequences from the same individuals and uncovered more than 10,000 exonic sites where the RNA sequences do not match that of the DNA. All 12 possible categories of discordances were observed. These differences were nonrandom as many sites were found in multiple individuals and in different cell types, including primary skin cells and brain tissues. Using mass spectrometry, we detected peptides that are translated from the discordant RNA sequences and thus do not correspond exactly to the DNA sequences. These widespread RNA-DNA differences in the human transcriptome provide a yet unexplored aspect of genome variation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3204392/" 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/PMC3204392/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Mingyao -- Wang, Isabel X -- Li, Yun -- Bruzel, Alan -- Richards, Allison L -- Toung, Jonathan M -- Cheung, Vivian G -- R01 HG005854/HG/NHGRI NIH HHS/ -- R01 HG005854-01/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Jul 1;333(6038):53-8. doi: 10.1126/science.1207018.

    DNA synthesis generates terminal duplications that seal end-to-end chromosome fusions (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-04-23
    Description: End-to-end chromosome fusions that occur in the context of telomerase deficiency can trigger genomic duplications. For more than 70 years, these duplications have been attributed solely to breakage-fusion-bridge cycles. To test this hypothesis, we examined end-to-end fusions isolated from Caenorhabditis elegans telomere replication mutants. Genome-level rearrangements revealed fused chromosome ends having interrupted terminal duplications accompanied by template-switching events. These features are very similar to disease-associated duplications of interstitial segments of the human genome. A model termed Fork Stalling and Template Switching has been proposed previously to explain such duplications, where promiscuous replication of large, noncontiguous segments of the genome occurs. Thus, a DNA synthesis-based process may create duplications that seal end-to-end fusions, in the absence of breakage-fusion-bridge cycles.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4154375/" 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/PMC4154375/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lowden, Mia Rochelle -- Flibotte, Stephane -- Moerman, Donald G -- Ahmed, Shawn -- GM066228/GM/NIGMS NIH HHS/ -- GM072150/GM/NIGMS NIH HHS/ -- R01 GM066228/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2011 Apr 22;332(6028):468-71. doi: 10.1126/science.1199022.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, University of North Carolina, Chapel Hill, NC 27599, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21512032" target="_blank"〉PubMed〈/a〉
