    Description: Schistosoma mansoni is responsible for the neglected tropical disease schistosomiasis that affects 210 million people in 76 countries. Here we present analysis of the 363 megabase nuclear genome of the blood fluke. It encodes at least 11,809 genes, with an unusual intron size distribution, and new families of micro-exon genes that undergo frequent alternative splicing. As the first sequenced flatworm, and a representative of the Lophotrochozoa, it offers insights into early events in the evolution of the animals, including the development of a body pattern with bilateral symmetry, and the development of tissues into organs. Our analysis has been informed by the need to find new drug targets. The deficits in lipid metabolism that make schistosomes dependent on the host are revealed, and the identification of membrane receptors, ion channels and more than 300 proteases provide new insights into the biology of the life cycle and new targets. Bioinformatics approaches have identified metabolic chokepoints, and a chemogenomic screen has pinpointed schistosome proteins for which existing drugs may be active. The information generated provides an invaluable resource for the research community to develop much needed new control tools for the treatment and eradication of this important and neglected disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2756445/" 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/PMC2756445/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berriman, Matthew -- Haas, Brian J -- LoVerde, Philip T -- Wilson, R Alan -- Dillon, Gary P -- Cerqueira, Gustavo C -- Mashiyama, Susan T -- Al-Lazikani, Bissan -- Andrade, Luiza F -- Ashton, Peter D -- Aslett, Martin A -- Bartholomeu, Daniella C -- Blandin, Gaelle -- Caffrey, Conor R -- Coghlan, Avril -- Coulson, Richard -- Day, Tim A -- Delcher, Art -- DeMarco, Ricardo -- Djikeng, Appolinaire -- Eyre, Tina -- Gamble, John A -- Ghedin, Elodie -- Gu, Yong -- Hertz-Fowler, Christiane -- Hirai, Hirohisha -- Hirai, Yuriko -- Houston, Robin -- Ivens, Alasdair -- Johnston, David A -- Lacerda, Daniela -- Macedo, Camila D -- McVeigh, Paul -- Ning, Zemin -- Oliveira, Guilherme -- Overington, John P -- Parkhill, Julian -- Pertea, Mihaela -- Pierce, Raymond J -- Protasio, Anna V -- Quail, Michael A -- Rajandream, Marie-Adele -- Rogers, Jane -- Sajid, Mohammed -- Salzberg, Steven L -- Stanke, Mario -- Tivey, Adrian R -- White, Owen -- Williams, David L -- Wortman, Jennifer -- Wu, Wenjie -- Zamanian, Mostafa -- Zerlotini, Adhemar -- Fraser-Liggett, Claire M -- Barrell, Barclay G -- El-Sayed, Najib M -- 086151/Wellcome Trust/United Kingdom -- 5D43TW006580/TW/FIC NIH HHS/ -- 5D43TW007012-03/TW/FIC NIH HHS/ -- AI054711-01A2/AI/NIAID NIH HHS/ -- AI48828/AI/NIAID NIH HHS/ -- R01 GM083873/GM/NIGMS NIH HHS/ -- R01 GM083873-07/GM/NIGMS NIH HHS/ -- R01 GM083873-08/GM/NIGMS NIH HHS/ -- R01 LM006845/LM/NLM NIH HHS/ -- R01 LM006845-08/LM/NLM NIH HHS/ -- R01 LM006845-09/LM/NLM NIH HHS/ -- U01 AI048828/AI/NIAID NIH HHS/ -- U01 AI048828-01/AI/NIAID NIH HHS/ -- U01 AI048828-02/AI/NIAID NIH HHS/ -- WT085775/Z/08/Z/Wellcome Trust/United Kingdom -- England -- Nature. 2009 Jul 16;460(7253):352-8. doi: 10.1038/nature08160.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Cambridge CB10 1SD, UK. mb4@sanger.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19606141" target="_blank"〉PubMed〈/a〉

    Description: Whole-genome sequencing of the protozoan pathogen Trypanosoma cruzi revealed that the diploid genome contains a predicted 22,570 proteins encoded by genes, of which 12,570 represent allelic pairs. Over 50% of the genome consists of repeated sequences, such as retrotransposons and genes for large families of surface molecules, which include trans-sialidases, mucins, gp63s, and a large novel family (〉1300 copies) of mucin-associated surface protein (MASP) genes. Analyses of the T. cruzi, T. brucei, and Leishmania major (Tritryp) genomes imply differences from other eukaryotes in DNA repair and initiation of replication and reflect their unusual mitochondrial DNA. Although the Tritryp lack several classes of signaling molecules, their kinomes contain a large and diverse set of protein kinases and phosphatases; their size and diversity imply previously unknown interactions and regulatory processes, which may be targets for intervention.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉El-Sayed, Najib M -- Myler, Peter J -- Bartholomeu, Daniella C -- Nilsson, Daniel -- Aggarwal, Gautam -- Tran, Anh-Nhi -- Ghedin, Elodie -- Worthey, Elizabeth A -- Delcher, Arthur L -- Blandin, Gaelle -- Westenberger, Scott J -- Caler, Elisabet -- Cerqueira, Gustavo C -- Branche, Carole -- Haas, Brian -- Anupama, Atashi -- Arner, Erik -- Aslund, Lena -- Attipoe, Philip -- Bontempi, Esteban -- Bringaud, Frederic -- Burton, Peter -- Cadag, Eithon -- Campbell, David A -- Carrington, Mark -- Crabtree, Jonathan -- Darban, Hamid -- da Silveira, Jose Franco -- de Jong, Pieter -- Edwards, Kimberly -- Englund, Paul T -- Fazelina, Gholam -- Feldblyum, Tamara -- Ferella, Marcela -- Frasch, Alberto Carlos -- Gull, Keith -- Horn, David -- Hou, Lihua -- Huang, Yiting -- Kindlund, Ellen -- Klingbeil, Michele -- Kluge, Sindy -- Koo, Hean -- Lacerda, Daniela -- Levin, Mariano J -- Lorenzi, Hernan -- Louie, Tin -- Machado, Carlos Renato -- McCulloch, Richard -- McKenna, Alan -- Mizuno, Yumi -- Mottram, Jeremy C -- Nelson, Siri -- Ochaya, Stephen -- Osoegawa, Kazutoyo -- Pai, Grace -- Parsons, Marilyn -- Pentony, Martin -- Pettersson, Ulf -- Pop, Mihai -- Ramirez, Jose Luis -- Rinta, Joel -- Robertson, Laura -- Salzberg, Steven L -- Sanchez, Daniel O -- Seyler, Amber -- Sharma, Reuben -- Shetty, Jyoti -- Simpson, Anjana J -- Sisk, Ellen -- Tammi, Martti T -- Tarleton, Rick -- Teixeira, Santuza -- Van Aken, Susan -- Vogt, Christy -- Ward, Pauline N -- Wickstead, Bill -- Wortman, Jennifer -- White, Owen -- Fraser, Claire M -- Stuart, Kenneth D -- Andersson, Bjorn -- AI045039/AI/NIAID NIH HHS/ -- AI45038/AI/NIAID NIH HHS/ -- AI45061/AI/NIAID NIH HHS/ -- R01 AI031077/AI/NIAID NIH HHS/ -- R01 AI031077-11/AI/NIAID NIH HHS/ -- U01 AI045038/AI/NIAID NIH HHS/ -- U01 AI045039/AI/NIAID NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2005 Jul 15;309(5733):409-15.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Parasite Genomics, Institute for Genomic Research, Rockville, MD 20850, USA. nelsayed@tigr.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16020725" target="_blank"〉PubMed〈/a〉

    Description: A comparison of gene content and genome architecture of Trypanosoma brucei, Trypanosoma cruzi, and Leishmania major, three related pathogens with different life cycles and disease pathology, revealed a conserved core proteome of about 6200 genes in large syntenic polycistronic gene clusters. Many species-specific genes, especially large surface antigen families, occur at nonsyntenic chromosome-internal and subtelomeric regions. Retroelements, structural RNAs, and gene family expansion are often associated with syntenic discontinuities that-along with gene divergence, acquisition and loss, and rearrangement within the syntenic regions-have shaped the genomes of each parasite. Contrary to recent reports, our analyses reveal no evidence that these species are descended from an ancestor that contained a photosynthetic endosymbiont.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉El-Sayed, Najib M -- Myler, Peter J -- Blandin, Gaelle -- Berriman, Matthew -- Crabtree, Jonathan -- Aggarwal, Gautam -- Caler, Elisabet -- Renauld, Hubert -- Worthey, Elizabeth A -- Hertz-Fowler, Christiane -- Ghedin, Elodie -- Peacock, Christopher -- Bartholomeu, Daniella C -- Haas, Brian J -- Tran, Anh-Nhi -- Wortman, Jennifer R -- Alsmark, U Cecilia M -- Angiuoli, Samuel -- Anupama, Atashi -- Badger, Jonathan -- Bringaud, Frederic -- Cadag, Eithon -- Carlton, Jane M -- Cerqueira, Gustavo C -- Creasy, Todd -- Delcher, Arthur L -- Djikeng, Appolinaire -- Embley, T Martin -- Hauser, Christopher -- Ivens, Alasdair C -- Kummerfeld, Sarah K -- Pereira-Leal, Jose B -- Nilsson, Daniel -- Peterson, Jeremy -- Salzberg, Steven L -- Shallom, Joshua -- Silva, Joana C -- Sundaram, Jaideep -- Westenberger, Scott -- White, Owen -- Melville, Sara E -- Donelson, John E -- Andersson, Bjorn -- Stuart, Kenneth D -- Hall, Neil -- AI045039/AI/NIAID NIH HHS/ -- AI45038/AI/NIAID NIH HHS/ -- AI45061/AI/NIAID NIH HHS/ -- R01 AI043062/AI/NIAID NIH HHS/ -- U01 AI040599/AI/NIAID NIH HHS/ -- U01 AI043062/AI/NIAID NIH HHS/ -- U01 AI045038/AI/NIAID NIH HHS/ -- U01 AI045039/AI/NIAID NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2005 Jul 15;309(5733):404-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Genomic Research, 9712 Medical Center Drive, Rockville, MD 20850, USA. nelsayed@tigr.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16020724" target="_blank"〉PubMed〈/a〉

    Description: African trypanosomes cause human sleeping sickness and livestock trypanosomiasis in sub-Saharan Africa. We present the sequence and analysis of the 11 megabase-sized chromosomes of Trypanosoma brucei. The 26-megabase genome contains 9068 predicted genes, including approximately 900 pseudogenes and approximately 1700 T. brucei-specific genes. Large subtelomeric arrays contain an archive of 806 variant surface glycoprotein (VSG) genes used by the parasite to evade the mammalian immune system. Most VSG genes are pseudogenes, which may be used to generate expressed mosaic genes by ectopic recombination. Comparisons of the cytoskeleton and endocytic trafficking systems with those of humans and other eukaryotic organisms reveal major differences. A comparison of metabolic pathways encoded by the genomes of T. brucei, T. cruzi, and Leishmania major reveals the least overall metabolic capability in T. brucei and the greatest in L. major. Horizontal transfer of genes of bacterial origin has contributed to some of the metabolic differences in these parasites, and a number of novel potential drug targets have been identified.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berriman, Matthew -- Ghedin, Elodie -- Hertz-Fowler, Christiane -- Blandin, Gaelle -- Renauld, Hubert -- Bartholomeu, Daniella C -- Lennard, Nicola J -- Caler, Elisabet -- Hamlin, Nancy E -- Haas, Brian -- Bohme, Ulrike -- Hannick, Linda -- Aslett, Martin A -- Shallom, Joshua -- Marcello, Lucio -- Hou, Lihua -- Wickstead, Bill -- Alsmark, U Cecilia M -- Arrowsmith, Claire -- Atkin, Rebecca J -- Barron, Andrew J -- Bringaud, Frederic -- Brooks, Karen -- Carrington, Mark -- Cherevach, Inna -- Chillingworth, Tracey-Jane -- Churcher, Carol -- Clark, Louise N -- Corton, Craig H -- Cronin, Ann -- Davies, Rob M -- Doggett, Jonathon -- Djikeng, Appolinaire -- Feldblyum, Tamara -- Field, Mark C -- Fraser, Audrey -- Goodhead, Ian -- Hance, Zahra -- Harper, David -- Harris, Barbara R -- Hauser, Heidi -- Hostetler, Jessica -- Ivens, Al -- Jagels, Kay -- Johnson, David -- Johnson, Justin -- Jones, Kristine -- Kerhornou, Arnaud X -- Koo, Hean -- Larke, Natasha -- Landfear, Scott -- Larkin, Christopher -- Leech, Vanessa -- Line, Alexandra -- Lord, Angela -- Macleod, Annette -- Mooney, Paul J -- Moule, Sharon -- Martin, David M A -- Morgan, Gareth W -- Mungall, Karen -- Norbertczak, Halina -- Ormond, Doug -- Pai, Grace -- Peacock, Chris S -- Peterson, Jeremy -- Quail, Michael A -- Rabbinowitsch, Ester -- Rajandream, Marie-Adele -- Reitter, Chris -- Salzberg, Steven L -- Sanders, Mandy -- Schobel, Seth -- Sharp, Sarah -- Simmonds, Mark -- Simpson, Anjana J -- Tallon, Luke -- Turner, C Michael R -- Tait, Andrew -- Tivey, Adrian R -- Van Aken, Susan -- Walker, Danielle -- Wanless, David -- Wang, Shiliang -- White, Brian -- White, Owen -- Whitehead, Sally -- Woodward, John -- Wortman, Jennifer -- Adams, Mark D -- Embley, T Martin -- Gull, Keith -- Ullu, Elisabetta -- Barry, J David -- Fairlamb, Alan H -- Opperdoes, Fred -- Barrell, Barclay G -- Donelson, John E -- Hall, Neil -- Fraser, Claire M -- Melville, Sara E -- El-Sayed, Najib M -- AI43062/AI/NIAID NIH HHS/ -- R01 AI043062/AI/NIAID NIH HHS/ -- U01 AI043062/AI/NIAID NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2005 Jul 15;309(5733):416-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton CB10 1SA, UK. mb4@sanger.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16020726" target="_blank"〉PubMed〈/a〉
