Description:
Tapeworms (Cestoda) cause neglected diseases that can be fatal and are difficult to treat, owing to inefficient drugs. Here we present an analysis of tapeworm genome sequences using the human-infective species Echinococcus multilocularis, E. granulosus, Taenia solium and the laboratory model Hymenolepis microstoma as examples. The 115- to 141-megabase genomes offer insights into the evolution of parasitism. Synteny is maintained with distantly related blood flukes but we find extreme losses of genes and pathways that are ubiquitous in other animals, including 34 homeobox families and several determinants of stem cell fate. Tapeworms have specialized detoxification pathways, metabolism that is finely tuned to rely on nutrients scavenged from their hosts, and species-specific expansions of non-canonical heat shock proteins and families of known antigens. We identify new potential drug targets, including some on which existing pharmaceuticals may act. The genomes provide a rich resource to underpin the development of urgently needed treatments and control.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3964345/" 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/PMC3964345/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsai, Isheng J -- Zarowiecki, Magdalena -- Holroyd, Nancy -- Garciarrubio, Alejandro -- Sanchez-Flores, Alejandro -- Brooks, Karen L -- Tracey, Alan -- Bobes, Raul J -- Fragoso, Gladis -- Sciutto, Edda -- Aslett, Martin -- Beasley, Helen -- Bennett, Hayley M -- Cai, Jianping -- Camicia, Federico -- Clark, Richard -- Cucher, Marcela -- De Silva, Nishadi -- Day, Tim A -- Deplazes, Peter -- Estrada, Karel -- Fernandez, Cecilia -- Holland, Peter W H -- Hou, Junling -- Hu, Songnian -- Huckvale, Thomas -- Hung, Stacy S -- Kamenetzky, Laura -- Keane, Jacqueline A -- Kiss, Ferenc -- Koziol, Uriel -- Lambert, Olivia -- Liu, Kan -- Luo, Xuenong -- Luo, Yingfeng -- Macchiaroli, Natalia -- Nichol, Sarah -- Paps, Jordi -- Parkinson, John -- Pouchkina-Stantcheva, Natasha -- Riddiford, Nick -- Rosenzvit, Mara -- Salinas, Gustavo -- Wasmuth, James D -- Zamanian, Mostafa -- Zheng, Yadong -- Taenia solium Genome Consortium -- Cai, Xuepeng -- Soberon, Xavier -- Olson, Peter D -- Laclette, Juan P -- Brehm, Klaus -- Berriman, Matthew -- 085775/Wellcome Trust/United Kingdom -- 098051/Wellcome Trust/United Kingdom -- BBG0038151/Biotechnology and Biological Sciences Research Council/United Kingdom -- MOP#84556/Canadian Institutes of Health Research/Canada -- TW008588/TW/FIC NIH HHS/ -- England -- Nature. 2013 Apr 4;496(7443):57-63. doi: 10.1038/nature12031.
