Description: Long interspersed nuclear element-1 (L1) retrotransposons are mobile repetitive elements that are abundant in the human genome. L1 elements propagate through RNA intermediates. In the germ line, neighboring, nonrepetitive sequences are occasionally mobilized by the L1 machinery, a process called 3' transduction. Because 3' transductions are potentially mutagenic, we explored the extent to which they occur somatically during tumorigenesis. Studying cancer genomes from 244 patients, we found that tumors from 53% of the patients had somatic retrotranspositions, of which 24% were 3' transductions. Fingerprinting of donor L1s revealed that a handful of source L1 elements in a tumor can spawn from tens to hundreds of 3' transductions, which can themselves seed further retrotranspositions. The activity of individual L1 elements fluctuated during tumor evolution and correlated with L1 promoter hypomethylation. The 3' transductions disseminated genes, exons, and regulatory elements to new locations, most often to heterochromatic regions of the genome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4380235/" 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/PMC4380235/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tubio, Jose M C -- Li, Yilong -- Ju, Young Seok -- Martincorena, Inigo -- Cooke, Susanna L -- Tojo, Marta -- Gundem, Gunes -- Pipinikas, Christodoulos P -- Zamora, Jorge -- Raine, Keiran -- Menzies, Andrew -- Roman-Garcia, Pablo -- Fullam, Anthony -- Gerstung, Moritz -- Shlien, Adam -- Tarpey, Patrick S -- Papaemmanuil, Elli -- Knappskog, Stian -- Van Loo, Peter -- Ramakrishna, Manasa -- Davies, Helen R -- Marshall, John -- Wedge, David C -- Teague, Jon W -- Butler, Adam P -- Nik-Zainal, Serena -- Alexandrov, Ludmil -- Behjati, Sam -- Yates, Lucy R -- Bolli, Niccolo -- Mudie, Laura -- Hardy, Claire -- Martin, Sancha -- McLaren, Stuart -- O'Meara, Sarah -- Anderson, Elizabeth -- Maddison, Mark -- Gamble, Stephen -- ICGC Breast Cancer Group -- ICGC Bone Cancer Group -- ICGC Prostate Cancer Group -- Foster, Christopher -- Warren, Anne Y -- Whitaker, Hayley -- Brewer, Daniel -- Eeles, Rosalind -- Cooper, Colin -- Neal, David -- Lynch, Andy G -- Visakorpi, Tapio -- Isaacs, William B -- van't Veer, Laura -- Caldas, Carlos -- Desmedt, Christine -- Sotiriou, Christos -- Aparicio, Sam -- Foekens, John A -- Eyfjord, Jorunn Erla -- Lakhani, Sunil R -- Thomas, Gilles -- Myklebost, Ola -- Span, Paul N -- Borresen-Dale, Anne-Lise -- Richardson, Andrea L -- Van de Vijver, Marc -- Vincent-Salomon, Anne -- Van den Eynden, Gert G -- Flanagan, Adrienne M -- Futreal, P Andrew -- Janes, Sam M -- Bova, G Steven -- Stratton, Michael R -- McDermott, Ultan -- Campbell, Peter J -- 088340/Wellcome Trust/United Kingdom -- 091730/Wellcome Trust/United Kingdom -- 14835/Cancer Research UK/United Kingdom -- C5047/A14835/Cancer Research UK/United Kingdom -- G0900871/Medical Research Council/United Kingdom -- P30 CA006973/CA/NCI NIH HHS/ -- WT100183MA/Wellcome Trust/United Kingdom -- Department of Health/United Kingdom -- New York, N.Y. -- Science. 2014 Aug 1;345(6196):1251343. doi: 10.1126/science.1251343.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Hinxton, Cambridgeshire, UK. ; Department of Physiology, School of Medicine-Center for Resesarch in Molecular Medicine and Chronic Diseases, Instituto de Investigaciones Sanitarias, University of Santiago de Compostela, Spain. ; Lungs for Living Research Centre, Rayne Institute, University College London (UCL), London, UK. ; Wellcome Trust Sanger Institute, Hinxton, Cambridgeshire, UK.
