    Recognition by human V gamma 9/V delta 2 T cells of a GroEL homolog on Daudi Burkitt's lymphoma cells (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-11-30
    Description: All human gamma delta T cells coexpressing the products of the variable (V) region T cell receptor (TCR) gene segments V gamma 9 and V delta 2 recognize antigens from mycobacterial extracts and Daudi cells. Exogenous and endogenous ligands on the cell surface, homologous to the groEL heat shock family, induced reactivities that resembled superantigen responses in this major subset of human peripheral blood gamma delta T cells. Stimulation of human V gamma 9/V delta 2 T cells is not restricted by human leukocyte antigens (HLA), including nonpolymorphic beta 2-microglobulin (beta 2M)-associated class Ib molecules. These data may be important for understanding the role of gamma delta T cells in autoimmunity and in responses to microorganisms and tumors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fisch, P -- Malkovsky, M -- Kovats, S -- Sturm, E -- Braakman, E -- Klein, B S -- Voss, S D -- Morrissey, L W -- DeMars, R -- Welch, W J -- New York, N.Y. -- Science. 1990 Nov 30;250(4985):1269-73.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Human Oncology, University of Wisconsin, Madison 53792.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1978758" target="_blank"〉PubMed〈/a〉

    Enhancer hijacking activates GFI1 family oncogenes in medulloblastoma (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-07-22
    Description: Medulloblastoma is a highly malignant paediatric brain tumour currently treated with a combination of surgery, radiation and chemotherapy, posing a considerable burden of toxicity to the developing child. Genomics has illuminated the extensive intertumoral heterogeneity of medulloblastoma, identifying four distinct molecular subgroups. Group 3 and group 4 subgroup medulloblastomas account for most paediatric cases; yet, oncogenic drivers for these subtypes remain largely unidentified. Here we describe a series of prevalent, highly disparate genomic structural variants, restricted to groups 3 and 4, resulting in specific and mutually exclusive activation of the growth factor independent 1 family proto-oncogenes, GFI1 and GFI1B. Somatic structural variants juxtapose GFI1 or GFI1B coding sequences proximal to active enhancer elements, including super-enhancers, instigating oncogenic activity. Our results, supported by evidence from mouse models, identify GFI1 and GFI1B as prominent medulloblastoma oncogenes and implicate 'enhancer hijacking' as an efficient mechanism driving oncogene activation in a childhood cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4201514/" 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/PMC4201514/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Northcott, Paul A -- Lee, Catherine -- Zichner, Thomas -- Stutz, Adrian M -- Erkek, Serap -- Kawauchi, Daisuke -- Shih, David J H -- Hovestadt, Volker -- Zapatka, Marc -- Sturm, Dominik -- Jones, David T W -- Kool, Marcel -- Remke, Marc -- Cavalli, Florence M G -- Zuyderduyn, Scott -- Bader, Gary D -- VandenBerg, Scott -- Esparza, Lourdes Adriana -- Ryzhova, Marina -- Wang, Wei -- Wittmann, Andrea -- Stark, Sebastian -- Sieber, Laura -- Seker-Cin, Huriye -- Linke, Linda -- Kratochwil, Fabian -- Jager, Natalie -- Buchhalter, Ivo -- Imbusch, Charles D -- Zipprich, Gideon -- Raeder, Benjamin -- Schmidt, Sabine -- Diessl, Nicolle -- Wolf, Stephan -- Wiemann, Stefan -- Brors, Benedikt -- Lawerenz, Chris -- Eils, Jurgen -- Warnatz, Hans-Jorg -- Risch, Thomas -- Yaspo, Marie-Laure -- Weber, Ursula D -- Bartholomae, Cynthia C -- von Kalle, Christof -- Turanyi, Eszter -- Hauser, Peter -- Sanden, Emma -- Darabi, Anna -- Siesjo, Peter -- Sterba, Jaroslav -- Zitterbart, Karel -- Sumerauer, David -- van Sluis, Peter -- Versteeg, Rogier -- Volckmann, Richard -- Koster, Jan -- Schuhmann, Martin U -- Ebinger, Martin -- Grimes, H Leighton -- Robinson, Giles W -- Gajjar, Amar -- Mynarek, Martin -- von Hoff, Katja -- Rutkowski, Stefan -- Pietsch, Torsten -- Scheurlen, Wolfram -- Felsberg, Jorg -- Reifenberger, Guido -- Kulozik, Andreas E -- von Deimling, Andreas -- Witt, Olaf -- Eils, Roland -- Gilbertson, Richard J -- Korshunov, Andrey -- Taylor, Michael D -- Lichter, Peter -- Korbel, Jan O -- Wechsler-Reya, Robert J -- Pfister, Stefan M -- 5P30CA030199/CA/NCI NIH HHS/ -- P01 CA096832/CA/NCI NIH HHS/ -- P30 CA030199/CA/NCI NIH HHS/ -- P41GM103504/GM/NIGMS NIH HHS/ -- R01 CA159859/CA/NCI NIH HHS/ -- England -- Nature. 2014 Jul 24;511(7510):428-34. doi: 10.1038/nature13379.

    Derived immune and ancestral pigmentation alleles in a 7,000-year-old Mesolithic European (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-01-28
    Description: Ancient genomic sequences have started to reveal the origin and the demographic impact of farmers from the Neolithic period spreading into Europe. The adoption of farming, stock breeding and sedentary societies during the Neolithic may have resulted in adaptive changes in genes associated with immunity and diet. However, the limited data available from earlier hunter-gatherers preclude an understanding of the selective processes associated with this crucial transition to agriculture in recent human evolution. Here we sequence an approximately 7,000-year-old Mesolithic skeleton discovered at the La Brana-Arintero site in Leon, Spain, to retrieve a complete pre-agricultural European human genome. Analysis of this genome in the context of other ancient samples suggests the existence of a common ancient genomic signature across western and central Eurasia from the Upper Paleolithic to the Mesolithic. The La Brana individual carries ancestral alleles in several skin pigmentation genes, suggesting that the light skin of modern Europeans was not yet ubiquitous in Mesolithic times. Moreover, we provide evidence that a significant number of derived, putatively adaptive variants associated with pathogen resistance in modern Europeans were already present in this hunter-gatherer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4269527/" 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/PMC4269527/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olalde, Inigo -- Allentoft, Morten E -- Sanchez-Quinto, Federico -- Santpere, Gabriel -- Chiang, Charleston W K -- DeGiorgio, Michael -- Prado-Martinez, Javier -- Rodriguez, Juan Antonio -- Rasmussen, Simon -- Quilez, Javier -- Ramirez, Oscar -- Marigorta, Urko M -- Fernandez-Callejo, Marcos -- Prada, Maria Encina -- Encinas, Julio Manuel Vidal -- Nielsen, Rasmus -- Netea, Mihai G -- Novembre, John -- Sturm, Richard A -- Sabeti, Pardis -- Marques-Bonet, Tomas -- Navarro, Arcadi -- Willerslev, Eske -- Lalueza-Fox, Carles -- F32 GM106656/GM/NIGMS NIH HHS/ -- F32GM106656/GM/NIGMS NIH HHS/ -- R01 HG007089/HG/NHGRI NIH HHS/ -- R01-HG007089/HG/NHGRI NIH HHS/ -- England -- Nature. 2014 Mar 13;507(7491):225-8. doi: 10.1038/nature12960.

    Dissecting the genomic complexity underlying medulloblastoma (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-07-27
    Description: Medulloblastoma is an aggressively growing tumour, arising in the cerebellum or medulla/brain stem. It is the most common malignant brain tumour in children, and shows tremendous biological and clinical heterogeneity. Despite recent treatment advances, approximately 40% of children experience tumour recurrence, and 30% will die from their disease. Those who survive often have a significantly reduced quality of life. Four tumour subgroups with distinct clinical, biological and genetic profiles are currently identified. WNT tumours, showing activated wingless pathway signalling, carry a favourable prognosis under current treatment regimens. SHH tumours show hedgehog pathway activation, and have an intermediate prognosis. Group 3 and 4 tumours are molecularly less well characterized, and also present the greatest clinical challenges. The full repertoire of genetic events driving this distinction, however, remains unclear. Here we describe an integrative deep-sequencing analysis of 125 tumour-normal pairs, conducted as part of the International Cancer Genome Consortium (ICGC) PedBrain Tumor Project. Tetraploidy was identified as a frequent early event in Group 3 and 4 tumours, and a positive correlation between patient age and mutation rate was observed. Several recurrent mutations were identified, both in known medulloblastoma-related genes (CTNNB1, PTCH1, MLL2, SMARCA4) and in genes not previously linked to this tumour (DDX3X, CTDNEP1, KDM6A, TBR1), often in subgroup-specific patterns. RNA sequencing confirmed these alterations, and revealed the expression of what are, to our knowledge, the first medulloblastoma fusion genes identified. Chromatin modifiers were frequently altered across all subgroups. These findings enhance our understanding of the genomic complexity and heterogeneity underlying medulloblastoma, and provide several potential targets for new therapeutics, especially for Group 3 and 4 patients.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3662966/" 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/PMC3662966/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jones, David T W -- Jager, Natalie -- Kool, Marcel -- Zichner, Thomas -- Hutter, Barbara -- Sultan, Marc -- Cho, Yoon-Jae -- Pugh, Trevor J -- Hovestadt, Volker -- Stutz, Adrian M -- Rausch, Tobias -- Warnatz, Hans-Jorg -- Ryzhova, Marina -- Bender, Sebastian -- Sturm, Dominik -- Pleier, Sabrina -- Cin, Huriye -- Pfaff, Elke -- Sieber, Laura -- Wittmann, Andrea -- Remke, Marc -- Witt, Hendrik -- Hutter, Sonja -- Tzaridis, Theophilos -- Weischenfeldt, Joachim -- Raeder, Benjamin -- Avci, Meryem -- Amstislavskiy, Vyacheslav -- Zapatka, Marc -- Weber, Ursula D -- Wang, Qi -- Lasitschka, Barbel -- Bartholomae, Cynthia C -- Schmidt, Manfred -- von Kalle, Christof -- Ast, Volker -- Lawerenz, Chris -- Eils, Jurgen -- Kabbe, Rolf -- Benes, Vladimir -- van Sluis, Peter -- Koster, Jan -- Volckmann, Richard -- Shih, David -- Betts, Matthew J -- Russell, Robert B -- Coco, Simona -- Tonini, Gian Paolo -- Schuller, Ulrich -- Hans, Volkmar -- Graf, Norbert -- Kim, Yoo-Jin -- Monoranu, Camelia -- Roggendorf, Wolfgang -- Unterberg, Andreas -- Herold-Mende, Christel -- Milde, Till -- Kulozik, Andreas E -- von Deimling, Andreas -- Witt, Olaf -- Maass, Eberhard -- Rossler, Jochen -- Ebinger, Martin -- Schuhmann, Martin U -- Fruhwald, Michael C -- Hasselblatt, Martin -- Jabado, Nada -- Rutkowski, Stefan -- von Bueren, Andre O -- Williamson, Dan -- Clifford, Steven C -- McCabe, Martin G -- Collins, V Peter -- Wolf, Stephan -- Wiemann, Stefan -- Lehrach, Hans -- Brors, Benedikt -- Scheurlen, Wolfram -- Felsberg, Jorg -- Reifenberger, Guido -- Northcott, Paul A -- Taylor, Michael D -- Meyerson, Matthew -- Pomeroy, Scott L -- Yaspo, Marie-Laure -- Korbel, Jan O -- Korshunov, Andrey -- Eils, Roland -- Pfister, Stefan M -- Lichter, Peter -- P30 HD018655/HD/NICHD NIH HHS/ -- R01 CA109467/CA/NCI NIH HHS/ -- England -- Nature. 2012 Aug 2;488(7409):100-5. doi: 10.1038/nature11284.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Pediatric Neurooncology, German Cancer Research Center (DKFZ), Im Neuenheimer Feld 280, Heidelberg 69120, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22832583" target="_blank"〉PubMed〈/a〉

    Driver mutations in histone H3.3 and chromatin remodelling genes in paediatric glioblastoma (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-01-31
    Description: Glioblastoma multiforme (GBM) is a lethal brain tumour in adults and children. However, DNA copy number and gene expression signatures indicate differences between adult and paediatric cases. To explore the genetic events underlying this distinction, we sequenced the exomes of 48 paediatric GBM samples. Somatic mutations in the H3.3-ATRX-DAXX chromatin remodelling pathway were identified in 44% of tumours (21/48). Recurrent mutations in H3F3A, which encodes the replication-independent histone 3 variant H3.3, were observed in 31% of tumours, and led to amino acid substitutions at two critical positions within the histone tail (K27M, G34R/G34V) involved in key regulatory post-translational modifications. Mutations in ATRX (alpha-thalassaemia/mental retardation syndrome X-linked) and DAXX (death-domain associated protein), encoding two subunits of a chromatin remodelling complex required for H3.3 incorporation at pericentric heterochromatin and telomeres, were identified in 31% of samples overall, and in 100% of tumours harbouring a G34R or G34V H3.3 mutation. Somatic TP53 mutations were identified in 54% of all cases, and in 86% of samples with H3F3A and/or ATRX mutations. Screening of a large cohort of gliomas of various grades and histologies (n = 784) showed H3F3A mutations to be specific to GBM and highly prevalent in children and young adults. Furthermore, the presence of H3F3A/ATRX-DAXX/TP53 mutations was strongly associated with alternative lengthening of telomeres and specific gene expression profiles. This is, to our knowledge, the first report to highlight recurrent mutations in a regulatory histone in humans, and our data suggest that defects of the chromatin architecture underlie paediatric and young adult GBM pathogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schwartzentruber, Jeremy -- Korshunov, Andrey -- Liu, Xiao-Yang -- Jones, David T W -- Pfaff, Elke -- Jacob, Karine -- Sturm, Dominik -- Fontebasso, Adam M -- Quang, Dong-Anh Khuong -- Tonjes, Martje -- Hovestadt, Volker -- Albrecht, Steffen -- Kool, Marcel -- Nantel, Andre -- Konermann, Carolin -- Lindroth, Anders -- Jager, Natalie -- Rausch, Tobias -- Ryzhova, Marina -- Korbel, Jan O -- Hielscher, Thomas -- Hauser, Peter -- Garami, Miklos -- Klekner, Almos -- Bognar, Laszlo -- Ebinger, Martin -- Schuhmann, Martin U -- Scheurlen, Wolfram -- Pekrun, Arnulf -- Fruhwald, Michael C -- Roggendorf, Wolfgang -- Kramm, Christoph -- Durken, Matthias -- Atkinson, Jeffrey -- Lepage, Pierre -- Montpetit, Alexandre -- Zakrzewska, Magdalena -- Zakrzewski, Krzystof -- Liberski, Pawel P -- Dong, Zhifeng -- Siegel, Peter -- Kulozik, Andreas E -- Zapatka, Marc -- Guha, Abhijit -- Malkin, David -- Felsberg, Jorg -- Reifenberger, Guido -- von Deimling, Andreas -- Ichimura, Koichi -- Collins, V Peter -- Witt, Hendrik -- Milde, Till -- Witt, Olaf -- Zhang, Cindy -- Castelo-Branco, Pedro -- Lichter, Peter -- Faury, Damien -- Tabori, Uri -- Plass, Christoph -- Majewski, Jacek -- Pfister, Stefan M -- Jabado, Nada -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2012 Jan 29;482(7384):226-31. doi: 10.1038/nature10833.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉McGill University and Genome Quebec Innovation Centre, Montreal, Quebec H3A 1A4, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22286061" target="_blank"〉PubMed〈/a〉

    Manipulation of host hepatocytes by the malaria parasite for delivery into liver sinusoids (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-05
    Description: The merozoite stage of the malaria parasite that infects erythrocytes and causes the symptoms of the disease is initially formed inside host hepatocytes. However, the mechanism by which hepatic merozoites reach blood vessels (sinusoids) in the liver and escape the host immune system before invading erythrocytes remains unknown. Here, we show that parasites induce the death and the detachment of their host hepatocytes, followed by the budding of parasite-filled vesicles (merosomes) into the sinusoid lumen. Parasites simultaneously inhibit the exposure of phosphatidylserine on the outer leaflet of host plasma membranes, which act as "eat me" signals to phagocytes. Thus, the hepatocyte-derived merosomes appear to ensure both the migration of parasites into the bloodstream and their protection from host immunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sturm, Angelika -- Amino, Rogerio -- van de Sand, Claudia -- Regen, Tommy -- Retzlaff, Silke -- Rennenberg, Annika -- Krueger, Andreas -- Pollok, Jorg-Matthias -- Menard, Robert -- Heussler, Volker T -- New York, N.Y. -- Science. 2006 Sep 1;313(5791):1287-90.

    Parasites resistant to the antimalarial atovaquone fail to transmit by mosquitoes (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-04-16
    Description: Drug resistance compromises control of malaria. Here, we show that resistance to a commonly used antimalarial medication, atovaquone, is apparently unable to spread. Atovaquone pressure selects parasites with mutations in cytochrome b, a respiratory protein with low but essential activity in the mammalian blood phase of the parasite life cycle. Resistance mutations rescue parasites from the drug but later prove lethal in the mosquito phase, where parasites require full respiration. Unable to respire efficiently, resistant parasites fail to complete mosquito development, arresting their life cycle. Because cytochrome b is encoded by the maternally inherited parasite mitochondrion, even outcrossing with wild-type strains cannot facilitate spread of resistance. Lack of transmission suggests that resistance will be unable to spread in the field, greatly enhancing the utility of atovaquone in malaria control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goodman, Christopher D -- Siregar, Josephine E -- Mollard, Vanessa -- Vega-Rodriguez, Joel -- Syafruddin, Din -- Matsuoka, Hiroyuki -- Matsuzaki, Motomichi -- Toyama, Tomoko -- Sturm, Angelika -- Cozijnsen, Anton -- Jacobs-Lorena, Marcelo -- Kita, Kiyoshi -- Marzuki, Sangkot -- McFadden, Geoffrey I -- AI031478/AI/NIAID NIH HHS/ -- RR00052/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 15;352(6283):349-53. doi: 10.1126/science.aad9279.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of BioSciences, University of Melbourne, Melbourne, VIC 3010, Australia. gim@unimelb.edu.au deang@unimelb.edu.au. ; School of BioSciences, University of Melbourne, Melbourne, VIC 3010, Australia.
