    MHC class II transactivator CIITA is a recurrent gene fusion partner in lymphoid cancers (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-03-04
    Description: Chromosomal translocations are critically involved in the molecular pathogenesis of B-cell lymphomas, and highly recurrent and specific rearrangements have defined distinct molecular subtypes linked to unique clinicopathological features. In contrast, several well-characterized lymphoma entities still lack disease-defining translocation events. To identify novel fusion transcripts resulting from translocations, we investigated two Hodgkin lymphoma cell lines by whole-transcriptome paired-end sequencing (RNA-seq). Here we show a highly expressed gene fusion involving the major histocompatibility complex (MHC) class II transactivator CIITA (MHC2TA) in KM-H2 cells. In a subsequent evaluation of 263 B-cell lymphomas, we also demonstrate that genomic CIITA breaks are highly recurrent in primary mediastinal B-cell lymphoma (38%) and classical Hodgkin lymphoma (cHL) (15%). Furthermore, we find that CIITA is a promiscuous partner of various in-frame gene fusions, and we report that CIITA gene alterations impact survival in primary mediastinal B-cell lymphoma (PMBCL). As functional consequences of CIITA gene fusions, we identify downregulation of surface HLA class II expression and overexpression of ligands of the receptor molecule programmed cell death 1 (CD274/PDL1 and CD273/PDL2). These receptor-ligand interactions have been shown to impact anti-tumour immune responses in several cancers, whereas decreased MHC class II expression has been linked to reduced tumour cell immunogenicity. Thus, our findings suggest that recurrent rearrangements of CIITA may represent a novel genetic mechanism underlying tumour-microenvironment interactions across a spectrum of lymphoid cancers.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3902849/" 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/PMC3902849/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Steidl, Christian -- Shah, Sohrab P -- Woolcock, Bruce W -- Rui, Lixin -- Kawahara, Masahiro -- Farinha, Pedro -- Johnson, Nathalie A -- Zhao, Yongjun -- Telenius, Adele -- Neriah, Susana Ben -- McPherson, Andrew -- Meissner, Barbara -- Okoye, Ujunwa C -- Diepstra, Arjan -- van den Berg, Anke -- Sun, Mark -- Leung, Gillian -- Jones, Steven J -- Connors, Joseph M -- Huntsman, David G -- Savage, Kerry J -- Rimsza, Lisa M -- Horsman, Douglas E -- Staudt, Louis M -- Steidl, Ulrich -- Marra, Marco A -- Gascoyne, Randy D -- 178536/Canadian Institutes of Health Research/Canada -- R00 CA131503/CA/NCI NIH HHS/ -- R00CA131503/CA/NCI NIH HHS/ -- T32 GM007288/GM/NIGMS NIH HHS/ -- England -- Nature. 2011 Mar 17;471(7338):377-81. doi: 10.1038/nature09754.

    Frequent mutation of histone-modifying genes in non-Hodgkin lymphoma (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-07-29
    Description: Follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL) are the two most common non-Hodgkin lymphomas (NHLs). Here we sequenced tumour and matched normal DNA from 13 DLBCL cases and one FL case to identify genes with mutations in B-cell NHL. We analysed RNA-seq data from these and another 113 NHLs to identify genes with candidate mutations, and then re-sequenced tumour and matched normal DNA from these cases to confirm 109 genes with multiple somatic mutations. Genes with roles in histone modification were frequent targets of somatic mutation. For example, 32% of DLBCL and 89% of FL cases had somatic mutations in MLL2, which encodes a histone methyltransferase, and 11.4% and 13.4% of DLBCL and FL cases, respectively, had mutations in MEF2B, a calcium-regulated gene that cooperates with CREBBP and EP300 in acetylating histones. Our analysis suggests a previously unappreciated disruption of chromatin biology in lymphomagenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3210554/" 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/PMC3210554/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morin, Ryan D -- Mendez-Lago, Maria -- Mungall, Andrew J -- Goya, Rodrigo -- Mungall, Karen L -- Corbett, Richard D -- Johnson, Nathalie A -- Severson, Tesa M -- Chiu, Readman -- Field, Matthew -- Jackman, Shaun -- Krzywinski, Martin -- Scott, David W -- Trinh, Diane L -- Tamura-Wells, Jessica -- Li, Sa -- Firme, Marlo R -- Rogic, Sanja -- Griffith, Malachi -- Chan, Susanna -- Yakovenko, Oleksandr -- Meyer, Irmtraud M -- Zhao, Eric Y -- Smailus, Duane -- Moksa, Michelle -- Chittaranjan, Suganthi -- Rimsza, Lisa -- Brooks-Wilson, Angela -- Spinelli, John J -- Ben-Neriah, Susana -- Meissner, Barbara -- Woolcock, Bruce -- Boyle, Merrill -- McDonald, Helen -- Tam, Angela -- Zhao, Yongjun -- Delaney, Allen -- Zeng, Thomas -- Tse, Kane -- Butterfield, Yaron -- Birol, Inanc -- Holt, Rob -- Schein, Jacqueline -- Horsman, Douglas E -- Moore, Richard -- Jones, Steven J M -- Connors, Joseph M -- Hirst, Martin -- Gascoyne, Randy D -- Marra, Marco A -- 1U01CA114778/CA/NCI NIH HHS/ -- HHSN261200800001E/PHS HHS/ -- P50CA130805-01/CA/NCI NIH HHS/ -- TGT-53912/Canadian Institutes of Health Research/Canada -- U24 CA143866/CA/NCI NIH HHS/ -- U24 CA143866-01/CA/NCI NIH HHS/ -- U24 CA143866-02/CA/NCI NIH HHS/ -- U24 CA143866-03/CA/NCI NIH HHS/ -- England -- Nature. 2011 Jul 27;476(7360):298-303. doi: 10.1038/nature10351.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Canada's Michael Smith Genome Sciences Centre, BC Cancer Agency, Vancouver, British Columbia V5Z 1L3, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21796119" target="_blank"〉PubMed〈/a〉

    Topics: Geography
    Notes: Abstract It is the aim of the author to show the general geo-scientific audience how they can profit from the specific view of cartographers when using remote sensing data. Leading from the explanation of cartography's tasks and the technically unique cartographic view on remote sensing data, it links up to the cartographic use of the data material. The author describes the direct and indirect applications with regard to topographic and thematic maps and reports from various practical projects in order to illustrate the main points. Finally the future dimension of remote sensing cartography within the field of developing geographical information systems (GIS) is pointed out.

    Notes: A theory of bound rubber formation has been developed which treats the effect as random adsorption of structural units of polymer on reactive sites which are assumed to exist on the surface of filler particles. Equations are derived for the fraction of bound rubber and for the molecular weight distribution of free (unbound) rubber. The theory contains only one adjustable parameter, the filler surface area per reactive site, A0. It is shown for the case of the Schulz distribution that the amount of bound rubber depends but slightly on the dispersion parameter of the polymer and is determined essentially by the adsorption index M̄w cP/A0NA, where c is the filler concentration, P is its specific surface area, and NA is the Avogadro number. All of the experimentally observed features of the bound rubber effect, including preferential adsorption of large molecules, are correctly predicted, the quantitative agreement of the theoretical equations with available experimental data being satisfatory. This supports the underlying assumption that the processes involved in the polymer-filler interaction may be approximated by a random-process model.

    Notes: Experimental data were obtained on the concentration dependence of the fraction of total filler-bound polymer, fraction of polymer in a coherent polymer-filler gel, and fraction of solvent-dispersed filler particles in compounds of fume silica (Aerosil OX50) with natural rubber (NR) and styrene butadiene rubber (SBR). Predictions of the polymer-filler gel formation theory were tested and a good formal description of the data was obtained. The two adjustable parameters of the theory assume reasonable values. While A0 is a characteristic of the filler interaction with polymer and has similar values in NR and SBR, the functionality f of the theoretically assumed filler particle acting as a polyfunctional crosslinker of polymer chains seems to depend on the polymer as well. Dimensions of the theoretical filler particle calculated from a comparison of experiment with theory are of the same order of magnitude but smaller than those of primary filler particles. © 1994 John Wiley & Sons, Inc.
