    Prostaglandin E(2) constrains systemic inflammation through an innate lymphoid cell-IL-22 axis (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-03-19
    Description: Systemic inflammation, which results from the massive release of proinflammatory molecules into the circulatory system, is a major risk factor for severe illness, but the precise mechanisms underlying its control are not fully understood. We observed that prostaglandin E2 (PGE2), through its receptor EP4, is down-regulated in human systemic inflammatory disease. Mice with reduced PGE2 synthesis develop systemic inflammation, associated with translocation of gut bacteria, which can be prevented by treatment with EP4 agonists. Mechanistically, we demonstrate that PGE2-EP4 signaling acts directly on type 3 innate lymphoid cells (ILCs), promoting their homeostasis and driving them to produce interleukin-22 (IL-22). Disruption of the ILC-IL-22 axis impairs PGE2-mediated inhibition of systemic inflammation. Hence, the ILC-IL-22 axis is essential in protecting against gut barrier dysfunction, enabling PGE2-EP4 signaling to impede systemic inflammation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4841390/" 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/PMC4841390/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duffin, Rodger -- O'Connor, Richard A -- Crittenden, Siobhan -- Forster, Thorsten -- Yu, Cunjing -- Zheng, Xiaozhong -- Smyth, Danielle -- Robb, Calum T -- Rossi, Fiona -- Skouras, Christos -- Tang, Shaohui -- Richards, James -- Pellicoro, Antonella -- Weller, Richard B -- Breyer, Richard M -- Mole, Damian J -- Iredale, John P -- Anderton, Stephen M -- Narumiya, Shuh -- Maizels, Rick M -- Ghazal, Peter -- Howie, Sarah E -- Rossi, Adriano G -- Yao, Chengcan -- 106122/Wellcome Trust/United Kingdom -- BB/K091121/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- DK37097/DK/NIDDK NIH HHS/ -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2016 Mar 18;351(6279):1333-8. doi: 10.1126/science.aad9903.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council (MRC) Centre for Inflammation Research, Queen's Medical Research Institute, The University of Edinburgh, Edinburgh EH16 4TJ, UK. ; Division of Pathway Medicine, Edinburgh Infectious Diseases, The University of Edinburgh, Edinburgh EH16 4SB, UK. ; Institute for Immunology and Infection Research, The University of Edinburgh, Edinburgh EH9 3JT, UK. ; MRC Centre for Regenerative Medicine, The University of Edinburgh, Edinburgh EH16 4UU, UK. ; Department of Gastroenterology, First Affiliated Hospital of Jinan University, Guangzhou 510630, China. ; Department of Veterans Affairs, Tennessee Valley Health Authority, Nashville, TN 37212, USA.

    Vascular abnormalities and deregulation of VEGF in Lkb1-deficient mice (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-08-18
    Description: The LKB1 tumor suppressor gene, mutated in Peutz-Jeghers syndrome, encodes a serine/threonine kinase of unknown function. Here we show that mice with a targeted disruption of Lkb1 die at midgestation, with the embryos showing neural tube defects, mesenchymal cell death, and vascular abnormalities. Extraembryonic development was also severely affected; the mutant placentas exhibited defective labyrinth layer development and the fetal vessels failed to invade the placenta. These phenotypes were associated with tissue-specific deregulation of vascular endothelial growth factor (VEGF) expression, including a marked increase in the amount of VEGF messenger RNA. Moreover, VEGF production in cultured Lkb1(-/-) fibroblasts was elevated in both normoxic and hypoxic conditions. These findings place Lkb1 in the VEGF signaling pathway and suggest that the vascular defects accompanying Lkb1 loss are mediated at least in part by VEGF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ylikorkala, A -- Rossi, D J -- Korsisaari, N -- Luukko, K -- Alitalo, K -- Henkemeyer, M -- Makela, T P -- New York, N.Y. -- Science. 2001 Aug 17;293(5533):1323-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular and Cancer Biology Program, Haartman Institute and Biomedicum Helsinki, Post Office Box 63, University of Helsinki, Helsinki 00014, Finland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11509733" target="_blank"〉PubMed〈/a〉

    From marrow to brain: expression of neuronal phenotypes in adult mice (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-12-02
    Description: After intravascular delivery of genetically marked adult mouse bone marrow into lethally irradiated normal adult hosts, donor-derived cells expressing neuronal proteins (neuronal phenotypes) developed in the central nervous system. Flow cytometry revealed a population of donor-derived cells in the brain with characteristics distinct from bone marrow. Confocal microscopy of individual cells showed that hundreds of marrow-derived cells in brain sections expressed gene products typical of neurons (NeuN, 200-kilodalton neurofilament, and class III beta-tubulin) and were able to activate the transcription factor cAMP response element-binding protein (CREB). The generation of neuronal phenotypes in the adult brain 1 to 6 months after an adult bone marrow transplant demonstrates a remarkable plasticity of adult tissues with potential clinical applications.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brazelton, T R -- Rossi, F M -- Keshet, G I -- Blau, H M -- AG09521/AG/NIA NIH HHS/ -- CA59717/CA/NCI NIH HHS/ -- HD18179/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2000 Dec 1;290(5497):1775-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Pharmacology, CCSR 4215, 269 Campus Drive, Stanford University, Stanford, CA 94305-5175, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11099418" target="_blank"〉PubMed〈/a〉

    Comprehensive methylome map of lineage commitment from haematopoietic progenitors (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-08-20
    Description: Epigenetic modifications must underlie lineage-specific differentiation as terminally differentiated cells express tissue-specific genes, but their DNA sequence is unchanged. Haematopoiesis provides a well-defined model to study epigenetic modifications during cell-fate decisions, as multipotent progenitors (MPPs) differentiate into progressively restricted myeloid or lymphoid progenitors. Although DNA methylation is critical for myeloid versus lymphoid differentiation, as demonstrated by the myeloerythroid bias in Dnmt1 hypomorphs, a comprehensive DNA methylation map of haematopoietic progenitors, or of any multipotent/oligopotent lineage, does not exist. Here we examined 4.6 million CpG sites throughout the genome for MPPs, common lymphoid progenitors (CLPs), common myeloid progenitors (CMPs), granulocyte/macrophage progenitors (GMPs), and thymocyte progenitors (DN1, DN2, DN3). Marked epigenetic plasticity accompanied both lymphoid and myeloid restriction. Myeloid commitment involved less global DNA methylation than lymphoid commitment, supported functionally by myeloid skewing of progenitors following treatment with a DNA methyltransferase inhibitor. Differential DNA methylation correlated with gene expression more strongly at CpG island shores than CpG islands. Many examples of genes and pathways not previously known to be involved in choice between lymphoid/myeloid differentiation have been identified, such as Arl4c and Jdp2. Several transcription factors, including Meis1, were methylated and silenced during differentiation, indicating a role in maintaining an undifferentiated state. Additionally, epigenetic modification of modifiers of the epigenome seems to be important in haematopoietic differentiation. Our results directly demonstrate that modulation of DNA methylation occurs during lineage-specific differentiation and defines a comprehensive map of the methylation and transcriptional changes that accompany myeloid versus lymphoid fate decisions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2956609/" 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/PMC2956609/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ji, Hong -- Ehrlich, Lauren I R -- Seita, Jun -- Murakami, Peter -- Doi, Akiko -- Lindau, Paul -- Lee, Hwajin -- Aryee, Martin J -- Irizarry, Rafael A -- Kim, Kitai -- Rossi, Derrick J -- Inlay, Matthew A -- Serwold, Thomas -- Karsunky, Holger -- Ho, Lena -- Daley, George Q -- Weissman, Irving L -- Feinberg, Andrew P -- CA09151/CA/NCI NIH HHS/ -- F32 AI058521/AI/NIAID NIH HHS/ -- F32 AI058521-02/AI/NIAID NIH HHS/ -- F32AI058521/AI/NIAID NIH HHS/ -- P50 HG003233/HG/NHGRI NIH HHS/ -- P50 HG003233-07/HG/NHGRI NIH HHS/ -- P50 HG003233-08/HG/NHGRI NIH HHS/ -- P50HG003233/HG/NHGRI NIH HHS/ -- R00 AG029760/AG/NIA NIH HHS/ -- R00 AG029760-04/AG/NIA NIH HHS/ -- R00AGO29760/PHS HHS/ -- R01 AI047457/AI/NIAID NIH HHS/ -- R01 AI047457-04/AI/NIAID NIH HHS/ -- R01 AI047457-05/AI/NIAID NIH HHS/ -- R01 AI047458/AI/NIAID NIH HHS/ -- R01 CA086065/CA/NCI NIH HHS/ -- R01 GM083084/GM/NIGMS NIH HHS/ -- R01 GM083084-04/GM/NIGMS NIH HHS/ -- R01AI047457/AI/NIAID NIH HHS/ -- R01AI047458/AI/NIAID NIH HHS/ -- R37 CA054358/CA/NCI NIH HHS/ -- R37 CA054358-18/CA/NCI NIH HHS/ -- R37 CA054358-19/CA/NCI NIH HHS/ -- R37CA053458/CA/NCI NIH HHS/ -- England -- Nature. 2010 Sep 16;467(7313):338-42. doi: 10.1038/nature09367.

    Benzothiazinones kill Mycobacterium tuberculosis by blocking arabinan synthesis (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-03-21
    Description: New drugs are required to counter the tuberculosis (TB) pandemic. Here, we describe the synthesis and characterization of 1,3-benzothiazin-4-ones (BTZs), a new class of antimycobacterial agents that kill Mycobacterium tuberculosis in vitro, ex vivo, and in mouse models of TB. Using genetics and biochemistry, we identified the enzyme decaprenylphosphoryl-beta-d-ribose 2'-epimerase as a major BTZ target. Inhibition of this enzymatic activity abolishes the formation of decaprenylphosphoryl arabinose, a key precursor that is required for the synthesis of the cell-wall arabinans, thus provoking cell lysis and bacterial death. The most advanced compound, BTZ043, is a candidate for inclusion in combination therapies for both drug-sensitive and extensively drug-resistant TB.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3128490/" 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/PMC3128490/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Makarov, Vadim -- Manina, Giulia -- Mikusova, Katarina -- Mollmann, Ute -- Ryabova, Olga -- Saint-Joanis, Brigitte -- Dhar, Neeraj -- Pasca, Maria Rosalia -- Buroni, Silvia -- Lucarelli, Anna Paola -- Milano, Anna -- De Rossi, Edda -- Belanova, Martina -- Bobovska, Adela -- Dianiskova, Petronela -- Kordulakova, Jana -- Sala, Claudia -- Fullam, Elizabeth -- Schneider, Patricia -- McKinney, John D -- Brodin, Priscille -- Christophe, Thierry -- Waddell, Simon -- Butcher, Philip -- Albrethsen, Jakob -- Rosenkrands, Ida -- Brosch, Roland -- Nandi, Vrinda -- Bharath, Sowmya -- Gaonkar, Sheshagiri -- Shandil, Radha K -- Balasubramanian, Venkataraman -- Balganesh, Tanjore -- Tyagi, Sandeep -- Grosset, Jacques -- Riccardi, Giovanna -- Cole, Stewart T -- 062511/Wellcome Trust/United Kingdom -- 080039/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2009 May 8;324(5928):801-4. doi: 10.1126/science.1171583.

    Inactivating mutations of acetyltransferase genes in B-cell lymphoma (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-03-11
    Description: B-cell non-Hodgkin's lymphoma comprises biologically and clinically distinct diseases the pathogenesis of which is associated with genetic lesions affecting oncogenes and tumour-suppressor genes. We report here that the two most common types--follicular lymphoma and diffuse large B-cell lymphoma--harbour frequent structural alterations inactivating CREBBP and, more rarely, EP300, two highly related histone and non-histone acetyltransferases (HATs) that act as transcriptional co-activators in multiple signalling pathways. Overall, about 39% of diffuse large B-cell lymphoma and 41% of follicular lymphoma cases display genomic deletions and/or somatic mutations that remove or inactivate the HAT coding domain of these two genes. These lesions usually affect one allele, suggesting that reduction in HAT dosage is important for lymphomagenesis. We demonstrate specific defects in acetylation-mediated inactivation of the BCL6 oncoprotein and activation of the p53 tumour suppressor. These results identify CREBBP/EP300 mutations as a major pathogenetic mechanism shared by common forms of B-cell non-Hodgkin's lymphoma, with direct implications for the use of drugs targeting acetylation/deacetylation mechanisms.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3271441/" 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/PMC3271441/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pasqualucci, Laura -- Dominguez-Sola, David -- Chiarenza, Annalisa -- Fabbri, Giulia -- Grunn, Adina -- Trifonov, Vladimir -- Kasper, Lawryn H -- Lerach, Stephanie -- Tang, Hongyan -- Ma, Jing -- Rossi, Davide -- Chadburn, Amy -- Murty, Vundavalli V -- Mullighan, Charles G -- Gaidano, Gianluca -- Rabadan, Raul -- Brindle, Paul K -- Dalla-Favera, Riccardo -- 1R01LM010140-01/LM/NLM NIH HHS/ -- DE018183/DE/NIDCR NIH HHS/ -- P01 CA092625/CA/NCI NIH HHS/ -- P01 CA092625-05/CA/NCI NIH HHS/ -- P01-CA092625/CA/NCI NIH HHS/ -- P30 CA021765/CA/NCI NIH HHS/ -- R01-CA37295/CA/NCI NIH HHS/ -- R37 CA037295/CA/NCI NIH HHS/ -- R37 CA037295-28/CA/NCI NIH HHS/ -- U54-AI057158/AI/NIAID NIH HHS/ -- England -- Nature. 2011 Mar 10;471(7337):189-95. doi: 10.1038/nature09730.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Cancer Genetics, Herbert Irving Comprehensive Cancer Center, Columbia University, New York, New York 10032, USA. lp171@columbia.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21390126" target="_blank"〉PubMed〈/a〉
