    Cloned viral protein vaccine for foot-and-mouth disease: responses in cattle and swine (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-12-04
    Description: A DNA sequence coding for the immunogenic capsid protein VP3 of foot-and-mouth disease virus A12, prepared from the virion RNA, was ligated to a plasmid designed to express a chimeric protein from the Escherichia coli tryptophan promoter-operator system. When Escherichia coli transformed with this plasmid was grown in tryptophan-depleted media, approximately 17 percent of the total cellular protein was found to be an insoluble and stable chimeric protein. The purified chimeric protein competed equally on a molar basis with VP3 for specific antibodies to foot-and-mouth disease virus. When inoculated into six cattle and two swine, this protein elicited high levels of neutralizing antibody and protection against challenge with foot-and-mouth disease virus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kleid, D G -- Yansura, D -- Small, B -- Dowbenko, D -- Moore, D M -- Grubman, M J -- McKercher, P D -- Morgan, D O -- Robertson, B H -- Bachrach, H L -- New York, N.Y. -- Science. 1981 Dec 4;214(4525):1125-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6272395" target="_blank"〉PubMed〈/a〉

    Germline organization of the murine T cell receptor beta-chain genes (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-10-23
    Description: The complete germline organization of the beta-chain genes of the murine T cell receptor was elucidated in order to obtain the structural basis for understanding the mechanisms of somatic DNA rearrangements. Twenty of the 22 known variable (V beta) genes are clustered within 250 kilobases of DNA 5' to the constant region (C beta) genes. These V beta genes share the same transcriptional orientation as the diversity (D beta), joining (J beta), and C beta genes, which implies that chromosomal deletion is the mechanism for most V beta to D beta-J beta rearrangements. Within this V beta cluster, the distance between the most proximal V beta gene and the D beta-J beta-C beta cluster is 320 kilobases, as determined by field-inversion gel electrophoresis. The large distance between V beta and D beta, relative to that between D beta and J beta, may have significant implications for the ordered rearrangement of the T cell receptor beta-chain genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chou, H S -- Nelson, C A -- Godambe, S A -- Chaplin, D D -- Loh, D Y -- GM07067/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1987 Oct 23;238(4826):545-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Medicine, Washington University School of Medicine, St. Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2821625" target="_blank"〉PubMed〈/a〉

    Alternative mechanisms for activation of human immunodeficiency virus enhancer in T cells (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-03-11
    Description: The expression of human immunodeficiency virus (HIV) after T cell activation is regulated by NF-kappa B, an inducible DNA-binding protein that stimulates transcription. Proteins encoded by a variety of DNA viruses are also able to activate expression from the HIV enhancer. To determine how this activation occurs, specific genes from herpes simplex virus type 1 and adenovirus that activate HIV in T lymphoma cells have been identified. The cis-acting regulatory sequences in the HIV enhancer that mediate their effect have also been characterized. The relevant genes are those for ICP0-an immediate-early product of herpes simplex virus type 1-and the form of E1A encoded by the 13S messenger RNA of adenovirus. Activation of HIV by adenovirus E1A was found to depend on the TATA box, whereas herpesvirus ICP0 did not work through a single defined cis-acting element. These findings suggest multiple pathways that can be used to bypass normal cellular activation of HIV, and they raise the possibility that infection by herpes simplex virus or adenovirus may directly contribute to the activation of HIV in acquired immunodeficiency syndrome by mechanisms independent of antigenic stimulation in T cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nabel, G J -- Rice, S A -- Knipe, D M -- Baltimore, D -- AI20530/AI/NIAID NIH HHS/ -- F32GM11224/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1988 Mar 11;239(4845):1299-302.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2830675" target="_blank"〉PubMed〈/a〉

    Developmental regulation of two 5S ribosomal RNA genes (1988)

    Details
    Publication Date: 1988-09-23
    Description: The developmental regulation of two kinds of Xenopus 5S RNA genes (oocyte and somatic types) can be explained by differences in the stability of protein-protein and protein-DNA interactions in a transcription complex that directs transcription initiation by RNA polymerase III. Dissociation of transcription factors from oocyte 5S RNA genes during development allows them to be repressed by chromatin assembly. In the same cells, somatic 5S RNA genes remain active because their transcription complexes are stable.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wolffe, A P -- Brown, D D -- GM22395/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1988 Sep 23;241(4873):1626-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Embryology, Carnegie Institution of Washington, Baltimore, MD 21210.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3420414" target="_blank"〉PubMed〈/a〉

    Chloride conductance expressed by delta F508 and other mutant CFTRs in Xenopus oocytes (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-12-20
    Description: The cystic fibrosis transmembrane conductance regulator (CFTR) is associated with expression of a chloride conductance that is defective in cystic fibrosis (CF). Xenopus oocytes injected with RNA coding for CFTR that contained mutations in the first nucleotide binding fold (NBF1) expressed chloride currents in response to raising adenosine 3',5'-monophosphate (cAMP) with forskolin and 3-isobutyl-1-methylxanthine (IBMX). The mutant CFTRs were less sensitive than wild-type CFTR to this activating stimulus, and the reduction in sensitivity correlated with the severity of cystic fibrosis in patients carrying the corresponding mutations. This demonstration provides the basis for detailed analyses of NBF1 function and suggests potential pharmacologic treatments for cystic fibrosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drumm, M L -- Wilkinson, D J -- Smit, L S -- Worrell, R T -- Strong, T V -- Frizzell, R A -- Dawson, D C -- Collins, F S -- DK29786/DK/NIDDK NIH HHS/ -- DK39690/DK/NIDDK NIH HHS/ -- DK42718/DK/NIDDK NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1991 Dec 20;254(5039):1797-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Human Genetics, University of Michigan, Ann Arbor 48109.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1722350" target="_blank"〉PubMed〈/a〉

    An ultraviolet-sensitive RNA structural element in a viroid-like domain of the hepatitis delta virus (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-02-03
    Description: The RNA genome of the hepatitis delta virus (HDV) appears to be made up of two parts: a small domain with a high degree of sequence conservation and structural features likely to promote replication; plus a second, larger domain that is less conserved and encodes the delta antigen. This report focuses on one of the several sets of data that have led to the proposal of this model: the existence of a novel structural element in HDV genomic RNA. This structural element lies within the highly conserved domain of HDV RNA and may be related to the local tertiary structure previously mapped to the central conserved region of the plant viroid genome. Both elements occur in regions with no apparent coding capacity and are distinctively responsive to ultraviolet (UV) light. Transcripts containing partial and full-length genomic sequences of HDV readily undergo a UV-induced crosslinking reaction, which establishes a covalent bond between two noncontiguous segments. By locking two segments of the overall structure into place, this crosslink has permitted the unbranched, rodlike model of HDV RNA to be examined and confirmed in the portion of the RNA analyzed. The clustering of the novel tertiary structure and the recently discovered self-cleavage sites into a highly conserved, but apparently noncoding, portion of the genome defines a viroid-like domain in HDV RNA and raises questions about the possible events leading up to the association of free-living RNAs with messenger RNAs and other RNA molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Branch, A D -- Benenfeld, B J -- Baroudy, B M -- Wells, F V -- Gerin, J L -- Robertson, H D -- DA-5130/DA/NIDA NIH HHS/ -- GM-28294/GM/NIGMS NIH HHS/ -- N01-AI-72623/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1989 Feb 3;243(4891):649-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetics, Rockefeller University, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2492676" target="_blank"〉PubMed〈/a〉

    Ikaros, an early lymphoid-specific transcription factor and a putative mediator for T cell commitment (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-10-30
    Description: In a screen for transcriptional regulators that control differentiation into the T cell lineage, a complementary DNA was isolated encoding a zinc finger protein (Ikaros) related to the Drosophila gap protein Hunchback. The Ikaros protein binds to and activates the enhancer of a gene encoding an early T cell differentiation antigen, CD3 delta. During development, Ikaros messenger RNA was first detected in the mouse fetal liver and the embryonic thymus when hematopoietic and lymphoid progenitors initially colonize these organs; no expression was observed in the spleen or the bone marrow. The pattern of Ikaros gene expression and its ability to stimulate CD3 delta transcription support the model that Ikaros functions in the specification and maturation of the T lymphocyte.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Georgopoulos, K -- Moore, D D -- Derfler, B -- New York, N.Y. -- Science. 1992 Oct 30;258(5083):808-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cutaneous Biology Research Center, Harvard Medical School, Massachusetts General Hospital, Charlestown 02114.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1439790" target="_blank"〉PubMed〈/a〉

    Wound macrophages express TGF-alpha and other growth factors in vivo: analysis by mRNA phenotyping (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-08-05
    Description: The presence of macrophages is required for the regeneration of many cell types during wound healing. Macrophages have been reported to express a wide range of mitogenic factors and cytokines, but none of these factors has been shown in vivo to sustain all the wound-healing processes. It has been suggested that transforming growth factor-alpha (TGF-alpha) may mediate angiogenesis, epidermal regrowth, and formation of granulation tissue in vivo. Macrophages isolated from a wound site, and not exposed to cell culture conditions, expressed messenger RNA transcripts for TGF-alpha, TGF-beta, platelet-derived growth factor A-chain, and insulin-like growth factor-1. The expression of these transcripts was determined by a novel method for RNA analysis in which low numbers of mouse macrophages were isolated from wound cylinders, their RNA was purified and reverse-transcribed, and the complementary DNA was amplified in a polymerase chain reaction primed with growth factor sequence-specific primers. This single-cell RNA phenotyping procedure is rapid and has the potential for quantification, and mRNA transcripts from a single cell or a few cells can be unambiguously demonstrated, with the simultaneous analysis of several mRNA species. Macrophages from wounds expressed TGF-alpha antigen, and wound fluids contained TGF-alpha. Elicited macrophages in culture also expressed TGF-alpha transcripts and polypeptide in a time-dependent manner after stimulation with modified low-density lipoproteins and lipopolysaccharide endotoxin, which are characteristic of the activators found in injured tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rappolee, D A -- Mark, D -- Banda, M J -- Werb, Z -- AR 32746/AR/NIAMS NIH HHS/ -- GM 27345/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1988 Aug 5;241(4866):708-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Radiobiology and Environmental Health, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3041594" target="_blank"〉PubMed〈/a〉

    Molecular cloning of the zeta chain of the T cell antigen receptor (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-02-26
    Description: The T cell antigen receptor is a multi-subunit receptor complex present on the surface of all mature and many developing T cells. It consists of clonotypic heterodimers noncovalently linked to five invariant chains that are encoded by four genes and referred to as the CD3 complex. The CD3 gamma, delta, and epsilon chains have been molecularly characterized. In this report the molecular cloning of a complementary DNA encoding the zeta chain of the murine T cell antigen receptor is described. The predicted protein sequence of the zeta chain suggests a structure distinct from those of any of the previously described receptor subunits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weissman, A M -- Baniyash, M -- Hou, D -- Samelson, L E -- Burgess, W H -- Klausner, R D -- New York, N.Y. -- Science. 1988 Feb 26;239(4843):1018-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cell Biology and Metabolism Branch, National Institute of Child Health and Human Development, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3278377" target="_blank"〉PubMed〈/a〉

    Developmental expression of PDGF, TGF-alpha, and TGF-beta genes in preimplantation mouse embryos (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-09-30
    Description: Control of growth and differentiation during mammalian embryogenesis may be regulated by growth factors from embryonic or maternal sources. With the use of single-cell messenger RNA phenotyping, the simultaneous expression of growth factor transcripts in single or small numbers of preimplantation mouse embryos was examined. Transcripts for platelet-derived growth factor A chain (PDGF-A), transforming growth factor (TGF)-alpha, and TGF-beta 1, but not for four other growth factors, were found in whole blastocysts. TGF-alpha, TGF-beta 1, and PDGF antigens were detected in blastocysts by immunocytochemistry. Both PDGF-A and TGF-alpha were detected as maternal transcripts in the unfertilized ovulated oocyte, and again in blastocysts. TGF-beta 1 transcripts appeared only after fertilization. The expression of a subset of growth factors in mouse blastocysts suggests a role for these factors in the growth and differentiation of early mammalian embryos.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rappolee, D A -- Brenner, C A -- Schultz, R -- Mark, D -- Werb, Z -- 5T32 ES07106/ES/NIEHS NIH HHS/ -- HD22681/HD/NICHD NIH HHS/ -- HD23539/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1988 Sep 30;241(4874):1823-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Radiobiology and Environmental Health, University of California, San Francisco 94143-0750.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3175624" target="_blank"〉PubMed〈/a〉
