    Isolation and expression of functional high-affinity Fc receptor complementary DNAs (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-01-20
    Description: Human and murine mononuclear phagocytes express a high-affinity receptor for immunoglobulin G that plays a central role in macrophage antibody-dependent cellular cytotoxicity and clearance of immune complexes. The receptor (FcRI) may also be involved in CD4-independent infection of human macrophages by human immunodeficiency virus. This report describes the isolation of cDNA clones encoding the human FcRI by a ligand-mediated selection technique. Expression of the cDNAs in COS cells gave rise to immunoglobulin G binding of the expected affinity and subtype specificity. RNA blot analysis revealed expression of a 1.7-kilobase transcript in macrophages and in cells of the promonocytic cell line U937 induced with interferon-gamma. The extracellular region of FcRI consists of three immunoglobulin-like domains, two of which share homology with low-affinity receptor domains.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Allen, J M -- Seed, B -- New York, N.Y. -- Science. 1989 Jan 20;243(4889):378-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Massachusetts General Hospital, Boston 02114.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2911749" target="_blank"〉PubMed〈/a〉

    Freeze avoidance in a mammal: body temperatures below 0 degree C in an Arctic hibernator (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-06-30
    Description: Hibernating arctic ground squirrels, Spermophilus parryii, were able to adopt and spontaneously arouse from core body temperatures as low as -2.9 degrees C without freezing. Abdominal body temperatures of ground squirrels hibernating in outdoor burrows were recorded with temperature-sensitive radiotransmitter implants. Body temperatures and soil temperatures at hibernaculum depth reached average minima during February of -1.9 degrees and -6 degrees C, respectively. Laboratory-housed ground squirrels hibernating in ambient temperatures of -4.3 degrees C maintained above 0 degree C thoracic temperatures but decreased colonic temperatures to as low as -1.3 degrees C. Plasma sampled from animals with below 0 degree C body temperatures had normal solute concentrations and showed no evidence of containing antifreeze molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barnes, B M -- HD 23383/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 30;244(4912):1593-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Arctic Biology, University of Alaska Fairbanks, Fairbanks 99775-0180.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2740905" target="_blank"〉PubMed〈/a〉

    Temperature and sperm incorporation in polyploid salamanders (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-11-24
    Description: Although most animals reproduce sexually, a number of all-female groups exist. Triploid hybrid salamanders appear to maintain themselves by using a male's sperm to activate their eggs, after which the sperm nucleus is eliminated (gynogenesis). The incidence of sperm nuclear incorporation in eggs of these salamanders depends on temperature. Triploid offspring derived gynogenetically are more frequent at lower temperature, whereas tetraploid offspring derived sexually are far more frequent at higher temperatures. Temperature-dependent variability in sperm nuclear incorporation helps explain the variability in reproductive modes reported for hybrid salamanders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bogart, J P -- Elinson, R P -- Licht, L E -- New York, N.Y. -- Science. 1989 Nov 24;246(4933):1032-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, College of Biological Science, University of Guelph, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2587986" target="_blank"〉PubMed〈/a〉

    Endothelial interleukin-8: a novel inhibitor of leukocyte-endothelial interactions (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-12-22
    Description: Certain inflammatory stimuli render cultured human vascular endothelial cells hyperadhesive for neutrophils. This state is transient and reversible, in part because activated endothelial cells secrete a leukocyte adhesion inhibitor (LAI). LAI was identified as endothelial interleukin-8 (IL-8), the predominant species of which is an extended amino-terminal IL-8 variant. At nanomolar concentrations, purified endothelial IL-8 and recombinant human IL-8 inhibit neutrophil adhesion to cytokine-activated endothelial monolayers and protect these monolayers from neutrophil-mediated damage. These findings suggest that endothelial-derived IL-8 may function to attenuate inflammatory events at the interface between vessel wall and blood.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gimbrone, M A Jr -- Obin, M S -- Brock, A F -- Luis, E A -- Hass, P E -- Hebert, C A -- Yip, Y K -- Leung, D W -- Lowe, D G -- Kohr, W J -- P01-HL-36028/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Dec 22;246(4937):1601-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2688092" target="_blank"〉PubMed〈/a〉

    The economic status of the elderly (1989)

    Details
    Publication Date: 1989-05-12
    Description: Augmented by public programs such as Social Security and Medicare, incomes of the elderly in the United States have grown more rapidly during the last several decades than have the incomes of other groups, so that on average the elderly are at least as well off as the nonelderly. Not all elderly, however, have done as well: widows, in particular, have high poverty rates. The economic prospects of the elderly during the next few decades are good because of the large work force from the baby-boom cohort. In the distant future a large fraction of the population will be elderly, which will probably lead to a deterioration in their economic status. Today, the main problems center on the distribution of economic resources among the elderly and on uncertainties such as costs of medical care.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hurd, M D -- New York, N.Y. -- Science. 1989 May 12;244(4905):659-64.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Economics, State University of New York, Stony Brook 11794.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2655090" target="_blank"〉PubMed〈/a〉

    Description: A novel bacteriophage lambda vector system was used to express in Escherichia coli a combinatorial library of Fab fragments of the mouse antibody repertoire. The system allows rapid and easy identification of monoclonal Fab fragments in a form suitable for genetic manipulation. It was possible to generate, in 2 weeks, large numbers of monoclonal Fab fragments against a transition state analog hapten. The methods described may supersede present-day hybridoma technology and facilitate the production of catalytic and other antibodies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huse, W D -- Sastry, L -- Iverson, S A -- Kang, A S -- Alting-Mees, M -- Burton, D R -- Benkovic, S J -- Lerner, R A -- New York, N.Y. -- Science. 1989 Dec 8;246(4935):1275-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Research Institute of Scripps Clinic, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2531466" target="_blank"〉PubMed〈/a〉

The antibodies were produced by immunizing with a Co(III) triethylenetetramine (trien)-peptide hapten. These antibodies as a group are capable of binding trien complexes of not only Co(III) but also of numerous other metals. Six peptides were examined as possible substrates with the antibodies and various metal complexes. Two of these peptides were cleaved by several of the antibodies. One antibody was studied in detail, and cleavage was observed for the substrates with the trien complexes of Zn(II), Ga(III), Fe(III), In(III), Cu(II), Ni(II), Lu(III), Mg(II), or Mn(II) as cofactors. A turnover number of 6 x 10(-4) per second was observed for these substrates. These results demonstrate the feasibility of the use of cofactor-assisted catalysis in an antibody binding site to accomplish difficult chemical transformations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Iverson, B L -- Lerner, R A -- New York, N.Y. -- Science. 1989 Mar 3;243(4895):1184-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Research Institute of Scripps Clinic, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2922606" target="_blank"〉PubMed〈/a〉

    Golf: an olfactory neuron specific-G protein involved in odorant signal transduction (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-05-19
    Description: Biochemical and electrophysiological studies suggest that odorants induce responses in olfactory sensory neurons via an adenylate cyclase cascade mediated by a G protein. An olfactory-specific guanosine triphosphate (GTP)-binding protein alpha subunit has now been characterized and evidence is presented suggesting that this G protein, termed Golf, mediates olfaction. Messenger RNA that encodes Golf alpha is expressed in olfactory neuroephithelium but not in six other tissues tested. Moreover, within the olfactory epithelium, Golf alpha appears to be expressed only by the sensory neurons. Specific antisera were used to localize Golf alpha protein to the sensory apparatus of the receptor neurons. Golf alpha shares extensive amino acid identity (88 percent) with the stimulatory G protein, Gs alpha. The expression of Golf alpha in S49 cyc- kin- cells, a line deficient in endogenous stimulatory G proteins, demonstrates its capacity to stimulate adenylate cyclase in a heterologous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jones, D T -- Reed, R R -- New York, N.Y. -- Science. 1989 May 19;244(4906):790-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular Biology and Genetic Johns Hopkins School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2499043" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-01-13
    Description: The chemical synthesis of biologically active peptides and polypeptides can be achieved by using a convergent strategy of condensing protected peptide segments to form the desired molecule. An oxime support increases the ease with which intermediate protected peptides can be synthesized and makes this approach useful for the synthesis of peptides in which secondary structural elements have been redesigned. The extension of these methods to large peptides and proteins, for which folding of secondary structures into functional tertiary structures is critical, is discussed. Models of apolipoproteins, the homeo domain from the developmental protein encoded by the Antennapedia gene of Drosophila, a part of the Cro repressor, and the enzyme ribonuclease T1 and a structural analog have been synthesized with this method.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaiser, E T -- Mihara, H -- Laforet, G A -- Kelly, J W -- Walters, L -- Findeis, M A -- Sasaki, T -- DK07825/DK/NIDDK NIH HHS/ -- GM12054/GM/NIGMS NIH HHS/ -- HL-186577/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Jan 13;243(4888):187-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Bioorganic Chemistry and Biochemistry, Rockefeller University, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2492114" target="_blank"〉PubMed〈/a〉

    Defensive behaviors in infant rhesus monkeys: environmental cues and neurochemical regulation (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-03-31
    Description: To survive, primates must detect danger in time to activate appropriate defensive behaviors. In this study, the defensive behaviors of infant rhesus monkeys exposed to humans were characterized. It was observed that the direction of the human's gaze is a potent cue for the infant. Infants separated from their mothers were active and emitted frequent distress vocalizations. When a human entered the room but did not look at the infant, it became silent and froze in one position. If the human stared at the infant, it responded with aggressive barking. Alterations of the opiate system affected the frequency of the infant's distress calls without affecting barking and freezing, whereas benzodiazepine administration selectively reduced barking and freezing. This suggests that opiate and benzodiazepine systems regulate specific defensive behaviors in primates and that these systems work together to mediate behavioral responses important for survival.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kalin, N H -- Shelton, S E -- DK-35641/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1989 Mar 31;243(4899):1718-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, University of Wisconsin, Madison.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2564702" target="_blank"〉PubMed〈/a〉

    Vascular permeability factor, an endothelial cell mitogen related to PDGF (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-12-08
    Description: Vascular permeability factor (VPF) is a 40-kilodalton disulfide-linked dimeric glycoprotein that is active in increasing blood vessel permeability, endothelial cell growth, and angiogenesis. These properties suggest that the expression of VPF by tumor cells could contribute to the increased neovascularization and vessel permeability that are associated with tumor vasculature. The cDNA sequence of VPF from human U937 cells was shown to code for a 189-amino acid polypeptide that is similar in structure to the B chain of platelet-derived growth factor (PDGF-B) and other PDGF-B-related proteins. The overall identity with PDGF-B is 18%. However, all eight of the cysteines in PDGF-B were found to be conserved in human VPF, an indication that the folding of the two proteins is probably similar. Clusters of basic amino acids in the COOH-terminal halves of human VPF and PDGF-B are also prevalent. Thus, VPF appears to be related to the PDGF/v-sis family of proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keck, P J -- Hauser, S D -- Krivi, G -- Sanzo, K -- Warren, T -- Feder, J -- Connolly, D T -- New York, N.Y. -- Science. 1989 Dec 8;246(4935):1309-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Culture and Biochemistry, Monsanto Company, St. Louis, MO 63167.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2479987" target="_blank"〉PubMed〈/a〉

    Corticosteroid modulation of hippocampal potentials: increased effect with aging (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-09-29
    Description: Adrenal steroids bind specifically to hippocampal neurons under normal conditions and may contribute to hippocampal cell loss during aging, but little is known about the neurophysiological mechanisms by which they may change hippocampal cell functions. In the present studies, adrenal steroids have been shown to modulate a well-defined membrane conductance in hippocampal pyramidal cells. The calcium-dependent slow afterhyperpolarization is reduced in hippocampal slices from adrenalectomized rats, and it is increased after in vivo or in vitro administration of the adrenal steroid, corticosterone. Calcium action potentials are also reduced in adrenalectomized animals, indicating that the primary effect of corticosteroids may be on calcium conductance. The afterhyperpolarization component reduced by adrenalectomy is greater in aged rats than in young rats, suggesting that, with aging, there is an increased effect of corticosteroids on some calcium-mediated brain processes. Because elevated concentrations of intracellular calcium can be cytotoxic, these observations may increase the understanding of glucocorticoid involvement in brain aging as well as of the normal functions of these steroids in the brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kerr, D S -- Campbell, L W -- Hao, S Y -- Landfield, P W -- AG04542/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1989 Sep 29;245(4925):1505-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology and Pharmacology, Bowman Gray School of Medicine, Winston-Salem, NC 27103.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2781293" target="_blank"〉PubMed〈/a〉

    Switch protein alters specificity of RNA polymerase containing a compartment-specific sigma factor (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-01-27
    Description: During sporulation in Bacillus subtilis, expression of developmental genes spoIVCB and cotD is induced in the mother cell compartment of the sporangium at morphological stages IV and V, respectively. A 27-kilodalton RNA polymerase sigma factor called sigma K (or sigma 27) has been found that causes weak transcription of spoIVCB and strong transcription of cotD. A 14-kD protein was also discovered that changes the specificity of sigma K-containing RNA polymerase, greatly stimulating spoIVCB transcription and markedly repressing cotD transcription. Both sigma K and the 14-kD protein are products of genes known to be required for expression of specific genes in the mother cell. Thus, sigma K directs gene expression in the mother cell and it is proposed that inactivation or sequestering of the 14-kD protein switches the temporal pattern of gene expression during the transition from stages IV to V of development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kroos, L -- Kunkel, B -- Losick, R -- GM18568/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jan 27;243(4890):526-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Developmental Biology, Harvard University, Cambridge, Massachusetts 02138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2492118" target="_blank"〉PubMed〈/a〉

    Description: Protein engineering and x-ray crystallography have been used to study the role of a surface loop that is present in pancreatic phospholipases but is absent in snake venom phospholipases. Removal of residues 62 to 66 from porcine pancreatic phospholipase A2 does not change the binding constant for micelles significantly, but it improves catalytic activity up to 16 times on micellar (zwitterionic) lecithin substrates. In contrast, the decrease in activity on negatively charged substrates is greater than fourfold. A crystallographic study of the mutant enzyme shows that the region of the deletion has a well-defined structure that differs from the structure of the wild-type enzyme. No structural changes in the active site of the enzyme were detected.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuipers, O P -- Thunnissen, M M -- de Geus, P -- Dijkstra, B W -- Drenth, J -- Verheij, H M -- de Haas, G H -- New York, N.Y. -- Science. 1989 Apr 7;244(4900):82-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Utrecht, The Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2704992" target="_blank"〉PubMed〈/a〉

    Publication Date: 1989-06-30
    Description: Complementary DNA's that encode an adenylyl cyclase were isolated from a bovine brain library. Most of the deduced amino acid sequence of 1134 residues is divisible into two alternating sets of hydrophobic and hydrophilic domains. Each of the two large hydrophobic domains appears to contain six transmembrane spans. Each of the two large hydrophilic domains contains a sequence that is homologous to a single cytoplasmic domain of several guanylyl cyclases; these sequences may represent nucleotide binding sites. An unexpected topographical resemblance between adenylyl cyclase and various plasma membrane channels and transporters was observed. This structural complexity suggests possible, unappreciated functions for this important enzyme.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Krupinski, J -- Coussen, F -- Bakalyar, H A -- Tang, W J -- Feinstein, P G -- Orth, K -- Slaughter, C -- Reed, R R -- Gilman, A G -- CA16519/CA/NCI NIH HHS/ -- GM12230/GM/NIGMS NIH HHS/ -- GM34497/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Jun 30;244(4912):1558-64.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Texas Southwestern Medical Center, Dallas 75235.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2472670" target="_blank"〉PubMed〈/a〉

    Description: A specific assay has been developed for a blood-borne non-A, non-B hepatitis (NANBH) virus in which a polypeptide synthesized in recombinant yeast clones of the hepatitis C virus (HCV) is used to capture circulating viral antibodies. HCV antibodies were detected in six of seven human sera that were shown previously to transmit NANBH to chimpanzees. Assays of ten blood transfusions in the United States that resulted in chronic NANBH revealed that there was at least one positive blood donor in nine of these cases and that all ten recipients seroconverted during their illnesses. About 80 percent of chronic, post-transfusion NANBH (PT-NANBH) patients from Italy and Japan had circulating HCV antibody; a much lower frequency (15 percent) was observed in acute, resolving infections. In addition, 58 percent of NANBH patients from the United States with no identifiable source of parenteral exposure to the virus were also positive for HCV antibody. These data indicate that HCV is a major cause of NANBH throughout the world.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuo, G -- Choo, Q L -- Alter, H J -- Gitnick, G L -- Redeker, A G -- Purcell, R H -- Miyamura, T -- Dienstag, J L -- Alter, M J -- Stevens, C E -- New York, N.Y. -- Science. 1989 Apr 21;244(4902):362-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Chiron Corporation, Emeryville, CA 94608.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2496467" target="_blank"〉PubMed〈/a〉

    The MHC-binding and gp120-binding functions of CD4 are separable (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-08-18
    Description: CD4 is a cell surface glycoprotein that is thought to interact with nonpolymorphic determinants of class II major histocompatibility (MHC) molecules. CD4 is also the receptor for the human immunodeficiency virus (HIV), binding with high affinity to the HIV-1 envelope glycoprotein, gp120. Homolog-scanning mutagenesis was used to identify CD4 regions that are important in class II MHC binding and to determine whether the gp120 and class II MHC binding sites of CD4 are related. Class II MHC binding was abolished by mutations in each of the first three immunoglobulin-like domains of CD4. The gp120 binding could be abolished without affecting class II MHC binding and vice versa, although at least one mutation examined reduced both functions significantly. These findings indicate that, while there may be overlap between the gp120 and class II MHC binding sites of CD4, these sites are distinct and can be separated. Thus it should be possible to design CD4 analogs that can block HIV infectivity but intrinsically lack the ability to affect the normal immune response by binding to class II MHC molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lamarre, D -- Ashkenazi, A -- Fleury, S -- Smith, D H -- Sekaly, R P -- Capon, D J -- New York, N.Y. -- Science. 1989 Aug 18;245(4919):743-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire d'Immunologie, Institut de Recherches Cliniques de Montreal, Quebec, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2549633" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1989-02-24
    Description: Branched RNA-linked multicopy single-stranded DNA (msDNA) originally detected in myxobacteria has now been found in a clinical isolate of Escherichia coli. Although lacking homology in the primary structure, the E. coli msDNA is similar in secondary structure to the myxobacterial msDNA's, including the 2',5'-phosphodiester linkage between RNA and DNA. A chromosomal DNA fragment responsible for the production of msDNA was cloned in an E. coli K12 strain; its DNA sequence revealed an open reading frame (ORF) of 586 amino acid residues. The ORF shows sequence similarity with retroviral reverse transcriptases and ribonuclease H. Disruption of the ORF blocked msDNA production, indicating that this gene is essential for msDNA synthesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lampson, B C -- Sun, J -- Hsu, M Y -- Vallejo-Ramirez, J -- Inouye, S -- Inouye, M -- F32 GM11970-01A1/GM/NIGMS NIH HHS/ -- GM26843/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Feb 24;243(4894 Pt 1):1033-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Robert Wood Johnson Medical School, University of Medicine and Dentistry of New Jersey, Piscataway 08854.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2466332" target="_blank"〉PubMed〈/a〉

    The DNA binding domain of the rat liver nuclear protein C/EBP is bipartite (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-03-31
    Description: C/EBP is a rat liver nuclear protein capable of sequence-specific interaction with DNA. The DNA sequences to which C/EBP binds in vitro have been implicated in the control of messenger RNA synthesis. It has therefore been predicted that C/EBP will play a role in regulating gene expression in mammalian cells. The region of the C/EBP polypeptide required for direct interaction with DNA has been identified and shown to bear amino acid sequence relatedness with the product of the myc, fos, and jun proto-oncogenes. The arrangement of these related amino acid sequences led to the prediction of a new structural motif, termed the "leucine zipper," that plays a role in facilitating sequence-specific interaction between protein and DNA. Experimental tests now provide support for the leucine zipper hypothesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Landschulz, W H -- Johnson, P F -- McKnight, S L -- New York, N.Y. -- Science. 1989 Mar 31;243(4899):1681-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Carnegie Institution of Washington, Department of Embryology, Baltimore, MD 21210.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2494700" target="_blank"〉PubMed〈/a〉

    Multiple mutations in HIV-1 reverse transcriptase confer high-level resistance to zidovudine (AZT) (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-12-01
    Description: Human immunodeficiency virus (HIV) isolates with reduced sensitivity to zidovudine (3'-azido-3'-deoxythymidine, AZT) from individuals with acquired immunodeficiency syndrome (AIDS) or AIDS-related complex were studied to determine the genetic basis of their resistance. Most were sequential isolates obtained at the initiation of and during therapy. Comparative nucleotide sequence analysis of the reverse transcriptase (RT) coding region from five pairs of sensitive and resistant isolates identified three predicted amino acid substitutions common to all the resistant strains (Asp67----Asn, Lys70----Arg, Thr215----Phe or Tyr) plus a fourth in three isolates (Lys219----Gln). Partially resistant isolates had combinations of these four changes. An infectious molecular clone constructed with these four mutations in RT yielded highly resistant HIV after transfection of T cells. The reproducible nature of these mutations should make it possible to develop rapid assays to predict zidovudine resistance by performing polymerase chain reaction amplification of nucleic acid from peripheral blood lymphocytes, thereby circumventing current lengthy HIV isolation and sensitivity testing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Larder, B A -- Kemp, S D -- New York, N.Y. -- Science. 1989 Dec 1;246(4934):1155-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Sciences Department, Wellcome Research Laboratories, Beckenham, Kent, United Kingdom.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2479983" target="_blank"〉PubMed〈/a〉

    Monitoring the AIDS epidemic in the United States: a network approach (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-06-09
    Description: Respondents in the 1988 General Social Survey (GSS) were asked to scan their acquaintance networks to identify all those who had been a victim of a homicide or had acquired immunodeficiency syndrome (AIDS). Estimates of the sex, race, age, and regional breakdowns for homicides in the last year and for people with AIDS were compared with official statistics. The GSS estimates for the distribution of homicide victims replicate the official statistics quite well. The GSS estimates for AIDS cases suggest that the data provided to the Centers for Disease Control may underestimate by a substantial margin the prevalence of AIDS in the white population of higher socioeconomic status, overstate the relative prevalence of the disease in the minority populations, underestimate the prevalence of the disease in the Midwest, and overstate it for the East.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Laumann, E O -- Gagnon, J H -- Michaels, S -- Michael, R T -- Coleman, J S -- N0I-HD-8-2907/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 9;244(4909):1186-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Sociology, University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2543079" target="_blank"〉PubMed〈/a〉

    Identification of the molecular defect in a family with spondyloepiphyseal dysplasia (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-05-26
    Description: Spondyloepiphyseal dysplasias (SED) are a heterogeneous group of inherited disorders characterized by disproportionate short stature and pleiotropic involvement of the skeletal and ocular systems. Evidence has suggested that SED may result from structural defects in type II collagen. To confirm the validity of this hypothesis, the structure of the "candidate" type II collagen gene (COL2A1) has been directly examined in a relatively large SED family. Coarse scanning of the gene by Southern blot hybridization identified an abnormal restriction pattern in one of the affected members of the kindred. Analysis of selected genomic fragments, amplified by the polymerase chain reaction, precisely localized the molecular defect and demonstrated that all affected family members carried the same heterozygous single-exon deletion. As a consequence of the mutation, nearly 90 percent of the assembled type II collagen homotrimers are expected to contain one or more procollagen subunits harboring an interstitial deletion of 36 amino acids in the triple helical domain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, B -- Vissing, H -- Ramirez, F -- Rogers, D -- Rimoin, D -- AR-38648/AR/NIAMS NIH HHS/ -- HD-22657/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1989 May 26;244(4907):978-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, State University of New York Health Science Center, Brooklyn 11203.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2543071" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1989-07-07
    Description: Basic fibroblast growth factor (bFGF) participates in many processes including early developmental events, angiogenesis, wound healing, and maintenance of neuronal cell viability. A 130-kilodalton protein was isolated on the basis of its ability to specifically bind to bFGF. A complementary DNA clone was isolated with an oligonucleotide probe corresponding to determined amino acid sequences of tryptic peptide fragments of the purified protein. The putative bFGF receptor encoded by this complementary DNA is a transmembrane protein that contains three extracellular immunoglobulin-like domains, an unusual acidic region, and an intracellular tyrosine kinase domain. These domains are arranged in a pattern that is different from that of any growth factor receptor described.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, P L -- Johnson, D E -- Cousens, L S -- Fried, V A -- Williams, L T -- CA 21765/CA/NCI NIH HHS/ -- R01 HL32898/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Jul 7;245(4913):57-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Medicine, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2544996" target="_blank"〉PubMed〈/a〉

    Three-dimensional solution structure of a single zinc finger DNA-binding domain (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-08-11
    Description: The three-dimensional solution structure of a zinc finger nucleic acid binding motif has been determined by nuclear magnetic resonance (NMR) spectroscopy. Spectra of a synthetic peptide corresponding to a single zinc finger from the Xenopus protein Xfin yielded distance and dihedral angle constraints that were used to generate structures from distance geometry and restrained molecular dynamics calculations. The zinc finger is an independently folded domain with a compact globular structure in which the zinc atom is bound by two cysteine and two histidine ligands. The polypeptide backbone fold consists of a well-defined helix, starting as alpha and ending as 3(10) helix, packed against two beta strands that are arranged in a hairpin structure. A high density of basic and polar amino acid side chains on the exposed face of the helix are probably involved in DNA binding.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, M S -- Gippert, G P -- Soman, K V -- Case, D A -- Wright, P E -- GM 36643/GM/NIGMS NIH HHS/ -- GM38794/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Aug 11;245(4918):635-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Research Institute of Scripps Clinic, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2503871" target="_blank"〉PubMed〈/a〉

    Secretion of activin by interstitial cells in the testis (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-01-20
    Description: Activin, a dimer formed by the beta subunits of inhibin, has an effect that is opposite to that of inhibin in a number of biological systems. Which cell types secrete activin in vivo is not known. TM3 cells, a Leydig-derived cell line, contained messenger RNAs that hybridized with human beta A and beta B complementary DNA probes and were similar in size to the porcine messenger RNA for the beta subunits of inhibin. No hybridization to the inhibin alpha subunit was detectable in the TM3 cells. Conditioned medium from TM3 cells and from primary cultures of rat and porcine interstitial cells stimulated the release of follicle-stimulating hormone in a pituitary cell culture assay. It is likely that, in the testis, the Leydig cells secrete activin and the Sertoli cells produce inhibin, or a combination of both.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, W -- Mason, A J -- Schwall, R -- Szonyi, E -- Mather, J P -- New York, N.Y. -- Science. 1989 Jan 20;243(4889):396-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Culture, Genentech, South San Francisco, CA 94080.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2492117" target="_blank"〉PubMed〈/a〉

    Vascular endothelial growth factor is a secreted angiogenic mitogen (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-12-08
    Description: Vascular endothelial growth factor (VEGF) was purified from media conditioned by bovine pituitary folliculostellate cells (FC). VEGF is a heparin-binding growth factor specific for vascular endothelial cells that is able to induce angiogenesis in vivo. Complementary DNA clones for bovine and human VEGF were isolated from cDNA libraries prepared from FC and HL60 leukemia cells, respectively. These cDNAs encode hydrophilic proteins with sequences related to those of the A and B chains of platelet-derived growth factor. DNA sequencing suggests the existence of several molecular species of VEGF. VEGFs are secreted proteins, in contrast to other endothelial cell mitogens such as acidic or basic fibroblast growth factors and platelet-derived endothelial cell growth factor. Human 293 cells transfected with an expression vector containing a bovine or human VEGF cDNA insert secrete an endothelial cell mitogen that behaves like native VEGF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leung, D W -- Cachianes, G -- Kuang, W J -- Goeddel, D V -- Ferrara, N -- New York, N.Y. -- Science. 1989 Dec 8;246(4935):1306-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Genetech, South San Francisco, CA 94080.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2479986" target="_blank"〉PubMed〈/a〉

    Publication Date: 1989-05-05
    Description: An approach based on the polymerase chain reaction has been devised to clone new members of the family of genes encoding guanosine triphosphate-binding protein (G protein)-coupled receptors. Degenerate primers corresponding to consensus sequences of the third and sixth transmembrane segments of available receptors were used to selectively amplify and clone members of this gene family from thyroid complementary DNA. Clones encoding three known receptors and four new putative receptors were obtained. Sequence comparisons established that the new genes belong to the G protein-coupled receptor family. Close structural similarity was observed between one of the putative receptors and the 5HT1a receptor. Two other molecules displayed common sequence characteristics, suggesting that they are members of a new subfamily of receptors with a very short nonglycosylated (extracellular) amino-terminal extension.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Libert, F -- Parmentier, M -- Lefort, A -- Dinsart, C -- Van Sande, J -- Maenhaut, C -- Simons, M J -- Dumont, J E -- Vassart, G -- New York, N.Y. -- Science. 1989 May 5;244(4904):569-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Recherche Interdisciplinaire, Faculte de Medecine, Universite Libre de Bruxelles, Campus Erasme, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2541503" target="_blank"〉PubMed〈/a〉

    Description: Ciliary neurotrophic factor (CNTF) is one of a small number of proteins with neurotrophic activities distinct from nerve growth factor (NGF). CNTF has now been purified and cloned and the primary structure of CNTF from rabbit sciatic nerve has been determined. Biologically active CNTF has been transiently expressed from a rabbit complementary DNA clone. CNTF is a neural effector without significant sequence homologies to any previously reported protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, L F -- Mismer, D -- Lile, J D -- Armes, L G -- Butler, E T 3rd -- Vannice, J L -- Collins, F -- New York, N.Y. -- Science. 1989 Nov 24;246(4933):1023-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Protein Chemistry Group, Synergen, Inc., Boulder, CO 80301.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2587985" target="_blank"〉PubMed〈/a〉

    Polymerase chain reaction with single-sided specificity: analysis of T cell receptor delta chain (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-01-13
    Description: In the polymerase chain reaction (PCR), two specific oligonucleotide primers are used to amplify the sequences between them. However, this technique is not suitable for amplifying genes that encode molecules where the 5' portion of the sequences of interest is not known, such as the T cell receptor (TCR) or immunoglobulins. Because of this limitation, a novel technique, anchored polymerase chain reaction (A-PCR), was devised that requires sequence specificity only on the 3' end of the target fragment. It was used to analyze TCR delta chain mRNA's from human peripheral blood gamma delta T cells. Most of these cells had a V delta gene segment not previously described (V delta 3), and the delta chain junctional sequences formed a discrete subpopulation compared with those previously reported.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loh, E Y -- Elliott, J F -- Cwirla, S -- Lanier, L L -- Davis, M M -- New York, N.Y. -- Science. 1989 Jan 13;243(4888):217-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Medicine and Microbiology and Immunology, Stanford University School of Medicine, CA 94305-5402.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2463672" target="_blank"〉PubMed〈/a〉

    Recombinant 47-kilodalton cytosol factor restores NADPH oxidase in chronic granulomatous disease (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-07-28
    Description: A 47-kilodalton neutrophil cytosol factor (NCF-47k), required for activation of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase superoxide (O2-.) production, is absent in most patients with autosomal recessive chronic granulomatous disease (AR-CGD). NCF-47k cDNAs were cloned from an expression library. The largest clone predicted a 41.9-kD protein that contained an arginine and serine-rich COOH-terminal domain with potential protein kinase C phosphorylation sites. A 33-amino acid segment of NCF-47k shared 49% identity with ras p21 guanosine triphosphatase activating protein. Recombinant NCF-47k restored O2-. -producing activity to AR-CGD neutrophil cytosol in a cell-free assay. Production of active recombinant NCF-47k will enable functional regions of this molecule to be mapped.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lomax, K J -- Leto, T L -- Nunoi, H -- Gallin, J I -- Malech, H L -- New York, N.Y. -- Science. 1989 Jul 28;245(4916):409-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Bacterial Diseases Section, National Institute of Allergy and Infectious Diseases, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2547247" target="_blank"〉PubMed〈/a〉

    Correct folding of circularly permuted variants of a beta alpha barrel enzyme in vivo (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-01-13
    Description: An important question in protein folding is whether the natural amino and carboxyl termini and the given order of secondary structure segments are critical to the stability and to the folding pathway of proteins. Here it is shown that two circularly permuted versions of the gene of a single-domain beta alpha barrel enzyme can be expressed in Escherichia coli. The variants are enzymically active and are practically indistinguishable from the original enzyme by several structural and spectroscopic criteria, despite the creation of new termini and the cleavage of a surface loop. This novel genetic approach should be useful for protein folding studies both in vitro and in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Luger, K -- Hommel, U -- Herold, M -- Hofsteenge, J -- Kirschner, K -- New York, N.Y. -- Science. 1989 Jan 13;243(4888):206-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Abteilung Biophysikalische Chemie, Universitat Basel, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2643160" target="_blank"〉PubMed〈/a〉

    Cloning and sequencing of porcine LH-hCG receptor cDNA: variants lacking transmembrane domain (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-08-04
    Description: Complementary DNA clones, encoding the LH-hCG (luteinizing hormone-human choriogonadotropic hormone) receptor were isolated by screening a lambda gt11 library with monoclonal antibodies. The primary structure of the protein was deduced from the DNA sequence analysis; the protein contains 696 amino acids with a putative signal peptide of 27 amino acids. Hydropathy analysis suggests the existence of seven transmembrane domains that show homology with the corresponding regions of other G protein-coupled receptors. Three other types of clones corresponding to shorter proteins were observed, in which the putative transmembrane domain was absent. These probably arose through alternative splicing. RNA blot analysis showed similar patterns in testis and ovary with a major RNA of 4700 nucleotides and several minor species. The messenger RNA was expressed in COS-7 cells, yielding a protein that bound hCG with the same affinity as the testicular receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loosfelt, H -- Misrahi, M -- Atger, M -- Salesse, R -- Vu Hai-Luu Thi, M T -- Jolivet, A -- Guiochon-Mantel, A -- Sar, S -- Jallal, B -- Garnier, J -- New York, N.Y. -- Science. 1989 Aug 4;245(4917):525-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut National de la Sante et de la Recherche Medicale Unite 135, Hopital de Bicetre, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2502844" target="_blank"〉PubMed〈/a〉

    Publication Date: 1989-05-26
    Description: High-frequency (tetanic) stimulation of presynaptic nerve tracts in the hippocampal region of the brain can lead to long-term synaptic potentiation (LTP). Pertussis toxin prevented the development of tetanus-induced LTP in the stratum radiatum-CA1 synaptic system of rat hippocampal slices, indicating that a guanosine triphosphate-binding protein (G protein) may be required for the initiation of LTP. This G protein may be located at a site distinct from the postsynaptic neuron (that is, in presynaptic terminals or glial cells) since maximal activation of CA1 neuronal G proteins by intracellular injection of guanosine-5'-O-(3-thiotriphosphate), a nonhydrolyzable analog of guanosine 5'-triphosphate, did not occlude LTP.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goh, J W -- Pennefather, P S -- New York, N.Y. -- Science. 1989 May 26;244(4907):980-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Faculty of Pharmacy, University of Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2543072" target="_blank"〉PubMed〈/a〉

    Preferential heterodimer formation by isolated leucine zippers from fos and jun (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-08-11
    Description: The products of the nuclear oncogenes fos and jun are known to form heterodimers that bind to DNA and modulate transcription. Both proteins contain a leucine zipper that is important for heterodimer formation. Peptides corresponding to these leucine zippers were synthesized. When mixed, these peptides preferentially form heterodimers over homodimers by at least 1000-fold. Both homodimers and the heterodimer are parallel alpha helices. The leucine zipper regions from Fos and Jun therefore correspond to autonomous helical dimerization sites that are likely to be short coiled coils, and these regions are sufficient to determine the specificity of interaction between Fos and Jun. The Fos leucine zipper forms a relatively unstable homodimer. Instability of homodimers provides a thermodynamic driving force for preferential heterodimer formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Shea, E K -- Rutkowski, R -- Stafford, W F 3rd -- Kim, P S -- RR05711/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1989 Aug 11;245(4918):646-8.〈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/2503872" target="_blank"〉PubMed〈/a〉

    Description: The tpa-1 gene mediates the action of tumor-promoting phorbol esters in the nematode Caenorhabditis elegans. A genomic fragment that constitutes a portion of the tpa-1 gene was cloned by Tc1 transposon tagging and was used as a probe to screen a nematode complementary DNA library. One of the isolated complementary DNA clones had a nucleotide sequence that predicts a polypeptide of 526 amino acids. The predicted amino acid sequence revealed that the predicted tpa-1 protein sequence is highly similar to protein kinase C molecules from various animals, including man.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tabuse, Y -- Nishiwaki, K -- Miwa, J -- New York, N.Y. -- Science. 1989 Mar 31;243(4899):1713-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Fundamental Research Laboratories, NEC Corporation, Kawasaki, Kanagawa, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2538925" target="_blank"〉PubMed〈/a〉

    A protein that binds to a cis-acting element of wheat histone genes has a leucine zipper motif (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-09-01
    Description: The structure and function of transcription factors of higher plants was studied by isolating cDNA clones encoding a wheat sequence-specific DNA binding protein. A hexameric nucleotide motif, ACGTCA, is located upstream from the TATA box of several plant histone genes. It has been suggested that this motif is essential for efficient transcription of the wheat histone H3 gene. A wheat nuclear protein, HBP-1 (histone DNA binding protein-1), which specifically binds to the hexameric motif, has previously been identified as a putative transcription factor. A cDNA clone encoding HBP-1 has been isolated on the basis of specific binding of HBP-1 to the hexameric motif. The deduced amino acid sequence indicates that HBP-1 contains the leucine zipper motif, which represents a characteristic property of several eukaryotic transcription factors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tabata, T -- Takase, H -- Takayama, S -- Mikami, K -- Nakatsuka, A -- Kawata, T -- Nakayama, T -- Iwabuchi, M -- New York, N.Y. -- Science. 1989 Sep 1;245(4921):965-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Botany, Faculty of Science, Kyoto University, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2772648" target="_blank"〉PubMed〈/a〉

    A single amino acid interchange yields reciprocal CTL specificities for HIV-1 gp160 (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-10-06
    Description: For the IIIB isolate of human immunodeficiency virus type-1 (HIV-1), the immunodominant determinant of the envelope protein gp160 for cytotoxic T lymphocytes (CTLs) of H-2d mice is in a region of high sequence variability among HIV-1 isolates. The general requirements for CTL recognition of peptide antigens and the relation of recognition requirements to the natural variation in sequence of the HIV were investigated. For this purpose, a CTL line specific for the homologous segment of the envelope from the MN isolate of HIV-1 and restricted by the same class I major histocompatibility (MHC) molecule (Dd) as the IIIB-specific CTLs was raised from mice immunized with MN-env-recombinant vaccinia virus. The IIIB-specific and MN-specific CTLs were completely non-cross-reactive. Reciprocal exchange of a single amino acid between the two peptide sequences, which differed in 6 of 15 residues, led to a complete reversal of the specificity of the peptides in sensitizing targets, such that the IIIB-specific CTLs lysed targets exposed to the singly substituted MN peptide and vice versa. These data indicate the importance of single residues in defining peptide epitopic specificity and have implications for both the effect of immune pressure on selection of viral mutants and the design of effective vaccines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takahashi, H -- Merli, S -- Putney, S D -- Houghten, R -- Moss, B -- Germain, R N -- Berzofsky, J A -- New York, N.Y. -- Science. 1989 Oct 6;246(4926):118-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Metabolism Branch, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2789433" target="_blank"〉PubMed〈/a〉

    Inescapable versus escapable shock modulates long-term potentiation in the rat hippocampus (1989)
    American Association for the Advancement of Science (AAAS)

    Description: A group of rats was trained to escape low-intensity shock in a shuttle-box test, while another group of yoked controls could not escape but was exposed to the same amount and regime of shock. After 1 week of training, long-term potentiation (LTP) was measured in vitro in hippocampal slices. Exposure to uncontrollable shock massively impaired LTP relative to exposure to the same amount and regime of controllable shock. These results provide evidence that controllability modulates plasticity at the cellular-neuronal level.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shors, T J -- Seib, T B -- Levine, S -- Thompson, R F -- HD02881/HD/NICHD NIH HHS/ -- MH11936/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1989 Apr 14;244(4901):224-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of Southern California, Los Angeles 90089.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2704997" target="_blank"〉PubMed〈/a〉

    Mouse lymph node homing receptor cDNA clone encodes a glycoprotein revealing tandem interaction domains (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-03-03
    Description: Isolation of a clone encoding the mouse lymph node homing receptor reveals a deduced protein with an unusual protein mosaic architecture, containing a separate carbohydrate-binding (lectin) domain, an epidermal growth factor-like (EGF) domain, and an extracellular precisely duplicated repeat unit, which preserves the motif seen in the homologous repeat structure of complement regulatory proteins and other proteins. The receptor molecule is potentially highly glycosylated, and contains an apparent transmembrane region. Analysis of messenger RNA transcripts reveals a predominantly lymphoid distribution in direct relation to the cell surface expression of the MEL-14 determinant, and the cDNA clone is shown to confer the MEL-14 epitope in heterologous cells. The many novel features, including ubiquitination, embodied in this single receptor molecule form the basis for numerous approaches to the study of cell-cell interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Siegelman, M H -- van de Rijn, M -- Weissman, I L -- AI09022/AI/NIAID NIH HHS/ -- OIG43551/PHS HHS/ -- New York, N.Y. -- Science. 1989 Mar 3;243(4895):1165-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Stanford University School of Medicine, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2646713" target="_blank"〉PubMed〈/a〉

    The effect of deprenyl (selegiline) on the natural history of Parkinson's disease (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-08-04
    Description: The effects of MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine), a neurotoxin that produces the symptoms of Parkinson's disease, can be fully prevented in experimental animals by inhibiting monoamine oxidase B. On the basis of this observation, a double-blind, placebo-controlled study in patients with early Parkinson's disease was initiated to determine whether deprenyl (a selective monoamine oxidase B inhibitor) would delay the need for L-dopa therapy by slowing the progression of the disease. Fifty-four patients were randomly assigned to deprenyl (10 mg/day) or placebo treatment groups and followed until L-dopa therapy was indicated or until the patient had been in the study for 3 years. Analysis of Kaplan-Meier survival curves for each group showed that deprenyl delayed the need for L-dopa therapy; the average time until L-dopa was needed was 312.1 days for patients in the placebo group and 548.9 days for patients in the deprenyl group. Disease progression, as monitored by five different assessment scales, was slowed (by 40 to 83% per year) in the deprenyl group compared to placebo. Therefore, early deprenyl therapy delays the requirement for antiparkinsonian medication, possibly by slowing progression of the disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tetrud, J W -- Langston, J W -- New York, N.Y. -- Science. 1989 Aug 4;245(4917):519-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉California Parkinson's Foundation, San Jose 95128.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2502843" target="_blank"〉PubMed〈/a〉

    Duplication, deletion, and polymorphism in the sex-determining region of the mouse Y chromosome (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-01-06
    Description: The ZFY gene in the sex-determining region of the human Y chromosome encodes a "zinc-finger" protein that may be the testis-determining factor, TDF. Although the Y chromosomes of most placental mammals carry a single homolog of ZFY, the mouse Y chromosome has two homologs, both in the sex-determining (Sxr) region. Zfy-1 alone may suffice to determine maleness; Zfy-2 is dispensable, as it was deleted in an Sxr variant that retains sex-determining function but has lost other genes. Both loci mapped near the centromere of the mouse Y chromosome. The Y chromosomes of the subspecies Mus musculus musculus and M. m. domesticus were distinguishable by a Zfy-1 restriction fragment polymorphism, which can be used to study their differing interactions with autosomal sex-determining genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mardon, G -- Mosher, R -- Disteche, C M -- Nishioka, Y -- McLaren, A -- Page, D C -- New York, N.Y. -- Science. 1989 Jan 6;243(4887):78-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute, Nine Cambridge Center, MA 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2563173" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-07-28
    Description: Two members of the hsp70 family, termed hsc70 and BiP, have been implicated in promoting protein folding and assembly processes in the cytoplasm and the lumen of the endoplasmic reticulum, respectively. Short hydrophilic (8 to 25 residues) synthetic peptides have now been tested as possible mimics of polypeptide chain substrates to help define an enzymatic basis for these activities. Both BiP and hsc70 have specific peptide binding sites. Peptide binding elicits hydrolysis of adenosine triphosphate, with the subsequent release of bound peptide.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Flynn, G C -- Chappell, T G -- Rothman, J E -- GM-25662/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jul 28;245(4916):385-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Lewis Thomas Laboratory, Princeton University, NJ 08544.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2756425" target="_blank"〉PubMed〈/a〉

    Pathological changes induced in cerebrocortical neurons by phencyclidine and related drugs (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-06-16
    Description: Phencyclidine (PCP), a dissociative anesthetic and widely abused psychotomimetic drug, and MK-801, a potent PCP receptor ligand, have neuroprotective properties stemming from their ability to antagonize the excitotoxic actions of endogenous excitatory amino acids such as glutamate and aspartate. There is growing interest in the potential application of these compounds in the treatment of neurological disorders. However, there is an apparent neurotoxic effect of PCP and related agents (MK-801, tiletamine, and ketamine), which has heretofore been overlooked: these drugs induce acute pathomorphological changes in specific populations of brain neurons when administered subcutaneously to adult rats in relatively low doses. These findings raise new questions regarding the safety of these agents in the clinical management of neurodegenerative diseases and reinforce concerns about the potential risks associated with illicit use of PCP.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olney, J W -- Labruyere, J -- Price, M T -- DA 53568/DA/NIDA NIH HHS/ -- MH 38894/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 16;244(4910):1360-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, 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/2660263" target="_blank"〉PubMed〈/a〉

    Evidence that the leucine zipper is a coiled coil (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-01-27
    Description: Recently, a hypothetical structure called a leucine zipper was proposed that defines a new class of DNA binding proteins. The common feature of these proteins is a region spanning approximately 30 amino acids that contains a periodic repeat of leucines every seven residues. A peptide corresponding to the leucine zipper region of the yeast transcriptional activator GCN4 was synthesized and characterized. This peptide associates in the micromolar concentration range to form a very stable dimer of alpha helices with a parallel orientation. Although some features of the leucine zipper model are supported by our experimental data, the peptide has the characteristics of a coiled coil.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Shea, E K -- Rutkowski, R -- Kim, P S -- New York, N.Y. -- Science. 1989 Jan 27;243(4890):538-42.〈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/2911757" target="_blank"〉PubMed〈/a〉

    A baculovirus blocks insect molting by producing ecdysteroid UDP-glucosyl transferase (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-09-08
    Description: The predicted amino acid sequence of a newly identified gene of the insect baculovirus Autographa californica nuclear polyhedrosis virus was similar to several uridine 5'-diphosphate (UDP)-glucuronosyl transferases and at least one UDP-glucosyl transferase. Genetic and biochemical studies confirmed that this gene encodes an ecdysteroid UDP-glucosyl transferase (egt). This enzyme catalyzes the transfer of glucose from UDP-glucose to ecdysteroids, which are insect molting hormones. Expression of the egt gene allowed the virus to interfere with normal insect development so that molting was blocked in infected larvae of fall armyworm (Spodoptera frugiperda).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Reilly, D R -- Miller, L K -- AI 23719/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1989 Sep 8;245(4922):1110-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomology, University of Georgia, Athens 30602.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2505387" target="_blank"〉PubMed〈/a〉
