    Publication Date: 2022-05-25
    Description: The primary objective of this publication is to share with a wider audience the valuable information and extensive dialogue that took place amongst over 140 individuals who attended the second in a series of planned workshops on the science and management of coastal landforms in Massachusetts. This workshop took place at the Woods Hole Oceanographic Institution on January 24, 2001. The individuals who attended this workshop are actively engaged in planning, managing, regulating, engineering, educating, and studying coastal landforms and their beneficial functions. This workshop titled, Can Humans & Coastal Landforms Co-exist?’, was a natural follow-up to a previous workshop, Coastal Landform Management in Massachusetts, held at WHOI October 9-10, 1997 (proceedings published as WHOI Technical Report #WHOI-98-16). The workshop had a very practical, applied focus, providing state-of-the-art scientific understanding of coastal landform function, case history management and regulation of human activities proposed on coastal landforms, a multi-faceted mock conservation commission hearing presented by practicing technical consultants and attorneys that involved all attendees acting as regulators in breakout sessions, and, at the conclusion of the workshop, an open discussion on all issues related to the science and management of coastal landforms, including future research needs.
    Description: Funding for these proceedings was provided by WHOI Sea Grant and the NOAA National Sea Grant College Program Office, Department of Commerce, under NOAA Grant No. M10-2, Woods Hole Oceanographic Institution Sea Grant Project No. NA86R60075.

    Description: There has been a massive increase in recent years of the use of lead (Pb) isotopes in attempts to better understand sources and pathways of Pb in the environment and in man or experimental animals. Unfortunately, there have been many cases where the quality of the isotopic data, especially that obtained by quadrupole inductively coupled plasma mass spectrometry (Q-ICP-MS), are questionable, resulting in questionable identification of potential sources, which, in turn, impacts study interpretation and conclusions. We present several cases where the isotopic data have compromised interpretation because of the use of only the major isotopes 208Pb/206Pb and 207Pb/206Pb, or their graphing in other combinations. We also present some examples comparing high precision data from thermal ionization (TIMS) or multi-collector plasma mass spectrometry (MC-ICP-MS) to illustrate the deficiency in the Q-ICP-MS data. In addition, we present cases where Pb isotopic ratios measured on Q-ICP-MS are virtually impossible for terrestrial samples. We also evaluate the Pb isotopic data for rat studies, which had concluded that Pb isotopic fractionation occurs between different organs and suggest that this notion of biological fractionation of Pb as an explanation for isotopic differences is not valid. Overall, the brief review of these case studies shows that Q-ICP-MS as commonly practiced is not a suitable technique for precise and accurate Pb isotopic analysis in the environment and health fields

    The compositional distribution of coding sequences and DNA molecules in humans and murids (1988)
    Springer
    Journal of molecular evolution 27 (1988), S. 311-320 
    Details
    ISSN: 1432-1432
    Keywords: Genome composition ; Coding sequences ; Isochores ; Humans ; Murids

    Topics: Biology
    Notes: Summary The compositional distributions of coding sequences and DNA molecules (in the 50-100-kb range) are remarkably narrower in murids (rat and mouse) compared to humans (as well as to all other mammals explored so far). In murids, both distributions begin at higher and end at lower GC values. A comparison of homologous coding sequences from murids and humans revealed that their different compositional distributions are due to differences in GC levels in all three codon positions, particularly of genes located at both ends of the distribution. In turn, these differences are responsible for differences in both codon usage and amino acids. When GC levels at first+second codon positions and third codon positions, respectively, of murid genes are plotted against corresponding GC levels of homologous human genes, linear relationships (with very high correlation coefficients and slopes of about 0.78 and 0.60, respectively) are found. This indicates a conservation of the order of GC levels in homologous genes from humans and murids. (The same comparison for mouse and rat genes indicates a conservation of GC levels of homologous genes.) A similar linear relationship was observed when plotting GC levels of corresponding DNA fractions (as obtained by density gradient centrifugation in the presence of a sequence-specific ligand) from mouse and human. These findings indicate that orderly compositional changes affecting not only coding sequences but also noncoding sequences took place since the divergence of murids. Such directional fixations of mutations point to the existence of selective pressures affecting the genome as a whole.

    Notes: Summary Distribution of glycogen particles in semithin and ultrathin sections of biopsy samples from human muscles subjected to either short- or long-term running were investigated using PAS and Periodic Acid-ThioSemiCarbazide-Silver Proteinate (PA-TSC-SP) staining methods. Glycogen particles were predominantly found immediately under the sarcolemma or aligned along the myofibrillar Iband. After long-term exhaustive exercise type-1 fibers with a few or no glycogen particles in the core of the fibers were frequently observed. The subsarcolemmal glycogen stores of these “depleted” type-1 fibers were about three times as large as after exhaustive short-time exercise. Another indication of utilization of subsarcolemmal glycogen stores during anaerobic exercise was that many particles displayed a pale, rudimentary shape. This observation suggests fragmental metabolization of glycogen. Thus, depending on type of exercise and type of fiber differential and sequential glycogen utilization patterns can be observed.

    Two forms of autosomal chronic granulomatous disease lack distinct neutrophil cytosol factors (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-12-02
    Description: Chronic granulomatous diseases of childhood (CGD) are a group of disorders of phagocytic cell superoxide (O2.-) production (respiratory burst). Anion exchange chromatography separated from normal neutrophil cytosol a 47-kilodalton neutrophil cytosol factor, NCF-1, that restored activity to defective neutrophil cytosol from most patients with autosomally inherited CGD in a cell-free O2.--generating system. A 65-kilodalton factor, NCF-2, restored activity to defective neutrophil cytosol from one patient with autosomal CGD. NCF-1, NCF-2, and a third cytosol fraction, NCF-3, were inactive alone or in pairs, but together replaced unfractionated cytosol in cell-free O2.- generation. Neutrophils deficient in NCF-1, but not NCF-2, did not phosphorylate the 47-kilodalton protein. It is proposed that NCF-1, NCF-2, and NCF-3 are essential for generation of O2.- by phagocytic cells and that genetic abnormalities of these cytosol components can result in the CGD phenotype.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nunoi, H -- Rotrosen, D -- Gallin, J I -- Malech, H L -- New York, N.Y. -- Science. 1988 Dec 2;242(4883):1298-301.〈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/2848319" target="_blank"〉PubMed〈/a〉

    Transcription factor OTF-1 is functionally identical to the DNA replication factor NF-III (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-09-02
    Description: Octamer transcription factor-1 (OTF-1) and nuclear factor III (NF-III) are sequence-specific DNA binding proteins that activate transcription and DNA replication, respectively. It is shown here that OTF-1 is physically and biologically indistinguishable from NF-III. This conclusion is based on the following observations. First, the two proteins have identical mobilities by SDS-polyacrylamide gel electrophoresis. Second, OTF-1 binds to the adenovirus origin of DNA replication at the same site and with the same affinity as NF-III. Third, OTF-1 can substitute for NF-III in activating the initiation of adenovirus DNA replication in vitro. Fourth, the ability of OTF-1 to stimulate viral DNA replication is dependent on the presence of an intact NF-III binding site within the origin of replication. Fifth, NF-III can substitute for OTF-1 in activating in vitro transcription from the human histone H2b promoter. These data suggest the possibility that NF-III/OTF-1 is a protein that functions in both cellular DNA replication and transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Neill, E A -- Fletcher, C -- Burrow, C R -- Heintz, N -- Roeder, R G -- Kelly, T J -- CA16519/CA/NCI NIH HHS/ -- CA42567/CA/NCI NIH HHS/ -- R0IGM32544/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1988 Sep 2;241(4870):1210-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology and Genetics, Johns Hopkins University School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3413485" target="_blank"〉PubMed〈/a〉

    Amyloid protein precursor messenger RNAs: differential expression in Alzheimer's disease (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-08-26
    Description: In situ hybridization was used to assess total amyloid protein precursor (APP) messenger RNA and the subset of APP mRNA containing the Kunitz protease inhibitor (KPI) insert in 11 Alzheimer's disease (AD) and 7 control brains. In AD, a significant twofold increase was observed in total APP mRNA in nucleus basalis and locus ceruleus neurons but not in hippocampal subicular neurons, neurons of the basis pontis, or occipital cortical neurons. The increase in total APP mRNA in locus ceruleus and nucleus basalis neurons was due exclusively to an increase in APP mRNA lacking the KPI domain. These findings suggest that increased production of APP lacking the KPI domain in nucleus basalis and locus ceruleus neurons may play an important role in the deposition of cerebral amyloid that occurs in AD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Palmert, M R -- Golde, T E -- Cohen, M L -- Kovacs, D M -- Tanzi, R E -- Gusella, J F -- Usiak, M F -- Younkin, L H -- Younkin, S G -- 5T32GM07250/GM/NIGMS NIH HHS/ -- AG06656/AG/NIA NIH HHS/ -- MH43444/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1988 Aug 26;241(4869):1080-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neuropathology, Case Western Reserve University, School of Medicine, Cleveland, OH 44106.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2457949" target="_blank"〉PubMed〈/a〉

    Assembly of functional U1 and U2 human-amphibian hybrid snRNPs in Xenopus laevis oocytes (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-09-09
    Description: Oligonucleotides complementary to regions of U1 and U2 small nuclear RNAs (snRNAs), when injected into Xenopus laevis oocytes, rapidly induced the specific degradation of U1 and U2 snRNAs, respectively, and then themselves were degraded. After such treatment, splicing of simian virus 40 (SV40) late pre-mRNA transcribed from microinjected viral DNA was blocked in oocytes. If before introduction of SV40 DNA into oocytes HeLa cell U1 or U2 snRNAs were injected and allowed to assemble into small nuclear ribonucleoprotein particle (snRNP)-like complexes, SV40 late RNA was as efficiently spliced as in oocytes that did not receive U1 or U2 oligonucleotides. This demonstrates that oocytes can form fully functional hybrid U1 and U2 snRNPs consisting of human snRNA and amphibian proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pan, Z Q -- Prives, C -- CA33620/CA/NCI NIH HHS/ -- CA46121/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1988 Sep 9;241(4871):1328-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Columbia University, New York, NY 10027.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2970672" target="_blank"〉PubMed〈/a〉

    DNA amplification for direct detection of HIV-1 in DNA of peripheral blood mononuclear cells (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-01-15
    Description: By means of a selective DNA amplification technique called polymerase chain reaction, proviral sequences of the human immunodeficiency virus (HIV-1) were identified directly in DNA isolated from peripheral blood mononuclear cells (PBMCs) of persons seropositive but not in DNA isolated from PBMCs of persons seronegative for the virus. Primer pairs from multiple regions of the HIV-1 genome were used to achieve maximum sensitivity of provirus detection. HIV-1 sequences were detected in 100% of DNA specimens from seropositive, homosexual men from whom the virus was isolated by coculture, but in none of the DNA specimens from a control group of seronegative, virus culture-negative persons. However, HIV-1 sequences were detected in 64% of DNA specimens from seropositive, virus culture-negative homosexual men. This method of DNA amplification made it possible to obtain results within 3 days, whereas virus isolation takes up to 3 to 4 weeks. The method may therefore be used to complement or replace virus isolation as a routine means of determining HIV-1 infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ou, C Y -- Kwok, S -- Mitchell, S W -- Mack, D H -- Sninsky, J J -- Krebs, J W -- Feorino, P -- Warfield, D -- Schochetman, G -- New York, N.Y. -- Science. 1988 Jan 15;239(4837):295-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Infectious Diseases, Centers for Disease Control, Atlanta, GA 30333.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3336784" target="_blank"〉PubMed〈/a〉

    AIDS: an international perspective (1988)

    Details
    Publication Date: 1988-02-05
    Description: The acquired immunodeficiency syndrome (AIDS) and infection with the human immunodeficiency virus type 1 (HIV-1) constitute a worldwide public health problem. Whereas in Europe and in most of the Americas transmission of HIV-1 has occurred predominantly among homosexual men and intravenous drug abusers, in Africa a distinct epidemiologic pattern has emerged that indicates that HIV-1 infection is mainly heterosexually acquired. Heterosexual transmission appears to be increasing in some parts of Latin America and the Caribbean, and possibly in the United States. In addition to HIV-1, at least one other human retrovirus, namely HIV-2, has been implicated as a cause of AIDS in Africa and Europe. Factors that influence heterosexual transmission of HIV-1 include genital ulcerations, early or late stages of HIV-1 infection in the index case, and possibly oral contraception and immune activation. The rate of perinatal transmission is enhanced when the mother's illness is more advanced. AIDS and HIV-1 infection may have a significant impact not only on public health, but also on the demography and socioeconomic conditions of some developing countries. Programs for the prevention and control of AIDS should be an immediate priority in all countries.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Piot, P -- Plummer, F A -- Mhalu, F S -- Lamboray, J L -- Chin, J -- Mann, J M -- New York, N.Y. -- Science. 1988 Feb 5;239(4840):573-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, Institute of Tropical Medicine, Antwerp, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3277271" target="_blank"〉PubMed〈/a〉

    The brain in AIDS: central nervous system HIV-1 infection and AIDS dementia complex (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-02-05
    Description: Infection with human immunodeficiency virus type 1 (HIV-1) is frequently complicated in its late stages by the AIDS dementia complex, a neurological syndrome characterized by abnormalities in cognition, motor performance, and behavior. This dementia is due partially or wholly to a direct effect of the virus on the brain rather than to opportunistic infection, but its pathogenesis is not well understood. Productive HIV-1 brain infection is detected only in a subset of patients and is confined largely or exclusively to macrophages, microglia, and derivative multinucleated cells that are formed by virus-induced cell fusion. Absence of cytolytic infection of neurons, oligodentrocytes, and astrocytes has focused attention on the possible role of indirect mechanisms of brain dysfunction related to either virus or cell-coded toxins. Delayed development of the AIDS dementia complex, despite both early exposure of the nervous system to HIV-1 and chronic leptomeningeal infection, indicates that although this virus is "neurotropic," it is relatively nonpathogenic for the brain in the absence of immunosuppression. Within the context of the permissive effect of immunosuppression, genetic changes in HIV-1 may underlie the neuropathological heterogeneity of the AIDS dementia complex and its relatively independent course in relation to the systemic manifestations of AIDS noted in some patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Price, R W -- Brew, B -- Sidtis, J -- Rosenblum, M -- Scheck, A C -- Cleary, P -- NS-19048/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1988 Feb 5;239(4840):586-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Memorial Hospital, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3277272" target="_blank"〉PubMed〈/a〉

    Description: The alpha helix, first proposed by Pauling and co-workers, is a hallmark of protein structure, and much effort has been directed toward understanding which sequences can form helices. The helix hypothesis, introduced here, provides a tentative answer to this question. The hypothesis states that a necessary condition for helix formation is the presence of residues flanking the helix termini whose side chains can form hydrogen bonds with the initial four-helix greater than N-H groups and final four-helix greater than C-O groups; these eight groups would otherwise lack intrahelical partners. This simple hypothesis implies the existence of a stereochemical code in which certain sequences have the hydrogen-bonding capacity to function as helix boundaries and thereby enable the helix to form autonomously. The three-dimensional structure of a protein is a consequence of the genetic code, but the rules relating sequence to structure are still unknown. The ensuing analysis supports the idea that a stereochemical code for the alpha helix resides in its boundary residues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Presta, L G -- Rose, G D -- AG 06084/AG/NIA NIH HHS/ -- GM 29458/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1988 Jun 17;240(4859):1632-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Chemistry, Hershey Medical Center, Pennsylvania State University, Hershey 17033.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2837824" target="_blank"〉PubMed〈/a〉

    Transient expression shows ligand gating and allosteric potentiation of GABAA receptor subunits (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-12-02
    Description: Human gamma-aminobutyric acid A (GABAA) receptor subunits were expressed transiently in cultured mammalian cells. This expression system allows the simultaneous characterization of ligand-gated ion channels by electrophysiology and by pharmacology. Thus, coexpression of the alpha and beta subunits of the GABAA receptor generated GABA-gated chloride channels and binding sites for GABAA receptor ligands. Channels consisting of only alpha or beta subunits could also be detected. These homomeric channels formed with reduced efficiencies compared to the heteromeric receptors. Both of these homomeric GABA-responsive channels were potentiated by barbiturate, indicating that sites for both ligand-gating and allosteric potentiation are present on receptors assembled from either subunit.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pritchett, D B -- Sontheimer, H -- Gorman, C M -- Kettenmann, H -- Seeburg, P H -- Schofield, P R -- New York, N.Y. -- Science. 1988 Dec 2;242(4883):1306-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Neuroendocrinology, ZMBH, University of Heidelberg, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2848320" target="_blank"〉PubMed〈/a〉

    Binding of a cytosolic protein to the iron-responsive element of human ferritin messenger RNA (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-09-02
    Description: The human ferritin H chain messenger RNA contains a specific iron-responsive element (IRE) in its 5' untranslated region, which mediates regulation by iron of ferritin translation. An RNA gel retardation assay was used to demonstrate the affinity of a specific cytosolic binding protein for the IRE. A single-base deletion in the IRE eliminated both the interaction of the cytoplasmic protein with the IRE and translational regulation. Thus, the regulatory potential of the IRE correlates with its capacity to specifically interact with proteins. Titration curves of binding activity after treatment of cells with an iron chelator suggest that the factor acts as a repressor of ferritin translation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rouault, T A -- Hentze, M W -- Caughman, S W -- Harford, J B -- Klausner, R D -- New York, N.Y. -- Science. 1988 Sep 2;241(4870):1207-10.〈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/3413484" target="_blank"〉PubMed〈/a〉

    Site-directed mutagenesis of two trans-regulatory genes (tat-III,trs) of HIV-1 (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-02-19
    Description: Point mutations were introduced into the overlapping trans-regulatory genes (tat-III and trs) of human immunodeficiency virus type 1 (HIV-1), and the mutants were evaluated for virus expression. The results showed that tat-III has a positive transacting role and is required for transcriptional activation. A chain terminating mutation early in the trs gene resulted in an increase in transcription of viral messenger RNA as measured by nuclear transcription experiments, but only one major species of viral messenger RNA (1.8 kilobases) was detected, and little or no viral structural proteins were made. Thus, the trs gene product is essential for expression of virus structural proteins but, at the same time, may have a negative trans-regulatory role in transcription. Cotransfection of the point mutant proviruses defective in tat or trs with each other or with a complementary DNA clone containing tat and trs sequences restored the normal transcription pattern and subsequent virus production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sadaie, M R -- Benter, T -- Wong-Staal, F -- New York, N.Y. -- Science. 1988 Feb 19;239(4842):910-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Tumor Cell Biology, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3277284" target="_blank"〉PubMed〈/a〉

    Description: Peroxisomes are apparently missing in Zellweger syndrome; nevertheless, some of the integral membrane proteins of the organelle are present. Their distribution was studied by immunofluorescence microscopy. In control fibroblasts, peroxisomes appeared as small dots. In Zellweger fibroblasts, the peroxisomal membrane proteins were located in unusual empty membrane structures of larger size. These results suggest that the primary defect in this disease may be in the mechanism for import of matrix proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Santos, M J -- Imanaka, T -- Shio, H -- Small, G M -- Lazarow, P B -- AM19394/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1988 Mar 25;239(4847):1536-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Rockefeller University, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3281254" target="_blank"〉PubMed〈/a〉

    Absence of linkage of chromosome 21q21 markers to familial Alzheimer's disease (1988)

    Publication Date: 1988-09-16
    Description: Alzheimer's disease is the most common form of dementia among the elderly population. Although the etiology is unknown, inheritance plays a role in the pathogenesis of the disease. Recent work indicates that an autosomal dominant gene for Alzheimer's disease is located on chromosome 21 at band q21. In the present study of a group of autopsy-documented kindreds, no evidence for linkage was found between familial Alzheimer's disease (FAD) and chromosome 21q21 markers (D21S1/D21S72 and the amyloid beta gene). Linkage to the D21S1/D21S72 locus was excluded at recombination fractions (theta) up to 0.17. Linkage to the amyloid gene was excluded at theta = 0.10. Apparent recombinants were noted in two families for the amyloid gene and in five families for the D21S1/D21S72 locus. These data indicate that FAD is genetically heterogeneous.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schellenberg, G D -- Bird, T D -- Wijsman, E M -- Moore, D K -- Boehnke, M -- Bryant, E M -- Lampe, T H -- Nochlin, D -- Sumi, S M -- Deeb, S S -- AG 00057/AG/NIA NIH HHS/ -- AG 05136/AG/NIA NIH HHS/ -- GM 15253/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1988 Sep 16;241(4872):1507-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neurology, University of Washington, Seattle 98195.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3420406" target="_blank"〉PubMed〈/a〉

    Description: Recent reports of stratospheric ozone depletion have prompted concerns about the levels of solar ultraviolet radiation that reach the earth's surface. Since 1974 a network of ground-level monitoring stations in the United States has tracked measurements of biologically effective ultraviolet radiation (UVB, 290 to 330 nanometers). The fact that no increases of UVB have been detected at ground levels from 1974 to 1985 suggests that meteorological, climatic, and environmental factors in the troposphere may play a greater role in attenuating UVB radiation than was previously suspected.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scotto, J -- Cotton, G -- Urbach, F -- Berger, D -- Fears, T -- New York, N.Y. -- Science. 1988 Feb 12;239(4841 Pt 1):762-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biostatistics Branch, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3340857" target="_blank"〉PubMed〈/a〉

    Publication Date: 1988-02-26
    Description: The inheritance of particular alleles of major histocompatibility complex class II genes increases the risk for various human autoimmune diseases; however, only a small percentage of individuals having an allele associated with susceptibility develop disease. The identification of allelic variants more precisely correlated with disease susceptibility would greatly facilitate clinical screening and diagnosis. Oligonucleotide-primed gene amplification in vitro was used to determine the nucleotide sequence of a class II variant found almost exclusively in patients with the autoimmune skin disease pemphigus vulgaris. In addition to clinical implications, the disease-restricted distribution of this variant should provide insight into the molecular mechanisms underlying associations between diseases and HLA-class II genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sinha, A A -- Brautbar, C -- Szafer, F -- Friedmann, A -- Tzfoni, E -- Todd, J A -- Steinman, L -- McDevitt, H O -- New York, N.Y. -- Science. 1988 Feb 26;239(4843):1026-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medical Microbiology, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2894075" target="_blank"〉PubMed〈/a〉

    Cloning of a lymphoid-specific cDNA encoding a protein binding the regulatory octamer DNA motif (1988)

    Details
    Publication Date: 1988-07-29
    Description: An octamer DNA sequence plays a critical role in directing transcription of immunoglobulin genes in B lymphocytes. A new technique of direct binding of radioactive DNA was used to screen a complementary DNA expression library from the BJAB cell line in lambda gt11 phage to derive molecular cDNA clones representing a putative B lymphocyte-specific octamer binding protein. The plaques were screened with DNA containing four copies of the octamer sequence and positive phage recombinants were identified. The fusion protein produced on inducing a lysogen of one phage bound to a monomeric octamer probe. The cDNA insert from this phage hybridized to messenger RNA found in B lymphocytes, but not in most other cells. Thus, this cDNA derives from a gene (oct-2) that specifies an octamer binding protein expressed preferentially in B lymphocytes, proving that, for at least one gene, a cell-specific transcription factor exists and its amount is controlled through messenger RNA availability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Staudt, L M -- Clerc, R G -- Singh, H -- LeBowitz, J H -- Sharp, P A -- Baltimore, D -- P01-CA42063/CA/NCI NIH HHS/ -- P30-CAL4051/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1988 Jul 29;241(4865):577-80.〈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/3399892" target="_blank"〉PubMed〈/a〉

    A larger spectrum of severe HIV-1--related disease in intravenous drug users in New York City (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-11-11
    Description: Increasing mortality in intravenous (IV) drug users not reported to surveillance as acquired immunodeficiency syndrome (AIDS) has occurred in New York City coincident with the AIDS epidemic. From 1981 to 1986, narcotics-related deaths increased on average 32% per year from 492 in 1981 to 1996 in 1986. This increase included deaths from AIDS increasing from 0 to 905 and deaths from other causes, many of which were infectious diseases, increasing from 492 to 1091. Investigations of these deaths suggest a causal association with human immunodeficiency virus (HIV) infection. These deaths may represent a spectrum of HIV-related disease that has not been identified through AIDS surveillance and has resulted in a large underestimation of the impact of AIDS on IV drug users and blacks and Hispanics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stoneburner, R L -- Des Jarlais, D C -- Benezra, D -- Gorelkin, L -- Sotheran, J L -- Friedman, S R -- Schultz, S -- Marmor, M -- Mildvan, D -- Maslansky, R -- New York, N.Y. -- Science. 1988 Nov 11;242(4880):916-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉AIDS Research Unit, New York City Department of Health, NY 10013.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3187532" target="_blank"〉PubMed〈/a〉

    Cryopreservation, culture, and transplantation of human fetal mesencephalic tissue into monkeys (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-11-04
    Description: Studies in animals suggest that fetal neural grafts might restore lost neurological function in Parkinson's disease. In monkeys, such grafts survive for many months and reverse signs of parkinsonism, without attendant graft rejection. The successful and reliable application of a similar transplantation procedure to human patients, however, will require neural tissue obtained from human fetal cadavers, with demonstrated cellular identity, viability, and biological safety. In this report, human fetal neural tissue was successfully grafted into the brains of monkeys. Neural tissue was collected from human fetal cadavers after 9 to 12 weeks of gestation and cryopreserved in liquid nitrogen. Viability after up to 2 months of storage was demonstrated by cell culture and by transplantation into monkeys. Cryopreservation and storage of human fetal neural tissue would allow formation of a tissue bank. The stored cells could then be specifically tested to assure their cellular identity, viability, and bacteriological and virological safety before clinical use. The capacity to collect and maintain viable human fetal neural tissue would also facilitate research efforts to understand the development and function of the human brain and provide opportunities to study neurological diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Redmond, D E Jr -- Naftolin, F -- Collier, T J -- Leranth, C -- Robbins, R J -- Sladek, C D -- Roth, R H -- Sladek, J R Jr -- New York, N.Y. -- Science. 1988 Nov 4;242(4879):768-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, Yale University School of Medicine, New Haven, CT 06510.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2903552" target="_blank"〉PubMed〈/a〉

    Breast cancer-associated pS2 protein: synthesis and secretion by normal stomach mucosa (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-08-05
    Description: The human pS2 gene is specifically expressed under estrogen transcriptional control in a subclass of estrogen receptor-containing human breast cancer cells. The pS2 gene encodes an 84-amino acid protein that is secreted after signal peptide cleavage. The distribution of pS2 protein in normal human tissues was studied with antibodies to pS2; pS2 was specifically expressed and secreted by mucosa cells of the normal stomach antrum and body of both female and male individuals. Moreover, no estrogen receptor could be detected in these cells, indicating that pS2 gene expression is estrogen-independent in the stomach. The function of the pS2 protein in the gastrointestinal tract is unknown. However, the pS2 protein is similar in sequence to a porcine pancreatic protein that has been shown to inhibit gastrointestinal motility and gastric secretion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rio, M C -- Bellocq, J P -- Daniel, J Y -- Tomasetto, C -- Lathe, R -- Chenard, M P -- Batzenschlager, A -- Chambon, P -- New York, N.Y. -- Science. 1988 Aug 5;241(4866):705-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉CNRS et U. 184 de l'INSERM, Institut de Chimie Biologique, Faculte de Medecine, Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3041593" target="_blank"〉PubMed〈/a〉

    Measuring the accuracy of diagnostic systems (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-06-03
    Description: Diagnostic systems of several kinds are used to distinguish between two classes of events, essentially "signals" and "noise". For them, analysis in terms of the "relative operating characteristic" of signal detection theory provides a precise and valid measure of diagnostic accuracy. It is the only measure available that is uninfluenced by decision biases and prior probabilities, and it places the performances of diverse systems on a common, easily interpreted scale. Representative values of this measure are reported here for systems in medical imaging, materials testing, weather forecasting, information retrieval, polygraph lie detection, and aptitude testing. Though the measure itself is sound, the values obtained from tests of diagnostic systems often require qualification because the test data on which they are based are of unsure quality. A common set of problems in testing is faced in all fields. How well these problems are handled, or can be handled in a given field, determines the degree of confidence that can be placed in a measured value of accuracy. Some fields fare much better than others.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Swets, J A -- New York, N.Y. -- Science. 1988 Jun 3;240(4857):1285-93.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉BBN Laboratories Incorporated, Cambridge, MA 02238.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3287615" target="_blank"〉PubMed〈/a〉

    Structural rearrangement of the retinoblastoma gene in human breast carcinoma (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-10-14
    Description: Structural changes of the human retinoblastoma gene have been demonstrated previously in retinoblastoma and some clinically related tumors including osteosarcoma. Structural aberrations of the retinoblastoma locus (RB1) were observed in 25% of breast tumor cell lines studied and 7% of the primary tumors. These changes include homozygous internal deletions and total deletion of RB1; a duplication of an exon was observed in one of the cell lines. In all cases, structural changes either resulted in the absence or truncation of the RB1 transcript. No obvious defect in RB1 was detected by DNA blot analysis in primary tumors or cell lines from Wilms' tumor, cervical carcinoma, or hepatoma. These results further support the concept that the human RB1 gene has pleiotropic effects on specific types of cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉T'Ang, A -- Varley, J M -- Chakraborty, S -- Murphree, A L -- Fung, Y K -- CA44754/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1988 Oct 14;242(4876):263-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology/Oncology, Childrens Hospital of Los Angeles, CA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3175651" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-07-15
    Description: In 1979, a mass poisoning occurred in Taiwan from cooking oil contaminated by thermally degraded polychlorinated biphenyls. Because these chemicals persist in human tissue, children born to female patients after the outbreak were exposed in utero. In 1985, 117 children born to affected women and 108 unexposed controls were examined and evaluated. The exposed children were shorter and lighter than controls; they had abnormalities of gingiva, skin, nails, teeth, and lungs more frequently than did controls. The exposed children showed delay of developmental milestones, deficits on formal developmental testing, and abnormalities on behavioral assessment. These findings are most consistent with a generalized disorder of ectodermal tissue. This syndrome is one of very few documented to result from transplacental exposure to pollutant chemicals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rogan, W J -- Gladen, B C -- Hung, K L -- Koong, S L -- Shih, L Y -- Taylor, J S -- Wu, Y C -- Yang, D -- Ragan, N B -- Hsu, C C -- New York, N.Y. -- Science. 1988 Jul 15;241(4863):334-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute of Environmental Health Sciences, Research Triangle Park, NC 27709.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3133768" 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〉

    Details
    Publication Date: 1988-05-20
    Description: Class II major histocompatibility (MHC) molecules have an immunoregulatory role. These cell-surface glycoproteins present fragments of protein antigens (or peptides) to thymus-derived lymphocytes (T cells). Nucleotide sequence polymorphism in the genes that encode the class II MHC products determines the specificity of the immune response and is correlated with the development of autoimmune diseases. This study identifies certain class II polymorphic amino acid residues that are strongly associated with susceptibility to insulin-dependent diabetes mellitus, rheumatoid arthritis, and pemphigus vulgaris. These findings implicate particular class II MHC isotypes in susceptibility to each disease and suggest new prophylactic and therapeutic strategies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Todd, J A -- Acha-Orbea, H -- Bell, J I -- Chao, N -- Fronek, Z -- Jacob, C O -- McDermott, M -- Sinha, A A -- Timmerman, L -- Steinman, L -- New York, N.Y. -- Science. 1988 May 20;240(4855):1003-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medical Microbiology, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3368786" target="_blank"〉PubMed〈/a〉

    Monocyte-derived human B-cell growth factor identified as interferon-beta 2 (BSF-2, IL-6) (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-01-29
    Description: Soluble products of either Epstein-Barr virus (EBV)-infected B cells or activated monocytes promote the proliferation of EBV-infected B cells and permit their growth at low cell densities. This suggests that growth factors are important for B-cell immortalization by EBV. In this study, a monocyte-derived factor that promotes the growth of EBV-infected b cells was purified and identified as interferon-beta 2 (IFN-beta 2), which is also known as 26-kilodalton protein, B-cell differentiation factor (BSF-2), and interleukin-6 (IL-6).

    HIV-infected cells are killed by rCD4-ricin A chain (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-11-25
    Description: The gp120 envelope glycoprotein of the human immunodeficiency virus (HIV), which is expressed on the surface of many HIV-infected cells, binds to the cell surface molecule CD4. Soluble derivatives of recombinant CD4 (rCD4) that bind gp120 with high affinity are attractive vehicles for targeting a cytotoxic reagent to HIV-infected cells. Soluble rCD4 was conjugated to the active subunit of the toxin ricin. This conjugate killed HIV-infected H9 cells but was 1/1000 as toxic to uninfected H9 cells (which do not express gp120) and was not toxic to Daudi cells (which express major histocompatibility class II antigens, the putative natural ligand for cell surface CD4). Specific killing of infected cells can be blocked by rgp120, rCD4, or a monoclonal antibody to the gp120 binding site on CD4.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Till, M A -- Ghetie, V -- Gregory, T -- Patzer, E J -- Porter, J P -- Uhr, J W -- Capon, D J -- Vitetta, E S -- CA-09082/CA/NCI NIH HHS/ -- CA-28149/CA/NCI NIH HHS/ -- CA-41081/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1988 Nov 25;242(4882):1166-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, 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/2847316" target="_blank"〉PubMed〈/a〉

    Identification of a putative regulator of early T cell activation genes (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-07-08
    Description: Molecules involved in the antigen receptor-dependent regulation of early T cell activation genes were investigated with the use of functional sequences of the T cell activation-specific enhancer of interleukin-2 (IL-2). One of these sequences forms a protein complex, NFAT-1, specifically with nuclear extracts of activated T cells. This complex appeared 10 to 25 minutes before the activation of the IL-2 gene. Studies with inhibitors of protein synthesis indicated that the time of synthesis of the activator of the IL-2 gene in Jurkat T cells corresponds to the time of appearance of NFAT-1. NFAT-1, or a very similar protein, bound functional sequences of the long terminal repeat (LTR) of the human immunodeficiency virus type 1; the LTR of this virus is known to be stimulated during early T cell activation. The binding site for this complex activated a linked promoter after transfection into antigen receptor-activated T cells but not other cell types. These characteristics suggest that NFAT-1 transmits signals initiated at the T cell antigen receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shaw, J P -- Utz, P J -- Durand, D B -- Toole, J J -- Emmel, E A -- Crabtree, G R -- CA 01048/CA/NCI NIH HHS/ -- CA 39612/CA/NCI NIH HHS/ -- HL 33942/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1988 Jul 8;241(4862):202-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3260404" target="_blank"〉PubMed〈/a〉

    Retroviruses (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-06-10
    Description: First brought to scientific attention as infectious cancer-causing agents nearly 80 years ago, retroviruses are popular in contemporary biology for many reasons. (i) The virus life cycle includes several events--in particular, reverse transcription of the viral RNA genome into DNA, orderly integration of viral DNA into host chromosomes, and utilization of host mechanisms for gene expression in response to viral signals--which are broadly informative about eukaryotic cells and viruses. (ii) Retroviral oncogenesis usually depends on transduction or insertional activation of cellular genes, and isolation of those genes has provided the scientific community with many of the molecular components now implicated in the control of normal growth and in human cancer. (iii) Retroviruses include many important veterinary pathogens and two recently discovered human pathogens, the causative agents of the acquired immunodeficiency syndrome (AIDS) and adult T cell leukemia/lymphoma. (iv) Retroviruses are genetic vectors in nature and can be modified to serve as genetic vectors for both experimental and therapeutic purposes. (v) Insertion of retroviral DNA into host chromosomes can be used to mark cell lineages and to make developmental mutants. Progress in these and other areas of retrovirus-related biology has been enormous during the past two decades, but many practical and theoretical problems remain to be solved.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Varmus, H -- New York, N.Y. -- Science. 1988 Jun 10;240(4858):1427-35.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, School 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/3287617" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1988-03-25
    Description: The production of therapeutic human monoclonal antibodies by hybridoma technology has proved difficult, and this has prompted the "humanizing" of mouse monoclonal antibodies by recombinant DNA techniques. It was shown previously that the binding site for a small hapten could be grafted from the heavy-chain variable domain of a mouse antibody to that of a human myeloma protein by transplanting the hypervariable loops. It is now shown that a large binding site for a protein antigen (lysozyme) can also be transplanted from mouse to human heavy chain. The success of such constructions may be facilitated by an induced-fit mechanism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Verhoeyen, M -- Milstein, C -- Winter, G -- New York, N.Y. -- Science. 1988 Mar 25;239(4847):1534-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Laboratory of Molecular Biology, Cambridge, England.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2451287" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1988-12-23
    Description: The ras p21 GTPase-activating protein (GAP) was purified from human placental tissue. Internal amino acid sequence was obtained from this 120,000-dalton protein and, by means of this sequence, two types of complementary DNA clones were isolated and characterized. One type encoded GAP with a predicted molecular mass of 116,000 daltons and 96% identity with bovine GAP. The messenger RNA of this GAP was detected in human lung, brain, liver, leukocytes, and placenta. The second type appeared to be generated by a differential splicing mechanism and encoded a novel form of GAP with a predicted molecular mass of 100,400 daltons. This protein lacks the hydrophobic amino terminus characteristic of the larger species, but retains GAP activity. The messenger RNA of this type was abundantly expressed in placenta and in several human cell lines, but not in adult tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Trahey, M -- Wong, G -- Halenbeck, R -- Rubinfeld, B -- Martin, G A -- Ladner, M -- Long, C M -- Crosier, W J -- Watt, K -- Koths, K -- New York, N.Y. -- Science. 1988 Dec 23;242(4886):1697-700.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Cetus Corp., Emeryville, CA 94608.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3201259" target="_blank"〉PubMed〈/a〉

    Game depletion hypothesis of amazonian adaptation: data from a native community (1988)

    Details
    Publication Date: 1988-03-25
    Description: The low population densities and impermanent settlements of Amazonian Indians are often interpreted as adaptations to a fauna that offers limited protein resources and is rapidly depleted by hunting. Data spanning the 10-year life cycle of one northwestern Amazonian settlement show that variations in hunt yields result from temporal variations in peccary (Tayassu pecari and T. tajacu) kills that appear extrinsic to native population size. After 10 years, hunting success remained high and the kill rates for most prey did not suggest depletion. An array of environmental factors accounts for the incipient settlement relocation observed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vickers, W T -- 1FOL MH58552-01/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1988 Mar 25;239(4847):1521-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology and Sociology, Florida International University, Miami 33199.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3353699" target="_blank"〉PubMed〈/a〉

    Tandem array of human visual pigment genes at Xq28 (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-06-17
    Description: Unequal crossing-over within a head-to-tail tandem array of the homologous red and green visual pigment genes has been proposed to explain the observed variation in green-pigment gene number among individuals and the prevalence of red-green fusion genes among color-blind subjects. This model was tested by probing the structure of the red and green pigment loci with long-range physical mapping techniques. The loci were found to constitute a gene array with an approximately 39-kilobase repeat length. The position of the red pigment gene at the 5' edge of the array explains its lack of variation in copy number. Restriction maps of the array in four individuals who differ in gene number are consistent with a head-to-tail configuration of the genes. These results provide physical evidence in support of the model and help to explain the high incidence of color blindness in the human population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vollrath, D -- Nathans, J -- Davis, R W -- GM21891/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1988 Jun 17;240(4859):1669-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Stanford University School of Medicine, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2837827" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1988-12-02
    Description: Neutrophils kill microorganisms with oxygen radicals generated by an oxidase that uses the reduced form of nicotinamide adenine dinucleotide phosphate (NADPH) as substrate. This system requires both membrane and cytosolic components and is defective in patients with chronic granulomatous disease. A cytosolic complex capable of activating latent membrane oxidase was eluted from guanosine triphosphate-agarose and was used to raise polyclonal antiserum that recognized 47- and 67-kilodalton proteins. These proteins were restricted to the cytosol of myeloid cells. Both proteins were associated with NADPH oxidase-activating capacity when neutrophil cytosol was purified on nucleotide affinity matrices or molecular sizing columns. Neutrophils from patients with two different forms of autosomal chronic granulomatous disease lacked either the 47- or 67-kilodalton protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Volpp, B D -- Nauseef, W M -- Clark, R A -- AI 20866/AI/NIAID NIH HHS/ -- DM 01295/PHS HHS/ -- I01 BX000513/BX/BLRD VA/ -- R01 AI020866/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1988 Dec 2;242(4883):1295-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of Iowa, College of Medicine, Iowa City.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2848318" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details

    Description: Proteins undergo a series of nonenzymatic reactions with glucose over time to form advanced glycosylation end products (AGEs). Macrophages have a receptor that recognizes the AGE moiety and mediates the uptake and degradation of AGE proteins. This removal process is associated with the production and secretion of cachectin (tumor necrosis factor) and interleukin-1, two cytokines with diverse and seemingly paradoxical biological activities. The localized release and action of these cytokines could account for the coordinated removal and replacement of senescent extracellular matrix components in normal tissue homeostasis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vlassara, H -- Brownlee, M -- Manogue, K R -- Dinarello, C A -- Pasagian, A -- R01-AI15674/AI/NIAID NIH HHS/ -- R01-AM19655/AM/NIADDK NIH HHS/ -- R01-AM33861/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1988 Jun 10;240(4858):1546-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Medical Biochemistry, Rockefeller University, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3259727" target="_blank"〉PubMed〈/a〉

    Publication Date: 1988-04-01
    Description: Characterization of the host immune response to human immunodeficiency virus type 1 (HIV-1) is critical to the rational design of an effective AIDS vaccine. In this study, cytotoxic T lymphocytes (CTL) specific for HIV-1 reverse transcriptase (RNA-dependent DNA polymerase) were found in blood samples from HIV-1-infected individuals. CTL targets were prepared by immortalizing B cells from ten seropositive and six seronegative individuals, and then infecting these cells with recombinant vaccinia viruses containing HIV-1 genes. CTL directed against autologous B lymphoblasts expressing HIV-1 reverse transcriptase were detected in fresh blood samples from eight HIV-1 seropositive subjects, but in no seronegative controls. The effector cells were identified as major histocompatibility complex-restricted CD3+CD8+ lymphocytes. Because the HIV-1 pol gene is highly conserved among different isolates and generates both humoral and cellular immune responses, it bears consideration for inclusion in a candidate AIDS vaccine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walker, B D -- Flexner, C -- Paradis, T J -- Fuller, T C -- Hirsch, M S -- Schooley, R T -- Moss, B -- CA37461/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1988 Apr 1;240(4848):64-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Infectious Disease Unit, Massachusetts General Hospital, Harvard Medical School, Boston, MA 02114.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2451288" target="_blank"〉PubMed〈/a〉

    Mitochondrial DNA mutation associated with Leber's hereditary optic neuropathy (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-12-09
    Description: Leber's hereditary optic neuropathy is a maternally inherited disease resulting in optic nerve degeneration and cardiac dysrhythmia. A mitochondrial DNA replacement mutation was identified that correlated with this disease in multiple families. This mutation converted a highly conserved arginine to a histidine at codon 340 in the NADH dehydrogenase subunit 4 gene and eliminated an Sfa NI site, thus providing a simple diagnostic test. This finding demonstrated that a nucleotide change in a mitochondrial DNA energy production gene can result in a neurological disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wallace, D C -- Singh, G -- Lott, M T -- Hodge, J A -- Schurr, T G -- Lezza, A M -- Elsas, L J 2nd -- Nikoskelainen, E K -- NS21328/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1988 Dec 9;242(4884):1427-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Emory University School of Medicine, Atlanta, GA 30322.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3201231" target="_blank"〉PubMed〈/a〉

    Translocation and rearrangement of myeloperoxidase gene in acute promyelocytic leukemia (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-05-06
    Description: Acute promyelocytic leukemia (subtype M3) is characterized by malignant promyelocytes exhibiting an abundance of abnormally large or aberrant primary granules. Myeloperoxidase (MPO) activity of these azurophilic granules, as assessed by cytochemical staining, is unusually intense. In addition, M3 is universally associated with a chromosomal translocation, t(15;17)(q22;q11.2). In this report, the MPO gene was localized to human chromosome 17 (q12-q21), the region of the breakpoint on chromosome 17 in the t(15;17), by somatic cell hybrid analysis and in situ chromosomal hybridization. By means of MPO complementary DNA clones for in situ hybridization and Southern blot analysis, the effect of this specific translocation on the MPO gene was examined. In all cases of M3 examined, MPO is translocated to chromosome 15. Genomic blot analyses indicate rearrangement of MPO in leukemia cells of two of four cases examined. These findings suggest that MPO may be pivotal in the pathogenesis of acute promyelocytic leukemia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weil, S C -- Rosner, G L -- Reid, M S -- Chisholm, R L -- Lemons, R S -- Swanson, M S -- Carrino, J J -- Diaz, M O -- Le Beau, M M -- 1R01 CA44475/CA/NCI NIH HHS/ -- CA09273/CA/NCI NIH HHS/ -- CA16910/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1988 May 6;240(4853):790-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Northwestern University Medical Center, Chicago, IL 60611.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2896388" target="_blank"〉PubMed〈/a〉

    Alpha-2-antiplasmin: a serpin with two separate but overlapping reactive sites (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-08-05
    Description: Although the proteinase inhibitor alpha-2-antiplasmin (alpha 2AP) is known to control the activity of plasmin through rapid formation of stable complexes, it also efficiently inactivates chymotrypsin. These interactions are shown to occur at adjacent, overlapping sites so that plasmin attacks the inhibitor at an Arg364-Met365 peptide bond, while chymotrypsin interacts at a Met365-Ser366 sequence one residue downstream. Thus, a naturally occurring plasma serine proteinase inhibitor can have multiple specificities through interactions at adjacent sites. It also illustrates the potential flexibility of the reactive site loop in this class of inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Potempa, J -- Shieh, B H -- Travis, J -- New York, N.Y. -- Science. 1988 Aug 5;241(4866):699-700.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Molecular Biology, Jagiellonian University, Cracow, Poland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2456616" target="_blank"〉PubMed〈/a〉

    Description: The translational diffusion of wild-type and underglycosylated molecules of a membrane-integral glycoprotein the Ld class I major histocompatibility complex (MHC) antigen has been measured. The Ld mutant molecules, which lack one or more glycosylation sites, had larger translational diffusion coefficients, D, than did wild-type Ld molecules glycosylated at three sites. The increase in D is linear with loss of glycosylation. The highest value of D approaches that for translational diffusion of molecules constrained only by viscosity of the membrane lipid bilayer. These results indicate that the external portions of cell surface glycoproteins interact significantly with other nearby molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wier, M -- Edidin, M -- AI-14584/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1988 Oct 21;242(4877):412-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, The Johns Hopkins University, Baltimore, MD 21218.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3175663" target="_blank"〉PubMed〈/a〉

    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〉

    Specification of cerebral cortical areas (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-07-08
    Description: How the immense population of neurons that constitute the human cerebral neocortex is generated from progenitors lining the cerebral ventricle and then distributed to appropriate layers of distinctive cytoarchitectonic areas can be explained by the radial unit hypothesis. According to this hypothesis, the ependymal layer of the embryonic cerebral ventricle consists of proliferative units that provide a proto-map of prospective cytoarchitectonic areas. The output of the proliferative units is translated via glial guides to the expanding cortex in the form of ontogenetic columns, whose final number for each area can be modified through interaction with afferent input. Data obtained through various advanced neurobiological techniques, including electron microscopy, immunocytochemistry, [3H]thymidine and receptor autoradiography, retrovirus gene transfer, neural transplants, and surgical or genetic manipulation of cortical development, furnish new details about the kinetics of cell proliferation, their lineage relationships, and phenotypic expression that favor this hypothesis. The radial unit model provides a framework for understanding cerebral evolution, epigenetic regulation of the parcellation of cytoarchitectonic areas, and insight into the pathogenesis of certain cortical disorders in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rakic, P -- EY02593/EY/NEI NIH HHS/ -- NS14841/NS/NINDS NIH HHS/ -- NS22807/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1988 Jul 8;241(4862):170-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Yale University School of Medicine, New Haven, CT 06510.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3291116" target="_blank"〉PubMed〈/a〉

    Chromosome 17 deletions and p53 gene mutations in colorectal carcinomas (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-04-14
    Description: Previous studies have demonstrated that allelic deletions of the short arm of chromosome 17 occur in over 75% of colorectal carcinomas. Twenty chromosome 17p markers were used to localize the common region of deletion in these tumors to a region contained within bands 17p12 to 17p13.3. This region contains the gene for the transformation-associated protein p53. Southern and Northern blot hybridization experiments provided no evidence for gross alterations of the p53 gene or surrounding sequences. As a more rigorous test of the possibility that p53 was a target of the deletions, the p53 coding regions from two tumors were analyzed; these two tumors, like most colorectal carcinomas, had allelic deletions of chromosome 17p and expressed considerable amounts of p53 messenger RNA from the remaining allele. The remaining p53 allele was mutated in both tumors, with an alanine substituted for valine at codon 143 of one tumor and a histidine substituted for arginine at codon 175 of the second tumor. Both mutations occurred in a highly conserved region of the p53 gene that was previously found to be mutated in murine p53 oncogenes. The data suggest that p53 gene mutations may be involved in colorectal neoplasia, perhaps through inactivation of a tumor suppressor function of the wild-type p53 gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baker, S J -- Fearon, E R -- Nigro, J M -- Hamilton, S R -- Preisinger, A C -- Jessup, J M -- vanTuinen, P -- Ledbetter, D H -- Barker, D F -- Nakamura, Y -- White, R -- Vogelstein, B -- GM07184/GM/NIGMS NIH HHS/ -- GM07309/GM/NIGMS NIH HHS/ -- HD20619/HD/NICHD NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Apr 14;244(4901):217-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Oncology Center, Johns Hopkins University School of Medicine, Baltimore, MD 21231.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2649981" target="_blank"〉PubMed〈/a〉

    Seroprevalence and epidemiological correlates of HTLV-I infection in U.S. blood donors (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-04-29
    Description: Screening for human T-lymphotropic virus type I (HTLV-I) antibodies was performed on sera from 39,898 blood donors at eight blood centers in geographically distinct areas of the United States. Ten donors (0.025 percent) showed evidence of HTLV-I seropositivity by enzyme immunoassays; this was confirmed by protein immunoblot and radioimmunoprecipitation. Seroprevalence rates ranged from 0 to 0.10 percent at the locations sampled, with HTLV-I antibodies found predominantly in donors from the southeastern and southwestern United States. Matched case-control interviews and laboratory studies were performed on five seropositive women and two seropositive men who participated in an identity-linked collection of sera from a subset of 33,893 donors at six of the eight blood centers. Four of the women and both men are black; one woman is Caucasian. Four of the seven seropositive individuals admitted to prior intravenous drug abuse or sexual contact with an intravenous drug user. Sexual contact with native inhabitants of an HTLV-I endemic area was the only identified risk factor for one male. The distribution of HTLV-I antibodies in this U.S. blood donor sample corroborates the previously reported epidemiology of this agent and suggests that additional donor screening measures, including the testing of donated blood for HTLV-I markers, may be necessary to prevent the spread of HTLV-I to transfusion recipients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, A E -- Fang, C T -- Slamon, D J -- Poiesz, B J -- Sandler, S G -- Darr, W F 2nd -- Shulman, G -- McGowan, E I -- Douglas, D K -- Bowman, R J -- New York, N.Y. -- Science. 1988 Apr 29;240(4852):643-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉American Red Cross Jerome H.

    Description: This lecture illustrates the early stages in the planning and discovery of propranolol, an adrenaline beta-adrenergic receptor antagonist, and cimetidine, a histamine H2-receptor antagonist--the first examples of clinically useful drugs from each of these classes. The significance of selective agonists, partial agonists, and syntopic antagonists and the importance of the bioassay and the use of molar models in the drug discovery process are discussed. For the future, an outline of potential developments in hormone-receptor concepts is offered leading to the conclusion that progress may depend on improvements in bioassays and related molar modeling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Black, J -- New York, N.Y. -- Science. 1989 Aug 4;245(4917):486-93.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Analytical Pharmacology, Rayne Institute, King's College Hospital School of Medicine and Dentistry, London, United Kingdom.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2569237" target="_blank"〉PubMed〈/a〉

    Human ribosomal RNA genes: orientation of the tandem array and conservation of the 5' end (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-01-01
    Description: The multiple copies of the human ribosomal RNA genes (rDNA) are arranged as tandem repeat clusters that map to the middle of the short arms of chromosomes 13, 14, 15, 21, and 22. Concerted evolution of the gene family is thought to be mediated by interchromosomal recombination between rDNA repeat units, but such events would also result in conservation of the sequences distal to the rDNA on these five pairs of chromosomes. To test this possibility, a DNA fragment spanning the junction between rDNA and distal flanking sequence has been cloned and characterized. Restriction maps, sequence data, and gene mapping studies demonstrate that (i) the rRNA genes are transcribed in a telomere-to-centromere direction, (ii) the 5' end of the cluster and the adjacent non-rDNA sequences are conserved on the five pairs of chromosomes, and (iii) the 5' end of the cluster is positioned about 3.7 kb upstream from the transcription initiation site of the first repeat unit. The data support a model of concerted evolution by interchromosomal recombination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Worton, R G -- Sutherland, J -- Sylvester, J E -- Willard, H F -- Bodrug, S -- Dube, I -- Duff, C -- Kean, V -- Ray, P N -- Schmickel, R D -- HD-13506/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1988 Jan 1;239(4835):64-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genetics Department, Hospital for Sick Children, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3336775" target="_blank"〉PubMed〈/a〉

    Overexpression of transforming growth factor alpha in psoriatic epidermis (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-02-10
    Description: Transforming growth factor alpha (TGF-alpha) is produced by and required for the growth of epithelial cells and is angiogenic in vivo. Since epidermal hyperplasia and angiogenesis are hallmarks of psoriasis, TGF-alpha gene expression was analyzed in epidermal biopsies of normal and psoriatic skin. TGF-alpha messenger RNA and protein are much more abundant in lesional psoriatic epidermis than in normal-appearing skin of psoriatic patients or in normal epidermis. In contrast, messenger RNA levels of transforming growth factor beta 1 (TGF-beta 1), which inhibits epithelial cell growth, are not significantly different in normal, uninvolved, and lesional psoriatic epidermis. Thus, psoriatic epidermal hyperplasia may involve increased expression of a keratinocyte mitogen (TGF-alpha) rather than deficient expression of a growth inhibitor (TGF-beta 1).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Elder, J T -- Fisher, G J -- Lindquist, P B -- Bennett, G L -- Pittelkow, M R -- Coffey, R J Jr -- Ellingsworth, L -- Derynck, R -- Voorhees, J J -- 5-T32-AM07197-10/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1989 Feb 10;243(4892):811-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Dermatology, University of Michigan, Ann Arbor 48109.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2916128" 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〉

    Visuomotor coordination in reaching and locomotion (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-09-15
    Description: Locomotion and reaching have traditionally been regarded as separate motor activities. In fact, they may be closely connected both from an evolutionary and a neurophysiological viewpoint. Reaching seems to have evolved from the neural systems responsible for the active and precise positioning of the limb during locomotion; moreover, it seems to be organized in the spinal cord. The motor cortex and its corticospinal outflow are preferentially engaged when precise positioning of the limb is needed during locomotion and are also involved during reaching and active positioning of the hand near objects of interest. All of these motor activities require visuomotor coordination, and it is this coordination that could be achieved by the motor cortex and interconnected parietal and cerebellar areas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Georgopoulos, A P -- Grillner, S -- NS17413/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1989 Sep 15;245(4923):1209-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Philip Bard Laboratories for Neurophysiology, Department of Neuroscience, Johns Hopkins University, School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2675307" target="_blank"〉PubMed〈/a〉

    Description: Host cell factors act together with regulatory genes of the human immunodeficiency virus (HIV) to control virus production. Human-Chinese hamster ovary hybrid cell clones were used to probe for human chromosomes involved in regulating HIV gene expression. DNA transfection experiments showed that 4 of 18 clones had high levels of HIV gene expression measured by both extracellular virus production and transactivation of the HIV long terminal repeat in the presence of the trans-activator (tat) gene. Karyotype analyses revealed a 94% concordance (17/18) between human chromosome 12 and HIV gene expression. Other chromosomes had an 11 to 72% concordance with virus production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hart, C E -- Ou, C Y -- Galphin, J C -- Moore, J -- Bacheler, L T -- Wasmuth, J J -- Petteway, S R Jr -- Schochetman, G -- New York, N.Y. -- Science. 1989 Oct 27;246(4929):488-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centers for Disease Control, Atlanta, GA 30333.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2683071" target="_blank"〉PubMed〈/a〉

    Kappa B-specific DNA binding proteins: role in the regulation of human interleukin-2 gene expression (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-04-28
    Description: Transcriptional activation of the human interleukin-2 (IL-2) gene, like induction of the IL-2 receptor alpha (IL-2R alpha) gene and the type 1 human immunodeficiency virus (HIV-1), is shown to be modulated by a kappa B-like enhancer element. Mutation of a kappa B core sequence identified in the IL-2 promoter (-206 to -195) partially inhibits both mitogen- and HTLV-I Tax-mediated activation of this transcription unit and blocks the specific binding of two inducible cellular factors. These kappa B-specific proteins (80 to 90 and 50 to 55 kilodaltons) similarly interact with the functional kappa B enhancer present in the IL-2R alpha promoter. These data suggest that these kappa B-specific proteins have a role in the coordinate regulation of this growth factor-growth factor receptor gene system that controls T cell proliferation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoyos, B -- Ballard, D W -- Bohnlein, E -- Siekevitz, M -- Greene, W C -- A127053-01/PHS HHS/ -- New York, N.Y. -- Science. 1989 Apr 28;244(4903):457-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mount Sinai Medical Center, Department of Microbiology, New York, NY 10029.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2497518" target="_blank"〉PubMed〈/a〉

    The economic status of the elderly (1989)

    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: The CD4 and CD8 T cell receptor accessory molecules can both be isolated from T lymphocytes in association with p56lck, a membrane-associated, cytoplasmic tyrosine protein kinase that is expressed exclusively in lymphoid cells. The enzymatic activity of p56lck may therefore be regulated by CD4 and CD8 and be important in antigen-induced T cell activation. Exposure of human T cells and some mouse T cells to the tumor promoter 12-O-tetradecanoyl phorbol-13-acetate (TPA), an activator of protein kinase C, caused the dissociation of p56lck and CD4. Activation of protein kinase C may therefore interrupt regulation of p56lck by CD4 and alter the ability of p56lck to interact with polypeptide substrates. In contrast, exposure of cells to TPA did not cause dissociation of p56lck and CD8. Regulation of p56lck by CD4 may therefore differ from regulation by CD8.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hurley, T R -- Luo, K -- Sefton, B M -- New York, N.Y. -- Science. 1989 Jul 28;245(4916):407-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Biology and Virology Laboratory, Salk Institute, San Diego, CA 92138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2787934" target="_blank"〉PubMed〈/a〉

    Cl- channels in CF: lack of activation by protein kinase C and cAMP-dependent protein kinase (1989)

    Publication Date: 1989-06-16
    Description: Secretory chloride channels can be activated by adenosine 3',5'-monophosphate (cAMP)-dependent protein kinase in normal airway epithelial cells but not in cells from individuals with cystic fibrosis (CF). In excised, inside-out patches of apical membrane of normal human airway cells and airway cells from three patients with CF, the chloride channels exhibited a characteristic outwardly rectifying current-voltage relation and depolarization-induced activation. Channels from normal tissues were activated by both cAMP-dependent protein kinase and protein kinase C. However, chloride channels from CF patients could not be activated by either kinase. Thus, gating of normal epithelial chloride channels is regulated by both cAMP-dependent protein kinase and protein kinase C, and regulation by both kinases is defective in CF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hwang, T C -- Lu, L -- Zeitlin, P L -- Gruenert, D C -- Huganir, R -- Guggino, W B -- 1-K08-HL02188/HL/NHLBI NIH HHS/ -- R01-DK 39619/DK/NIDDK NIH HHS/ -- R01-HL 40178/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 16;244(4910):1351-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, Johns Hopkins University, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2472005" target="_blank"〉PubMed〈/a〉

    Description: An airway epithelial cell line (CF/T43) was developed by infecting cultured airway epithelial cells from patients with cystic fibrosis (CF) with the pZIPneoSV(X)1/SV40T retrovirus and selecting for G418 resistance and ion transport properties. The distinctive chloride secretory phenotypes of the CF cell line CF/T43 and a normal cell line (NL/T4) were not perturbed by SV40T-induced cell transformation. Epithelial cell lines generated from CF cells with the SV40T gene can be used to test candidate CF genes and to evaluate the molecular mechanisms responsible for the CF phenotype.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jetten, A M -- Yankaskas, J R -- Stutts, M J -- Willumsen, N J -- Boucher, R C -- HL41983/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 23;244(4911):1472-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute of Environmental Health Sciences, Research Triangle Park, NC 27709.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2472008" target="_blank"〉PubMed〈/a〉

    Peptide and protein synthesis by segment synthesis-condensation (1989)
    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〉

    A model of human acute lymphoblastic leukemia in immune-deficient SCID mice (1989)

    Details
    Publication Date: 1989-12-22
    Description: A human acute lymphoblastic leukemia (ALL) cell line that was transplanted into immune-deficient SCID mice proliferated in the hematopoietic tissues, invaded various organs, and led to the death of the mice. The distribution of leukemic cells in SCID mice was similar to the course of the disease in children. A-1 cells marked with a retrovirus vector showed clonal evolution after the transplant. SCID mice that were injected with bone marrow from three patients with non-T ALL had leukemic cells in their bone marrow and spleen. This in vivo model of human leukemia is an approach to understanding leukemic growth and progression and is a novel system for testing new treatment strategies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kamel-Reid, S -- Letarte, M -- Sirard, C -- Doedens, M -- Grunberger, T -- Fulop, G -- Freedman, M H -- Phillips, R A -- Dick, J E -- New York, N.Y. -- Science. 1989 Dec 22;246(4937):1597-600.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Hospital for Sick Children, Toronto, Ontario.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2595371" target="_blank"〉PubMed〈/a〉

    V beta-specific stimulation of human T cells by staphylococcal toxins (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-05-19
    Description: The staphylococcal toxins are responsible for a number of diseases in man and other animals. Many of them have also long been known to be powerful T cell stimulants. They do not, however, stimulate all T cells. On the contrary, each toxin reacts with human T cells bearing particular V beta sequences as part of their receptors for major histocompatibility complex protein-associated antigen. The specificity of these toxins for V beta s puts them in the recently described class of superantigens and may account for the differential sensitivity of different individuals to the toxic effects of these proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kappler, J -- Kotzin, B -- Herron, L -- Gelfand, E W -- Bigler, R D -- Boylston, A -- Carrel, S -- Posnett, D N -- Choi, Y -- Marrack, P -- AI-17134/AI/NIAID NIH HHS/ -- AI-18785/AI/NIAID NIH HHS/ -- AI-22295/AI/NIAID NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 May 19;244(4906):811-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Denver, CO.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2524876" 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〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-09-08
    Description: Approximately 70 percent of the mutations in cystic fibrosis patients correspond to a specific deletion of three base pairs, which results in the loss of a phenylalanine residue at amino acid position 508 of the putative product of the cystic fibrosis gene. Extended haplotype data based on DNA markers closely linked to the putative disease gene locus suggest that the remainder of the cystic fibrosis mutant gene pool consists of multiple, different mutations. A small set of these latter mutant alleles (about 8 percent) may confer residual pancreatic exocrine function in a subgroup of patients who are pancreatic sufficient. The ability to detect mutations in the cystic fibrosis gene at the DNA level has important implications for genetic diagnosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kerem, B -- Rommens, J M -- Buchanan, J A -- Markiewicz, D -- Cox, T K -- Chakravarti, A -- Buchwald, M -- Tsui, L C -- DK34944/DK/NIDDK NIH HHS/ -- GM33771/GM/NIGMS NIH HHS/ -- HD00774/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1989 Sep 8;245(4922):1073-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Hospital for Sick Children, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2570460" target="_blank"〉PubMed〈/a〉

    Effect of antisense c-raf-1 on tumorigenicity and radiation sensitivity of a human squamous carcinoma (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-03-10
    Description: Antisense RNA-mediated inhibition of gene expression was used to investigate the biological function of the c-raf-1 gene in a radiation-resistant human squamous carcinoma cell line, SQ-20B. S1 nuclease protection assays revealed that transfection of full-length raf complementary DNA in the antisense orientation (AS) leads to a specific reduction (greater than tenfold) of steady-state levels of the endogenous c-raf-1 sense (S) transcript in SQ-20B cells. In nude mice, the malignant potential of SQ-20B cells transfected with raf (S) was significantly increased relative to that of SQ-20B cells transfected with raf (AS). SQ-20B cells containing transfected raf (S) maintained a radiation-resistant phenotype as compared to those cells harboring the AS version, which appeared to have enhanced radiation sensitivity. These data indicate that the reduced expression of endogenous c-raf-1 is sufficient to modulate the tumorigenicity and the radiation-resistant phenotype of SQ-20B cells, thus implicating c-raf-1 in a pathway important to the genesis of this type of cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kasid, U -- Pfeifer, A -- Brennan, T -- Beckett, M -- Weichselbaum, R R -- Dritschilo, A -- Mark, G E -- New York, N.Y. -- Science. 1989 Mar 10;243(4896):1354-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Radiation Medicine, Vincent T.
