    Sequential interactions of the TCR with two distinct cytoplasmic tyrosine kinases (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-02-25
    Description: The T cell antigen receptor (TCR) initiates signals by interacting with cytoplasmic protein tyrosine kinases (PTKs) through a 17-residue sequence motif [called the antigen recognition activation motif (ARAM)] that is contained in the TCR zeta and CD3 chains. TCR stimulation induces the tyrosine phosphorylation of several cellular substrates, including the ARAMs. Lck kinase activity is required for phosphorylation of two conserved tyrosine residues in an ARAM. This phosphorylation leads to the recruitment of a second cytoplasmic PTK, ZAP-70, through both of the ZAP-70 Src homology 2 domains and its phosphorylation. Thus, TCR signal transduction is initiated by the sequential interaction of two PTKs with TCR ARAMs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Iwashima, M -- Irving, B A -- van Oers, N S -- Chan, A C -- Weiss, A -- AR-20684/AR/NIAMS NIH HHS/ -- GM39553/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Feb 25;263(5150):1136-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7509083" target="_blank"〉PubMed〈/a〉

    Autoantibodies to glutamate receptor GluR3 in Rasmussen's encephalitis (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-07-29
    Description: Rasmussen's encephalitis is a progressive childhood disease of unknown cause characterized by severe epilepsy, hemiplegia, dementia, and inflammation of the brain. During efforts to raise antibodies to recombinant glutamate receptors (GluRs), behaviors typical of seizures and histopathologic features mimicking Rasmussen's encephalitis were found in two rabbits immunized with GluR3 protein. A correlation was found between the presence of Rasmussen's encephalitis and serum antibodies to GluR3 detected by protein immunoblot analysis and by immunoreactivity to transfected cells expressing GluR3. Repeated plasma exchanges in one seriously ill child transiently reduced serum titers of GluR3 antibodies, decreased seizure frequency, and improved neurologic function. Thus, GluR3 is an autoantigen in Rasmussen's encephalitis, and an autoimmune process may underlie this disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rogers, S W -- Andrews, P I -- Gahring, L C -- Whisenand, T -- Cauley, K -- Crain, B -- Hughes, T E -- Heinemann, S F -- McNamara, J O -- NS17771/NS/NINDS NIH HHS/ -- NS28709/NS/NINDS NIH HHS/ -- NS30990R29/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Jul 29;265(5172):648-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Salt Lake City Geriatric Research Education and Clinical Center, Veterans Affairs Medical Center, UT.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8036512" target="_blank"〉PubMed〈/a〉

    Transcriptional activation modulated by homopolymeric glutamine and proline stretches (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-02-11
    Description: Many transcription factors contain proline- or glutamine-rich activation domains. Here it is shown that simple homopolymeric stretches of these amino acids can activate transcription when fused to the DNA binding domain of GAL4 factor. In vitro, activity increased with polymer length, whereas in cell transfection assays maximal activity was achieved by 10 to 30 glutamines or about 10 prolines. Similar results were obtained when glutamine stretches were placed within a [GAL4]-VP16 chimeric protein. Because these stretches are encoded by rapidly evolving triplet repeats (microsatellites), they may be the main cause for modulation of transcription factor activity and thus result in subtle or overt genomic effects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gerber, H P -- Seipel, K -- Georgiev, O -- Hofferer, M -- Hug, M -- Rusconi, S -- Schaffner, W -- New York, N.Y. -- Science. 1994 Feb 11;263(5148):808-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut fur Molekularbiologie II der Universitat Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303297" target="_blank"〉PubMed〈/a〉

    The thermal grill illusion: unmasking the burn of cold pain (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-07-08
    Description: In Thunberg's thermal grill illusion, first demonstrated in 1896, a sensation of strong, often painful heat is elicited by touching interlaced warm and cool bars to the skin. Neurophysiological recordings from two classes of ascending spinothalamic tract neurons that are sensitive to innocuous or noxious cold showed differential responses to the grill. On the basis of these results, a simple model of central disinhibition, or unmasking, predicted a quantitative correspondence between grill-evoked pain and cold-evoked pain, which was verified psychophysically. This integration of pain and temperature can explain the thermal grill illusion and the burning sensation of cold pain and may also provide a basis for the cold-evoked, burning pain of the classic thalamic pain syndrome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Craig, A D -- Bushnell, M C -- DA07402/DA/NIDA NIH HHS/ -- NS25616/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jul 8;265(5169):252-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neurobiology, Barrow Neurological Institute, Phoenix, AZ 85013.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8023144" target="_blank"〉PubMed〈/a〉

    Fusion of a kinase gene, ALK, to a nucleolar protein gene, NPM, in non-Hodgkin's lymphoma (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-03-04
    Description: The 2;5 chromosomal translocation occurs in most anaplastic large-cell non-Hodgkin's lymphomas arising from activated T lymphocytes. This rearrangement was shown to fuse the NPM nucleolar phosphoprotein gene on chromosome 5q35 to a previously unidentified protein tyrosine kinase gene, ALK, on chromosome 2p23. In the predicted hybrid protein, the amino terminus of nucleophosmin (NPM) is linked to the catalytic domain of anaplastic lymphoma kinase (ALK). Expressed in the small intestine, testis, and brain but not in normal lymphoid cells, ALK shows greatest sequence similarity to the insulin receptor subfamily of kinases. Unscheduled expression of the truncated ALK may contribute to malignant transformation in these lymphomas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morris, S W -- Kirstein, M N -- Valentine, M B -- Dittmer, K G -- Shapiro, D N -- Saltman, D L -- Look, A T -- CA 21765/CA/NCI NIH HHS/ -- KO8 CA 01702/CA/NCI NIH HHS/ -- P01 CA 20180/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Mar 4;263(5151):1281-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Experimental Oncology, St. Jude Children's Research Hospital, Memphis, TN 38105.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8122112" target="_blank"〉PubMed〈/a〉

    Nitric oxide activation of poly(ADP-ribose) synthetase in neurotoxicity (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-02-04
    Description: Poly(adenosine 5'-diphosphoribose) synthetase (PARS) is a nuclear enzyme which, when activated by DNA strand breaks, adds up to 100 adenosine 5'-diphosphoribose (ADP-ribose) units to nuclear proteins such as histones and PARS itself. This activation can lead to cell death through depletion of beta-nicotinamide adenine dinucleotide (the source of ADP-ribose) and adenosine triphosphate. Nitric oxide (NO) stimulated ADP-ribosylation of PARS in rat brain. Benzamide and other derivatives, which inhibit PARS, blocked N-methyl-D-aspartate- and NO-mediated neurotoxicity with relative potencies paralleling their ability to inhibit PARS. Thus, NO appeared to elicit neurotoxicity by activating PARS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, J -- Dawson, V L -- Dawson, T M -- Snyder, S H -- DA-00074/DA/NIDA NIH HHS/ -- DA-00266/DA/NIDA NIH HHS/ -- DA-271-90-7408/DA/NIDA NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Feb 4;263(5147):687-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉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/8080500" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-02
    Description: The mammalian embryo cannot develop without the placenta. Its specialized cells (trophoblast, endoderm, and extraembryonic mesoderm) form early in development. They attach the embryo to the uterus (implantation) and form vascular connections necessary for nutrient transport. In addition, the placenta redirects maternal endocrine, immune, and metabolic functions to the embryo's advantage. These complex activities are sensitive to disruption, as shown by the high incidence of early embryonic mortality and pregnancy diseases in humans, as well as the numerous peri-implantation lethal mutations in mice. Integration of molecular and developmental approaches has recently produced insights into the molecules that control these processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cross, J C -- Werb, Z -- Fisher, S J -- HD 22210/HD/NICHD NIH HHS/ -- HD 26732/HD/NICHD NIH HHS/ -- HD 30367/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 2;266(5190):1508-18.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Samuel Lunenfeld Research Institute, Mount Sinai Hospital, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7985020" target="_blank"〉PubMed〈/a〉

The cell surface form of LT-alpha is assembled during biosynthesis as a heteromeric complex with lymphotoxin-beta (LT-beta), a type II transmembrane protein that is another member of the TNF ligand family. Secreted LT-alpha is a homotrimer that binds to distinct TNF receptors of 60 and 80 kilodaltons; however, these receptors do not recognize the major cell surface LT-alpha-LT-beta complex. A receptor specific for human LT-beta was identified, which suggests that cell surface LT may have functions that are distinct from those of secreted LT-alpha.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crowe, P D -- VanArsdale, T L -- Walter, B N -- Ware, C F -- Hession, C -- Ehrenfels, B -- Browning, J L -- Din, W S -- Goodwin, R G -- Smith, C A -- New York, N.Y. -- Science. 1994 Apr 29;264(5159):707-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biomedical Sciences, University of California, Riverside 92521.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171323" target="_blank"〉PubMed〈/a〉

    Correction of lethal intestinal defect in a mouse model of cystic fibrosis by human CFTR (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-09
    Description: Cystic fibrosis (CF) is caused by mutations in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR). A potential animal model of CF, the CFTR-/- mouse, has had limited utility because most mice die from intestinal obstruction during the first month of life. Human CFTR (hCFTR) was expressed in CFTR-/- mice under the control of the rat intestinal fatty acid-binding protein gene promoter. The mice survived and showed functional correction of ileal goblet cell and crypt cell hyperplasia and cyclic adenosine monophosphate-stimulated chloride secretion. These results support the concept that transfer of the hCFTR gene may be a useful strategy for correcting physiologic defects in patients with CF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, L -- Dey, C R -- Wert, S E -- DuVall, M D -- Frizzell, R A -- Whitsett, J A -- DK38518/DK/NIDDK NIH HHS/ -- HL49004/HL/NHLBI NIH HHS/ -- HL51832/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 9;266(5191):1705-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Children's Hospital Medical Center, Division of Pulmonary Biology, Cincinnati, OH 45229-3039.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7527588" target="_blank"〉PubMed〈/a〉

    Interaction of IL-2R beta and gamma c chains with Jak1 and Jak3: implications for XSCID and XCID (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-11
    Description: Interleukin-2 (IL-2) signaling requires the dimerization of the IL-2 receptor beta.(IL-2R beta) and common gamma (gamma c) chains. Mutations of gamma c can result in X-linked severe combined immunodeficiency (XSCID). IL-2, IL-4, IL-7 (whose receptors are known to contain gamma c), and IL-9 (whose receptor is shown here to contain gamma c) induced the tyrosine phosphorylation and activation of the Janus family tyrosine kinases Jak1 and Jak3. Jak1 and Jak3 associated with IL-2R beta and gamma c, respectively; IL-2 induced Jak3-IL-2R beta and increased Jak3-gamma c associations. Truncations of gamma c, and a gamma c, point mutation causing moderate X-linked combined immunodeficiency (XCID), decreased gamma c-Jak3 association. Thus, gamma c mutations in at least some XSCID and XCID patients prevent normal Jak3 activation, suggesting that mutations of Jak3 may result in an XSCID-like phenotype.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Russell, S M -- Johnston, J A -- Noguchi, M -- Kawamura, M -- Bacon, C M -- Friedmann, M -- Berg, M -- McVicar, D W -- Witthuhn, B A -- Silvennoinen, O -- P30 CA21765/CA/NCI NIH HHS/ -- R01 DK42932/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 11;266(5187):1042-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Immunology, National Heart, Lung, and Blood Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973658" target="_blank"〉PubMed〈/a〉

    Implications of FRA16A structure for the mechanism of chromosomal fragile site genesis (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-24
    Description: Fragile sites are chemically induced nonstaining gaps in chromosomes. Different fragile sites vary in frequency in the population and in the chemistry of their induction. DNA sequences encompassing and including the rare, autosomal, folate-sensitive fragile site, FRA16A, were isolated by positional cloning. The molecular basis of FRA16A was found to be expansion of a normally polymorphic p(CCG)n repeat. This repeat was adjacent to a CpG island that was methylated in fragile site-expressing individuals. The FRA16A locus in individuals who do not express the fragile site is not a site of DNA methylation (imprinting), which suggests that the methylation associated with fragile sites may be a consequence and not a cause of their genesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nancarrow, J K -- Kremer, E -- Holman, K -- Eyre, H -- Doggett, N A -- Le Paslier, D -- Callen, D F -- Sutherland, G R -- Richards, R I -- New York, N.Y. -- Science. 1994 Jun 24;264(5167):1938-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cytogenetics and Molecular Genetics, Women's and Children's Hospital, North Adelaide, South Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8009225" target="_blank"〉PubMed〈/a〉

    Assembly of transcriptionally active RNA polymerase I initiation factor SL1 from recombinant subunits (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-23
    Description: Initiation of ribosomal RNA synthesis by RNA polymerase I requires the promoter selectivity factor SL1, which consists of the TATA-binding protein, TBP, and three associated factors, TAFIS 110, 63, and 48. Here the in vivo and in vitro assembly of functional SL1 complexes from recombinant TAFIS and TBP are reported. Complexes containing TBP and all three TAFIS were as active in supporting transcription from the human ribosomal RNA gene promoter as endogenous SL1, whereas partial complexes without TBP did not efficiently direct transcription in vitro. These results suggest that TAFIS 110, 63, and 48, together with TBP, are necessary and sufficient to reconstitute a transcriptionally active SL1 complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zomerdijk, J C -- Beckmann, H -- Comai, L -- Tjian, R -- New York, N.Y. -- Science. 1994 Dec 23;266(5193):2015-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular and Cell Biology, University of California, Berkeley 94720-3204.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7801130" target="_blank"〉PubMed〈/a〉

    Age of the earliest known hominids in Java, Indonesia (1994)

    Details
    Publication Date: 1994-02-25
    Description: 40Ar/39Ar laser-incremental heating of hornblende separated from pumice recovered at two hominid sites in Java, Indonesia, has yielded well-defined plateaus with weighted mean ages of 1.81 +/- 0.04 and 1.66 +/- 0.04 million years ago (Ma). The hominid fossils, a juvenile calvaria of Pithecanthropus and a partial face and cranial fragments of Meganthropus, commonly considered part of the Asian Homo erectus hypodigm, are at least 0.6 million years older than fossils referred to as Homo erectus (OH-9) from Olduvai Gorge, Tanzania, and comparable in age with the oldest Koobi Fora Homo cf. erectus (Homo ergaster) in Kenya. These ages lend further credence to the view that Homo erectus may have evolved outside of Africa. If the ancestor of Homo erectus ventured out of Africa before 1.8 Ma, the dispersal would have predated the advent of the Acheulean culture at 1.4 Ma, possibly explaining the absence of these characteristic stone cleavers and hand axes in East Asia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Swisher, C C 3rd -- Curtis, G H -- Jacob, T -- Getty, A G -- Suprijo, A -- Widiasmoro -- New York, N.Y. -- Science. 1994 Feb 25;263(5150):1118-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Geochronology Center, Institute of Human Origins, Berkeley, CA 94709.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8108729" target="_blank"〉PubMed〈/a〉

    Prophylactic vaccines, risk behavior change, and the probability of eradicating HIV in San Francisco (1994)

    Details
    Publication Date: 1994-09-02
    Description: Theory is linked with data to assess the probability of eradicating human immunodeficiency virus (HIV) in San Francisco through the use of prophylactic vaccines. The necessary vaccine efficacy levels and population coverage levels for eradication are quantified. The likely impact of risk behavior changes on vaccination campaigns is assessed. The results show it is unlikely that vaccines will be able to eradicate HIV in San Francisco unless they are combined with considerable reductions in risk behaviors. Furthermore, if risk behavior increases as the result of a vaccination campaign, then vaccination could result in a perverse outcome by increasing the severity of the epidemic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blower, S M -- McLean, A R -- 1R29DA08153/DA/NIDA NIH HHS/ -- AI33831/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 2;265(5177):1451-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Epidemiology Department, School of Public Health, University of California at Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8073289" target="_blank"〉PubMed〈/a〉

    Description: Hydroxyurea, a drug widely used in therapy of several human diseases, inhibits deoxynucleotide synthesis--and, consequently, DNA synthesis--by blocking the cellular enzyme ribonucleotide reductase. Hydroxyurea inhibits human immunodeficiency virus-type 1 (HIV-1) DNA synthesis in activated peripheral blood lymphocytes by decreasing the amount of intracellular deoxynucleotides, thus suggesting that this drug has an antiviral effect. Hydroxyurea has now been shown to block HIV-1 replication in acutely infected primary human lymphocytes (quiescent and activated) and macrophages, as well as in blood cells infected in vivo obtained from individuals with acquired immunodeficiency syndrome (AIDS). The antiviral effect was achieved at nontoxic doses of hydroxyurea, lower than those currently used in human therapy. Combination of hydroxyurea with the nucleoside analog didanosine (2',3'-dideoxyinosine, or ddl) generated a synergistic inhibitory effect without increasing toxicity. In some instances, inhibition of HIV-1 by hydroxyurea was irreversible, even several weeks after suspension of drug treatment. The indirect inhibition of HIV-1 by hydroxyurea is not expected to generate high rates of escape mutants. Hydroxyurea therefore appears to be a possible candidate for AIDS therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lori, F -- Malykh, A -- Cara, A -- Sun, D -- Weinstein, J N -- Lisziewicz, J -- Gallo, R C -- New York, N.Y. -- Science. 1994 Nov 4;266(5186):801-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Tumor Cell Biology, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892-4255.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973634" target="_blank"〉PubMed〈/a〉

    Association of intestinal peptide transport with a protein related to the cadherin superfamily (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-04-15
    Description: The first step in oral absorption of many medically important peptide-based drugs is mediated by an intestinal proton-dependent peptide transporter. This transporter facilitates the oral absorption of beta-lactam antibiotics and angiotensin-converting enzyme inhibitors from the intestine into enterocytes lining the luminal wall. A monoclonal antibody that blocked uptake of cephalexin was used to identify and clone a gene that encodes an approximately 92-kilodalton membrane protein that was associated with the acquisition of peptide transport activity by transport-deficient cells. The amino acid sequence deduced from the complementary DNA sequence of the cloned gene indicated that this transport-associated protein shares several conserved structural elements with the cadherin superfamily of calcium-dependent, cell-cell adhesion proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dantzig, A H -- Hoskins, J A -- Tabas, L B -- Bright, S -- Shepard, R L -- Jenkins, I L -- Duckworth, D C -- Sportsman, J R -- Mackensen, D -- Rosteck, P R Jr -- New York, N.Y. -- Science. 1994 Apr 15;264(5157):430-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lilly Research Laboratories, Eli Lilly and Company, Indianapolis, IN 46285.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8153632" target="_blank"〉PubMed〈/a〉

    Jak-STAT pathways and transcriptional activation in response to IFNs and other extracellular signaling proteins (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-03
    Description: Through the study of transcriptional activation in response to interferon alpha (IFN-alpha) and interferon gamma (IFN-gamma), a previously unrecognized direct signal transduction pathway to the nucleus has been uncovered: IFN-receptor interaction at the cell surface leads to the activation of kinases of the Jak family that then phosphorylate substrate proteins called STATs (signal transducers and activators of transcription). The phosphorylated STAT proteins move to the nucleus, bind specific DNA elements, and direct transcription. Recognition of the molecules involved in the IFN-alpha and IFN-gamma pathway has led to discoveries that a number of STAT family members exist and that other polypeptide ligands also use the Jak-STAT molecules in signal transduction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Darnell, J E Jr -- Kerr, I M -- Stark, G R -- New York, N.Y. -- Science. 1994 Jun 3;264(5164):1415-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Cell Biology, Rockefeller University, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8197455" target="_blank"〉PubMed〈/a〉

    Publication Date: 1994-02-11
    Description: The population of the developing world is currently expanding at the unprecedented rate of more than 800 million per decade, and despite anticipated reductions in growth during the 21st century, its size is expected to increase from 4.3 billion today to 10.2 billion in 2100. Past efforts to curb this growth have almost exclusively focused on the implementation of family planning programs to provide contraceptive information, services, and supplies. These programs have been partially successful in reducing birth rates. Further investments in them will have an additional but limited impact on population growth; therefore, other policy options, in particular measures to reduce high demand for births and limit population momentum, are needed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bongaarts, J -- New York, N.Y. -- Science. 1994 Feb 11;263(5148):771-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Division, Population Council, New York, NY 10017.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303293" target="_blank"〉PubMed〈/a〉

    Regulation of melanin biosynthesis in the human epidermis by tetrahydrobiopterin (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-03-11
    Description: The participation of (6R) 5,6,7,8-tetrahydrobiopterin (6-BH4) in regulating the tyrosine supply for melanin biosynthesis was investigated by the examination of human keratinocytes, melanocytes, and epidermal suction blisters from normal human skin and from patients with the depigmentation disorder vitiligo. Cells, as well as total epidermis, contained high phenylalanine hydroxylase activities and also displayed the capacity to synthesize and recycle 6-BH4, the essential cofactor for this enzyme. In vitiligo, 4a-hydroxy-BH4 dehydratase activity was extremely low or absent, yielding an accumulation of the nonenzymatic by-product 7-tetrahydrobiopterin (7-BH4) at concentrations up to 8 x 10(-6) M in the epidermis. This by-product is a potent competitive inhibitor in the phenylalanine hydroxylase reaction with an inhibition constant of 10(-6) M. Thus, 6-BH4 seems to control melanin biosynthesis in the human epidermis, whereas 7-BH4 may initiate depigmentation in patients with vitiligo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schallreuter, K U -- Wood, J M -- Pittelkow, M R -- Gutlich, M -- Lemke, K R -- Rodl, W -- Swanson, N N -- Hitzemann, K -- Ziegler, I -- New York, N.Y. -- Science. 1994 Mar 11;263(5152):1444-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Dermatology, University of Hamburg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8128228" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1994-09-30
    Description: Nucleotide sequence information derived from DNA segments of the human and other genomes is accumulating rapidly. However, it frequently proves difficult to use such short DNA segments to identify clones in genomic libraries or fragments in blots of the whole genome or for in situ analysis of chromosomes. Oligonucleotide probes, consisting of two target-complementary segments, connected by a linker sequence, were designed. Upon recognition of the specific nucleic acid molecule the ends of the probes were joined through the action of a ligase, creating circular DNA molecules catenated to the target sequence. These probes thus provide highly specific detection with minimal background.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nilsson, M -- Malmgren, H -- Samiotaki, M -- Kwiatkowski, M -- Chowdhary, B P -- Landegren, U -- New York, N.Y. -- Science. 1994 Sep 30;265(5181):2085-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Beijer Laboratory, Department of Medical Genetics, Biomedical Center, Uppsala, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7522346" target="_blank"〉PubMed〈/a〉

    Digenic retinitis pigmentosa due to mutations at the unlinked peripherin/RDS and ROM1 loci (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-10
    Description: In spite of recent advances in identifying genes causing monogenic human disease, very little is known about the genes involved in polygenic disease. Three families were identified with mutations in the unlinked photoreceptor-specific genes ROM1 and peripherin/RDS, in which only double heterozygotes develop retinitis pigmentosa (RP). These findings indicate that the allelic and nonallelic heterogeneity known to be a feature of monogenic RP is complicated further by interactions between unlinked mutations causing digenic RP. Recognition of the inheritance pattern exemplified by these three families might facilitate the identification of other examples of digenic inheritance in human disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kajiwara, K -- Berson, E L -- Dryja, T P -- EY00169/EY/NEI NIH HHS/ -- EY08683/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 10;264(5165):1604-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Berman-Gund Laboratory for the Study of Retinal Degenerations, Harvard Medical School, Massachusetts Eye and Ear Infirmary, Boston 02114.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8202715" target="_blank"〉PubMed〈/a〉

    Prevention of T cell anergy by signaling through the gamma c chain of the IL-2 receptor (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-11
    Description: When stimulated through their antigen receptor without requisite costimulation, T cells enter a state of antigen-specific unresponsiveness termed anergy. In this study, signaling through the common gamma chain of the interleukin-2 (IL-2), IL-4, and IL-7 receptors in the presence of antigen was found to be sufficient to prevent the induction of anergy. After culture with IL-2, IL-4, or IL-7, Jak3 kinase was tyrosine-phosphorylated, which correlated with the prevention of anergy. Therefore, a signal through the common gamma chain may regulate the decision of T cells to either clonally expand or enter a state of anergy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boussiotis, V A -- Barber, D L -- Nakarai, T -- Freeman, G J -- Gribben, J G -- Bernstein, G M -- D'Andrea, A D -- Ritz, J -- Nadler, L M -- AI 35225/AI/NIAID NIH HHS/ -- CA 40216/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 11;266(5187):1039-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematologic Malignancies, Dana-Farber Cancer Institute, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973657" target="_blank"〉PubMed〈/a〉

    Gem: an induced, immediate early protein belonging to the Ras family (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-07-08
    Description: A gene encoding a 35-kilodalton guanosine triphosphate (GTP)-binding protein, Gem, was cloned from mitogen-induced human peripheral blood T cells. Gem and Rad, the product of a gene overexpressed in skeletal muscle in individuals with Type II diabetes, constitute a new family of Ras-related GTP-binding proteins. The distinct structural features of this family include the G3 GTP-binding motif, extensive amino- and carboxyl-terminal extensions beyond the Ras-related domain, and a motif that determines membrane association. Gem was transiently expressed in human peripheral blood T cells in response to mitogenic stimulation; the protein was phosphorylated on tyrosine residues and localized to the cytosolic face of the plasma membrane. Deregulated Gem expression prevented proliferation of normal and transformed 3T3 cells. These results suggest that Gem is a regulatory protein, possibly participating in receptor-mediated signal transduction at the plasma membrane.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maguire, J -- Santoro, T -- Jensen, P -- Siebenlist, U -- Yewdell, J -- Kelly, K -- New York, N.Y. -- Science. 1994 Jul 8;265(5169):241-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Pathology, 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/7912851" target="_blank"〉PubMed〈/a〉

    Requirement of human renal water channel aquaporin-2 for vasopressin-dependent concentration of urine (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-04-01
    Description: Concentration of urine in mammals is regulated by the antidiuretic hormone vasopressin. Binding of vasopressin to its V2 receptor leads to the insertion of water channels in apical membranes of principal cells in collecting ducts. In nephrogenic diabetes insipidus (NDI), the kidney fails to concentrate urine in response to vasopressin. A male patient with an autosomal recessive form of NDI was found to be a compound heterozygote for two mutations in the gene encoding aquaporin-2, a water channel. Functional expression studies in Xenopus oocytes revealed that each mutation resulted in nonfunctional water channel proteins. Thus, aquaporin-2 is essential for vasopressin-dependent concentration of urine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deen, P M -- Verdijk, M A -- Knoers, N V -- Wieringa, B -- Monnens, L A -- van Os, C H -- van Oost, B A -- New York, N.Y. -- Science. 1994 Apr 1;264(5155):92-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Physiology, University of Nijmegen, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8140421" target="_blank"〉PubMed〈/a〉

    Reconstitution of an operational MHC class II compartment in nonantigen-presenting cells (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-02
    Description: Professional antigen-presenting cells (APCs) have a distinct compartment in which class II molecules are proposed to acquire antigenic peptides. Genetic evidence suggests that human leukocyte antigen (HLA)-DM, an unusual class II molecule, participates in this process. Peptide acquisition was reconstituted in nonprofessional APCs by transfection of class II, invariant chain (li), and H-2M, the murine equivalent of DM. The H-2M heterodimer appeared in an endosomal compartment, not at the cell surface, and the localization was independent of li. The data presented show that H-2M, class II, and li are the minimally required components for efficient formation of stable class II-peptide complexes, and thus for a functional class II compartment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karlsson, L -- Peleraux, A -- Lindstedt, R -- Liljedahl, M -- Peterson, P A -- AI-26610/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 2;266(5190):1569-73.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉R.

    Description: A cytokine was identified that stimulated the proliferation of T lymphocytes, and a complementary DNA clone encoding this new T cell growth factor was isolated. The cytokine, designated interleukin-15 (IL-15), is produced by a wide variety of cells and tissues and shares many biological properties with IL-2. Monoclonal antibodies to the beta chain of the IL-2 receptor inhibited the biological activity of IL-15, and IL-15 competed for binding with IL-2, indicating that IL-15 uses components of the IL-2 receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grabstein, K H -- Eisenman, J -- Shanebeck, K -- Rauch, C -- Srinivasan, S -- Fung, V -- Beers, C -- Richardson, J -- Schoenborn, M A -- Ahdieh, M -- New York, N.Y. -- Science. 1994 May 13;264(5161):965-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Immunex Research and Development Corporation, Seattle, WA 98101.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178155" target="_blank"〉PubMed〈/a〉

    Description: The basal ganglia are neural structures within the motor and cognitive control circuits in the mammalian forebrain and are interconnected with the neocortex by multiple loops. Dysfunction in these parallel loops caused by damage to the striatum results in major defects in voluntary movement, exemplified in Parkinson's disease and Huntington's disease. These parallel loops have a distributed modular architecture resembling local expert architectures of computational learning models. During sensorimotor learning, such distributed networks may be coordinated by widely spaced striatal interneurons that acquire response properties on the basis of experienced reward.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Graybiel, A M -- Aosaki, T -- Flaherty, A W -- Kimura, M -- NEI 02866/PHS HHS/ -- NS25529/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 23;265(5180):1826-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Brain and Cognitive Science, Massachusetts Institute of Technology, Cambridge 02139.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8091209" target="_blank"〉PubMed〈/a〉

    Stimulation of RNA polymerase II elongation by chromosomal protein HMG-14 (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-08-05
    Description: The high-mobility group protein 14 (HMG-14) is a non-histone chromosomal protein that is preferentially associated with transcriptionally active chromatin. To assess the effect of HMG-14 on transcription by RNA polymerase II, in vivo-assembled chromatin with elevated amounts of HMG-14 was obtained. Here it is shown that HMG-14 enhanced transcription on chromatin templates but not on DNA templates. This protein stimulated the rate of elongation by RNA polymerase II but not the level of initiation of transcription. These findings suggest that the association of HMG-14 with nucleosomes is part of the cellular process involved in the generation of transcriptionally active chromatin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ding, H F -- Rimsky, S -- Batson, S C -- Bustin, M -- Hansen, U -- GM-36667/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Aug 5;265(5173):796-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Genetics, Dana-Farber Cancer Institute, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8047885" target="_blank"〉PubMed〈/a〉

    Lack of evidence for the dichotomy of TH1 and TH2 predominance in HIV-infected individuals (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-07-08
    Description: A switch from a T helper 1 (TH1) cytokine phenotype to a TH2 phenotype has been proposed as a critical element in the progression of human immunodeficiency virus (HIV) disease. Here, constitutive cytokine expression was analyzed in unfractionated and sorted cell populations isolated from peripheral blood and lymph nodes of HIV-infected individuals at different stages of disease. Expression of interleukin-2 (IL-2) and IL-4 was barely detectable (or undetectable) regardless of the stage of disease. CD8+ cells expressed large amounts of interferon gamma and IL-10, and the levels of these cytokines remained stably high throughout the course of infection. Furthermore, similar patterns of cytokine expression were observed after stimulation in vitro of purified CD4+ T cell populations obtained from HIV-infected individuals at different stages of disease. These results indicate that a switch from the TH1 to the TH2 cytokine phenotype does not occur during the progression of HIV disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Graziosi, C -- Pantaleo, G -- Gantt, K R -- Fortin, J P -- Demarest, J F -- Cohen, O J -- Sekaly, R P -- Fauci, A S -- New York, N.Y. -- Science. 1994 Jul 8;265(5169):248-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunoregulation, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8023143" target="_blank"〉PubMed〈/a〉

    Activation of the myogenic lineage by MEF2A, a factor that induces and cooperates with MyoD (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-18
    Description: Muscle enhancer factor-2A (MEF2A), a member of the MADS family, induced myogenic development when ectopically expressed in clones of nonmuscle cells of human clones, a function previously limited to the muscle basic helix-loop-helix (bHLH) proteins. During myogenesis, MEF2A and bHLH proteins cooperatively activate skeletal muscle genes and physically interact through the MADS domain of MEF2A and the three myogenic amino acids of the muscle bHLH proteins. Thus, skeletal myogenesis is mediated by two distinct families of mutually inducible and interactive muscle transcription factors, either of which can initiate the developmental cascade.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaushal, S -- Schneider, J W -- Nadal-Ginard, B -- Mahdavi, V -- New York, N.Y. -- Science. 1994 Nov 18;266(5188):1236-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cardiology, Children'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/7973707" target="_blank"〉PubMed〈/a〉

    Blockage of NF-kappa B signaling by selective ablation of an mRNA target by 2-5A antisense chimeras (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-08-05
    Description: Activation of 2-5A-dependent ribonuclease by 5'-phosphorylated, 2',5'-linked oligoadenylates, known as 2-5A, is one pathway of interferon action. Unaided uptake into HeLa cells of 2-5A linked to an antisense oligonucleotide resulted in the selective ablation of messenger RNA for the double-stranded RNA (dsRNA)-dependent protein kinase PKR. Similarly, purified, recombinant human 2-5A-dependent ribonuclease was induced to selectively cleave PKR messenger RNA. Cells depleted of PKR activity were unresponsive to activation of nuclear factor-kappa B (NF-kappa B) by the dsRNA poly(I):poly(C), which provides direct evidence that PKR is a transducer for the dsRNA signaling of NF-kappa B.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maran, A -- Maitra, R K -- Kumar, A -- Dong, B -- Xiao, W -- Li, G -- Williams, B R -- Torrence, P F -- Silverman, R H -- AI 28253/AI/NIAID NIH HHS/ -- AI 34039-02/AI/NIAID NIH HHS/ -- CA 44059/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Aug 5;265(5173):789-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cancer Biology, Cleveland Clinic Foundation, OH 44195.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7914032" target="_blank"〉PubMed〈/a〉

    Linkage analysis of IL4 and other chromosome 5q31.1 markers and total serum immunoglobulin E concentrations (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-05-20
    Description: Sib-pair analysis of 170 individuals from 11 Amish families revealed evidence for linkage of five markers in chromosome 5q31.1 with a gene controlling total serum immunoglobulin E (IgE) concentration. No linkage was found between these markers and specific IgE antibody concentrations. Analysis of total IgE within a subset of 128 IgE antibody-negative sib pairs confirmed evidence for linkage to 5q31.1, especially to the interleukin-4 gene (IL4). A combination of segregation and maximum likelihood analyses provided further evidence for this linkage. These analyses suggest that IL4 or a nearby gene in 5q31.1 regulates IgE production in a nonantigen-specific (noncognate) fashion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Marsh, D G -- Neely, J D -- Breazeale, D R -- Ghosh, B -- Freidhoff, L R -- Ehrlich-Kautzky, E -- Schou, C -- Krishnaswamy, G -- Beaty, T H -- 1 P41 RR03655/RR/NCRR NIH HHS/ -- AI20059/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 May 20;264(5162):1152-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Johns Hopkins Asthma and Allergy Center, School of Medicine, Baltimore, MD 21224.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178175" target="_blank"〉PubMed〈/a〉

    Gene for familial psoriasis susceptibility mapped to the distal end of human chromosome 17q (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-05-20
    Description: A gene involved in psoriasis susceptibility was localized to the distal region of human chromosome 17q as a result of a genome-wide linkage analysis with polymorphic microsatellites and eight multiply affected psoriasis kindreds. In the family which showed the strongest evidence for linkage, the recombination fraction between a psoriasis susceptibility locus and D17S784 was 0.04 with a maximum two-point lod score of 5.33. There was also evidence for genetic heterogeneity and although none of the linked families showed any association with HLA-Cw6, two unlinked families showed weak levels of association. This study demonstrates that in some families, psoriasis susceptibility is due to variation at a single major genetic locus other than the human lymphocyte antigen locus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tomfohrde, J -- Silverman, A -- Barnes, R -- Fernandez-Vina, M A -- Young, M -- Lory, D -- Morris, L -- Wuepper, K D -- Stastny, P -- Menter, A -- P01-AI2327/AI/NIAID NIH HHS/ -- R01 HL47145/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1994 May 20;264(5162):1141-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, University of Texas Southwestern Medical Center, Dallas 75235-8591.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178173" target="_blank"〉PubMed〈/a〉

    Long-term behavioral recovery in parkinsonian rats by an HSV vector expressing tyrosine hydroxylase (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-25
    Description: One therapeutic approach to treating Parkinson's disease is to convert endogenous striatal cells into levo-3,4-dihydroxyphenylalanine (L-dopa)-producing cells. A defective herpes simplex virus type 1 vector expressing human tyrosine hydroxylase was delivered into the partially denervated striatum of 6-hydroxydopamine-lesioned rats, used as a model of Parkinson's disease. Efficient behavioral and biochemical recovery was maintained for 1 year after gene transfer. Biochemical recovery included increases in both striatal tyrosine hydroxylase enzyme activity and in extracellular dopamine concentrations. Persistence of human tyrosine hydroxylase was revealed by expression of RNA and immunoreactivity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2638002/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2638002/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉During, M J -- Naegele, J R -- O'Malley, K L -- Geller, A I -- EY09749/EY/NEI NIH HHS/ -- NS06208/NS/NINDS NIH HHS/ -- NS28227/NS/NINDS NIH HHS/ -- R01 NS034025/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Nov 25;266(5189):1399-403.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Surgery, 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/7669103" target="_blank"〉PubMed〈/a〉

    Efficient neutralization of primary isolates of HIV-1 by a recombinant human monoclonal antibody (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-11
    Description: The ability of antibodies to neutralize diverse primary isolates of human immunodeficiency virus-type 1 in vitro has been questioned, with implications for the likely efficacy of vaccines. A recombinant human antibody to envelope glycoprotein gp120 was generated and used to show that primary isolates are not refractory to antibody neutralization. The recombinant antibody neutralized more than 75 percent of the primary isolates tested at concentrations that could be achieved by passive immunization, for example, to interrupt maternal-fetal transmission of virus. The broad specificity and efficacy of the antibody implies the conservation of a structural feature on gp120, which could be important in vaccine design.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burton, D R -- Pyati, J -- Koduri, R -- Sharp, S J -- Thornton, G B -- Parren, P W -- Sawyer, L S -- Hendry, R M -- Dunlop, N -- Nara, P L -- AI27742/AI/NIAID NIH HHS/ -- AI33292/AI/NIAID NIH HHS/ -- AI35168/AI/NIAID NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Nov 11;266(5187):1024-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Scripps Research Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973652" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1994-07-29
    Description: In eukaryotic cells, a multitude of RNA-binding proteins play key roles in the posttranscriptional regulation of gene expression. Characterization of these proteins has led to the identification of several RNA-binding motifs, and recent experiments have begun to illustrate how several of them bind RNA. The significance of these interactions is reflected in the recent discoveries that several human and other vertebrate genetic disorders are caused by aberrant expression of RNA-binding proteins. The major RNA-binding motifs are described and examples of how they may function are given.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burd, C G -- Dreyfuss, G -- New York, N.Y. -- Science. 1994 Jul 29;265(5172):615-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of Pennsylvania School of Medicine, Philadelphia 19104-6148.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8036511" target="_blank"〉PubMed〈/a〉

    Rapid induction of Alzheimer A beta amyloid formation by zinc (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-09-02
    Description: A beta 1-40, a major component of Alzheimer's disease cerebral amyloid, is present in the cerebrospinal fluid and remains relatively soluble at high concentrations (less than or equal to 3.7 mM). Thus, physiological factors which induce A beta amyloid formation could provide clues to the pathogenesis of the disease. It has been shown that human A beta specifically and saturably binds zinc. Here, concentrations of zinc above 300 nM rapidly destabilized human A beta 1-40 solutions, inducing tinctorial amyloid formation. However, rat A beta 1-40 binds zinc less avidly and is immune to these effects, perhaps explaining the scarcity with which these animals form cerebral A beta amyloid. These data suggest a role for cerebral zinc metabolism in the neuropathogenesis of Alzheimer's disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bush, A I -- Pettingell, W H -- Multhaup, G -- d Paradis, M -- Vonsattel, J P -- Gusella, J F -- Beyreuther, K -- Masters, C L -- Tanzi, R E -- R01 AG11899-01/AG/NIA NIH HHS/ -- R01 NS30428-03/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 2;265(5177):1464-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetics and Aging, Massachusetts General Hospital, Boston.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8073293" target="_blank"〉PubMed〈/a〉
