    Parasitic protozoa and helminths: biological and immunological challenges (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-11-24
    Description: Parasitic protozoans and helminths pose considerable medical as well as scientific challenges. Investigations of the complex and very different life cycles of these organisms, their adaptation to the obligate parasitic mode of life, and their ability to face the hostile host environment have resulted in many exciting discoveries. Invasion of host erythrocytes by plasmodial sporozoites and intact skin by schistosomal cercariae are outlined as examples of the elaborate mechanisms of parasitism. Isolation and characterization of single protective antigens or subunit vaccines from these two organisms are examined as models for vaccine development. Finally, developments in exploring gene regulation in protozoans and free and parasitic nematodes are briefly outlined.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mahmoud, A A -- New York, N.Y. -- Science. 1989 Nov 24;246(4933):1015-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, 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/2686024" target="_blank"〉PubMed〈/a〉

    Functions of sphingolipids and sphingolipid breakdown products in cellular regulation (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-01-27
    Description: The discovery that breakdown products of cellular sphingolipids are biologically active has generated interest in the role of these molecules in cell physiology and pathology. Sphingolipid breakdown products, sphingosine and lysosphingolipids, inhibit protein kinase C, a pivotal enzyme in cell regulation and signal transduction. Sphingolipids and lysosphingolipids affect significant cellular responses and exhibit antitumor promoter activities in various mammalian cells. These molecules may function as endogenous modulators of cell function and possibly as second messengers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hannun, Y A -- Bell, R M -- CA46738/CA/NCI NIH HHS/ -- GM38737/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jan 27;243(4890):500-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Duke University Medical Center, Durham, NC 27710.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2643164" target="_blank"〉PubMed〈/a〉

    Description: An article in 30 June issue (";Dangerous' liaisons in cell biology," p. 1539), which discussed the commentary in the 2 June issue of the journal Cell by Max L. Birnstiel and Meinrad Busslinger regarding the transgenic mice experiments of Corrado Spadafora and co-workers, stated that Vienna's Institute of Molecular Pathology (IMP), for which Birnstiel and Busslinger work, was seeking patents on extensions of the Spadafora experiments. On further investigation, we have learned that this is not correct. At present no applications have been applied for or granted to IMP or its parent companies Genentech and Boehringer Ingelheim. We wish to correct the record, apologize to Dr. Birnstiel and Dr. Busslinger for this misstatement, and alert our readers to their letter, which is printed in our Letters section on page 243.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Marx, J L -- New York, N.Y. -- Science. 1989 Jul 21;245(4915):252-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2526371" target="_blank"〉PubMed〈/a〉

    Tonotopic organization of the auditory cortex: pitch versus frequency representation (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-10-27
    Description: According to the place principles of the classical hearing theory, the physical entity frequency is encoded in the auditory periphery as place information (tonotopic representation), which is decoded in more central parts of the auditory system to form the subjective entity pitch. However, this relation is true only for pure-tone signals (spectral pitch); it can be quite different in the case of complex auditory stimuli (virtual pitch), thus requiring a multistage process for pitch formation. Neuromagnetic measurements showed that the tonotopic organization of the primary auditory cortex reflects the pitch rather than the frequency of the stimulus; that is, the pitch formation process must take place in subcortical regions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pantev, C -- Hoke, M -- Lutkenhoner, B -- Lehnertz, K -- New York, N.Y. -- Science. 1989 Oct 27;246(4929):486-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Experimental Audiology, University of Munster, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2814476" target="_blank"〉PubMed〈/a〉

    Point mutational inactivation of the retinoblastoma antioncogene (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-02-17
    Description: The retinoblastoma (Rb) antioncogene encodes a nuclear phosphoprotein, p105-Rb, that forms protein complexes with the adenovirus E1A and SV40 large T oncoproteins. A novel, aberrant Rb protein detected in J82 bladder carcinoma cells was not able to form a complex with E1A and was less stable than p105-Rb. By means of a rapid method for the detection of mutations in Rb mRNA, this defective Rb protein was observed to result from a single point mutation within a splice acceptor sequence in J82 genomic DNA. This mutation eliminates a single exon and 35 amino acids from its encoded protein product.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Horowitz, J M -- Yandell, D W -- Park, S H -- Canning, S -- Whyte, P -- Buchkovich, K -- Harlow, E -- Weinberg, R A -- Dryja, T P -- CA 08131/CA/NCI NIH HHS/ -- CA 13106/CA/NCI NIH HHS/ -- CA 39826/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Feb 17;243(4893):937-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Massachusetts Institute of Technology, Cambridge 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2521957" target="_blank"〉PubMed〈/a〉

    Catalytic hydrolysis of vasoactive intestinal peptide by human autoantibody (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-06-09
    Description: Vasoactive intestinal peptide (VIP) labeled with 125I, [Tyr10-125I]VIP, can be hydrolyzed by immunoglobulin G (IgG) purified from a human subject, as judged by trichloroacetic acid precipitation and reversed-phase high-performance liquid chromatography (HPLC). The hydrolytic activity was precipitated by antibody to human IgG, it was bound by immobilized protein G and showed a molecular mass close to 150 kilodaltons by gel filtration chromatography, properties similar to those of authentic IgG. The Fab fragment, prepared from IgG by papain treatment, retained the VIP hydrolytic activity of the IgG. Peptide fragments produced by treatment of VIP with the antibody fraction were purified by reversed-phase HPLC and identified by fast atom bombardment-mass spectrometry and peptide sequencing. The scissile bond in VIP deduced from these experiments was Gln16-Met17. The antibody concentration (73.4 fmol per milligram of IgG) and the Kd (0.4 nM) were computed from analysis of VIP binding under conditions that did not result in peptide hydrolysis. Analysis of the antibody-mediated VIP hydrolysis at varying concentrations of substrate suggested conformity with Michaelis-Menton kinetics (Km). The values for Km (37.9 X 10(-9) M) and the turnover number kcat (15.6 min-1) suggested relatively tight VIP binding and a moderate catalytic efficiency of the antibody.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Paul, S -- Volle, D J -- Beach, C M -- Johnson, D R -- Powell, M J -- Massey, R J -- HL 35506/HL/NHLBI NIH HHS/ -- HL 40348/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 9;244(4909):1158-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Nebraska Medical Center, Omaha 68105.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2727702" target="_blank"〉PubMed〈/a〉

    Genomic sequencing and methylation analysis by ligation mediated PCR (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-11-10
    Description: Genomic sequencing permits studies of in vivo DNA methylation and protein-DNA interactions, but its use has been limited because of the complexity of the mammalian genome. A newly developed genomic sequencing procedure in which a ligation mediated polymerase chain reaction (PCR) is used generates high quality, reproducible sequence ladders starting with only 1 microgram of uncloned mammalian DNA per reaction. Different sequence ladders can be created simultaneously by inclusion of multiple primers and visualized separately by rehybridization. Relatively little radioactivity is needed for hybridization and exposure times are short. Methylation patterns in genomic DNA are readily detectable; for example, 17 CpG dinucleotides in the 5' region of human X-linked PGK-1 (phosphoglycerate kinase 1) were found to be methylated on an inactive human X chromosome, but unmethylated on an active X chromosome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pfeifer, G P -- Steigerwald, S D -- Mueller, P R -- Wold, B -- Riggs, A D -- AG08196/AG/NIA NIH HHS/ -- GM355262BW/GM/NIGMS NIH HHS/ -- RR07003/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1989 Nov 10;246(4931):810-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Biology Section, Beckman Research Institute of the City of Hope, Duarte, CA 91010.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2814502" target="_blank"〉PubMed〈/a〉

    Type I and type II GABAA-benzodiazepine receptors produced in transfected cells (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-09-22
    Description: GABAA (gamma-aminobutyric acid A)-benzodiazepine receptors expressed in mammalian cells and assembled from one of three different alpha subunit variants (alpha 1, alpha 2, or alpha 3) in combination with a beta 1 and a gamma 2 subunit display the pharmacological properties of either type I or type II receptor subtypes. These receptors contain high-affinity binding sites for benzodiazepines. However, CL 218 872, 2-oxoquazepam, and methyl beta-carboline-3-carboxylate (beta-CCM) show a temperature-modulated selectivity for alpha 1 subunit-containing receptors. There were no significant differences in the binding of clonazepam, diazepam, Ro 15-1788, or dimethoxy-4-ethyl-beta-carboline-3-carboxylate (DMCM) to all three recombinant receptors. Receptors containing the alpha 3 subunit show greater GABA potentiation of benzodiazepine binding than receptors containing the alpha 1 or alpha 2 subunit, indicating that there are subtypes within the type II class. Thus, diversity in benzodiazepine pharmacology is generated by heterogeneity of the alpha subunit of the GABAA receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pritchett, D B -- Luddens, H -- Seeburg, P H -- New York, N.Y. -- Science. 1989 Sep 22;245(4924):1389-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Neuroendocrinology, Zentrum fur Molekulare Biologie, Universitat Heidelberg, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2551039" target="_blank"〉PubMed〈/a〉

    Interleukin-1 mitogenic activity for fibroblasts and smooth muscle cells is due to PDGF-AA (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-01-20
    Description: Both interleukin-1 (IL-1) and platelet-derived growth factor (PDGF) induce proliferation of cultured fibroblasts and smooth muscle cells. These polypeptide mediators are released by activated macrophages and other cell types in response to injury and are thought to have a role in tissue remodeling and a number of pathologic processes. Analysis of the kinetics of [3H]thymidine incorporation by cultured fibroblasts demonstrated that the response to IL-1 is delayed approximately 8 hours relative to their response to PDGF. IL-1 transiently stimulated expression of the PDGF A-chain gene, with maximum induction after approximately 2 hours. Subsequent synthesis and release of PDGF activity into the medium was detected as early as 4 hours after IL-1 stimulation, and downregulation of the binding site for the PDGF-AA isoform of PDGF followed PDGF-AA secretion. Antibodies to PDGF completely block the mitogenic response to IL-1. Therefore, the mitogenic activity of IL-1 for fibroblasts and smooth muscle cells appears to be indirect and mediated by induction of the PDGF A-chain gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raines, E W -- Dower, S K -- Ross, R -- HL-18645/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Jan 20;243(4889):393-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, University of Washington, Seattle 98195.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2783498" target="_blank"〉PubMed〈/a〉

    Identification of a zinc finger protein that binds to the sterol regulatory element (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-08-11
    Description: Cholesterol balance in mammalian cells is maintained in part by sterol-mediated repression of gene transcription for the low density lipoprotein receptor and enzymes in the cholesterol biosynthetic pathway. A promoter sequence termed the sterol regulatory element (SRE) is essential for this repression. With the use of an oligonucleotide containing the SRE to screen a human hepatoma complementary DNA expression library, a clone for a DNA binding protein was isolated that binds to the conserved SRE octanucleotide in both a sequence-specific and a single-strand--specific manner. This protein contains seven highly conserved zinc finger repeats that exhibit striking sequence similarity to retroviral nucleic acid binding proteins (NBPs). We have designated the protein "cellular NBP" (CNBP). CNBP is expressed in a wide variety of tissues, is up regulated by sterols, and exhibits binding specificity that correlates with in vivo function. These properties are consistent with a role in sterol-mediated control of transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rajavashisth, T B -- Taylor, A K -- Andalibi, A -- Svenson, K L -- Lusis, A J -- HL30568/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Aug 11;245(4918):640-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of California, Los Angeles 90024.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2562787" target="_blank"〉PubMed〈/a〉

    elk, tissue-specific ets-related genes on chromosomes X and 14 near translocation breakpoints (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-04-07
    Description: The myb-ets-containing acute leukemia virus, E26, transforms myeloblasts and erythroblasts in culture and causes a mixed erythroid and myeloid leukemia in chicks. Genes (ets-1, ets-2, and erg) with variable relatedness to the v-ets oncogene of the E26 virus have been identified, cloned, and characterized in several species. Two new members (elk-1 and elk-2) of the ets oncogene superfamily have now been identified. Nucleotide sequence analysis of the elk-1 cDNA clone revealed that this gene encodes a 428-residue protein whose predicted amino acid sequence showed 82% similarity to the 3' region of v-ets. The elk or related sequences appear to be transcriptionally active in testis and lung. The elk cDNA probe detects two loci in the human genome, elk-1 and elk-2, which map to chromosome regions Xp11.2 and 14q32.3, respectively. These loci are near the translocation breakpoint seen in the t(X;18) (p11.2;q11.2), which is characteristic of synovial sarcoma, and the chromosome 14q32 breakpoints seen in ataxia telangiectasia and other T cell malignancies. This suggests the possibility that rearrangements of elk loci may be involved in pathogenesis of certain tumors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rao, V N -- Huebner, K -- Isobe, M -- ar-Rushdi, A -- Croce, C M -- Reddy, E S -- CA-21124/CA/NCI NIH HHS/ -- CA-25875/CA/NCI NIH HHS/ -- CA-39860/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1989 Apr 7;244(4900):66-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wistar Institute of Anatomy and Biology, Philadelphia, PA 19104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2539641" target="_blank"〉PubMed〈/a〉

    Autoimmune target in Heymann nephritis is a glycoprotein with homology to the LDL receptor (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-06-09
    Description: The pathogenesis of Heymann nephritis, a rat model of human membranous glomerulonephritis, depends on the interaction of autoantibodies with a renal glycoprotein (GP330) on glomerular podocytes. Partial complementary DNAs coding for GP330 were isolated and sequenced. The deduced amino acid sequence from 4.3 kilobases of complementary DNA contains the sequences identical to two peptides derived from the isolated glycoprotein. The deduced amino acid sequence of this protein contains regions with homology to the human low density lipoprotein (LDL) receptor, an indication that GP330 and the LDL receptor may be members of the same gene family. Autoantibodies from the kidneys of rats with Heymann nephritis reacted with a nonglycosylated segment of GP330 that contains cysteine-rich 40-amino acid repeats, which are also features of the LDL receptor. GP330 is also similar in some regions to the mouse epidermal growth factor precursor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raychowdhury, R -- Niles, J L -- McCluskey, R T -- Smith, J A -- P01-DK38452/DK/NIDDK NIH HHS/ -- R01-DK18729/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 9;244(4909):1163-5.〈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/2786251" target="_blank"〉PubMed〈/a〉

    Description: Techniques of gene amplification, molecular cloning, and sequence analysis were used to test for the presence of sequences related to human T-lymphotropic virus type I (HTLV-I) in peripheral blood mononuclear cells of six patients with multiple sclerosis (MS) and 20 normal individuals. HTLV-I sequences were detected in all six MS patients and in one individual from the control group by DNA blot analysis and molecular cloning of amplified DNAs. The viral sequence in MS patients were associated with adherent cell populations consisting predominantly of monocytes and macrophages. Molecular cloning and nucleotide sequence analysis indicated that these amplified viral sequences were related to the HTLV-I proviral genome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reddy, E P -- Sandberg-Wollheim, M -- Mettus, R V -- Ray, P E -- DeFreitas, E -- Koprowski, H -- CA-10815/CA/NCI NIH HHS/ -- NS-11036/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jan 27;243(4890):529-33.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wistar Institute of Anatomy and Biology, Philadelphia, PA 19104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2536193" target="_blank"〉PubMed〈/a〉

    Publication Date: 1989-02-24
    Description: Positron emission tomographic measurements of regional blood flow, a marker of local neuronal activity, were used to investigate the neuroanatomical correlates of a normal emotion. Healthy volunteers were studied before, during, and after anticipation of a painful electric shock. During anticipatory anxiety, there were significant blood flow increases in bilateral temporal poles, the same regions recently implicated in a lactate-induced anxiety attack in patients with panic disorder. Thus, the temporal poles seem to be involved in normal and pathological forms of human anxiety.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reiman, E M -- Fusselman, M J -- Fox, P T -- Raichle, M E -- MH-00615/MH/NIMH NIH HHS/ -- NS-00904/NS/NINDS NIH HHS/ -- NS-06833/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Feb 24;243(4894 Pt 1):1071-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, Washington University School of Medicine, St. Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2784226" target="_blank"〉PubMed〈/a〉

    An inducible endothelial cell surface glycoprotein mediates melanoma adhesion (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-12-08
    Description: Hematogenous metastasis requires the arrest and extravasation of blood-borne tumor cells, possibly involving direct adhesive interactions with vascular endothelium. Cytokine activation of cultured human endothelium increases adhesion of melanoma and carcinoma cell lines. An inducible 110-kD endothelial cell surface glycoprotein, designated INCAM-110, appears to mediate adhesion of melanoma cells. In addition, an inducible endothelial receptor for neutrophils, ELAM-1, supports the adhesion of a human colon carcinoma cell line. Thus, activation of vascular endothelium in vivo that results in increased expression of INCAM-110 and ELAM-1 may promote tumor cell adhesion and affect the incidence and distribution of metastases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rice, G E -- Bevilacqua, M P -- HL 07727/HL/NHLBI NIH HHS/ -- P01 HL36028/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Dec 8;246(4935):1303-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Brigham and Women's Hospital, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2588007" target="_blank"〉PubMed〈/a〉

    Publication Date: 1989-10-27
    Description: Expression of the c-myc oncogene is deregulated in a variety of malignancies. Rearrangement and mutation of the c-myc locus is a characteristic feature of human Burkitt's lymphoma. Whether deregulation is solely a result of mutation of c-myc or whether it is influenced by the transformed B cell context has not been determined. A translocated and mutated allele of c-myc was stably transfected into fibroblasts. The rearranged allele was expressed indistinguishably from a normal c-myc gene: it had serum-regulated expression, was transcribed with normal promoter preference, and was strongly attenuated. Thus mutations by themselves are insufficient to deregulate c-myc transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Richman, A -- Hayday, A -- 40364/PHS HHS/ -- GM 07499/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Oct 27;246(4929):494-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biology Department, Yale University, New Haven, CT 06511.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2683072" target="_blank"〉PubMed〈/a〉

    Description: A procedure has been developed for introducing exogenous DNA into mouse eggs by injection of chromosome fragments. Chromosome fragments were dissected from human metaphase spreads and microinjected into the pronuclei of fertilized mouse eggs. Many of the injected eggs subsequently exhibited normal pre- and postimplantation development. Embryos obtained from eggs injected with centromeric fragments retained human centromeric DNA as demonstrated by in situ hybridization analysis. From eggs injected with noncentromeric fragments, a mouse was obtained whose tail tissue exhibited the presence of human DNA. This procedure should facilitate incorporation of very large (more than 10 megabases) DNA fragments into cells and embryos without the need for cloned sequences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Richa, J -- Lo, C W -- New York, N.Y. -- Science. 1989 Jul 14;245(4914):175-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biology Department, University of Pennsylvania, Philadelphia 19104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2749254" target="_blank"〉PubMed〈/a〉

    Description: Overlapping complementary DNA clones were isolated from epithelial cell libraries with a genomic DNA segment containing a portion of the putative cystic fibrosis (CF) locus, which is on chromosome 7. Transcripts, approximately 6500 nucleotides in size, were detectable in the tissues affected in patients with CF. The predicted protein consists of two similar motifs, each with (i) a domain having properties consistent with membrane association and (ii) a domain believed to be involved in ATP (adenosine triphosphate) binding. A deletion of three base pairs that results in the omission of a phenylalanine residue at the center of the first predicted nucleotide-binding domain was detected in CF patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Riordan, J R -- Rommens, J M -- Kerem, B -- Alon, N -- Rozmahel, R -- Grzelczak, Z -- Zielenski, J -- Lok, S -- Plavsic, N -- Chou, J L -- DK34944/DK/NIDDK NIH HHS/ -- DK39690/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1989 Sep 8;245(4922):1066-73.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Hospital for Sick Children, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2475911" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-08-18
    Description: Polarized epithelial cells play fundamental roles in the ontogeny and function of a variety of tissues and organs in mammals. The morphogenesis of a sheet of polarized epithelial cells (the trophectoderm) is the first overt sign of cellular differentiation in early embryonic development. In the adult, polarized epithelial cells line all body cavities and occur in tissues that carry out specialized vectorial transport functions of absorption and secretion. The generation of this phenotype is a multistage process requiring extracellular cues and the reorganization of proteins in the cytoplasm and on the plasma membrane; once established, the phenotype is maintained by the segregation and retention of specific proteins and lipids in distinct apical and basal-lateral plasma membrane domains.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rodriguez-Boulan, E -- Nelson, W J -- GM 35527/GM/NIGMS NIH HHS/ -- GM-34107/GM/NIGMS NIH HHS/ -- HL-37675/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Aug 18;245(4919):718-25.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology and Anatomy, Cornell University Medical College, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2672330" target="_blank"〉PubMed〈/a〉

    Circumsporozoite protein heterogeneity in the human malaria parasite Plasmodium vivax (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-09-01
    Description: Phenotypic heterogeneity in the repetitive portion of a human malaria circumsporozoite (CS) protein, a major target of candidate vaccines, has been found. Over 14% of clinical cases of uncomplicated Plasmodium vivax malaria at two sites in western Thailand produced sporozoites immunologically distinct from previously characterized examples of the species. Monoclonal antibodies to the CS protein of other P. vivax isolates and to other species of human and simian malarias did not bind to these nonreactive sporozoites, nor did antibodies from monkeys immunized with a candidate vaccine made from the repeat portion of a New World CS protein. The section of the CS protein gene between the conserved regions I and II of a nonreactive isolate contained a nonapeptide repeat, Ala-Asn-Gly-Ala-Gly-Asn-Gln-Pro-Gly, identical at only three amino acid positions with published nonapeptide sequences. This heterogeneity implies that a P. vivax vaccine based on the CS protein repeat of one isolate will not be universally protective.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosenberg, R -- Wirtz, R A -- Lanar, D E -- Sattabongkot, J -- Hall, T -- Waters, A P -- Prasittisuk, C -- New York, N.Y. -- Science. 1989 Sep 1;245(4921):973-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomology, Armed Forces Research Institute of Medical Sciences, Bangkok, Thailand.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2672336" target="_blank"〉PubMed〈/a〉

    Adipsin and complement factor D activity: an immune-related defect in obesity (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-06-23
    Description: Adipsin is a serine protease that is secreted by adipocytes into the bloodstream; it is deficient in several animal models of obesity, representing a striking example of defective gene expression in this disorder. Recombinant mouse adipsin was purified and its biochemical and enzymatic properties were studied in order to elucidate the function of this protein. Activated adipsin has little or no proteolytic activity toward most substrates but has the same activity as human complement factor D, cleaving complement factor B when it is complexed with activated complement component C3. Like authentic factor D, adipsin can activate the alternative pathway of complement, resulting in red blood cell lysis. Decreased (58 to 80 percent) complement factor D activity, relative to lean controls, was observed as a common feature of several experimental models of obesity, including the ob/ob, db/db, and monosodium glutamate (MSG)-injected mouse and the fa/fa rat. These results suggest that adipsin and the alternative pathway of complement may play an unexpected but important role in the regulation of systemic energy balance in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosen, B S -- Cook, K S -- Yaglom, J -- Groves, D L -- Volanakis, J E -- Damm, D -- White, T -- Spiegelman, B M -- DK31403/DK/NIDDK NIH HHS/ -- DK34605/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 23;244(4911):1483-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana-Farber Cancer Institute, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2734615" target="_blank"〉PubMed〈/a〉

    Identification of the cystic fibrosis gene: chromosome walking and jumping (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-09-08
    Description: An understanding of the basic defect in the inherited disorder cystic fibrosis requires cloning of the cystic fibrosis gene and definition of its protein product. In the absence of direct functional information, chromosomal map position is a guide for locating the gene. Chromosome walking and jumping and complementary DNA hybridization were used to isolate DNA sequences, encompassing more than 500,000 base pairs, from the cystic fibrosis region on the long arm of human chromosome 7. Several transcribed sequences and conserved segments were identified in this cloned region. One of these corresponds to the cystic fibrosis gene and spans approximately 250,000 base pairs of genomic DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rommens, J M -- Iannuzzi, M C -- Kerem, B -- Drumm, M L -- Melmer, G -- Dean, M -- Rozmahel, R -- Cole, J L -- Kennedy, D -- Hidaka, N -- DK34944/DK/NIDDK NIH HHS/ -- DK39690/DK/NIDDK NIH HHS/ -- N01-CO-74102/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1989 Sep 8;245(4922):1059-65.〈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/2772657" target="_blank"〉PubMed〈/a〉

    Tumor suppressor genes: the puzzle and the promise (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-12-15
    Description: Tumor suppressor genes are wild-type alleles of genes that play regulatory roles in cell proliferation, differentiation, and other cellular and systemic processes. It is their loss or inactivation that is oncogenic. The first evidence of tumor suppressor genes appeared in the early 1970s, but only within the past few years has a wealth of new information illuminated the central importance of these genes. Two or more different suppressor genes may be inactivated in the same tumors, and the same suppressors may be inactive in different tumor types (for example, lung, breast, and colon). The suppressor genes already identified are involved in cell cycle control, signal transduction, angiogenesis, and development, indicating that they contribute to a broad array of normal and tumor-related functions. It is proposed that tumor suppressor genes provide a vast untapped resource for anticancer therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sager, R -- New York, N.Y. -- Science. 1989 Dec 15;246(4936):1406-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Cancer Genetics, Dana-Farber Cancer Institute, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2574499" target="_blank"〉PubMed〈/a〉

    Developmental biology of T cell receptors (1989)

    Details
    Publication Date: 1989-05-26
    Description: T cell receptors are the antigen-recognizing elements found on the effector cells of the immune system. Two isotypes have been discovered, TCR-gamma delta and TCR-alpha beta, which appear in that order during ontogeny. The maturation of prothymocytes that colonize the thymic rudiment at defined gestational stages occurs principally within the thymus, although some evidence for extrathymic maturation also exists. The maturation process includes the rearrangement and expression of the T cell receptor genes. Determination of these mechanisms, the lineages of the cells, and the subsequent thymic selection that results in self-tolerance is the central problem in developmental immunology and is important for the understanding of autoimmune diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Strominger, J L -- New York, N.Y. -- Science. 1989 May 26;244(4907):943-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, Harvard University, Cambridge, MA 02138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2658058" target="_blank"〉PubMed〈/a〉

    Publication Date: 1989-06-16
    Description: Current therapies for most human genetic diseases are inadequate. In response to the need for effective treatments, modern molecular genetics is providing tools for an unprecedented new approach to disease treatment through an attack directly on mutant genes. Recent results with several target organs and gene transfer techniques have led to broad medical and scientific acceptance of the feasibility of this "gene therapy" concept for disorders of the bone marrow, liver, and central nervous system; some kinds of cancer; and deficiencies of circulating enzymes, hormones, and coagulation factors. The most well-developed models involve alteration of mutant target genes by gene transfer with recombinant pathogenic viruses in order to express new genetic information and to correct disease phenotypes--the conversion of the swords of pathology into the plowshares of therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Friedmann, T -- New York, N.Y. -- Science. 1989 Jun 16;244(4910):1275-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, School of Medicine, University of California, San Diego, La Jolla 92093.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2660259" target="_blank"〉PubMed〈/a〉

    DNA topoisomerase I--targeted chemotherapy of human colon cancer in xenografts (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-11-24
    Description: Drug development is needed to improve chemotherapy of patients with locally advanced or metastatic colon carcinoma, who otherwise have an unfavorable prognosis. DNA topoisomerase I, a nuclear enzyme important for solving topological problems arising during DNA replication and for other cellular functions, has been identified as a principal target of a plant alkaloid 20(S)-camptothecin. Significantly increased concentrations of this enzyme, compared to that in normal colonic mucosa, were found in advanced stages of human colon adenocarcinoma and in xenografts of colon cancer carried by immunodeficient mice. Several synthetic analogs of camptothecin, selected by tests with the purified enzyme and tissue-culture screens, were evaluated in the xenograft model. Unlike other anticancer drugs tested, 20(RS)-9-amino-camptothecin (9-AC) induced disease-free remissions. The overall drug toxicity was low and allowed for repeated courses of treatment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Giovanella, B C -- Stehlin, J S -- Wall, M E -- Wani, M C -- Nicholas, A W -- Liu, L F -- Silber, R -- Potmesil, M -- CA-11655/CA/NCI NIH HHS/ -- CA-16087/CA/NCI NIH HHS/ -- CA-349636/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Nov 24;246(4933):1046-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Stehlin Foundation for Cancer Research, St. Joseph Hospital, Houston, TX 77002.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2555920" target="_blank"〉PubMed〈/a〉

    The RNA processing enzyme RNase MRP is identical to the Th RNP and related to RNase P (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-09-22
    Description: Sera from patients with autoimmune diseases often contain antibodies that bind ribonucleoproteins (RNPs). Sera from 30 such patients were found to immunoprecipitate ribonuclease P (RNase P), an RNP enzyme required to process the 5' termini of transfer RNA transcripts in nuclei and mitochondria of eukaryotic cells. All 30 sera also immunoprecipitated the nucleolar Th RNP, indicating that the two RNPs are structurally related. Nucleotide sequence analysis of the Th RNP revealed it was identical to the RNA component of the mitochondrial RNA processing enzyme known as RNase MRP. Antibodies that immunoprecipitated the Th RNP selectively depleted murine and human cell extracts of RNase MRP activity, indicating that the Th and RNase MRP RNPs are identical. Since RNase P and RNase MRP are not associated with each other during biochemical purification, we suggest that these two RNA processing enzymes share a common autoantigenic polypeptide.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gold, H A -- Topper, J N -- Clayton, D A -- Craft, J -- AI 26853/AI/NIAID NIH HHS/ -- GM 33088-19/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Sep 22;245(4924):1377-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Yale University School of Medicine, New Haven, CT 06511.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2476849" target="_blank"〉PubMed〈/a〉

    Interleukin-2 receptor beta chain gene: generation of three receptor forms by cloned human alpha and beta chain cDNA's (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-05-05
    Description: Interleukin-2 (IL-2) binds to two distinct receptor molecules, the IL-2 receptor alpha (IL-2R alpha, p55) chain and the newly identified IL-2 receptor beta (IL-2R beta, p70-75) chain. The cDNA encoding the human IL-2R beta chain has now been isolated. The overall primary structure of the IL-2R beta chain shows no apparent homology to other known receptors. Unlike the IL-2R alpha chain, the IL-2R beta chain has a large cytoplasmic region in which a functional domain (or domains) mediating an intracellular signal transduction pathway (or pathways) may be embodied. The cDNA-encoded beta chain binds and internalizes IL-2 when expressed on T lymphoid cells but not fibroblast cells. Furthermore, the cDNA gives rise to the generation of high-affinity IL-2 receptor when co-expressed with the IL-2R alpha chain cDNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hatakeyama, M -- Tsudo, M -- Minamoto, S -- Kono, T -- Doi, T -- Miyata, T -- Miyasaka, M -- Taniguchi, T -- New York, N.Y. -- Science. 1989 May 5;244(4904):551-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Molecular and Cellular Biology, Osaka University, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2785715" target="_blank"〉PubMed〈/a〉

    The Fc and not CD4 receptor mediates antibody enhancement of HIV infection in human cells (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-06-16
    Description: Antibodies that enhance human immunodeficiency virus (HIV) infectivity have been found in the blood of infected individuals and in infected or immunized animals. These findings raise serious concern for the development of a safe vaccine against acquired immunodeficiency syndrome. To address the in vivo relevance and mechanism of this phenomenon, antibody-dependent enhancement of HIV infectivity in peripheral blood macrophages, lymphocytes, and human fibroblastoid cells was studied. Neither Leu3a, a monoclonal antibody directed against the CD4 receptor, nor soluble recombinant CD4 even at high concentrations prevented this enhancement. The addition of monoclonal antibody to the Fc receptor III (anti-FcRIII), but not of antibodies that react with FcRI or FcRII, inhibited HIV type 1 and HIV type 2 enhancement in peripheral blood macrophages. Although enhancement of HIV infection in CD4+ lymphocytes could not be blocked by anti-FcRIII, it was inhibited by the addition of human immunoglobulin G aggregates. The results indicate that the FcRIII receptor on human macrophages and possibly another Fc receptor on human CD4+ lymphocytes mediate antibody-dependent enhancement of HIV infectivity and that this phenomenon proceeds through a mechanism independent of the CD4 protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Homsy, J -- Meyer, M -- Tateno, M -- Clarkson, S -- Levy, J A -- AI-26471/AI/NIAID NIH HHS/ -- R01-AI-24499/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 16;244(4910):1357-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, 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/2786647" target="_blank"〉PubMed〈/a〉

    Publication Date: 1989-09-01
    Description: It is argued that the need to improve science education should be a national priority. Ways are suggested by which the federal government and the scientific community, working together, can address this issue. It is recommended that scientists, engineers, and educators make a significant personal and institutional commitment to participate in science education activities, and that the President of the United States provide the personal leadership to generate a national commitment to the improvement of education at all levels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Massey, W E -- New York, N.Y. -- Science. 1989 Sep 1;245(4921):915-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Argonne National Laboratory, University of Chicago, IL.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2772643" target="_blank"〉PubMed〈/a〉

    Isolation of a novel receptor cDNA establishes the existence of two PDGF receptor genes (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-02-10
    Description: A genomic sequence and cloned complementary DNA has been identified for a novel receptor-like gene of the PDGF receptor/CSF1 receptor subfamily (platelet-derived growth factor receptor/colony-stimulating factor type 1 receptor). The gene recognized a 6.4-kilobase transcript that was coexpressed in normal human tissues with the 5.3-kilobase PDGF receptor messenger RNA. Introduction of complementary DNA of the novel gene into COS-1 cells led to expression of proteins that were specifically detected with antiserum directed against a predicted peptide. When the new gene was transfected into COS-1 cells, a characteristic pattern of binding of the PDGF isoforms was observed, which was different from the pattern observed with the known PDGF receptor. Tyrosine phosphorylation of the receptor in response to the PDGF isoforms was also different from the known receptor. The new PDGF receptor gene was localized to chromosome 4q11-4q12. The existence of genes encoding two PDGF receptors that interact in a distinct manner with three different PDGF isoforms likely confers considerable regulatory flexibility in the functional responses to PDGF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsui, T -- Heidaran, M -- Miki, T -- Popescu, N -- La Rochelle, W -- Kraus, M -- Pierce, J -- Aaronson, S -- New York, N.Y. -- Science. 1989 Feb 10;243(4892):800-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cellular and Molecular Biology, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2536956" target="_blank"〉PubMed〈/a〉

    The gene for enhancer binding proteins E12/E47 lies at the t(1;19) breakpoint in acute leukemias (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-10-20
    Description: The gene (E2A) that codes for proteins with the properties of immunoglobulin enhancer binding factors E12/E47 was mapped to chromosome region 19p13.2-p13.3, a site associated with nonrandom translocations in acute lymphoblastic leukemias. The majority of t(1;19)(q23;p13)-carrying leukemias and cell lines studied contained rearrangements of E2A as determined by DNA blot analyses. The rearrangements altered the E2A transcriptional unit, resulting in the synthesis of a transcript larger than the normal-sized E2A mRNAs in one of the cell lines with this translocation. These observations indicate that the gene for a transcription factor is located at the breakpoint of a consistently recurring chromosomal translocation in many acute leukemias and suggest a direct role for alteration of such factors in the pathogenesis of some malignancies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mellentin, J D -- Murre, C -- Donlon, T A -- McCaw, P S -- Smith, S D -- Carroll, A J -- McDonald, M E -- Baltimore, D -- Cleary, M L -- CA30969/CA/NCI NIH HHS/ -- CA42106/CA/NCI NIH HHS/ -- CA42971/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Oct 20;246(4928):379-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Stanford University School of Medicine, CA 94025.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2799390" target="_blank"〉PubMed〈/a〉

    Coordinate regulation and sensory transduction in the control of bacterial virulence (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-02-17
    Description: Genes and operons that encode bacterial virulence factors are often subject to coordinate regulation. These regulatory systems are capable of responding to various environmental signals that may be encountered during the infectious cycle. For some pathogens, proteins that mediate sensory transduction and virulence control are similar to components of other bacterial information processing systems. Understanding the molecular mechanisms governing global regulation of pathogenicity is essential for understanding bacterial infectious diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, J F -- Mekalanos, J J -- Falkow, S -- AI23945/AI/NIAID NIH HHS/ -- AI26195/AI/NIAID NIH HHS/ -- AI26289/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1989 Feb 17;243(4893):916-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2537530" target="_blank"〉PubMed〈/a〉

    Cell cycle-dependent regulation of phosphorylation of the human retinoblastoma gene product (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-12-08
    Description: The human retinoblastoma gene (RB1) encodes a protein (Rb) of 105 kilodaltons that can be phosphorylated. Analysis of Rb metabolism has shown that the protein has a half-life of more than 10 hours and is synthesized at all phases of the cell cycle. Newly synthesized Rb is not extensively phosphorylated (it is "underphosphorylated") in cells in the G0 and G1 phases but is phosphorylated at multiple sites at the G1/S boundary and in S phase. HL-60 cells that were induced to terminally differentiate by various chemicals lost their ability to phosphorylate newly synthesized Rb at multiple sites when cell growth was arrested. These findings suggest that underphosphorylated Rb may restrict cell proliferation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mihara, K -- Cao, X R -- Yen, A -- Chandler, S -- Driscoll, B -- Murphree, A L -- T'Ang, A -- Fung, Y K -- 5P30CA14089/CA/NCI NIH HHS/ -- CA 44754/CA/NCI NIH HHS/ -- EY 07846/EY/NEI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Dec 8;246(4935):1300-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology/Oncology and Ophthalmology, Childrens Hospital of Los Angeles, CA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2588006" target="_blank"〉PubMed〈/a〉

    Delay of gratification in children (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-05-26
    Description: To function effectively, individuals must voluntarily postpone immediate gratification and persist in goal-directed behavior for the sake of later outcomes. The present research program analyzed the nature of this type of future-oriented self-control and the psychological processes that underlie it. Enduring individual differences in self-control were found as early as the preschool years. Those 4-year-old children who delayed gratification longer in certain laboratory situations developed into more cognitively and socially competent adolescents, achieving higher scholastic performance and coping better with frustration and stress. Experiments in the same research program also identified specific cognitive and attentional processes that allow effective self-regulation early in the course of development. The experimental results, in turn, specified the particular types of preschool delay situations diagnostic for predicting aspects of cognitive and social competence later in life.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mischel, W -- Shoda, Y -- Rodriguez, M I -- New York, N.Y. -- Science. 1989 May 26;244(4907):933-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Columbia University, New York 10027〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2658056" target="_blank"〉PubMed〈/a〉

    Synergism between HIV gp120 and gp120-specific antibody in blocking human T cell activation (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-09-22
    Description: The human immunodeficiency virus (HIV) binds to CD4-positive cells through interaction of its envelope glycoprotein (gp120) with the CD4 molecule. CD4 is a prominent immunoregulatory molecule, and chronic exposure to antibody against CD4 (anti-CD4) has been shown to cause immunodeficiency in mice. T cell-dependent in vitro immune responses can also be inhibited by anti-CD4. Experimental findings reported here indicate that CD4-bound gp120 attracts gp120-specific antibodies derived from the blood of HIV-seropositive individuals to form a trimolecular complex with itself and CD4. Thus targeted to CD4, the gp120-specific antibody functions as an antibody to CD4; it cross-links and modulates the CD4 molecules and suppresses the activation of T cells as measured by mobilization of intracellular calcium (Ca2i+). The synergism between gp120 and anti-gp120 in blocking T cell activation occurs at low concentrations of both components. Neither gp120 nor anti-gp120 inhibits T cell activation by itself in the concentrations tested.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mittler, R S -- Hoffmann, M K -- New York, N.Y. -- Science. 1989 Sep 22;245(4924):1380-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Bristol-Myers Company, Wallingford, CT 06492.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2571187" target="_blank"〉PubMed〈/a〉

    Description: The receptor with high affinity for immunoglobulin E (IgE) on mast cells and basophils is critical in initiating allergic reactions. It is composed of an IgE-binding alpha subunit, a beta subunit, and two gamma subunits. The human alpha subunit was expressed on transfected cells in the presence of rat beta and gamma subunits or in the presence of the gamma subunit alone. The IgE binding properties of the expressed human alpha were characteristic of receptors on normal human cells. These results now permit a systematic analysis of human IgE binding and a search for therapeutically useful inhibitors of that binding.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, L -- Blank, U -- Metzger, H -- Kinet, J P -- New York, N.Y. -- Science. 1989 Apr 21;244(4902):334-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section on Chemical Immunology, National Institute of Arthritis and Musculoskeletal and Skin Diseases, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2523561" target="_blank"〉PubMed〈/a〉

    Description: The active hormonal form of vitamin D3, 1,25-dihydroxyvitamin D3[1,25(OH), which regulates cellular replication and function in many tissues and has a role in bone and calcium homeostasis, acts through a hormone receptor homologous with other steroid and thyroid hormone receptors. A 1,25(OH)2D3-responsive element (VDRE), which is within the promoter for osteocalcin [a bone protein induced by 1,25(OH)2D3] is unresponsive to other steroid hormones, can function in a heterologous promoter, and contains a doubly palindromic DNA sequence (TTGGTGACTCACCGGGTGAAC; -513 to -493 bp), with nucleotide sequence homology to other hormone responsive elements. The potent glucocorticoid repression of 1,25(OH)2D3 induction and of basal activity of this promoter acts through a region between -196 and +34 bp, distinct from the VDRE.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morrison, N A -- Shine, J -- Fragonas, J C -- Verkest, V -- McMenemy, M L -- Eisman, J A -- New York, N.Y. -- Science. 1989 Dec 1;246(4934):1158-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Garvan Institute of Medical Research, St. Vincents Hospital, Sydney, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2588000" target="_blank"〉PubMed〈/a〉
