    Purification, cloning, and expression of ciliary neurotrophic factor (CNTF) (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-11-24
    Description: Ciliary neurotrophic factor (CNTF) is one of a small number of proteins with neurotrophic activities distinct from nerve growth factor (NGF). CNTF has now been purified and cloned and the primary structure of CNTF from rabbit sciatic nerve has been determined. Biologically active CNTF has been transiently expressed from a rabbit complementary DNA clone. CNTF is a neural effector without significant sequence homologies to any previously reported protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, L F -- Mismer, D -- Lile, J D -- Armes, L G -- Butler, E T 3rd -- Vannice, J L -- Collins, F -- New York, N.Y. -- Science. 1989 Nov 24;246(4933):1023-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Protein Chemistry Group, Synergen, Inc., Boulder, CO 80301.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2587985" target="_blank"〉PubMed〈/a〉

    Expression of functional nerve growth factor receptors after gene transfer (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-01-20
    Description: Nerve growth factor (NGF) interacts with both high affinity (Kd = 10(-10)-10(-11)M) and low affinity (Kd = 10(-8)-10(-9)M) receptors; the binding of NGF to the high affinity receptor is correlated with biological actions of NGF. To determine whether a single NGF binding protein is common to both forms of the receptor, a full-length receptor cDNA was introduced in the NR18 cell line, an NGF receptor-deficient variant of the PC12 pheochromocytoma cell line. The transformant displayed (i) both high and low affinity receptors detectable by receptor binding; (ii) an affinity cross-linking pattern with 125I-labeled NGF similar to that of the parent PC12 cell line; and (iii) biological responsiveness to NGF as assayed by induction of c-fos transcription. These findings support the hypothesis that a single binding protein is common to both forms of the NGF receptor and suggest that an additional protein is required to produce the high affinity form of the NGF receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hempstead, B L -- Schleifer, L S -- Chao, M V -- HD23315/HD/NICHD NIH HHS/ -- NS-21072/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jan 20;243(4889):373-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology/Oncology, 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/2536190" target="_blank"〉PubMed〈/a〉

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

    Identification of the fusion peptide of primate immunodeficiency viruses (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-05-12
    Description: Membrane fusion induced by the envelope glycoproteins of human and simian immunodeficiency viruses (HIV and SIVmac) is a necessary step for the infection of CD4 cells and for the formation of syncytia after infection. Identification of the region in these molecules that mediates the fusion events is important for understanding and possibly interfering with HIV/SIVmac infection and pathogenesis. Amino acid substitutions were made in the 15 NH2-terminal residues of the SIVmac gp32 transmembrane glycoprotein, and the mutants were expressed in recombinant vaccinia viruses, which were then used to infect CD4-expressing T cell lines. Mutations that increased the overall hydrophobicity of the gp32 NH2-terminus increased the ability of the viral envelope to induce syncytia formation, whereas introduction of polar or charged amino acids in the same region abolished the fusogenic function of the viral envelope. Hydrophobicity in the NH2-terminal region of gp32 may therefore be an important correlate of viral virulence in vivo and could perhaps be exploited to generate a more effective animal model for the study of acquired immunodeficiency syndrome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bosch, M L -- Earl, P L -- Fargnoli, K -- Picciafuoco, S -- Giombini, F -- Wong-Staal, F -- Franchini, G -- New York, N.Y. -- Science. 1989 May 12;244(4905):694-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Tumor Cell Biology, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2541505" target="_blank"〉PubMed〈/a〉

    AP1/jun function is differentially induced in promotion-sensitive and resistant JB6 cells (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-05-05
    Description: Tumor promoters may bring about events that lead to neoplastic transformation by inducing specific promotion-relevant effector genes. Functional activation of the transacting transcription factor AP-1 by the phorbol ester 12-O-tetradecanoylphorbol-13-acetate (TPA) may play an essential role in this process. Clonal genetic variants of mouse epidermal JB6 cells that are genetically susceptible (P+) or resistant (P-) to promotion of transformation by TPA were transfected with 3XTRE-CAT, a construct that has AP-1 cis-enhancer sequences attached to a reporter gene encoding chloramphenicol acetyltransferase (CAT). Transfected JB6 P+, but not P- variants, showed TPA-inducible CAT synthesis. Epidermal growth factor, another transformation promoter in JB6 cells, also caused P+ specific induction of CAT gene expression. These results demonstrate an association between induced AP-1 function and sensitivity to promotion of neoplastic transformation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bernstein, L R -- Colburn, N H -- New York, N.Y. -- Science. 1989 May 5;244(4904):566-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Johns Hopkins University, Department of Biology, Baltimore, MD 21218.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2541502" target="_blank"〉PubMed〈/a〉

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

    Mapping the Drosophila genome with yeast artificial chromosomes (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-11-03
    Description: The ability to clone large fragments of DNA in yeast artificial chromosomes (YAC's) has created the possibility of obtaining global physical maps of complex genomes. For this application to be feasible, most sequences in complex genomes must be able to be cloned in YAC's, and most clones must be genetically stable and colinear with the genomic sequences from which they originated (that is, not liable to undergo rearrangement). These requirements have been met with a YAC library containing DNA fragments from Drosophila melanogaster ranging in size up to several hundred kilobase pairs. Preliminary characterization of the Drosophila YAC library was carried out by in situ hybridization of random clones and analysis of clones containing known sequences. The results suggest that most euchromatic sequences can be cloned. The library also contains clones in which the inserted DNA is derived from the centromeric heterochromatin. The locations of 58 clones collectively representing about 8 percent of the euchromatic genome are presented.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garza, D -- Ajioka, J W -- Burke, D T -- Hartl, D L -- New York, N.Y. -- Science. 1989 Nov 3;246(4930):641-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Washington University School of Medicine, St. Louis, MO 63110-1095.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2510296" target="_blank"〉PubMed〈/a〉

    Description: A substitution mutation has been introduced into the c-abl locus of murine embryonic stem cells by homologous recombination between exogenously added DNA and the endogenous gene, and these cells have been used to generate chimeric mice. It is shown that the c-abl mutation was transmitted to progeny by several male chimeras. This work demonstrates the feasibility of germ-line transmission of a mutation introduced into a nonselectable autosomal gene by homologous recombination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schwartzberg, P L -- Goff, S P -- Robertson, E J -- P01 CA 23767/CA/NCI NIH HHS/ -- R01 HD 25208/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1989 Nov 10;246(4931):799-803.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biophysics, Columbia University, College of Physicians & Surgeons, New York, NY 10032.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2554496" target="_blank"〉PubMed〈/a〉

    Metastatic hibernomas in transgenic mice expressing an alpha-amylase-SV40 T antigen hybrid gene (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-04-28
    Description: Mice transgenic for a hybrid gene containing the liver promoter of the mouse amylase gene (Amy-1a) fused to the SV40 tumor antigen coding region unexpected developed malignant brown adipose tissue tumors (malignant hibernomas). Expression of the alpha-amylase gene had previously been thought to be confined to the liver parotid, and pancreas; however, analysis of white and brown adipose tissue from nontransgenic mice revealed expression of the endogenous Amy-1a gene in these tissues. Gene constructs driven by the Amy-1a liver promoter thus provide a means of targeting gene expression to the adipocyte cell lineage in transgenic mice. Moreover the high frequency of metastases in the liver, lungs, spleen, heart, and adrenals of these mice provides an experimental system in which to study the development of disseminated malignancy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fox, N -- Crooke, R -- Hwang, L H -- Schibler, U -- Knowles, B B -- Solter, D -- CA-10815/CA/NCI NIH HHS/ -- CA-18470/CA/NCI NIH HHS/ -- CA-21124/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Apr 28;244(4903):460-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wistar Institute, Philadelphia, PA 19104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2785714" target="_blank"〉PubMed〈/a〉
