    Neurotoxicity of a fragment of the amyloid precursor associated with Alzheimer's disease (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-07-28
    Description: Amyloid deposition in senile plaques and the cerebral vasculature is a marker of Alzheimer's disease. Whether amyloid itself contributes to the neurodegenerative process or is simply a by-product of that process is unknown. Pheochromocytoma (PC12) and fibroblast (NIH 3T3) cell lines were transfected with portions of the gene for the human amyloid precursor protein. Stable PC12 cell transfectants expressing a specific amyloid-containing fragment of the precursor protein gradually degenerated when induced to differentiate into neuronal cells with nerve growth factor. Conditioned medium from these cells was toxic to neurons in primary hippocampal cultures, and the toxic agent could be removed by immunoabsorption with an antibody directed against the amyloid polypeptide. Thus, a peptide derived from the amyloid precursor may be neurotoxic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yankner, B A -- Dawes, L R -- Fisher, S -- Villa-Komaroff, L -- Oster-Granite, M L -- Neve, R L -- HD 18655/HD/NICHD NIH HHS/ -- HD 18658/HD/NICHD NIH HHS/ -- NS 01240/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Jul 28;245(4916):417-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Harvard Medical School, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2474201" target="_blank"〉PubMed〈/a〉

    Cloning of genomic and complementary DNA from Shaker, a putative potassium channel gene from Drosophila (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-08-14
    Description: On the basis of electrophysiological analysis of Shaker mutants, the Shaker locus of Drosophila melanogaster has been proposed to encode a structural component of a voltage-dependent potassium channel, the A channel. Unlike sodium channels, acetylcholine receptors, and calcium channels, K+ channels have not been purified biochemically. To facilitate biochemical studies of a K+ channel, genomic DNA from the Shaker locus has been cloned. Rearrangements in five Shaker mutants have been mapped to a 60-kilobase segment of the genome. Four complementary DNA clones have been analyzed. These clones indicate that the Shaker gene contains multiple exons distributed over at least 65 kilobases of genomic DNA in the region where the mutations mapped. Furthermore, the gene may produce several classes of alternatively spliced transcripts. Two of the complementary DNA clones have been sequenced and their sequences support the hypothesis that Shaker encodes a component of a K+ channel.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Papazian, D M -- Schwarz, T L -- Tempel, B L -- Jan, Y N -- Jan, L Y -- NS15963/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1987 Aug 14;237(4816):749-53.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2441470" target="_blank"〉PubMed〈/a〉

    Multiple, distinct forms of bovine and human protein kinase C suggest diversity in cellular signaling pathways (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-22
    Description: A new family of protein kinase C-related genes has been identified in bovine, human, and rat genomes. The alpha-, beta-, and gamma-type protein kinase sequences are highly homologous, include a kinase domain, and potential calcium-binding sites, and they contain interspersed variable regions. The corresponding genes are located on distinct human chromosomes; the possibility of even greater genetic complexity of this gene family is suggested by Northern and Southern hybridization analyses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coussens, L -- Parker, P J -- Rhee, L -- Yang-Feng, T L -- Chen, E -- Waterfield, M D -- Francke, U -- Ullrich, A -- New York, N.Y. -- Science. 1986 Aug 22;233(4766):859-66.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3755548" 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〉

    Commitment of mouse fibroblasts to adipocyte differentiation by DNA transfection (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-05-05
    Description: Cells of the mouse cell line 3T3-F442A can be induced by various hormones to differentiate into adipocytes, whereas cells of 3T3-C2, a subclone of 3T3, cannot. However, transfection of DNA from uninduced 3T3-F422A cells into 3T3-C2 cells permits recovery of 3T3-C2 transfectants that differentiate into adipocytes in the presence of insulin. DNA isolated from human fat tissue, when transfected into 3T3-C2 mouse cells, also gives rise to mouse transfectants that are induced to differentiate into adipocytes by the addition of insulin. Apparently, transfection of a trans-regulatory gene (or genes) from 3T3-F442A or human fat cells into 3T3-C2 cells is sufficient to commit 3T3-C2 cells to adipocyte differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, S -- Teicher, L C -- Kazim, D -- Pollack, R E -- Wise, L S -- New York, N.Y. -- Science. 1989 May 5;244(4904):582-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Columbia University, New York, NY 10027.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2470149" target="_blank"〉PubMed〈/a〉

    Cloning and expression of a Xenopus embryonic gap junction protein (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-03-03
    Description: Gap junctions in the early amphibian embryo may play a fundamental role in the regulation of differentiation by mediating the cell-to-cell transfer of chemical signals. A complementary DNA encoding a gap junction present in Xenopus oocytes and early embryos has now been cloned and sequenced. This protein sequence is homologous to the well-characterized gap junction structural proteins rat connexin32 and connexin43. RNA blot analysis of total Xenopus oocyte RNA showed hybridization to a single 1.6-kilobase band. This messenger RNA is abundant in oocytes, decreases to levels below the sensitivity of our assay by stage 15 (18 hours), and is not detectable in RNA from a number of adult organs. To confirm that the oocyte cDNA encodes a gap junction channel, the protein was over expressed in Xenopus oocytes by injection of RNA synthesized in vitro. Pairs of RNA-injected oocytes formed many more time- and voltage-sensitive cell-cell channels than water-injected pairs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ebihara, L -- Beyer, E C -- Swenson, K I -- Paul, D L -- Goodenough, D A -- GM18974/GM/NIGMS NIH HHS/ -- GM37751/GM/NIGMS NIH HHS/ -- HL28958-06/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Mar 3;243(4895):1194-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Columbia University, New York, NY 10032.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2466337" target="_blank"〉PubMed〈/a〉

    Isolation of a cDNA clone derived from a blood-borne non-A, non-B viral hepatitis genome (1989)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 1989-04-21
    Description: A random-primed complementary DNA library was constructed from plasma containing the uncharacterized non-A, non-B hepatitis (NANBH) agent and screened with serum from a patient diagnosed with NANBH. A complementary DNA clone was isolated that was shown to encode an antigen associated specifically with NANBH infections. This clone is not derived from host DNA but from an RNA molecule present in NANBH infections that consists of at least 10,000 nucleotides and that is positive-stranded with respect to the encoded NANBH antigen. These data indicate that this clone is derived from the genome of the NANBH agent and are consistent with the agent being similar to the togaviridae or flaviviridae. This molecular approach should be of great value in the isolation and characterization of other unidentified infectious agents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Choo, Q L -- Kuo, G -- Weiner, A J -- Overby, L R -- Bradley, D W -- Houghton, M -- New York, N.Y. -- Science. 1989 Apr 21;244(4902):359-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Chiron Corporation, Emeryville, CA 94608.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2523562" target="_blank"〉PubMed〈/a〉

    Deregulation of c-myc by translocation of the alpha-locus of the T-cell receptor in T-cell leukemias (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-05-16
    Description: Two human T-cell leukemias carrying a t(8;14)(q24;q11) chromosome translocation were studied for rearrangements and expression of the c-myc oncogene. For one leukemia, rearrangement was detected in a region immediately distal (3') to the c-myc locus; no rearrangements of c-myc were observed in the second case (DeF). However, studies with hybrids between human and mouse leukemic T cells indicated that in the leukemic cells of DeF, the breakpoint in chromosome 14 occurred between genes for the variable (V alpha) and the constant (C alpha) regions for the alpha chain of the T-cell receptor. The C alpha locus had translocated to a region more than 38 kilobases 3' to the involved c-myc oncogene. Since human c-myc transcripts were expressed only in hybrids carrying the 8q+ chromosome but not in hybrids containing the normal chromosome 8, it is concluded that the translocation of the C alpha locus 3' to the c-myc oncogene can result in its transcriptional deregulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Erikson, J -- Finger, L -- Sun, L -- ar-Rushdi, A -- Nishikura, K -- Minowada, J -- Finan, J -- Emanuel, B S -- Nowell, P C -- Croce, C M -- CA10815/CA/NCI NIH HHS/ -- CA25875/CA/NCI NIH HHS/ -- CA39860/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 May 16;232(4752):884-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3486470" target="_blank"〉PubMed〈/a〉

    Construction of a general human chromosome jumping library, with application to cystic fibrosis (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-02-27
    Description: In many genetic disorders, the responsible gene and its protein product are unknown. The technique known as "reverse genetics," in which chromosomal map positions and genetically linked DNA markers are used to identify and clone such genes, is complicated by the fact that the molecular distances from the closest DNA markers to the gene itself are often too large to traverse by standard cloning techniques. To address this situation, a general human chromosome jumping library was constructed that allows the cloning of DNA sequences approximately 100 kilobases away from any starting point in genomic DNA. As an illustration of its usefulness, this library was searched for a jumping clone, starting at the met oncogene, which is a marker tightly linked to the cystic fibrosis gene that is located on human chromosome 7. Mapping of the new genomic fragment by pulsed field gel electrophoresis confirmed that it resides on chromosome 7 within 240 kilobases downstream of the met gene. The use of chromosome jumping should now be applicable to any genetic locus for which a closely linked DNA marker is available.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Collins, F S -- Drumm, M L -- Cole, J L -- Lockwood, W K -- Vande Woude, G F -- Iannuzzi, M C -- GM34960/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1987 Feb 27;235(4792):1046-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2950591" target="_blank"〉PubMed〈/a〉

    Visual pigment homologies revealed by DNA hybridization (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-06-06
    Description: A bovine rhodopsin complementary DNA probe was used to detect homologous visual pigment genes in a variety of species. Under stringent DNA hybridization conditions, genomic DNA from most vertebrate species carried a single homologous fragment. Additional homologies were detected in some vertebrates by reducing the hybridization stringency. Homologous fragments were also detected in DNA isolated from invertebrate species, a unicellular alga, and an archaebacterium; many of these fragments were homologous to a Drosophila opsin probe. These results suggest that photosensory pigments in a wide variety of species arose from a common precursor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martin, R L -- Wood, C -- Baehr, W -- Applebury, M L -- EY04801/EY/NEI NIH HHS/ -- EY07008/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1986 Jun 6;232(4755):1266-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3010467" target="_blank"〉PubMed〈/a〉
