    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〉

    Smooth muscle-mediated connective tissue remodeling in pulmonary hypertension (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-07-24
    Description: Abnormal accumulation of connective tissue in blood vessels contributes to alterations in vascular physiology associated with disease states such as hypertension and atherosclerosis. Elastin synthesis was studied in blood vessels from newborn calves with severe pulmonary hypertension induced by alveolar hypoxia in order to investigate the cellular stimuli that elicit changes in pulmonary arterial connective tissue production. A two- to fourfold increase in elastin production was observed in pulmonary artery tissue and medial smooth muscle cells from hypertensive calves. This stimulation of elastin production was accompanied by a corresponding increase in elastin messenger RNA consistent with regulation at the transcriptional level. Conditioned serum harvested from cultures of pulmonary artery smooth muscle cells isolated from hypertensive animals contained one or more low molecular weight elastogenic factors that stimulated the production of elastin in both fibroblasts and smooth muscle cells and altered the chemotactic responsiveness of fibroblasts to elastin peptides. These results suggest that connective tissue changes in the pulmonary vasculature in response to pulmonary hypertension are orchestrated by the medial smooth muscle cell through the generation of specific differentiation factors that alter both the secretory phenotype and responsive properties of surrounding cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mecham, R P -- Whitehouse, L A -- Wrenn, D S -- Parks, W C -- Griffin, G L -- Senior, R M -- Crouch, E C -- Stenmark, K R -- Voelkel, N F -- CA31777/CA/NCI NIH HHS/ -- HD20521/HD/NICHD NIH HHS/ -- HL14985/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1987 Jul 24;237(4813):423-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3603030" target="_blank"〉PubMed〈/a〉

    HTLV x gene mutants exhibit novel transcriptional regulatory phenotypes (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-02-06
    Description: The human T-cell leukemia viruses, HTLV-I and HTLV-II, contain a gene, termed x, with transcriptional regulatory function. The properties of the x proteins were analyzed by constructing mutant genes containing site-directed deletions and point mutations. The results demonstrate that the amino terminal 17 amino acids of the x protein constitute part of a functional domain that is critical for the transcriptional activating properties of the protein. Within this region, substitution of a leucine residue for a proline residue results in major changes in the trans-activation phenotype of the protein. The mutant HTLV-II x protein, though incapable of activating the HTLV-II long terminal repeat, will block trans-activation of the HTLV-II long terminal repeat by the wild-type protein. The altered phenotype of this mutant suggests a potential negative regulatory function of the x protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wachsman, W -- Cann, A J -- Williams, J L -- Slamon, D J -- Souza, L -- Shah, N P -- Chen, I S -- CA 30388/CA/NCI NIH HHS/ -- CA 32727/CA/NCI NIH HHS/ -- CA 38597/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1987 Feb 6;235(4789):674-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3027894" target="_blank"〉PubMed〈/a〉

    Cloning of human mineralocorticoid receptor complementary DNA: structural and functional kinship with the glucocorticoid receptor (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-07-17
    Description: Low-stringency hybridization with human glucocorticoid receptor (hGR) complementary DNA was used to isolate a new gene encoding a predicted 107-kilodalton polypeptide. Expression studies demonstrate its ability to bind aldosterone with high affinity and to activate gene transcription in response to aldosterone, thus establishing its identity as the human mineralocorticoid receptor (hMR). This molecule also shows high affinity for glucocorticoids and stimulates a glucocorticoid-responsive promoter. Together the hMR and hGR provide unexpected functional diversity in which hormone-binding properties, target gene interactions, and patterns of tissue-specific expression may be used in a combinatorial fashion to achieve complex physiologic control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arriza, J L -- Weinberger, C -- Cerelli, G -- Glaser, T M -- Handelin, B L -- Housman, D E -- Evans, R M -- New York, N.Y. -- Science. 1987 Jul 17;237(4812):268-75.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3037703" target="_blank"〉PubMed〈/a〉

    RNA complementary to a herpesvirus alpha gene mRNA is prominent in latently infected neurons (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-02-27
    Description: In initial attempts to define the molecular events responsible for the latent state of herpes simplex virus, in situ hybridization was utilized to search for virally encoded RNA transcripts in latently infected sensory neurons. The use of cloned probes representing the entire viral genome indicated that transcripts encoded within terminal repeats were present. When the alpha genes encoding ICP-0, ICP-4, and ICP-27 and the gamma 1 gene encoding VP-5 were employed, only RNA transcripts hybridizing to the ICP-0 probe were detected. In latently infected cells, the ICP-0--related transcripts were localized principally in the nucleus; this was not the case in acutely (productively) infected neurons or in neurons probed for RNA transcripts coding for actin. In Northern blotting experiments, an RNA of 2.6 kilobases was detected with the ICP-0 probe. When single-stranded DNAs from the ICP-0 region were used as probes, RNA from the strand complementary to that encoding ICP-0 messenger RNA (mRNA) was the major species detected. This RNA species may play a significant role in maintaining the latent infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stevens, J G -- Wagner, E K -- Devi-Rao, G B -- Cook, M L -- Feldman, L T -- AI-06246/AI/NIAID NIH HHS/ -- CA 11861/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1987 Feb 27;235(4792):1056-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2434993" target="_blank"〉PubMed〈/a〉

    Amyloid beta protein gene: cDNA, mRNA distribution, and genetic linkage near the Alzheimer locus (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-02-20
    Description: The amyloid beta protein has been identified as an important component of both cerebrovascular amyloid and amyloid plaques of Alzheimer's disease and Down syndrome. A complementary DNA for the beta protein suggests that it derives from a larger protein expressed in a variety of tissues. Overexpression of the gene in brain tissue from fetuses with Down syndrome (trisomy 21) can be explained by dosage since the locus encoding the beta protein maps to chromosome 21. Regional localization of this gene by both physical and genetic mapping places it in the vicinity of the genetic defect causing the inherited form of Alzheimer's disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tanzi, R E -- Gusella, J F -- Watkins, P C -- Bruns, G A -- St George-Hyslop, P -- Van Keuren, M L -- Patterson, D -- Pagan, S -- Kurnit, D M -- Neve, R L -- AG00029/AG/NIA NIH HHS/ -- HD10658/HD/NICHD NIH HHS/ -- HD20118/HD/NICHD NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1987 Feb 20;235(4791):880-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2949367" target="_blank"〉PubMed〈/a〉

    The adenovirus major late transcription factor activates the rat gamma-fibrinogen promoter (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-10-30
    Description: The major late transcription factor (MLTF) is a 46-kilodalton polypeptide that specifically binds to and activates transcription from the major late promoter of adenovirus. The presence of this promoter-specific transcription factor in uninfected HeLa cell extracts suggests that MLTF is also involved in the transcription of cellular genes. This report demonstrates that MLTF specifically stimulates transcription of the rat gamma-fibrinogen gene through a high-affinity binding site. Stimulation of transcription by MLTF was not dependent on the exact position of the MLTF binding site with respect either to the transcription initiation site or to adjacent promoter elements. These results suggest that one of the cellular functions of MLTF is to control gamma-fibrinogen gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chodosh, L A -- Carthew, R W -- Morgan, J G -- Crabtree, G R -- Sharp, P A -- P01-CA42063/CA/NCI NIH HHS/ -- P30-CA14051/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1987 Oct 30;238(4827):684-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Massachusetts Institute of Technology, Cambridge 02139.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3672119" target="_blank"〉PubMed〈/a〉

    Allelic exclusion in transgenic mice that express the membrane form of immunoglobulin mu (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-05-15
    Description: Antibody-producing cells display a special form of regulation whereby each cell produces immunoglobulin from only one of its two sets of antibody genes. This phenomenon, called allelic exclusion, is thought to be mediated by the product of one heavy chain allele restricting the expression of the other. Heavy chains are synthesized in two molecular forms, secreted and membrane bound. In order to determine whether it is specifically the membrane-bound form of the immunoglobulin M (IgM) heavy chain (mu) that mediates this regulation, transgenic mice were created that carry a human mu chain gene altered so that it can only direct the synthesis of the membrane-bound protein. The membrane-bound form of the human mu chain was made by most of the B cells in these animals as measured by assays of messenger RNA and surface immunoglobulins. Further, the many B cells that express the human gene do not express endogenous mouse IgM, and the few B cells that express endogenous mouse mu do not express the transgene. Thus, the membrane-bound form of the mu chain is sufficient to mediate allelic exclusion. In addition, the molecular structures recognized for this purpose are conserved between human and mouse systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nussenzweig, M C -- Shaw, A C -- Sinn, E -- Danner, D B -- Holmes, K L -- Morse, H C 3rd -- Leder, P -- New York, N.Y. -- Science. 1987 May 15;236(4803):816-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3107126" target="_blank"〉PubMed〈/a〉

    Structural evidence for the authenticity of the human retinoblastoma gene (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-06-26
    Description: The retinoblastoma (Rb) gene is the prototype for a class of recessive human cancer genes in which loss of activity of both normal alleles is thought to be associated with tumorigenesis. Sixteen of 40 retinoblastomas examined with a complementary DNA probe shown to be the Rb gene had identifiable structural changes of the Rb gene including in some cases homozygous internal deletions with corresponding truncated transcripts. An osteosarcoma also had a homozygous internal deletion with a truncated transcript. In addition, possible hot spots for deletion were identified within the Rb genomic locus. Among those tumors with no identifiable structural changes there was either absence of an Rb transcript or abnormal expression of the Rb transcript. Comparison of the structural changes in the tumor cells and fibroblasts of certain patients provided support for Knudson's two-hit hypothesis for the development of retinoblastoma at the molecular level. The ability to detect germline structural deletions in fibroblasts from some patients with bilateral retinoblastoma also indicates that the isolated gene is useful for diagnostic purposes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fung, Y K -- Murphree, A L -- T'Ang, A -- Qian, J -- Hinrichs, S H -- Benedict, W F -- EY02715/EY/NEI NIH HHS/ -- EY0619502/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1987 Jun 26;236(4809):1657-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2885916" target="_blank"〉PubMed〈/a〉

    Diversity of alpha-fetoprotein gene expression in mice is generated by a combination of separate enhancer elements (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-01-02
    Description: The 5' flanking region of the mouse alpha-fetoprotein (AFP) gene contains a tissue-specific promoter and three upstream regulatory elements that behave as classical enhancers. At least one of these enhancers is now shown to be required for the tissue-specific expression of the AFP gene when it is introduced into the mouse genome by microinjection of cloned DNA fragments into fertilized eggs. Each enhancer can direct expression in the appropriate tissues, the visceral endoderm of the yolk sac, the fetal liver, and the gastrointestinal tract, but each exerts different influence in these three tissues. These differences may explain the tissue-specific diversity in the levels of expression characteristic of the AFP gene. The postnatal repression of transcription of the AFP gene in both liver and gut, as well as the reinitiation of its transcription during liver regeneration, is mimicked by the introduced gene when it is linked to the enhancer domains together or singly. Thus, the DNA sequence elements responsible for directing the activation of AFP transcription, its repression, and reinduction are contained in a limited segment of DNA within or 5' to the gene (or both) and are operative in the absence of the closely linked albumin gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hammer, R E -- Krumlauf, R -- Camper, S A -- Brinster, R L -- Tilghman, S M -- CA06927/CA/NCI NIH HHS/ -- CA28050/CA/NCI NIH HHS/ -- HD17321/HD/NICHD NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1987 Jan 2;235(4784):53-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2432657" target="_blank"〉PubMed〈/a〉
