    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〉

    Identification of a thyroid hormone receptor that is pituitary-specific (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-04-07
    Description: Three cellular homologs of the v-erbA oncogene were previously identified in the rat; two of them encode high affinity receptors for the thyroid hormone triiodothyronine (T3). A rat complementary DNA clone encoding a T3 receptor form of the ErbA protein, called r-ErbA beta-2, was isolated. The r-ErbA beta-2 protein differs at its amino terminus from the previously described rat protein encoded by c-erbA beta and referred to as r-ErbA beta-1. Unlike the other members of the c-erbA proto-oncogene family, which have a wide tissue distribution, r-erbA beta-2 appears to be expressed only in the anterior pituitary gland. In addition, thyroid hormone downregulates r-erbA beta-2 messenger RNA but not r-erbA beta-1 messenger RNA in a pituitary tumor-derived cell line. The presence of a pituitary-specific form of the thyroid hormone receptor that may be selectively regulated by thyroid hormone could be important for the differential regulation of gene expression by T3 in the pituitary gland.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hodin, R A -- Lazar, M A -- Wintman, B I -- Darling, D S -- Koenig, R J -- Larsen, P R -- Moore, D D -- Chin, W W -- New York, N.Y. -- Science. 1989 Apr 7;244(4900):76-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Brigham and Women's Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2539642" target="_blank"〉PubMed〈/a〉

    Identification of human uromodulin as the Tamm-Horsfall urinary glycoprotein (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-04-03
    Description: The primary structure of human uromodulin, a 616-amino acid, 85-kilodalton glycoprotein with in vitro immunosuppressive properties, was determined through isolation and characterization of complementary DNA and genomic clones. The amino acid sequence encoded by one of the exons of the uromodulin gene has homology to the low-density-lipoprotein receptor and the epidermal growth factor precursor. Northern hybridization analyses demonstrate that uromodulin is synthesized by the kidney. Evidence is provided that uromodulin is identical to the previously characterized Tamm-Horsfall glycoprotein, the most abundant protein in normal human urine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pennica, D -- Kohr, W J -- Kuang, W J -- Glaister, D -- Aggarwal, B B -- Chen, E Y -- Goeddel, D V -- New York, N.Y. -- Science. 1987 Apr 3;236(4797):83-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3453112" target="_blank"〉PubMed〈/a〉

    Type-restricted neutralization of molecular clones of human immunodeficiency virus (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-07-15
    Description: In a study of the immunologic significance of the genetic diversity present within single isolates of human immunodeficiency virus type 1 (HIV-1), the neutralization of viruses derived from molecular clones of the HIV-1 strain HTLV-IIIB by an extensive panel of sera was compared. Sera from HIV-1-infected patients and from goats immunized with polyacrylamide gel-purified HIV-1 envelope glycoprotein (gp120), native gp120, or gp120-derived recombinant peptides, showed marked heterogeneity in neutralizing activity against these closely related viruses. The change of a single amino acid residue in gp120 may account for such "clonal restriction" of neutralizing activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Looney, D J -- Fisher, A G -- Putney, S D -- Rusche, J R -- Redfield, R R -- Burke, D S -- Gallo, R C -- Wong-Staal, F -- New York, N.Y. -- Science. 1988 Jul 15;241(4863):357-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Viral Diseases, Walter Reed Army Institute of Research, Washington, DC 20307.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3388046" target="_blank"〉PubMed〈/a〉

    T-cell receptor beta-chain expression: dependence on relatively few variable region genes (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-08-09
    Description: Fifteen independently isolated complementary DNA clones that contain T-cell receptor (TCR) V beta genes were sequenced and found to represent 11 different V beta genes. When compared with known sequences, 14 different V beta genes could be defined from a total of 25 complementary DNA's; 11 clones therefore involved repeated usage of previously identified V beta's. Based on these data, we calculate a maximum likelihood estimate of the number of expressed germline V beta genes to be 18 with an upper 95 percent confidence bound of 30 genes. Southern blot analysis has shown that most of these genes belong to single element subfamilies which show very limited interstrain polymorphism. The TCR beta-chain diversity appears to be generated from a limited V beta gene pool primarily by extensive variability at the variable-diversity-joining (V-D-J) junctional site, with no evidence for the involvement of somatic hypermutation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Behlke, M A -- Spinella, D G -- Chou, H S -- Sha, W -- Hartl, D L -- Loh, D Y -- GM07200/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1985 Aug 9;229(4713):566-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3875151" target="_blank"〉PubMed〈/a〉

    Studies of the human c-myb gene and its product in human acute leukemias (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-07-18
    Description: The myb gene is the transforming oncogene of the avian myeloblastosis virus (AMV); its normal cellular homolog, c-myb, is conserved across a broad span of evolution. In humans, c-myb is expressed in malignant hematopoietic cell lines and in primary hematopoietic tumors. Partial complementary DNA clones were generated from blast cells of patients with acute myelogenous leukemia. The sequences of the clones were compared to the c-myb of other species, as well as the v-myb of AMV. In addition, the carboxyl terminal region of human c-myb was placed in an expression vector to obtain protein for the generation of antiserum, which was used to identify the human c-myb gene product. Like v-myb, this protein was found within the nucleus of leukemic cells where it was associated with the nuclear matrix. These studies provide further evidence that c-myb might be involved in human leukemia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Slamon, D J -- Boone, T C -- Murdock, D C -- Keith, D E -- Press, M F -- Larson, R A -- Souza, L M -- CA36827/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 Jul 18;233(4761):347-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3014652" target="_blank"〉PubMed〈/a〉

    Loss of M2 muscarine receptors in the cerebral cortex in Alzheimer's disease and experimental cholinergic denervation (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-05-31
    Description: Cerebral cortex samples from patients with Alzheimer's disease and from rats after experimental cholinergic denervation of the cerebral cortex exhibited reductions in the presynaptic marker choline acetyltransferase activity and in the number of M2 muscarine receptors, with no change in the number of M1 receptors. These results are in keeping with evidence that M2 receptors function in cholinergic nerve terminals to regulate the release of acetylcholine, whereas M1 receptors are located on postsynaptic cells and facilitate cellular excitation. New M1-selective agonists and M2-selective antagonists directed at post- or presynaptic sites deserve consideration as potential agents for the treatment of the disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mash, D C -- Flynn, D D -- Potter, L T -- HLO-7188/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1985 May 31;228(4703):1115-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3992249" target="_blank"〉PubMed〈/a〉

    A "selfish" B chromosome that enhances its transmission by eliminating the paternal genome (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-04-22
    Description: In the parasitic wasp, Nasonia vitripennis, males are haploid and usually develop from unfertilized eggs, whereas females are diploid and develop from fertilized eggs. Some individuals in this species carry a genetic element, termed psr (paternal sex ratio), which is transmitted through sperm and causes condensation and subsequent loss of paternal chromosomes in fertilized eggs, thus converting diploid females into haploid males. In this report the psr trait was shown to be caused by a supernumerary chromosome. This B chromosome contains at least three repetitive DNA sequences that do not cross-hybridize to each other or to the host genome. The psr chromosome apparently produces a trans-acting product responsible for condensation of the paternal chromosomes, but is itself insensitive to the effect. Because the psr chromosome enhances its transmission by eliminating the rest of the genome, it can be considered the most "selfish" genetic element yet described.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nur, U -- Werren, J H -- Eickbush, D G -- Burke, W D -- Eickbush, T H -- GM31867/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1988 Apr 22;240(4851):512-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Rochester, NY 14627.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3358129" target="_blank"〉PubMed〈/a〉

    Vascular permeability factor, an endothelial cell mitogen related to PDGF (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-12-08
    Description: Vascular permeability factor (VPF) is a 40-kilodalton disulfide-linked dimeric glycoprotein that is active in increasing blood vessel permeability, endothelial cell growth, and angiogenesis. These properties suggest that the expression of VPF by tumor cells could contribute to the increased neovascularization and vessel permeability that are associated with tumor vasculature. The cDNA sequence of VPF from human U937 cells was shown to code for a 189-amino acid polypeptide that is similar in structure to the B chain of platelet-derived growth factor (PDGF-B) and other PDGF-B-related proteins. The overall identity with PDGF-B is 18%. However, all eight of the cysteines in PDGF-B were found to be conserved in human VPF, an indication that the folding of the two proteins is probably similar. Clusters of basic amino acids in the COOH-terminal halves of human VPF and PDGF-B are also prevalent. Thus, VPF appears to be related to the PDGF/v-sis family of proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keck, P J -- Hauser, S D -- Krivi, G -- Sanzo, K -- Warren, T -- Feder, J -- Connolly, D T -- New York, N.Y. -- Science. 1989 Dec 8;246(4935):1309-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Culture and Biochemistry, Monsanto Company, St. Louis, MO 63167.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2479987" target="_blank"〉PubMed〈/a〉

    Vascular endothelial growth factor is a secreted angiogenic mitogen (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-12-08
    Description: Vascular endothelial growth factor (VEGF) was purified from media conditioned by bovine pituitary folliculostellate cells (FC). VEGF is a heparin-binding growth factor specific for vascular endothelial cells that is able to induce angiogenesis in vivo. Complementary DNA clones for bovine and human VEGF were isolated from cDNA libraries prepared from FC and HL60 leukemia cells, respectively. These cDNAs encode hydrophilic proteins with sequences related to those of the A and B chains of platelet-derived growth factor. DNA sequencing suggests the existence of several molecular species of VEGF. VEGFs are secreted proteins, in contrast to other endothelial cell mitogens such as acidic or basic fibroblast growth factors and platelet-derived endothelial cell growth factor. Human 293 cells transfected with an expression vector containing a bovine or human VEGF cDNA insert secrete an endothelial cell mitogen that behaves like native VEGF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leung, D W -- Cachianes, G -- Kuang, W J -- Goeddel, D V -- Ferrara, N -- New York, N.Y. -- Science. 1989 Dec 8;246(4935):1306-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Genetech, South San Francisco, CA 94080.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2479986" target="_blank"〉PubMed〈/a〉
