    Gene expression during the life cycle of Drosophila melanogaster (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-09-28
    Description: Molecular genetic studies of Drosophila melanogaster have led to profound advances in understanding the regulation of development. Here we report gene expression patterns for nearly one-third of all Drosophila genes during a complete time course of development. Mutations that eliminate eye or germline tissue were used to further analyze tissue-specific gene expression programs. These studies define major characteristics of the transcriptional programs that underlie the life cycle, compare development in males and females, and show that large-scale gene expression data collected from whole animals can be used to identify genes expressed in particular tissues and organs or genes involved in specific biological and biochemical processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arbeitman, Michelle N -- Furlong, Eileen E M -- Imam, Farhad -- Johnson, Eric -- Null, Brian H -- Baker, Bruce S -- Krasnow, Mark A -- Scott, Matthew P -- Davis, Ronald W -- White, Kevin P -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2002 Sep 27;297(5590):2270-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Stanford University, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12351791" target="_blank"〉PubMed〈/a〉

    Linkage of plasma Abeta42 to a quantitative locus on chromosome 10 in late-onset Alzheimer's disease pedigrees (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-12-23
    Description: Plasma Abeta42 (amyloid beta42 peptide) is invariably elevated in early-onset familial Alzheimer's disease (AD), and it is also increased in the first-degree relatives of patients with typical late-onset AD (LOAD). To detect LOAD loci that increase Abeta42, we used plasma Abeta42 as a surrogate trait and performed linkage analysis on extended AD pedigrees identified through a LOAD patient with extremely high plasma Abeta. Here, we report linkage to chromosome 10 with a maximal lod score of 3.93 at 81 centimorgans close to D10S1225. Remarkably, linkage to the same region was obtained independently in a genome-wide screen of LOAD sibling pairs. These results provide strong evidence for a novel LOAD locus on chromosome 10 that acts to increase Abeta.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ertekin-Taner, N -- Graff-Radford, N -- Younkin, L H -- Eckman, C -- Baker, M -- Adamson, J -- Ronald, J -- Blangero, J -- Hutton, M -- Younkin, S G -- AG06656/AG/NIA NIH HHS/ -- MH59490/MH/NIMH NIH HHS/ -- P50 AG16574/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2000 Dec 22;290(5500):2303-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mayo Clinic Jacksonville, Jacksonville, FL 32224, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11125143" target="_blank"〉PubMed〈/a〉

    Matriarchs as repositories of social knowledge in African elephants (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-04-21
    Description: Despite widespread interest in the evolution of social intelligence, little is known about how wild animals acquire and store information about social companions or whether individuals possessing enhanced social knowledge derive biological fitness benefits. Using playback experiments on African elephants (Loxodonta africana), we demonstrated that the possession of enhanced discriminatory abilities by the oldest individual in a group can influence the social knowledge of the group as a whole. These superior abilities for social discrimination may result in higher per capita reproductive success for female groups led by older individuals. Our findings imply that the removal of older, more experienced individuals, which are often targets for hunters because of their large size, could have serious consequences for endangered populations of advanced social mammals such as elephants and whales.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McComb, K -- Moss, C -- Durant, S M -- Baker, L -- Sayialel, S -- New York, N.Y. -- Science. 2001 Apr 20;292(5516):491-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Experimental Psychology, School of Biological Sciences, University of Sussex, Brighton BN1 9QG, UK. karenm@biols.susx.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11313492" target="_blank"〉PubMed〈/a〉

    A new DNA marker tightly linked to the fragile X locus (FRAXA) (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-12-08
    Description: The fragile X syndrome is the most common cause of familial mental retardation. Genetic counseling and gene isolation are hampered by a lack of DNA markers close to the disease locus. Two somatic cell hybrids that each contain a human X chromosome with a breakpoint close to the fragile X locus have been characterized. A new DNA marker (DXS296) lies between the chromosome breakpoints and is the closest marker to the fragile X locus yet reported. The Hunter syndrome gene, which causes iduronate sulfatase deficiency, is located at the X chromosome breakpoint that is distal to this new marker, thus localizing the Hunter gene distal to the fragile X locus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suthers, G K -- Callen, D F -- Hyland, V J -- Kozman, H M -- Baker, E -- Eyre, H -- Harper, P S -- Roberts, S H -- Hors-Cayla, M C -- Davies, K E -- New York, N.Y. -- Science. 1989 Dec 8;246(4935):1298-300.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Histopathology, Adelaide Children's Hospital, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2573953" target="_blank"〉PubMed〈/a〉

    A multifunctional aqueous channel formed by CFTR (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-11-27
    Description: The cystic fibrosis gene product (CFTR) is a complex protein that functions as an adenosine 3,5-monophosphate (cAMP)-stimulated ion channel and possibly as a regulator of intracellular processes. In order to determine whether the CFTR molecule contains a functional aqueous pathway, anion, water, and urea transport were measured in Xenopus oocytes expressing CFTR. Cyclic AMP agonists induced a Cl- conductance of 94 microsiemens and an increase in water permeability of 4 x 10(-4) centimeter per second that was inhibited by a Cl- channel blocker and was dependent on anion composition. CFTR has a calculated single channel water conductance of 9 x 10(-13) cubic centimeter per second, suggesting a pore-like aqueous pathway. Oocytes expressing CFTR also showed cAMP-stimulated transport of urea but not the larger solute sucrose. Thus CFTR contains a cAMP-stimulated aqueous pore that can transport anions, water, and small solutes. The results also provide functional evidence for water movement through an ion channel.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hasegawa, H -- Skach, W -- Baker, O -- Calayag, M C -- Lingappa, V -- Verkman, A S -- DK35124/DK/NIDDK NIH HHS/ -- DK43840/DK/NIDDK NIH HHS/ -- HL42368/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1992 Nov 27;258(5087):1477-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of California, San Francisco 94143-0532.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1279809" target="_blank"〉PubMed〈/a〉

    K+ current diversity is produced by an extended gene family conserved in Drosophila and mouse (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-05-04
    Description: The Drosophila Shaker gene on the X chromosome has three sister genes, Shal, Shab, and Shaw, which map to the second and third chromosomes. This extended gene family encodes voltage-gated potassium channels with widely varying kinetics (rate of macroscopic current activation and inactivation) and voltage sensitivity of steady-state inactivation. The differences in the currents of the various gene products are greater than the differences produced by alternative splicing of the Shaker gene. In Drosophila, the transient (A current) subtype of the potassium channel (Shaker and Shal) and the delayed-rectifier subtype (Shab and Shaw) are encoded by homologous genes, and there is more than one gene for each subtype of channel. Homologs of Shaker, Shal, Shab, and Shaw are present in mammals; each Drosophila potassium-channel gene may be represented as a multigene subfamily in mammals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wei, A -- Covarrubias, M -- Butler, A -- Baker, K -- Pak, M -- Salkoff, L -- 1 RO1-NS24785-01/NS/NINDS NIH HHS/ -- GMO 7200/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 May 4;248(4955):599-603.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Neurobiology, 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/2333511" target="_blank"〉PubMed〈/a〉
