    Early neocortical regionalization in the absence of thalamic innervation (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-08-07
    Description: There is a long-standing controversy regarding the mechanisms that generate the functional subdivisions of the cerebral neocortex. One model proposes that thalamic axonal input specifies these subdivisions; the competing model postulates that patterning mechanisms intrinsic to the dorsal telencephalon generate neocortical regions. Gbx-2 mutant mice, whose thalamic differentiation is disrupted, were investigated. Despite the lack of cortical innervation by thalamic axons, neocortical region-specific gene expression (Cadherin-6, EphA-7, Id-2, and RZR-beta) developed normally. This provides evidence that patterning mechanisms intrinsic to the neocortex specify the basic organization of its functional subdivisions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miyashita-Lin, E M -- Hevner, R -- Wassarman, K M -- Martinez, S -- Rubenstein, J L -- NS34661-01A1/NS/NINDS NIH HHS/ -- R01 MH49428-01/MH/NIMH NIH HHS/ -- R01 MH51561-01A1/MH/NIMH NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1999 Aug 6;285(5429):906-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Nina Ireland Laboratory of Developmental Neurobiology, Department of Psychiatry, School of Medicine, University of California San Francisco, San Francisco, CA 94143-0984, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10436162" target="_blank"〉PubMed〈/a〉

    Interaction of a Golgi-associated kinesin-like protein with Rab6 (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-02-07
    Description: Rab guanosine triphosphatases regulate vesicular transport and membrane traffic within eukaryotic cells. Here, a kinesin-like protein that interacts with guanosine triphosphate (GTP)-bound forms of Rab6 was identified. This protein, termed Rabkinesin-6, was localized to the Golgi apparatus and shown to play a role in the dynamics of this organelle. The carboxyl-terminal domain of Rabkinesin-6, which contains the Rab6-interacting domain, inhibited the effects of Rab6-GTP on intracellular transport. Thus, a molecular motor is a potential effector of a Rab protein, and coordinated action between members of these two families of proteins could control membrane dynamics and directional vesicular traffic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Echard, A -- Jollivet, F -- Martinez, O -- Lacapere, J J -- Rousselet, A -- Janoueix-Lerosey, I -- Goud, B -- New York, N.Y. -- Science. 1998 Jan 23;279(5350):580-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Unite Mixte de Recherche CNRS 144 et 168, Institut Curie, 26 rue d'Ulm, 75248 Paris Cedex 05, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9438855" target="_blank"〉PubMed〈/a〉

    Size variation in Middle Pleistocene humans (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-08-22
    Description: It has been suggested that European Middle Pleistocene humans, Neandertals, and prehistoric modern humans had a greater sexual dimorphism than modern humans. Analysis of body size variation and cranial capacity variation in the large sample from the Sima de los Huesos site in Spain showed instead that the sexual dimorphism is comparable in Middle Pleistocene and modern populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arsuaga, J L -- Carretero, J M -- Lorenzo, C -- Gracia, A -- Martinez, I -- Bermudez de Castro, J M -- Carbonell, E -- New York, N.Y. -- Science. 1997 Aug 22;277(5329):1086-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departamento de Paleontologia, Instituto de Geologia Economica, Facultad de Ciencias Geologicas, Universidad Complutense de Madrid, Ciudad Universitaria 28040 Madrid, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9262474" target="_blank"〉PubMed〈/a〉

    A hominid from the lower Pleistocene of Atapuerca, Spain: possible ancestor to Neandertals and modern humans (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-05-30
    Description: Human fossil remains recovered from the TD6 level (Aurora stratum) of the lower Pleistocene cave site of Gran Dolina, Sierra de Atapuerca, Spain, exhibit a unique combination of cranial, mandibular, and dental traits and are suggested as a new species of Homo-H. antecessor sp. nov. The fully modern midfacial morphology of the fossils antedates other evidence of this feature by about 650, 000 years. The midfacial and subnasal morphology of modern humans may be a retention of a juvenile pattern that was not yet present in H. ergaster. Homo antecessor may represent the last common ancestor for Neandertals and modern humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bermudez de Castro, J M -- Arsuaga, J L -- Carbonell, E -- Rosas, A -- Martinez, I -- Mosquera, M -- New York, N.Y. -- Science. 1997 May 30;276(5317):1392-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Museo Nacional de Ciencias Naturales, Consejo Superior de Investigaciones Cientificas (CSIC), Departamento de Paleobiologia, J.
