    Delocalization of Vg1 mRNA from the vegetal cortex in Xenopus oocytes after destruction of Xlsirt RNA (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-08-19
    Description: The Xlsirts are a family of transcribed repeat sequence genes that do not code for protein. Xlsirt RNAs become localized to the vegetal cortex of Xenopus oocytes early in oogenesis, before the localization of the messenger RNA Vg1, which encodes a transforming growth factor-beta-like molecule involved in mesoderm formation, and coincident with the localization of Xcat2 transcripts, which encode a nanos-like molecule. Destruction of the localized Xlsirts by injection of antisense oligodeoxynucleotides into stage 4 oocytes resulted in the release of Vg1 transcripts but not Xcat2 transcripts from the vegetal cortex. Xlsirt RNAs, which may be a structural component of the vegetal cortex, are a crucial part of a genetic pathway necessary for the proper localization of Vg1 that leads to subsequent normal pattern formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kloc, M -- Etkin, L D -- New York, N.Y. -- Science. 1994 Aug 19;265(5175):1101-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics, University of Texas, M.D. Anderson Cancer Center, Houston 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7520603" target="_blank"〉PubMed〈/a〉

    Functional participation of the IL-2 receptor gamma chain in IL-7 receptor complexes (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-03-11
    Description: The gamma chain of the interleukin-2 (IL-2) receptor is shared with the functional IL-4 receptor and is causatively related to X-linked severe combined immunodeficiency (XSCID), which is ascribed to a profound T cell defect. Studies with monoclonal antibodies specific for the IL-2 receptor gamma chain showed that the gamma chain participates in the functional high-affinity receptor complexes for IL-7 that are involved in the differentiation of T and B cells. Participation of the gamma subunit in more than one receptor may enable the elucidation of the mechanisms of XSCID development and lymphocyte differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kondo, M -- Takeshita, T -- Higuchi, M -- Nakamura, M -- Sudo, T -- Nishikawa, S -- Sugamura, K -- New York, N.Y. -- Science. 1994 Mar 11;263(5152):1453-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, Tohoku University School of Medicine, Sendai, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8128231" target="_blank"〉PubMed〈/a〉

    Thalamic abnormalities in schizophrenia visualized through magnetic resonance image averaging (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-10-14
    Description: Schizophrenia is a complex illness characterized by multiple types of symptoms involving many aspects of cognition and emotion. Most efforts to identify its underlying neural substrates have focused on a strategy that relates a single symptom to a single brain region. An alternative hypothesis, that the variety of symptoms could be explained by a lesion in midline neural circuits mediating attention and information processing, is explored. Magnetic resonance images from patients and controls were transformed with a "bounding box" to produce an "average schizophrenic brain" and an "average normal brain." After image subtraction of the two averages, the areas of difference were displayed as an effect size map. Specific regional abnormalities were observed in the thalamus and adjacent white matter. An abnormality in the thalamus and related circuitry explains the diverse symptoms of schizophrenia parsimoniously because they could all result from a defect in filtering or gating sensory input, which is one of the primary functions of the thalamus in the human brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andreasen, N C -- Arndt, S -- Swayze, V 2nd -- Cizadlo, T -- Flaum, M -- O'Leary, D -- Ehrhardt, J C -- Yuh, W T -- MH31593/MH/NIMH NIH HHS/ -- MH40856/MH/NIMH NIH HHS/ -- MHCRC 43271/MH/NIMH NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Oct 14;266(5183):294-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mental Health Clinical Research Center, College of Medicine.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7939669" target="_blank"〉PubMed〈/a〉

    GDNF: a potent survival factor for motoneurons present in peripheral nerve and muscle (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-11
    Description: For survival, embryonic motoneurons in vertebrates depend on as yet undefined neurotrophic factors present in the limb bud. Members of the neurotrophin family are currently the best candidates for such neurotrophic factors, but inactivation of their receptor genes leads to only partial loss of motoneurons, which suggests that other factors are involved. Glial cell line-derived neurotrophic factor (GDNF), originally identified as a trophic factor specific for dopaminergic neurons, was found to be 75-fold more potent than the neurotrophins in supporting the survival of purified embryonic rat motoneurons in culture. GDNF messenger RNA was found in the immediate vicinity of motoneurons during the period of cell death in development. In vivo, GDNF rescues and prevents the atrophy of facial motoneurons that have been deprived of target-derived survival factors by axotomy. GDNF may therefore be a physiological trophic factor for spinal motoneurons. Its potency and specificity in vitro and in vivo also make it a good candidate for treatment of motoneuron disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Henderson, C E -- Phillips, H S -- Pollock, R A -- Davies, A M -- Lemeulle, C -- Armanini, M -- Simmons, L -- Moffet, B -- Vandlen, R A -- Simpson LC corrected to Simmons, L -- Koliatsos, V E -- Rosenthal, A -- NS 10580/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 11;266(5187):1062-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM U.382, IBDM, Marseille, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973664" target="_blank"〉PubMed〈/a〉

    Detection of endogenous malondialdehyde-deoxyguanosine adducts in human liver (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-09-09
    Description: Endogenous DNA adducts may contribute to the etiology of human genetic disease and cancer. One potential source of endogenous DNA adducts is lipid peroxidation, which generates mutagenic carbonyl compounds such as malondialdehyde. A sensitive mass spectrometric method permitted detection and quantitation of the major malondialdehyde-DNA adduct, a pyrimidopurinone derived from deoxyguanosine. DNA from disease-free human liver was found to contain 5400 adducts per cell, a frequency comparable to that of adducts formed by exogenous carcinogens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chaudhary, A K -- Nokubo, M -- Reddy, G R -- Yeola, S N -- Morrow, J D -- Blair, I A -- Marnett, L J -- CA47479/CA/NCI NIH HHS/ -- ES00267/ES/NIEHS NIH HHS/ -- GM42056/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 9;265(5178):1580-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉A.

    Identification of herpesvirus-like DNA sequences in AIDS-associated Kaposi's sarcoma (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-16
    Description: Representational difference analysis was used to isolate unique sequences present in more than 90 percent of Kaposi's sarcoma (KS) tissues obtained from patients with acquired immunodeficiency syndrome (AIDS). These sequences were not present in tissue DNA from non-AIDS patients, but were present in 15 percent of non-KS tissue DNA samples from AIDS patients. The sequences are homologous to, but distinct from, capsid and tegument protein genes of the Gammaherpesvirinae, herpesvirus saimiri and Epstein-Barr virus. These KS-associated herpesvirus-like (KSHV) sequences appear to define a new human herpesvirus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, Y -- Cesarman, E -- Pessin, M S -- Lee, F -- Culpepper, J -- Knowles, D M -- Moore, P S -- New York, N.Y. -- Science. 1994 Dec 16;266(5192):1865-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, College of Physicians and Surgeons, Columbia University, New York, NY 10032.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7997879" target="_blank"〉PubMed〈/a〉

    Cooperative display and relatedness among males in a lek-mating bird (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-11
    Description: Long-tailed manakins mate in leks and cooperate in multiyear male-male partnerships. An alpha male is responsible for virtually all mating, whereas a beta male assists in the courtship displays. Such altruism by the beta male poses a problem for evolutionary theory because most theoretical treatments and empirical examples of cooperative behavior involve kin selection or reciprocity. Here it is shown that alpha and beta partners are not relatives and that reciprocity is not involved. Instead, direct, though long-delayed benefits to beta males are demonstrated, which include rare copulations, ascension to alpha status, and female lek fidelity. These benefits maintain this unusual form of male-male cooperation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McDonald, D B -- Potts, W K -- New York, N.Y. -- Science. 1994 Nov 11;266(5187):1030-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Archbold Biological Station, Lake Placid, FL 33852-2057.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973654" target="_blank"〉PubMed〈/a〉

    Genetic mapping of quantitative trait loci for growth and fatness in pigs (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-03-25
    Description: The European wild boar was crossed with the domesticated Large White pig to genetically dissect phenotypic differences between these populations for growth and fat deposition. The most important effects were clustered on chromosome 4, with a single region accounting for a large part of the breed difference in growth rate, fatness, and length of the small intestine. The study is an advance in genome analyses and documents the usefulness of crosses between divergent outbred populations for the detection and characterization of quantitative trait loci. The genetic mapping of a major locus for fat deposition in the pig could have implications for understanding human obesity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andersson, L -- Haley, C S -- Ellegren, H -- Knott, S A -- Johansson, M -- Andersson, K -- Andersson-Eklund, L -- Edfors-Lilja, I -- Fredholm, M -- Hansson, I -- New York, N.Y. -- Science. 1994 Mar 25;263(5154):1771-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Animal Breeding and Genetics, Swedish University of Agricultural Sciences, Uppsala.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8134840" target="_blank"〉PubMed〈/a〉

    Description: Estrogen hormones produce physiological actions within a variety of target sites in the body and during development by activating a specific receptor protein. Hormone responsiveness for the estrogen receptor protein was investigated at different stages of development with the use of gene knockout techniques because no natural genetic mutants have been described. A mutant mouse line without a functional estrogen receptor was created and is being used to assess estrogen responsiveness. Both sexes of these mutant animals are infertile and show a variety of phenotypic changes, some of which are associated with the gonads, mammary glands, reproductive tracts, and skeletal tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Korach, K S -- New York, N.Y. -- Science. 1994 Dec 2;266(5190):1524-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Receptor Biology Section, National Institute of Environmental Health Sciences, National Institutes of Health, Research Triangle Park, NC 27709.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7985022" target="_blank"〉PubMed〈/a〉

    Effect of the nigrostriatal dopamine system on acquired neural responses in the striatum of behaving monkeys (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-07-15
    Description: Dysfunction of the nigrostriatal dopamine system results in marked disorders of movement such as occur in Parkinson's disease. Functions of this dopamine-containing projection system were examined in monkeys trained in a classical conditioning task, and the effects of striatal dopamine depletion were tested. Unilateral dopamine loss substantially reduced the acquired sensory responsiveness of striatal neurons monitored electrophysiologically. This effect was ipsilateral and selective, and could be reversed by apomorphine. These results suggest that the primate nigrostriatal system modulates expression of neuronal response plasticity in the striatum during sensorimotor learning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aosaki, T -- Graybiel, A M -- Kimura, M -- R01 NS25529/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jul 15;265(5170):412-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology, Cambridge 02139.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8023166" target="_blank"〉PubMed〈/a〉

    Description: In a search for genes that regulate circadian rhythms in mammals, the progeny of mice treated with N-ethyl-N-nitrosourea (ENU) were screened for circadian clock mutations. A semidominant mutation, Clock, that lengthens circadian period and abolishes persistence of rhythmicity was identified. Clock segregated as a single gene that mapped to the midportion of mouse chromosome 5, a region syntenic to human chromosome 4. The power of ENU mutagenesis combined with the ability to clone murine genes by map position provides a generally applicable approach to study complex behavior in mammals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3839659/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3839659/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vitaterna, M H -- King, D P -- Chang, A M -- Kornhauser, J M -- Lowrey, P L -- McDonald, J D -- Dove, W F -- Pinto, L H -- Turek, F W -- Takahashi, J S -- P30-CA07175/CA/NCI NIH HHS/ -- R01-DK40493/DK/NIDDK NIH HHS/ -- T32 NS071040/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- etc. -- New York, N.Y. -- Science. 1994 Apr 29;264(5159):719-25.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology and Physiology, Northwestern University, Evanston, IL 60208.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171325" target="_blank"〉PubMed〈/a〉

    A genetic linkage map for the zebrafish (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-04-29
    Description: To facilitate molecular genetic analysis of vertebrate development, haploid genetics was used to construct a recombination map for the zebrafish Danio (Brachydanio) rerio. The map consists of 401 random amplified polymorphic DNAs (RAPDs) and 13 simple sequence repeats spaced at an average interval of 5.8 centimorgans. Strategies that exploit the advantages of haploid genetics and RAPD markers were developed that quickly mapped lethal and visible mutations and that placed cloned genes on the map. This map is useful for the position-based cloning of mutant genes, the characterization of chromosome rearrangements, and the investigation of evolution in vertebrate genomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Postlethwait, J H -- Johnson, S L -- Midson, C N -- Talbot, W S -- Gates, M -- Ballinger, E W -- Africa, D -- Andrews, R -- Carl, T -- Eisen, J S -- 1RO1AI26734/AI/NIAID NIH HHS/ -- HD07470/HD/NICHD NIH HHS/ -- NS23915/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Apr 29;264(5159):699-703.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Neurosciences, University of Oregon, Eugene 97403.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171321" target="_blank"〉PubMed〈/a〉

    Potential role of human cytomegalovirus and p53 interaction in coronary restenosis (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-07-15
    Description: A subset of patients who have undergone coronary angioplasty develop restenosis, a vessel renarrowing characterized by excessive proliferation of smooth muscle cells (SMCs). Of 60 human restenosis lesions examined, 23 (38 percent) were found to have accumulated high amounts of the tumor suppressor protein p53, and this correlated with the presence of human cytomegalovirus (HCMV) in the lesions. SMCs grown from the lesions expressed HCMV protein IE84 and high amounts of p53. HCMV infection of cultured SMCs enhanced p53 accumulation, which correlated temporally with IE84 expression. IE84 also bound to p53 and abolished its ability to transcriptionally activate a reporter gene. Thus, HCMV, and IE84-mediated inhibition of p53 function, may contribute to the development of restenosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Speir, E -- Modali, R -- Huang, E S -- Leon, M B -- Shawl, F -- Finkel, T -- Epstein, S E -- New York, N.Y. -- Science. 1994 Jul 15;265(5170):391-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cardiology Branch, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8023160" target="_blank"〉PubMed〈/a〉

    Effects of cerebral ischemia in mice deficient in neuronal nitric oxide synthase (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-09-23
    Description: The proposal that nitric oxide (NO) or its reactant products mediate toxicity in brain remains controversial in part because of the use of nonselective agents that block NO formation in neuronal, glial, and vascular compartments. In mutant mice deficient in neuronal NO synthase (NOS) activity, infarct volumes decreased significantly 24 and 72 hours after middle cerebral artery occlusion, and the neurological deficits were less than those in normal mice. This result could not be accounted for by differences in blood flow or vascular anatomy. However, infarct size in the mutant became larger after endothelial NOS inhibition by nitro-L-arginine administration. Hence, neuronal NO production appears to exacerbate acute ischemic injury, whereas vascular NO protects after middle cerebral artery occlusion. The data emphasize the importance of developing selective inhibitors of the neuronal isoform.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Z -- Huang, P L -- Panahian, N -- Dalkara, T -- Fishman, M C -- Moskowitz, M A -- NS10828/NS/NINDS NIH HHS/ -- NS2636/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 23;265(5180):1883-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Stroke Research Laboratory, Massachusetts General Hospital, Charlestown 02129.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7522345" target="_blank"〉PubMed〈/a〉

    Description: Many recent studies have implicated dietary factors in the cause and prevention of important diseases, including cancer, coronary heart disease, birth defects, and cataracts. There is strong evidence that vegetables and fruits protect against these diseases; however, the active constituents are incompletely identified. Whether fat per se is a major cause of disease is a question still under debate, although saturated and partially hydrogenated fats probably increase the risk of coronary heart disease. One clear conclusion from existing epidemiologic evidence is that many individuals in the United States have suboptimal diets and that the potential for disease prevention by improved nutrition is substantial.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willett, W C -- New York, N.Y. -- Science. 1994 Apr 22;264(5158):532-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Nutrition, Harvard School of Public Health, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8160011" target="_blank"〉PubMed〈/a〉

    Inhibition of hepatic chylomicron remnant uptake by gene transfer of a receptor antagonist (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-03
    Description: The low density lipoprotein receptor-related protein (LRP) has been proposed to mediate in concert with the LDL receptor (LDLR) the uptake of dietary lipoproteins into the hepatocytes. This hypothesis was tested by transient inactivation of LRP in vivo. Receptor-associated protein (RAP), a dominant negative regulator of LRP function, was transferred by an adenoviral vector to the livers of mice lacking LDLR (LDLR-/-). The inactivation of LRP by RAP was associated with a marked accumulation of chylomicron remnants in LDLR-/- mice and to a lesser degree in normal mice, suggesting that both LDLR and LRP are involved in remnant clearance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willnow, T E -- Sheng, Z -- Ishibashi, S -- Herz, J -- HL20948/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 3;264(5164):1471-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics, University of Texas Southwestern Medical Center, Dallas 75235.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7515194" target="_blank"〉PubMed〈/a〉

    Degeneration of a nonrecombining chromosome (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-01-14
    Description: Comparative studies suggest that sex chromosomes begin as ordinary autosomes that happen to carry a major sex determining locus. Over evolutionary time the Y chromosome is selected to stop recombining with the X chromosome, perhaps in response to accumulation of alleles beneficial to the heterogametic but harmful to the homogametic sex. Population genetic theory predicts that a nonrecombining Y chromosome should degenerate. Here this prediction is tested by application of specific selection pressures to Drosophila melanogaster populations. Results demonstrate the decay of a nonrecombining, nascent Y chromosome and the capacity for recombination to ameliorate such decay.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rice, W R -- New York, N.Y. -- Science. 1994 Jan 14;263(5144):230-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of California, Santa Cruz 95064.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8284674" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1994-09-30
    Description: A small proportion of breast cancer, in particular those cases arising at a young age, is due to the inheritance of dominant susceptibility genes conferring a high risk of the disease. A genomic linkage search was performed with 15 high-risk breast cancer families that were unlinked to the BRCA1 locus on chromosome 17q21. This analysis localized a second breast cancer susceptibility locus, BRCA2, to a 6-centimorgan interval on chromosome 13q12-13. Preliminary evidence suggests that BRCA2 confers a high risk of breast cancer but, unlike BRCA1, does not confer a substantially elevated risk of ovarian cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wooster, R -- Neuhausen, S L -- Mangion, J -- Quirk, Y -- Ford, D -- Collins, N -- Nguyen, K -- Seal, S -- Tran, T -- Averill, D -- CA-48711/CA/NCI NIH HHS/ -- CN-05222/CN/NCI NIH HHS/ -- HG-00571/HG/NHGRI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Sep 30;265(5181):2088-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Molecular Carcinogenesis, Institute of Cancer Research, Sutton, Surrey, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8091231" target="_blank"〉PubMed〈/a〉

    The Drosophila saxophone gene: a serine-threonine kinase receptor of the TGF-beta superfamily (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-03-25
    Description: The Drosophila decapentaplegic (dpp) gene encodes a transforming growth factor-beta (TGF-beta)-like protein that plays a key role in several aspects of development. Transduction of the DPP signal was investigated by cloning of serine-threonine kinase transmembrane receptors from Drosophila because this type of receptor is specific for the TGF-beta-like ligands. Here evidence is provided demonstrating that the Drosophila saxophone (sax) gene, a previously identified female sterile locus, encodes a TGF-beta-like type I receptor. Embryos from sax mothers and dpp embryos exhibit similar mutant phenotypes during early gastrulation, and these two loci exhibit genetic interactions, which suggest that they are utilized in the same pathway. These data suggest that sax encodes a receptor for dpp.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xie, T -- Finelli, A L -- Padgett, R W -- New York, N.Y. -- Science. 1994 Mar 25;263(5154):1756-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Waksman Institute, Rutgers University, Piscataway, NJ 08855-0759.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8134837" target="_blank"〉PubMed〈/a〉

    Description: Although sexual isolation is one of the most important causes of speciation, its genetic basis is largely unknown. Here evidence is presented that suggests that sexual isolation between two closely related species of Drosophila is largely caused by differences in female cuticular hydrocarbons. This difference maps to only one of the three major chromosomes, implying that reproductive isolation might have a fairly simple genetic basis. The effect of the hydrocarbons on courtship may help explain the ubiquitous asymmetry of sexual isolation between many pairs of Drosophila species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coyne, J A -- Crittenden, A P -- Mah, K -- GM 38462/GM/NIGMS NIH HHS/ -- GM 50355/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 2;265(5177):1461-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8073292" target="_blank"〉PubMed〈/a〉

    Autoantibodies to glutamate receptor GluR3 in Rasmussen's encephalitis (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-07-29
    Description: Rasmussen's encephalitis is a progressive childhood disease of unknown cause characterized by severe epilepsy, hemiplegia, dementia, and inflammation of the brain. During efforts to raise antibodies to recombinant glutamate receptors (GluRs), behaviors typical of seizures and histopathologic features mimicking Rasmussen's encephalitis were found in two rabbits immunized with GluR3 protein. A correlation was found between the presence of Rasmussen's encephalitis and serum antibodies to GluR3 detected by protein immunoblot analysis and by immunoreactivity to transfected cells expressing GluR3. Repeated plasma exchanges in one seriously ill child transiently reduced serum titers of GluR3 antibodies, decreased seizure frequency, and improved neurologic function. Thus, GluR3 is an autoantigen in Rasmussen's encephalitis, and an autoimmune process may underlie this disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rogers, S W -- Andrews, P I -- Gahring, L C -- Whisenand, T -- Cauley, K -- Crain, B -- Hughes, T E -- Heinemann, S F -- McNamara, J O -- NS17771/NS/NINDS NIH HHS/ -- NS28709/NS/NINDS NIH HHS/ -- NS30990R29/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Jul 29;265(5172):648-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Salt Lake City Geriatric Research Education and Clinical Center, Veterans Affairs Medical Center, UT.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8036512" target="_blank"〉PubMed〈/a〉

    The thermal grill illusion: unmasking the burn of cold pain (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-07-08
    Description: In Thunberg's thermal grill illusion, first demonstrated in 1896, a sensation of strong, often painful heat is elicited by touching interlaced warm and cool bars to the skin. Neurophysiological recordings from two classes of ascending spinothalamic tract neurons that are sensitive to innocuous or noxious cold showed differential responses to the grill. On the basis of these results, a simple model of central disinhibition, or unmasking, predicted a quantitative correspondence between grill-evoked pain and cold-evoked pain, which was verified psychophysically. This integration of pain and temperature can explain the thermal grill illusion and the burning sensation of cold pain and may also provide a basis for the cold-evoked, burning pain of the classic thalamic pain syndrome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Craig, A D -- Bushnell, M C -- DA07402/DA/NIDA NIH HHS/ -- NS25616/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jul 8;265(5169):252-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neurobiology, Barrow Neurological Institute, Phoenix, AZ 85013.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8023144" target="_blank"〉PubMed〈/a〉

    Specification of C/EBP function during Drosophila development by the bZIP basic region (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-16
    Description: The biologically relevant interactions of a transcription factor are those that are important for function in the organism. Here, a transgenic rescue assay was used to determine which molecular functions of Drosophila CCAAT/enhancer binding protein (C/EBP), a basic region-leucine zipper transcription factor, are required for it to fulfill its essential role during development. Chimeric proteins that contain the Drosophila C/EBP (DmC/EBP) basic region, a heterologous zipper, and a heterologous activation domain could functionally substitute for DmC/EBP. Mammalian C/EBPs were also functional in Drosophila. In contrast, 9 of 25 single amino acid substitutions in the basic region disrupted biological function. Thus, the conserved basic region specifies DmC/EBP activity in the organism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rorth, P -- New York, N.Y. -- Science. 1994 Dec 16;266(5192):1878-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Embryology, Carnegie Institution of Washington, Baltimore, MD 21210.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7997882" target="_blank"〉PubMed〈/a〉

    Fusion of a kinase gene, ALK, to a nucleolar protein gene, NPM, in non-Hodgkin's lymphoma (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-03-04
    Description: The 2;5 chromosomal translocation occurs in most anaplastic large-cell non-Hodgkin's lymphomas arising from activated T lymphocytes. This rearrangement was shown to fuse the NPM nucleolar phosphoprotein gene on chromosome 5q35 to a previously unidentified protein tyrosine kinase gene, ALK, on chromosome 2p23. In the predicted hybrid protein, the amino terminus of nucleophosmin (NPM) is linked to the catalytic domain of anaplastic lymphoma kinase (ALK). Expressed in the small intestine, testis, and brain but not in normal lymphoid cells, ALK shows greatest sequence similarity to the insulin receptor subfamily of kinases. Unscheduled expression of the truncated ALK may contribute to malignant transformation in these lymphomas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morris, S W -- Kirstein, M N -- Valentine, M B -- Dittmer, K G -- Shapiro, D N -- Saltman, D L -- Look, A T -- CA 21765/CA/NCI NIH HHS/ -- KO8 CA 01702/CA/NCI NIH HHS/ -- P01 CA 20180/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Mar 4;263(5151):1281-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Experimental Oncology, St. Jude Children's Research Hospital, Memphis, TN 38105.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8122112" target="_blank"〉PubMed〈/a〉

    A molecular determinant for submillisecond desensitization in glutamate receptors (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-11
    Description: The decay of excitatory postsynaptic currents in central neurons mediated by alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionate (AMPA) receptors is likely to be shaped either by receptor desensitization or by offset after removal of glutamate from the synaptic cleft. Native AMPA receptors show desensitization time constants of 1 to about 10 milliseconds, but the underlying molecular determinants of these large differences are unknown. Cloned AMPA receptors carrying the "flop" splice variants of glutamate receptor subtype C (GluR-C) and GluR-D are shown to have desensitization time constants of around 1 millisecond, whereas those with the "flip" variants are about four times slower. Cerebellar granule cells switch their expression of GluR-D splice variants from mostly flip forms in early stages to predominantly flop forms in the adult rat brain. These findings suggest that rapid desensitization of AMPA receptors can be regulated by the expression and alternative splicing of GluR-D gene transcripts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mosbacher, J -- Schoepfer, R -- Monyer, H -- Burnashev, N -- Seeburg, P H -- Ruppersberg, J P -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1994 Nov 11;266(5187):1059-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur medizinische Forschung, Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973663" target="_blank"〉PubMed〈/a〉

    Nitric oxide activation of poly(ADP-ribose) synthetase in neurotoxicity (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-02-04
    Description: Poly(adenosine 5'-diphosphoribose) synthetase (PARS) is a nuclear enzyme which, when activated by DNA strand breaks, adds up to 100 adenosine 5'-diphosphoribose (ADP-ribose) units to nuclear proteins such as histones and PARS itself. This activation can lead to cell death through depletion of beta-nicotinamide adenine dinucleotide (the source of ADP-ribose) and adenosine triphosphate. Nitric oxide (NO) stimulated ADP-ribosylation of PARS in rat brain. Benzamide and other derivatives, which inhibit PARS, blocked N-methyl-D-aspartate- and NO-mediated neurotoxicity with relative potencies paralleling their ability to inhibit PARS. Thus, NO appeared to elicit neurotoxicity by activating PARS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, J -- Dawson, V L -- Dawson, T M -- Snyder, S H -- DA-00074/DA/NIDA NIH HHS/ -- DA-00266/DA/NIDA NIH HHS/ -- DA-271-90-7408/DA/NIDA NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Feb 4;263(5147):687-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience, Johns Hopkins University School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8080500" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1994-12-02
    Description: The mammalian embryo cannot develop without the placenta. Its specialized cells (trophoblast, endoderm, and extraembryonic mesoderm) form early in development. They attach the embryo to the uterus (implantation) and form vascular connections necessary for nutrient transport. In addition, the placenta redirects maternal endocrine, immune, and metabolic functions to the embryo's advantage. These complex activities are sensitive to disruption, as shown by the high incidence of early embryonic mortality and pregnancy diseases in humans, as well as the numerous peri-implantation lethal mutations in mice. Integration of molecular and developmental approaches has recently produced insights into the molecules that control these processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cross, J C -- Werb, Z -- Fisher, S J -- HD 22210/HD/NICHD NIH HHS/ -- HD 26732/HD/NICHD NIH HHS/ -- HD 30367/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 2;266(5190):1508-18.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Samuel Lunenfeld Research Institute, Mount Sinai Hospital, Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7985020" target="_blank"〉PubMed〈/a〉

    Publication Date: 1994-01-28
    Description: As changes in synaptic strength are thought to be critical for learning and memory, it would be useful to monitor the activity of individual identified synapses on mammalian central neurons. Calcium imaging of cortical neurons grown in primary culture was used to visualize the activation of individual postsynaptic elements by miniature excitatory synaptic currents elicited by spontaneous quantal release. This approach revealed that the probability of spontaneous activity differed among synapses on the same dendrite. Furthermore, synapses that undergo changes in activity induced by glutamate or phorbol ester treatment were identified.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Murphy, T H -- Baraban, J M -- Wier, W G -- Blatter, L A -- New York, N.Y. -- Science. 1994 Jan 28;263(5146):529-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience, Johns Hopkins University School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7904774" target="_blank"〉PubMed〈/a〉

    Implications of FRA16A structure for the mechanism of chromosomal fragile site genesis (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-24
    Description: Fragile sites are chemically induced nonstaining gaps in chromosomes. Different fragile sites vary in frequency in the population and in the chemistry of their induction. DNA sequences encompassing and including the rare, autosomal, folate-sensitive fragile site, FRA16A, were isolated by positional cloning. The molecular basis of FRA16A was found to be expansion of a normally polymorphic p(CCG)n repeat. This repeat was adjacent to a CpG island that was methylated in fragile site-expressing individuals. The FRA16A locus in individuals who do not express the fragile site is not a site of DNA methylation (imprinting), which suggests that the methylation associated with fragile sites may be a consequence and not a cause of their genesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nancarrow, J K -- Kremer, E -- Holman, K -- Eyre, H -- Doggett, N A -- Le Paslier, D -- Callen, D F -- Sutherland, G R -- Richards, R I -- New York, N.Y. -- Science. 1994 Jun 24;264(5167):1938-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cytogenetics and Molecular Genetics, Women's and Children's Hospital, North Adelaide, South Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8009225" target="_blank"〉PubMed〈/a〉

    Direct signaling from astrocytes to neurons in cultures of mammalian brain cells (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-03-25
    Description: Although astrocytes have been considered to be supportive, rather than transmissive, in the adult nervous system, recent studies have challenged this assumption by demonstrating that astrocytes possess functional neurotransmitter receptors. Astrocytes are now shown to directly modulate the free cytosolic calcium, and hence transmission characteristics, of neighboring neurons. When a focal electric field potential was applied to single astrocytes in mixed cultures of rat forebrain astrocytes and neurons, a prompt elevation of calcium occurred in the target cell. This in turn triggered a wave of calcium increase, which propagated from astrocyte to astrocyte. Neurons resting on these astrocytes responded with large increases in their concentration of cytosolic calcium. The gap junction blocker octanol attenuated the neuronal response, which suggests that the astrocytic-neuronal signaling is mediated through intercellular connections rather than synaptically. This neuronal response to local astrocytic stimulation may mediate local intercellular communication within the brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nedergaard, M -- New York, N.Y. -- Science. 1994 Mar 25;263(5154):1768-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Surgery, Cornell University Medical College, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8134839" target="_blank"〉PubMed〈/a〉

The necessary vaccine efficacy levels and population coverage levels for eradication are quantified. The likely impact of risk behavior changes on vaccination campaigns is assessed. The results show it is unlikely that vaccines will be able to eradicate HIV in San Francisco unless they are combined with considerable reductions in risk behaviors. Furthermore, if risk behavior increases as the result of a vaccination campaign, then vaccination could result in a perverse outcome by increasing the severity of the epidemic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blower, S M -- McLean, A R -- 1R29DA08153/DA/NIDA NIH HHS/ -- AI33831/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 2;265(5177):1451-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Epidemiology Department, School of Public Health, University of California at Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8073289" target="_blank"〉PubMed〈/a〉

    Forward and reverse genetic approaches to behavior in the mouse (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-17
    Description: Modern molecular genetic and genomic approaches are revolutionizing the study of behavior in the mouse. "Reverse genetics" (from gene to phenotype) with targeted gene transfer provides a powerful tool to dissect behavior and has been used successfully to study the effects of null mutations in genes implicated in the regulation of long-term potentiation and spatial learning in mice. In addition, "forward genetics" (from phenotype to gene) with high-efficiency mutagenesis in the mouse can uncover unknown genes and has been used to isolate a behavioral mutant of the circadian system. With the recent availability of high-density genetic maps and physical mapping resources, positional cloning of virtually any mutation is now feasible in the mouse. Together, these approaches permit a molecular analysis of both known and previously unknown genes regulating behavior.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3830945/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3830945/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takahashi, J S -- Pinto, L H -- Vitaterna, M H -- EY08467/EY/NEI NIH HHS/ -- MH39592/MH/NIMH NIH HHS/ -- MH49241/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- etc. -- New York, N.Y. -- Science. 1994 Jun 17;264(5166):1724-33.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology and Physiology, Northwestern University, Evanston, IL 60208.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8209253" target="_blank"〉PubMed〈/a〉

    Requirement of a critical period of transcription for induction of a late phase of LTP (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-08-19
    Description: Repeated high-frequency trains of stimuli induce long-term potentiation (LTP) in the CA1 region that persists for up to 8 hours in hippocampal slices and for days in intact animals. This long time course has made LTP an attractive model for certain forms of long-term memory in the mammalian brain. A hallmark of long-term memory in the intact animal is a requirement for transcription, and thus whether the late phase of LTP (L-LTP) requires transcription was investigated here. With the use of different inhibitors, it was found in rat hippocampal slices that the induction of L-LTP [produced either by tetanic stimulation or by application of the cyclic adenosine monophosphate (cAMP) analog Sp-cAMPS (Sp-cyclic adenosine 3',5'-monophosphorothioate)] was selectively prevented when transcription was blocked immediately after tetanization or during application of cAMP. As with behavioral memory, this requirement for transcription had a critical time window. Thus, the late phase of LTP in the CA1 region requires transcription during a critical period, perhaps because cAMP-inducible genes must be expressed during this period.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nguyen, P V -- Abel, T -- Kandel, E R -- GM32099/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Aug 19;265(5175):1104-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, New York, NY.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8066450" target="_blank"〉PubMed〈/a〉

    Fas and perforin pathways as major mechanisms of T cell-mediated cytotoxicity (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-07-22
    Description: Two molecular mechanisms of T cell-mediated cytotoxicity, one perforin-based, the other Fas-based, have been demonstrated. To determine the extent of their contribution to T cell-mediated cytotoxicity, a range of effector cells from normal control or perforin-deficient mice were tested against a panel of target cells with various levels of Fas expression. All cytotoxicity observed was due to either of these mechanisms, and no third mechanism was detected. Thus, the perforin- and Fas-based mechanisms may account for all T cell-mediated cytotoxicity in short-term in vitro assays.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kagi, D -- Vignaux, F -- Ledermann, B -- Burki, K -- Depraetere, V -- Nagata, S -- Hengartner, H -- Golstein, P -- New York, N.Y. -- Science. 1994 Jul 22;265(5171):528-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, University of Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7518614" target="_blank"〉PubMed〈/a〉

    Enhanced aggressive behavior in mice lacking 5-HT1B receptor (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-09-23
    Description: The neuromodulator serotonin (5-hydroxytryptamine, 5-HT) has been associated with mood disorders such as depression, anxiety, and impulsive violence. To define the contribution of 5-HT receptor subtypes to behavior, mutant mice lacking the 5-HT1B receptor were generated by homologous recombination. These mice did not exhibit any obvious developmental or behavioral defects. However, the hyperlocomotor effect of the 5-HT1A/1B agonist RU24969 was absent in mutant mice, indicating that this effect is mediated by 5-HT1B receptors. Moreover, when confronted with an intruder, mutant mice attacked the intruder faster and more intensely than did wild-type mice, suggesting the participation of 5-HT1B receptors in aggressive behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saudou, F -- Amara, D A -- Dierich, A -- LeMeur, M -- Ramboz, S -- Segu, L -- Buhot, M C -- Hen, R -- New York, N.Y. -- Science. 1994 Sep 23;265(5180):1875-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de Genetique Moleculaire des Eucaryotes du CNRS, U184 de l'INSERM, Faculte de Medecine, Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8091214" target="_blank"〉PubMed〈/a〉

    Modulation of epithelial cell growth by intraepithelial gamma delta T cells (1994)

    Details
    Publication Date: 1994-11-18
    Description: The role played in immune surveillance by gamma delta T cells residing in various epithelia has not been clear. It is shown here that activated gamma delta T cells obtained from skin and intestine express the epithelial cell mitogen keratinocyte growth factor (KGF). In contrast, intraepithelial alpha beta T cells, as well as all lymphoid alpha beta and gamma delta T cell populations tested, did not produce KGF or promote the growth of cultured epithelial cells. These results suggest that intraepithelial gamma delta T cells function in surveillance and in repair of damaged epithelial tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boismenu, R -- Havran, W L -- AI32751/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 18;266(5188):1253-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Scripps Research Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973709" target="_blank"〉PubMed〈/a〉

    Description: The population of the developing world is currently expanding at the unprecedented rate of more than 800 million per decade, and despite anticipated reductions in growth during the 21st century, its size is expected to increase from 4.3 billion today to 10.2 billion in 2100. Past efforts to curb this growth have almost exclusively focused on the implementation of family planning programs to provide contraceptive information, services, and supplies. These programs have been partially successful in reducing birth rates. Further investments in them will have an additional but limited impact on population growth; therefore, other policy options, in particular measures to reduce high demand for births and limit population momentum, are needed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bongaarts, J -- New York, N.Y. -- Science. 1994 Feb 11;263(5148):771-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Division, Population Council, New York, NY 10017.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303293" target="_blank"〉PubMed〈/a〉

    Regulation of melanin biosynthesis in the human epidermis by tetrahydrobiopterin (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-03-11
    Description: The participation of (6R) 5,6,7,8-tetrahydrobiopterin (6-BH4) in regulating the tyrosine supply for melanin biosynthesis was investigated by the examination of human keratinocytes, melanocytes, and epidermal suction blisters from normal human skin and from patients with the depigmentation disorder vitiligo. Cells, as well as total epidermis, contained high phenylalanine hydroxylase activities and also displayed the capacity to synthesize and recycle 6-BH4, the essential cofactor for this enzyme. In vitiligo, 4a-hydroxy-BH4 dehydratase activity was extremely low or absent, yielding an accumulation of the nonenzymatic by-product 7-tetrahydrobiopterin (7-BH4) at concentrations up to 8 x 10(-6) M in the epidermis. This by-product is a potent competitive inhibitor in the phenylalanine hydroxylase reaction with an inhibition constant of 10(-6) M. Thus, 6-BH4 seems to control melanin biosynthesis in the human epidermis, whereas 7-BH4 may initiate depigmentation in patients with vitiligo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schallreuter, K U -- Wood, J M -- Pittelkow, M R -- Gutlich, M -- Lemke, K R -- Rodl, W -- Swanson, N N -- Hitzemann, K -- Ziegler, I -- New York, N.Y. -- Science. 1994 Mar 11;263(5152):1444-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Dermatology, University of Hamburg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8128228" target="_blank"〉PubMed〈/a〉

    Publication Date: 1994-09-30
    Description: Nucleotide sequence information derived from DNA segments of the human and other genomes is accumulating rapidly. However, it frequently proves difficult to use such short DNA segments to identify clones in genomic libraries or fragments in blots of the whole genome or for in situ analysis of chromosomes. Oligonucleotide probes, consisting of two target-complementary segments, connected by a linker sequence, were designed. Upon recognition of the specific nucleic acid molecule the ends of the probes were joined through the action of a ligase, creating circular DNA molecules catenated to the target sequence. These probes thus provide highly specific detection with minimal background.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nilsson, M -- Malmgren, H -- Samiotaki, M -- Kwiatkowski, M -- Chowdhary, B P -- Landegren, U -- New York, N.Y. -- Science. 1994 Sep 30;265(5181):2085-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Beijer Laboratory, Department of Medical Genetics, Biomedical Center, Uppsala, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7522346" target="_blank"〉PubMed〈/a〉

    Description: Deletions and other genome rearrangements can be caused by radiation and are associated with carcinogenesis and inheritable diseases. The pink-eyed unstable (p(un)) mutation in the mouse is caused by a gene duplication and reverts to wild type by deletion of one copy. Reversion events in the mouse embryo were detected as black spots on the fur of the animals or microscopically as partially black hair in a background of colorless hair. The frequency of partially black hair was increased by x-rays at very low doses. A linear dose-response relation was found between 1 and 100 centigray.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schiestl, R H -- Khogali, F -- Carls, N -- ES06593/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 2;266(5190):1573-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Toxicology, Harvard School of Public Health, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7985029" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1994-06-10
    Description: In spite of recent advances in identifying genes causing monogenic human disease, very little is known about the genes involved in polygenic disease. Three families were identified with mutations in the unlinked photoreceptor-specific genes ROM1 and peripherin/RDS, in which only double heterozygotes develop retinitis pigmentosa (RP). These findings indicate that the allelic and nonallelic heterogeneity known to be a feature of monogenic RP is complicated further by interactions between unlinked mutations causing digenic RP. Recognition of the inheritance pattern exemplified by these three families might facilitate the identification of other examples of digenic inheritance in human disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kajiwara, K -- Berson, E L -- Dryja, T P -- EY00169/EY/NEI NIH HHS/ -- EY08683/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 10;264(5165):1604-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Berman-Gund Laboratory for the Study of Retinal Degenerations, Harvard Medical School, Massachusetts Eye and Ear Infirmary, Boston 02114.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8202715" target="_blank"〉PubMed〈/a〉

    Requirement of human renal water channel aquaporin-2 for vasopressin-dependent concentration of urine (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-04-01
    Description: Concentration of urine in mammals is regulated by the antidiuretic hormone vasopressin. Binding of vasopressin to its V2 receptor leads to the insertion of water channels in apical membranes of principal cells in collecting ducts. In nephrogenic diabetes insipidus (NDI), the kidney fails to concentrate urine in response to vasopressin. A male patient with an autosomal recessive form of NDI was found to be a compound heterozygote for two mutations in the gene encoding aquaporin-2, a water channel. Functional expression studies in Xenopus oocytes revealed that each mutation resulted in nonfunctional water channel proteins. Thus, aquaporin-2 is essential for vasopressin-dependent concentration of urine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deen, P M -- Verdijk, M A -- Knoers, N V -- Wieringa, B -- Monnens, L A -- van Os, C H -- van Oost, B A -- New York, N.Y. -- Science. 1994 Apr 1;264(5155):92-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Physiology, University of Nijmegen, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8140421" target="_blank"〉PubMed〈/a〉

    Cloning of a T cell growth factor that interacts with the beta chain of the interleukin-2 receptor (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-05-13
    Description: A cytokine was identified that stimulated the proliferation of T lymphocytes, and a complementary DNA clone encoding this new T cell growth factor was isolated. The cytokine, designated interleukin-15 (IL-15), is produced by a wide variety of cells and tissues and shares many biological properties with IL-2. Monoclonal antibodies to the beta chain of the IL-2 receptor inhibited the biological activity of IL-15, and IL-15 competed for binding with IL-2, indicating that IL-15 uses components of the IL-2 receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grabstein, K H -- Eisenman, J -- Shanebeck, K -- Rauch, C -- Srinivasan, S -- Fung, V -- Beers, C -- Richardson, J -- Schoenborn, M A -- Ahdieh, M -- New York, N.Y. -- Science. 1994 May 13;264(5161):965-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Immunex Research and Development Corporation, Seattle, WA 98101.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178155" target="_blank"〉PubMed〈/a〉

    Linkage analysis of IL4 and other chromosome 5q31.1 markers and total serum immunoglobulin E concentrations (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-05-20
    Description: Sib-pair analysis of 170 individuals from 11 Amish families revealed evidence for linkage of five markers in chromosome 5q31.1 with a gene controlling total serum immunoglobulin E (IgE) concentration. No linkage was found between these markers and specific IgE antibody concentrations. Analysis of total IgE within a subset of 128 IgE antibody-negative sib pairs confirmed evidence for linkage to 5q31.1, especially to the interleukin-4 gene (IL4). A combination of segregation and maximum likelihood analyses provided further evidence for this linkage. These analyses suggest that IL4 or a nearby gene in 5q31.1 regulates IgE production in a nonantigen-specific (noncognate) fashion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Marsh, D G -- Neely, J D -- Breazeale, D R -- Ghosh, B -- Freidhoff, L R -- Ehrlich-Kautzky, E -- Schou, C -- Krishnaswamy, G -- Beaty, T H -- 1 P41 RR03655/RR/NCRR NIH HHS/ -- AI20059/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 May 20;264(5162):1152-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Johns Hopkins Asthma and Allergy Center, School of Medicine, Baltimore, MD 21224.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178175" target="_blank"〉PubMed〈/a〉

    Gene for familial psoriasis susceptibility mapped to the distal end of human chromosome 17q (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-05-20
    Description: A gene involved in psoriasis susceptibility was localized to the distal region of human chromosome 17q as a result of a genome-wide linkage analysis with polymorphic microsatellites and eight multiply affected psoriasis kindreds. In the family which showed the strongest evidence for linkage, the recombination fraction between a psoriasis susceptibility locus and D17S784 was 0.04 with a maximum two-point lod score of 5.33. There was also evidence for genetic heterogeneity and although none of the linked families showed any association with HLA-Cw6, two unlinked families showed weak levels of association. This study demonstrates that in some families, psoriasis susceptibility is due to variation at a single major genetic locus other than the human lymphocyte antigen locus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tomfohrde, J -- Silverman, A -- Barnes, R -- Fernandez-Vina, M A -- Young, M -- Lory, D -- Morris, L -- Wuepper, K D -- Stastny, P -- Menter, A -- P01-AI2327/AI/NIAID NIH HHS/ -- R01 HL47145/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1994 May 20;264(5162):1141-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, University of Texas Southwestern Medical Center, Dallas 75235-8591.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178173" target="_blank"〉PubMed〈/a〉

    Long-term behavioral recovery in parkinsonian rats by an HSV vector expressing tyrosine hydroxylase (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-25
    Description: One therapeutic approach to treating Parkinson's disease is to convert endogenous striatal cells into levo-3,4-dihydroxyphenylalanine (L-dopa)-producing cells. A defective herpes simplex virus type 1 vector expressing human tyrosine hydroxylase was delivered into the partially denervated striatum of 6-hydroxydopamine-lesioned rats, used as a model of Parkinson's disease. Efficient behavioral and biochemical recovery was maintained for 1 year after gene transfer. Biochemical recovery included increases in both striatal tyrosine hydroxylase enzyme activity and in extracellular dopamine concentrations. Persistence of human tyrosine hydroxylase was revealed by expression of RNA and immunoreactivity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2638002/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2638002/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉During, M J -- Naegele, J R -- O'Malley, K L -- Geller, A I -- EY09749/EY/NEI NIH HHS/ -- NS06208/NS/NINDS NIH HHS/ -- NS28227/NS/NINDS NIH HHS/ -- R01 NS034025/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Nov 25;266(5189):1399-403.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Surgery, Yale University School of Medicine, New Haven, CT 06510.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7669103" target="_blank"〉PubMed〈/a〉

    Efficient neutralization of primary isolates of HIV-1 by a recombinant human monoclonal antibody (1994)

    Details
    Publication Date: 1994-11-11
    Description: The ability of antibodies to neutralize diverse primary isolates of human immunodeficiency virus-type 1 in vitro has been questioned, with implications for the likely efficacy of vaccines. A recombinant human antibody to envelope glycoprotein gp120 was generated and used to show that primary isolates are not refractory to antibody neutralization. The recombinant antibody neutralized more than 75 percent of the primary isolates tested at concentrations that could be achieved by passive immunization, for example, to interrupt maternal-fetal transmission of virus. The broad specificity and efficacy of the antibody implies the conservation of a structural feature on gp120, which could be important in vaccine design.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burton, D R -- Pyati, J -- Koduri, R -- Sharp, S J -- Thornton, G B -- Parren, P W -- Sawyer, L S -- Hendry, R M -- Dunlop, N -- Nara, P L -- AI27742/AI/NIAID NIH HHS/ -- AI33292/AI/NIAID NIH HHS/ -- AI35168/AI/NIAID NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Nov 11;266(5187):1024-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Scripps Research Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973652" target="_blank"〉PubMed〈/a〉

    Noradrenergic regulation of cholinergic differentiation (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-10
    Description: When the sympathetic nerves that innervate rat sweat glands reach their targets, they are induced to switch from using norepinephrine as their neurotransmitter to acetylcholine. Catecholamines (such as norepinephrine) released by nerves growing to the sweat gland induce this phenotypic conversion by stimulating production of a cholinergic differentiation factor [sweat gland factor (SGF)] by gland cells. Here, culture of gland cells with sympathetic, but not sensory, neurons induced SGF production. Blockage of alpha 1- or beta-adrenergic receptors prevented acquisition of the cholinergic phenotype in sympathetic neurons co-cultured with sweat glands, and sweat glands from sympathectomized animals lacked SGF. Thus, reciprocal instructive interactions, mediated in part by small molecule neurotransmitters, direct the development of this synapse.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Habecker, B A -- Landis, S C -- NS-023678/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 10;264(5165):1602-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurosciences, Case Western Reserve University School of Medicine, Cleveland, OH 44106-4975.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8202714" target="_blank"〉PubMed〈/a〉

    The mating of a fly (1994)

    Details
    Publication Date: 1994-06-17
    Description: Courtship in Drosophila is influenced by a wide variety of genes, in that many different kinds of pleiotropic mutations lead to defective courtship. This may seem to be a truism, but the broad temporal and spatial expression of most of the fly's "neuro genes" makes it difficult to exclude elements of such genes' actions as materially underlying reproductive behavior. "Courtship genes" that seem to play more particular roles were originally identified as sensory, learning, or rhythm mutations; their reproductive abnormalities have been especially informative for revealing components of male or female actions that might otherwise have gone unnoticed. Further behavioral mutations seemed originally to be courtship-specific, turned out not to have that property, and have led to a broadened perspective on the nature and action of Drosophila's sex-determination genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hall, J C -- GM-21473/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 17;264(5166):1702-14.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Brandeis University, Waltham, MA 02254-9110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8209251" target="_blank"〉PubMed〈/a〉

    Human severe combined immunodeficiency due to a defect in ZAP-70, a T cell tyrosine kinase (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-06-10
    Description: A homozygous mutation in the kinase domain of ZAP-70, a T cell receptor-associated protein tyrosine kinase, produced a distinctive form of human severe combined immunodeficiency. Manifestations of this disorder included profound immunodeficiency, absence of peripheral CD8+ T cells, and abundant peripheral CD4+ T cells that were refractory to T cell receptor-mediated activation. These findings demonstrate that ZAP-70 is essential for human T cell function and suggest that CD4+ and CD8+ T cells depend on different intracellular signaling pathways to support their development or survival.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Elder, M E -- Lin, D -- Clever, J -- Chan, A C -- Hope, T J -- Weiss, A -- Parslow, T G -- AI29313/AI/NIAID NIH HHS/ -- GM43574/GM/NIGMS NIH HHS/ -- RR01271/RR/NCRR NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1994 Jun 10;264(5165):1596-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, University of California, San Francisco 94143-0110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8202712" target="_blank"〉PubMed〈/a〉

    MHC class I expression in mice lacking the proteasome subunit LMP-7 (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-08-26
    Description: Proteasomes degrade endogenous proteins. Two subunits, LMP-2 and LMP-7, are encoded in a region of the major histocompatibility complex (MHC) that is critical for class I-restricted antigen presentation. Mice with a targeted deletion of the gene encoding LMP-7 have reduced levels of MHC class I cell-surface expression and present the endogenous antigen HY inefficiently; addition of peptides to splenocytes deficient in LMP-7 restores wild-type class I expression levels. This demonstrates the involvement of LMP-7 in the MHC class I presentation pathway and suggests that LMP-7 functions as an integral part of the peptide supply machinery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fehling, H J -- Swat, W -- Laplace, C -- Kuhn, R -- Rajewsky, K -- Muller, U -- von Boehmer, H -- New York, N.Y. -- Science. 1994 Aug 26;265(5176):1234-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Basel Institute for Immunology, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8066463" target="_blank"〉PubMed〈/a〉

    Molecular basis of mammalian sexual determination: activation of Mullerian inhibiting substance gene expression by SRY (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-02
    Description: The pathway of male sexual development in mammals is initiated by SRY, a gene on the short arm of the Y chromosome. Its expression in the differentiating gonadal ridge directs testicular morphogenesis, characterized by elaboration of Mullerian inhibiting substance (MIS) and testosterone. SRY and MIS each belong to conserved gene families that function in the control of growth and differentiation. Structural and biochemical studies of the DNA binding domain of SRY (the HMG box) revealed a protein-DNA interaction consisting of partial side chain intercalation into a widened minor groove. Functional studies of SRY in a cell line from embryonic gonadal ridge demonstrated activation of a gene-regulatory pathway leading to expression of MIS. SRY molecules containing mutations associated with human sex reversal have altered structural interactions with DNA and failed to induce transcription of MIS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haqq, C M -- King, C Y -- Ukiyama, E -- Falsafi, S -- Haqq, T N -- Donahoe, P K -- Weiss, M A -- GM51558/GM/NIGMS NIH HHS/ -- HD30812/HD/NICHD NIH HHS/ -- P30HD28138/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 2;266(5190):1494-500.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Pediatric Surgical Research Laboratory, Massachusetts General Hospital, Boston 02114.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7985018" target="_blank"〉PubMed〈/a〉

    Mutation of a mutL homolog in hereditary colon cancer (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-03-18
    Description: Some cases of hereditary nonpolyposis colorectal cancer (HNPCC) are due to alterations in a mutS-related mismatch repair gene. A search of a large database of expressed sequence tags derived from random complementary DNA clones revealed three additional human mismatch repair genes, all related to the bacterial mutL gene. One of these genes (hMLH1) resides on chromosome 3p21, within 1 centimorgan of markers previously linked to cancer susceptibility in HNPCC kindreds. Mutations of hMLH1 that would disrupt the gene product were identified in such kindreds, demonstrating that this gene is responsible for the disease. These results suggest that defects in any of several mismatch repair genes can cause HNPCC.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Papadopoulos, N -- Nicolaides, N C -- Wei, Y F -- Ruben, S M -- Carter, K C -- Rosen, C A -- Haseltine, W A -- Fleischmann, R D -- Fraser, C M -- Adams, M D -- CA35494/CA/NCI NIH HHS/ -- CA47527/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Mar 18;263(5153):1625-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Johns Hopkins Oncology Center, Baltimore, MD 21231.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8128251" target="_blank"〉PubMed〈/a〉

    Description: In the review by Kristie Macrakis of Beyond the Wall: Memoirs of an East and West German Spy by Werner Stiller, with Jefferson Adams (editor and translator) [Brassey's (US), McLean, VA, 1992; Maxwell Macmillan, London, UK, 1992] (17 Dec., p. 1908), it is stated that physicist Rolf Dobbertin, who denies any spying, was "sent to Paris in 1956 to study at the expense of the Stasi," was "sentenced to 12 years in prison," and "sat in a French jail for five years before he was released in 1991." Legal documents show that Dobbertin, who was arrested in January 1979 for acts of "communication with agents of a foreign power, dealings that could be harmful [intelligence de nature a nuire] to the military or diplomatic situation of France or to its essential economic interest," was jailed until May 1983. He was subsequently tried in 1990 and sentenced to 12 years in prison, but was acquitted of the above charge by a special Assize Court in a second trial in November 1991. According to Dobbertin, he studied continuously at the University of Rostock from 1952 until 1958, and then taught at the University of Berlin for one year before beginning his work in 1959 at the Centre Nationale de la Recherche Scientifigue in France, where he continues to be employed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Treisman, M -- New York, N.Y. -- Science. 1994 May 6;264(5160):760.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8171327" target="_blank"〉PubMed〈/a〉

    Activity-dependent changes in the intrinsic properties of cultured neurons (1994)

    Details
    Publication Date: 1994-05-13
    Description: Learning and memory arise through activity-dependent modifications of neural circuits. Although the activity dependence of synaptic efficacy has been studied extensively, less is known about how activity shapes the intrinsic electrical properties of neurons. Lobster stomatogastric ganglion neurons fire in bursts when receiving synaptic and modulatory input but fire tonically when pharmacologically isolated. Long-term isolation in culture changed their intrinsic activity from tonic firing to burst firing. Rhythmic stimulation reversed this transition through a mechanism that was mediated by a rise in intracellular calcium concentration. These data suggest that neurons regulate their conductances to maintain stable activity patterns and that the intrinsic properties of a neuron depend on its recent history of activation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Turrigiano, G -- Abbott, L F -- Marder, E -- MH46742/MH/NIMH NIH HHS/ -- NS17813/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 May 13;264(5161):974-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Brandeis University, Waltham, MA 02254.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178157" target="_blank"〉PubMed〈/a〉

    Description: Protein tyrosine kinases (PTKs) play an integral role in T cell activation and differentiation. Defects in the Src-family PTKs in mice and in T cell lines have resulted in variable defects in thymic development and in T cell antigen receptor (TCR) signal transduction. Here, three siblings are described with an autosomal recessive form of severe combined immunodeficiency disease (SCID) in which ZAP-70, a non-Src PTK, is absent as a result of mutations in the ZAP-70 gene. This absence is associated with defects in TCR signal transduction, suggesting an important functional role for ZAP-70.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chan, A C -- Kadlecek, T A -- Elder, M E -- Filipovich, A H -- Kuo, W L -- Iwashima, M -- Parslow, T G -- Weiss, A -- AR-20684/AR/NIAMS NIH HHS/ -- GM39553/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 10;264(5165):1599-601.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Medicine, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8202713" target="_blank"〉PubMed〈/a〉

    Publication Date: 1994-11-18
    Description: In April and May 1979, an unusual anthrax epidemic occurred in Sverdlovsk, Union of Soviet Socialist Republics. Soviet officials attributed it to consumption of contaminated meat. U.S. agencies attributed it to inhalation of spores accidentally released at a military microbiology facility in the city. Epidemiological data show that most victims worked or lived in a narrow zone extending from the military facility to the southern city limit. Farther south, livestock died of anthrax along the zone's extended axis. The zone paralleled the northerly wind that prevailed shortly before the outbreak. It is concluded that the escape of an aerosol of anthrax pathogen at the military facility caused the outbreak.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meselson, M -- Guillemin, J -- Hugh-Jones, M -- Langmuir, A -- Popova, I -- Shelokov, A -- Yampolskaya, O -- New York, N.Y. -- Science. 1994 Nov 18;266(5188):1202-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Biology, Harvard University, Cambridge, MA 02138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973702" target="_blank"〉PubMed〈/a〉

    Description: The association between quantitative genetic variation in bristle number and molecular variation at a candidate neurogenic locus, scabrous, was examined in Drosophila melanogaster. Approximately 32 percent of the genetic variation in abdominal bristle number (21 percent for sternopleural bristle number) among 47 second chromosomes from a natural population was correlated with DNA sequence polymorphisms at this locus. Several polymorphic sites associated with large phenotypic effects occurred at intermediate frequency. Quantitative genetic variation in natural populations caused by alleles that have large effects at a few loci and that segregate at intermediate frequencies conflicts with the classical infinitesimal model of the genetic basis of quantitative variation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lai, C -- Lyman, R F -- Long, A D -- Langley, C H -- Mackay, T F -- GM45146/GM/NIGMS NIH HHS/ -- GM45344/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 9;266(5191):1697-702.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Population Biology, University of California at Davis 95616.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7992053" target="_blank"〉PubMed〈/a〉

    Adenosine inhibition of mesopontine cholinergic neurons: implications for EEG arousal (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-02-04
    Description: Increased discharge activity of mesopontine cholinergic neurons participates in the production of electroencephalographic (EEG) arousal; such arousal diminishes as a function of the duration of prior wakefulness or of brain hyperthermia. Whole-cell and extracellular recordings in a brainstem slice show that mesopontine cholinergic neurons are under the tonic inhibitory control of endogenous adenosine, a neuromodulator released during brain metabolism. This inhibitory tone is mediated postsynaptically by an inwardly rectifying potassium conductance and by an inhibition of the hyperpolarization-activated current. These data provide a coupling mechanism linking neuronal control of EEG arousal with the effects of prior wakefulness, brain hyperthermia, and the use of the adenosine receptor blockers caffeine and theophylline.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3612520/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3612520/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rainnie, D G -- Grunze, H C -- McCarley, R W -- Greene, R W -- R01 MH039683/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1994 Feb 4;263(5147):689-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, Harvard University, Brockton, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303279" target="_blank"〉PubMed〈/a〉

    Reactivation of hippocampal ensemble memories during sleep (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-07-29
    Description: Simultaneous recordings were made from large ensembles of hippocampal "place cells" in three rats during spatial behavioral tasks and in slow-wave sleep preceding and following these behaviors. Cells that fired together when the animal occupied particular locations in the environment exhibited an increased tendency to fire together during subsequent sleep, in comparison to sleep episodes preceding the behavioral tasks. Cells that were inactive during behavior, or that were active but had non-overlapping spatial firing, did not show this increase. This effect, which declined gradually during each post-behavior sleep session, may result from synaptic modification during waking experience. Information acquired during active behavior is thus re-expressed in hippocampal circuits during sleep, as postulated by some theories of memory consolidation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, M A -- McNaughton, B L -- MH46823/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1994 Jul 29;265(5172):676-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neural Systems, Memory, and Aging, University of Arizona, Tucson 85724.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8036517" target="_blank"〉PubMed〈/a〉

    Natural vertical transmission of western equine encephalomyelitis virus in mosquitoes (1994)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 1994-02-04
    Description: The mechanism by which western equine encephalomyelitis (WEE) virus and other mosquito-borne alphaviruses (Togaviridae) survive during periods of vector inactivity is unknown. Recently, three strains of WEE virus were isolated from adult Aedes dorsalis collected as larvae from a salt marsh in a coastal region of California. This provides evidence of vertical transmission of WEE virus in mosquitoes in nature. Vertical transmission in Ae. dorsalis and closely related mosquito species may be an important mechanism for the maintenance of WEE virus in temperate regions in North America where horizontal transmission of the virus is seasonal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fulhorst, C F -- Hardy, J L -- Eldridge, B F -- Presser, S B -- Reeves, W C -- AI-03028/AI/NIAID NIH HHS/ -- AI-26154/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1994 Feb 4;263(5147):676-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Public Health, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303276" target="_blank"〉PubMed〈/a〉

    Description: The effect of the number of cystic fibrosis (CF) alleles on cholera toxin (CT)-induced intestinal secretion was examined in the CF mouse model. CF mice that expressed no CF transmembrane conductance regulator (CFTR) protein did not secrete fluid in response to CT. Heterozygotes expressed 50 percent of the normal amount of CFTR protein in the intestinal epithelium and secreted 50 percent of the normal fluid and chloride ion in intestinal epithelium and secreted 50 percent of the normal fluid and chloride ion and fluid secretion suggests that CF heterozygotes might possess a selective advantage of resistance to cholera.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gabriel, S E -- Brigman, K N -- Koller, B H -- Boucher, R C -- Stutts, M J -- DK46003/DK/NIDDK NIH HHS/ -- HL34322/HL/NHLBI NIH HHS/ -- HL42384/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1994 Oct 7;266(5182):107-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of North Carolina, Chapel Hill 27599.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7524148" target="_blank"〉PubMed〈/a〉

    Publication Date: 1994-02-11
    Description: Interleukin-1 beta converting enzyme (ICE) is a mammalian homolog of CED-3, a protein required for programmed cell death in the nematode Caenorhabditis elegans. The activity of ICE can be specifically inhibited by the product of crmA, a cytokine response modifier gene encoded by cowpox virus. Microinjection of the crmA gene into chicken dorsal root ganglion neurons was found to prevent cell death induced by deprivation of nerve growth factor. Thus, ICE is likely to participate in neuronal death in vertebrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gagliardini, V -- Fernandez, P A -- Lee, R K -- Drexler, H C -- Rotello, R J -- Fishman, M C -- Yuan, J -- New York, N.Y. -- Science. 1994 Feb 11;263(5148):826-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cardiovascular Research Center, Massachusetts General Hospital, Charlestown 02129.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303301" target="_blank"〉PubMed〈/a〉

    Description: Most human peripheral blood gamma delta T lymphocytes respond to hitherto unidentified mycobacterial antigens. Four ligands from Mycobacterium tuberculosis strain H37Rv that stimulated proliferation of a major human gamma delta T cell subset were isolated and partially characterized. One of these ligands, TUBag4, is a 5' triphosphorylated thymidine-containing compound, to which the three other stimulatory molecules are structurally related. These findings support the hypothesis that some gamma delta T cells recognize nonpeptidic ligands.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Constant, P -- Davodeau, F -- Peyrat, M A -- Poquet, Y -- Puzo, G -- Bonneville, M -- Fournie, J J -- New York, N.Y. -- Science. 1994 Apr 8;264(5156):267-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department III, Laboratoire de Pharmacologie et de Toxicologie Fondamentales du CNRS, Toulouse, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8146660" target="_blank"〉PubMed〈/a〉

    Publication Date: 1994-03-11
    Description: The repair of cyclobutane pyrimidine dimers (CPDs), DNA lesions induced by ultraviolet light, was studied at nucleotide resolution. Human fibroblasts were irradiated with ultraviolet light and allowed to repair. The DNA was enzymatically cleaved at the CPDs, and the induced breaks along the promoter and exon 1 of the PGK1 gene were mapped by ligation-mediated polymerase chain reaction. Repair rates within the nontranscribed strand varied as much as 15-fold, depending on nucleotide position. Preferential repair of the transcribed strand began just downstream of the transcription start site but was most pronounced beginning at nucleotide +140 in exon 1. The promoter contained two slowly repaired regions that coincided with two transcription factor binding sites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gao, S -- Drouin, R -- Holmquist, G P -- CA54773/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1994 Mar 11;263(5152):1438-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Beckman Research Institute of the City of Hope, Department of Biology, Duarte, CA 91010.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8128226" target="_blank"〉PubMed〈/a〉

    A subset of CD4+ thymocytes selected by MHC class I molecules (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-03-25
    Description: To complete their maturation, most immature thymocytes depend on the simultaneous engagement of their antigen receptor [alpha beta T cell receptor (TCR)] and their CD4 or CD8 coreceptors with major histocompatibility complex class II or I ligands, respectively. However, a normal subset of mature alpha beta TCR+ thymocytes did not follow these rules. These thymocytes expressed NK1.1 and a restricted set of alpha beta TCRs that are intrinsically class I-reactive because their positive selection was class I-dependent but CD8-independent. These cells were CD4+ and CD4-8- but never CD8+, because the presence of CD8 caused negative selection. Thus, neither CD4 nor CD8 contributes signals that direct their maturation into the CD4+ and CD4-8- lineages.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bendelac, A -- Killeen, N -- Littman, D R -- Schwartz, R H -- New York, N.Y. -- Science. 1994 Mar 25;263(5154):1774-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cellular and Molecular Immunology, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7907820" target="_blank"〉PubMed〈/a〉

    Kin selection, social structure, gene flow, and the evolution of chimpanzees (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-08-26
    Description: Hypotheses about chimpanzee social behavior, phylogeography, and evolution were evaluated by noninvasive genotyping of free-ranging individuals from 20 African sites. Degrees of relatedness among individuals in one community were inferred from allele-sharing at eight nuclear simple sequence repeat (SSR) loci. Males are related on the order of half-siblings, and homozygosity is significantly increased at several SSR loci compared to Hardy-Weinberg expectations. These data support the kin-selection hypothesis for the evolution of cooperation among males. Sequence variation patterns at two mitochondrial loci indicate historically high long-distance gene flow and clarify the relationships among three allopatric subspecies. The unexpectedly large genetic distance between the western subspecies, Pan troglodytes verus, and the other two subspecies suggests a divergence time of about 1.58 million years. This result, if confirmed at nuclear loci and supported by eco-behavioral data, implies that P. t. verus should be elevated to full species rank.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morin, P A -- Moore, J J -- Chakraborty, R -- Jin, L -- Goodall, J -- Woodruff, D S -- 1T32 HG00005-02/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 1994 Aug 26;265(5176):1193-201.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of California, San Diego, La Jolla 92093-0116.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7915048" target="_blank"〉PubMed〈/a〉

    Description: Encounters with antigen can stimulate T cells to become activated and proliferate, become nonresponsive to antigen, or to die. T cell death was shown to be a physiological response to interleukin-2-stimulated cell cycling and T cell receptor reengagement at high antigen doses. This feedback regulatory mechanism attenuates the immune response by deleting a portion of newly dividing, antigen-reactive T cells. This mechanism deleted autoreactive T cells and abrogated the clinical and pathological signs of autoimmune encephalomyelitis in mice after repetitive administration of myelin basic protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Critchfield, J M -- Racke, M K -- Zuniga-Pflucker, J C -- Cannella, B -- Raine, C S -- Goverman, J -- Lenardo, M J -- New York, N.Y. -- Science. 1994 Feb 25;263(5150):1139-43.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunology, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7509084" target="_blank"〉PubMed〈/a〉

    Requirement for BDNF in activity-dependent survival of cortical neurons (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-03-18
    Description: Cultured embryonic cortical neurons from rats were used to explore mechanisms of activity-dependent neuronal survival. Cell survival was increased by the activation of voltage-sensitive calcium channels (VSCCs) but not by activation of N-methyl-D-aspartate receptors. These effects correlated with the expression of brain-derived neurotrophic factor (BDNF) induced by these two classes of calcium channels. Antibodies to BDNF (which block intracellular signaling by BDNF, but not by nerve growth factor, NT3, or NT4/5) reduced the survival of cortical neurons and reversed the VSCC-mediated increase in survival. Thus, endogenous BDNF is a trophic factor for cortical neurons whose expression is VSCC-regulated and that functions in the VSCC-dependent survival of these neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ghosh, A -- Carnahan, J -- Greenberg, M E -- NS28829/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 Mar 18;263(5153):1618-23.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Molecular Genetics, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7907431" target="_blank"〉PubMed〈/a〉

    An experimental study of inbreeding depression in a natural habitat (1994)

    Details

    Description: Inbreeding is known to lead to decreased survival and reproduction in captive populations of animals. It is also important to know whether inbreeding has deleterious effects in natural habitats. An estimate was made of the effects of inbreeding in white-footed mice, Peromyscus leucopus noveboracensis, derived from a wild population. This study demonstrates that inbreeding had a significant detrimental effect on the survivorship of mice reintroduced into a natural habitat. This effect was more severe than the effect observed in laboratory studies of the population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jimenez, J A -- Hughes, K A -- Alaks, G -- Graham, L -- Lacy, R C -- New York, N.Y. -- Science. 1994 Oct 14;266(5183):271-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, University of Illinois-Chicago 60680.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7939661" target="_blank"〉PubMed〈/a〉

    The return of Phineas Gage: clues about the brain from the skull of a famous patient (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-05-20
    Description: When the landmark patient Phineas Gage died in 1861, no autopsy was performed, but his skull was later recovered. The brain lesion that caused the profound personality changes for which his case became famous has been presumed to have involved the left frontal region, but questions have been raised about the involvement of other regions and about the exact placement of the lesion within the vast frontal territory. Measurements from Gage's skull and modern neuroimaging techniques were used to reconstitute the accident and determine the probable location of the lesion. The damage involved both left and right prefrontal cortices in a pattern that, as confirmed by Gage's modern counterparts, causes a defect in rational decision making and the processing of emotion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Damasio, H -- Grabowski, T -- Frank, R -- Galaburda, A M -- Damasio, A R -- P01 NS19632/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1994 May 20;264(5162):1102-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, University of Iowa Hospitals & Clinics, Iowa City 52242.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8178168" target="_blank"〉PubMed〈/a〉
