    Notes: Summary Serum chemistry and bone morphometry of the proximal tibial metaphysis were performed in 3-month-old double fluorescent-labeled, female Sprague-Dawley rats subjected to bilateral ovariectomy or sham surgery for 4 months prior to treatment with 0, 0.3, 1, 3, or 6 mg of prostaglandin E2 (PGE2)/kg/day subcutaneously for 30 days. The 4-month postovariectomized rats possessed an osteopenic proximal tibial metaphysis with 7% trabecular area compared with controls (19%). PGE2 treatment elevated osteocalcin levels and augmented proximal tibial metaphyseal bone area in ovariectomized and sham-operated rats. Osteopenic, ovariectomized rats treated with 6 mg PGE2/kg/day for 30 days restored bone area to levels of agematched sham-operated rats. Morphometric analyses showed increased woven and lamellar bone area, fluorescent-labeled perimeter (osteoblastic recruitment), mineral apposition rate (osteoblastic activity), bone formation rate (BFR/BV), and longitudinal bone growth. These dramatic bone changes were all significantly increased at the doseresponse manner. This study showed that in vivo PGE2 is a powerful activator of bone remodeling, it increases both bone resorption and bone formation, and produces an anabolic effect by shifting bone balance to the positive direction. Furthermore, PGE2-induced augmentation of metaphyseal bone area in ovariectomized rats was at least two times greater than in sham-operated rats.

    High probability opening of NMDA receptor channels by L-glutamate (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-01-24
    Description: Synaptic plasticity can be triggered by calcium flux into neurons through synaptically activated N-methyl-D-aspartate (NMDA) receptor channels. The amplitude and time course of the resulting intracellular calcium transient depend on the number of open NMDA receptor channels and the kinetics of their activation. Short applications of L-glutamate to outside-out patches from hippocampal neurons in the presence and absence of MK-801 revealed that about 30 percent of L-glutamate-bound channels are open at the peak of the current. This high probability of opening suggests that very few channels are required to guarantee a large, localized postsynaptic calcium transient.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jahr, C E -- NS21419/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1992 Jan 24;255(5043):470-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vollum Institute L474, Oregon Health Sciences University, Portland 97201.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1346477" target="_blank"〉PubMed〈/a〉

    Molecular epidemiology of HIV transmission in a dental practice (1992)

    Details
    Publication Date: 1992-05-22
    Description: Human immunodeficiency virus type 1 (HIV-1) transmission from infected patients to health-care workers has been well documented, but transmission from an infected health-care worker to a patient has not been reported. After identification of an acquired immunodeficiency syndrome (AIDS) patient who had no known risk factors for HIV infection but who had undergone an invasive procedure performed by a dentist with AIDS, six other patients of this dentist were found to be HIV-infected. Molecular biologic studies were conducted to complement the epidemiologic investigation. Portions of the HIV proviral envelope gene from each of the seven patients, the dentist, and 35 HIV-infected persons from the local geographic area were amplified by polymerase chain reaction and sequenced. Three separate comparative genetic analyses--genetic distance measurements, phylogenetic tree analysis, and amino acid signature pattern analysis--showed that the viruses from the dentist and five dental patients were closely related. These data, together with the epidemiologic investigation, indicated that these patients became infected with HIV while receiving care from a dentist with AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ou, C Y -- Ciesielski, C A -- Myers, G -- Bandea, C I -- Luo, C C -- Korber, B T -- Mullins, J I -- Schochetman, G -- Berkelman, R L -- Economou, A N -- New York, N.Y. -- Science. 1992 May 22;256(5060):1165-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of HIV/AIDS, Centers for Disease Control, Atlanta, GA 30333.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1589796" target="_blank"〉PubMed〈/a〉

    Syntaxin: a synaptic protein implicated in docking of synaptic vesicles at presynaptic active zones (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-07-10
    Description: Synaptic vesicles store neurotransmitters that are released during calcium-regulated exocytosis. The specificity of neurotransmitter release requires the localization of both synaptic vesicles and calcium channels to the presynaptic active zone. Two 35-kilodalton proteins (p35 or syntaxins) were identified that interact with the synaptic vesicle protein p65 (synaptotagmin). The p35 proteins are expressed only in the nervous system, are 84 percent identical, include carboxyl-terminal membrane anchors, and are concentrated on the plasma membrane at synaptic sites. An antibody to p35 immunoprecipitated solubilized N-type calcium channels. The p35 proteins may function in docking synaptic vesicles near calcium channels at presynaptic active zones.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bennett, M K -- Calakos, N -- Scheller, R H -- 2T32G07365/PHS HHS/ -- New York, N.Y. -- Science. 1992 Jul 10;257(5067):255-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular and Cellular Physiology, Stanford University Medical Center, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1321498" target="_blank"〉PubMed〈/a〉

    Requirement for the adenovirus type 9 E4 region in production of mammary tumors (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-09-07
    Description: Oncogenic viruses demonstrating a strict tropism for the mammary gland provide special opportunities to study the susceptibility of this tissue to neoplasia. In rats, human adenovirus type 9 (Ad9) elicits mammary fibroadenomas that are similar to common breast tumors in women, as well as phyllodes-like tumors and mammary sarcomas. By constructing recombinant adenoviruses between Ad9 and Ad26 (a related nontumorigenic virus), it was shown that the Ad9 E4 region was absolutely required to produce these mammary tumors. This indicates that an adenovirus gene located outside the classic transforming region (E1) can significantly influence the in vivo oncogenicity of an adenovirus. Consistent with a direct role in mammary gland oncogenesis, the Ad9 E4 region also exhibited transforming properties in vitro. Therefore, the Ad9 E4 region is a viral oncogene specifically involved in mammary gland tumorigenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Javier, R -- Raska, K Jr -- Shenk, T -- CA 21196/CA/NCI NIH HHS/ -- CA 41086/CA/NCI NIH HHS/ -- T32 CA09528/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1992 Aug 28;257(5074):1267-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular Biology, Princeton University, NJ 08544.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1519063" target="_blank"〉PubMed〈/a〉

    Identification of ras oncogene mutations in the stool of patients with curable colorectal tumors (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-04-03
    Description: Colorectal (CR) tumors are usually curable if detected before metastasis. Because genetic alterations are associated with the development of these tumors, mutant genes may be found in the stool of individuals with CR neoplasms. The stools of nine patients whose tumors contained mutations of K-ras were analyzed. In eight of the nine cases, the ras mutations were detectable in DNA purified from the stool. These patients included those with benign and malignant neoplasms from proximal and distal colonic epithelium. Thus, colorectal tumors can be detected by a noninvasive method based on the molecular pathogenesis of the disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sidransky, D -- Tokino, T -- Hamilton, S R -- Kinzler, K W -- Levin, B -- Frost, P -- Vogelstein, B -- CA06973/CA/NCI NIH HHS/ -- CA35494/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1992 Apr 3;256(5053):102-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Oncology, Johns Hopkins University, Baltimore, MD 21231.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1566048" target="_blank"〉PubMed〈/a〉

    Repression of the insulin-like growth factor II gene by the Wilms tumor suppressor WT1 (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-07-31
    Description: The Wilms tumor suppressor gene wt1 encodes a zinc finger DNA binding protein, WT1, that functions as a transcriptional repressor. The fetal mitogen insulin-like growth factor II (IGF-II) is overexpressed in Wilms tumors and may have autocrine effects in tumor progression. The major fetal IGF-II promoter was defined in transient transfection assays as a region spanning from nucleotides -295 to +135, relative to the transcription start site. WT1 bound to multiple sites in this region and functioned as a potent repressor of IGF-II transcription in vivo. Maximal repression was dependent on the presence of WT1 binding sites on each side of the transcriptional initiation site. These findings provide a molecular basis for overexpression of IGF-II in Wilms tumors and suggest that WT1 negatively regulates blastemal cell proliferation by limiting the production of a fetal growth factor in the developing vertebrate kidney.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drummond, I A -- Madden, S L -- Rohwer-Nutter, P -- Bell, G I -- Sukhatme, V P -- Rauscher, F J 3rd -- CA 10817/CA/NCI NIH HHS/ -- CA 47983/CA/NCI NIH HHS/ -- CA 52009/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1992 Jul 31;257(5070):674-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1323141" target="_blank"〉PubMed〈/a〉

    Description: This article provides a historical perspective for the patenting of gene sequences and describes the fundamentals and evolution of patent law. It summarizes federal technology transfer law and policy and assesses the impacts of patenting on academic research. The patentability of gene sequences is then considered along with potential impacts that published sequence data may have on obtaining patent protection for downstream products. Industry's position on gene patenting is summarized and perspectives from the emerging public record on these issues are presented. The article discussing points at which the filing of patent applications and the licensing of patents may be appropriate. It concludes that technology transfer policies for genome research must be adopted carefully so that they remain viable in a time of rapid technological change.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adler, R G -- New York, N.Y. -- Science. 1992 Aug 14;257(5072):908-14.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1502557" target="_blank"〉PubMed〈/a〉

    Cholecystokinin antianalgesia: safety cues abolish morphine analgesia (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-05-08
    Description: Environmental stimuli that signal the occurrence of aversive or dangerous events activate endogenous opiate analgesia systems. Signals for safety (the nonoccurrence of aversive events) produce the opposite and inhibit environmentally produced analgesia. Stimuli that signal safety are now shown to abolish the analgesic effect of morphine, even when morphine is applied directly to spinal cord. Further, this antiopiate effect occurs because the environmental stimulus leads to release of the neuropeptide cholecystokinin in the spinal cord. This process may contribute to the regulation of pain and the development of opiate tolerance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wiertelak, E P -- Maier, S F -- Watkins, L R -- 5T32MH14617-15/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1992 May 8;256(5058):830-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of Colorado, Boulder 80309.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1589765" target="_blank"〉PubMed〈/a〉

In the developing mammalian retina, gradual regression of chondroitin sulfate may help control the onset of ganglion cell differentiation and initial direction of their axons.

    Publication Date: 1992-08-14
    Description: In the past year, the National Institutes of Health (NIH) has filed patent applications on more than 2750 partial complementary DNA sequences of unknown function. The rationale for the filings--that patent protection may be necessary to ensure that private firms are willing to invest in developing related products--rests on two premises: first, that NIH may obtain patent rights that will offer effective product monopolies to licensee firms, and second, that unless NIH obtains these rights now, firms will be unable to obtain a comparable degree of exclusivity by other means, such as by obtaining patents on their own subsequent innovations. Neither premise is clearly wrong, although both are subject to doubt in view of statements from industry representatives that the NIH patenting strategy will deter rather than promote product development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eisenberg, R S -- New York, N.Y. -- Science. 1992 Aug 14;257(5072):903-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of Michigan Law School, Ann Arbor 48109.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1502556" target="_blank"〉PubMed〈/a〉

    Lyme disease in California: a novel enzootic transmission cycle of Borrelia burgdorferi (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-06-05
    Description: Knowledge of zoonotic transmission cycles is essential for the development of effective strategies for disease prevention. The enzootiology of Lyme disease in California differs fundamentally from that reported from the eastern United States. Woodrats, not mice, serve as reservoir hosts, and Ixodes neotomae, a nonhuman-biting tick, maintains the agent of Lyme disease, Borrelia burgdorferi, in enzootic cycles.

    Activity-dependent decrease in NMDA receptor responses during development of the visual cortex (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-11-06
    Description: Plasticity of the developing visual system has been regarded as the best model for changes of neuronal connections under the influence of the environment. N-methyl-D-aspartate (NMDA) receptors are crucial for experience-dependent synaptic modifications that occur in the developing visual cortex. NMDA-mediated excitatory postsynaptic currents (EPSCs) in layer IV neurons of the visual cortex lasted longer in young rats than in adult rats, and the duration of the EPSCs became progressively shorter, in parallel with the developmental reduction in synaptic plasticity. This decrease in NMDA receptor-mediated EPSC duration is delayed when the animals are reared in the dark, a condition that prolongs developmental plasticity, and is prevented by treatment with tetrodotoxin, a procedure that inhibits neural activity. Application of L-glutamate to outside-out patches excised from layer IV neurons of young, but not of adult, rats activated prolonged bursts of NMDA channel openings. A modification of the NMDA receptor gating properties may therefore account for the age-dependent decline of visual cortical plasticity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carmignoto, G -- Vicini, S -- P01 NS 28130-01/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1992 Nov 6;258(5084):1007-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉FIDIA Georgetown Institute for the Neurosciences, Georgetown University School of Medicine, Washington, DC 20007.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1279803" target="_blank"〉PubMed〈/a〉

    Interleukin-8 as a macrophage-derived mediator of angiogenesis (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-12-11
    Description: Angiogenic factors produced by monocytes-macrophages are involved in the pathogenesis of chronic inflammatory disorders characterized by persistent angiogenesis. The possibility was tested that interleukin-8 (IL-8), which is a cytokine that is chemotactic for lymphocytes and neutrophils, is also angiogenic. Human recombinant IL-8 was potently angiogenic when implanted in the rat cornea and induced proliferation and chemotaxis of human umbilical vein endothelial cells. Angiogenic activity present in the conditioned media of inflamed human rheumatoid synovial tissue macrophages or lipopolysaccharide-stimulated blood monocytes was equally blocked by antibodies to either IL-8 or tumor necrosis factor-alpha. An IL-8 antisense oligonucleotide specifically blocked the production of monocyte-induced angiogenic activity. These data suggest a function for macrophage-derived IL-8 in angiogenesis-dependent disorders such as rheumatoid arthritis, tumor growth, and wound repair.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koch, A E -- Polverini, P J -- Kunkel, S L -- Harlow, L A -- DiPietro, L A -- Elner, V M -- Elner, S G -- Strieter, R M -- AR30692/AR/NIAMS NIH HHS/ -- AR41492/AR/NIAMS NIH HHS/ -- HL39926/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1992 Dec 11;258(5089):1798-801.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Northwestern University Medical School, Chicago, IL 60611.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1281554" target="_blank"〉PubMed〈/a〉

    Publication Date: 1992-05-18
    Description: Triplet repeats are the sites of mutation in three human heritable disorders, spinal and bulbar muscular atrophy (SBMA), fragile X syndrome, and myotonic dystrophy (DM). These repeats are GC-rich and highly polymorphic in the normal population. Fragile X syndrome and DM are examples of diseases in which premutation alleles cause little or no disease in the individual, but give rise to significantly amplified repeats in affected progeny. This newly identified mechanism of mutation has, so far, been identified in two of the most common heritable disorders, fragile X syndrome and DM, and one rare disease, SBMA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Caskey, C T -- Pizzuti, A -- Fu, Y H -- Fenwick, R G Jr -- Nelson, D L -- 1R01HD29256/HD/NICHD NIH HHS/ -- P30-HG00210/HG/NHGRI NIH HHS/ -- P30HD24064/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1992 May 8;256(5058):784-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Molecular Genetics, Baylor College of Medicine, Houston, TX 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1589758" target="_blank"〉PubMed〈/a〉

    Sexually antagonistic genes: experimental evidence (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-06-05
    Description: When selection differs between the sexes, a mutation beneficial to one sex may be harmful to the other (sexually antagonistic). Because the sexes share a common gene pool, selection in one sex can interfere with the other's adaptive evolution. Theory predicts that sexually antagonistic mutations should accumulate in tight linkage with a new sex-determining gene, even when the harm to benefit ratio is high. Genetic markers and artificial selection were used to make a pair of autosomal genes segregate like a new pair of sex-determining genes in a Drosophila melanogaster model system. A 29-generation study provides experimental evidence that sexually antagonistic genes may be common in nature and will accumulate in response to a new sex-determining gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rice, W R -- New York, N.Y. -- Science. 1992 Jun 5;256(5062):1436-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biology Board of Studies, University of California, Santa Cruz 95064.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1604317" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1992-10-23
    Description: Hemodynamic shear stress affects endothelial cell structure and function, but little is known about the signal transduction mechanisms involved in these processes. The effect of laminar shear stress on cytosolic pH (pHi) was examined in rat aortic endothelial cells cultured in glass capillary tubes. Shear stress forces led to a rapid decrease in pHi (maximal effect 0.09 pH unit at 13.4 dynes per square centimeter). Removal of specific ions or addition of exchange inhibitors suggests that in vascular endothelial cells shear stress forces activate both an alkali extruder, sodium ion-independent chloride-bicarbonate ion exchange, and an acid extruder, sodium-hydrogen ion exchange; the net effect in physiologic buffer with the bicarbonate ion is a decrease in pHi.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ziegelstein, R C -- Cheng, L -- Capogrossi, M C -- New York, N.Y. -- Science. 1992 Oct 23;258(5082):656-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cardiovascular Science, National Institute on Aging, National Institutes of Health, Baltimore, MD 21224.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1329207" target="_blank"〉PubMed〈/a〉

    The time course of glutamate in the synaptic cleft (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-11-27
    Description: The peak concentration and rate of clearance of neurotransmitter from the synaptic cleft are important determinants of synaptic function, yet the neurotransmitter concentration time course is unknown at synapses in the brain. The time course of free glutamate in the cleft was estimated by kinetic analysis of the displacement of a rapidly dissociating competitive antagonist from N-methyl-D-aspartate (NMDA) receptors during synaptic transmission. Glutamate peaked at 1.1 millimolar and decayed with a time constant of 1.2 milliseconds at cultured hippocampal synapses. This time course implies that transmitter saturates postsynaptic NMDA receptors. However, glutamate dissociates much more rapidly from alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors. Thus, the time course of free glutamate predicts that dissociation contributes to the decay of the AMPA receptor-mediated postsynaptic current.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clements, J D -- Lester, R A -- Tong, G -- Jahr, C E -- Westbrook, G L -- MH46613/MH/NIMH NIH HHS/ -- NS21419/NS/NINDS NIH HHS/ -- NS26494/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1992 Nov 27;258(5087):1498-501.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vollum Institute, Oregon Health Sciences University, Portland 97201.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1359647" target="_blank"〉PubMed〈/a〉

    Antisense and antigene properties of peptide nucleic acids (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-11-27
    Description: Peptide nucleic acids (PNAs) are polyamide oligomers that can strand invade duplex DNA, causing displacement of one DNA strand and formation of a D-loop. Binding of either a T10 PNA or a mixed sequence 15-mer PNA to the transcribed strand of a G-free transcription cassette caused 90 to 100 percent site-specific termination of pol II transcription elongation. When a T10 PNA was bound on the nontranscribed strand, site-specific inhibition never exceeded 50 percent. Binding of PNAs to RNA resulted in site-specific termination of both reverse transcription and in vitro translation, precisely at the position of the PNA.RNA heteroduplex. Nuclear microinjection of cells constitutively expressing SV40 large T antigen (T Ag) with either a 15-mer or 20-mer PNA targeted to the T Ag messenger RNA suppressed T Ag expression. This effect was specific in that there was no reduction in beta-galactosidase expression from a coinjected expression vector and no inhibition of T Ag expression after microinjection of a 10-mer PNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hanvey, J C -- Peffer, N J -- Bisi, J E -- Thomson, S A -- Cadilla, R -- Josey, J A -- Ricca, D J -- Hassman, C F -- Bonham, M A -- Au, K G -- New York, N.Y. -- Science. 1992 Nov 27;258(5087):1481-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Glaxo Inc.

    Reversal of diabetes insipidus in Brattleboro rats: intrahypothalamic injection of vasopressin mRNA (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-02-21
    Description: Messenger RNAs occur within the axons of magnocellular hypothalamic neurons known to secrete oxytocin and vasopressin. In Brattleboro rats, which have a genetic mutation that renders them incapable of vasopressin expression and secretion and thus causes diabetes insipidus, injection into the hypothalamus of purified mRNAs from normal rat hypothalami or of synthetic copies of the vasopressin mRNA leads to selective uptake, retrograde transport, and expression of vasopressin exclusively in the magnocellular neurons. Temporary reversal of their diabetes insipidus (for up to 5 days) can be observed within hours of the injection. Intra-axonal mRNAs may represent an additional category of chemical signals for neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jirikowski, G F -- Sanna, P P -- Maciejewski-Lenoir, D -- Bloom, F E -- MH 47680/MH/NIMH NIH HHS/ -- NS 22347-03/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1992 Feb 21;255(5047):996-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuropharmacology, Scripps Research Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1546298" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1992-10-02
    Description: A unified genetic, physical, and functional map of the human X chromosome is being built through a concerted, international effort. About 40 percent of the 160 million base pairs of the X chromosome DNA have been cloned in overlapping, ordered contigs derived from yeast artificial chromosomes. This rapid progress toward a physical map is accelerating the identification of inherited disease genes, 26 of which are already cloned and more than 50 others regionally localized by linkage analysis. This article summarizes the mapping strategies now used and the impact of genome research on the understanding of X chromosome inactivation and X-linked diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mandel, J L -- Monaco, A P -- Nelson, D L -- Schlessinger, D -- Willard, H -- New York, N.Y. -- Science. 1992 Oct 2;258(5079):103-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de Genetique Moleculaire des Eucaryotes du CNRS, INSERM, Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1439756" target="_blank"〉PubMed〈/a〉

    Comparative genomic hybridization for molecular cytogenetic analysis of solid tumors (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-10-30
    Description: Comparative genomic hybridization produces a map of DNA sequence copy number as a function of chromosomal location throughout the entire genome. Differentially labeled test DNA and normal reference DNA are hybridized simultaneously to normal chromosome spreads. The hybridization is detected with two different fluorochromes. Regions of gain or loss of DNA sequences, such as deletions, duplications, or amplifications, are seen as changes in the ratio of the intensities of the two fluorochromes along the target chromosomes. Analysis of tumor cell lines and primary bladder tumors identified 16 different regions of amplification, many in loci not previously known to be amplified.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kallioniemi, A -- Kallioniemi, O P -- Sudar, D -- Rutovitz, D -- Gray, J W -- Waldman, F -- Pinkel, D -- CA 44768/CA/NCI NIH HHS/ -- CA 45919/CA/NCI NIH HHS/ -- CA 47537/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1992 Oct 30;258(5083):818-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Laboratory Medicine, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1359641" target="_blank"〉PubMed〈/a〉

    Balancing selection at allozyme loci in oysters: implications from nuclear RFLPs (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-04-03
    Description: Population genetic analyses that depend on the assumption of neutrality for allozyme markers are used widely. Restriction fragment length polymorphisms in nuclear DNA of the American oyster evidence a pronounced population subdivision concordant with mitochondrial DNA. This finding contrasts with a geographic uniformity in allozyme frequencies previously thought to reflect high gene flow mediated by the pelagic gametes and larvae. The discordance likely is due to selection on protein electrophoretic characters that balances allozyme frequencies in the face of severe constraints to gene flow. These results raise a cautionary note for studies that rely on assumptions of neutrality for allozyme markers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karl, S A -- Avise, J C -- New York, N.Y. -- Science. 1992 Apr 3;256(5053):100-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1348870" target="_blank"〉PubMed〈/a〉

    Aromatase enzyme activity and sex determination in chickens (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-01-24
    Description: During development, the genotype of the zygote determines the nature of the gonad, which then determines the male or female phenotype. The molecular events underlying this process are just beginning to be defined. A single treatment of chicken embryos with an aromatase inhibitor (which blocks the synthesis of estrogen from testosterone) at a stage when their gonads were bipotential caused genetic females to develop a permanent male phenotype. These sex-reversed females developed bilateral testes that were capable of complete spermatogenesis and had the physical appearance and behavior of normal males. This result identifies aromatase as a key developmental switch in the sex determination of chickens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Elbrecht, A -- Smith, R G -- New York, N.Y. -- Science. 1992 Jan 24;255(5043):467-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Animal Biochemistry and Molecular Biology, Merck Sharp and Dohme Research Laboratories, Rahway, NJ 07065.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1734525" target="_blank"〉PubMed〈/a〉

    Structure and functional expression of an omega-conotoxin-sensitive human N-type calcium channel (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-07-17
    Description: N-type calcium channels are omega-conotoxin (omega-CgTx)-sensitive, voltage-dependent ion channels involved in the control of neurotransmitter release from neurons. Multiple subtypes of voltage-dependent calcium channel complexes exist, and it is the alpha 1 subunit of the complex that forms the pore through which calcium enters the cell. The primary structures of human neuronal calcium channel alpha 1B subunits were deduced by the characterization of overlapping complementary DNAs. Two forms (alpha 1B-1 and alpha 1B-2) were identified in human neuroblastoma (IMR32) cells and in the central nervous system, but not in skeletal muscle or aorta tissues. The alpha 1B-1 subunit directs the recombinant expression of N-type calcium channel activity when it is transiently co-expressed with human neuronal beta 2 and alpha 2b subunits in mammalian HEK293 cells. The recombinant channel was irreversibly blocked by omega-CgTx but was insensitive to dihydropyridines. The alpha 1B-1 alpha 2b beta 2-transfected cells displayed a single class of saturable, high-affinity (dissociation constant = 55 pM) omega-CgTx binding sites. Co-expression of the beta 2 subunit was necessary for N-type channel activity, whereas the alpha 2b subunit appeared to modulate the expression of the channel. The heterogeneity of alpha 1B subunits, along with the heterogeneity of alpha 2 and beta subunits, is consistent with multiple, biophysically distinct N-type calcium channels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, M E -- Brust, P F -- Feldman, D H -- Patthi, S -- Simerson, S -- Maroufi, A -- McCue, A F -- Velicelebi, G -- Ellis, S B -- Harpold, M M -- New York, N.Y. -- Science. 1992 Jul 17;257(5068):389-95.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉SIBIA, Inc., La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1321501" target="_blank"〉PubMed〈/a〉

    Description: A histone, macroH2A, nearly three times the size of conventional H2A histone, was found in rat liver nucleosomes. Its N-terminal third is 64 percent identical to a full-length mouse H2A. However, it also contains a large nonhistone region. This region has a segment that resembles a leucine zipper, a structure known to be involved in dimerization of some transcription factors. Nucleosomes containing macroH2A may have novel functions, possibly involving interactions with other nuclear proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pehrson, J R -- Fried, V A -- CA 06927/CA/NCI NIH HHS/ -- GM 24019/GM/NIGMS NIH HHS/ -- RR 05539/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1992 Sep 4;257(5075):1398-400.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Fox Chase Cancer Center, Institute for Cancer Research, Philadelphia, PA 19111.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1529340" target="_blank"〉PubMed〈/a〉

    Synaptotagmin: a calcium sensor on the synaptic vesicle surface (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-05-15
    Description: Neurons release neurotransmitters by calcium-dependent exocytosis of synaptic vesicles. However, the molecular steps transducing the calcium signal into membrane fusion are still an enigma. It is reported here that synaptotagmin, a highly conserved synaptic vesicle protein, binds calcium at physiological concentrations in a complex with negatively charged phospholipids. This binding is specific for calcium and involves the cytoplasmic domain of synaptotagmin. Calcium binding is dependent on the intact oligomeric structure of synaptotagmin (it is abolished by proteolytic cleavage at a single site). These results suggest that synaptotagmin acts as a cooperative calcium receptor in exocytosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brose, N -- Petrenko, A G -- Sudhof, T C -- Jahn, R -- New York, N.Y. -- Science. 1992 May 15;256(5059):1021-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurochemistry, Max-Planck-Institute for Psychiatry, Martinsried, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1589771" target="_blank"〉PubMed〈/a〉

    Calcium-dependent transmitter secretion reconstituted in Xenopus oocytes: requirement for synaptophysin (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-07-31
    Description: Calcium-dependent glutamate secretion was reconstituted in Xenopus oocytes by injecting the oocyte with total rat cerebellar messenger RNA (mRNA). Co-injection of total mRNA with antisense oligonucleotides to synaptophysin message decreased the expression of synaptophysin in the oocyte and reduced the calcium-dependent secretion. A similar effect on secretion was observed for oocytes injected with total mRNA together with an antibody to rat synaptophysin. These results indicate that synaptophysin is necessary for transmitter secretion and that the oocyte expression system may be useful for dissecting the molecular events associated with the secretory process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alder, J -- Lu, B -- Valtorta, F -- Greengard, P -- Poo, M M -- MH 39327/MH/NIMH NIH HHS/ -- NS 22764/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1992 Jul 31;257(5070):657-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Columbia University, New York, NY 10027.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1353905" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-01-17
    Description: Hormones inhibit synthesis of adenosine 3',5'-monophosphate (cAMP) in most cells via receptors coupled to pertussis toxin (PTX)-sensitive guanine nucleotide-binding (G) proteins. Mutationally activated alpha subunits of Gi2 (alpha i2) constitutively inhibit cAMP accumulation when transfected into cells. Cells have now been transfected with mutant alpha subunits of four other G proteins--Gz, a PTX-insensitive G protein of unknown function, and Gi1, Gi3, and G(o), which are PTX-sensitive. Mutant alpha z, alpha i1, and alpha i3 inhibited cAMP accumulation but alpha o did not. Moreover, expression of wild-type alpha z produced cells in which PTX did not block hormonal inhibition of cAMP accumulation. Thus, Gz can trigger an effector pathway in response to hormone receptors that ordinarily interact with PTX-sensitive Gi proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wong, Y H -- Conklin, B R -- Bourne, H R -- New York, N.Y. -- Science. 1992 Jan 17;255(5042):339-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1347957" target="_blank"〉PubMed〈/a〉

    Lymphoid development in mice congenitally lacking T cell receptor alpha beta-expressing cells (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-06-05
    Description: Vertebrate T cells express either an alpha beta or gamma delta T cell receptor (TCR). The developmental relatedness of the two cell types is unresolved. alpha beta + T cells respond to specific pathogens by collaborating with immunoglobulin-producing B cells in distinct lymphoid organs such as the spleen and Peyer's patches. The precise influence of alpha beta + T cells on B cell development is poorly understood. To investigate the developmental effects of alpha beta + T cells on B cells and gamma delta + T cells, mice homozygous for a disrupted TCR alpha gene were generated. The homozygotes showed elimination of alpha beta + T cells and the loss of thymic medullae. Despite this, gamma delta + T cells developed in normal numbers, and there was an increase in splenic B cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Philpott, K L -- Viney, J L -- Kay, G -- Rastan, S -- Gardiner, E M -- Chae, S -- Hayday, A C -- Owen, M J -- GM37759/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1992 Jun 5;256(5062):1448-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Imperial Cancer Research Fund, London, United Kingdom.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1604321" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-03-27
    Description: A slowly activating, voltage-dependent potassium channel protein cloned from rat kidney was expressed in Xenopus oocytes. Two activators of protein kinase C, 1-oleoyl-2-acetyl-rac-glycerol and phorbol 12,13-didecanoate, inhibited the current. This inhibition was blocked by the kinase inhibitor staurosporine. Inhibition of the current was not seen in channels in which Ser103 was replaced by Ala, although other properties of the current were unchanged. These results indicate that inhibition of the potassium current results from direct phosphorylation of the channel subunit protein at Ser103.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Busch, A E -- Varnum, M D -- North, R A -- Adelman, J P -- DA03160/DA/NIDA NIH HHS/ -- NS28504/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1992 Mar 27;255(5052):1705-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vollum Institute, Oregon Health Sciences University, Portland 97201.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1553557" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1992-08-21
    Description: Cystic fibrosis results from defects in the gene encoding a cyclic adenosine monophosphate-dependent chloride ion channel known as the cystic fibrosis transmembrane conductance regulator (CFTR). To create an animal model for cystic fibrosis, mice were generated from embryonic stem cells in which the CFTR gene was disrupted by gene targeting. Mice homozygous for the disrupted gene display many features common to young human cystic fibrosis patients, including failure to thrive, meconium ileus, alteration of mucous and serous glands, and obstruction of glandlike structures with inspissated eosinophilic material. Death resulting from intestinal obstruction usually occurs before 40 days of age.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Snouwaert, J N -- Brigman, K K -- Latour, A M -- Malouf, N N -- Boucher, R C -- Smithies, O -- Koller, B H -- GM20069/GM/NIGMS NIH HHS/ -- HL 42384/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1992 Aug 21;257(5073):1083-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of North Carolina, Chapel Hill 27599-7020.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1380723" target="_blank"〉PubMed〈/a〉

    Trypsin-sensitive, rapid inactivation of a calcium-activated potassium channel (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-09-18
    Description: Most calcium-activated potassium channels couple changes in intracellular calcium to membrane excitability by conducting a current with a probability that depends directly on submembrane calcium concentration. In rat adrenal chromaffin cells, however, a large conductance, voltage- and calcium-activated potassium channel (BK) undergoes rapid inactivation, suggesting that this channel has a physiological role different than that of other BK channels. The inactivation of the BK channel, like that of the voltage-gated Shaker B potassium channel, is removed by trypsin digestion and channels are blocked by the Shaker B amino-terminal inactivating domain. Thus, this BK channel shares functional and possibly structural homologies with other inactivating voltage-gated potassium channels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Solaro, C R -- Lingle, C J -- New York, N.Y. -- Science. 1992 Sep 18;257(5077):1694-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anesthesiology, Washington University School of Medicine, St. Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1529355" target="_blank"〉PubMed〈/a〉

    Mutation of the POU-specific domain of Pit-1 and hypopituitarism without pituitary hypoplasia (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-08-21
    Description: A point mutation in the POU-specific portion of the human gene that encodes the tissue-specific POU-domain transcription factor, Pit-1, results in hypopituitarism, with deficiencies of growth hormone, prolactin, and thyroid-stimulating hormone. In two unrelated Dutch families, a mutation in Pit-1 that altered an alanine in the first putative alpha helix of the POU-specific domain to proline was observed. This mutation generated a protein capable of binding to DNA response elements but unable to effectively activate its known target genes, growth hormone and prolactin. The phenotype of the affected individuals suggests that the mutant Pit-1 protein is competent to initiate other programs of gene activation required for normal proliferation of somatotrope, lactotrope, and thyrotrope cell types. Thus, a mutation in the POU-specific domain of Pit-1 has a selective effect on a subset of Pit-1 target genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pfaffle, R W -- DiMattia, G E -- Parks, J S -- Brown, M R -- Wit, J M -- Jansen, M -- Van der Nat, H -- Van den Brande, J L -- Rosenfeld, M G -- Ingraham, H A -- HD24960/HD/NICHD NIH HHS/ -- HD2697/HD/NICHD NIH HHS/ -- NIDDK 18477/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1992 Aug 21;257(5073):1118-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, Emory University School of Medicine, Atlanta, GA 30322.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1509263" target="_blank"〉PubMed〈/a〉

    Calcium-permeable AMPA-kainate receptors in fusiform cerebellar glial cells (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-06-12
    Description: Glutamate-operated ion channels (GluR channels) of the L-alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-kainate subtype are found in both neurons and glial cells of the central nervous system. These channels are assembled from the GluR-A, -B, -C, and -D subunits; channels containing a GluR-B subunit show an outwardly rectifying current-voltage relation and low calcium permeability, whereas channels lacking the GluR-B subunit are characterized by a doubly rectifying current-voltage relation and high calcium permeability. Most cell types in the central nervous system coexpress several subunits, including GluR-B. However, Bergmann glia in rat cerebellum do not express GluR-B subunit genes. In a subset of cultured cerebellar glial cells, likely derived from Bergmann glial cells. GluR channels exhibit doubly rectifying current-voltage relations and high calcium permeability, whereas GluR channels of cerebellar neurons have low calcium permeability. Thus, differential expression of the GluR-B subunit gene in neurons and glia is one mechanism by which functional properties of native GluR channels are regulated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burnashev, N -- Khodorova, A -- Jonas, P -- Helm, P J -- Wisden, W -- Monyer, H -- Seeburg, P H -- Sakmann, B -- New York, N.Y. -- Science. 1992 Jun 12;256(5063):1566-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur Medizinische Forschung, Abteilung Zellphysiologie, Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1317970" target="_blank"〉PubMed〈/a〉

    Control by asparagine residues of calcium permeability and magnesium blockade in the NMDA receptor (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-09-04
    Description: The N-methyl-D-aspartate (NMDA) receptor forms a cation-selective channel with a high calcium permeability and sensitivity to channel block by extracellular magnesium. These properties, which are believed to be important for the induction of long-term changes in synaptic strength, are imparted by asparagine residues in a putative channel-forming segment of the protein, transmembrane 2 (TM2). In the NR1 subunit, replacement of this asparagine by a glutamine residue decreases calcium permeability of the channel and slightly reduces magnesium block. The same substitution in NR2 subunits strongly reduces magnesium block and increases the magnesium permeability but barely affects calcium permeability. These asparagines are in a position homologous to the site in the TM2 region (Q/R site) of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors that is occupied by either glutamine (Q) or arginine (R) and that controls divalent cation permeability of the AMPA receptor channel. Hence AMPA and NMDA receptor channels contain common structural motifs in their TM2 segments that are responsible for some of their ion selectivity and conductance properties.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burnashev, N -- Schoepfer, R -- Monyer, H -- Ruppersberg, J P -- Gunther, W -- Seeburg, P H -- Sakmann, B -- New York, N.Y. -- Science. 1992 Sep 4;257(5075):1415-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Abteilung Zellphysiologie, 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/1382314" target="_blank"〉PubMed〈/a〉
