    Role of intracellular calcium in NI-35-evoked collapse of neuronal growth cones (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-01-01
    Description: A myelin-associated protein from the central nervous system, the neurite growth inhibitor NI-35, inhibits regeneration of lesioned neuronal fiber tracts in vivo and growth of neurites in vitro. Growth cones of cultured rat dorsal root ganglion neurons arrested their growth and collapsed when exposed to liposomes containing NI-35. Before morphological changes, the concentration of free intracellular calcium ([Ca2+]i) showed a rapid and large increase in growth cones exposed to liposomes containing NI-35. Neither an increase in [Ca2+]i nor collapse of growth cones was detected in the presence of antibodies to NI-35. Dantrolene, an inhibitor of calcium release from caffeine-sensitive intracellular calcium stores, protected growth cones from collapse evoked by NI-35. Depletion of these caffeine-sensitive intracellular calcium stores prevented the increase in [Ca2+]i evoked by NI-35. The NI-35-evoked cascade of intracellular messengers that mediates collapse of growth cones includes the crucial step of calcium release from intracellular stores.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bandtlow, C E -- Schmidt, M F -- Hassinger, T D -- Schwab, M E -- Kater, S B -- NS24683/NS/NINDS NIH HHS/ -- NS28323/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1993 Jan 1;259(5091):80-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Brain Research Institute, University of Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8418499" target="_blank"〉PubMed〈/a〉

    Rate and mechanism of nonhomologous recombination during a single cycle of retroviral replication (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-01-08
    Description: Oncogenes discovered in retroviruses such as Rous sarcoma virus were generated by transduction of cellular proto-oncogenes into the viral genome. Several different kinds of junctions between the viral and proto-oncogene sequences have been found in different viruses. A system of retrovirus vectors and a protocol that mimicked this transduction during a single cycle of retrovirus replication was developed. The transduction involved the formation of a chimeric viral-cellular RNA, strand switching of the reverse transcription growing point from an infectious retrovirus to the chimeric RNA, and often a subsequent deletion during the rest of viral DNA synthesis. A short region of sequence identity was frequently used for the strand switching. The rate of this process was about 0.1 to 1 percent of the rate of homologous retroviral recombination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, J -- Temin, H M -- CA-07175/CA/NCI NIH HHS/ -- CA-22443/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1993 Jan 8;259(5092):234-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉McArdle Laboratory for Cancer Research, University of Wisconsin-Madison 53706.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8421784" target="_blank"〉PubMed〈/a〉

    Expression cloning and signaling properties of the rat glucagon receptor (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-03-12
    Description: Glucagon and the glucagon receptor are a primary source of control over blood glucose concentrations and are especially important to studies of diabetes in which the loss of control over blood glucose concentrations clinically defines the disease. A complementary DNA clone for the glucagon receptor was isolated by an expression cloning strategy, and the receptor protein was expressed in several kidney cell lines. The cloned receptor bound glucagon and caused an increase in the intracellular concentration of adenosine 3', 5'-monophosphate (cAMP). The cloned glucagon receptor also transduced a signal that led to an increased concentration of intracellular calcium. The glucagon receptor is similar to the calcitonin and parathyroid hormone receptors. It can transduce signals leading to the accumulation of two different second messengers, cAMP and calcium.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jelinek, L J -- Lok, S -- Rosenberg, G B -- Smith, R A -- Grant, F J -- Biggs, S -- Bensch, P A -- Kuijper, J L -- Sheppard, P O -- Sprecher, C A -- New York, N.Y. -- Science. 1993 Mar 12;259(5101):1614-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉ZymoGenetics Inc., Seattle, WA 98105.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8384375" target="_blank"〉PubMed〈/a〉

    Formation of a molten globule intermediate early in the kinetic folding pathway of apomyoglobin (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-11-05
    Description: Hydrogen exchange pulse labeling and stopped-flow circular dichroism were used to establish that the structure of the earliest detectable intermediate formed during refolding of apomyoglobin corresponds closely to that of a previously characterized equilibrium molten globule. This compact, cooperatively folded intermediate was formed in less than 5 milliseconds and contained stable, hydrogen-bonded secondary structure localized in the A, G, and H helices and part of the B helix. The remainder of the B helix folded on a much slower time scale, followed by the C and E helices and the CD loop. The data indicate that a molten globule intermediate was formed on the kinetic folding pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jennings, P A -- Wright, P E -- DK-34909/DK/NIDDK NIH HHS/ -- GM14541/GM/NIGMS NIH HHS/ -- RR04953/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1993 Nov 5;262(5135):892-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Scripps Research Institute, La Jolla, California 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8235610" target="_blank"〉PubMed〈/a〉

    Isolation of new ribozymes from a large pool of random sequences [see comment] (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-09-10
    Description: An iterative in vitro selection procedure was used to isolate a new class of catalytic RNAs (ribozymes) from a large pool of random-sequence RNA molecules. These ribozymes ligate two RNA molecules that are aligned on a template by catalyzing the attack of a 3'-hydroxyl on an adjacent 5'-triphosphate--a reaction similar to that employed by the familiar protein enzymes that synthesize RNA. The corresponding uncatalyzed reaction also yields a 3',5'-phosphodiester bond. In vitro evolution of the population of new ribozymes led to improvement of the average ligation activity and the emergence of ribozymes with reaction rates 7 million times faster than the uncatalyzed reaction rate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bartel, D P -- Szostak, J W -- New York, N.Y. -- Science. 1993 Sep 10;261(5127):1411-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Massachusetts General Hospital, Boston 02114.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7690155" target="_blank"〉PubMed〈/a〉

    Altered fluid transport across airway epithelium in cystic fibrosis (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-10-15
    Description: In cystic fibrosis (CF), absence or dysfunction of a phosphorylation-regulated chloride channel [CF transmembrane conductance regulator (CFTR)] leads to the loss or reduction of chloride secretion into the airways. Active sodium absorption is also increased in CF, and both of these ion transport changes could alter fluid transport across the airways. Under baseline conditions, cultured human airway epithelia from normal individuals absorbed fluid, and this absorption was increased in epithelia from patients with CF. In normal and CF epithelial cultures fluid absorption was inhibited by amiloride. Adenosine 3',5'-monophosphate stimulated fluid secretion in normal epithelial cultures but not in cultures from individuals with CF. In contrast, fluid secretion induced by nucleotide triphosphates (uridine triphosphate or adenosine triphosphate) was unaltered in cultures of epithelia from patients with CF, suggesting an approach to the treatment of CF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jiang, C -- Finkbeiner, W E -- Widdicombe, J H -- McCray, P B Jr -- Miller, S S -- HL 42368/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1993 Oct 15;262(5132):424-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8211164" target="_blank"〉PubMed〈/a〉

    Modal shifts in acetylcholine receptor channel gating confer subunit-dependent desensitization (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-06-18
    Description: During the transition from embryonic to adult skeletal muscle, a decreased mean channel open time and accelerated desensitization of nicotinic acetylcholine (ACh) receptors result from the substitution of an epsilon subunit for gamma. A single ACh receptor channel of the embryonic type, expressed in Xenopus oocytes, interconverts between gating modes of short and long open time, whereas the adult receptor channel resides almost exclusively in the gating mode with short open time. Differences in the fraction of time spent in either gating mode account for the subunit dependence of both receptor open time and desensitization. Therefore, developmental changes in the kinetics of muscle ACh receptors may be imparted through subunit-dependent stabilization of intrinsic gating modes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Naranjo, D -- Brehm, P -- NS18205/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1993 Jun 18;260(5115):1811-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology and Behavior, State University of New York, Stony Brook 11794.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8511590" target="_blank"〉PubMed〈/a〉

    Requirement for a GTPase-activating protein in vesicle budding from the endoplasmic reticulum (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-03-05
    Description: The binding and hydrolysis of guanosine triphosphate (GTP) by the small GTP-binding protein Sar1p is required to form transport vesicles from the endoplasmic reticulum (ER) in Saccharomyces cerevisiae. Experiments revealed that an interaction between Sar1p and the Sec23p subunit of an oligomeric protein is also required for vesicle budding. The isolated Sec23p subunit and the oligomeric complex stimulated guanosine triphosphatase (GTPase) activity of Sar1p 10- to 15-fold but did not activate two other small GTP-binding proteins involved in vesicle traffic (Ypt1p and ARF). Activation of GTPase was inhibited by an antibody to Sec23p but not by an antibody that inhibits the budding activity of the other subunit of the Sec23p complex. Also, activation was thermolabile in pure samples of Sec23p that were isolated from two independent sec23 mutant strains. It appears that Sec23p represents a new class of GTPase-activating protein because its sequence shows no similarity to any known member of this family.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoshihisa, T -- Barlowe, C -- Schekman, R -- New York, N.Y. -- Science. 1993 Mar 5;259(5100):1466-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular and Cell Biology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8451644" target="_blank"〉PubMed〈/a〉

    GDNF: a glial cell line-derived neurotrophic factor for midbrain dopaminergic neurons (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-05-21
    Description: A potent neurotrophic factor that enhances survival of midbrain dopaminergic neurons was purified and cloned. Glial cell line-derived neurotrophic factor (GDNF) is a glycosylated, disulfide-bonded homodimer that is a distantly related member of the transforming growth factor-beta superfamily. In embryonic midbrain cultures, recombinant human GDNF promoted the survival and morphological differentiation of dopaminergic neurons and increased their high-affinity dopamine uptake. These effects were relatively specific; GDNF did not increase total neuron or astrocyte numbers nor did it increase transmitter uptake by gamma-aminobutyric-containing and serotonergic neurons. GDNF may have utility in the treatment of Parkinson's disease, which is marked by progressive degeneration of midbrain dopaminergic neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, L F -- Doherty, D H -- Lile, J D -- Bektesh, S -- Collins, F -- New York, N.Y. -- Science. 1993 May 21;260(5111):1130-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Synergen, Inc., Boulder, CO 80301.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8493557" target="_blank"〉PubMed〈/a〉

    Probing the mechanism of staphylococcal nuclease with unnatural amino acids: kinetic and structural studies (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-09-17
    Description: Staphylococcal nuclease is an enzyme with enormous catalytic power, accelerating phosphodiester bond hydrolysis by a factor of 10(16) over the spontaneous rate. The mechanistic basis for this rate acceleration was investigated by substitution of the active site residues Glu43, Arg35, and Arg87 with unnatural amino acid analogs. Two Glu43 mutants, one containing the nitro analog of glutamate and the other containing homoglutamate, retained high catalytic activity at pH 9.9, but were less active than the wild-type enzyme at lower pH values. The x-ray crystal structure of the homoglutamate mutant revealed that the carboxylate side chain of this residue occupies a position and orientation similar to that of Glu43 in the wild-type enzyme. The increase in steric bulk is accommodated by a backbone shift and altered torsion angles. The nitro and the homoglutamate mutants display similar pH versus rate profiles, which differ from that of the wild-type enzyme. Taken together, these studies suggest that Glu43 may not act as a general base, as previously thought, but may play a more complex structural role during catalysis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Judice, J K -- Gamble, T R -- Murphy, E C -- de Vos, A M -- Schultz, P G -- GM 14012-02S1/GM/NIGMS NIH HHS/ -- R01 GM49220/GM/NIGMS NIH HHS/ -- T32GM-08388/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1993 Sep 17;261(5128):1578-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8103944" target="_blank"〉PubMed〈/a〉

    Enhancement by histamine of NMDA-mediated synaptic transmission in the hippocampus (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-07-02
    Description: Histamine is a neuromodulator in the brain, and the hippocampus is one of the regions of the brain that is innervated by histaminergic neurons. When applied to cultured hippocampal neurons, histamine selectively increased by up to tenfold the amplitude of the component of synaptic transmission that was mediated by N-methyl-D-aspartate (NMDA) receptors. Spontaneous miniature synaptic currents and the current elicited by applied NMDA also were enhanced, indicating that the histamine effect was expressed primarily postsynaptically. These results suggest that histamine may modulate processes involving NMDA receptors, such as the induction of long-term potentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bekkers, J M -- New York, N.Y. -- Science. 1993 Jul 2;261(5117):104-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neuroscience, John Curtin School of Medical Research, Australian National Univresity, Canberra, ACT.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8391168" target="_blank"〉PubMed〈/a〉

    Description: Protein phosphatases play important roles in the regulation of cell growth and metabolism, yet little is known about their enzymatic mechanism. By extrapolation from data on inhibitors of other types of hydrolases, an inhibitor of prostatic acid phosphatase was designed that is likely to function as a mechanism-based phosphotyrosine phosphatase inactivator. This molecule, 4-(fluoromethyl)phenyl phosphate, represents a useful paradigm for the design of potent and specific phosphatase inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Myers, J K -- Widlanski, T S -- R01 GM47918-01/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1993 Nov 26;262(5138):1451-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Indiana University, Bloomington 47405.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8248785" target="_blank"〉PubMed〈/a〉

    Interleukin-7: a cofactor for V(D)J rearrangement of the T cell receptor beta gene (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-07-02
    Description: The diversity of the T cell receptor repertoire is generated by rearrangement of gene elements in immature thymocytes. To identify a thymic signal that induces this rearrangement, a variety of agents were tested for their ability to induce rearrangement of the T cell receptor beta gene in suspensions of thymocytes from mouse embryos at day 14 of gestation. Of 16 agents tested, only interleukin-7 (IL-7) induced V(D)J gene rearrangement and sustained expression of the RAG-1 and RAG-2 genes, which are known to control rearrangement. These data implicate IL-7, a cytokine that is abundantly expressed in embryonic thymus, in driving gene rearrangement during early T cell development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Muegge, K -- Vila, M P -- Durum, S K -- New York, N.Y. -- Science. 1993 Jul 2;261(5117):93-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biological Carcinogenesis and Development Program, Program Resources Inc./Dyncorp, National Cancer Institute-Frederick Cancer Research and Development Center, MD 21702.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7686307" target="_blank"〉PubMed〈/a〉

    Neuroprotective effects of glutamate antagonists and extracellular acidity (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-06-04
    Description: Glutamate antagonists protect neurons from hypoxic injury both in vivo and in vitro, but in vitro studies have not been done under the acidic conditions typical of hypoxia-ischemia in vivo. Consistent with glutamate receptor antagonism, extracellular acidity reduced neuronal death in murine cortical cultures that were deprived of oxygen and glucose. Under these acid conditions, N-methyl-D-aspartate and alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate-kainate antagonists further reduced neuronal death, such that some neurons tolerated prolonged oxygen and glucose deprivation almost as well as did astrocytes. Neuroprotection induced by this combination exceeded that induced by glutamate antagonists alone, suggesting that extracellular acidity has beneficial effects beyond the attenuation of ionotropic glutamate receptor activation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaku, D A -- Giffard, R G -- Choi, D W -- NS 01425/NS/NINDS NIH HHS/ -- NS 26907/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1993 Jun 4;260(5113):1516-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology and Neurological Sciences, Stanford University School of Medicine, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8389056" target="_blank"〉PubMed〈/a〉

    Antagonism of catecholamine receptor signaling by expression of cytoplasmic domains of the receptors (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-03-05
    Description: The actions of many hormones and neurotransmitters are mediated by the members of a superfamily of receptors coupled to heterotrimeric guanine nucleotide-binding proteins (G proteins). These receptors are characterized by a highly conserved topographical arrangement in which seven transmembrane domains are connected by intracellular and extracellular loops. The interaction between these receptors and G proteins is mediated in large part by the third intracellular loop of the receptor. Coexpression of the third intracellular loop of the alpha 1B-adrenergic receptor with its parent receptor inhibited receptor-mediated activation of phospholipase C. The inhibition extended to the closely related alpha 1C-adrenergic receptor subtype, but not the phospholipase C-coupled M1 muscarinic acetylcholine receptor nor the adenylate cyclase-coupled D1A dopamine receptor. These results suggest that the receptor-G protein interface may represent a target for receptor antagonist drugs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Luttrell, L M -- Ostrowski, J -- Cotecchia, S -- Kendall, H -- Lefkowitz, R J -- HL16037/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1993 Mar 5;259(5100):1453-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Duke University Medical Center, Durham, NC 27710.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8383880" target="_blank"〉PubMed〈/a〉

    Inhibition of viral replication by interferon-gamma-induced nitric oxide synthase (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-09-10
    Description: Interferons (IFNs) induce antiviral activity in many cell types. The ability of IFN-gamma to inhibit replication of ectromelia, vaccinia, and herpes simplex-1 viruses in mouse macrophages correlated with the cells' production of nitric oxide (NO). Viral replication was restored in IFN-gamma-treated macrophages exposed to inhibitors of NO synthase. Conversely, epithelial cells with no detectable NO synthesis restricted viral replication when transfected with a complementary DNA encoding inducible NO synthase or treated with organic compounds that generate NO. In mice, an inhibitor of NO synthase converted resolving ectromelia virus infection into fulminant mousepox. Thus, induction of NO synthase can be necessary and sufficient for a substantial antiviral effect of IFN-gamma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karupiah, G -- Xie, Q W -- Buller, R M -- Nathan, C -- Duarte, C -- MacMicking, J D -- CA43610/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1993 Sep 10;261(5127):1445-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Viral Diseases, 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/7690156" target="_blank"〉PubMed〈/a〉

    Developmental regulation of neural response to FGF-1 and FGF-2 by heparan sulfate proteoglycan (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-04-02
    Description: Murine neural precursor cells and cell lines derived from them are stimulated by members of the heparin-binding fibroblast growth factor (FGF) family. The activity of FGF is regulated by heparan sulfate proteoglycans (HSPGs), and this interaction is an essential prerequisite for the binding of growth factor to the signal transducing receptors. Messenger RNA for FGF-2 was detectable in the neuroepithelium at embryonic day 9, and the HSPGs produced by these cells at this time preferentially bound FGF-2. However, at embryonic day 11, when messenger RNA for FGF-1 was first detectable, there was a switch in the binding specificity of the HSPG to FGF-1. Thus, a single species of HSPG undergoes a rapid, tightly controlled change in growth factor-binding specificity concomitant with the temporal expression of the FGFs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nurcombe, V -- Ford, M D -- Wildschut, J A -- Bartlett, P F -- New York, N.Y. -- Science. 1993 Apr 2;260(5104):103-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Cell Biology, University of Melbourne, Parkville, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7682010" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-10-15
    Description: Unlike most serine proteases of the chymotrypsin family, tissue-type plasminogen activator (tPA) is secreted from cells as an active, single-chain enzyme with a catalytic efficiency only slightly lower than that of the proteolytically cleaved form. A zymogenic mutant of tPA has been engineered that displays a reduction in catalytic efficiency by a factor of 141 in the single-chain form while retaining full activity in the cleaved form. The residues introduced in the mutant, serine 292 and histidine 305, are proposed to form a hydrogen-bonded network with aspartate 477, similar to the aspartate 194-histidine 40-serine 32 network found to stabilize the zymogen chymotrypsinogen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Madison, E L -- Kobe, A -- Gething, M J -- Sambrook, J F -- Goldsmith, E J -- New York, N.Y. -- Science. 1993 Oct 15;262(5132):419-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, 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/8211162" target="_blank"〉PubMed〈/a〉

    Separate GTP binding and GTPase activating domains of a G alpha subunit (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-12-17
    Description: Most members of the guanosine triphosphatase (GTPase) superfamily hydrolyze guanosine triphosphate (GTP) quite slowly unless stimulated by a GTPase activating protein or GAP. The alpha subunits (G alpha) of the heterotrimeric G proteins hydrolyze GTP much more rapidly and contain an approximately 120-residue insert not found in other GTPases. Interactions between a G alpha insert domain and a G alpha GTP-binding core domain, both expressed as recombinant proteins, show that the insert acts biochemically as a GAP. The results suggest a general mechanism for GAP-dependent hydrolysis of GTP by other GTPases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Markby, D W -- Onrust, R -- Bourne, H R -- 5F32-GM13918/GM/NIGMS NIH HHS/ -- CA54427/CA/NCI NIH HHS/ -- GM27800/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1993 Dec 17;262(5141):1895-901.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmcology, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8266082" target="_blank"〉PubMed〈/a〉

    Beta-adrenergic receptor kinase-2 and beta-arrestin-2 as mediators of odorant-induced desensitization (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-02-05
    Description: beta-Adrenergic receptor kinase (beta ARK) and beta-arrestin function in the homologous or agonist-activated desensitization of G protein-coupled receptors. The isoforms beta ARK-2 and beta-arrestin-2 are highly enriched in and localized to the dendritic knobs and cilia of the olfactory receptor neurons where the initial events of olfactory signal transduction occur. Odorants induce a rapid and transient elevation of adenosine 3',5'-monophosphate (cAMP), which activates a nonspecific cation channel and produces membrane depolarization. Preincubation of rat olfactory cilia with antibodies raised against beta ARK-2 and beta-arrestin-2 increased the odorant-induced elevation of cAMP and attenuated desensitization. These results suggest that beta ARK-2 and beta-arrestin-2 mediate agonist-dependent desensitization in olfaction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dawson, T M -- Arriza, J L -- Jaworsky, D E -- Borisy, F F -- Attramadal, H -- Lefkowitz, R J -- Ronnett, G V -- NS 01578-01/NS/NINDS NIH HHS/ -- NS-02131/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1993 Feb 5;259(5096):825-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience, Johns Hopkins Medical Institutions, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8381559" target="_blank"〉PubMed〈/a〉

    Proliferation of human smooth muscle cells promoted by lipoprotein(a) (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-06-11
    Description: Elevated blood concentrations of lipoprotein(a) [Lp(a)] and its constituent, apolipoprotein(a) [apo(a)], constitute a major risk factor for atherosclerosis, but their physiological activities remain obscure. Lp(a) and purified apo(a) stimulated the growth of human smooth muscle cells in culture. This effect resulted from inhibition of plasminogen activation, and consequently the activation by plasmin of latent transforming growth factor-beta, which is an inhibitor of smooth muscle cell growth. Because smooth muscle proliferation is one of the hallmarks of atherosclerotic lesions, these results point to a plausible mechanism for the atherogenic activity of Lp(a).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grainger, D J -- Kirschenlohr, H L -- Metcalfe, J C -- Weissberg, P L -- Wade, D P -- Lawn, R M -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1993 Jun 11;260(5114):1655-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Cambridge, United Kingdom.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8503012" target="_blank"〉PubMed〈/a〉

    Kinetics of folding of the all-beta sheet protein interleukin-1 beta (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-05-21
    Description: The folding of the all-beta sheet protein, interleukin-1 beta, was studied with nuclear magnetic resonance (NMR) spectroscopy, circular dichroism, and fluorescence. Ninety percent of the beta structure present in the native protein, as monitored by far-ultraviolet circular dichroism, was attained within 25 milliseconds, correlating with the first kinetic phase determined by tryptophan and 1-anilinonaphthalene-8-sulfonate fluorescence. In contrast, formation of stable native secondary structure, as measured by quenched-flow deuterium-hydrogen exchange experiments, began after only 1 second. Results from the NMR experiments indicated the formation of at least two intermediates with half-lives of 0.7 to 1.5 and 15 to 25 seconds. The final stabilization of the secondary structure, however, occurs on a time scale much greater than 25 seconds. These results differ from previous results on mixed alpha helix-beta sheet proteins in which both the alpha helices and beta sheets were stabilized very rapidly (less than 10 to 20 milliseconds).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Varley, P -- Gronenborn, A M -- Christensen, H -- Wingfield, P T -- Pain, R H -- Clore, G M -- New York, N.Y. -- Science. 1993 May 21;260(5111):1110-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Chemical Physics, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health (NIH), Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8493553" target="_blank"〉PubMed〈/a〉

    Arrestin function in inactivation of G protein-coupled receptor rhodopsin in vivo (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-06-25
    Description: Arrestins have been implicated in the regulation of many G protein-coupled receptor signaling cascades. Mutations in two Drosophila photoreceptor-specific arrestin genes, arrestin 1 and arrestin 2, were generated. Analysis of the light response in these mutants shows that the Arr1 and Arr2 proteins are mediators of rhodopsin inactivation and are essential for the termination of the phototransduction cascade in vivo. The saturation of arrestin function by an excess of activated rhodopsin is responsible for a continuously activated state of the photoreceptors known as the prolonged depolarized afterpotential. In the absence of arrestins, photoreceptors undergo light-dependent retinal degeneration as a result of the continued activity of the phototransduction cascade. These results demonstrate the fundamental requirement for members of the arrestin protein family in the regulation of G protein-coupled receptors and signaling cascades in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dolph, P J -- Ranganathan, R -- Colley, N J -- Hardy, R W -- Socolich, M -- Zuker, C S -- R01 EY008768/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1993 Jun 25;260(5116):1910-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, La Jolla, CA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8316831" target="_blank"〉PubMed〈/a〉

    Description: An introduced whitefly species, responsible for over a half billion dollars in damage to U.S. agricultural production in 1991, is morphologically indistinguishable from Bemisia tabaci (Gennadius). However, with the use of polymerase chain reaction-based DNA differentiation tests, allozymic frequency analyses, crossing experiments, and mating behavior studies, the introduced whitefly is found to be a distinct species. Recognition of this new species, the silverleaf whitefly, is critical in the search for management options.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perring, T M -- Cooper, A D -- Rodriguez, R J -- Farrar, C A -- Bellows, T S Jr -- New York, N.Y. -- Science. 1993 Jan 1;259(5091):74-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomology, University of California, Riverside 92521.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8418497" target="_blank"〉PubMed〈/a〉

    A Ca-dependent early step in the release of catecholamines from adrenal chromaffin cells (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-11-12
    Description: Intense stimuli, such as trains of depolarizing pulses or the caffeine-induced release of calcium from intracellular stores, readily depress the secretory response in neuroendocrine cells. Secretory responses are restored by rest periods of minutes in duration. This recovery was accelerated when the concentration of cytosolic calcium was moderately increased and probably resulted from calcium-dependent replenishment of a pool of release-ready granules. Continuously increased concentrations of calcium led the over-filling of such a pool. Subsequently, secretory responses to stronger calcium stimuli were augmented. Hormone-induced calcium transients with a plateau phase of increased concentration of calcium may enhance the secretory response in this way.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉von Ruden, L -- Neher, E -- New York, N.Y. -- Science. 1993 Nov 12;262(5136):1061-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Membrane Biophysics, Max-Planck-Institut fur biophysikalische Chemie, Gottingen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8235626" target="_blank"〉PubMed〈/a〉

    Translocation of repetitive RNA sequences with the germ plasm in Xenopus oocytes (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-12-10
    Description: Xlsirts are a family of interspersed repeat RNAs from Xenopus laevis that contain from 3 to 13 repeat units (each 79 to 81 nucleotides long) flanked by unique sequences. They are homologous to the mammalian Xist gene that is involved in X chromosome inactivation. Xlsirt RNA appears first in the mitochondrial cloud (Balbiani body) in stage 2 oocytes and is then translocated as island-like structures to the vegetal cortex at early stage 3 coincident with the localization of the germ plasm. Exogenous Xlsirt RNA injected into oocytes translocates to the location of the endogenous RNA at that particular stage. The Xlsirt RNA repeat sequences are required for translocation and can cause the translocation of heterologous unique RNAs to the vegetal cortex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kloc, M -- Spohr, G -- Etkin, L D -- New York, N.Y. -- Science. 1993 Dec 10;262(5140):1712-4.〈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/7505061" target="_blank"〉PubMed〈/a〉

    Switch of CD8 T cells to noncytolytic CD8-CD4- cells that make TH2 cytokines and help B cells (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-06-18
    Description: CD8+ T cells are a major defense against viral infections and intracellular parasites. Their production of interferon-gamma (IFN-gamma) and their cytolytic activity are key elements in the immune response to these pathogens. Mature mouse CD8+ T cells that were activated in the presence of interleukin-4 (IL-4) developed into a CD8-CD4- population that was not cytolytic and did not produce IFN-gamma. However, these CD8- cells produced large amounts of IL-4, IL-5, and IL-10 and helped activate resting B cells. Thus, CD8 effector functions are potentially diverse and could be exploited by infectious agents that switch off host protective cytolytic responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Erard, F -- Wild, M T -- Garcia-Sanz, J A -- Le Gros, G -- New York, N.Y. -- Science. 1993 Jun 18;260(5115):1802-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Allergy/Immunology, Ciba-Geigy Ltd., Basel, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8511588" target="_blank"〉PubMed〈/a〉
