    Description: Voltage-gated sodium channels are responsible for generation of action potentials in excitable cells. Activation of protein kinase C slows inactivation of sodium channels and reduces peak sodium currents. Phosphorylation of a single residue, serine 1506, that is located in the conserved intracellular loop between domains III and IV and is involved in inactivation of the sodium channel, is required for both modulatory effects. Mutant sodium channels lacking this phosphorylation site have normal functional properties in unstimulated cells but do not respond to activation of protein kinase C. Phosphorylation of this conserved site in sodium channel alpha subunits may regulate electrical activity in a wide range of excitable cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉West, J W -- Numann, R -- Murphy, B J -- Scheuer, T -- Catterall, W A -- GM07270/GM/NIGMS NIH HHS/ -- NS15751/NS/NINDS NIH HHS/ -- NS25704/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1991 Nov 8;254(5033):866-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Washington, Seattle 98195.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1658937" target="_blank"〉PubMed〈/a〉

    Description: Mutations that cause pituitary dwarfism in the mouse reside in the gene encoding the transcription factor growth hormone factor 1 (GHF1 or pit1). These dwarf mice (dw and dwJ) are deficient in growth hormone (GH) and prolactin (PRL) synthesis and exhibit pituitary hypoplasia, suggesting a stem cell defect. With antisense oligonucleotide technology, a cell culture model of this genetic defect was developed. Specific inhibition of GHF1 synthesis by complementary oligonucleotides led to a marked decrease in GH and PRL expression and to a marked decrease in proliferation of somatotrophic cell lines. These results provide direct evidence that the homeodomain protein GHF1 is required not only for the establishment and maintenance of the differentiated phenotype but for cell proliferation as well.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Castrillo, J L -- Theill, L E -- Karin, M -- DK38527/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1991 Jul 12;253(5016):197-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, School of Medicine, University of California, San Diego, La Jolla 92093.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1677216" target="_blank"〉PubMed〈/a〉

    Description: The natriuretic peptides are hormones that can stimulate natriuretic, diuretic, and vasorelaxant activity in vivo, presumably through the activation of two known cell surface receptor guanylyl cyclases (ANPR-A and ANPR-B). Although atrial natriuretic peptide (ANP) and, to a lesser extent, brain natriuretic peptide (BNP) are efficient activators of the ANPR-A guanylyl cyclase, neither hormone can significantly stimulate ANPR-B. A member of this hormone family, C-type natriuretic peptide (CNP), potently and selectively activated the human ANPR-B guanylyl cyclase. CNP does not increase guanosine 3',5'-monophosphate accumulation in cells expressing human ANPR-A. The affinity of CNP for ANPR-B is 50- or 500-fold higher than ANP or BNP, respectively. This ligand-receptor pair may be involved in the regulation of fluid homeostasis by the central nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koller, K J -- Lowe, D G -- Bennett, G L -- Minamino, N -- Kangawa, K -- Matsuo, H -- Goeddel, D V -- New York, N.Y. -- Science. 1991 Apr 5;252(5002):120-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Genentech, Inc., South San Francisco 94080.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1672777" target="_blank"〉PubMed〈/a〉

    Description: The protein tyrosine kinase activity of the cellular Src protein is negatively regulated by phosphorylation at tyrosine residue 527 (Tyr527). It has not been established whether this regulatory modification of Src is mediated by autophosphorylation or by another cellular protein kinase. The phosphorylation of a modified form of c-Src that lacks kinase activity was examined in mouse cells that do not express endogenous Src (because of the targeted disruption of both src alleles). Phosphorylation of the inactive form of Src on Tyr527 occurred to a similar extent in cells lacking endogenous Src as it did in cells expressing Src. Therefore, Tyr527 phosphorylation, and thus negative control of Src kinase activity, is mediated by another cellular protein tyrosine kinase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thomas, J E -- Soriano, P -- Brugge, J S -- New York, N.Y. -- Science. 1991 Oct 25;254(5031):568-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Microbiology, University of Pennsylvania, School of Medicine, Philadelphia 19104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1719633" target="_blank"〉PubMed〈/a〉

    Description: The N-methyl-D-aspartate (NMDA) receptor, a subtype of glutamate receptors, plays a key role in synaptic plasticity in the nervous system. After NMDA receptor activation, calcium entry into the postsynaptic neuron is a critical initial event. However, the subsequent mechanisms by which the NMDA receptor signal is processed are incompletely understood. Stimulation of cultured rat hippocampal cells with glutamate resulted in the rapid and transient tyrosine phosphorylation of a 39-kilodalton protein (p39). Tyrosine phosphorylation of p39 was triggered by the NMDA receptor and required an influx of Ca2+ from the extracellular medium. Because p39 was found to be highly related or identical to the microtubule-associated protein 2 kinase, the NMDA receptor signal may be processed by a sequential activation of protein kinases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bading, H -- Greenberg, M E -- CA 43855/CA/NCI NIH HHS/ -- NS 28829/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1991 Aug 23;253(5022):912-4.〈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/1715095" target="_blank"〉PubMed〈/a〉

    Description: Movement of neutrophils from the bloodstream to inflamed tissue depends on the activation of both the neutrophil and the endothelial cell. Endothelial cells lining the postcapillary venule respond to proinflammatory mediators by expressing adhesion molecules and synthesizing a variety of neutrophil-activating factors. Endothelial cell production of a 77-amino acid variant of interleukin-8 (IL-8) was found to be a requirement for the invasion of neutrophils through a vessel wall model. IL-8 secreted by cytokine- or lipopolysaccharide-stimulated endothelial cells induced the rapid shedding of neutrophil lectin adhesion molecule-1, the up-regulation of leukocyte beta 2 integrins, and the attachment and transmigration of the neutrophils. Thus, endogenous endothelial IL-8 regulates transvenular traffic during acute inflammatory responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huber, A R -- Kunkel, S L -- Todd, R F 3rd -- Weiss, S J -- CA 39064/CA/NCI NIH HHS/ -- HL 28024/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1991 Oct 4;254(5028):99-102.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, University of Michigan, Ann Arbor 48109.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1718038" target="_blank"〉PubMed〈/a〉

    Description: Specific messenger RNAs (mRNAs) can be sequestered within distinct cellular locations, but little is known about how this is accomplished. The participation of the three major cellular filaments in the localization of actin mRNA was studied in chicken embryo fibroblasts. Movement of actin mRNA to the cell periphery and maintenance of that regionalization required intact microfilaments (composed of actin) but not microtubules or intermediate filaments. The results presented here suggest that actin-binding proteins may participate in mRNA sorting.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sundell, C L -- Singer, R H -- HD18066/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1991 Sep 13;253(5025):1275-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, University of Massachusetts Medical School, Worcester 01655.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1891715" target="_blank"〉PubMed〈/a〉

    Description: Use of primary culture cells has been limited by the inability to purify most types of cells, particularly cells from early developmental stages. In whole animal cell sorting (WACS), live cells derived from animals harboring a lacZ transgene are purified according to their level of beta-galactosidase expression with a fluorogenic beta-galactosidase substrate and fluorescence-activated cell sorting. With WACS, incipient posterior compartment cells that express the engrailed gene were purified from early Drosophila embryos. Neuronal precursor cells were also purified, and they differentiated into neurons with high efficiency in culture. Because there are many lacZ strains, it may be possible to purify most types of Drosophila cells. The same approach is also applicable to other organisms for which germ-line transformation is possible.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Krasnow, M A -- Cumberledge, S -- Manning, G -- Herzenberg, L A -- Nolan, G P -- CA09151/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 Jan 4;251(4989):81-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1898782" target="_blank"〉PubMed〈/a〉

    Description: T lymphocytes undergo selection events not only in the thymus, but also after they leave the thymus and reside in the periphery. Peripheral selection was found to be dependent on T cell receptor (TCR)-ligand interactions but to differ from thymic selection with regard to specificity and mechanism. Unlike thymic selection, peripheral selection required binding of antigen to the TCR, and it induced expansion of T cell clones. Tolerance to self antigens that are restricted to the periphery occurred through the elimination of self-reactive T cells and by the clonal anergy, which was associated with down-regulation of the alpha beta TCR and CD8.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rocha, B -- von Boehmer, H -- New York, N.Y. -- Science. 1991 Mar 8;251(4998):1225-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Unite INSERM U-25 CNRS UA-122, Hopital Necker, Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1900951" target="_blank"〉PubMed〈/a〉

    Description: A mutated form of the platelet-derived growth factor (PDGF) beta receptor lacking most of its cytoplasmic domain was tested for its ability to block wild-type PDGF receptor function. PDGF induced the formation of complexes consisting of wild-type and truncated receptors. Such complexes were defective in autophosphorylation. When truncated receptors were expressed in excess compared to wild-type receptors, stimulation by PDGF of receptor autophosphorylation, association of phosphatidylinositol-3 kinase with the receptor, and calcium mobilization were blocked. Thus, a truncated receptor can inactivate wild-type receptor function by forming ligand-dependent receptor complexes (probably heterodimers) that are incapable of mediating the early steps of signal transduction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ueno, H -- Colbert, H -- Escobedo, J A -- Williams, L T -- P01 HL-43821/HL/NHLBI NIH HHS/ -- R01 HL-32898/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1991 May 10;252(5007):844-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉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/1851331" target="_blank"〉PubMed〈/a〉

    Description: An inducible rabbit endothelial adhesion molecule that is selective for mononuclear leukocytes has been identified. This adhesion protein was expressed on the surface of activated cultured endothelium in two forms, 118 and 98 kilodaltons, the amino-terminal sequence of each being highly homologous to human VCAM-1. In dietary hypercholesterolemic and Watanabe heritable hyperlipidemic rabbit models of atherosclerosis, this adhesion molecule was found to be expressed in a localized fashion by aortic endothelium that overlies early foam cell lesions. This lesion-localized expression suggests a potential endothelium-dependent mechanism for mononuclear leukocyte recruitment during atherogenesis and may provide a molecular marker for early atherosclerosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cybulsky, M I -- Gimbrone, M A Jr -- P01-HL-36028/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1991 Feb 15;251(4995):788-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Brigham and Women's Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1990440" target="_blank"〉PubMed〈/a〉

    Description: The development and stability of synaptic connections in the nervous system are influenced by the pattern of electrical activity and the competitive interaction between the adjacent nerve terminals. To investigate this influence, a culture system of nerve and muscle cells has been developed in which a single embryonic muscle cell is coinnervated by two spinal neurons. The effect of electrical activity on the synaptic efficacy was examined after repetitive electrical stimulation was applied to one or both neurons. Brief tetanic stimulation of one neuron resulted in immediate functional suppression of the synapse made by the unstimulated neuron innervating the same muscle cell. This heterosynaptic suppression was largely absent when the tetanic stimulation was applied concurrently to both neurons. This result demonstrates that activity-dependent synaptic competition can be studied in vitro at a cellular level.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lo, Y J -- Poo, M M -- NS 22764/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1991 Nov 15;254(5034):1019-22.〈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/1658939" target="_blank"〉PubMed〈/a〉

    Description: The Rel-associated protein pp40 is functionally related to I kappa B, an inhibitor of the transcription factor NF-kappa B. Purified pp40 inhibits the DNA binding activity of the NF-kappa B protein complex (p50:p65 heterodimers), p50:c-Rel heteromers, and c-Rel homodimers. The sequence of the complementary DNA encoding pp40 revealed similarity to the gene encoding MAD-3, a protein with mammalian I kappa B-like activity. Protein sequencing of I kappa B purified from rabbit lung confirmed that MAD-3 encodes a protein similar to I kappa B. The sequence similarity between MAD-3 and pp40 includes a casein kinase II and consensus tyrosine phosphorylation site, as well as five repeats of a sequence found in the human erythrocyte protein ankyrin. These results suggest that rel-related transcription factors, which are capable of cytosolic to nuclear translocation, may be held in the cytosol by interaction with related cytoplasmic anchor molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, N -- Ghosh, S -- Simmons, D L -- Tempst, P -- Liou, H C -- Baltimore, D -- Bose, H R Jr -- CA09583/CA/NCI NIH HHS/ -- CA2616/CA/NCI NIH HHS/ -- CA33192/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 Sep 13;253(5025):1268-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, University of Texas, Austin 78712.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1891714" target="_blank"〉PubMed〈/a〉

    Description: During development of the nervous system, neurons in many regions are overproduced by proliferation, after which the excess cells are eliminated by cell death. The survival of only a proportion of neurons during normal development is thought to be regulated by the limited availability of neurotrophic agents. One such putative trophic agent is ciliary neurotrophic factor (CNTF), a polypeptide that promotes the survival of ciliary, sensory, and sympathetic neurons in vitro. In contrast to the results of in vitro studies, however, the daily treatment of chick embryos in vivo with purified human recombinant CNTF failed to rescue any of these cell populations from cell death, whereas CNTF did promote the in vivo survival of spinal motoneurons.

    Description: CD45 is a member of a family of membrane proteins that possess phosphotyrosine phosphatase activity, and is the source of much of the tyrosine phosphatase activity in lymphocytes. In view of its enzymatic activity and high copy number, it seems likely that CD45 functions in transmembrane signal transduction by lymphocyte receptors that are coupled to activation of tyrosine kinases. The B cell antigen receptor was found to transduce a Ca(2+)-mobilizing signal only if cells expressed CD45. Also, both membrane immunoglobulin M (mIgM) and CD45 were lost from the surface of cells treated with antibody to CD45, suggesting a physical interaction between these proteins. Finally, CD45 dephosphorylated a complex of mIg-associated proteins that appears to function in signal transduction by the antigen receptor. These data indicate that CD45 occurs as a component of a complex of proteins associated with the antigen receptor, and that CD45 may regulate signal transduction by modulating the phosphorylation state of the antigen receptor subunits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Justement, L B -- Campbell, K S -- Chien, N C -- Cambier, J C -- AI20519/AI/NIAID NIH HHS/ -- AI21768/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1991 Jun 28;252(5014):1839-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, National Jewish Center for Immunology and Respiratory Medicine, Denver, CO.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1648262" target="_blank"〉PubMed〈/a〉

    Description: Malignant gliomas are the most common malignant brain tumors and are almost always fatal. A thymidine kinase-negative mutant of herpes simplex virus-1 (dlsptk) that is attenuated for neurovirulence was tested as a possible treatment for gliomas. In cell culture, dlsptk killed two long-term human glioma lines and three short-term human glioma cell populations. In nude mice with implanted subcutaneous and subrenal U87 human gliomas, intraneoplastic inoculation of dlsptk caused growth inhibition. In nude mice with intracranial U87 gliomas, intraneoplastic inoculation of dlsptk prolonged survival. Genetically engineered viruses such as dlsptk merit further evaluation as novel antineoplastic agents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martuza, R L -- Malick, A -- Markert, J M -- Ruffner, K L -- Coen, D M -- NS24279/NS/NINDS NIH HHS/ -- R01-AI26126/AI/NIAID NIH HHS/ -- SO7RRO5381/RR/NCRR NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1991 May 10;252(5007):854-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Neurogenetics Laboratory, Harvard Medical School, Massachusetts General Hospital-East, Charlestown 02129.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1851332" target="_blank"〉PubMed〈/a〉

    Description: Long-term depression (LTD) in the intact cerebellum is a decrease in the efficacy of the parallel fiber-Purkinje neuron synapse induced by coactivation of climbing fiber and parallel fiber inputs. In cultured Purkinje neurons, a similar depression can be induced by iontophoretic glutamate pulses and Purkinje neuron depolarization. This form of LTD is expressed as a depression of alpha-amino-3-hydroxy-5-methyl-4- isoxazole-propionic acid (AMPA)-mediated current, and its induction is dependent on activation of metabotropic quisqualate receptors. The effect of inhibitors of protein kinase C (PKC) on LTD induction was studied. Inhibitors of PKC blocked LTD induction, while phorbol-12,13-diacetate (PDA), a PKC activator, mimicked LTD. These results suggest that PKC activation is necessary for the induction of cerebellar LTD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Linden, D J -- Connor, J A -- New York, N.Y. -- Science. 1991 Dec 13;254(5038):1656-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurosciences, Roche Institute of Molecular Biology, Roche Research Center, Nutley, NJ 07110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1721243" target="_blank"〉PubMed〈/a〉

    Description: The endogenous mos proto-oncogene product (Mos) is required for meiotic maturation. In Xenopus oocytes, the ras oncogene product (Ras) can induce meiotic maturation and high levels of M-phase--promoting factor (MPF) independent of endogenous Mos, indicating that a parallel pathway to metaphase exists. In addition, Ras, like Mos and cytostatic factor, can arrest Xenopus embryonic cell cleavage in mitosis and maintain high levels of MPF. Thus, in the Xenopus oocyte and embryo systems Ras functions in the M phase of the cell cycle. The embryonic cleavage arrest assay is a rapid and sensitive test for Ras function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Daar, I -- Nebreda, A R -- Yew, N -- Sass, P -- Paules, R -- Santos, E -- Wigler, M -- Vande Woude, G F -- N01-CO-74101/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 Jul 5;253(5015):74-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉ABL-Basic Research Program, National Cancer Institute-Frederick Cancer Research and Development Center, MD 21701.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1829549" target="_blank"〉PubMed〈/a〉

    Description: As well as being activated or rendered unresponsive, mature T lymphocytes can be deleted, depending on the signals received by the cell. Deletion by programmed cell death (apoptosis) is triggered if a T cell that has received a signal through its T cell receptor complex also receives a signal through the alpha 3 domain of its class I major histocompatibility complex (MHC) molecule. Such a signal can be delivered by a CD8 molecule, which recognizes the alpha 3 domain, or by an antibody to this domain. Precursors of both cytotoxic T lymphocytes (CTL's) and T helper cells are sensitive to this signal but become resistant at some point before completing differentiation into functioning CTL's or T helper cells. Because CTL's carry CD8, they can induce cell death in T cells that recognize them. This pathway may be important in both removal of autoreactive T cells and immunoregulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sambhara, S R -- Miller, R G -- New York, N.Y. -- Science. 1991 Jun 7;252(5011):1424-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ontario Cancer Institute, University of Toronto, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1828618" target="_blank"〉PubMed〈/a〉

    Description: In the mammalian central nervous system, receptors for excitatory amino acid neurotransmitters such as the alpha-amino-3-hydroxy-5-methyl-4- isoxazolepropionic acid (AMPA)-kainate receptor mediate a large fraction of excitatory transmission. Currents induced by activation of the AMPA-kainate receptor were potentiated by agents that specifically stimulate adenosine 3',5'-monophosphate (cAMP)-dependent protein kinase A (PKA) activity or were supported by intracellular application of the catalytic subunit of PKA by itself or in combination with cAMP. Furthermore, depression of these currents by a competitive inhibitor of PKA indicates that AMPA-kainate receptors are regulated by endogenous PKA. Endogenous protein phosphatases also regulate these receptors because an inhibitor of cellular phosphates enhanced kainate currents. Modulation of PKA and phosphatases may regulate the function of these receptors and thus contribute to synaptic plasticity in hippocampal neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, L Y -- Salter, M W -- MacDonald, J F -- New York, N.Y. -- Science. 1991 Sep 6;253(5024):1132-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, University of Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1653455" target="_blank"〉PubMed〈/a〉

    Description: Receptor channels activated by glutamate, an excitatory neurotransmitter in the mammalian brain, are involved in processes such as long-term potentiation and excitotoxicity. Studies of glutamate receptor channels expressed in cultured hippocampal pyramidal neurons reveal that these channels are subject to neuromodulatory regulation through the adenylate cyclase cascade. The whole-cell current response to glutamate and kainate [a non-NMDA (N-methyl-D-aspartate) receptor agonist] was enhanced by forskolin, an activator of adenylate cyclase. Single-channel analysis revealed that an adenosine 3',5'-monophosphate-dependent protein kinase (PKA) increases the opening frequency and the mean open time of the non-NMDA-type glutamate receptor channels. Analysis of synaptic events indicated that forskolin, acting through PKA, increased the amplitude and decay time of spontaneous excitatory postsynaptic currents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Greengard, P -- Jen, J -- Nairn, A C -- Stevens, C F -- New York, N.Y. -- Science. 1991 Sep 6;253(5024):1135-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular and Cellular Neuroscience, Rockefeller University, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1716001" target="_blank"〉PubMed〈/a〉

    Description: A 200-fold inhibition in the titer of infectious vesicular stomatitis virus (VSV) was produced in cultures of Ly cells treated with 30 reference units of interferon per milliliter. Virus particle production, as measured by VSV particle-associated transcriptase, or nucleocapsid protein was inhibited by a maximum of tenfold. The glycoprotein and membrane protein content was reduced in VSV derived from interferon-treated cells. Thus interferon-treated cells may have produced VSV particles with low infectivity, which may be related to the reduced amount of glycoprotein incorporated into such particles. These findings resemble those reported in interferon-treated cells infected with murine leukemia viruses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maheshwari, R K -- Jay, F T -- Friedman, R M -- New York, N.Y. -- Science. 1980 Feb 1;207(4430):540-1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6243416" target="_blank"〉PubMed〈/a〉

    Description: The life-span in vitro and other proliferative characteristics of a strain of endothelial cells cloned from the aorta of a fetal calf were examined. Cultures of these cells had a replicative life-span of approximately 80 cumulative population doublings. Growth rates in the logarithmic phase and plateau densities decreased as the cumulative population-doubling level increased. After approximately 65 percent of the life-span of a culture was completed, the percentage of cells that incorporated [3H]thymidine during a 24-hour labeling period began to decrease rapidly. The cells expressed factor VIII antigen and their intercellular borders were stainable with silver nitrate throughout the life-span of each culture. Average cellular attachment size increased more than threefold between cumulative population-doubling levels 41 and 80. The facility with which cloned strains of endothelial cells can be isolated should encourage further exploitation of this important cell culture model.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mueller, S N -- Rosen, E M -- Levine, E M -- New York, N.Y. -- Science. 1980 Feb 22;207(4433):889-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7355268" target="_blank"〉PubMed〈/a〉

    Description: The simian guartan malaria parasite Plasmodium inui (OS strain) was cultured in a continuous flow system with rhesus monkey erythrocytes and RPMI 1640nmedium supplemented with Hepes buffer and rhesus serum. Over a 10-week period, the growth of the parasite permitted a 61,000-fold cumulative dilution of the original inoculum. After 5 weeks in culture, the parasites were still infective to the monkey Saimiri sciureus and to Anopheles freeborni mosquitoes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nguyen-Dinh, P -- Campbell, C C -- Collins, W E -- New York, N.Y. -- Science. 1980 Sep 12;209(4462):1249-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6773146" target="_blank"〉PubMed〈/a〉

    Description: Hybrid cells formed between human lymphocytes and mouse myeloma cells produce human immunoglobulin in culture. Stable antibody-producing cell lines can be isolated after multiple cycles of low-density passage, cloning, and continued selection for immunoglobulin production. The origin and characteristics of a hybrid of human and mouse cells is described. This hybrid produces high concentrations (8.3 micrograms per milliliter) of human immunoglobulin M reactive with the terminal disaccharide of the Forssman glycolipid. These findings point to the potential use of human-mouse hybrid cells as a source of human monoclonal antibodies for therapeutic and diagnostic purposes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nowinski, R -- Berglund, C -- Lane, J -- Lostrom, M -- Bernstein, I -- Young, W -- Hakomori, S I -- Hill, L -- Cooney, M -- New York, N.Y. -- Science. 1980 Oct 31;210(4469):537-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7423202" target="_blank"〉PubMed〈/a〉

    Description: Mutants of animal viruses can be isolated in bacteria by recombinant DNA methods. Since no viral functions are required for propagation of recombinants in bacteria, viral mutants with lethal changes in cis- or trans-acting elements can be isolated, as well as partially or conditionally defective mutants. In the cases of viruses with small DNA genomes, such as the tumorigenic simian virus 40 (SV40), the entire viral DNA can be inserted into the bacterial plasmid pBR322 and cloned in Escherichia coli. Recombinant plasmids with a single copy of SV40 DNA cause morphological transformation of mouse cells in culture with the same efficiency as SV40 DNA isolated from virus-infected monkey cells, but the recombinant DNA is noninfectious and replicates poorly in permissive cells. However, SV40 DNA excised from the plasmid replicates as well as authentic viral DNA and is fully infectious. SV40 mutants with small deletions or base substitutions have been isolated by in vitro site-specific or random local mutagenesis of recombinant DNA followed by cloning in E. coli. Many of the mutants thus isolated are defective in specific viral functions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peden, K W -- Pipas, J M -- Pearson-White, S -- Nathans, D -- New York, N.Y. -- Science. 1980 Sep 19;209(4463):1392-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6251547" target="_blank"〉PubMed〈/a〉

    Description: The activities of cyclic nucleotide phosphohydrolase, an enzyme marker for oligodendrocytes, and glutamine synthetase, an enzyme marker for astrocytes, were studied at early (21 to 26) and late (82 to 88) cell passages. The activity of cyclic nucleotide phosphohydrolase was markedly high and that of glutamine synthetase was low in the early passages, but this relation was reversed in the late passages. These findings suggest a "transdifferentiation" of C6 glial cells with passage in culture.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parker, K K -- Norenberg, M D -- Vernadakis, A -- New York, N.Y. -- Science. 1980 Apr 11;208(4440):179-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6102413" target="_blank"〉PubMed〈/a〉

    Description: Monolayer cultures of rat aorta smooth muscle cells synthesized the anti-aggregatory substance prostacyclin via the cyclooxygenase pathway from 14C-labeled arachidonic acid. The product was identified both by bioassay and by mass spectrometry. Labeled cells produced prostacyclin only when exposed to the initiator thrombin: treatment with therapeutic concentrations of aspirin (0.2 millimolar) for 30 minutes completely destroyed the cells' ability to synthesize prostacyclin. Prostacyclin synthesis from exogenous arachidonic acid recovered fully within 1 to 2 hours by a cycloheximide-sensitive process. Thrombin responsivness, which was permanently impaired in confluent nondividing cultures, recovered substantially and within 24 hours only when cells were stimulated to divide by subculturing. These results indicate that resting vascular cells can rapidly synthesize new cyclooxygenase, but that aspirin destroys additional components of the prostacyclin system which can only be replaced during cell division.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whiting, J -- Salata, K -- Bailey, J M -- New York, N.Y. -- Science. 1980 Nov 7;210(4470):663-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6776627" target="_blank"〉PubMed〈/a〉

    Description: The genotoxicity of the antihypertensive agents hydralazine and dihydralazine was tested in mammalian cells and bacteria. Both drugs elicited DNA repair in rat hepatocyte primary cultures. In the Ames test, both with and without an S-9 fraction, hydralazine was mutagenic in strains TA100 and TA1537, whereas dihydralazine was weakly mutagenic in strain TA1537. These findings support the observation that hydralazine is carcinogenic in mice. The carcinogenicity of many chemicals results from interaction with DNA. Since these studies demonstrate that hydralazine and dihydralazine damage DNA in mammalian cells, these drugs should be viewed as potential human carcinogens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, G M -- Mazue, G -- McQueen, C A -- Shimada, T -- N 01-CP-55705/CP/NCI NIH HHS/ -- New York, N.Y. -- Science. 1980 Oct 17;210(4467):329-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7423193" target="_blank"〉PubMed〈/a〉

    Description: A strain of type 2 human rotavirus (Wa) was grown to relatively high titer through 14 passages in primary cultures of African green monkey kidney (AGMK) cells. This passage series was initiated with virus that had been passaged 11 times serially in newborn gnotobiotic piglets. In contrast, virus present in the stool of patient Wa as well as virus from the first, second, or third passage in piglets could not be propagated successfully in African green monkey kidney cells. Prior to each passage in cell culture, the virus was treated with trypsin and the inoculated cultures were centrifuged at low speed. Cultivation of a type 2 human rotavirus should aid attempts to characterize this virus and to develop a means of immunoprophylaxis for a serious diarrheal disease of human infants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wyatt, R G -- James, W D -- Bohl, E H -- Theil, K W -- Saif, L J -- Kalica, A R -- Greenberg, H B -- Kapikian, A Z -- Chanock, R M -- New York, N.Y. -- Science. 1980 Jan 11;207(4427):189-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6243190" target="_blank"〉PubMed〈/a〉

    Description: Human malignant cancer tumors grafted into nude mice produce tumors containing both human cancer cells and the host's stromal cells. After short-term propagation of these tumors in vitro, the murine mesenchymal cells appear transformed and are tumorigenic in nude mice. However, established human cancer cell lines fail to similarly after adjacent murine stromal cells when used to produce tumors in nude mice. These experiments suggest that cancer cells may recruit normal cells to become malignant, qualifying the view of the clonal (unicellular) origin of cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldenberg, D M -- Pavia, R A -- 1R01 CA17198/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Apr 3;212(4490):65-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209521" target="_blank"〉PubMed〈/a〉

    Description: Voltage clamp studies of macrophages from cultures of mouse spleen macrophages produced N-shaped steady-state current-voltage curves containing a region of negative slope resistance. Some macrophages exhibit two stable states of membrane potential, having current-voltage relationships that cross the voltage axis at three points. Outward currents that turn on at voltages of +15 millivolts or greater were noted in several cells. The addition of barium chloride to the bathing medium abolished the negative slope resistance and reduced the inward currents in response to hyperpolarizing voltage steps. These data provide direct evidence that macrophages exhibit at least tow different voltage-dependent conductances and demonstrate that voltage clamp techniques can be useful in studying the membrane properties of leukocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gallin, E K -- New York, N.Y. -- Science. 1981 Oct 23;214(4519):458-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7291986" target="_blank"〉PubMed〈/a〉

Inhibition is reversible, and potency increases with chain length of the alcohol. The results suggest that delta receptors are considerably more sensitive to alcohols than mu receptors.

    Description: Stage-specific changes in histone synthesis during sea urchin development reflect the expression of different sets of genes. The three kinds of blastomeres formed at the 16-cell stage are the earliest "determined" cells and fall into three distinct size classes. At this stage that cells synthesize only "early" histones. Such blastomeres can survive and divide in culture after being separated from the embryo, whether or not they are permitted to aggregate. With or without reaggregation, cultured progeny cells of each type of isolated blastomere perform the same changeover of histone synthesis as takes place in the intact embryo, that is, they begin spontaneously to synthesize a new set, the "late" histone variants. Normal contact relations among cells of the embryo are, therefore, not required for this programmed change in gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arceci, R J -- Gross, P R -- New York, N.Y. -- Science. 1980 Aug 1;209(4456):607-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7394523" target="_blank"〉PubMed〈/a〉

    Description: The cellular mechanisms underlying picrotoxin-induced convulsive activity were studied by using mouse spinal neurons growing in tissue culture. Picrotoxin-induced convulsive activity in most but not all of the cells studied. The activity could be inverted by polarizing to positive potentials and eliminated either by decreasing the ratio of calcium to magnesium or by applying tetrodotoxin. When applied locally to individual cells, picrotoxin lowered spike threshold and induced spontaneous firing in some but not all cells tested. The results suggest that picrotoxin-induced convulsive activity involves rapidly summating synaptic activity which may be evoked by high-frequency repetitive firing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barker, J L -- MacDonald, J F -- New York, N.Y. -- Science. 1980 May 30;208(4447):1054-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7375918" target="_blank"〉PubMed〈/a〉

    Description: The endothelia of microvessels isolated from mouse brain by mechanical means are rich in gamma-glutamyl transpeptidase; however, the enzyme often disappears when the cells migrate or proliferate from the microvessel isolates. In an endothelial cell line derived from similar isolates and negative for gamma-glutamyl transpeptidase, the enzyme could be induced in the endothelial cells when they were cocultured with glial cells. Thus there may be a requirement for continuous induction of gamma-glutamyl transpeptidase in brain microvessels by adjacent glial cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉DeBault, L E -- Cancilla, P A -- New York, N.Y. -- Science. 1980 Feb 8;207(4431):653-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6101511" target="_blank"〉PubMed〈/a〉

    Description: A covalent conjugate of an alpha-amanitin azo derivative and a monoclonal immunoglobulin G to the Thy 1.2 antigen on murine T lymphocytes was synthesized. The conjugate was 375- to 750-fold more inhibitory to murine T lymphoma S49.1 cells than the unconjugated derivative. At 0.7 X 10(-7) to 1.5 X 10(-7) M and at 4 X 10(-7) M amanitin equivalents, the conjugate inhibited protein synthesis in S49.1 cells by 50 percent and 80 to 96 percent, respectively. At these concentrations, mutant Thy l-deficient S49 cells and other murine lymphoma lacking Thy l altogether or carrying Thy 1.1 antigens were unaffected. This result demonstrated the potential for targeting amanitin to specific cell types.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, M T -- Preston, J F 3rd -- R01 CA 19043/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Sep 18;213(4514):1385-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6115471" target="_blank"〉PubMed〈/a〉

    Description: When bound to cell surfaces, certain lectins such as concanavalin A induce a drop in the average diffusion coefficients (D) of a number of cell surface molecules. To find whether such anchorage modulation occurs naturally, D of surface antigens on different cell and tissue types were measured by fluorescence photobleaching recovery. Values for cells of the same tissue origin under different conditions of growth and association - in tissues, in small aggregates, and as isolated cells - varied by less than twofold when polyspecific monovalent antibodies to cell surface antigens were used, a range much less than the sixfold decrease in D observed after lectin-induced anchorage modulation. Thus, if reversible modulation of the diffusion rate is used naturally as a means of cell signaling, it must involve only a few kinds of surface receptors not detected by the antibodies used in this study. In certain tissues, however, a significant proportion of cells showed no apparent receptor mobility. This "all or none" modulation of lateral diffusion may reflect relatively long-lasting alterations in the states of a single cell type or differentiation among the cells of the particular tissue.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gall, W E -- Edelman, G M -- AI-09273/AI/NIAID NIH HHS/ -- AI-11378/AI/NIAID NIH HHS/ -- AM-04256/AM/NIADDK NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1981 Aug 21;213(4510):903-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7196087" target="_blank"〉PubMed〈/a〉

    Description: Somatomedin-C stimulates somatostatin release to a maximum of 390 percent of basal release during short-term (20-minute) incubation of rat hypothalamus. It has no effect on basal or stimulated growth hormone release from primary cultures of rat adenohypophyseal cells during a 4-hour incubation, but inhibits stimulated release by more that 90 percent after 24 hours. These findings suggest that somatomedin-C participates in the growth hormone negative feedback loop with an immediate effect on hypothalamic somatostatin and a delayed effect on the anterior pituitary.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berelowitz, M -- Szabo, M -- Frohman, L A -- Firestone, S -- Chu, L -- Hintz, R L -- AM 18722/AM/NIADDK NIH HHS/ -- AM 24085/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Jun 12;212(4500):1279-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6262917" target="_blank"〉PubMed〈/a〉

    Description: Sympathetic neurons from newborn rats, cultured for 1 month or longer in the virtual absence of nonneuronal cells, were capable of regenerating neurites after neuritotomy. Regeneration occurred even after nerve growth factor was withdrawn from the cultures, although it was much less extensive and appeared limited to a few days following neuritotomy. Even after 29 days of nerve growth factor deprivation, reintroduction of the protein prompted a resumption of neurite growth. Possible roles of both nerve growth factor-independent and -dependent components in adult nerve regeneration are discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Campenot, R B -- NS15559/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 30;214(4520):579-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7292000" target="_blank"〉PubMed〈/a〉

    Description: Trypsin-dissociated atrial cardiocytes from adult rats were exposed to [3H]thymidine for sequential 24-hour periods from day 2 to day 12 of culture. On day 3 and each day thereafter, cells were prepared for ultrastructural radioautography and examined with an electron microscope. Maximal incorporation occurred on day 5, when 63 percent of the cardiocytes were labeled. Mitotic activity was never present in more than 0.5 percent of the cardiocytes examined. Incorporation of [3H]thymidine and mitosis occurred only in immature cardiocytes characterized by subsarcolemmal primary filaments and Z bands with or without specific granules; more mature cardiocytes were never labeled.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cantin, M -- Ballak, M -- Beuzeron-Mangina, J -- Anand-Srivastava, M B -- Tautu, C -- New York, N.Y. -- Science. 1981 Oct 30;214(4520):569-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7291996" target="_blank"〉PubMed〈/a〉

    Description: The growth in vitro of human breast cancer cells, line MCF-7, was inhibited by a daily supplement of L-arginine (1 milligram per milliliter). Arginine acted synergistically with dibutyryl adenosine 3',5'-monophosphate (cyclic AMP) (10(-6) molar) to enhance the growth inhibitory effect: the cell replication ceased completely within 2 days after treatment. The growth arrest accompanied a change in cell morphology and was preceded by increases in the cellular concentration of cyclic AMP, adenylate cyclase, and type II cyclic AMP-dependent protein kinase activities as well as a decrease of estrogen binding activity. The results suggest that growth of human breast cancer cells is subject to cyclic AMP-mediated regulation and that arginine may play a specific role in this process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cho-Chung, Y S -- Clair, T -- Bodwin, J S -- Berghoffer, B -- New York, N.Y. -- Science. 1981 Oct 2;214(4516):77-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6269181" target="_blank"〉PubMed〈/a〉

    Description: A clone of L1210 mouse leukemia cells selected for resistance to both the antiviral and anticellular properties of mouse interferon were essentially devoid of fatty acid cyclooxygenase activity. Experiments in which broken cell preparations were mixed or the two cell types were cultivated together failed to indicate the presence of a diffusible enzyme inhibitor. Fatty acid lipoxygenase activity of similar magnitude was detectable in both cell types. A selective impairment of fatty acid cyclooxygenase in interferon-resistant cells is consistent with recently described data suggesting that this enzyme may play a crucial role in mediating the antiviral and anticellular effects of interferon.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chandrabose, K A -- Cuatrecasas, P -- Pottathil, R -- Lang, D J -- New York, N.Y. -- Science. 1981 Apr 17;212(4492):329-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6163214" target="_blank"〉PubMed〈/a〉

    Description: This study suggests one mechanism by which alveolar macrophages accumulate in the lung in pulmonary emphysema: elastin fragments generated at the diseased sites are potent chemoattractants for monocytes, the precursors of the macrophages. The most chemotactic elastin fragments have a molecular weight between 10,000 and 50,000 and are active at concentrations as low as 3 nanograms per milliliter. By comparison, elastin fragments with higher molecular weights and desmosines are active at concentrations greater than 0.3 microgram per milliliter. In addition, preincubation of monocytes with the 10,000- to 50,000-dalton elastin impairs the ability of the cells to migrate toward elastin fragments but not toward activated serum. Fragments of tropoelastin are not chemotactic for monocytes. Because elastin, but not tropoelastin, contains lysyl-derived cross-links, these structures may be the active chemotactic site on the elastin fragments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hunninghake, G W -- Davidson, J M -- Rennard, S -- Szapiel, S -- Gadek, J E -- Crystal, R G -- New York, N.Y. -- Science. 1981 May 22;212(4497):925-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233186" target="_blank"〉PubMed〈/a〉

    Description: Removal of the posterior pituitary from anesthetized male rats results in a prompt and significant increase in circulating prolactin that is reversed by the injection of dopamine. Posterior pituitary extracts, which contain high concentrations of endogenous dopamine, inhibit prolactin secretion from isolated anterior pituitary cells. This inhibition is prevented by incubation of the cells with the dopamine receptor antagonist (+)-butaclamol. The data show that posterior pituitary dopamine reaches the anterior pituitary via the short hypophysial portal vessels and participates in the regulation of prolactin secretion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peters, L L -- Hoefer, M T -- Ben-Jonathan, N -- HD 14348/HD/NICHD NIH HHS/ -- NS-13234/NS/NINDS NIH HHS/ -- NS-219/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Aug 7;213(4508):659-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7256264" target="_blank"〉PubMed〈/a〉

    Description: Immunocytochemistry shows that early during phagocytosis of zymosan, adenosine 3',5'-monophosphate (cyclic AMP) appears on the cell surface before the phagosome is internalized. The appearance of cyclic AMP on the cell surface is coincident with that of granule products and regulatory subunit of type I cyclic AMP-dependent protein kinase. Guanosine 3',5'-monophosphate is not associated with the initiation site of phagocytosis, but is observed throughout the granular cytoplasmic region. This sharply localized accumulation of cyclic AMP may serve as a signal for the initiation of phagocytosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pryzwansky, K B -- Steiner, A L -- Spitznagel, J K -- Kapoor, C L -- 02430-22/PHS HHS/ -- AM17438/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Jan 23;211(4480):407-10.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6261328" target="_blank"〉PubMed〈/a〉

    Description: Various lectins were found to induce tyrosine aminotransferase in H-35 rat hepatoma cells grown in monolayer culture. Wheat germ agglutinin gave a maximal induction of tyrosine aminotransferase 6 hours after its addition. The induction time course was similar to that elicited by insulin. Fourteen micrograms of wheat germ agglutinin per milliliter gave half-maximal enzyme induction and 50 micrograms per milliliter gave the maximal response. The induction of tyrosine aminotransferase by wheat germ agglutinin was additive with the induction by either dexamethasone or dibutyryl adenosine 3',5'-monophosphate, but was not additive with the tyrosine amino transferase induction by insulin. Wheat germ agglutinin also mimicked insulin in the inhibition of cellular protein degradation in the absence of serum. The insulin-like effects of lectins should be considered in lectin-mediated manipulations such as agglutination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, J D -- Liu, A Y -- AM20274/AM/NIADDK NIH HHS/ -- GM 07258/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1981 Nov 13;214(4522):799-800.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6117128" target="_blank"〉PubMed〈/a〉

    Description: The molecularly cloned, long terminal repeat (LTR) of the Moloney sarcoma virus (M-MSV) provirus has been covalently linked to c-mos, the cellular homolog of the M-MSV-specific sequence, v-mos. These newly constructed clones lack any M-MSV-derived sequences other than the LTR, but in DNA transfection assays they transform cells as efficiently as cloned subgenomic M-MSV fragments containing both v-mos and LTR. Cells transformed by LTR:c-mos hybrid molecules contain additional copies of mos DNA, and several size classes of polyadenylated RNA's with sequence homology to mos. The activation of the transforming potential of c-mos by the proviral LTR suggests a model whereby LTR-like elements could activate other normal cell sequences with oncogenic potential.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blair, D G -- Oskarsson, M -- Wood, T G -- McClements, W L -- Fischinger, P J -- Vande Woude, G G -- New York, N.Y. -- Science. 1981 May 22;212(4497):941-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233190" target="_blank"〉PubMed〈/a〉

    Description: Epinephrine and isoproterenol provoke primary chick myoblasts to initiate precocious cell fusion. Both the rise in intracellular adenosine 3' ,5-monophosphate (cyclic AMP) and cell fusion generated by these effectors are prevented by propranolol, which is a specific blocker of the beta-adrenergic receptor. Propranolol has no effect either on the precocious cell fusion provoked by prostaglandin E or on cell fusion in control cultures. The results support the idea that a rise in cyclic AMP is the critical intracellular change responsible for initiating events that culminate in myoblast differentiation 4 to 5 hours later. They also indicate that the culminate in myoblast differentiation 4 to 5 hours later. They also indicate that the hormone responsible for the positive regulation of myoblast differentiation in vitro is not acting through the beta-adrenergic receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Curtis, D H -- Zalin, R J -- New York, N.Y. -- Science. 1981 Dec 18;214(4527):1355-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6274017" target="_blank"〉PubMed〈/a〉

Inhibition was nearly 100-fold less, however, when DNA synthesis was measured by incorporation of phosphorus-32-labeled phosphate or by DNA fluorescence.

    Description: Dynamic contractions of bile canaliculi were observed in groups of cultured hepatocytes by time-lapse cinephotomicrography during the early stages of monolayer formation.

    Description: Fibroblasts contain a specific internalization pathway that carries hormones as well as some proteins and viruses from the cell surface to the cell interior. Initially, the ligands bind to mobile receptors that are randomly distributed on the cell surface. Next the ligand-receptor complexes are trapped and concentrated in specialized regions of the membrane termed bristle-coated pits. From the pit a smooth-walled vesicle containing the ligand forms and carries the ligand to the cell interior. Because of its role in receptor-mediated endocytosis, this vesicle has been termed a "receptosome."〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pastan, I H -- Willingham, M C -- New York, N.Y. -- Science. 1981 Oct 30;214(4520):504-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6170111" target="_blank"〉PubMed〈/a〉

    Description: Bovine brain gangliosides were applied to primary and established neuronal cultures to examine the role of gangliosides in neuronal development. Media containing gangliosides enhanced the degree of axonal elongation exhibited by sensory ganglia neurons and increased the length and number of Neuro-2a neuroblastoma cell processes. Ganglioside-supplemented media caused a twofold increase in ornithine decarboxylase activity in both culture systems. These experiments suggest that gangliosides function as acceptor molecules for growth-promoting substances in embryonic and tumor-derived neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roisen, F J -- Bartfeld, H -- Nagele, R -- Yorke, G -- NS 11299/NS/NINDS NIH HHS/ -- NS 11605/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 30;214(4520):577-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7291999" target="_blank"〉PubMed〈/a〉

    Description: In alcoholic liver injury, necrosis is involved in the progression from benign fatty liver to alcoholic hepatitis and cirrhosis. However, there is no practical model of alcohol-dependent liver cell necrosis. The calcium-dependent killing of cultured rat hepatocytes by two different membrane-active hepatotoxins, galactosamine and phalloidin, is potentiated by ethyl alcohol. This indicates that some general physical effect of alcohol on cellular membranes renders cells susceptible to otherwise nonlethal injuries. The in vitro model described in this report may thus be used to search for a general mechanism underlying alcohol-related tissue injury.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schanne, F A -- Zucker, A H -- Farber, J L -- Rubin, E -- AA 03442/AA/NIAAA NIH HHS/ -- AM 19154/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Apr 17;212(4492):338-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209533" target="_blank"〉PubMed〈/a〉

    Description: Fusion of fresh lymphocytes from a Bloom syndrome (BS) patient with those of normal subjects or a BS heterozygote resulted in complete normalization of the frequency of sister chromatid exchanges in the chromosomes of BS cells. This normalization took place by the first mitosis in hybrid cells. In contrast, cultivation of BS lymphocytes with those of normal subjects or the BS heterozygote had no effect on sister chromatid exchanges. The cell fusion experiments suggest that the normalization on the sister chromatid exchanges. The cell fusion experiments suggest that the normalization of the sister chromatid exchange frequencies in BS cells can be achieved by factors conserved in the cells of various mammalian species. These findings are compatible with the concept that BS is a recessive genetic mutation at regulatory levels of the DNA repair function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shiraishi, Y -- Matsui, S -- Sandberg, A A -- CA-14555/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 May 15;212(4496):820-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7221565" target="_blank"〉PubMed〈/a〉

    Description: Freshly isolated hepatocytes from phenobarbital-treated rats were incubated in the presence or absence of extracellular calcium with three differently acting liver cell toxins, namely carbon tetrachloride, bromobenzene, and ethylmethanesulfonate. In the absence of extracellular calcium these three compounds were far more toxic to the cells than in its presence. This result is inconsistent with the hypothesis that an influx of extracellular calcium is required as the final step in toxic liver cell injury.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, M T -- Thor, H -- Orrenius, S -- New York, N.Y. -- Science. 1981 Sep 11;213(4513):1257-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7268433" target="_blank"〉PubMed〈/a〉

The viruses were neutralized by serum and spinal fluid from these patients. Although most of the population have antibody to these virus isolates, multiple sclerosis patients have slightly higher concentrations of serum antibody than controls. The results suggest that coronaviruses should be considered as one additional virus with a potential implication in the etiology of multiple sclerosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burks, J S -- DeVald, B L -- Jankovsky, L D -- Gerdes, J C -- New York, N.Y. -- Science. 1980 Aug 22;209(4459):933-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7403860" target="_blank"〉PubMed〈/a〉

    Description: Stereoisomers of the barbiturate anesthetic pentobarbital were applied to mouse spinal neurons growing in tissue culture. Intracellular recordings of neuronal membrane properties revealed that the (+) and (-) isomers caused direct changes in membrane potential and conductance on some but not all of the cells tested. The action of the (+) isomer was predominantly excitatory, whereas the (-) isomer produced predominantly inhibitory responses. The (-) isomer was considerably more effective in potentiating inhibitory responses to the transmitter gamma-aminobutyric acid. The results show that pentobarbital has multiple effects on neuronal excitability and demonstrate the presence of stereospecific sites of barbiturate action on central neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, L Y -- Barker, J L -- New York, N.Y. -- Science. 1980 Jan 11;207(4427):195-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7350656" target="_blank"〉PubMed〈/a〉

The resemblance is so close that in certain instances the tumor stem cells can join with their embryonic counterparts and develop into a completely normal mouse. The availability of stem cell lines isolated from mouse teratocarcinomas has made possible a number of new biochemical, immunological, and genetic approahes to the study of early mammalian development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martin, G R -- New York, N.Y. -- Science. 1980 Aug 15;209(4458):768-76.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6250214" target="_blank"〉PubMed〈/a〉
