    Description: Promonocytic (U1) and T lymphocytic (ACH-2) cell lines chronically infected with human immunodeficiency virus type 1 (HIV-1) constitutively express low levels of virus, but expression can be induced by phorbol esters and cytokines. Whereas ACH-2 cells produce infectious virions, U1 cells produce defective, noninfectious particles. Although 3'-azido-3'-deoxythimidine (AZT) prevented acute HIV infection of susceptible cells, it did not prevent the induction of HIV expression in the infected cell lines. In contrast, interferon alpha (IFN-alpha) inhibited the release of reverse transcriptase and viral antigens into the culture supernatant after phorbol ester stimulation of both cell lines. Further, IFN-alpha suppressed the production or release (or both) of whole HIV virions, but had no effect on the amount of cell-associated viral proteins. Also, after phorbol ester stimulation of ACH-2 cells, IFN-alpha reduced the number of infectious viral particles secreted into the culture supernatant, but had no effect on the infectivity of cell-associated virus. These findings lend support to the combined use of antiviral agents that have action at both the early (AZT) and the late (IFN-alpha) stages of HIV replication.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Poli, G -- Orenstein, J M -- Kinter, A -- Folks, T M -- Fauci, A S -- New York, N.Y. -- Science. 1989 May 5;244(4904):575-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunoregulation, National Institute of Allergy and Infectious Diseases, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2470148" target="_blank"〉PubMed〈/a〉

    Description: GABAA (gamma-aminobutyric acid A)-benzodiazepine receptors expressed in mammalian cells and assembled from one of three different alpha subunit variants (alpha 1, alpha 2, or alpha 3) in combination with a beta 1 and a gamma 2 subunit display the pharmacological properties of either type I or type II receptor subtypes. These receptors contain high-affinity binding sites for benzodiazepines. However, CL 218 872, 2-oxoquazepam, and methyl beta-carboline-3-carboxylate (beta-CCM) show a temperature-modulated selectivity for alpha 1 subunit-containing receptors. There were no significant differences in the binding of clonazepam, diazepam, Ro 15-1788, or dimethoxy-4-ethyl-beta-carboline-3-carboxylate (DMCM) to all three recombinant receptors. Receptors containing the alpha 3 subunit show greater GABA potentiation of benzodiazepine binding than receptors containing the alpha 1 or alpha 2 subunit, indicating that there are subtypes within the type II class. Thus, diversity in benzodiazepine pharmacology is generated by heterogeneity of the alpha subunit of the GABAA receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pritchett, D B -- Luddens, H -- Seeburg, P H -- New York, N.Y. -- Science. 1989 Sep 22;245(4924):1389-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Neuroendocrinology, Zentrum fur Molekulare Biologie, Universitat Heidelberg, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2551039" target="_blank"〉PubMed〈/a〉

    Description: Specialized regions of muscle fibers may result from differential gene expression within a single fiber. In order to investigate the range of action of individual nuclei in multinucleated myotubes, C2 myoblasts were transfected to obtain stable cell lines that express a reporter protein that is targeted to the nucleus. Hybrid myotubes were then formed containing one or a few transfected nuclei as well as a large number of nuclei from the parental strain. In order to determine how far the products of a single nucleus extend, transfected nuclei were labeled with [3H]thymidine before fusion and the myotubes were stained to identify the reporter protein. In such myotubes the fusion protein was not confined to its nucleus of origin, but was restricted to nearby nuclei.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ralston, E -- Hall, Z W -- NS 20107/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 2;244(4908):1066-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, School of Medicine, University of California, San Francisco 94143-0444.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2543074" target="_blank"〉PubMed〈/a〉

    Description: Expression of the c-myc oncogene is deregulated in a variety of malignancies. Rearrangement and mutation of the c-myc locus is a characteristic feature of human Burkitt's lymphoma. Whether deregulation is solely a result of mutation of c-myc or whether it is influenced by the transformed B cell context has not been determined. A translocated and mutated allele of c-myc was stably transfected into fibroblasts. The rearranged allele was expressed indistinguishably from a normal c-myc gene: it had serum-regulated expression, was transcribed with normal promoter preference, and was strongly attenuated. Thus mutations by themselves are insufficient to deregulate c-myc transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Richman, A -- Hayday, A -- 40364/PHS HHS/ -- GM 07499/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Oct 27;246(4929):494-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biology Department, Yale University, New Haven, CT 06511.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2683072" target="_blank"〉PubMed〈/a〉

    Description: A procedure has been developed for introducing exogenous DNA into mouse eggs by injection of chromosome fragments. Chromosome fragments were dissected from human metaphase spreads and microinjected into the pronuclei of fertilized mouse eggs. Many of the injected eggs subsequently exhibited normal pre- and postimplantation development. Embryos obtained from eggs injected with centromeric fragments retained human centromeric DNA as demonstrated by in situ hybridization analysis. From eggs injected with noncentromeric fragments, a mouse was obtained whose tail tissue exhibited the presence of human DNA. This procedure should facilitate incorporation of very large (more than 10 megabases) DNA fragments into cells and embryos without the need for cloned sequences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Richa, J -- Lo, C W -- New York, N.Y. -- Science. 1989 Jul 14;245(4914):175-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biology Department, University of Pennsylvania, Philadelphia 19104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2749254" target="_blank"〉PubMed〈/a〉

    Description: Adipsin is a serine protease that is secreted by adipocytes into the bloodstream; it is deficient in several animal models of obesity, representing a striking example of defective gene expression in this disorder. Recombinant mouse adipsin was purified and its biochemical and enzymatic properties were studied in order to elucidate the function of this protein. Activated adipsin has little or no proteolytic activity toward most substrates but has the same activity as human complement factor D, cleaving complement factor B when it is complexed with activated complement component C3. Like authentic factor D, adipsin can activate the alternative pathway of complement, resulting in red blood cell lysis. Decreased (58 to 80 percent) complement factor D activity, relative to lean controls, was observed as a common feature of several experimental models of obesity, including the ob/ob, db/db, and monosodium glutamate (MSG)-injected mouse and the fa/fa rat. These results suggest that adipsin and the alternative pathway of complement may play an unexpected but important role in the regulation of systemic energy balance in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosen, B S -- Cook, K S -- Yaglom, J -- Groves, D L -- Volanakis, J E -- Damm, D -- White, T -- Spiegelman, B M -- DK31403/DK/NIDDK NIH HHS/ -- DK34605/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 23;244(4911):1483-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana-Farber Cancer Institute, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2734615" target="_blank"〉PubMed〈/a〉

    Description: Salmonella bacteria are capable of entering (invading) and multiplying within eukaryotic cells. Stable adherence to and invasion of epithelial cells by S. choleraesuis and S. typhimurium were found to require de novo synthesis of several new bacterial proteins. This inducible event appears to be a coordinately regulated system dependent on trypsin- and neuraminidase-sensitive structures present on the epithelial cell surface.

    Description: Ornithine decarboxylase (ODC) was converted from a protein with a short intracellular half-life in mammalian cells to a stable protein by truncating 37 residues at its carboxyl terminus. Cells expressing wild-type protein lost ODC activity with a half-life of approximately 1 hour. Cells expressing the truncated protein, however, retained full activity for at least 4 hours. Pulse-chase experiments in which immunoprecipitation and gel electrophoresis were used confirmed the stabilizing effect of the truncation. Thus, a carboxyl-terminal domain is responsible for the rapid intracellular degradation of murine ODC.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ghoda, L -- van Daalen Wetters, T -- Macrae, M -- Ascherman, D -- Coffino, P -- CA 09043/CA/NCI NIH HHS/ -- CA 29048/CA/NCI NIH HHS/ -- CA 47721/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Mar 17;243(4897):1493-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2928784" target="_blank"〉PubMed〈/a〉

    Description: Three cellular homologs of the v-erbA oncogene were previously identified in the rat; two of them encode high affinity receptors for the thyroid hormone triiodothyronine (T3). A rat complementary DNA clone encoding a T3 receptor form of the ErbA protein, called r-ErbA beta-2, was isolated. The r-ErbA beta-2 protein differs at its amino terminus from the previously described rat protein encoded by c-erbA beta and referred to as r-ErbA beta-1. Unlike the other members of the c-erbA proto-oncogene family, which have a wide tissue distribution, r-erbA beta-2 appears to be expressed only in the anterior pituitary gland. In addition, thyroid hormone downregulates r-erbA beta-2 messenger RNA but not r-erbA beta-1 messenger RNA in a pituitary tumor-derived cell line. The presence of a pituitary-specific form of the thyroid hormone receptor that may be selectively regulated by thyroid hormone could be important for the differential regulation of gene expression by T3 in the pituitary gland.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hodin, R A -- Lazar, M A -- Wintman, B I -- Darling, D S -- Koenig, R J -- Larsen, P R -- Moore, D D -- Chin, W W -- New York, N.Y. -- Science. 1989 Apr 7;244(4900):76-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Brigham and Women's Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2539642" target="_blank"〉PubMed〈/a〉

    Description: Two distinct CD3-associated T cell receptors (TCR alpha beta and TCR gamma delta) are expressed in a mutually exclusive fashion on separate subsets of T lymphocytes. While the specificity of the TCR alpha beta repertoire for major histocompatibility complex (MHC) antigens is well established, the diversity of expressed gamma delta receptors and the ligands they recognize are less well understood. An alloreactive CD3+CD4-CD8- T cell line specific for murine class II MHC (Ia) antigens encoded in the I-E subregion of the H-2 gene complex was identified, and the primary structure of its gamma delta receptor heterodimer was characterized. In contrast to a TCR alpha beta-expressing alloreactive T cell line selected for similar specificity, the TCR gamma delta line displayed broad cross-reactivity for multiple distinct I-E-encoded allogeneic Ia molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matis, L A -- Fry, A M -- Cron, R Q -- Cotterman, M M -- Dick, R F -- Bluestone, J A -- 5-T32AI07090-10/AI/NIAID NIH HHS/ -- CA-14599-15/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1989 Aug 18;245(4919):746-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biochemistry and Biophysics, Food and Drug Administration, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2528206" target="_blank"〉PubMed〈/a〉

    Description: Guanosine 5'-triphosphate (GTP)-binding proteins have been implicated in the transport of newly synthesized proteins along the secretory pathway of yeast and mammalian cells. Early vesicle fusion events that follow receptor-mediated endocytosis as measured by three in vitro assays were blocked by guanosine 5'-O-(3-thiotriphosphate) and aluminum fluoride. The effect was specific for guanosine nucleotides and depended on the presence of cytosolic factors. Thus, GTP-binding proteins may also have a role in the transport of molecules along the endocytic pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mayorga, L S -- Diaz, R -- Stahl, P D -- AI 20015/AI/NIAID NIH HHS/ -- CA 12858/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 23;244(4911):1475-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology and Physiology, Washington University School of Medicine, St. Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2499930" target="_blank"〉PubMed〈/a〉

    Description: Methods for the design and synthesis of ligands intended to be specific for a metal ion have been a recent chemical development. This article describes how this process can be inverted so that the specifics of the coordination environment around the metal ion can be used as a template in large-scale ligand synthesis. The synthesis of macrobicyclic ligands for ferric ion has been accomplished by using active esters of catechol ligands in which catecholate coordination to iron is a prelude to the organic chemical reactions that link the coordination subunits together into one ligand system surrounding a central metal ion coordination site. The lanthanide(III) ions, which are among the most labile metal ions known, have coordination numbers of 8 or higher, and thus their encapsulation into a macrobicyclic structure is a challenging problem. Lanthanide amine complexes have been used as metal templates in the synthesis of such macrobicyclic lanthanide complexes. There is evidence that such a complex is inert to exchange in aqueous solution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McMurry, T J -- Raymond, K N -- Smith, P H -- New York, N.Y. -- Science. 1989 May 26;244(4907):938-43.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Radiation Oncology Branch, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2658057" target="_blank"〉PubMed〈/a〉

It is composed of an IgE-binding alpha subunit, a beta subunit, and two gamma subunits. The human alpha subunit was expressed on transfected cells in the presence of rat beta and gamma subunits or in the presence of the gamma subunit alone. The IgE binding properties of the expressed human alpha were characteristic of receptors on normal human cells. These results now permit a systematic analysis of human IgE binding and a search for therapeutically useful inhibitors of that binding.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, L -- Blank, U -- Metzger, H -- Kinet, J P -- New York, N.Y. -- Science. 1989 Apr 21;244(4902):334-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section on Chemical Immunology, National Institute of Arthritis and Musculoskeletal and Skin Diseases, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2523561" target="_blank"〉PubMed〈/a〉

    Description: In vivo protein-DNA interactions at the developmentally regulated enhancer of the mouse muscle creatine kinase (MCK) gene were examined by a newly developed polymerase chain reaction (PCR) footprinting procedure. This ligation mediated, single-sided PCR technique permits the exponential amplification of an entire sequence ladder. Several footprints were detected in terminally differentiated muscle cells where the MCK gene is actively transcribed. None were observed in myogenic cells prior to differentiation or in nonmuscle cells. Two footprints appear to correspond to sites that can bind the myogenic regulator MyoD1 in vitro, whereas two others represent muscle specific use of apparently general factors. Because MyoD1 is synthesized by undifferentiated myoblasts, these data imply that additional regulatory mechanisms must restrict the interaction between this protein and its target site prior to differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mueller, P R -- Wold, B -- GM35526/GM/NIGMS NIH HHS/ -- RR07003/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1989 Nov 10;246(4931):780-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, California Institute of Technology, Pasadena 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2814500" target="_blank"〉PubMed〈/a〉

    Description: A strategy was devised for identifying regions of the mouse genome that are transcriptionally active in a temporally and spatially restricted manner during development. The approach is based on the introduction into embryonic stem cells of two types of lacZ reporter constructs that can be activated by flanking mouse genomic sequences. Embryonic stem cells containing the lacZ constructs were used to produce chimaeric mice. Developmental regulation of lacZ expression occurred at a high frequency. Molecular cloning of the flanking endogenous genes and introduction of these potential insertional mutations into the mouse germ line should provide an efficient means of identifying and mutating novel genes important for the control of mammalian development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gossler, A -- Joyner, A L -- Rossant, J -- Skarnes, W C -- New York, N.Y. -- Science. 1989 Apr 28;244(4903):463-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mount Sinai Hospital Research Institute, Division of Molecular and Developmental Biology, Toronto, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2497519" target="_blank"〉PubMed〈/a〉

    Description: Mechanistic and synthetic studies in organometallic chemistry have provided considerable insight into olefin metathesis and Ziegler-Natta polymerization. New homogeneous olefin metathesis catalysts based on high oxidation state transition metals have opened new opportunities in polymer synthesis by providing unprecedented control in ring-opening polymerization of cyclic alkenes. The recent development of living coordinative polymerization systems has led to the preparation of a number of new, interesting materials, including block copolymers, conducting polymers or precursors, and ionophoric polymeric substrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grubbs, R H -- Tumas, W -- New York, N.Y. -- Science. 1989 Feb 17;243(4893):907-15.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉California Institute of Technology, Pasadena 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2645643" target="_blank"〉PubMed〈/a〉

    Description: Granulocyte and natural killer (NK) cell Fc receptors for immunoglobulin G (CD16) differ in only a few amino acids, yet have phosphatidylinositol glycan (PIG) or polypeptide membrane anchors, respectively. Mutagenesis shows that anchoring is regulated by a serine residue near the PIG anchor attachment site in the extracellular domain. The NK cell isoform was not expressed on the surface of COS cells unless cotransfected with a subunit that was expressed in NK cells and that was identical to the gamma subunit of the high affinity IgE Fc receptor (Fc epsilon RI). However, the CD16 sequence and not expression of the gamma subunit is dominant in regulating PIG reanchoring.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hibbs, M L -- Selvaraj, P -- Carpen, O -- Springer, T A -- Kuster, H -- Jouvin, M H -- Kinet, J P -- New York, N.Y. -- Science. 1989 Dec 22;246(4937):1608-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2531918" target="_blank"〉PubMed〈/a〉

    Description: Cell fusion (syncytium formation) is a major cytopathic effect of infection by human immunodeficiency virus (HIV) and may also represent an important mechanism of CD4+ T-cell depletion in individuals infected with HIV. Syncytium formation requires the interaction of CD4 on the surface of uninfected cells with HIV envelope glycoprotein gp120 expressed on HIV-infected cells. However, several observations suggest that molecules other than CD4 play a role in HIV-induced cell fusion. The leukocyte adhesion receptor LFA-1 is involved in a broad range of leukocyte interactions mediated by diverse receptor-ligand systems including CD4-class II major histocompatibility complex (MHC) molecules. Possible mimicry of class II MHC molecules by gp120 in its interaction with CD4 prompted an examination of the role of LFA-1 in HIV-induced cell fusion. A monoclonal antibody against LFA-1 completely inhibited HIV-induced syncytium formation. The antibody did not block binding of gp120 to CD4. This demonstrates that a molecule other than CD4 is also involved in cell fusion mediated by HIV.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hildreth, J E -- Orentas, R J -- 5T32CA09243/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 2;244(4908):1075-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology and Molecular Sciences, Johns Hopkins University School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2543075" target="_blank"〉PubMed〈/a〉

    Description: Joining of V-, D-, and J-region gene segments during DNA rearrangements within all antigen receptor genes involves recognition of the same highly conserved heptamernonamer sequences flanking each segment. In order to investigate the possibility that recognition of these conserved sequences may sometimes permit intergenic joining of segments among different antigen receptor genes, DNA of normal human lymphoid tissues was examined by polymerase chain reaction amplification for the presence of chimeric gamma-delta T cell receptor gene rearrangements. These studies detected V gamma-(D delta)-J delta and V delta-(D delta)-J gamma rearrangements in thymus, peripheral blood, and tonsil. Analysis of thymus RNA indicated that many of these rearrangements are expressed as V gamma-(D delta)-J delta-C delta and V delta-(D delta)-J gamma-C gamma transcripts. Most transcripts (19 of 20 complementary DNA clones studied) are appropriately spliced and show correct open translational reading frames across the V-(D)-J junctions. Thus, chimeric antigen receptor genes are generated in a subset of normal lymphoid cells, probably as a result of chromosomal translocations, and such genes may possibly contribute to increased diversity within the antigen receptor repertoire.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tycko, B -- Palmer, J D -- Sklar, J -- CA38621/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1989 Sep 15;245(4923):1242-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2551037" target="_blank"〉PubMed〈/a〉

    Description: Fos and Jun form a heterodimeric complex that associates with the nucleotide sequence motif known as the AP-1 binding site. Although this complex has been proposed to function as a transcriptional regulator in neurons, no specific target gene has yet been identified. Proenkephalin mRNA increased in the hippocampus during seizure just after an increase in c-fos and c-jun expression was detected. Fos-Jun complexes bound specifically to a regulatory sequence in the 5' control region of the proenkephalin gene. Furthermore, c-fos and c-jun stimulated transcription from this control region synergistically in transactivation assays. These data suggest that the proenkephalin gene may be a physiological target for Fos and Jun in the hippocampus and indicate that these proto-oncogene transcription factors may play a role in neuronal responses to stimulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sonnenberg, J L -- Rauscher, F J 3rd -- Morgan, J I -- Curran, T -- New York, N.Y. -- Science. 1989 Dec 22;246(4937):1622-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Oncology, 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/2512642" target="_blank"〉PubMed〈/a〉

    Description: Amyloid deposition in senile plaques and the cerebral vasculature is a marker of Alzheimer's disease. Whether amyloid itself contributes to the neurodegenerative process or is simply a by-product of that process is unknown. Pheochromocytoma (PC12) and fibroblast (NIH 3T3) cell lines were transfected with portions of the gene for the human amyloid precursor protein. Stable PC12 cell transfectants expressing a specific amyloid-containing fragment of the precursor protein gradually degenerated when induced to differentiate into neuronal cells with nerve growth factor.

    Description: The linker histones (H1, H5, H1 degrees) are involved in the condensation of chromatin into the 30-nanometer fiber. This supranucleosome organization correlates with the resting state of chromatin, and it is therefore possible that the linker histones play an active role in the control of chromatin activity. The effect of H5 has been directly determined by expression of an inducible transfected H5 gene in rat sarcoma cells, which do not produce H5. Transfection resulted in the reversible inhibition of DNA replication and arrest of cells in G1, at which time H5 concentrations approached that of terminally differentiated avian erythrocytes. The arrest of proliferation was accompanied by specific changes in gene expression probably related to the cell cycle block. The selectivity of these effects suggest that H5 plays an active role in the control of DNA replication and cell proliferation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sun, J M -- Wiaderkiewicz, R -- Ruiz-Carrillo, A -- New York, N.Y. -- Science. 1989 Jul 7;245(4913):68-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Research Center, Laval University School of Medicine, L'Hotel-Dieu du Quebec, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2740916" target="_blank"〉PubMed〈/a〉

    Description: Despite widespread belief that violence begets violence, methodological problems substantially restrict knowledge of the long-term consequences of childhood victimization. Empirical evidence for this cycle of violence has been examined. Findings from a cohort study show that being abused or neglected as a child increases one's risk for delinquency, adult criminal behavior, and violent criminal behavior. However, the majority of abused and neglected children do not become delinquent, criminal, or violent. Caveats in interpreting these findings and their implications are discussed in this article.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Widom, C S -- S07 RR07031/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1989 Apr 14;244(4901):160-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Criminal Justice, Indiana University, Bloomington 47405.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2704995" target="_blank"〉PubMed〈/a〉

    Description: The transcription factor NF-kappaB modulates apoptotic responses induced by genotoxic stress. We show that NF-kappaB essential modulator (NEMO), the regulatory subunit of IkappaB kinase (IKK) (which phosphorylates the NF-kappaB inhibitor IkappaB), associates with activated ataxia telangiectasia mutated (ATM) after the induction of DNA double-strand breaks. ATM phosphorylates serine-85 of NEMO to promote its ubiquitin-dependent nuclear export. ATM is also exported in a NEMO-dependent manner to the cytoplasm, where it associates with and causes the activation of IKK in a manner dependent on another IKK regulator, a protein rich in glutamate, leucine, lysine, and serine (ELKS). Thus, regulated nuclear shuttling of NEMO links two signaling kinases, ATM and IKK, to activate NF-kappaB by genotoxic signals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Zhao-Hui -- Shi, Yuling -- Tibbetts, Randal S -- Miyamoto, Shigeki -- R01-CA77474/CA/NCI NIH HHS/ -- R01-CA81065/CA/NCI NIH HHS/ -- R01-GM067868/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 24;311(5764):1141-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Wisconsin-Madison, 301 SMI, 1300 University Avenue, Madison, WI 53706, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16497931" target="_blank"〉PubMed〈/a〉

    Description: We describe the use of gold nanoparticle-oligonucleotide complexes as intracellular gene regulation agents for the control of protein expression in cells. These oligonucleotide-modified nanoparticles have affinity constants for complementary nucleic acids that are higher than their unmodified oligonucleotide counterparts, are less susceptible to degradation by nuclease activity, exhibit greater than 99% cellular uptake, can introduce oligonucleotides at a higher effective concentration than conventional transfection agents, and are nontoxic to the cells under the conditions studied. By chemically tailoring the density of DNA bound to the surface of gold nanoparticles, we demonstrated a tunable gene knockdown.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosi, Nathaniel L -- Giljohann, David A -- Thaxton, C Shad -- Lytton-Jean, Abigail K R -- Han, Min Su -- Mirkin, Chad A -- New York, N.Y. -- Science. 2006 May 19;312(5776):1027-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and International Institute for Nanotechnology, Northwestern University, 2145 Sheridan Road, Evanston, IL 60208-3113 USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16709779" target="_blank"〉PubMed〈/a〉

    Description: Chromosomal integration enables human immunodeficiency virus (HIV) to establish a permanent reservoir that can be therapeutically suppressed but not eradicated. Participation of cellular proteins in this obligate replication step is poorly understood. We used intensified RNA interference and dominant-negative protein approaches to show that the cellular transcriptional coactivator lens epithelium-derived growth factor (LEDGF)/p75 (p75) is an essential HIV integration cofactor. The mechanism requires both linkages of a molecular tether that p75 forms between integrase and chromatin. Fractionally minute levels of endogenous p75 are sufficient to enable integration, showing that cellular factors that engage HIV after entry may elude identification in less intensive knockdowns. Perturbing the p75-integrase interaction may have therapeutic potential.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Llano, Manuel -- Saenz, Dyana T -- Meehan, Anne -- Wongthida, Phonphimon -- Peretz, Mary -- Walker, William H -- Teo, Wulin -- Poeschla, Eric M -- New York, N.Y. -- Science. 2006 Oct 20;314(5798):461-4.

    Description: The surface potential of biological membranes varies according to their lipid composition. We devised genetically encoded probes to assess surface potential in intact cells. These probes revealed marked, localized alterations in the charge of the inner surface of the plasma membrane of macrophages during the course of phagocytosis. Hydrolysis of phosphoinositides and displacement of phosphatidylserine accounted for the change in surface potential at the phagosomal cup. Signaling molecules such as K-Ras, Rac1, and c-Src that are targeted to the membrane by electrostatic interactions were rapidly released from membrane subdomains where the surface charge was altered by lipid remodeling during phagocytosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yeung, Tony -- Terebiznik, Mauricio -- Yu, Liming -- Silvius, John -- Abidi, Wasif M -- Philips, Mark -- Levine, Tim -- Kapus, Andras -- Grinstein, Sergio -- New York, N.Y. -- Science. 2006 Jul 21;313(5785):347-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Cell Biology, Hepatology, and Nutrition Department, Hospital for Sick Children, Toronto, Ontario M5G 1X8, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16857939" target="_blank"〉PubMed〈/a〉
