    ACh receptor-rich membrane domains organized in fibroblasts by recombinant 43-kildalton protein (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1991-02-01
    Beschreibung: Neurotransmitter receptors are generally clustered in the postsynaptic membrane. The mechanism of clustering was analyzed with fibroblast cell lines that were stably transfected with the four subunits for fetal (alpha, beta, gamma, delta) or adult (alpha, beta, epsilon, delta) type mouse muscle nicotinic acetylcholine receptors (AChRs). Immunofluorescent staining indicated that AChRs were dispersed on the surface of these cells. When transiently transfected with an expression construct encoding a 43-kilodalton protein that is normally concentrated under the postsynaptic membrane, AChRs expressed in these cells became aggregated in large cell-surface clusters, colocalized with the 43-kilodalton protein. This suggests that 43-kilodalton protein can induce AChR clustering and that cluster induction involves direct contact between AChR and 43-kilodalton protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Phillips, W D -- Kopta, C -- Blount, P -- Gardner, P D -- Steinbach, J H -- Merlie, J P -- R01 NS022356/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1991 Feb 1;251(4993):568-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, 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/1703661" target="_blank"〉PubMed〈/a〉

    A secreted PTEN phosphatase that enters cells to alter signaling and survival (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-06-08
    Beschreibung: Phosphatase and tensin homolog on chromosome ten (PTEN) is a tumor suppressor and an antagonist of the phosphoinositide-3 kinase (PI3K) pathway. We identified a 576-amino acid translational variant of PTEN, termed PTEN-Long, that arises from an alternative translation start site 519 base pairs upstream of the ATG initiation sequence, adding 173 N-terminal amino acids to the normal PTEN open reading frame. PTEN-Long is a membrane-permeable lipid phosphatase that is secreted from cells and can enter other cells. As an exogenous agent, PTEN-Long antagonized PI3K signaling and induced tumor cell death in vitro and in vivo. By providing a means to restore a functional tumor-suppressor protein to tumor cells, PTEN-Long may have therapeutic uses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3935617/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3935617/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hopkins, Benjamin D -- Fine, Barry -- Steinbach, Nicole -- Dendy, Meaghan -- Rapp, Zachary -- Shaw, Jacquelyn -- Pappas, Kyrie -- Yu, Jennifer S -- Hodakoski, Cindy -- Mense, Sarah -- Klein, Joshua -- Pegno, Sarah -- Sulis, Maria-Luisa -- Goldstein, Hannah -- Amendolara, Benjamin -- Lei, Liang -- Maurer, Matthew -- Bruce, Jeffrey -- Canoll, Peter -- Hibshoosh, Hanina -- Parsons, Ramon -- 2T32 CA09503/CA/NCI NIH HHS/ -- CA082783/CA/NCI NIH HHS/ -- CA097403/CA/NCI NIH HHS/ -- P01 CA097403/CA/NCI NIH HHS/ -- R01 CA082783/CA/NCI NIH HHS/ -- R01 CA155117/CA/NCI NIH HHS/ -- R01 NS066955/NS/NINDS NIH HHS/ -- R01 NS073610/NS/NINDS NIH HHS/ -- R01NS066955/NS/NINDS NIH HHS/ -- T32 CA009503/CA/NCI NIH HHS/ -- T32 GM008224/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 Jul 26;341(6144):399-402. doi: 10.1126/science.1234907.

    A natural polymorphism alters odour and DEET sensitivity in an insect odorant receptor (2011)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2011-09-23
    Beschreibung: Blood-feeding insects such as mosquitoes are efficient vectors of human infectious diseases because they are strongly attracted by body heat, carbon dioxide and odours produced by their vertebrate hosts. Insect repellents containing DEET (N,N-diethyl-meta-toluamide) are highly effective, but the mechanism by which this chemical wards off biting insects remains controversial despite decades of investigation. DEET seems to act both at close range as a contact chemorepellent, by affecting insect gustatory receptors, and at long range, by affecting the olfactory system. Two opposing mechanisms for the observed behavioural effects of DEET in the gas phase have been proposed: that DEET interferes with the olfactory system to block host odour recognition and that DEET actively repels insects by activating olfactory neurons that elicit avoidance behaviour. Here we show that DEET functions as a modulator of the odour-gated ion channel formed by the insect odorant receptor complex. The functional insect odorant receptor complex consists of a common co-receptor, ORCO (ref. 15) (formerly called OR83B; ref. 16), and one or more variable odorant receptor subunits that confer odour selectivity. DEET acts on this complex to potentiate or inhibit odour-evoked activity or to inhibit odour-evoked suppression of spontaneous activity. This modulation depends on the specific odorant receptor and the concentration and identity of the odour ligand. We identify a single amino-acid polymorphism in the second transmembrane domain of receptor OR59B in a Drosophila melanogaster strain from Brazil that renders OR59B insensitive to inhibition by the odour ligand and modulation by DEET. Our data indicate that natural variation can modify the sensitivity of an odour-specific insect odorant receptor to odour ligands and DEET. Furthermore, they support the hypothesis that DEET acts as a molecular 'confusant' that scrambles the insect odour code, and provide a compelling explanation for the broad-spectrum efficacy of DEET against multiple insect species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3203342/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3203342/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pellegrino, Maurizio -- Steinbach, Nicole -- Stensmyr, Marcus C -- Hansson, Bill S -- Vosshall, Leslie B -- R01 DC008600/DC/NIDCD NIH HHS/ -- R01 DC008600-02/DC/NIDCD NIH HHS/ -- R01 DC008600-02S1/DC/NIDCD NIH HHS/ -- R01 DC008600-03/DC/NIDCD NIH HHS/ -- R01 DC008600-03S1/DC/NIDCD NIH HHS/ -- R01 DC008600-03S2/DC/NIDCD NIH HHS/ -- R01 DC008600-04/DC/NIDCD NIH HHS/ -- R01 DC008600-05/DC/NIDCD NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Sep 21;478(7370):511-4. doi: 10.1038/nature10438.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Neurogenetics and Behaviour, The Rockefeller University, 1230 York Avenue, Box 63, New York, New York 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21937991" target="_blank"〉PubMed〈/a〉

    Mammalian expression of infrared fluorescent proteins engineered from a bacterial phytochrome (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2009-05-09
    Beschreibung: Visibly fluorescent proteins (FPs) from jellyfish and corals have revolutionized many areas of molecular and cell biology, but the use of FPs in intact animals, such as mice, has been handicapped by poor penetration of excitation light. We now show that a bacteriophytochrome from Deinococcus radiodurans, incorporating biliverdin as the chromophore, can be engineered into monomeric, infrared-fluorescent proteins (IFPs), with excitation and emission maxima of 684 and 708 nm, respectively; extinction coefficient 〉90,000 M(-1) cm(-1); and quantum yield of 0.07. IFPs express well in mammalian cells and mice and spontaneously incorporate biliverdin, which is ubiquitous as the initial intermediate in heme catabolism but has negligible fluorescence by itself. Because their wavelengths penetrate tissue well, IFPs are suitable for whole-body imaging. The IFPs developed here provide a scaffold for further engineering.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2763207/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2763207/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shu, Xiaokun -- Royant, Antoine -- Lin, Michael Z -- Aguilera, Todd A -- Lev-Ram, Varda -- Steinbach, Paul A -- Tsien, Roger Y -- R01 CA158448/CA/NCI NIH HHS/ -- R01 GM086197/GM/NIGMS NIH HHS/ -- R01 GM086197-01/GM/NIGMS NIH HHS/ -- R01 NS027177/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 May 8;324(5928):804-7. doi: 10.1126/science.1168683.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of California at San Diego, 9500 Gilman Drive, La Jolla, CA 92093-0647, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19423828" target="_blank"〉PubMed〈/a〉
