    Description: The Drosophila melanogaster gene insulin-like receptor (InR) is homologous to mammalian insulin receptors as well as to Caenorhabditis elegans daf-2, a signal transducer regulating worm dauer formation and adult longevity. We describe a heteroallelic, hypomorphic genotype of mutant InR, which yields dwarf females with up to an 85% extension of adult longevity and dwarf males with reduced late age-specific mortality. Treatment of the long-lived InR dwarfs with a juvenile hormone analog restores life expectancy toward that of wild-type controls. We conclude that juvenile hormone deficiency, which results from InR signal pathway mutation, is sufficient to extend life-span, and that in flies, insulin-like ligands nonautonomously mediate aging through retardation of growth or activation of specific endocrine tissue.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tatar, M -- Kopelman, A -- Epstein, D -- Tu, M P -- Yin, C M -- Garofalo, R S -- R01 AG16632/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2001 Apr 6;292(5514):107-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Brown University, Providence, RI 02912, USA., University of Massachusetts, Amherst, MA 01003, USA.

    Description: The mevalonate-derived portion of a prenylated protein from Chinese hamster ovary cells has been established as diterpenoid (C20). This group is linked to a carboxyl-terminal cysteine as a thioether. It was removed from the protein by hydrazinolysis followed by Raney nickel desulfurization, and the resulting hydrocarbon fraction was analyzed by gas chromatography-mass spectrometry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rilling, H C -- Breunger, E -- Epstein, W W -- Crain, P F -- GM 29812/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Jan 19;247(4940):318-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Utah, Salt Lake City 84112.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2296720" target="_blank"〉PubMed〈/a〉

    Description: Consistent, high-level, vaccine-induced protection against human malaria has only been achieved by inoculation of Plasmodium falciparum (Pf) sporozoites (SPZ) by mosquito bites. We report that the PfSPZ Vaccine--composed of attenuated, aseptic, purified, cryopreserved PfSPZ--was safe and well tolerated when administered four to six times intravenously (IV) to 40 adults. Zero of six subjects receiving five doses and three of nine subjects receiving four doses of 1.35 x 10(5) PfSPZ Vaccine and five of six nonvaccinated controls developed malaria after controlled human malaria infection (P = 0.015 in the five-dose group and P = 0.028 for overall, both versus controls). PfSPZ-specific antibody and T cell responses were dose-dependent. These data indicate that there is a dose-dependent immunological threshold for establishing high-level protection against malaria that can be achieved with IV administration of a vaccine that is safe and meets regulatory standards.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seder, Robert A -- Chang, Lee-Jah -- Enama, Mary E -- Zephir, Kathryn L -- Sarwar, Uzma N -- Gordon, Ingelise J -- Holman, LaSonji A -- James, Eric R -- Billingsley, Peter F -- Gunasekera, Anusha -- Richman, Adam -- Chakravarty, Sumana -- Manoj, Anita -- Velmurugan, Soundarapandian -- Li, MingLin -- Ruben, Adam J -- Li, Tao -- Eappen, Abraham G -- Stafford, Richard E -- Plummer, Sarah H -- Hendel, Cynthia S -- Novik, Laura -- Costner, Pamela J M -- Mendoza, Floreliz H -- Saunders, Jamie G -- Nason, Martha C -- Richardson, Jason H -- Murphy, Jittawadee -- Davidson, Silas A -- Richie, Thomas L -- Sedegah, Martha -- Sutamihardja, Awalludin -- Fahle, Gary A -- Lyke, Kirsten E -- Laurens, Matthew B -- Roederer, Mario -- Tewari, Kavita -- Epstein, Judith E -- Sim, B Kim Lee -- Ledgerwood, Julie E -- Graham, Barney S -- Hoffman, Stephen L -- VRC 312 Study Team -- 3R44AI055229-06S1/AI/NIAID NIH HHS/ -- 4R44AI055229-08/AI/NIAID NIH HHS/ -- 5R44AI058499-05/AI/NIAID NIH HHS/ -- N01-AI-40096/AI/NIAID NIH HHS/ -- Intramural NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Sep 20;341(6152):1359-65. doi: 10.1126/science.1241800.

    Description: The organization of myosin into motile cellular structures requires precise temporal and spatial regulation. Proteins containing a UCS (UNC-45/CRO1/She4p) domain are necessary for the incorporation of myosin into the contractile ring during cytokinesis and into thick filaments during muscle development. We report that the carboxyl-terminal regions of UNC-45 bound and exerted chaperone activity on the myosin head. The amino-terminal tetratricopeptide repeat domain of UNC-45 bound the molecular chaperone Hsp90. Thus, UNC-45 functions both as a molecular chaperone and as an Hsp90 co-chaperone for myosin, which can explain previous findings of altered assembly and decreased accumulation of myosin in UNC-45 mutants of Caenorhabditis elegans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barral, Jose M -- Hutagalung, Alex H -- Brinker, Achim -- Hartl, F Ulrich -- Epstein, Henry F -- New York, N.Y. -- Science. 2002 Jan 25;295(5555):669-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, Baylor College of Medicine, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11809970" target="_blank"〉PubMed〈/a〉

    Description: The basal cell nevus syndrome (BCNS) is characterized by developmental abnormalities and by the postnatal occurrence of cancers, especially basal cell carcinomas (BCCs), the most common human cancer. Heritable mutations in BCNS patients and a somatic mutation in a sporadic BCC were identified in a human homolog of the Drosophila patched (ptc) gene. The ptc gene encodes a transmembrane protein that in Drosophila acts in opposition to the Hedgehog signaling protein, controlling cell fates, patterning, and growth in numerous tissues. The human PTC gene appears to be crucial for proper embryonic development and for tumor suppression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johnson, R L -- Rothman, A L -- Xie, J -- Goodrich, L V -- Bare, J W -- Bonifas, J M -- Quinn, A G -- Myers, R M -- Cox, D R -- Epstein, E H Jr -- Scott, M P -- AR3995/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 1996 Jun 14;272(5268):1668-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental Biology, Howard Hughes Medical Institute, Stanford University School of Medicine, California 94305-5427, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8658145" target="_blank"〉PubMed〈/a〉

    Description: Cultured skin fibroblasts from patients with cystic fibrosis (CF) are more resistant to dexamethasone toxicity than are normal cells. We now report that, when fibroblasts cultured from obligate CF heterozygotes are exposed to dexamethasone, they have an intermediate survival compared to normal and homozygous CF cells. When dexamethasone survival was tested on cells from four patients undergoing amniocentesis, cells from a woman at risk of producing a child with CF showed significant dexamethasone resistance, similar to that of fibroblasts derived from lnown CF homozygotes; the other amniotic cell specimens showed dexamethasone sensitivity similar to that of normal skin fibroblasts. These data suggest that the dexamethasone resistance previously observed in skin fibroblasts may also be useful in the prenatal diagnosis of CF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Breslow, J L -- Epstein, J -- Fontaine, J H -- Forbes, G B -- New York, N.Y. -- Science. 1978 Jul 14;201(4351):180-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663650" target="_blank"〉PubMed〈/a〉

    Description: Plasma cholesterol sulfate concentration is increased in patients with recessive X-linked ichthyosis, a disease in which steroid sulfatase activity is absent. In these patients, cholesterol sulfate is found primarily in the low-density lipoprotein fraction of plasma, and the electrophoretic mobility of these lipoproteins is greatly increased.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Epstein, E H Jr -- Krauss, R M -- Shackleton, C H -- AM 28069/AM/NIADDK NIH HHS/ -- HL 18574/HL/NHLBI NIH HHS/ -- RR 00719/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1981 Nov 6;214(4521):659-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6945674" target="_blank"〉PubMed〈/a〉

    Description: Unexplained debilitating dementia or encephalopathy occurs frequently in adults and children with the acquired immune deficiency syndrome (AIDS). Brains from 15 individuals with AIDS and encephalopathy were examined by Southern analysis and in situ hybridization for the presence of human T-cell leukemia (lymphotropic) virus type III (HTLV-III), the virus believed to be the causative agent of AIDS. HTLV-III DNA was detected in the brains of five patients, and viral-specific RNA was detected in four of these. In view of these findings and the recent demonstration of morphologic and genetic relatedness between HTLV-III and visna virus, a lentivirus that causes a chronic degenerative neurologic disease in sheep, HTLV-III should be evaluated further as a possible cause of AIDS encephalopathy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shaw, G M -- Harper, M E -- Hahn, B H -- Epstein, L G -- Gajdusek, D C -- Price, R W -- Navia, B A -- Petito, C K -- O'Hara, C J -- Groopman, J E -- New York, N.Y. -- Science. 1985 Jan 11;227(4683):177-82.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2981429" target="_blank"〉PubMed〈/a〉

    Description: Cotton-top tamarins were inoculated with sufficient Epstein-Barr virus to induce multiple tumors in each animal within 14 to 21 days. The tumors consisted of large-cell lymphomas that contained multiple copies of the Epstein-Barr virus genome and generated Epstein-Barr virus-carrying cell lines showing no detectable consistent chromosomal abnormality. Hybridization of tumor DNA with immunoglobulin gene probes revealed that each lymphoma was oligo- or monoclonal in origin and that individual tumors from the same animal arose from different B-cell clones. Thus the virus induced multiple transformation events in tamarins in vivo to cause malignant tumors resembling the Epstein-Barr virus-associated lymphomas of patients with organ transplants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cleary, M L -- Epstein, M A -- Finerty, S -- Dorfman, R F -- Bornkamm, G W -- Kirkwood, J K -- Morgan, A J -- Sklar, J -- CA 34233/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 May 10;228(4700):722-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2986287" target="_blank"〉PubMed〈/a〉
