    Description: Human T cell lymphotropic virus I (HTLV-I) is the etiological agent for adult T cell leukemia and tropical spastic paraparesis (also termed HTLV-I-associated myelopathy). HTLV-I-infected peripheral blood T cells exhibit an initial phase of interleukin-2 (IL-2)-dependent growth; over time, by an unknown mechanism, the cells become IL-2-independent. Whereas the Jak kinases Jak1 and Jak3 and the signal transducer and activator of transcription proteins Stat3 and Stat5 are activated in normal T cells in response to IL-2, this signaling pathway was constitutively activated in HTLV-I-transformed cells. In HTLV-I-infected cord blood lymphocytes, the transition from IL-2-dependent to IL-2-independent growth correlated with the acquisition of a constitutively activated Jak-STAT pathway, which suggests that this pathway participates in HTLV-I-mediated T cell transformation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Migone, T S -- Lin, J X -- Cereseto, A -- Mulloy, J C -- O'Shea, J J -- Franchini, G -- Leonard, W J -- New York, N.Y. -- Science. 1995 Jul 7;269(5220):79-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Immunology, National Heart, Lung, and Blood Institute, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7604283" target="_blank"〉PubMed〈/a〉

    Description: A heptadecapeptide was identified and purified from porcine brain tissue as a ligand for an orphan heterotrimeric GTP-binding protein (G protein)-coupled receptor (LC132) that is similar in sequence to opioid receptors. This peptide, orphanin FQ, has a primary structure reminiscent of that of opioid peptides. Nanomolar concentrations of orphanin FQ inhibited forskolin-stimulated adenylyl cyclase activity in cells transfected with LC132. This inhibitory activity was not affected by the addition of opioid ligands, nor did the peptide activate opioid receptors. Orphanin FQ bound to its receptor in a saturable manner and with high affinity. When injected intracerebroventricularly into mice, orphanin FQ caused a decrease in locomotor activity but did not induce analgesia in the hot-plate test. However, the peptide produced hyperalgesia in the tail-flick assay. Thus, orphanin FQ may act as a transmitter in the brain by modulating nociceptive and locomotor behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reinscheid, R K -- Nothacker, H P -- Bourson, A -- Ardati, A -- Henningsen, R A -- Bunzow, J R -- Grandy, D K -- Langen, H -- Monsma, F J Jr -- Civelli, O -- DA 08562/DA/NIDA NIH HHS/ -- DA 09620/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1995 Nov 3;270(5237):792-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Pharma Division, Hoffmann-La Roche AG, Basel, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7481766" target="_blank"〉PubMed〈/a〉

    Description: Immune responses dominated by interleukin-4 (IL-4)-producing T helper type 2 (TH2) cells or by interferon gamma (IFN-gamma)-producing T helper type 1 (TH1) cells express distinctive protection against infection with different pathogens. Interleukin-4 promotes the differentiation of naive CD4+ T cells into IL-4 producers and suppresses their development into IFN-gamma producers. CD1-specific splenic CD4+NK1.1+ T cells, a numerically minor population, produced IL-4 promptly on in vivo stimulation. This T cell population was essential for the induction of IL-4-producing cells and for switching to immunoglobulin E, an IL-4-dependent event, in response to injection of antibodies to immunoglobulin D.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoshimoto, T -- Bendelac, A -- Watson, C -- Hu-Li, J -- Paul, W E -- New York, N.Y. -- Science. 1995 Dec 15;270(5243):1845-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunology, National Institute of Allergy and Infectious Diseases, National Institute of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8525383" target="_blank"〉PubMed〈/a〉

    Description: Fibroblast growth factors (FGFs) are thought to influence many processes in vertebrate development because of their diverse sites of expression and wide range of biological activities in in vitro culture systems. As a means of elucidating embryonic functions of FGF-4, gene targeting was used to generate mice harboring a disrupted Fgf4 gene. Embryos homozygous for the null allele underwent uterine implantation and induced uterine decidualization but did not develop substantially thereafter. As was consistent with their behavior in vivo, Fgf4 null embryos cultured in vitro displayed severely impaired proliferation of the inner cell mass, whereas growth and differentiation of the inner cell mass were rescued when null embryos were cultured in the presence of FGF-4 protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feldman, B -- Poueymirou, W -- Papaioannou, V E -- DeChiara, T M -- Goldfarb, M -- HD21988/HD/NICHD NIH HHS/ -- HD27198/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1995 Jan 13;267(5195):246-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Integrated Program in Cellular, Molecular, and Biophysical Studies, Columbia University College of Physicians and Surgeons, New York, NY 10032.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7809630" target="_blank"〉PubMed〈/a〉

    Description: Fas (also known as Apo1 and CD95) is a cell surface receptor involved in apoptotic cell death. Fas expression and function were analyzed in three children (including two siblings) with a lymphoproliferative syndrome, two of whom also had autoimmune disorders. A large deletion in the gene encoding Fas and no detectable cell surface expression characterized the most affected patient. Clinical manifestations in the two related patients were less severe: Fas-mediated apoptosis was impaired and a deletion within the intracytoplasmic domain was detected. These findings illustrate the crucial regulatory role of Fas and may provide a molecular basis for some autoimmune diseases in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rieux-Laucat, F -- Le Deist, F -- Hivroz, C -- Roberts, I A -- Debatin, K M -- Fischer, A -- de Villartay, J P -- New York, N.Y. -- Science. 1995 Jun 2;268(5215):1347-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut National de la Sante et de la Recherche Medicale (INSERM) U 429, Hopital Necker-Enfants Malades, Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7539157" target="_blank"〉PubMed〈/a〉

    Description: Deficiency in monoamine oxidase A (MAOA), an enzyme that degrades serotonin and norepinephrine, has recently been shown to be associated with aggressive behavior in men of a Dutch family. A line of transgenic mice was isolated in which transgene integration caused a deletion in the gene encoding MAOA, providing an animal model of MAOA deficiency. In pup brains, serotonin concentrations were increased up to ninefold, and serotonin-like immunoreactivity was present in catecholaminergic neurons. In pup and adult brains, norepinephrine concentrations were increased up to twofold, and cytoarchitectural changes were observed in the somatosensory cortex. Pup behavioral alterations, including trembling, difficulty in righting, and fearfulness were reversed by the serotonin synthesis inhibitor parachlorophenylalanine. Adults manifested a distinct behavioral syndrome, including enhanced aggression in males.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2844866/" 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/PMC2844866/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cases, O -- Seif, I -- Grimsby, J -- Gaspar, P -- Chen, K -- Pournin, S -- Muller, U -- Aguet, M -- Babinet, C -- Shih, J C -- K05 MH 00796/MH/NIMH NIH HHS/ -- R01 MH 37020/MH/NIMH NIH HHS/ -- R37 MH 39085/MH/NIMH NIH HHS/ -- R37 MH039085/MH/NIMH NIH HHS/ -- R37 MH039085-23/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1995 Jun 23;268(5218):1763-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre National de la Recherche Scientifique (CNRS), Unite de Recherche Associee (URA), Institut Curie, Orsay, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7792602" target="_blank"〉PubMed〈/a〉

    Description: Telomeres are the protein-DNA structures at the ends of eukaryotic chromosomes. In yeast, and probably most other eukaryotes, telomeres are essential. They allow the cell to distinguish intact from broken chromosomes, protect chromosomes from degradation, and are substrates for novel replication mechanisms. Telomeres are usually replicated by telomerase, a telomere-specific reverse transcriptase, although telomerase-independent mechanisms of telomere maintenance exist. Telomere replication is both cell cycle- and developmentally regulated, and its control is likely to be complex. Because telomere loss causes the kinds of chromosomal changes associated with cancer and aging, an understanding of telomere biology has medical relevance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zakian, V A -- New York, N.Y. -- Science. 1995 Dec 8;270(5242):1601-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Princeton University, NJ 08544, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7502069" target="_blank"〉PubMed〈/a〉

    Description: CD1 molecules are distantly related to the major histocompatibility complex (MHC) class I proteins. They are of unknown function. Screening random peptide phage display libraries with soluble empty mouse CD1 (mCD1) identified a peptide binding motif. It consists of three anchor positions occupied by aromatic or bulky hydrophobic amino acids. Equilibrium binding studies demonstrated that mCD1 binds peptides containing the appropriate motif with relatively high affinity. However, in contrast to classical MHC class I molecules, strong binding to mCD1 required relatively long peptides. Peptide-specific, mCD1-restricted T cell responses can be raised, which suggests that the findings are of immunological significance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Castano, A R -- Tangri, S -- Miller, J E -- Holcombe, H R -- Jackson, M R -- Huse, W D -- Kronenberg, M -- Peterson, P A -- New York, N.Y. -- Science. 1995 Jul 14;269(5221):223-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7542403" target="_blank"〉PubMed〈/a〉

    Description: Eukaryotic chromosomes are capped with repetitive telomere sequences that protect the ends from damage and rearrangements. Telomere repeats are synthesized by telomerase, a ribonucleic acid (RNA)-protein complex. Here, the cloning of the RNA component of human telomerase, termed hTR, is described. The template region of hTR encompasses 11 nucleotides (5'-CUAACCCUAAC) complementary to the human telomere sequence (TTAGGG)n. Germline tissues and tumor cell lines expressed more hTR than normal somatic cells and tissues, which have no detectable telomerase activity. Human cell lines that expressed hTR mutated in the template region generated the predicted mutant telomerase activity. HeLa cells transfected with an antisense hTR lost telomeric DNA and began to die after 23 to 26 doublings. Thus, human telomerase is a critical enzyme for the long-term proliferation of immortal tumor cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feng, J -- Funk, W D -- Wang, S S -- Weinrich, S L -- Avilion, A A -- Chiu, C P -- Adams, R R -- Chang, E -- Allsopp, R C -- Yu, J -- AG09383/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 1995 Sep 1;269(5228):1236-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Geron Corporation, Menlo Park, CA 94025, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7544491" target="_blank"〉PubMed〈/a〉
