    Description: A DNA sequence coding for the immunogenic capsid protein VP3 of foot-and-mouth disease virus A12, prepared from the virion RNA, was ligated to a plasmid designed to express a chimeric protein from the Escherichia coli tryptophan promoter-operator system. When Escherichia coli transformed with this plasmid was grown in tryptophan-depleted media, approximately 17 percent of the total cellular protein was found to be an insoluble and stable chimeric protein. The purified chimeric protein competed equally on a molar basis with VP3 for specific antibodies to foot-and-mouth disease virus. When inoculated into six cattle and two swine, this protein elicited high levels of neutralizing antibody and protection against challenge with foot-and-mouth disease virus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kleid, D G -- Yansura, D -- Small, B -- Dowbenko, D -- Moore, D M -- Grubman, M J -- McKercher, P D -- Morgan, D O -- Robertson, B H -- Bachrach, H L -- New York, N.Y. -- Science. 1981 Dec 4;214(4525):1125-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6272395" target="_blank"〉PubMed〈/a〉

    Description: Hybridoma technology has made it possible to introduce into continuous culture normal antibody-forming cells and to obtain large amounts of the immunoglobulin produced by each of these cells. Examination of the structure of a number of monoclonal antibodies that react with a single antigen has provided new information on the structural basis of the specificity and affinity of antibodies. Comparisons of families of monoclonal antibodies derived from a single germ line gene revealed the importance of somatic mutation in generating antibody diversity. Monoclonal antibodies that react with variable regions of other monoclonals allow the further dissection and modulation of the immune response. Finally, the continued somatic instability of immunoglobulin genes in cultured antibody-forming cells makes it possible to determine the rate of somatic mutation and to generate mutant monoclonal antibodies that may be more effective serological reagents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Teillaud, J L -- Desaymard, C -- Giusti, A M -- Haseltine, B -- Pollock, R R -- Yelton, D E -- Zack, D J -- Scharff, M D -- 5T32GM7288/GM/NIGMS NIH HHS/ -- AI05231/AI/NIAID NIH HHS/ -- AI10702/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1983 Nov 18;222(4625):721-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6356353" target="_blank"〉PubMed〈/a〉

    Description: An analog of luteinizing hormone-releasing hormone containing a gamma-lactam as a conformational constraint has been prepared with the use of a novel cyclization of a methionine sulfonium salt. The analog is more active as a luteinizing hormone-releasing hormone agonist that the parent hormone, and provides evidence for a bioactive conformation containing a beta-turn.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Freidinger, R M -- Veber, D F -- Perlow, D S -- Brooks, J R -- Saperstein, R -- New York, N.Y. -- Science. 1980 Nov 7;210(4470):656-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7001627" target="_blank"〉PubMed〈/a〉

    Description: Urotensin I, purified from extracts of the urophysis of a teleost fish (Catostomus commersoni), exhibits potent hypotensive activity (mammals and birds) and corticotropin-releasing activity (both fish and mammals). The primary structure of this 41-residue peptide was determined to be H-Asn-Asp-Asp-Pro-Pro-Ile-Ser-Ile-Asp-Leu-Thr-Phe-His-Leu-Leu-Arg-Asn-Met-Ile-Glu - Met-Ala-Arg-Ile-Glu-Asn-Glu-Arg-Glu-Gln-Ala-Gly-Leu-Asn-Arg-Lys-Tyr-Leu-Asp-Glu -Val-NH2. Extraction with 0.1N HCl at 100 degrees C cleaves the amino-terminal tripeptide, yeilding a fully active analog, urotensin I(4-41). The amino acid sequence was confirmed by measuring the biological activity of synthetic urotensin I(4-41). Urotensin I exhibits a striking sequence homology with ovine corticotropin-releasing factor and with frog sauvagine. These three peptides exhibit similar activities in biological test systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lederis, K -- Letter, A -- McMaster, D -- Moore, G -- Schlesinger, D -- New York, N.Y. -- Science. 1982 Oct 8;218(4568):162-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6981844" target="_blank"〉PubMed〈/a〉

    Description: The gene for the circumsporozoite (CS) protein of Plasmodium falciparum has been cloned and its nucleotide sequence determined. The gene encodes a protein of 412 amino acids as deduced from the nucleotide sequence. The protein contains 41 tandem repeats of a tetrapeptide, 37 of which are Asn-Ala-Asn-Pro and four of which are Asn-Val-Asp-Pro. Monoclonal antibodies against the CS protein of Plasmodium falciparum were inhibited from binding to the protein by synthetic peptides of the repeat sequence. The CS protein of Plasmodium falciparum and the CS protein of a simian malaria parasite, Plasmodium knowlesi, have two regions of homology, one of which is present on either side of the repeat. One region contains 12 of 13 identical amino acids. Within the nucleotide sequence of this region, 25 of 27 nucleotides are conserved. The conservation of these regions in parasites widely separated in evolution suggests that they may have a function such as binding to liver cells and may represent an invariant target for immunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dame, J B -- Williams, J L -- McCutchan, T F -- Weber, J L -- Wirtz, R A -- Hockmeyer, W T -- Maloy, W L -- Haynes, J D -- Schneider, I -- Roberts, D -- New York, N.Y. -- Science. 1984 Aug 10;225(4662):593-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6204383" target="_blank"〉PubMed〈/a〉

    Description: The guanosine triphosphate-binding proteins (G proteins) found in a variety of tissues transduce signals generated by ligand binding to cell surface receptors into changes in intracellular metabolism. Amino acid sequences of peptides prepared by partial proteolysis of the alpha subunit of a bovine brain G protein and the alpha subunit of rod outer-segment transducin were determined. The two proteins show regions of sequence identity as well as regions of diversity. A portion of the amino-terminal peptide sequence of each protein is highly homologous with the corresponding region in the ras protein (a protooncogene product). These similarities suggest that G proteins and ras proteins may have analogous functions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hurley, J B -- Simon, M I -- Teplow, D B -- Robishaw, J D -- Gilman, A G -- GM 09731-02/GM/NIGMS NIH HHS/ -- NS 18153/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1984 Nov 16;226(4676):860-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6436980" target="_blank"〉PubMed〈/a〉

    Description: A data base of the National Center for Health Statistics, Health and Nutrition Examination Survey I (HANES I), was used to perform a computer-assisted, comprehensive analysis of the relation of 17 nutrients to the blood pressure profile of adult Americans. Subjects were 10,372 individuals, 18 to 74 years of age, who denied a history of hypertension and intentional modification of their diet. Significant decreases in the consumption of calcium, potassium, vitamin A, and vitamin C were identified as the nutritional factors that distinguished hypertensive from normotensive subjects. Lower calcium intake was the most consistent factor in hypertensive individuals. Across the population, higher intakes of calcium, potassium, and sodium were associated with lower mean systolic blood pressure and lower absolute risk of hypertension. Increments of dietary calcium were also negatively correlated with body mass. Even though these correlations cannot be accepted as proof of causation, they have implications for future studies of the association of nutritional factors and dietary patterns with hypertension in America.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McCarron, D A -- Morris, C D -- Henry, H J -- Stanton, J L -- New York, N.Y. -- Science. 1984 Jun 29;224(4656):1392-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6729459" target="_blank"〉PubMed〈/a〉

    Description: The human T-cell leukemia viruses HTLV-I and HTLV-II are unique among the transforming retroviruses of vertebrates in their ability to transform human T cells in vitro and in their close association with human malignancies (T-cell lymphomas and leukemia). Their genomes are relatively simple, containing the genes gag, pol, env, and a 3' region termed "X." This 3' region may be responsible for the transforming potential of the viruses. The existence of proteins encoded by the 3' region has been postulated on the basis of multiple open reading frames. In the present study this region is shown to contain a gene encoding a protein of 40 kilodaltons in HTLV-I and 37 kilodaltons in HTLV-II. It is proposed that these proteins be called, respectively, p40xI and p37xII.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Slamon, D J -- Shimotohno, K -- Cline, M J -- Golde, D W -- Chen, I S -- CA 16042/CA/NCI NIH HHS/ -- CA 32737/CA/NCI NIH HHS/ -- RR 00865/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1984 Oct 5;226(4670):61-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6089351" target="_blank"〉PubMed〈/a〉
