    Description: Malaria exacts a toll of disease to people in the Tropics that seems incomprehensible to those only familiar with medicine and human health in the developed world. The methods of molecular biology, immunology, and cell biology are now being used to develop an antimalarial vaccine. The Plasmodium parasites that cause malaria have many stages in their life cycle. Each stage is antigenically distinct and potentially could be interrupted by different vaccines. However, achieving complete protection by vaccination may require a better understanding of the complexities of B- and T-cell priming in natural infections and the development of an appropriate adjuvant for use in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, L H -- Howard, R J -- Carter, R -- Good, M F -- Nussenzweig, V -- Nussenzweig, R S -- P01-AI17429/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1986 Dec 12;234(4782):1349-56.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2431481" target="_blank"〉PubMed〈/a〉

    Description: Partial amino acid sequence analysis of a purified lymphocyte homing receptor demonstrates the presence of two amino termini, one of which corresponds precisely to the amino terminus of ubiquitin. This observation extends the province of this conserved polypeptide to the cell surface and leads to a proposed model of the receptor complex as a core polypeptide modified by glycosylation and ubiquitination. Independent antibodies to ubiquitin serve to identify additional cell surface species, an indication that ubiquitination of cell surface proteins may be more general. It is proposed that functional binding of lymphocytes to lymph node high endothelial venules might involve the ubiquitinated region of the receptor; if true, cell surface ubiquitin could play a more general role in cell-cell interaction and adhesion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Siegelman, M -- Bond, M W -- Gallatin, W M -- St John, T -- Smith, H T -- Fried, V A -- Weissman, I L -- AI 19512/AI/NIAID NIH HHS/ -- CA 09151/CA/NCI NIH HHS/ -- GM 31461/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Feb 21;231(4740):823-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3003913" target="_blank"〉PubMed〈/a〉

    Description: Insect juvenile hormones are metabolized in numerous species of caterpillars by low abundance, highly specific esterases. Because of their role in regulating and possibly disrupting juvenile hormone titer and thus insect metamorphosis, they are of interest to developmental biologists as well as scientists interested in selective insect control. However, the enzymes have defied attempts to purify and characterize them. Juvenile hormone esterase activity can be inhibited by a variety of 3-substituted 1,1,1-trifluoropropanone sulfides. These apparent transition state analogs were used as ligands and eluting agents to purify juvenile hormone esterase from four insect species from 500-fold to over 1000-fold in high yield. After elution from the affinity column, the enzymes were radiolabeled with paraoxon and analyzed by electrophoresis, and the results demonstrate a high degree of purity. Transition state analogs may be useful for the affinity purification of other enzymes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abdel-Aal, Y A -- Hammock, B D -- New York, N.Y. -- Science. 1986 Sep 5;233(4768):1073-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3738525" target="_blank"〉PubMed〈/a〉

    Description: A glutamine synthetase gene from alfalfa (Medicago sativa) has been expressed in Escherichia coli after fusion of bacterial transcription and translation signals to a complete alfalfa glutamine synthetase coding sequence. Synthesis of the alfalfa glutamine synthetase enzyme in Escherichia coli was demonstrated by functional genetic complementation of a glutamine synthetase-deficient mutant and by immunoblotting analysis. These results should facilitate protein engineering and structure-function analysis of the plant enzyme.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉DasSarma, S -- Tischer, E -- Goodman, H M -- New York, N.Y. -- Science. 1986 Jun 6;232(4755):1242-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2871626" target="_blank"〉PubMed〈/a〉

    Description: Several molecular theories of aging postulate that there are age-dependent changes in gene expression and that these changes contribute to the reduction in the viability of senescent cells. High-resolution, semiautomated, quantitative two-dimensional gel electrophoresis of many soluble proteins was used to test this hypothesis in Drosophila. Two-dimensional protein gel patterns were analyzed for each of three age groups of [(35)S]methionine-labeled adult male Drosophila melanogaster, which, except for their spermatocytes, consist entirely of fixed postmitotic cells. Seven relatively abundant polypeptides expressed in middle-aged (28-day-old) flies were absent in both young(10-day-old) and old (44-day-old) flies. Quantitative analyses of an additional 100 polypeptides were carried out by computer-assisted microdensitometry of fluorograms of the gel preparations. These analyses revealed a significant age-related heterogeneity in the quantitative distribution of radiolabel in these proteins. The data indicate that the qualitative pattern of gene expression is identical in young and old flies, but that profound quantitative changes occur in the expression of proteins during the Drosophila life-span.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fleming, J E -- Quattrocki, E -- Latter, G -- Miquel, J -- Marcuson, R -- Zuckerkandl, E -- Bensch, K G -- New York, N.Y. -- Science. 1986 Mar 7;231(4742):1157-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3080809" target="_blank"〉PubMed〈/a〉

    Description: The generally mild bleeding disorder of von Willebrand disease is associated with abnormalities of two distinct plasma proteins, the large multimeric von Willebrand factor (vWF), which mediates platelet adhesion, and von Willebrand antigen II (vW AgII), which is of unknown function. The two proteins were found to have a common biosynthetic origin in endothelial cells and megakaryocytes, which explains their simultaneous absence in the severe form of this hereditary disease. Shared amino acid sequences from a 100-kilodalton plasma glycoprotein and from vW AgII are identical to amino acid sequences predicted from a complementary DNA clone encoding the 5' end of vWF. In addition, these proteins have identical molecular weights and immunologic cross reactivities. Monoclonal antibodies prepared against both proteins recognize epitopes on the pro-vWF subunit and on a 100-kilodalton protein that are not present on the mature vWF subunit in endothelial cell lysates. In contrast, polyclonal antibodies against vWF recognize both pro-vWF and vWF subunits. Thus, the 100-kilodalton plasma glycoprotein and vW AgII are identical proteins and represent an extremely large propolypeptide that is first cleaved from pro-vWF during intracellular processing and then released into plasma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fay, P J -- Kawai, Y -- Wagner, D D -- Ginsburg, D -- Bonthron, D -- Ohlsson-Wilhelm, B M -- Chavin, S I -- Abraham, G N -- Handin, R I -- Orkin, S H -- HL-30616/HL/NHLBI NIH HHS/ -- HL-34050/HL/NHLBI NIH HHS/ -- HL-34787/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 May 23;232(4753):995-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3486471" target="_blank"〉PubMed〈/a〉

    Description: Structural data are now available for comparing a penicillin target enzyme, the D-alanyl-D-alanine-peptidase from Streptomyces R61, with a penicillin-hydrolyzing enzyme, the beta-lactamase from Bacillus licheniformis 749/C. Although the two enzymes have distinct catalytic properties and lack relatedness in their overall amino acid sequences except near the active-site serine, the significant similarity found by x-ray crystallography in the spatial arrangement of the elements of secondary structure provides strong support for earlier hypotheses that beta-lactamases arose from penicillin-sensitive D-alanyl-D-alanine-peptidases involved in bacterial wall peptidoglycan metabolism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelly, J A -- Dideberg, O -- Charlier, P -- Wery, J P -- Libert, M -- Moews, P C -- Knox, J R -- Duez, C -- Fraipont, C -- Joris, B -- 10RRO1955-01/RR/NCRR NIH HHS/ -- AI-10925/AI/NIAID NIH HHS/ -- AI-16702/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1986 Mar 21;231(4744):1429-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3082007" target="_blank"〉PubMed〈/a〉

    Description: In a study performed to determine which regions of the human T-cell lymphotrophic virus type III (HTLV-III) may represent vaccine candidates to prevent the acquired immune deficiency syndrome (AIDS), a synthetic peptide corresponding to amino acid sequence 735 to 752 of the precursor envelope glycoprotein of HTLV-III was used to immunize rabbits. The resulting rabbit antiserum to the synthetic peptide specifically recognized the precursor envelope glycoprotein (gp160) of HTLV-III. Human sera positive for antibody to HTLV-III reacted with this peptide. These findings indicate that synthetic peptides can be used to induce an immune response directed against a native envelope glycoprotein epitope of HTLV-III. The data are discussed in terms of using synthetic peptides to identify antigenic determinants involved in the induction of protective immunity and possibly as vaccine candidates against the etiologic agent of AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kennedy, R C -- Henkel, R D -- Pauletti, D -- Allan, J S -- Lee, T H -- Essex, M -- Dreesman, G R -- N0I-HL-23505/HL/NHLBI NIH HHS/ -- R23-AI-22307-01/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1986 Mar 28;231(4745):1556-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3006246" target="_blank"〉PubMed〈/a〉

    Description: To characterize the precursor of mammalian thyrotropin-releasing hormone (TRH), a rat hypothalamic lambda gt11 library was screened with an antiserum directed against a synthetic peptide representing a portion of the rat TRH prohormone. The nucleotide sequence of the immunopositive complementary DNA encoded a protein with a molecular weight of 29,247. This protein contained five copies of the sequence Gln-His-Pro-Gly flanked by paired basic amino acids and could therefore generate five TRH molecules. In addition, potential cleavage sites in the TRH precursor could produce other non-TRH peptides, which may be secreted. In situ hybridization to rat brain sections demonstrated that the pre-proTRH complementary DNA detected neurons concentrated in the parvocellular division of the paraventricular nucleus, the same location as cells detected by immunohistochemistry. These findings indicate that mammalian TRH arises by posttranslational processing of a larger precursor protein. The ability of the TRH prohormone to generate multiple copies of the bioactive peptide may be an important mechanism in the amplification of hormone production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lechan, R M -- Wu, P -- Jackson, I M -- Wolf, H -- Cooperman, S -- Mandel, G -- Goodman, R H -- AM 34540/AM/NIADDK NIH HHS/ -- CA 37370/CA/NCI NIH HHS/ -- P30 AM 39428/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1986 Jan 10;231(4734):159-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3079917" target="_blank"〉PubMed〈/a〉

    Description: Addition of mouse interferon-alpha/beta (IFN) to confluent, quiescent BALB/c 3T3 (clone A31) mouse fibroblasts resulted in a block or delay in serum-induced activation of the cell cycle. It was necessary to add IFN within 6 hours after serum stimulation to inhibit nuclear labeling with [3H]thymidine. This is consistent with the time required for platelet-derived growth factor (PDGF) to induce cells to become competent to respond to additional growth factors present in platelet-poor plasma. Simultaneous addition of IFN with PDGF inhibited the PDGF-induced synthesis of a 29-kilodalton and a 35-kilodalton protein that normally occurs within 1 hour after PDGF addition. IFN also suppressed the general increase in protein synthesis that occurs by the fifth hour after PDGF addition. These results show that IFN antagonizes the action of PDGF, thereby interfering with the activation of Go cells for G1 traverse and S-phase entry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, S L -- Kikuchi, T -- Pledger, W J -- Tamm, I -- CA 18213/CA/NCI NIH HHS/ -- CA 18608/CA/NCI NIH HHS/ -- CA 42713/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 Jul 18;233(4761):356-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3726533" target="_blank"〉PubMed〈/a〉

    Description: A novel lymphokine with apparent molecular size of 10 to 12 kilodaltons is secreted from helper T cell clones within hours after cross-linking their T cell antigen-MHC (major histocompatibility complex) receptors (T3-Ti). This lymphokine, termed interleukin-4A (IL-4A), stimulates resting lymphocytes by binding to a surface component (or components) of the alternative T11 pathway and subsequently by inducing interleukin-2 (IL-2) receptors. The activation process is neither dependent on antigen specificities of the recruited population or the presence of macrophages. It appears, therefore, that IL-4A is a mediator involved in amplifying the T cell immune response.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Milanese, C -- Richardson, N E -- Reinherz, E L -- AI 21226/AI/NIAID NIH HHS/ -- CA 40134/CA/NCI NIH HHS/ -- R0I AI 19807/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1986 Mar 7;231(4742):1118-22.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2935936" target="_blank"〉PubMed〈/a〉

    Description: Immunization with either an Escherichia coli recombinant segment of the human T-cell lymphotropic virus (HTLV-III/LAV) envelope protein (gp 120) or with deglycosylated gp 120 envelope protein produced antibodies that neutralize HTLV-III/LAV infection in vitro. Virus neutralization titers of these antisera were equivalent to those obtained with purified native gp120 as immunogen. This localizes at least one class of neutralizing epitopes to the carboxyl-terminal half of the molecule. In addition, native gp120 prevented HTLV-III/LAV--mediated cell fusion, whereas the recombinant gp120 fragment did not. This shows that although glycosylation is not required for induction of neutralizing antibodies, it may be important for interaction with CD4, the virus receptor. A segment of the HTLV-III/LAV envelope produced in E. coli may be an important ingredient of a vaccine for acquired immune deficiency syndrome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Putney, S D -- Matthews, T J -- Robey, W G -- Lynn, D L -- Robert-Guroff, M -- Mueller, W T -- Langlois, A J -- Ghrayeb, J -- Petteway, S R Jr -- Weinhold, K J -- 1PO1-CA43447-01/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 Dec 12;234(4782):1392-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2431482" target="_blank"〉PubMed〈/a〉

    Description: The myb gene is the transforming oncogene of the avian myeloblastosis virus (AMV); its normal cellular homolog, c-myb, is conserved across a broad span of evolution. In humans, c-myb is expressed in malignant hematopoietic cell lines and in primary hematopoietic tumors. Partial complementary DNA clones were generated from blast cells of patients with acute myelogenous leukemia. The sequences of the clones were compared to the c-myb of other species, as well as the v-myb of AMV. In addition, the carboxyl terminal region of human c-myb was placed in an expression vector to obtain protein for the generation of antiserum, which was used to identify the human c-myb gene product. Like v-myb, this protein was found within the nucleus of leukemic cells where it was associated with the nuclear matrix. These studies provide further evidence that c-myb might be involved in human leukemia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Slamon, D J -- Boone, T C -- Murdock, D C -- Keith, D E -- Press, M F -- Larson, R A -- Souza, L M -- CA36827/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 Jul 18;233(4761):347-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3014652" target="_blank"〉PubMed〈/a〉

    Description: A monoclonal antibody was prepared against pooled homogenates of brain tissue from patients with Alzheimer's disease. This antibody recognizes an antigen present in much higher concentration in certain brain regions of Alzheimer patients than in normal brain. The antigen appears to be a protein present in neurons involved in the formation of neuritic plaques and neurofibrillary tangles, and in some morphologically normal neurons in sections from Alzheimer brains. Partial purification and Western blot analysis revealed the antigen from Alzheimer brain to be a single protein with a molecular weight of 68,000. Application of the same purification procedure to normal brain tissue results in the detection of small amounts of a protein of lower molecular weight.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wolozin, B L -- Pruchnicki, A -- Dickson, D W -- Davies, P -- CA13330/CA/NCI NIH HHS/ -- T32 GM7288/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 May 2;232(4750):648-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3083509" target="_blank"〉PubMed〈/a〉

    Description: The ninth component of complement (C9) and the pore-forming protein (PFP or perforin) from cytotoxic T lymphocytes polymerize to tubular lesions having an internal diameter of 100 A and 160 A, respectively, when bound to lipid bilayers. Polymerized C9, assembled by slow spontaneous or rapid Zn2+-induced polymerization, and polyperforin, which is assembled only in the presence of Ca2+, constitute large aqueous pores that are stable, nonselective for solutes, and insensitive to changes of membrane potential. Monospecific polyclonal antibodies to purified C9 and PFP show cross-reactivity, suggesting structural homology between the two molecules. The structural and functional homologies between these two killer molecules imply an active role for pore formation during cell lysis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Young, J D -- Cohn, Z A -- Podack, E R -- AI070127/AI/NIAID NIH HHS/ -- AI18525/AI/NIAID NIH HHS/ -- CA3019/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 Jul 11;233(4760):184-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2425429" target="_blank"〉PubMed〈/a〉

    Description: Interleukin-2 (IL-2) binds to both high- and low-affinity classes of IL-2 receptors on activated T lymphocytes. Only the high-affinity receptors are involved in receptor-mediated endocytosis and normally transduce the mitogenic signals of IL-2; however, the structural features distinguishing the high- and low-affinity receptors are unknown. When 125I-labeled IL-2 was chemically cross-linked to activated human T lymphocytes, two major bands were identified. First, as predicted, a 68- to 72-kilodalton band, consisting of IL-2 (15.5 kilodaltons) cross-linked to the IL-2 receptor (55 kilodaltons), was observed. Second, an unpredicted 85- to 92-kilodalton moiety was detected. This band was not present when IL-2 was cross-linked to transfected C127 cells, which exclusively express low-affinity receptors. The data presented are most consistent with the existence of a 70- to 77-kilodalton glycoprotein subunit (p70) which, upon associating with the 55-kilodalton low-affinity receptor (p55), transforms it into a high-affinity site. It is proposed that p55 and p70 be referred to as the alpha and beta subunits, respectively, of the high-affinity IL-2 receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sharon, M -- Klausner, R D -- Cullen, B R -- Chizzonite, R -- Leonard, W J -- New York, N.Y. -- Science. 1986 Nov 14;234(4778):859-63.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3095922" target="_blank"〉PubMed〈/a〉

    Description: Patients with rheumatic diseases often have circulating autoantibodies to nuclear components. The clinical significance of the antibodies is controversial, although in some cases they are valuable in the diagnosis of the disease. This report presents results of a study of Scl-70, an autoantigen recognized by sera of many patients with the most severe form of progressive systemic sclerosis. It was possible to show, by three independent criteria, that Scl-70 is the abundant nuclear enzyme DNA topoisomerase I. Therefore, antibody probes of high titer and high affinity are now available for the study of this important nuclear enzyme.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shero, J H -- Bordwell, B -- Rothfield, N F -- Earnshaw, W C -- GM-30985/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Feb 14;231(4739):737-40.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3003910" target="_blank"〉PubMed〈/a〉

    Description: The current pertussis vaccines, although efficacious, in some instances produce undesirable side effects. Molecular engineering of pertussis toxin, the major protective antigen, could provide a safer, new generation of vaccines against whooping cough. As a first critical step in the development of such a vaccine, the complete nucleotide sequence of the pertussis toxin gene was determined and the amino acid sequences of the individual subunits were deduced. All five subunits are coded by closely linked cistrons. A promoter-like structure was found in the 5'-flanking region, suggesting that the toxin is expressed through a polycistronic messenger RNA. The order of the cistrons is S1, S2, S4, S5, and S3. All subunits contain signal peptides of variable length. The calculated molecular weights of the mature subunits are 26,024 for S1, 21,924 for S2, 21,873 for S3, 12,058 for S4, and 11,013 for S5. Subunits S2 and S3 share 70% amino acid homology and 75% nucleotide homology. Subunit S1 contains two regions of eight amino acids homologous to analogous regions in the A subunit of both cholera and Escherichia coli heat labile toxins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Locht, C -- Keith, J M -- New York, N.Y. -- Science. 1986 Jun 6;232(4755):1258-64.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3704651" target="_blank"〉PubMed〈/a〉

    Description: Antibodies were raised against a synthetic peptide corresponding to 14 amino acid residues at the COOH-terminus of a protein deduced from the human c-erbB-2 nucleotide sequence. These antibodies immunoprecipitated a 185-kilodalton glycoprotein from MKN-7 adenocarcinoma cells. Incubation of the immunoprecipitates with (gamma-32P)ATP resulted in the phosphorylation of this protein on tyrosine residues. These results indicate that the human c-erbB-2 gene product is the 185-kilodalton glycoprotein that is associated with tyrosine kinase activity. Although the c-erbB-2 protein was predicted to encode a protein very similar to epidermal growth factor (EGF) receptor, EGF did not stimulate this kinase activity either in vivo or in vitro.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Akiyama, T -- Sudo, C -- Ogawara, H -- Toyoshima, K -- Yamamoto, T -- New York, N.Y. -- Science. 1986 Jun 27;232(4758):1644-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3012781" target="_blank"〉PubMed〈/a〉

    Description: Electric fields can be manipulated by a method in which multiple electrodes are arranged along a closed contour and clamped to predetermined electric potentials. This method may be applied to a broad range of problems in the separation of macromolecules by gel electrophoresis. DNA molecules as large as 2 megabases can be well separated with a contour-clamped homogeneous electric field alternating between two orientations 120 degrees apart. The pattern of separation is independent of position in the gel, which is an advantage over previous methods. DNA less than 50 kilobases can be separated without distortion even at high voltage with a nonalternating contour-clamped homogeneous field. Decreased band broadening in DNA less than 200 bases can be achieved with a contour-clamped inhomogeneous field.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chu, G -- Vollrath, D -- Davis, R W -- GM21891-12/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Dec 19;234(4783):1582-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3538420" target="_blank"〉PubMed〈/a〉

    Description: In gel electrophoresis, nucleic acids and protein-detergent complexes larger than a threshold size all migrate at the same rate. For DNA molecules, this effect can be overcome by the simple procedure of periodically inverting the electric field. Tuning the frequency of the field inversions from 10 to 0.01 hertz, makes it possible to resolve selectively DNA's in the size range 15 to greater than 700 kilobase pairs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carle, G F -- Frank, M -- Olson, M V -- New York, N.Y. -- Science. 1986 Apr 4;232(4746):65-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3952500" target="_blank"〉PubMed〈/a〉

    Description: While much information exists about the structure and function of the clonally distributed T cell receptor (TCR) alpha beta heterodimer, little is known about the gamma protein, the product of a third rearranging TCR gene. An antiserum to a carboxyl-terminal peptide common to several of the murine gamma chain constant regions and a monoclonal antibody to the murine T3 complex were used to identify products of this TCR gene family in a subpopulation of Lyt2-, L3T4- thymocytes. This subpopulation does not express TCR alpha or full-length TCR beta messenger RNA. The gamma chain is a 35-kilodalton (kD) protein that is disulfide-bonded to a 45-kD partner and is associated with the T3 complex. Analysis of the glycosylation pattern of this thymic gamma chain revealed that the major variable region gamma (V gamma) gene transcribed in activated peripheral T cells is absent from this subpopulation. The cells that bear this second T cell receptor may therefore represent a distinct lineage differentiating within the thymus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lew, A M -- Pardoll, D M -- Maloy, W L -- Fowlkes, B J -- Kruisbeek, A -- Cheng, S F -- Germain, R N -- Bluestone, J A -- Schwartz, R H -- Coligan, J E -- New York, N.Y. -- Science. 1986 Dec 12;234(4782):1401-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3787252" target="_blank"〉PubMed〈/a〉

    Description: The mechanism by which the estrogen receptor and other steroid hormone receptors regulate gene expression in eukaryotic cells is not well understood. In this study, a complementary DNA clone containing the entire translated portion of the messenger RNA for the estrogen receptor from MCF-7 human breast cancer cells was sequenced and then expressed in Chinese hamster ovary (CHO-K1) cells to give a functional protein. An open reading frame of 1785 nucleotides in the complementary DNA corresponded to a polypeptide of 595 amino acids and a molecular weight of 66,200, which is in good agreement with published molecular weight values of 65,000 to 70,000 for the estrogen receptor. Homogenates of transformed Chinese hamster ovary cells containing a protein that bound [3H]estradiol and sedimented as a 4S complex in salt-containing sucrose gradients and as an 8 to 9S complex in the absence of salt. Interaction of this receptor-[3H]estradiol complex with a monoclonal antibody that is specific for primate ER confirms the identity of the expressed complementary DNA as human estrogen receptor. Amino acid sequence comparisons revealed significant regional homology among the human estrogen receptor, the human glucocorticoid receptor, and the putative v-erbA oncogene product. This suggests that steroid receptor genes and the avian erythroblastosis viral oncogene are derived from a common primordial gene. The homologous region, which is rich in cysteine, lysine, and arginine, may represent the DNA-binding domain of these proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Greene, G L -- Gilna, P -- Waterfield, M -- Baker, A -- Hort, Y -- Shine, J -- CA-02897/CA/NCI NIH HHS/ -- HD17103/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1986 Mar 7;231(4742):1150-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3753802" target="_blank"〉PubMed〈/a〉

    Description: The DNA of the HTLV-III/LAV group of retroviruses contains certain additional open reading frames that are not found in typical avian or mammalian retroviruses. The role of these sequences in encoding for gene products that may be related to pathogenesis remains to be resolved. An open reading frame whose 5' end overlaps with the pol gene, but is unrelated to the env gene, has been observed in HTLV-III/LAV and visna virus, both cytopathic mammalian retroviruses. Evidence presented here shows that this open reading frame is a bona fide coding sequence of HTLV-III/LAV and that its product, a protein with a molecular weight of 23,000, induces antibody production in the natural course of infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, T H -- Coligan, J E -- Allan, J S -- McLane, M F -- Groopman, J E -- Essex, M -- CA 18216/CA/NCI NIH HHS/ -- CA 37466/CA/NCI NIH HHS/ -- ST 32 CA 9382/ST/OHS HRSA HHS/ -- etc. -- New York, N.Y. -- Science. 1986 Mar 28;231(4745):1546-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3006243" target="_blank"〉PubMed〈/a〉
