    Description: A lectin in Giardia lamblia was activated by secretions from the human duodenum, the environment where the parasite lives. Incubation of the secretions with trypsin inhibitors prevented the appearance of lectin activity, implicating proteases as the activating agent. Accordingly, lectin activation was also produced by crystalline trypsin and Pronase; other proteases tested were ineffective. When activated, the lectin agglutinated intestinal cells to which the parasite adheres in vivo. The lectin was most specific to mannose-6-phosphate and apparently was bound to the plasma membrane. Activation of a parasite lectin by a host protease represents a novel mechanism of host-parasite interaction and may contribute to the affinity of Giardia lamblia to the infection site.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lev, B -- Ward, H -- Keusch, G T -- Pereira, M E -- P-1-P30-AM 39428-01/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1986 Apr 4;232(4746):71-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3513312" target="_blank"〉PubMed〈/a〉

    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: Normal fibroblasts exposed to N-acetylmannosamine yielded lysosome-rich granular fractions loaded with free (unbound) sialic acid, whose velocity of egress increased with increasing initial loading. Fibroblast granular fractions of patients with Salla disease exhibited negligible egress of sialic acid, whether endogenous or derived from N-acetylmannosamine exposure. Salla disease represents the first disorder demonstrated to be caused by defective transport of a monosaccharide out of cellular lysosomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Renlund, M -- Tietze, F -- Gahl, W A -- New York, N.Y. -- Science. 1986 May 9;232(4751):759-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3961501" target="_blank"〉PubMed〈/a〉

    Description: Transgenic mice expressing a metallothionein-somatostatin fusion gene contain high concentrations of somatostatin in the anterior pituitary gland, a tissue that does not normally produce somatostatin. Immunoreactive somatostatin within the anterior pituitaries was found exclusively within gonadotrophs. Similarly, a metallothionein-human growth-hormone fusion gene was also expressed selectively in gonadotrophs. It is proposed that sequences common to the two fusion genes are responsible for the gonadotroph-specific expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Low, M J -- Lechan, R M -- Hammer, R E -- Brinster, R L -- Habener, J F -- Mandel, G -- Goodman, R H -- AM 01313/AM/NIADDK NIH HHS/ -- AM 30457/AM/NIADDK NIH HHS/ -- AM 31400/AM/NIADDK NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 Feb 28;231(4741):1002-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2868526" target="_blank"〉PubMed〈/a〉

    Description: Polyadenylated RNA isolated from senescent human diploid fibroblasts (HDF) inhibited DNA synthesis in proliferation-competent cells after microinjection, whereas polyadenylated RNA from young HDF had no inhibitory effect. Polyadenylated RNA from young cells made quiescent by removal of serum growth factors had a slight inhibitory effect on DNA synthesis. The abundance level of inhibitor messenger RNA (mRNA) from senescent cells was estimated at 0.8 and that of quiescent cells at 0.005 percent. These results demonstrate the existence of one or more antiproliferative mRNA's in nonproliferating normal human cells; these RNA's code for factors that either work antagonistically to initiators of DNA synthesis or regulate the expression of the initiators in some way. The abundance level of the inhibitory mRNA in senescent cells indicates the feasibility of developing a complementary DNA probe that will be useful in studying cell cycle control mechanisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lumpkin, C K Jr -- McClung, J K -- Pereira-Smith, O M -- Smith, J R -- AG-04749/AG/NIA NIH HHS/ -- AG-05333/AG/NIA NIH HHS/ -- T32-CA-09197/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 Apr 18;232(4748):393-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2421407" target="_blank"〉PubMed〈/a〉

    Description: The development of simultaneous resistance to multiple structurally unrelated drugs is a major impediment to cancer chemotherapy. Multidrug resistance in human KB carcinoma cells selected in colchicine, vinblastine, or Adriamycin is associated with amplification of specific DNA sequences (the multidrug resistance locus, mdr1). During colchicine selection resistance is initially accompanied by elevated expression of a 4.5-kilobase mdr1 messenger RNA (mRNA) without amplification of the corresponding genomic sequences. During selection for increased levels of resistance, expression of this mRNA is increased simultaneously with amplification of mdr1 DNA. Increased expression and amplification of mdr1 sequences were also found in multidrug-resistant sublines of human leukemia and ovarian carcinoma cells. These results suggest that increased expression of mdr1 mRNA is a common mechanism for multidrug resistance in human cells. Activation of the mdr1 gene by mutations or epigenetic changes may precede its amplification during the development of resistance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shen, D W -- Fojo, A -- Chin, J E -- Roninson, I B -- Richert, N -- Pastan, I -- Gottesman, M M -- New York, N.Y. -- Science. 1986 May 2;232(4750):643-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3457471" target="_blank"〉PubMed〈/a〉

    Description: Cleavage of phosphatidylinositol 4,5-bisphosphate by phospholipase C results in the production of two important second messengers: inositol-1,4,5-trisphosphate and 1,2-diacylglycerol. Although several receptors promote this cleavage, the molecular details of phospholipase C activation have remained unresolved. In this study, occupancy of a Ca2+-mobilizing receptor, the oligopeptide chemoattractant receptor on human polymorphonuclear leukocyte plasma membranes, was found to lead to the activation of a guanine nucleotide regulatory (N) protein by guanosine 5'-triphosphate. The activated N protein then stimulated a polyphosphoinositide-specific phospholipase C by reducing the Ca2+ requirement for expression of this activity from superphysiological to normal intracellular concentrations. Therefore, the N protein-mediated activation of phospholipase C may be a key step in the pathway of cellular activation by chemoattractants and certain other hormones.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, C D -- Cox, C C -- Snyderman, R -- 5PO1-CA-29589-04/CA/NCI NIH HHS/ -- 5RO1 DEO 3738-12/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 1986 Apr 4;232(4746):97-100.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3006254" target="_blank"〉PubMed〈/a〉

    Description: WIN 51711 and WIN 52084 are structurally related, antiviral compounds that inhibit the replication of rhino (common cold) viruses and related picornaviruses. They prevent the pH-mediated uncoating of the viral RNA. The compounds consist of a 3-methylisoxazole group that inserts itself into the hydrophobic interior of the VP1 beta-barrel, a connecting seven-membered aliphatic chain, and a 4-oxazolinylphenoxy group (OP) that covers the entrance to an ion channel in the floor of the "canyon." Viral disassembly may be inhibited by preventing the collapse of the VP1 hydrophobic pocket or by blocking the flow of ions into the virus interior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, T J -- Kremer, M J -- Luo, M -- Vriend, G -- Arnold, E -- Kamer, G -- Rossmann, M G -- McKinlay, M A -- Diana, G D -- Otto, M J -- New York, N.Y. -- Science. 1986 Sep 19;233(4770):1286-93.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3018924" target="_blank"〉PubMed〈/a〉

    Description: The genome of the human T-lymphotropic virus type III (HTLV-III/LAV) has the potential to encode at least three polypeptides in addition to those encoded by the gag, pol, and env genes. In this study, the product of the sor (short open reading frame) region, which overlaps the 3' end of the pol gene, was found to be a protein with a molecular weight of 23,000. An assay was developed for testing the ability of cloned HTLV-III proviruses to produce viruses cytopathic for T4+ lymphocytes. In the cell line used, C8166, neither the HTLV-III sor gene product nor the complete 3'-orf gene product were necessary for the replication or cytopathic effects of the HTLV-III.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sodroski, J -- Goh, W C -- Rosen, C -- Tartar, A -- Portetelle, D -- Burny, A -- Haseltine, W -- CA07580/CA/NCI NIH HHS/ -- CA40658/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 Mar 28;231(4745):1549-53.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3006244" target="_blank"〉PubMed〈/a〉

    Description: Experiments were conducted to isolate and characterize the gene and gene product of a human hematopoietic colony-stimulating factor with pluripotent biological activities. This factor has the ability to induce differentiation of a murine myelomonocytic leukemia cell line WEHI-3B(D+) and cells from patients with newly diagnosed acute nonlymphocytic leukemia (ANLL). A complementary DNA copy of the gene encoding a pluripotent human granulocyte colony-stimulating factor (hG-CSF) was cloned and expressed in Escherichia coli. The recombinant form of hG-CSF is capable of supporting neutrophil proliferation in a CFU-GM assay. In addition, recombinant hG-CSF can support early erythroid colonies and mixed colony formation. Competitive binding studies done with 125I-labeled hG-CSF and cell samples from two patients with newly diagnosed human leukemias as well as WEHI-3B(D+) cells showed that one of the human leukemias (ANLL, classified as M4) and the WEHI-3B(D+) cells have receptors for hG-CSF. Furthermore, the murine WEHI-3B(D+) cells and human leukemic cells classified as M2, M3, and M4 were induced by recombinant hG-CSF to undergo terminal differentiation to macrophages and granulocytes. The secreted form of the protein produced by the bladder carcinoma cell line 5637 was found to be O-glycosylated and to have a molecular weight of 19,600.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Souza, L M -- Boone, T C -- Gabrilove, J -- Lai, P H -- Zsebo, K M -- Murdock, D C -- Chazin, V R -- Bruszewski, J -- Lu, H -- Chen, K K -- CA00966/CA/NCI NIH HHS/ -- CA20194/CA/NCI NIH HHS/ -- CA32516/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 Apr 4;232(4746):61-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2420009" target="_blank"〉PubMed〈/a〉

    Description: Recombinant retroviruses containing the complete genomic human beta globin gene (under the control of its own promoter) and the bacterial neomycin phosphotransferase gene (under the control of the normal or enhancerless viral promoter) were used to derive transgenic mouse strains by infection of preimplantation embryos. Expression of the beta globin gene in hematopoietic tissues was observed in all transgenic strains. In addition, one strain showed ectopic expression of beta globin in the same tissues that also expressed high levels of RNA from the viral promoter. It is likely that expression from the long terminal repeat (LTR), in contrast to expression from the internal promoter, is dependent on the site of integration. Thus, retroviral vectors can be used for tissue-specific expression of foreign genes in transgenic mice, as well as for the identification of loci that allow developmental activation of a provirus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Soriano, P -- Cone, R D -- Mulligan, R C -- Jaenisch, R -- HD-19105/HD/NICHD NIH HHS/ -- P01-CA38497/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 Dec 12;234(4782):1409-13.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3024318" target="_blank"〉PubMed〈/a〉

    Description: T-cell receptors bind antigens only when the antigens are exposed on the cell surface. This can be studied best in the interaction of cytolytic T lymphocytes (CTL) with target cells because the recognition and binding event can be separated from the lytic phase. Studies with CTL clones specific for HLA-A2 and HLA-B7 demonstrated that conjugates of CTL's and target cells can be formed in the absence of specific antigen recognition. Furthermore, T-cell receptor and target antigen cannot interact unless there is conjugate formation. This indicates that nonspecific conjugate formation between CTL's and target cells precedes the recognition of specific antigen by the T-cell receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spits, H -- van Schooten, W -- Keizer, H -- van Seventer, G -- van de Rijn, M -- Terhorst, C -- de Vries, J E -- AI-15066/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1986 Apr 18;232(4748):403-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3485822" target="_blank"〉PubMed〈/a〉

    Description: When pulsed, ultraviolet laser radiation falls on the surface of an organic polymer or biological tissue, the material at the surface is spontaneously etched away to a depth of 0.1 to several micrometers. In the process, the depth of etching is controlled by the width of the pulse and the fluence of the laser, and there is no detectable thermal damage to the substrate. The material that is removed by etching consists of products ranging from atoms to small fragments of the polymer. They are ejected at supersonic velocities. This dry photoetching technique is useful in patterning polymer films. It is also under serious investigation in several areas in surgery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Srinivasan, R -- New York, N.Y. -- Science. 1986 Oct 31;234(4776):559-65.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3764428" target="_blank"〉PubMed〈/a〉

    Description: Comparison of HTLV-III, the putative AIDS virus, with other related viruses, may help to reveal more about the origin of AIDS in humans. In this study, the nucleotide sequence of the gag and pol genes of an equine infectious anemia virus (EIAV) proviral DNA clone was determined. The sequence was compared with that of HTLV-III and of visna, a pathogenic lentivirus of sheep. The results show that these viruses constitute a family clearly distinct from that of the type C viruses or the BLV-HTLV-I and -II group. Within the family, EIAV, HTLV-III, and visna appear to be equally divergent from a common evolutionary ancestor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stephens, R M -- Casey, J W -- Rice, N R -- N0I-C-23909/PHS HHS/ -- New York, N.Y. -- Science. 1986 Feb 7;231(4738):589-94.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3003905" target="_blank"〉PubMed〈/a〉

    Description: The protein product of oncogene c-myc is believed to be important in regulation of the cell cycle. However, its direct role in DNA synthesis has not been explored. Experiments presented here show that the addition of affinity-purified antibodies against the human c-myc protein to nuclei isolated from several types of human cells reversibly inhibited DNA synthesis and DNA polymerase activity of these nuclei. This suggests that c-myc encodes a protein that is functionally involved in DNA synthesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Studzinski, G P -- Brelvi, Z S -- Feldman, S C -- Watt, R A -- New York, N.Y. -- Science. 1986 Oct 24;234(4775):467-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3532322" target="_blank"〉PubMed〈/a〉

    Description: A direct measurement of the avidity of the junction between a cytotoxic T lymphocyte and its target cell was achieved by using a biophysical approach. A micromanipulation technique was used to determine the force required to separate a cytotoxic T cell (human clone F1, with specificity for HLA-DRw6) from its specific target cell (JY: HLA-A2, -B7, -DR4, w6) prior to delivery of the lethal hit. The force required to separate the F1-JY pair is 1.5 X 10(4) dynes per square centimeter. This junction avidity for F1-JY pairs is 6 to 13 times greater than that for F1-F1 and JY-JY pairs; the F1-JY conjugate requires a stronger separating force and is more easily rejoined than the homologous cell pairs. This study provides an estimate of the avidity of cytotoxic T cells for their target cells and insights into the biophysical correlates of the molecular complexes formed in the interaction of cytotoxic T cells and their targets during the cytotoxic process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sung, K L -- Sung, L A -- Crimmins, M -- Burakoff, S J -- Chien, S -- CA-13429/CA/NCI NIH HHS/ -- P01 HL 16851/HL/NHLBI NIH HHS/ -- R23 CA-37955/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 Dec 12;234(4782):1405-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3491426" target="_blank"〉PubMed〈/a〉

Efforts to isolate bases for these differences involved testing children on other achievement and cognitive tasks, interviewing mothers and teachers, and observing children in their classrooms. Cognitive abilities of children in the three countries are similar, but large differences exist in the children's life in school, the attitudes and beliefs of their mothers, and the involvement of both parents and children in schoolwork.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stevenson, H W -- Lee, S Y -- Stigler, J W -- MH 30567/MH/NIMH NIH HHS/ -- MH 33259/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1986 Feb 14;231(4739):693-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3945803" target="_blank"〉PubMed〈/a〉

    Description: Epstein-Barr virus (EBV), a ubiquitous human herpesvirus, has the ability to transform human B lymphocytes. No other cell type has been experimentally transformed by EBV, either by intact virions or naked viral DNA and subgenomic fragments. Two immortalized human T-lymphoblastoid cell lines have now been established by transfecting cord blood lymphocytes with purified B95-8 viral DNA enclosed in fusogenic Sendai virus envelopes (RSVE) and then exposing the cells to EBV from a P3HR-1 cell subclone. One of these lines, which has been fully characterized, is termed HBD-1. This line is positive for EBV DNA and expresses surface OKT11, OKT4, and Tac receptors, but not M-1, mu immunoglobulin chains, EBV receptors, or B-1 surface markers. The cells contain fully rearranged T-cell receptor genes and germline immunoglobulin genes. The karyotype of the cells is normal, they do not require interleukin-2 for growth, and do not contain human T-lymphotropic virus type I. However, the HBD-1 cells contain incomplete EBV genomes and express several EBV-determined antigens, including the early antigen type D, membrane antigens, but not EBV-determined nuclear antigen (EBNA). This association of the EBV genome with permanently growing hematopoietic cells of non B-cell lineage should prove useful in studies on the mechanism of EBV-mediated cell transformation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stevenson, M -- Volsky, B -- Hedenskog, M -- Volsky, D J -- CA33386/CA/NCI NIH HHS/ -- CA37465/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1986 Aug 29;233(4767):980-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3016899" target="_blank"〉PubMed〈/a〉

    Description: When isolated adult oligodendrocytes adhere to a substratum myelinogenesis occurs. Investigation of the mechanism by which this happens indicated that the oligodendrocyte-substratum interaction activated protein kinase C-dependent phosphorylation of myelin basic protein and promoted the synthesis of myelin basic protein. In addition, when agents that activate protein kinase C (second messenger diacylglycerol or a tumor-promoting phorbol ester) were added to nonattached oligodendrocytes, they mimicked the influence of the substratum by inducing phosphorylation of myelin basic protein; and reagents that increase cellular adenosine 3', 5'-monophosphate (cyclic AMP) inhibited phosphorylation of myelin basic protein. Thus, at least in vitro, the interaction between oligodendrocytes and the substratum may mediate myelinogenic events, and phosphorylation of myelin basic protein may be an early requirement in the sequence of steps that ultimately results in myelin formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vartanian, T -- Szuchet, S -- Dawson, G -- Campagnoni, A T -- GM-07183/GM/NIGMS NIH HHS/ -- HD-04583/HD/NICHD NIH HHS/ -- HD-06426/HD/NICHD NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1986 Dec 12;234(4782):1395-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2431483" target="_blank"〉PubMed〈/a〉

    Description: From the postwar high of 3.8 births per woman at the peak of the baby boom, the total fertility rate in the United States has fallen to 1.8, where it has remained unchanged for nearly a decade. This below-replacement level of fertility has, in recent decades, characterized most Western countries, some of which have shown declines to well below 1.5 births per woman. Were it not for the continued infusion of immigrants, the U.S. population, which already shows the aging characteristic of low fertility, would stop growing and begin to decline before the middle of the next century. The low fertility in the United States has been accomplished by a postponement of marriage and by the widespread use of contraception, with heavy reliance on surgical sterilization as a contraceptive method. Judging from the experience of other Western countries and from our own historical experience of two centuries of fertility decline interrupted only by the baby boom, as well as from the absence of social trends that would counteract those contributing to that decline, the prognosis is for a continued low level of fertility in the United States.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Westoff, C F -- New York, N.Y. -- Science. 1986 Oct 31;234(4776):554-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3532324" target="_blank"〉PubMed〈/a〉

    Description: Pf 155, a protein of the human malaria parasite Plasmodium falciparum, is strongly immunogenic in humans and is believed to be a prime candidate for the preparation of a vaccine. Human monoclonal antibodies to Pf 155 were obtained by cloning B cells that had been prepared from an immune donor and transformed with Epstein-Barr virus. When examined by indirect immunofluorescence, these antibodies stained the surface of infected erythrocytes, free merozoites, segmented schizonts, and gametocytes. They bound to a major polypeptide with a relative molecular weight of 155K and to two minor ones (135K and 120K), all having high affinity for human glycophorin. The antibodies strongly inhibited merozoite reinvasion in vitro, suggesting that they might be appropriate reagents for therapeutic administration in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Udomsangpetch, R -- Lundgren, K -- Berzins, K -- Wahlin, B -- Perlmann, H -- Troye-Blomberg, M -- Carlsson, J -- Wahlgren, M -- Perlmann, P -- Bjorkman, A -- New York, N.Y. -- Science. 1986 Jan 3;231(4733):57-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3510452" target="_blank"〉PubMed〈/a〉

    Description: The relationship of the copy numbers of the c-myc and N-myc oncogenes to tumor formation and progression was studied in small cell carcinoma of the lung. When 96 neoplastic lesions from 45 patients were examined, these lesions could be grouped into three categories: high copy (tumors with greater than 3 copies of the N-myc or c-myc gene per haploid genome), middle copy (1.5 to 3 copies per genome), and normal copy. Fourteen of the patients had middle copy tumors, but this was almost always a result of chromosome duplication rather than the amplification of a small genetic locus. In contrast, five patients had high copy tumors, with the increased copy number in each case due to gene amplification. The amplification did not occur in a heterogeneous fashion within individual patients, since all metastatic lesions from patients with high copy lung tumors were also high copy, while none of 41 metastatic lesions from the other patients were high copy. These data suggest that gene amplification is an important step in neoplastic growth in a subset of patients with small cell carcinoma of the lung and that this genetic event occurs relatively early (before metastasis) in this subset.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wong, A J -- Ruppert, J M -- Eggleston, J -- Hamilton, S R -- Baylin, S B -- Vogelstein, B -- CA-09243/CA/NCI NIH HHS/ -- GM-31676/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Jul 25;233(4762):461-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3014659" target="_blank"〉PubMed〈/a〉

    Description: The Watanabe heritable hyperlipidemic (WHHL) rabbit, an animal with familial hypercholesterolemia, produces a mutant receptor for plasma low-density lipoprotein (LDL) that is not transported to the cell surface at a normal rate. Cloning and sequencing of complementary DNA's from normal and WHHL rabbits, shows that this defect arises from an in-frame deletion of 12 nucleotides that eliminates four amino acids from the cysteine-rich ligand binding domain of the LDL receptor. A similar mutation, detected by S1 nuclease mapping of LDL receptor messenger RNA, occurred in a patient with familial hypercholesterolemia whose receptor also fails to be transported to the cell surface. These findings suggest that animal cells may have fail-safe mechanisms that prevent the surface expression of improperly folded proteins with unpaired or improperly bonded cysteine residues.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4451858/" 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/PMC4451858/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamamoto, T -- Bishop, R W -- Brown, M S -- Goldstein, J L -- Russell, D W -- HL 01287/HL/NHLBI NIH HHS/ -- HL 20948/HL/NHLBI NIH HHS/ -- HL 31346/HL/NHLBI NIH HHS/ -- P01 HL020948/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1986 Jun 6;232(4755):1230-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3010466" target="_blank"〉PubMed〈/a〉

    Description: Antigenic or mitogenic stimulation of T cells induces the secretion of an array of protein hormones that regulate immune responses. Molecular cloning has contributed strongly to our present understanding of the nature of this regulation. A complementary DNA (cDNA) library prepared from a cloned concanavalin A-activated mouse T-helper cell line was screened for abundant and induction-specific cDNA's. One such randomly chosen cDNA was found to encode mouse preproenkephalin messenger RNA (mRNA). Preproenkephalin mRNA represented about 0.4 percent of the mRNA in the activated cell line but was absent in resting cells of this line.

    Description: Survey questions often probe respondents for quantitative facts about events in their past: "During the last 2 weeks, on days when you drank liquor, about how many drinks did you have?" "During the past 12 months, how many visits did you make to a dentist?" "When did you last work at a full-time job?" are all examples from national surveys. Although questions like these make an implicit demand to remember and enumerate specific autobiographical episodes, respondents frequently have trouble complying because of limits on their ability to recall. In these situations, respondents resort to inferences that use partial information from memory to construct a numeric answer. Results from cognitive psychology can be useful in understanding and investigating these phenomena. In particular, cognitive research can help in identifying situations that inhibit or facilitate recall and can reveal inferences that affect the accuracy of respondents' answers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bradburn, N M -- Rips, L J -- Shevell, S K -- New York, N.Y. -- Science. 1987 Apr 10;236(4798):157-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3563494" target="_blank"〉PubMed〈/a〉

Consequently, human resource issues present an unprecedented challenge in the nation's quest to achieve a fully employed and equitable society.

    Description: The alpha-chain of the nicotinic acetylcholine receptor carries the binding sites both for cholinergic ligands and for most experimentally induced or naturally occurring antibodies to the native receptor. By means of expression cloning in Escherichia coli, fusion proteins were derived from specific fragments of a complementary DNA encoding the mouse alpha-chain, allowing the mapping of the toxin-binding site to residues 160-216 and the main immunogenic region to residues 6-85. This approach permits the independent study of different functional domains of a complex receptor molecule and should be generally applicable to other proteins for which complementary DNA clones are available.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barkas, T -- Mauron, A -- Roth, B -- Alliod, C -- Tzartos, S J -- Ballivet, M -- New York, N.Y. -- Science. 1987 Jan 2;235(4784):77-80.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2432658" target="_blank"〉PubMed〈/a〉

    Description: Deletions of the long arm of chromosome 6 (6q-) are frequently found in hematopoietic neoplasms, including acute lymphoblastic leukemias, non-Hodgkin lymphomas and (less frequently) myeloid leukemias. The c-myb proto-oncogene has been mapped to region 6q21-24, which suggests that it could be involved in the 6q- aberrations. By means of in situ chromosomal hybridization on cells from six hematopoietic malignancies, it was demonstrated that the c-myb locus is not deleted, but is retained on band q22, which is consistently bordered by the chromosomal breakpoints in both interstitial and terminal 6q- deletions. The deletion breakpoints were located at some distance from the myb locus since no rearrangement of c-myb sequences was found. In one case, however, amplification of the entire c-myb locus was detectable. Furthermore, in all cases tested that carry 6q- deletions, myb messenger RNA levels were significantly higher than in normal cells or in malignant cells matched for lineage and stage of differentiation but lacking the 6q- marker. These results indicate that 6q- deletions are accompanied by structural and functional alterations of the c-myb locus and that these alterations may be involved in the pathogenesis of leukemias and lymphomas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barletta, C -- Pelicci, P G -- Kenyon, L C -- Smith, S D -- Dalla-Favera, R -- CA16239/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1987 Feb 27;235(4792):1064-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3469751" target="_blank"〉PubMed〈/a〉

    Description: Among the major parasitic infections, schistosomiasis may be the most promising candidate for human vaccination. Information about mechanisms of immunity, gained mainly from experimental models but likely to be relevant to human infection, indicates a dynamic balance between protective and regulatory (blocking) mechanisms. Besides cell-mediated responses leading to macrophage activation, antibody-dependent cell-mediated cytotoxicity systems involving precise antibody isotypes and nonlymphoid cells (mononuclear phagocytes, eosinophils, and platelets) appear to be essential effectors of immune attack. The slow development of immunity in humans seems related to the production of antibodies that cross-react with schistosomulum surface antigen and block the binding of antibodies of the effector isotype. Schistosomes that survive in the bloodstream and produce chronic infections may evade the immune system as a result of intrinsic changes in membrane susceptibility and of transient expression of target antigens; at other stages of the parasite life cycle, cross-reactive molecules may be secreted that play an essential role in the induction of immunity. Several schistosome proteins have been characterized as candidates for vaccination. Among these, an antigen of 28 kilodaltons has been cloned and shown to be immunogenic in humans and protective in mice, rats, and baboons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Capron, A -- Dessaint, J P -- Capron, M -- Ouma, J H -- Butterworth, A E -- New York, N.Y. -- Science. 1987 Nov 20;238(4830):1065-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre d'Immunologie et de Biologie Parasitaire, Unite Mixte INSERM 167-CNRS 624, Institut Pasteur, Lille, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3317823" target="_blank"〉PubMed〈/a〉

    Description: B lymphocytes bearing the Leu-1 cell-surface antigen (Leu-1+), the human equivalent of mouse Ly-1+ B lymphocytes, have been detected in human peripheral blood, but there is little information on their frequency and properties. Analysis by fluorescence-activated cell sorter and double immunofluorescence showed that Leu-1+ B cells are consistently present in the peripheral blood and spleens of healthy subjects and constitute 17.0 +/- 5.0% (mean value +/- standard deviation) and 17.3 +/- 3.9%, respectively, of total B cells. When purified Leu-1+ and Leu-1- B lymphocytes were transformed into immunoglobulin-secreting cells by infection with Epstein-Barr virus and the culture fluids were tested for reactivity with self-antigens, at least two important autoantibodies, antibody to the Fc fragment of human immunoglobulin G (rheumatoid factor) and antibody to single-stranded DNA, were found to be made exclusively by Leu-1+ B cells. It is concluded that the Leu-1+ lymphocytes represent a major subset of the normal human B cell repertoire and include the B cells capable of making autoantibodies similar to those found in systemic lupus erythematosus and rheumatoid arthritis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Casali, P -- Burastero, S E -- Nakamura, M -- Inghirami, G -- Notkins, A L -- New York, N.Y. -- Science. 1987 Apr 3;236(4797):77-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3105056" target="_blank"〉PubMed〈/a〉

    Description: Myotonic muscular dystrophy (DM) is the most common muscular dystrophy, affecting adults as well as children. It is inherited as an autosomal dominant trait and is characterized by variable expressivity and late age-of-onset. Linkage studies have established the locus on chromosome 19. In order to identify tightly linked probes for diagnosis as well as to define in detail the DM gene region, chromosome 19 libraries were constructed and screened for restriction fragment length polymorphisms tightly linked to DM. A genomic clone, LDR152 (D19S19), was isolated that is tightly linked to DM; recombination fraction = 0.0 (95% confidence limits 0.0-0.03); lod score, 15.4.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bartlett, R J -- Pericak-Vance, M A -- Yamaoka, L -- Gilbert, J -- Herbstreith, M -- Hung, W Y -- Lee, J E -- Mohandas, T -- Bruns, G -- Laberge, C -- NS19999/NS/NINDS NIH HHS/ -- RR-30/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1987 Mar 27;235(4796):1648-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3029876" target="_blank"〉PubMed〈/a〉

    Description: Exposure to bacterial endotoxins has long been known to stimulate the release of anterior pituitary hormones; administration of endotoxin was at one time a common clinical test of anterior pituitary function. Endotoxin is a potent stimulus for production of the endogenous pyrogenic protein, interleukin-1 (IL-1), by macrophages and monocytes. The possibility that IL-1 has a direct effect on the secretion of hormones by rat pituitary cells in a monolayer culture was investigated. Recombinant human IL-1 beta stimulated the secretion of adrenocorticotropic hormone, luteinizing hormone, growth hormone, and thyroid-stimulating hormone. Increased hormone secretion into culture supernatants was found with IL-1 concentrations ranging from 10(-9) M to 10(-12) M. Prolactin secretion by the monolayers was inhibited by similar doses. These concentrations of IL-1 are within the range reported for IL-1 in serum, suggesting that IL-1 generated peripherally by mononuclear immune cells may act directly on anterior pituitary cells to modulate hormone secretion in vivo. Incubation of IL-1 solutions with antibody to IL-1 neutralized these actions. These pituitary effects of IL-1 suggest that this monokine may be an important regulator of the metabolic adaptations to infectious stressors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bernton, E W -- Beach, J E -- Holaday, J W -- Smallridge, R C -- Fein, H G -- New York, N.Y. -- Science. 1987 Oct 23;238(4826):519-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neuropsychiatry, Walter Reed Army Institute of Research, Washington, D.C. 20307-5100.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2821620" target="_blank"〉PubMed〈/a〉

    Description: Tandem mass spectrometry can be used to solve a number of protein structural problems that are not amenable to conventional methods for amino acid sequencing. Typical problems that use this approach involve characterization of peptides with blocked amino termini or peptides that have been otherwise posttranslationally processed, such as, by phosphorylation or sulfation. The structure and homogeneity of synthetic peptides can also be evaluated. Since peptides can be selectively characterized in the presence of other peptides or contaminants, the need for extensive purification is reduced or eliminated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Biemann, K -- Scoble, H A -- GM05472/GM/NIGMS NIH HHS/ -- RR00317/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1987 Aug 28;237(4818):992-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3303336" target="_blank"〉PubMed〈/a〉

    Description: The c-erbA gene belongs to a multigene family that encodes transcriptional regulatory proteins including the v-erbA oncogene product, steroid hormone receptors, and the vitamin D3 receptor. A v-erbA DNA probe encoding the DNA-binding region of the v-erbA protein was used to screen a human complementary DNA testis library. One of the clones isolated, erbA-T-1, was found to encode a 490-amino acid protein (erbA-T). The erbA-T polypeptide shows high homology with the proteins encoded by both the chicken c-erbA and the human c-erbA-beta genes but is most closely related to the chicken gene. The chicken c-erbA and the human c-erbA-beta genes encode high-affinity receptors for thyroid hormone, and here it is shown that the erbA-T protein binds specifically to 3,5,3'-triiodo-L-thyronine with a dissociation constant of 3.8 +/- 0.2 x 10(-10) M. These data imply that more than one thyroid hormone receptor exists in humans and that these receptors might have different tissue- and gene-activating specificities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benbrook, D -- Pfahl, M -- DK-35083/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1987 Nov 6;238(4828):788-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Research Center, La Jolla Cancer Research Foundation, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3672126" target="_blank"〉PubMed〈/a〉

    Description: Ribonuclease mitochondrial RNA processing, a site-specific endoribonuclease involved in primer RNA metabolism in mammalian mitochondria, requires an RNA component for its activity. On the basis of copurification and selective inactivation with complementary oligonucleotides, a 135-nucleotide RNA species, not encoded in the mitochondrial genome, is identified as the RNA moiety of the endoribonuclease. This finding implies transport of a nucleus-encoded RNA, essential for organelle DNA replication, to the mitochondrial matrix.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, D D -- Clayton, D A -- GM-33088-16/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1987 Mar 6;235(4793):1178-84.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2434997" target="_blank"〉PubMed〈/a〉

    Description: Li-Fraumeni syndrome is manifested in a variety of neoplasms that are transmitted in a dominantly inherited pattern. The noncancerous skin fibroblasts of family members exhibit a unique characteristic of being resistant to the killing effect of ionizing radiation. A three- to eightfold elevation in expression of c-myc and an apparent activation of c-raf-1 gene have been observed in these noncancerous skin fibroblasts. These results may provide insight into the heritable defect underlying the familial predisposition to a variety of cancers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, E H -- Pirollo, K F -- Zou, Z Q -- Cheung, H Y -- Lawler, E L -- Garner, R -- White, E -- Bernstein, W B -- Fraumeni, J W Jr -- Blattner, W A -- CA45158/CA/NCI NIH HHS/ -- CO7488/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1987 Aug 28;237(4818):1036-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3616624" target="_blank"〉PubMed〈/a〉

    Description: A group of proteins anchored to the cell by phosphatidylinositol (PI) has recently been identified. The significance of this new class of membrane anchor is unknown; one possibility is that it facilitates release of the molecule by phospholipases. In fact, phospholipase C enzymes specific for the complex carboxyl-terminal glycolipids of these proteins have been isolated from African trypanosomes and from hepatocyte plasma membranes. This study reports the discovery of a glycan-PI-specific phospholipase D in human serum that cleaves both the membrane form of the variant surface glycoprotein of African trypanosomes and its glycolipid precursor, but not phosphatidylethanolamine, phosphatidylcholine, or phosphatidylinositol. Decay-accelerating factor, another PI-anchored molecule, is also cleaved by the enzyme and converted from a hydrophobic to a soluble protein. The enzyme is Ca2+-dependent, heat labile, and not affected by the inhibitor of serine proteases, phenylmethylsulfonylfluoride. Its function is not known, but the present findings indicate that it participates in the metabolism of glycolipid-anchored membrane proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davitz, M A -- Hereld, D -- Shak, S -- Krakow, J -- Englund, P T -- Nussenzweig, V -- 1-ES00136/ES/NIEHS NIH HHS/ -- GM7309/GM/NIGMS NIH HHS/ -- HL-00650/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1987 Oct 2;238(4823):81-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, New York University School of Medicine, NY 10016.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2443973" target="_blank"〉PubMed〈/a〉

    Description: A wide variety of human tumors contain an amplified or overexpressed erbB-2 gene, which encodes a growth factor receptor-like protein. When erbB-2 complementary DNA was expressed in NIH/3T3 cells under the control of the SV40 promoter, the gene lacked transforming activity despite expression of detectable levels of the erbB-2 protein. A further five- to tenfold increase in its expression under influence of the long terminal repeat of Moloney murine leukemia virus was associated with activation of erbB-2 as a potent oncogene. The high levels of the erbB-2 product associated with malignant transformation of NIH/3T3 cells were observed in human mammary tumor cells that overexpressed this gene. These findings demonstrate a new mechanism for acquisition of oncogenic properties by genes encoding growth factor receptor-like proteins and provide a functional basis for the role of their overexpression in the development of human malignancies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Di Fiore, P P -- Pierce, J H -- Kraus, M H -- Segatto, O -- King, C R -- Aaronson, S A -- New York, N.Y. -- Science. 1987 Jul 10;237(4811):178-82.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2885917" target="_blank"〉PubMed〈/a〉

    Description: Apparent motion was used to explore humans' ability to perceive the direction of motion in the visual field. A marked qualitative difference in this ability was found between short- and long-range motion. For short-range motion, the detection of the direction of motion is characterized by parallel operation over a wide visual field (that is, detection performance is independent of the number of objects in an array). When the positional displacement is large relative to an object's size, the direction of motion is detected in a serial manner. The process of detection is limited in this case by the ability to detect other events, such as appearance and disappearance of an object, and the ability to compute their spatio-temporal relations. The results are consistent with a previously suggested division of the motion detection system into short- and long-range processes. The direction of short-range motion can be perceived in parallel (preattentively), whereas long-range motion is attentive and requires more complicated computations. It seems that the detection of long-range motion is a conjunction task, combining the detection of disappearance and appearance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dick, M -- Ullman, S -- Sagi, D -- New York, N.Y. -- Science. 1987 Jul 24;237(4813):400-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3603025" target="_blank"〉PubMed〈/a〉

    Description: Although certain gold [Au(I)] compounds have been used effectively in the treatment of rheumatoid arthritis for some years, the molecular basis for such therapeutic action has been unclear. One possible mechanism of the action of Au(I) compounds is that they protect unsaturated membrane lipids and proteins against oxidative degradation caused by activated phagocytes that are not properly regulated. In this study it has been shown that superoxide ion (O-2.), a product of activated phagocytes, can be oxidized to electronically excited singlet oxygen (O1(2)delta g), an agent that is capable of peroxidation of unsaturated fatty acid derivatives. It has also been shown that antiarthritic Au(I) compounds are effective deactivators of O1(2)delta g with quenching constants on the order of 10(7) M-1 sec-1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Corey, E J -- Mehrotra, M M -- Khan, A U -- New York, N.Y. -- Science. 1987 Apr 3;236(4797):68-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3563489" target="_blank"〉PubMed〈/a〉

    Description: Many mutations leading to human disease are the result of single DNA base pair changes that cannot be identified by Southern analysis. This has prompted the development of alternative assays for point mutation detection. The recently described ribonuclease A cleavage procedure, with a polyuridylic acid-paper affinity chromatography step, has been used to identify the mutational lesions in the hypoxanthine phosphoribosyltransferase (HPRT) messenger RNAs of patients with Lesch-Nyhan syndrome. Distinctive ribonuclease A cleavage patterns were identified in messenger RNA from 5 of 14 Lesch-Nyhan patients who were chosen because no HPRT Southern or Northern blotting pattern changes had been found. This approach now allows HPRT mutation detection in 50 percent of the cases of Lesch-Nyhan syndrome. The polyuridylic acid-paper affinity procedure provides a general method for analysis of low abundance messenger RNAs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gibbs, R A -- Caskey, C T -- New York, N.Y. -- Science. 1987 Apr 17;236(4799):303-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3563511" target="_blank"〉PubMed〈/a〉

    Description: An abnormal alpha 2-antiplasmin that is associated with a serious bleeding tendency has been found in a Dutch family and is referred to as alpha 2-antiplasmin Enschede. This abnormal alpha 2-antiplasmin is converted from an inhibitor of plasmin to a substrate. The molecular defect of alpha 2-antiplasmin Enschede, as revealed by sequencing of cloned genomic DNA fragments, consists of an alanine insertion near the active site region of the molecule. Substitution of this fragment into complementary DNA for a wild-type alpha 2-antiplasmin yields a translation product with physical and functional properties typical of the abnormal alpha 2-antiplasmin Enschede. The naturally occurring mutant may serve as a model for investigating the structures that determine the properties of an inhibitor versus those of a substrate in serine protease inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Holmes, W E -- Lijnen, H R -- Nelles, L -- Kluft, C -- Nieuwenhuis, H K -- Rijken, D C -- Collen, D -- New York, N.Y. -- Science. 1987 Oct 9;238(4824):209-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Thrombosis and Vascular Research, University of Leuven, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2958938" target="_blank"〉PubMed〈/a〉

    Description: A human B cell subpopulation identifiable by the expression of the cell surface antigen Leu-1 (CD5) is responsible for most of the immunoglobulin M rheumatoid factor secreted in vitro after the cells are stimulated with Staphylococcus aureus. The ability of B cells bearing the Leu-1 marker (Leu-1+) to secrete rheumatoid factor is present early in development and extends to adulthood, since Leu-1+ B cells from cord blood and from peripheral blood lymphocytes of both normal adults and patients with certain autoimmune conditions secrete rheumatoid factor in comparable amounts. The neonatal enrichment of Leu-1+ B cells, the presence of Leu-1+ B cells in increased frequencies in patients with autoimmune disease, and the involvement of Leu-1+ B cells in autoantibody secretion suggest both developmental and functional homologies between this human B cell subpopulation and the murine Ly-1 B cell subpopulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hardy, R R -- Hayakawa, K -- Shimizu, M -- Yamasaki, K -- Kishimoto, T -- New York, N.Y. -- Science. 1987 Apr 3;236(4797):81-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3105057" target="_blank"〉PubMed〈/a〉

    Description: Growth factors and their receptors are involved in the regulation of cell proliferation and also play a key role in oncogenesis. In this study, a novel putative kinase receptor gene, termed eph, has been identified and characterized by molecular cloning. Its primary structure is similar to that of tyrosine kinase receptors thus far cloned and includes a cysteine-rich region in the extracellular domain. However, other features of the sequence distinguish the eph gene product from known receptors with tyrosine kinase activity. Thus the eph protein may define a new class of these molecules. The eph gene is overexpressed in several human carcinomas, suggesting that this gene may be involved in the neoplastic process of some tumors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hirai, H -- Maru, Y -- Hagiwara, K -- Nishida, J -- Takaku, F -- New York, N.Y. -- Science. 1987 Dec 18;238(4834):1717-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Third Department of Internal Medicine, Faculty of Medicine, University of Tokyo, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2825356" target="_blank"〉PubMed〈/a〉
