    Notes: Summary Five generations of divergent selection for plasma concentration of insulin-like growth factor-1 (IGF-1) and for 12-week body weight were carried out in mice, including randomly selected control lines for each trait. All lines were replicated once (12 lines in total). Each replicate line consisted of eight male and eight female parents per generation. Litter size was standardized to eight pups at birth. Mass selection was applied in the selected lines and within-family random selection in the control lines. Blood was taken from the orbital sinus of individual mice at 12 weeks of age for IGF-1 assay. Realized heritabilities were 0.10±0.01 for IGF-1 and 0.41 ± 0.02 for 12-week weight. The realized genetic correlation between IGF-1 and 12-week weight was 0.58 ± 0.01, with a phenotypic correlation of 0.38. Although the genetic correlation between IGF-1 and body weight in mice is moderately positive, 12-week weight responded 3.5 times as fast to weight selection as to selection for IGF-1.

    Mapping of DNA instability at the fragile X to a trinucleotide repeat sequence p(CCG)n (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-06-21
    Description: The sequence of a Pst I restriction fragment was determined that demonstrate instability in fragile X syndrome pedigrees. The region of instability was localized to a trinucleotide repeat p(CCG)n. The sequence flanking this repeat were identical in normal and affected individuals. The breakpoints in two somatic cell hybrids constructed to break at the fragile site also mapped to this repeat sequence. The repeat exhibits instability both when cloned in a nonhomologous host and after amplification by the polymerase chain reaction. These results suggest variation in the trinucleotide repeat copy number as the molecular basis for the instability and possibly the fragile site. This would account for the observed properties of this region in vivo and in vitro.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kremer, E J -- Pritchard, M -- Lynch, M -- Yu, S -- Holman, K -- Baker, E -- Warren, S T -- Schlessinger, D -- Sutherland, G R -- Richards, R I -- New York, N.Y. -- Science. 1991 Jun 21;252(5013):1711-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cytogenetics and Molecular Genetics, Adelaide Children's Hospital, South Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1675488" target="_blank"〉PubMed〈/a〉

    A multifunctional aqueous channel formed by CFTR (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-11-27
    Description: The cystic fibrosis gene product (CFTR) is a complex protein that functions as an adenosine 3,5-monophosphate (cAMP)-stimulated ion channel and possibly as a regulator of intracellular processes. In order to determine whether the CFTR molecule contains a functional aqueous pathway, anion, water, and urea transport were measured in Xenopus oocytes expressing CFTR. Cyclic AMP agonists induced a Cl- conductance of 94 microsiemens and an increase in water permeability of 4 x 10(-4) centimeter per second that was inhibited by a Cl- channel blocker and was dependent on anion composition. CFTR has a calculated single channel water conductance of 9 x 10(-13) cubic centimeter per second, suggesting a pore-like aqueous pathway. Oocytes expressing CFTR also showed cAMP-stimulated transport of urea but not the larger solute sucrose. Thus CFTR contains a cAMP-stimulated aqueous pore that can transport anions, water, and small solutes. The results also provide functional evidence for water movement through an ion channel.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hasegawa, H -- Skach, W -- Baker, O -- Calayag, M C -- Lingappa, V -- Verkman, A S -- DK35124/DK/NIDDK NIH HHS/ -- DK43840/DK/NIDDK NIH HHS/ -- HL42368/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1992 Nov 27;258(5087):1477-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of California, San Francisco 94143-0532.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1279809" target="_blank"〉PubMed〈/a〉

    Spacing differentiation in the developing Drosophila eye: a fibrinogen-related lateral inhibitor encoded by scabrous (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-12-07
    Description: In the development of multicellular organisms a diversity of cell types differentiate at specific positions. Spacing patterns, in which an array of two or more cell types forms from a uniform field of cells, are a common feature of development. Identical precursor cells may adopt different fates because of competition and inhibition between them. Such a pattern in the developing Drosophila eye is the evenly spaced array of R8 cells, around which other cell types are subsequently recruited. Genetic studies suggest that the scabrous mutation disrupts a signal produced by R8 cells that inhibits other cells from also becoming R8 cells. The scabrous locus was cloned, and it appears to encode a secreted protein partly related to the beta and gamma chains of fibrinogen. It is proposed that the sca locus encodes a lateral inhibitor of R8 differentiation. The roles of the Drosophila EGF-receptor homologue (DER) and Notch genes in this process were also investigated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baker, N E -- Mlodzik, M -- Rubin, G M -- New York, N.Y. -- Science. 1990 Dec 7;250(4986):1370-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2175046" target="_blank"〉PubMed〈/a〉

    K+ current diversity is produced by an extended gene family conserved in Drosophila and mouse (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-05-04
    Description: The Drosophila Shaker gene on the X chromosome has three sister genes, Shal, Shab, and Shaw, which map to the second and third chromosomes. This extended gene family encodes voltage-gated potassium channels with widely varying kinetics (rate of macroscopic current activation and inactivation) and voltage sensitivity of steady-state inactivation. The differences in the currents of the various gene products are greater than the differences produced by alternative splicing of the Shaker gene. In Drosophila, the transient (A current) subtype of the potassium channel (Shaker and Shal) and the delayed-rectifier subtype (Shab and Shaw) are encoded by homologous genes, and there is more than one gene for each subtype of channel. Homologs of Shaker, Shal, Shab, and Shaw are present in mammals; each Drosophila potassium-channel gene may be represented as a multigene subfamily in mammals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wei, A -- Covarrubias, M -- Butler, A -- Baker, K -- Pak, M -- Salkoff, L -- 1 RO1-NS24785-01/NS/NINDS NIH HHS/ -- GMO 7200/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 May 4;248(4955):599-603.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Neurobiology, Washington University School of Medicine, St. Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2333511" target="_blank"〉PubMed〈/a〉

    Treatment of established renal cancer by tumor cells engineered to secrete interleukin-4 (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-11-01
    Description: The generation of antigen-specific antitumor immunity is the ultimate goal in cancer immunotherapy. When cells from a spontaneously arising murine renal cell tumor were engineered to secrete large doses of interleukin-4 (IL-4) locally, they were rejected in a predominantly T cell-independent manner. However, animals that rejected the IL-4-transfected tumors developed T cell-dependent systemic immunity to the parental tumor. This systemic immunity was tumor-specific and primarily mediated by CD8+ T cells. Established parental tumors could be cured by the systemic immune response generated by injection of the genetically engineered tumors. These results provide a rationale for the use of lymphokine gene-transfected tumor cells as a modality for cancer therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Golumbek, P T -- Lazenby, A J -- Levitsky, H I -- Jaffee, L M -- Karasuyama, H -- Baker, M -- Pardoll, D M -- New York, N.Y. -- Science. 1991 Nov 1;254(5032):713-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Johns Hopkins University, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1948050" target="_blank"〉PubMed〈/a〉

    Design of a novel globular protein fold with atomic-level accuracy (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-11-25
    Description: A major challenge of computational protein design is the creation of novel proteins with arbitrarily chosen three-dimensional structures. Here, we used a general computational strategy that iterates between sequence design and structure prediction to design a 93-residue alpha/beta protein called Top7 with a novel sequence and topology. Top7 was found experimentally to be folded and extremely stable, and the x-ray crystal structure of Top7 is similar (root mean square deviation equals 1.2 angstroms) to the design model. The ability to design a new protein fold makes possible the exploration of the large regions of the protein universe not yet observed in nature.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuhlman, Brian -- Dantas, Gautam -- Ireton, Gregory C -- Varani, Gabriele -- Stoddard, Barry L -- Baker, David -- New York, N.Y. -- Science. 2003 Nov 21;302(5649):1364-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14631033" target="_blank"〉PubMed〈/a〉

    Prevention of organ allograft rejection by a specific Janus kinase 3 inhibitor (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-11-01
    Description: Because of its requirement for signaling by multiple cytokines, Janus kinase 3 (JAK3) is an excellent target for clinical immunosuppression. We report the development of a specific, orally active inhibitor of JAK3, CP-690,550, that significantly prolonged survival in a murine model of heart transplantation and in cynomolgus monkeys receiving kidney transplants. CP-690,550 treatment was not associated with hypertension, hyperlipidemia, or lymphoproliferative disease. On the basis of these preclinical results, we believe JAK3 blockade by CP-690,550 has potential for therapeutically desirable immunosuppression in human organ transplantation and in other clinical settings.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Changelian, Paul S -- Flanagan, Mark E -- Ball, Douglas J -- Kent, Craig R -- Magnuson, Kelly S -- Martin, William H -- Rizzuti, Bonnie J -- Sawyer, Perry S -- Perry, Bret D -- Brissette, William H -- McCurdy, Sandra P -- Kudlacz, Elizabeth M -- Conklyn, Maryrose J -- Elliott, Eileen A -- Koslov, Erika R -- Fisher, Michael B -- Strelevitz, Timothy J -- Yoon, Kwansik -- Whipple, David A -- Sun, Jianmin -- Munchhof, Michael J -- Doty, John L -- Casavant, Jeffrey M -- Blumenkopf, Todd A -- Hines, Michael -- Brown, Matthew F -- Lillie, Brett M -- Subramanyam, Chakrapani -- Shang-Poa, Chang -- Milici, Anthony J -- Beckius, Gretchen E -- Moyer, James D -- Su, Chunyan -- Woodworth, Thasia G -- Gaweco, Anderson S -- Beals, Chan R -- Littman, Bruce H -- Fisher, Douglas A -- Smith, James F -- Zagouras, Panayiotis -- Magna, Holly A -- Saltarelli, Mary J -- Johnson, Kimberly S -- Nelms, Linda F -- Des Etages, Shelley G -- Hayes, Lisa S -- Kawabata, Thomas T -- Finco-Kent, Deborah -- Baker, Deanna L -- Larson, Michael -- Si, Ming-Sing -- Paniagua, Ricardo -- Higgins, John -- Holm, Bari -- Reitz, Bruce -- Zhou, Yong-Jie -- Morris, Randall E -- O'Shea, John J -- Borie, Dominic C -- New York, N.Y. -- Science. 2003 Oct 31;302(5646):875-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Immunology Group, Department of Antibacterials and Immunology, Pfizer Global Researchand Development, Groton, CT 06340, USA. paul_s_changelian@groton.pfizer.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14593182" target="_blank"〉PubMed〈/a〉

    Relation of phenotype evolution of HIV-1 to envelope V2 configuration (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-06-04
    Description: Biological variability of human immunodeficiency virus type-1 (HIV-1) is involved in the pathogenesis of acquired immunodeficiency syndrome (AIDS). Syncytium-inducing (SI) HIV-1 variants emerge in 50 percent of infected individuals during infection, preceding accelerated CD4+ T cell loss and rapid progression to AIDS. The V1 to V2 and V3 region of the viral envelope glycoprotein gp120 contained the major determinants of SI capacity. The configuration of a hypervariable locus in the V2 domain appeared to be predictive for non-SI to SI phenotype conversion. Early prediction of HIV-1 phenotype evolution may be useful for clinical monitoring and treatment of asymptomatic infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Groenink, M -- Fouchier, R A -- Broersen, S -- Baker, C H -- Koot, M -- van't Wout, A B -- Huisman, H G -- Miedema, F -- Tersmette, M -- Schuitemaker, H -- New York, N.Y. -- Science. 1993 Jun 4;260(5113):1513-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Clinical Viro-Immunology, Central Laboratory of the Netherlands Red Cross Blood Transfusion Service, Amsterdam.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8502996" target="_blank"〉PubMed〈/a〉

    Global and local current sheet thickness estimates during the late growth phase (1992)
    In:  CASI
    Details
    Publication Date: 2004-12-03
    Description: The thinning and intensification of the cross tail current sheet during the substorm growth phase are analyzed during the CDAW 6 substorm (22 Mar. 1979) using two complementary methods. The magnetic field and current sheet development are determined using data from two spacecraft and a global magnetic field model with several free parameters. These results are compared with the local calculation of the current sheet location and structure previously done by McPherron et al. Both methods lead to the conclusion that an extremely thin current sheet existed prior to the substorm onset, and the thicknesses estimated by the two methods at substorm onset agree relatively well. The plasma data from the ISEE 1 spacecraft at 13 R(sub E) show an anisotropy in the low energy electrons during the growth phase which disappears just before the substorm onset. The global magnetic model results suggest that the field is sufficiently stretched to scatter such low energy electrons. The strong stretching may improve the conditions for the growth of the ion tearing instability in the near Earth tail at substorm onset.
