    Central hypotensive effects of the alpha2a-adrenergic receptor subtype (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-08-09
    Description: alpha2-Adrenergic receptors (alpha2ARs) present in the brainstem decrease blood pressure and are targets for clinically effective antihypertensive drugs. The existence of three alpha2AR subtypes, the lack of subtype-specific ligands, and the cross-reactivity of alpha2AR agonists with imidazoline receptors has precluded an understanding of the role of individual alpha2AR subtypes in the hypotensive response. Gene targeting was used to introduce a point mutation into the alpha2aAR subtype in the mouse genome. The hypotensive response to alpha2AR agonists was lost in the mutant mice, demonstrating that the alpha2aAR subtype plays a principal role in this response.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacMillan, L B -- Hein, L -- Smith, M S -- Piascik, M T -- Limbird, L E -- HL38120/HL/NHLBI NIH HHS/ -- HL43671/HL/NHLBI NIH HHS/ -- HL48638/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1996 Aug 9;273(5276):801-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Vanderbilt University, Nashville, TN 37232, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8670421" target="_blank"〉PubMed〈/a〉

    Antibacterial agents that inhibit lipid A biosynthesis (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-11-08
    Description: Lipid A constitutes the outer monolayer of the outer membrane of Gram-negative bacteria and is essential for bacterial growth. Synthetic antibacterials were identified that inhibit the second enzyme (a unique deacetylase) of lipid A biosynthesis. The inhibitors are chiral hydroxamic acids bearing certain hydrophobic aromatic moieties. They may bind to a metal in the active site of the deacetylase. The most potent analog (with an inhibition constant of about 50 nM) displayed a minimal inhibitory concentration of about 1 microgram per milliliter against Escherichia coli, caused three logs of bacterial killing in 4 hours, and cured mice infected with a lethal intraperitoneal dose of E. coli.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Onishi, H R -- Pelak, B A -- Gerckens, L S -- Silver, L L -- Kahan, F M -- Chen, M H -- Patchett, A A -- Galloway, S M -- Hyland, S A -- Anderson, M S -- Raetz, C R -- New York, N.Y. -- Science. 1996 Nov 8;274(5289):980-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, Merck Research Laboratories, Rahway, NJ 07065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8875939" target="_blank"〉PubMed〈/a〉

    Small peptides as potent mimetics of the protein hormone erythropoietin (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-07-26
    Description: Random phage display peptide libraries and affinity selective methods were used to isolate small peptides that bind to and activate the receptor for the cytokine erythropoietin (EPO). In a panel of in vitro biological assays, the peptides act as full agonists and they can also stimulate erythropoiesis in mice. These agonists are represented by a 14- amino acid disulfide-bonded, cyclic peptide with the minimum consensus sequence YXCXXGPXTWXCXP, where X represents positions allowing occupation by several amino acids. The amino acid sequences of these peptides are not found in the primary sequence of EPO. The signaling pathways activated by these peptides appear to be identical to those induced by the natural ligand. This discovery may form the basis for the design of small molecule mimetics of EPO.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wrighton, N C -- Farrell, F X -- Chang, R -- Kashyap, A K -- Barbone, F P -- Mulcahy, L S -- Johnson, D L -- Barrett, R W -- Jolliffe, L K -- Dower, W J -- New York, N.Y. -- Science. 1996 Jul 26;273(5274):458-64.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Affymax Research Institute, 4001 Miranda Avenue, Palo Alto, CA 94304, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8662529" target="_blank"〉PubMed〈/a〉

    DPC4, a candidate tumor suppressor gene at human chromosome 18q21.1 (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-01-19
    Description: About 90 percent of human pancreatic carcinomas show allelic loss at chromosome 18q. To identify candidate tumor suppressor genes on 18q, a panel of pancreatic carcinomas were analyzed for convergent sites of homozygous deletion. Twenty-five of 84 tumors had homozygous deletions at 18q21.1, a site that excludes DCC (a candidate suppressor gene for colorectal cancer) and includes DPC4, a gene similar in sequence to a Drosophila melanogaster gene (Mad) implicated in a transforming growth factor-beta (TGF-beta)-like signaling pathway. Potentially inactivating mutations in DPC4 were identified in six of 27 pancreatic carcinomas that did not have homozygous deletions at 18q21.1. These results identify DPC4 as a candidate tumor suppressor gene whose inactivation may play a role in pancreatic and possibly other human cancers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hahn, S A -- Schutte, M -- Hoque, A T -- Moskaluk, C A -- da Costa, L T -- Rozenblum, E -- Weinstein, C L -- Fischer, A -- Yeo, C J -- Hruban, R H -- Kern, S E -- CA62924/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1996 Jan 19;271(5247):350-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8553070" target="_blank"〉PubMed〈/a〉

    Hyperresponsive B cells in CD22-deficient mice (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-11-01
    Description: CD22 is a surface glycoprotein of B lymphocytes that is rapidly phosphorylated on cytoplasmic tyrosines after antigen receptor cross-linking. Splenic B cells from mice with a disrupted CD22 gene were found to be hyperresponsive to receptor signaling: Heightened calcium fluxes and cell proliferation were obtained at lower ligand concentrations. The mice gave an augmented immune response, had an expanded peritoneal B-1 cell population, and contained increased serum titers of autoantibody. Thus, CD22 is a negative regulator of antigen receptor signaling whose onset of expression at the mature B cell stage may serve to raise the antigen concentration threshold required for B cell triggering.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Keefe, T L -- Williams, G T -- Davies, S L -- Neuberger, M S -- New York, N.Y. -- Science. 1996 Nov 1;274(5288):798-801.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Laboratory of Molecular Biology, Hills Road, Cambridge CB2 2QH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8864124" target="_blank"〉PubMed〈/a〉

    An alphabeta T cell receptor structure at 2.5 A and its orientation in the TCR-MHC complex (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-10-11
    Description: The central event in the cellular immune response to invading microorganisms is the specific recognition of foreign peptides bound to major histocompatibility complex (MHC) molecules by the alphabeta T cell receptor (TCR). The x-ray structure of the complete extracellular fragment of a glycosylated alphabeta TCR was determined at 2.5 angstroms, and its orientation bound to a class I MHC-peptide (pMHC) complex was elucidated from crystals of the TCR-pMHC complex. The TCR resembles an antibody in the variable Valpha and Vbeta domains but deviates in the constant Calpha domain and in the interdomain pairing of Calpha with Cbeta. Four of seven possible asparagine-linked glycosylation sites have ordered carbohydrate moieties, one of which lies in the Calpha-Cbeta interface. The TCR combining site is relatively flat except for a deep hydrophobic cavity between the hypervariable CDR3s (complementarity-determining regions) of the alpha and beta chains. The 2C TCR covers the class I MHC H-2Kb binding groove so that the Valpha CDRs 1 and 2 are positioned over the amino-terminal region of the bound dEV8 peptide, the Vbeta chain CDRs 1 and 2 are over the carboxyl-terminal region of the peptide, and the Valpha and Vbeta CDR3s straddle the peptide between the helices around the central position of the peptide.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garcia, K C -- Degano, M -- Stanfield, R L -- Brunmark, A -- Jackson, M R -- Peterson, P A -- Teyton, L -- Wilson, I A -- R01 CA58896/CA/NCI NIH HHS/ -- T32-A107244/PHS HHS/ -- New York, N.Y. -- Science. 1996 Oct 11;274(5285):209-19.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology and the Skaggs Institute of Chemical Biology, Scripps Research Institute, 10550 N.

    Phenotypes of mouse diabetes and rat fatty due to mutations in the OB (leptin) receptor (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-02-16
    Description: Mice harboring mutations in the obese (ob) and diabetes (db) genes display similar phenotypes, and it has been proposed that these genes encode the ligand and receptor, respectively, for a physiologic pathway that regulates body weight. The cloning of ob, and the demonstration that it encodes a secreted protein (leptin) that binds specifically to a receptor (OB-R) in the brain, have validated critical aspects of this hypothesis. Here it is shown by genetic mapping and genomic analysis that mouse db, rat fatty (a homolog of db), and the gene encoding the OB-R are the same gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chua, S C Jr -- Chung, W K -- Wu-Peng, X S -- Zhang, Y -- Liu, S M -- Tartaglia, L -- Leibel, R L -- DK26687/DK/NIDDK NIH HHS/ -- DK47473/DK/NIDDK NIH HHS/ -- HD28047/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1996 Feb 16;271(5251):994-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Human Behavior and Metabolism, Rockefeller University, New York 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8584938" target="_blank"〉PubMed〈/a〉

    The (BETA) Pictoris Phenomenon Among Herbig Ae/Be Stars (1996)
    In:  Other Sources
    Details
    Publication Date: 2011-08-23
    Description: We present a survey of high dispersion UV and optical spectra of Herbig Ae/Be (HAeBe) and related stars. We find accreting, circumstellar gas over the velocity range +100 to +400 km/s, and absorption profiles similar to those seen toward Beta Pic, in 36% of the 33 HAeBe stars with IUE data as well as in 3 non-emission B stars. We also find evidence of accretion in 7 HAeBe stars with optical data only. Line profile variability appears ubiquitous. As a group, the stars with accreting gas signatures have higher v sin i than the stars with outflowing material, and tend to exhibit large amplitude (greater than or equal to 1(sup m)) optical light variations. All of the program stars with polarimetric variations that are anti-correlated with the optical light, previously interpreted as the signature of a dust disk viewed close to equator-on, also show spectral signatures of accreting gas. These data imply that accretion activity in HAeBe stars is preferentially observed when the line of sight transits the circumstellar dust disk. Our data imply that the spectroscopic signatures of accreting circumstellar material seen in Beta Pic are not unique to that object, but instead are consistent with interpretation of Beta Pic as a comparatively young A star with its associated circumstellar disk.
