    Postdoctoral patterns, career advancement, and problems (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-09-08
    Description: Postdoctoral appointments can have different functions and meanings, depending on the field and whether the postdoc is a man or a woman. The Ph.D.'s-Ten Years Later study confirmed that in biochemistry, the postdoc, not the Ph.D., has become the general proving ground for excellence both in academia and industry. Because they spent a longer time in these "mandatory" postdocs, biochemists had the largest proportion of untenured faculty 10 to 13 years after the Ph. D. In mathematics, where substantially fewer postdoctoral positions are available, Ph.D.'s taking postdocs are more likely to obtain faculty positions, but this is true only for men. University administrators should be accountable for monitoring the total time spent in these positions and should provide administrative assistance for skills training, career growth, and the job search. In addition, creative solutions concerning the dual-career couple phenomenon are necessary.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nerad, M -- Cerny, J -- New York, N.Y. -- Science. 1999 Sep 3;285(5433):1533-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate Division, University of California, Berkeley, 424 Sproul Hall, Berkeley, CA 94720-5900, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10477510" target="_blank"〉PubMed〈/a〉

    Diminishing returns from mutation supply rate in asexual populations (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-01-15
    Description: Mutator genotypes with increased mutation rates may be especially important in microbial evolution if genetic adaptation is generally limited by the supply of mutations. In experimental populations of the bacterium Escherichia coli, the rate of evolutionary adaptation was proportional to the mutation supply rate only in particular circumstances of small or initially well-adapted populations. These experiments also demonstrate a "speed limit" on adaptive evolution in asexual populations, one that is independent of the mutation supply rate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arjan, J A -- Visser, M -- Zeyl, C W -- Gerrish, P J -- Blanchard, J L -- Lenski, R E -- New York, N.Y. -- Science. 1999 Jan 15;283(5400):404-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Microbial Ecology, Michigan State University, East Lansing, MI 48824, USA. arjan.devisser@algemeen.micr.wau.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9888858" target="_blank"〉PubMed〈/a〉

    Population biology, evolution, and infectious disease: convergence and synthesis (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-02-05
    Description: Traditionally, the interest of population and evolutionary biologists in infectious diseases has been almost exclusively in their role as agents of natural selection in higher organisms. Recently, this interest has expanded to include the genetic structure and evolution of microparasite populations, the mechanisms of pathogenesis and the immune response, and the population biology, ecology, and evolutionary consequences of medical and public health interventions. This article describes recent work in these areas, emphasizing the ways in which quantitative, population-biological approaches have been contributing to the understanding of infectious disease and the design and evaluation of interventions for their treatment and prevention.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levin, B R -- Lipsitch, M -- Bonhoeffer, S -- New York, N.Y. -- Science. 1999 Feb 5;283(5403):806-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Emory University, 1510 Clifton Road, Atlanta, GA 30322, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9933155" target="_blank"〉PubMed〈/a〉

    CD3- and CD28-dependent induction of PDE7 required for T cell activation (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-02-05
    Description: Costimulation of both the CD3 and CD28 receptors is essential for T cell activation. Induction of adenosine 3',5'-monophosphate (cAMP)-specific phosphodiesterase-7 (PDE7) was found to be a consequence of such costimulation. Increased PDE7 in T cells correlated with decreased cAMP, increased interleukin-2 expression, and increased proliferation. Selectively reducing PDE7 expression with a PDE7 antisense oligonucleotide inhibited T cell proliferation; inhibition was reversed by blocking the cAMP signaling pathways that operate through cAMP-dependent protein kinase (PKA). Thus, PDE7 induction and consequent suppression of PKA activity is required for T cell activation, and inhibition of PDE7 could be an approach to treating T cell-dependent disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, L -- Yee, C -- Beavo, J A -- DK21723/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1999 Feb 5;283(5403):848-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology and Molecular and Cellular Biology Program, Box 357280, University of Washington School of Medicine, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9933169" target="_blank"〉PubMed〈/a〉

    An activating immunoreceptor complex formed by NKG2D and DAP10 (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-07-31
    Description: Many immune receptors are composed of separate ligand-binding and signal-transducing subunits. In natural killer (NK) and T cells, DAP10 was identified as a cell surface adaptor protein in an activating receptor complex with NKG2D, a receptor for the stress-inducible and tumor-associated major histocompatibility complex molecule MICA. Within the DAP10 cytoplasmic domain, an Src homology 2 (SH2) domain-binding site was capable of recruiting the p85 subunit of the phosphatidylinositol 3-kinase (PI 3-kinase), providing for NKG2D-dependent signal transduction. Thus, NKG2D-DAP10 receptor complexes may activate NK and T cell responses against MICA-bearing tumors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, J -- Song, Y -- Bakker, A B -- Bauer, S -- Spies, T -- Lanier, L L -- Phillips, J H -- AI30581/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1999 Jul 30;285(5428):730-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉DNAX Research Institute, 901 California Avenue, Palo Alto, CA 94304, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10426994" target="_blank"〉PubMed〈/a〉

    Antiangiogenic activity of the cleaved conformation of the serpin antithrombin (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-09-18
    Description: Antithrombin, a member of the serpin family, functions as an inhibitor of thrombin and other enzymes. Cleavage of the carboxyl-terminal loop of antithrombin induces a conformational change in the molecule. Here it is shown that the cleaved conformation of antithrombin has potent antiangiogenic and antitumor activity in mouse models. The latent form of intact antithrombin, which is similar in conformation to the cleaved molecule, also inhibited angiogenesis and tumor growth. These data provide further evidence that the clotting and fibrinolytic pathways are directly involved in the regulation of angiogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Reilly, M S -- Pirie-Shepherd, S -- Lane, W S -- Folkman, J -- P01-CA45548/CA/NCI NIH HHS/ -- R01-CA64481/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1999 Sep 17;285(5435):1926-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Surgery, Children's Hospital, Departments of Surgery and Cellular Biology, Harvard Microchemistry Facility, 16 Divinity Avenue, Cambridge, MA 02138, USA. oreilly@hub.tch.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10489375" target="_blank"〉PubMed〈/a〉

    Efficient persistence of extrachromosomal KSHV DNA mediated by latency-associated nuclear antigen (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-04-24
    Description: Primary effusion lymphoma (PEL) cells harbor Kaposi's sarcoma-associated herpesvirus (KSHV) episomes and express a KSHV-encoded latency-associated nuclear antigen (LANA). In PEL cells, LANA and KSHV DNA colocalized in dots in interphase nuclei and along mitotic chromosomes. In the absence of KSHV DNA, LANA was diffusely distributed in the nucleus or on mitotic chromosomes. In lymphoblasts, LANA was necessary and sufficient for the persistence of episomes containing a specific KSHV DNA fragment. Furthermore, LANA colocalized with the artificial KSHV DNA episomes in nuclei and along mitotic chromosomes. These results support a model in which LANA tethers KSHV DNA to chromosomes during mitosis to enable the efficient segregation of KSHV episomes to progeny cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ballestas, M E -- Chatis, P A -- Kaye, K M -- CA67380-04/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1999 Apr 23;284(5414):641-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Channing Laboratory, Brigham and Women's Hospital, Harvard Medical School, 181 Longwood Avenue, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10213686" target="_blank"〉PubMed〈/a〉

    Pigment epithelium-derived factor: a potent inhibitor of angiogenesis (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-07-10
    Description: In the absence of disease, the vasculature of the mammalian eye is quiescent, in part because of the action of angiogenic inhibitors that prevent vessels from invading the cornea and vitreous. Here, an inhibitor responsible for the avascularity of these ocular compartments is identified as pigment epithelium-derived factor (PEDF), a protein previously shown to have neurotrophic activity. The amount of inhibitory PEDF produced by retinal cells was positively correlated with oxygen concentrations, suggesting that its loss plays a permissive role in ischemia-driven retinal neovascularization. These results suggest that PEDF may be of therapeutic use, especially in retinopathies where pathological neovascularization compromises vision and leads to blindness.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dawson, D W -- Volpert, O V -- Gillis, P -- Crawford, S E -- Xu, H -- Benedict, W -- Bouck, N P -- New York, N.Y. -- Science. 1999 Jul 9;285(5425):245-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology-Immunology, Department of Pathology, Robert H.

    Description: Biological weapons have recently attracted the attention and the resources of the nation. Discerning the nature of the threat of bioweapons as well as appropriate responses to them requires greater attention to the biological characteristics of these instruments of war and terror. The dominant paradigm of a weapon as a nuclear device that explodes or a chemical cloud that is set adrift leaves us ill-equipped conceptually and practically to assess and thus to prevent the potentially devastating effects of bioterrorism. Strengthening the public health and infectious disease infrastructure is an effective step toward averting the suffering that could be wrought by a terrorist's use of a biological agent.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Henderson, D A -- New York, N.Y. -- Science. 1999 Feb 26;283(5406):1279-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Johns Hopkins Center for Civilian Biodefense Studies, Johns Hopkins School of Public Health, Suite 850, Candler Building, 111 Market Place, Baltimore, MD 21202, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10037590" target="_blank"〉PubMed〈/a〉

    Complexity, pattern, and evolutionary trade-offs in animal aggregation (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-04-02
    Description: One of the most striking patterns in biology is the formation of animal aggregations. Classically, aggregation has been viewed as an evolutionarily advantageous state, in which members derive the benefits of protection, mate choice, and centralized information, balanced by the costs of limiting resources. Consisting of individual members, aggregations nevertheless function as an integrated whole, displaying a complex set of behaviors not possible at the level of the individual organism. Complexity theory indicates that large populations of units can self-organize into aggregations that generate pattern, store information, and engage in collective decision-making. This begs the question, are all emergent properties of animal aggregations functional or are some simply pattern? Solutions to this dilemma will necessitate a closer marriage of theoretical and modeling studies linked to empirical work addressing the choices, and trajectories, of individuals constrained by membership in the group.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parrish, J K -- Edelstein-Keshet, L -- New York, N.Y. -- Science. 1999 Apr 2;284(5411):99-101.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Zoology Department, University of Washington, Seattle, WA 98195, USA. jparrish@u.washington.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10102827" target="_blank"〉PubMed〈/a〉

    Description: Interactions between species are as evolutionarily malleable as the species themselves and have played a central role in the diversification and organization of life. This malleability creates complex geographic mosaics in interspecific interactions that can evolve rapidly over decades, blurring the distinction between evolutionary time and ecological time and making the study of coevolution crucial for human health and welfare.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thompson, J N -- New York, N.Y. -- Science. 1999 Jun 25;284(5423):2116-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Botany and Zoology, Washington State University, Pullman, WA 99164, USA. jnt@wsu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10381869" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-04-02
    Description: Calcium-calmodulin-dependent protein kinase II (CaMKII) is thought to increase synaptic strength by phosphorylating postsynaptic density (PSD) ion channels and signaling proteins. It is shown that N-methyl-D-aspartate (NMDA) receptor stimulation reversibly translocates green fluorescent protein-tagged CaMKII from an F-actin-bound to a PSD-bound state. The translocation time was controlled by the ratio of expressed beta-CaMKII to alpha-CaMKII isoforms. Although F-actin dissociation into the cytosol required autophosphorylation of or calcium-calmodulin binding to beta-CaMKII, PSD translocation required binding of calcium-calmodulin to either the alpha- or beta-CaMKII subunits. Autophosphorylation of CaMKII indirectly prolongs its PSD localization by increasing the calmodulin-binding affinity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shen, K -- Meyer, T -- GM-48113/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1999 Apr 2;284(5411):162-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology and Department of Pharmacology and Cancer Biology, Box 3709, Duke University Medical Center, Durham, NC 27710, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10102820" target="_blank"〉PubMed〈/a〉

    BRCA1 inhibition of estrogen receptor signaling in transfected cells (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-05-21
    Description: Mutations of the breast cancer susceptibility gene BRCA1 confer increased risk for breast, ovarian, and prostatic cancers, but it is not clear why the mutations are associated with these particular tumor types. In transient transfection assays, BRCA1 was found to inhibit signaling by the ligand-activated estrogen receptor (ER-alpha) through the estrogen-responsive enhancer element and to block the transcriptional activation function AF-2 of ER-alpha. These results raise the possibility that wild-type BRCA1 suppresses estrogen-dependent transcriptional pathways related to mammary epithelial cell proliferation and that loss of this ability contributes to tumorigenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fan, S -- Wang, J -- Yuan, R -- Ma, Y -- Meng, Q -- Erdos, M R -- Pestell, R G -- Yuan, F -- Auborn, K J -- Goldberg, I D -- Rosen, E M -- R01-CA75503/CA/NCI NIH HHS/ -- R01-ES09169/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1999 May 21;284(5418):1354-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Radiation Oncology, Long Island Jewish Medical Center, The Long Island Campus for the Albert Einstein College of Medicine, 270-05 76th Avenue, New Hyde Park, NY 11040, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10334989" target="_blank"〉PubMed〈/a〉

    Publication Date: 1999-06-26
    Description: The fossil record provides a powerful basis for analyzing the controlling factors and impact of biological evolution over a wide range of temporal and spatial scales and in the context of an evolving Earth. An increasingly interdisciplinary paleontology has begun to formulate the next generation of questions, drawing on a wealth of new data, and on methodological advances ranging from high-resolution geochronology to simulation of morphological evolution. Key issues related to evolutionary biology include the biotic and physical factors that govern biodiversity dynamics, the developmental and ecological basis for the nonrandom introduction of evolutionary innovations in time and space, rules of biotic response to environmental perturbations, and the dynamic feedbacks between life and the Earth's surface processes. The sensitivity of evolutionary processes to rates, magnitudes, and spatial scales of change in the physical and biotic environment will be important in all these areas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jablonski, D -- New York, N.Y. -- Science. 1999 Jun 25;284(5423):2114-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geophysical Sciences, University of Chicago 5734 South Ellis Avenue Chicago, IL 60637, USA. djablons@midway.uchicago.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10381868" target="_blank"〉PubMed〈/a〉

    Phylogenetic classification and the universal tree (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-06-26
    Description: From comparative analyses of the nucleotide sequences of genes encoding ribosomal RNAs and several proteins, molecular phylogeneticists have constructed a "universal tree of life," taking it as the basis for a "natural" hierarchical classification of all living things. Although confidence in some of the tree's early branches has recently been shaken, new approaches could still resolve many methodological uncertainties. More challenging is evidence that most archaeal and bacterial genomes (and the inferred ancestral eukaryotic nuclear genome) contain genes from multiple sources. If "chimerism" or "lateral gene transfer" cannot be dismissed as trivial in extent or limited to special categories of genes, then no hierarchical universal classification can be taken as natural. Molecular phylogeneticists will have failed to find the "true tree," not because their methods are inadequate or because they have chosen the wrong genes, but because the history of life cannot properly be represented as a tree. However, taxonomies based on molecular sequences will remain indispensable, and understanding of the evolutionary process will ultimately be enriched, not impoverished.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Doolittle, W F -- New York, N.Y. -- Science. 1999 Jun 25;284(5423):2124-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Canadian Institute for Advanced Research, Department of Biochemistry and Molecular Biology, Dalhousie University, Halifax, Nova Scotia B3H 4H7, Canada. ford@is.dal.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10381871" target="_blank"〉PubMed〈/a〉

    Signaling from Rho to the actin cytoskeleton through protein kinases ROCK and LIM-kinase (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-08-07
    Description: The actin cytoskeleton undergoes extensive remodeling during cell morphogenesis and motility. The small guanosine triphosphatase Rho regulates such remodeling, but the underlying mechanisms of this regulation remain unclear. Cofilin exhibits actin-depolymerizing activity that is inhibited as a result of its phosphorylation by LIM-kinase. Cofilin was phosphorylated in N1E-115 neuroblastoma cells during lysophosphatidic acid-induced, Rho-mediated neurite retraction. This phosphorylation was sensitive to Y-27632, a specific inhibitor of the Rho-associated kinase ROCK. ROCK, which is a downstream effector of Rho, did not phosphorylate cofilin directly but phosphorylated LIM-kinase, which in turn was activated to phosphorylate cofilin. Overexpression of LIM-kinase in HeLa cells induced the formation of actin stress fibers in a Y-27632-sensitive manner. These results indicate that phosphorylation of LIM-kinase by ROCK and consequently increased phosphorylation of cofilin by LIM-kinase contribute to Rho-induced reorganization of the actin cytoskeleton.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maekawa, M -- Ishizaki, T -- Boku, S -- Watanabe, N -- Fujita, A -- Iwamatsu, A -- Obinata, T -- Ohashi, K -- Mizuno, K -- Narumiya, S -- New York, N.Y. -- Science. 1999 Aug 6;285(5429):895-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Kyoto University Faculty of Medicine, Kyoto 606-8315, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10436159" target="_blank"〉PubMed〈/a〉

    Association of BRCA1 with the hRad50-hMre11-p95 complex and the DNA damage response (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-07-31
    Description: BRCA1 encodes a tumor suppressor that is mutated in familial breast and ovarian cancers. Here, it is shown that BRCA1 interacts in vitro and in vivo with hRad50, which forms a complex with hMre11 and p95/nibrin. Upon irradiation, BRCA1 was detected in discrete foci in the nucleus, which colocalize with hRad50. Formation of irradiation-induced foci positive for BRCA1, hRad50, hMre11, or p95 was dramatically reduced in HCC/1937 breast cancer cells carrying a homozygous mutation in BRCA1 but was restored by transfection of wild-type BRCA1. Ectopic expression of wild-type, but not mutated, BRCA1 in these cells rendered them less sensitive to the DNA damage agent, methyl methanesulfonate. These data suggest that BRCA1 is important for the cellular responses to DNA damage that are mediated by the hRad50-hMre11-p95 complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhong, Q -- Chen, C F -- Li, S -- Chen, Y -- Wang, C C -- Xiao, J -- Chen, P L -- Sharp, Z D -- Lee, W H -- CA 30195/CA/NCI NIH HHS/ -- CA 58183/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1999 Jul 30;285(5428):747-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Medicine, Institute of Biotechnology, University of Texas Health Science Center at San Antonio, 15355 Lambda Drive, San Antonio, TX 78245, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10426999" target="_blank"〉PubMed〈/a〉

    Identification of a nuclear receptor for bile acids (1999)

    Details
    Publication Date: 1999-05-21
    Description: Bile acids are essential for the solubilization and transport of dietary lipids and are the major products of cholesterol catabolism. Results presented here show that bile acids are physiological ligands for the farnesoid X receptor (FXR), an orphan nuclear receptor. When bound to bile acids, FXR repressed transcription of the gene encoding cholesterol 7alpha-hydroxylase, which is the rate-limiting enzyme in bile acid synthesis, and activated the gene encoding intestinal bile acid-binding protein, which is a candidate bile acid transporter. These results demonstrate a mechanism by which bile acids transcriptionally regulate their biosynthesis and enterohepatic transport.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Makishima, M -- Okamoto, A Y -- Repa, J J -- Tu, H -- Learned, R M -- Luk, A -- Hull, M V -- Lustig, K D -- Mangelsdorf, D J -- Shan, B -- New York, N.Y. -- Science. 1999 May 21;284(5418):1362-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Pharmacology, University of Texas Southwestern Medical Center, 5323 Harry Hines Boulevard, Dallas, TX 75235-9050, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10334992" target="_blank"〉PubMed〈/a〉
