    Regulated delivery of therapeutic proteins after in vivo somatic cell gene transfer (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1999
    Beschreibung: Stable delivery of a therapeutic protein under pharmacologic control was achieved through in vivo somatic gene transfer. This system was based on the expression of two chimeric, human-derived proteins that were reconstituted by rapamycin into a transcription factor complex. A mixture of two adeno-associated virus vectors, one expressing the transcription factor chimeras and one containing erythropoietin (Epo) under the control of a promoter responsive to the transcription factor, was injected into skeletal muscle of immune-competent mice. Administration of rapamycin resulted in 200-fold induction of plasma Epo. Stable engraftment of this humanized system in immune-competent mice was achieved for 6 months with similar results for at least 3 months in a rhesus monkey.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ye, X -- Rivera, V M -- Zoltick, P -- Cerasoli, F Jr -- Schnell, M A -- Gao, G -- Hughes, J V -- Gilman, M -- Wilson, J M -- P01 AR/NS43648-03/AR/NIAMS NIH HHS/ -- P30 DK47757-05/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1999 Jan 1;283(5398):88-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Human Gene Therapy, University of Pennsylvania, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9872748" target="_blank"〉PubMed〈/a〉

    Regulation of protein secretion through controlled aggregation in the endoplasmic reticulum (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2000-02-05
    Beschreibung: A system for direct pharmacologic control of protein secretion was developed to allow rapid and pulsatile delivery of therapeutic proteins. A protein was engineered so that it accumulated as aggregates in the endoplasmic reticulum. Secretion was then stimulated by a synthetic small-molecule drug that induces protein disaggregation. Rapid and transient secretion of growth hormone and insulin was achieved in vitro and in vivo. A regulated pulse of insulin secretion resulted in a transient correction of serum glucose concentrations in a mouse model of hyperglycemia. This approach may make gene therapy a viable method for delivery of polypeptides that require rapid and regulated delivery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rivera, V M -- Wang, X -- Wardwell, S -- Courage, N L -- Volchuk, A -- Keenan, T -- Holt, D A -- Gilman, M -- Orci, L -- Cerasoli, F Jr -- Rothman, J E -- Clackson, T -- New York, N.Y. -- Science. 2000 Feb 4;287(5454):826-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉ARIAD Gene Therapeutics, 26 Landsdowne Street, Cambridge, MA 02139, USA. vrivera@ariad.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10657290" target="_blank"〉PubMed〈/a〉

    Distinct protein targets for signals acting at the c-fos serum response element (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1991-01-11
    Beschreibung: The c-fos serum response element (SRE) is a primary nuclear target for intracellular signal transduction pathways triggered by growth factors. It is the target for both protein kinase C (PKC)-dependent and -independent signals. Function of the SRE requires binding of a cellular protein, termed serum response factor (SRF). A second protein, p62TCF, recognizes the SRE-SRF complex to form a ternary complex. A mutated SRE that bound SRF but failed to form the ternary complex selectively lost response to PKC activators, but retained response to PKC-independent signals. Thus, two different signaling pathways act through discrete nuclear targets at the SRE. At least one of these pathways functions by recruitment of a pathway-specific accessory factor (p62TCF). These results offer a molecular mechanism to account for the biological specificity of signals that appear to act through common DNA sequence elements.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Graham, R -- Gilman, M -- AI27270/AI/NIAID NIH HHS/ -- CA45642/CA/NCI NIH HHS/ -- CA46370/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 Jan 11;251(4990):189-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cold Spring Harbor Laboratory, NY 11724.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1898992" target="_blank"〉PubMed〈/a〉
