    Pretranslational suppression of an insulin-responsive glucose transporter in rats with diabetes mellitus (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-07-07
    Description: A prominent feature of diabetes mellitus is the inability of insulin to appropriately increase the transport of glucose into target tissues. The contributions of different glucose transport proteins to insulin resistance in rats with streptozotocin-induced diabetes was evaluated. A glucose transporter messenger RNA and its cognate protein that are exclusively expressed in muscle and adipose tissue were specifically depleted in diabetic animals, and these effects were reversed after insulin therapy; a different glucose transporter and its messenger RNA that exhibit a less restricted tissue distribution were not specifically modulated in this way. Depletion of the muscle- and adipose-specific glucose transporter species correlates with and may account for the major portion of cellular insulin resistance in diabetes in these animals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garvey, W T -- Huecksteadt, T P -- Birnbaum, M J -- DK 38765/DK/NIDDK NIH HHS/ -- DK 39519/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1989 Jul 7;245(4913):60-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Endocrinology and Metabolism, VA Medical Center, Indianapolis, IN.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2662408" target="_blank"〉PubMed〈/a〉

    Transformation of rat fibroblasts by FSV rapidly increases glucose transporter gene transcription (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-03-20
    Description: Elevation of glucose transport is an alteration common to most virally induced tumors. Rat fibroblasts transformed with wild-type or a temperature-sensitive Fujinami sarcoma virus (FSV) were studied in order to determine the mechanisms underlying the increased transport. Five- to tenfold increases in total cellular glucose transporter protein in response to transformation were accompanied by similar increases in transporter messenger RNA levels. This, in turn, was preceded by an absolute increase in the rate of glucose transporter gene transcription within 30 minutes after shift of the temperature-sensitive FSV-transformed cells to the permissive temperature. The transporter messenger RNA levels in transformed fibroblasts were higher than those found in proliferating cells maintained at the nonpermissive temperature. The activation of transporter gene transcription by transformation represents one of the earliest known effects of oncogenesis on the expression of a gene encoding a protein of well-defined function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Birnbaum, M J -- Haspel, H C -- Rosen, O M -- AM35430-01/AM/NIADDK NIH HHS/ -- DK 35158/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1987 Mar 20;235(4795):1495-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3029870" target="_blank"〉PubMed〈/a〉

    A potent nonpeptide cholecystokinin antagonist selective for peripheral tissues isolated from Aspergillus alliaceus (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-10-11
    Description: A new, competitive, nonpeptide cholecystokinin (CCK) antagonist, asperlicin, was isolated from the fungus Aspergillus alliaceus. The compound has 300 to 400 times the affinity for pancreatic, ileal, and gallbladder CCK receptors than proglumide, a standard agent of this class. Moreover, asperlicin is highly selective for peripheral CCK receptors relative to brain CCK and gastrin receptors. Since asperlicin also exhibits long-lasting CCK antagonist activity in vivo, it should provide a valuable tool for investigating the physiological and pharmacological actions of CCK.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, R S -- Lotti, V J -- Monaghan, R L -- Birnbaum, J -- Stapley, E O -- Goetz, M A -- Albers-Schonberg, G -- Patchett, A A -- Liesch, J M -- Hensens, O D -- New York, N.Y. -- Science. 1985 Oct 11;230(4722):177-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2994227" target="_blank"〉PubMed〈/a〉
