  • Title: T3 stimulation of 2-deoxy-D-glucose uptake in cultured chick embryo carcass derived cells, requires neosynthesis of proteins.
    Author: Gordon A, Schwartz H, Gross J.
    Journal: Acta Endocrinol (Copenh); 1987 Jun; 115(2):259-64. PubMed ID: 3604556.
    Abstract:
    T3 stimulated, in a dose dependent manner, the uptake of 2-deoxy-D-glucose (2-DOG) into cultured chick embryo carcass derived cells. A significant increase in sugar uptake was seen already at a T3 concentration of 1 pmol/l. The stimulation of 2-DOG uptake increased with time during the 6 h of exposure to T3. The hormone also stimulated, within 45 min, the incorporation of [3H]leucine and [3H]uridine into the trichloroacetic acid precipitable material of these cells. Actinomycin-D (100 micrograms/l) and cycloheximide (1 mg/l) each were capable of blocking the stimulatory effect of 10(-8) mol/l T3 on sugar uptake and on uridine and leucine incorporation. Thus, T3 in these cultured chick embryo cells stimulated sugar transport through processes dependent on neosynthesis of proteins. In this respect the effect of T3 is different from that seen in cultured chick embryo cardiomyocytes.
