Figure Lengend Snippet: A, ATB-BMPA photolabeling . Indinavir (Ind), atazanavir (Atz), ritonavir (Rit), and tipranavir (Tip) (50 µM final concentrations) were added to 200 µg of LDM for 10 min at room temperature. ATB-BMPA (50 µM final concentration) was then added for 10 min at room temperature prior to UV irradiation. Biotinylated proteins were isolated as described in “ ” and then analyzed by immunoblot analysis using GLUT4 and GLUT1 antibodies. The effect of 20 µM cytochalasin B (CB) and no UV irradiation are shown for comparison. B, Quantification of ATB-BMPA results GLUT4 and GLUT1 protein were quantified using an Odyssey Infrared Imaging System. Data, normalized to vehicle treated controls, are shown as the mean ± S.E., n = 3; (*), p<0.05 vs. vehicle as determined by the Student's t test; (+), p<0.05 for ATB-BMPA/GLUT4 vs. ATB-BMPA/GLUT1 binding. C. Glucose Uptakes. Indinavir (Ind), atazanavir (Atz), ritonavir (Rit), and tipranavir (Tip) (50 µM) were added 5–6 min prior to glucose uptake in insulin-stimulated (1 µM insulin for 20 min) primary rat adipocytes and basal 3T3-L1 fibroblasts. [ 3 H]2-Deoxyglucose uptake was measured at 37°C for 1 min in primary rat adipocytes (open bar) and for 6 min in basal 3T3-L1 fibroblasts (filled bar). Data shown as mean uptakes ± S.E. relative to control, n = 4; (*), p<0.05 vs. vehicle; (+), p<0.05 primary adipocytes vs. basal 3T3-L1 fibroblasts.

Figure Lengend Snippet: The indicated concentrations of indinavir (Ind) were added to 50 µg of LDM for 10 min at room temperature. ATB-BMPA (50, 100, 200, 300 µM final concentration) was then added for an additional 10 min. Samples were UV irradiated and processed as described in “ ”. The data are expressed as Scatchard plots. Bound and Free represent the ATB-BMPA bound to GLUT4 and ATB-BMPA free in solution, respectively.
