ET-18-OCH3 induces translocation of Fas into GM1-containing lipid rafts.
Untreated Jurkat cells (Control) and Jurkat cells treated with 5 μg/mL ET-18-OCH3 for 3 hours were lysed in 1% Triton X-100 in TNEV buffer and subjected to discontinuous sucrose density gradient centrifugation. Individual fractions (20 μL) were subjected to SDS-PAGE and Western blotting. Location of GM1 and Fas was determined using CTx B subunit conjugated to horseradish peroxidase and anti-Fas polyclonal antibody, respectively, as described in “Materials and methods.” Representative blots of 3 separate experiments are shown.
