Fig. 2. Signal activity specifically impaired in RIE1-
5/1 cells by OXO treatment. (A,B) Subconfluent (70
80% confluent) cells in 60 mm culture dishes were treated with either DMSO or 10 µM OXO for 24 hours. Protein amounts in whole cell lysates were normalized before standard western blotting for the indicated molecules. Data shown are representative of three independent experiments.
