Fig. 2. Radicicol restores TM-2 expression. Whole cell extracts with equal amounts of total protein from cells treated as described in Fig. 1 were analyzed by Western blotting for TM expression (top panel) and tubulin expression (bottom panel). A, ras-transformed NIH3T3 cells. B, MEK-1-S218D,S222D-infected NIH3T3 cells. TM isoforms TM-1, TM-2, and TM-3 are indicated. Blots were stripped and reprobed for tubulin.
