A, CB17 SCID/beige mice injected in the tibiae with PC3 cells were treated with G-TPP or vehicle (DMSO), and limbs of representative animals in each group (#) were analyzed by µCT. B, Percent change in bone volume (BV)/total volume (TV) ratio in individual animals (top) or groups (middle) treated with DMSO or G-TPP, as determined by µCT reconstruction of bone lesions. Bottom, percent BV of tibial tumor limb (TT) or contralateral tibia (CT). Mean±SEM of individual determinations. C, PC3 cells were treated with G-TPP or 17-AAG for the indicated time intervals, and analyzed by Western blotting.
