Fig. 6. Tf accumulates in a juxtanuclear cluster in cells treated with CI-976. Clone 9 cells were treated for 10 minutes with (A) DMSO as a solvent control, (B) CI-976 (20 µM), (C) DuP-128 (5 µM) or (D) PKF-058-035 (10 µM). TRITC-Tf was then added (in the continuous presence of compounds indicated above) for 45 minutes at 37°C.
