The effect of the lysosomal sequestration of IM on Bcr-Abl signaling in SUN-stimulated cancer cells. SUN-stimulated cells were incubated with various TKIs concentration in the absence or presence BafA1. After 6 h, cell extracts were analyzed for the CrkL phosphorylation (Tyr207) and Bcr-Abl phosphorylation (Bcr (Tyr177)) using western blot analysis. (a) Cells incubated wit IM ± BafA1 (typical analysis). (b) Quantitative analysis of western blots using densitometry. (c) Cells incubated wit NIL ± BafA1 (typical analysis). (d) Quantitative analysis of western blots using densitometry. (e) Cells incubated wit DAS ± BafA1 (typical analysis). (f) Quantitative analysis of western blots using densitometry. Columns represent the means and standard deviations of four independent experiments.
