RT112 cells were exposed to PD173074 (PD) (500 nM) for 0–24 h, TKI-258 (TK) (500 nM) or SU5402 (SU) (5 mM) for 1 h. Cells were lysed, FGFR3 was immunoprecipitated (immunoprecipitated, IP) and blots (immunoblot, IB) were probed for phospho-tyrosine and reprobed for FGFR3 or probed for phospho-ERK and reprobed for total ERK.

Cells were exposed to PD173074 or TKI-258 (500 nM) for 24 h. Cell cycle profile was analysed using the Guava Easycyte Plus flow cytometry system.

In vitro assays on CUX1-FGFR1-expressing Ba/F3 cells. a. IL-3 deprivation of Ba/F3 cells transduced with CUX1-FGFR1 resulted in transformation to growth factor independent growth. The mean growth ± SEM of three separate measurements over four consecutive days is presented. b. The dose-response curves of CUX1-FGFR1-transduced Ba/F3 cells, treated with TKI258 and PKC412 for 48 hours in the absence or presence of IL-3 (2ng/ml) are presented. Points represent the average results of two experiments done in triplicate plotted with the curve-fitting GraphPad Prism 5 software; bars, SD. The calculated IC50 for each inhibitor is indicated. c. Western blot analyses of CUX1-FGFR1-transformed Ba/F3 cells after treatment with PKC412 and TKI258. Phosphorylation of CUX1-FGFR1 and its downstream effectors STAT5 and RPS6K decreased with increasing inhibitor concentrations. Expression of total CUX1-FGFR1, STAT5 and RPS6K remained unaffected. d. Effect of PKC412 and TKI258 on apoptosis of CUX1-FGFR1-expressing Ba/F3 cells after treatment for 48 hours. The percentage of apoptotic plus necrotic CUX1-FGFR1-transduced Ba/F3 cells is indicated.

Ba/F3 cell lines expressing the recombinant TEL/kinase domain fusion protein for FGFR1-4 .Cells were grown in RPMI 1640 containing 10% FBS and 500 ng/mL puromycin. The parental Ba/F3 cell line transduced with an empty vector was grown in 10 ng/mL IL-3 (R & D systems). Cell viability was assessed at 72 hours using the Cell Titer 96 Aqueous One Solution (Promega). Data were plotted as percent viability relative to vehicle-treated cells and are shown as mean (± SD) from 3 experiments.
