Figure 3. Anti-proliferative effects of BLU-285 and FLT3 inhibitors on growth of TF-1-KIT-D816V cells, and effects of FLT3 inhibitors versus BLU-285 on phosphorylation of KIT.
(A) Anti-proliferative effects of BLU-285 and FLT3 inhibitors (100 nM) on growth of TF-1 and TF-1-KIT-D816V cells following 3 days of treatment. (B) Proliferation studies: Growth curves showing drug treatment effects on TF-1 or TF-1-KIT-D816V cells following 3 days of treatment. (C,D) Immunoblots: Measurement of drug effects on phosphorylation of KIT in TF-1-KIT-D816V cells following two hour treatments with inhibitors at a concentration of 200 nM. Phospho-KIT (Y719) antibody was used for (C) and phospho-KIT (Y703) antibody was used for (D).
