( n = 3) (C) Immunoblots showing the effect of the LT339 and LT339 W209A on KIT expression. The quantification of KIT level is shown below the immunoblots ( n = 9). (D) Top : immunoblot analysis of the effect LT339 and LT339 W209A on KIT protein stability in the presence of cycloheximide (CHX) up to 4 h. Bottom : quantification of KIT protein stability after normalization to 0 h time point ( n = 4). (E) Immunoblots showing KIT protein stability in KIT-HEK293 cells transfected with LT339, LT339 W209A or plasmid control (CTR) treated with KIT ligand (KITLG, 100 ng/mL) or solvent control (PBS) in the presence of CHX (100 μg/mL). (F) Quantification of KIT protein stability after normalization to 0 h time point ( n = 5). Solid lines represent PBS control (KITLG − ) and dotted lines represent KITLG treatment (KITLG + ). (A and B) Nuclei were stained by DAPI (blue). Scale bar: 10 μm. Numbers below the images refer to the proportion of cells with KIT paranuclear dot-like staining to the total number of cells analyzed. (C, D and F) Error bars represent mean ± SEM. * p < 0.05, *** p < 0.001, ns = not significant were calculated by one-way ANOVA with post-hoc Tukey’s test (C), two-way ANOVA (D) or two-way ANOVA with post-hoc Bonferroni’s test (F).

Article Snippet: For KITLG induced KIT degradation experiments, KIT-293 cells were transfected with LT339, LT339 W209A or CTR for 48 h, followed by addition of CHX (100 μg/mL) and KITLG (100 ng/mL; Proteintech Group, HZ-1024) or PBS.
