Distinct apoptosis mechanisms with cabozantinib removal and with high-dose cabozantinib treatment. (A) Immunoblotting for wild-type CD74-ROS1, F2004V-, or F2075C-mutated cells with or without treatment with 1 μM cabozantinib. Cell lysates were immunoblotted to detect the indicated proteins. (B) Mitochondrial depolarization assay by flow cytometry was performed for wild-type CD74-ROS1 cell (treated with 50 μM rotenone or 1 μM cabozantinib), F2004V- or F2075C-mutated cells (with or without 1 μM cabozantib). Rotenone, a mitochondrial electron transport system inhibitor, was used to treat wild-type CD74-ROS1 cells as a positive control. Each value is shown as mean ± SD of three independent experiments. Statistical significance was calculated by a t test; * indicates p < 0.05 and n.s., p ≥ 0.05. Uncropped blots are presented in Supplementary Fig. S11.
