[Effect of Met kinase inhibitor BMS-777607 on proliferation and apoptosis of tongue cell line CAL 27 squamous cell carcinoma].

PURPOSE: To investigate the effect of Met kinase inhibitor BMS-777607 on proliferation and apoptosis of tongue squamous cell carcinoma cell line CAL27. METHODS: The effect of BMS-777607 on proliferation of CAL27 was detected by MTT method, clone formation assay and EdU cell imaging. Morphological changes of apoptosis of CAL27 cells induced by BMS-777607 were observed by Heochst33342 staining. JC-1 staining was used to detect the changes of mitochondrial membrane potential of CAL27 cells treated with BMS-777607. Western blot was used to detect the effect of BMS-777607 on the expression of proliferation protein Akt, p-Akt and apoptosis-related proteins Bcl-2, Cleaved caspase-3, Bax and Parp in CAL27 cells. The data were analyzed using SPSS 22.0 software package. RESULTS: BMS-777607 inhibited proliferation and promoted apoptosis of CAL27 cells in a concentration-dependent manner（P＜0.05）. It also inhibited the expression of Bcl-2 and p-Akt and promoted the expression of Bax, Cleaved caspase-3 and Parp protein (P＜0.05). CONCLUSIONS: BMS-777607 can inhibit proliferation and promote apoptosis of CAL27 cells.
