Abstract:
Objective To evaluate the effect of tyrosine kinase inhibitor BGJ398 on the proliferation,apoptosis and migration of human hepatocellular cancer Huh-7 cells and explore the mechanism.Methods The effects of 10 tyrosine kinase inhibitors on the survival of Huh-7 cells were detected by MTT assay,and the sensitivity of Huh-7 cells to BGJ398 was analyzed by single-target kinetic equation and biphasic kinetic equation respectively.Huh-7 cells were added with 10,30 and 90 nmol/L BGJ398 respectively,and the control group(without drugs)was set.The effects of BGJ398 on the apoptosis and cell cycle of Huh-7 cells were detected by flow cytometry after culturing at 37℃for 24 h,the effect on the migration ability was detected by wound healing assay and the effect on the expression of multiple pathway-related proteins was detected by Western blot.Results All of 10 tyrosine kinase inhibitors inhibited the proliferation of Huh-7 cells,among which Huh-7 cells were most sensitive to BGJ398 and the IC_(50)was(0.020±0.013)μmol/L;The response of Huh-7 cells to BGJ398 was composed of two phases with F_1 accounted for 92.8%(K_(d1)was 36 nmol/L)and F_2 accounted for 7.2%(K_(d2)>1 000μmol/L).Compared with the control group,the apoptosis rate and the percentage of Huh-7 cells in G1 phase increased significantly in 30 and 90 nmol/L BGJ398 groups(t=-6.407～-4.459,each P<0.05),while the percentage of Huh-7 cells in S phase decreased significantly in 10,30 and 90 nmol/L BGJ398 groups(t=2.982,7.859 and 12.425,respectively,each P<0.05);After 24 and 48 h of scratching,the scratch area of 30 and 90 nmol/L BGJ398groups decreased significantly(t=5.376～18.197,each P<0.05);The expression levels of phosphorylated fibroblast growth factor receptor(FGFR)and phosphorylated extracellular signal-regulated kinase 1/2(Erk1/2)protein decreased significantly in 30 and 90 nmol/L BGJ398 groups(t=4.015～6.729,each P<0.01).Conclusion BGJ398 can inhibit the proliferation and migration of human hepatocellular cancer Huh-7 cells,induce apoptosis and cell cycle arrest,which might be achieved by inhibiting FGFR phosphorylation and MAPK signaling pathway.BGJ398 is expected to be a potential agent for the treatment of hepatocellular cancer.
