| Abstract: | AIM: To investigate the effects of axitinib on the biological behavior of adrenocortical carcinoma cell line SW-13. METHODS: CCK-8 assay was used to measured the viability of SW-13 cells treated with axitinib at different concentrations. The cell cycle distribution was analyzed by flow cytometry. The apoptotic rate was also analyzed by flow cytometry with Annexin V/PI double staining. Wound healing experiment and Transwell invasion assay were used to observe cell migration and invasion abilities,respectively. The protein levels of vascular endothelial growth factor receptor 2(VEGFR2), extracellular regulated protein kinases 1/2 (ERK1/2) and p-ERK1/2 were determined by Western blot. RESULTS: After treated with axitinib, the viability of SW-13 cells was significantly inhibited, the cell cycle was blocked in G2/M phase, and the apoptosis rate was increased. The migration and invasion abilities of SW-13 cells were markedly inhibited by axitinib (P<0.01). The protein levels of VEGFR2 and p-ERK1/2 in the SW-13 cells were significantly decreased with axitinib treatment (P<0.01). CONCLUSION: Axitinib inhibits the viability, blocks the cell cycle, promotes cell apoptosis, and inhibits the migration and invasion abilities of SW-13 cells. The mechanism may be related to inhibition of VEGFR2 expression and reduction of ERK1/2 phosphorylation. |
