ABSTRACT
OBJECTIVE@#To investigate the effect of osthole on epidermal growth factor receptor tyrosine kinase (EGFR-TPK), matrix-metalloproteinase-2 (MMP-2), aminopeptidase N (APN) in bladder cancer cell and the underlying mechanism.
@*METHODS@#The T24 cell lines were cultured. The inhibitory effects of osthole on EGFR-TPK, APN and MMP-2 were evaluated by spectrophotometric and MTT assay. The caspase-3 activity and the expression COX-2 and VEGF in T24 were examined. The activity of NF-κB was determined by electrophoretic mobility shift assay.
@*RESULTS@#The half inhibition concentrations (IC50) of osthole on EGFR-TPK, APN and MMP-2 were (45.33±3.98), (28.21±3.23) and (8.11±0.54) µmol/L, respectively. The growth inhibitory rates for T24 cells were increased in a dose-dependent manner (P<0.05). The caspase-3 activities were significantly increased in T24 cells in the osthole group compared with control group, while the expression of angiogenesis related-protein COX-2, VEGF, and NF-κB in T24 cells were decreased.
@*CONCLUSION@#Through the inhibitory effect on EGFR-TPK, APN and MMP-2, osthole can decrease COX-2, VEGF and NF-κB expression while increase the activity of caspase-3, eventually blocking the growth and invasion of bladder cancer cell.
