Objective To examine whether casticin influences the apoptosis, migration, and invasion of human cervical cancer HeLa and SiHa cells. Methods HeLa and SiHa cells were treated with various concentration of casticin, cell viability was examined by MTT assay and the apoptosis induced by casticin was determined by flow cytometry. The scratch test, matrigel assay, and Transwell test were performed respectively to estimate the capabilities of migration, adhesion, and invasion of HeLa and SiHa cells. The protein expression of nm23-H1 and MTA1 in SiHa cells was analyzed by Western blotting. Results Casticin treatment significantly inhibited cell viability, increased apoptosis rate, decreased migration percentages and adhesion of HeLa and SiHa cells, and reduced invasion cells number. The protein expression of nm23-H1 was evidently enhanced, but that of MTA1 was significantly decreased. Conclusion Casticin markedly induces the apoptosis and suppresses the migration and invasion of HeLa and SiHa cells, suggesting its potential therapeutic effects on cervical cancer.
