ABSTRACT
OBJECTIVE:
The aim of this study was to investigate the anti-proliferative effect of the salinomycin in cell proliferation and apoptosis in primary cultured human uterine leiomyoma cells.METHODS:
Cell viability was measured by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. Caspase-3 activity assay and DNA fragmentation assay were performed to determine the effect of apoptosis. The expression of apoptosis regulatory-related proteins was evaluated by western blot.RESULTS:
The cell viability and proliferation of uterine leiomyoma cells were significantly reduced by salinomycin treatment in a dose-dependent manner. DNA fragmentation assay results showed apoptotic cell death after salinomycin incubation. Salinomycin activated caspase-3, -8, and -9, causing apoptosis in uterine leiomyoma cells. Down-regulation of Bcl-2, XIAP, and FLIP with a concomitant increase in Bax, Fas, and DR5 were observed.CONCLUSION:
These results provided the first evidence that salinomycin induce both intrinsic and extrinsic apoptosis. Therefore, salinomycin may be a promising chemopreventive and therapeutic agent against human uterine leiomyoma.
