Abstract

INTRODUCTION: This study aims to exhibit the growth inhibitory effect of quercetin on the human ovarian epithelial carcinoma cells (OVCAR-3) and scrutinize the effect of hyperthermia.METHODS: OVCAR-3 cells were exposed to different concentrations of quercetin and apoptotic changes were recorded with confocal microscopy and transmission electron microscopy. Also Annexin-V and reactive oxygen species (ROS) measurement were analyzed. Cytotoxicity was tested on quercetin exposed OVCAR-3 cells with hyperthermia.RESULTS: Quercetin has good anticancerous activities in vitro by inhibiting the proliferation of OVCAR-3 cells. The recorded IC50 value of quercetin was 122 μM for 48 hours. Hyperthermia didnot influence significantly on the growth inhibition of OVCAR-3 cells applied with quercetin.DISCUSSION and CONCLUSION: Our results demonstrated that quercetin could induce apoptosis in a time and concentration-dependent manner in OVCAR-3 cells.
