چکیده

background: the anti-cancer effects of honey bee venom (bv) and chrysin might open a new window for treatment of chemo-resistant cancers. this study was designed to evaluate cytotoxic and pro-apoptotic effects of bv and chrysin on a2780cp cistplatin- resistant human ovarian cancer cells. methods: as per the study objectives, a2780cp cells were categorized to 4 groups: 3 experiment groups (treated either with bv or chrysin or bv + chrysin) and 1 control group (untreated cells).  experiment group cells were cultured and treated by different concentrations of bv and chrysin for 24 hours. then, experiment and control cells were studied with mtt assay, annexin v-fitc, dapi and acridine orange / propidium iodide statining, flow cytometry, caspase-3 and -9 assay, measurement of intracellular level of reactive oxygen species (ros) and rt-pcr. results: mtt assay showed that 8 μg/ml bv, 40 µg/ml chrysin and 6 + 15 μg/ml bv + chrysin co-treatment induced 50% cell death on a2780cp cells compared with controls (p < 0.001). morphological observations by inverted and fluorescent microscopy revealed ros generation and apoptotic cell death under exposure to bv or chrysin or bv + chrysin co-treatment. caspase-3 and -9 assay demonstrated that bv and chrysin triggered apoptosis through intrinsic pathway and rt-pcr demonstrated down-regulation of bcl-2. conclusion: honey bee venom and chrysin are effective for destroying chemoresistant ovarian cancer cells through activation of intrinsic apoptosis, which propose them as potential candidates to be used in development of improved chemotherapeutic agents in the future.
