The Study of Anti-cancer Mechanism with Bee Venom and Melittin on Human Prostatic Cancer Cell

전립선 암세포에 대한 봉약침액(蜂藥浸液) 및 Melittin 약침액(藥浸液)의 항암(抗癌) 기전(機轉) 연구(硏究)

Objectives : The purpose of this study was to investigate the anti-caner effect of Bee Venom and Melittin on the prostatic cancer cell(PC-3). The goal of study is to ascertain whether Bee Venom and Melittin inhibits the cell growth and cell cycle of PC-3, or the expression of relative genes and whether the regression of PC-3 cell growth is due to cell death or the expression of gene related to apoptosis. Methods : After the treatment of Pc-3 cells with Bee Venom and Melittin, we performed Fluorescence microscope, MTT assay, Western blotting, Flow cytometry, PAGE electrophoresis and Surface plasmon resonance analysis to identify the cell viability, apoptosis and gene related to apoptosis. Results : 1. Compared with Control cell, the inhibition of cell growth reduced in proportion with the dose of Bee Venom or Melittin($0{\sim}10{\mu}g/ml$) in PC-3. 2. In PC-3, Cell viabilities of Bee Venom or Melittin treatment was decreased significantly. 3. The nucli of Control cells were stained round and homogenous in DAPI staining, but those of PC-3 were stained condense and splitted. 4. In PC-3, apoptosis of Bee Venom or Melittin treatment was increased significantly. 5. Bax, Caspase-3 and P ARP of Bee Venom or Melittin treatment was increased significantly and Bcl-2 of Bee Venom or Melittin treatment was decreased significantly. Caspase-9 of Bee venom treatment was increased significantly. Conclusion : These results indicate that Bee Venom and Melittin inhibits the growth of prostate cancer cells, has anti-cancer effects by inducing apoptosis. We wish that the anti-cancer effects of Bee Venom and Melittin are used to clinical caner treatment.
