오령지(五靈脂)가 유방암세포의 사멸에 미치는 영향

【Objectives: This study was designed to investigate the effects of Trogopterorum Faeces on the apoptostic cell death in breast cancer cells. Methods: In the experiment, the effects of Trogopterorum Faeces on proliferation rates and type of cell death were investigated using MCF-7 cells in vitro. The effects on expression levels of caspase 3 and caspase 9 were also investigated. Results: The effects on expression levels of caspase 3 and caspase 9 were also investigated. In the present results, treatment with Trogopterorum Faeces decreased proliferation rates in a dose dependent manner. $ID_{50}$ (50 % inhibitory dosage) was $177.2{\mu}g/ml$ . In addition, treatment with Trogopterorum Faeces increased percentage of apoptotic cells. Finally the expression level of caspase 3 and caspase 9 were elevated by treatment with Trogopterorum Faeces respectively. Conclusions: This study suggests that Trogopterorum Faeces can trigger caspase dependent apoptosis in MCF-7 cells.】
