Abstract:
OBJECTIVE: To study the effect of melittin on apoptsis and necrosis of osteosarcoma cell line U2 OS in vitro. METHODS: Osteosarcoma cell line U2 OS was treated with melittin. The growth and proliferation was observed by MTT assay and cell counting, and the necrosis was estimated by Trypan blue staining. The cell apoptsis, Fas and Apo2. 7 expression were detected by cytometer. RESULTS: The data showed that melittin could inhibit the proliferation of U2 OS dose-dependently at 16 and 64 mg/L. Cell apoptsis was detected by cytometer, when the cells were treated by 16 mg/L and 32 mg/L of melittin respectively, and the percentages of Fas and Apo2. 7 positive cells were increased. CONCLUSION: Melittin inhibits the proliferation of osterosarcoma cell line through up-regulating Fas expression and inducing apoptsis.
