目的 研究银杏叶提取物EGB761对VH-64尤文肉瘤细胞的促凋亡作用。方法 EGB761干预VH-64尤文肉瘤细胞后,CCK- 8 观察 50、100 和200 mg/L不同浓度EGB761作用下VH-64尤文肉瘤细胞的增殖状况,流式细胞仪分析用AnnexinV-FITC和PI双染检测不同浓度EGB761对VH-64尤文肉瘤细胞凋亡的影响。结果 EGB761可抑制VH-64尤文肉瘤细胞的增殖,呈浓度和时间依赖性反应;EGB761 100 mg/L、200 mg/L干预VH-64尤文肉瘤细胞后,流式细胞仪检测显示细胞凋亡率分别为6.85%±0.36%和14.36%±0.23%,明显高于对照组(P<0.01)。结论 EGB761可诱导VH-64尤文肉瘤细胞凋亡。
Abstract
Objective To explore the contribution of EGB761 to the proliferation and apoptosis of Ewing’s sarcoma VH-64 cell in vitro. Methods CCK-8 assay was used to measure 50,100 and 200 mg/L which its effects on the proliferation of Ewing’s sarcoma VH-64 cell cultured with different concentrations of allicin for 12 h, 24 h, 48 h, AnnexinV-FITC and PI assay by flow cytometer (FCM) were applied to detect the apoptosis induced by EGB761. The changes of cell cycle were detected by FCM. Results EGB761 suppressed the proliferation of Ewing’s sarcoma VH-64 cell in a concentration-and time-dependent manner EGB761 induced cellular apoptosis of the Ewing’s sarcoma VH-64 cell in a concentration-dependent manner. With EGB761 100, 200 mg/L intervention Ewing’s sarcoma VH-64 cell, flow cytometer (FCM) test showed that the cell apoptosis rate were 6.85%±0.36% and 14.36%±0.23%,which were significant higher than that of control group (P< 0.01). Conclusions EGB761 significantly suppresses the growth of Ewing’s sarcoma VH-64 cell, induces the apoptosis of Ewing’s sarcoma VH-64 cell. Therefore resveratrol may be considered as a possible treatment medicine for Ewing’s sarcoma.
