狗舌草提取物对多发性骨髓瘤U266细胞周期及凋亡标志物AnnexinV／PI的作用

An study of Tephroseris Kirilowii Turez. Houlub extract on cell cycle and apoptosis marker AnnexinV/PI of U266

目的 研究狗舌草提取物对U266细胞周期及凋亡标志物AnnexinV/PI的作用.方法 U266细胞株与狗舌草提取物共同培养,用流式细胞仪测定细胞周期及凋亡标志物AnnexinV/PI.结果 狗舌草总提取物影响266细胞周期,G0/G1期细胞减少,S期、G2/M期细胞增加,凋亡细胞增加,用AnnexinV/PI染色流式细胞仪检测,均显示细胞凋亡与狗舌草提取物有剂量依赖关系.结论 狗舌草提取物对U266细胞有诱导细胞凋亡作用.

Objective To study Tephroseris Kirilowii Turez.Houlub extract on cell cycle and apoptosis marker AnnexinV/PI of U266 in vitro..Methods U266 cells were cultured together with Tephroseris Kirilowii Turez.Houlub extract.Cell cycle and apoptosis marker AnnexinV/PI were detected by flow cytometry（FCM）.Results After exposure of U266 cells to Tephroseris Kirilowii Turez.Houlub extract.the cell cycle distribution was changed.There Was a decrease of cells in the G0/G1 phase with an increase of cells in the S phase and G2/M phase and apoptosis.FCM with staining of Annexix V FITC/PI showed a dependence of apoptotic cells with the dosage of Tephroseris Kirilowii Turez.Houlub extract.Conclusion Tephroseris Kirilowii Turez extract has strong cell apoptosis effect on U266 cells.
