果菊苷组细胞TGFβ 蛋白表达量较对照组降低;TGFβ 过表达组较对照组升高;TGFβ 过表达+ 松果菊苷组较
TGFβ 过表达组降低,较松果菊苷组升高(P 均<0. 05)。结论 松果菊苷可以通过阻断TGFβ 表达来抑制人脑胶
质瘤细胞的迁移和侵袭能力。

Methods Human glioma cells were cultured in vitro and were divided into the control , , , group echinacoside group TGFβ overexpression group and TGFβ overexpression + echinacoside group. Cells in the
continued to culture for 24 h. The cell scratch test was used to observe the cell migration ability of each group. Transwell
, assay was used to observe the cell invasion ability and the expression of TGFβ protein was detected by Western blotting. , Results The healing rate of the echinacoside group was lower than that of the control group the TGFβ overexpression , group was higher than the control group and TGFβ overexpression + echinacoside group was lower than the TGFβ over ( ) expression group and higher than the echinacoside group all P < 0. 05 . The number of transmembrane cells in the echina , , coside group was lower than that in the control group the TGFβ overexpression group was higher than the control group

摘要:目的 观察松果菊苷对人脑胶质瘤细胞迁移及侵袭的影响,并探讨其作用机制。方法 体外培养人脑
胶质瘤细胞,将细胞分为对照组、松果菊苷组、转化生长因子β(TGFβ)过表达组、TGFβ 过表达+ 松果菊苷组。使
用Lipofectamine3000 转染细胞,对照组、松果菊苷组转染空载质粒,TGFβ 过表达组、TGFβ 过表达+ 松果菊苷组转
染TGFβ 质粒。转染后24 h 向松果菊苷组、TGFβ 过表达+ 松果菊苷组中加入松果菊苷30 μmol/ L,继续培养24
h。采用细胞划痕实验观察细胞迁移能力,Transwell 实验观察细胞侵袭能力,Western blotting 法检测细胞TGFβ 蛋
白表达量。结果 松果菊苷组划痕愈合率较对照组降低,TGFβ 过表达组较对照组升高;TGFβ 过表达+ 松果菊
苷组较TGFβ 过表达组降低,较松果菊苷组升高(P 均< 0. 05)。松果菊苷组穿膜细胞数较对照组减少,TGFβ 过
表达组较对照组增加;TGFβ 过表达+ 松果菊苷组较TGFβ 过表达组减少,较松果菊苷组增加(P 均< 0. 05)。松

Effects of echinacoside on migration and invasion of human glioma cells
control group and the echinacoside group were transfected with empty plasmids. Cells in the TGFβ overexpression group
, and the TGFβ overexpression + echinacoside group were transfected with the TGFβ plasmid. At 24 h after transfection , we added 30 μmol / L echinacoside to the echinacoside group and TGFβ overexpression + echinacoside group and then
