摘　　要：目的:探讨白屈菜红碱(CHE)对人卵巢癌SKOV3细胞迁移、侵袭和上皮-间质转化(EMT)的抑制作用,阐明其相关作用机制。方法:体外培养SKOV3细胞,分为对照组和2.5、5.0、10.0、20.0及40.0μmol·L^(-1)CHE组,采用噻唑蓝(MTT)法检测各组细胞增殖抑制率。体外培养SKOV3细胞,分为对照组、转移生长因子β1(TGF-β1)组、TGF-β1+5μmol·L^(-1)CHE组和TGF-β1+10μmol·L^(-1)CHE组,采用细胞划痕实验检测各组细胞迁移率,Transwell小室实验检测各组细胞中迁移细胞数和侵袭细胞数,Westren blotting法检测各组细胞中E-钙黏蛋白(E-cadherin)、N-钙黏蛋白(N-cadherin)和波形蛋白(Vimentin)蛋白表达水平,免疫荧光染色法检测各组细胞中E-cadherin和N-cadherin荧光强度。结果:MTT法,与对照组比较,5.0、10.0、20.0和40.0μmol·L^(-1)CHE组细胞增殖抑制率明显升高(P<0.05或P<0.01)。细胞划痕实验,与对照组比较,TGF-β1组细胞迁移率明显升高(P<0.01);与TGF-β1组比较,TGF-β1+5μmol·L^(-1)CHE组和TGF-β1+10μmol·L^(-1)CHE组细胞迁移率明显降低(P<0.01)。Transwell小室实验,与对照组比较,TGF-β1组细胞中迁移细胞数和侵袭细胞数明显增加(P<0.05);与TGF-β1组比较,TGF-β1+5μmol·L^(-1)CHE组和TGF-β1+10μmol·L^(-1)CHE组细胞中迁移细胞数和侵袭细胞数明显减少(P<0.01)。Westren blotting法,与对照组比较,TGF-β1组细胞中E-cadherin蛋白表达水平明显降低(P<0.01),N-cadherin和Vimentin蛋白表达水平明显升高(P<0.05或P<0.01);与TGF-β1组比较,TGF-β1+5μmol·L^(-1)CHE组和TGF-β1+10μmol·L^(-1)CHE组细胞中E-cadherin蛋白表达水平明显升高(P<0.01),N-cadherin和Vimentin蛋白表达水平明显降低(P<0.01)。免疫荧光染色,与对照组比较,TGF-β1组细胞中E-cadherin荧光强度明显降低,N-cadherin荧光强度明显升高;与TGF-β1组比较,TGF-β1+5μmol·L^(-1)CHE组和TGF-β1+10μmol·L^(-1)CHE组细胞中E-cadherin荧光强度明显升高,N-cadherin荧光强度明显降低。结Objective:To discuss the inhibitory effect of chelerythrine(CHE)on the migration,invasion,and epithelial-mesenchymal transition(EMT)of the human ovarian cancer SKOV3 cells,and to clarify the associated mechanism.Methods:The SKOV3 cells were cultured in vitro and divided into control group and 2.5,5.0,10.0,20.0,and 40.0μmol·L^(-1) CHE groups.Methylthiazolydiphenyl-tetrazolium(MTT)assay was used to detect the inhibitory rates of proliferation of the cells in various groups.The SKOV3 cells were cultured in vitro and divided into control group,transforming growth factor-β1(TGF-β1)group,TGF-β1+5μmol·L^(-1) CHE group,and TGF-β1+10μmol·L^(-1) CHE group.Cell scratch assay was used to detect the migration rates of the cells in various groups;Transwell chamber assay was used to detect the numbers of migration and invasion cells in various groups;Western blotting method was used to detect the expression levels of E-cadherin,N-cadherin,and Vimentin proteins in the cells in various groups;immunofluorescence staining method was used to detect the fluorescence intensities of E-cadherin and N-cadherin in the cells in various groups.Results:The MTT assay results showed that compared with control group,the inhibitory rates of proliferation of the cells in 5.0,10.0,20.0,and 40.0μmol·L^(-1) CHE groups were significantly increased(P<0.05 or P<0.01).The cell scratch assay results showed that compared with control group,the migration rate of the cells in TGF-β1 group was increased(P<0.01);compared with TGF-β1 group,the migration rates of the cells in TGF-β1+5μmol·L^(-1) CHE group and TGF-β1+10μmol·L^(-1) CHE group were significantly decreased(P<0.01).The Transwell chamber assay results showed that compared with control group,the numbers of migration and invasion cells in TGF-β1 group were significantly increased(P<0.05);compared with TGF-β1 group,the numbers of migration and invasion cells in TGF-β1+5μmol·L^(-1) CHE group and TGF-β1+10μmol·L^(-1) CHE group were significantly decreased(P<0.01).The Western blo
