摘要
目的:探讨五味子乙素(schisandra B,SchB)对膀胱癌细胞增殖、迁移和侵袭的影响及分子机制。方法:采用不同浓度的五味子乙素溶液(0、20、40、80μmol/L)处理膀胱癌细胞,CCK-8法检测五味子乙素对膀胱癌细胞增殖的影响;Transwell迁移实验和细胞划痕实验检测五味子乙素对膀胱癌细胞迁移的影响;Transwell侵袭实验检测五味子乙素对膀胱癌细胞侵袭能力的影响;Western blot检测细胞内β-catenin、c-myc蛋白表达水平的变化。结果:五味子乙素呈时间和剂量依赖性抑制T24和UM-UC-3细胞的增殖能力(P<0.05)。细胞划痕愈合率、迁移和侵袭细胞数随着五味子乙素浓度增加而降低(P<0.05)。五味子乙素能够下调膀胱癌细胞内β-catenin和c-myc蛋白的表达(P<0.05)。结论:五味子乙素可抑制人膀胱癌T24和UM-UC-3细胞的增殖、迁移和侵袭,抑制Wnt/β-catenin信号通路的激活可能是其发挥抑癌作用的主要机制。
Objective:To investigate the effects of Schisandra B on proliferation,migration,invasion of bladder cancer and to further investigate its molecular mechanism.Methods:Bladder cancer cells were subjected to different concentrations of Schisandra B solution(0,20,40,80μmol/L).CCK-8 assay was used to detect the effect of schisandra B on bladder cancer cell proliferation.Transwell migration assay and wound healing assay were used to detect the effect of Schisandra B on the migration of bladder cancer cells.Transwell invasion assay was used to detect the effect of schisandra B on invasion ability of bladder cancer cells.The expression levels of intracellularβ-catenin and c-myc protein were measured by western blot.Results:Schisandra B inhibited the proliferation of T24 and UM-UC-3 cells in a concentration and time dependent manner(P<0.05).The rate of wound healing and number of migration and invasion cells decreased with the increase of Schisandra B concentration(P<0.05).The expression ofβ-catenin and c-myc decreased after treatment with Schisandra B in bladder cancer cells(P<0.05).Conclusion:Schisandra B can inhibit the proliferation,migration and invasion of human bladder cancer T24 and UM-UC-3 cells,and the main mechanism for its inhibitory effect may be related to the inactivation of the Wnt/β-catenin signaling pathway.
