摘要
目的:研究舒林酸体外逆转卵巢癌细胞系CP70的顺铂耐药性,并探讨其与β-catenin表达的关系。方法:MTT法检测单独使用舒林酸或顺铂及两药联合使用时对CP70细胞的抑制作用,免疫细胞化学和Western blot方法检测细胞内β-catenin表达水平。结果:两药联合处理细胞后顺铂耐药逆转倍数为6.01,联合处理组的细胞中β-catenin表达明显降低。结论:舒林酸能部分逆转CP70细胞对顺铂的耐药性,且此作用可能与下调细胞的β-catenin表达有关。
Objective:To study the effect of sulindac in resensitizing cisplatin - resistant human ovarian cancer cells CP70, and to discuss the related mechanism. Methods: MTF assay was used to assess the inhibitory effects of sulindae, cisplatin alone or a combination of both on CP70 cells. Immunohistochemical analysis and Western blotting were employed to observe the expression of β - catenin in different groups. Results: The resensitizing fold of cisplatin combined with sulindac was 6.01. The expression of β - catenin had the most prominent decrease in CP70 cells in the combination group. Conclusion: Sulindac can partially resensitize cisplatin -resistant CP70 cells,which might be related to the down - regulation of β- catenin.
