摘要
Abstract
Objective To study the anti -proliferation and apoptosis induction effect of curcumin combined with LY294002 on human bladder cancer EJ cells.Methods The growth inhibition of curcumin and LY294002 alone or in combination on bladder cancer EJ cells by MTT assay.Effects of curcumin and LY294002 alone or in combination with phosphatidylinositol - 3 - kinases ( PI3 K) inhibitor LY294002 on apoptosis of EJ cells were detected by flow cytometry (FCM).Curcumin and LY294002 alone or in combination regulated caspase -3 and PARP protein expression in EJ cells by Western blotting analysis.Results The inhibition ratio of proliferation of EJ cells was increased significantly by the combination application of curcumin with LY294002 (P < 0.05 ).The apoptotic ratio of EJ cells was increased by curcumin in combination with LY294002.Conclusion The tumor - killing effect of curcumin on bladder cancer EJ cells could be increased significantly by the combination application of inhibiting phosphatidylinositol - 3 - kinases/protein kinases (PI3K/Akt) signal transduction and improving apoptosis may be involved in its inhibitory effects.关键词
