摘要:

目的: 探讨姜黄素抑制SW480细胞的作用机制。方法: 应用内盐法(MTS)检测方法观察SW480细胞活性及姜黄素的干预影响;应用Western blot、实时定量PCR研究姜黄素对SW480细胞的信号干预机制,检测上皮细胞钙粘蛋白(E-cadherin)、波形蛋白(Vimentin)、β-链蛋白(β-catenin)、T细胞转录因子4(TCF4)基因等表达量。结果: SW480细胞增殖活性在姜黄素干预下被明显抑制,姜黄素对SW480细胞增殖IC50分别为(75.75±3.17) μmol/L(12 h)、(21.15±2.47) μmol/L(24 h)、(18.95±1.75) μmol/L(48 h)、(17.93±1.55) μmol/L(72 h);姜黄素干预下,SW480细胞内Ecadherin、Vimentin明显上调,而βcatenin、TCF4明显下调,且呈剂量依赖性。结论: 姜黄素能抑制SW480细胞活性,并通过Wnt/βcatenin信号通路发挥靶向抑制作用。

Abstract:

AIM: To study the effect of curcumin on human colon cancer cells SW480.  METHODS: Cell viability and the effects of curcumin on the activity of SW480 cells were detected by MTS method. Expressions of β-catenin and TCF4 were detected by Western blot. E-cadherin and Vimentin by real-time qPCR assay in human colon cancer cells SW480. RESULTS:Curcumin could significantly inhibit the proliferation of SW480 cells and the IC50 were (75.75±3.17) μmol/L(12 h), (21.15±2.47) μmol/L(24 h), (18.95±1.75) μmol/L(48 h), (17.93±1.55) μmol/L(72 h). Curcumin could up-regulate the expression of E-cadherin, and down-regulate the expression of Vimentin, β-catenin and TCF4 in SW480 cells. CONCLUSION: Curcumin can inhibit the the activity of SW480 cells through the Wnt/β-catenin signaling pathway.

Key words: curcumin, SW480 cells, β-catenin, TCF4, inhibition
