摘要: 目的: 探讨Twist1调控上皮-间质转化(EMT)促进舌鳞状细胞癌细胞顺铂耐药的机制。方法: 在CAL27/CDDP中转染Twist1 siRNA,免疫印迹及免疫荧光检测E-cadherin、Vimentin的表达;免疫印迹检测Twist1、Slug的表达;Transwell及划痕实验检测细胞的侵袭、迁移能力;MTT检测细胞对顺铂的半抑制率。采用SPSS17.0 软件包对结果进行单因素方差分析。结果: 转染Twist1 siRNA可逆转CAL27/CDDP的EMT表型, E-cadherin表达增强,Vimentin、Twist1及Slug表达降低,细胞的侵袭、迁移能力明显降低,IC50下降41.75%±5.10%(P<0.01)。结论: Twist1可通过调控上皮-间质转化而促进舌鳞癌细胞的顺铂耐药。

Abstract: PURPOSE: The aim of this study was to investigate the mechanism of Twist1 regulating epithelial-mesenchymal transition (EMT) and cisplatin-resistance in tongue squamous carcinoma cells. METHODS: TSCC CDDP resistant cell line CAL27/CDDP was transfected with Twist1 siRNA. Western blot and immunofluorescence staining were used to detect the expression of E-cadherin and Vimentin; Western blot was used to detect the expression of Twist1 and Slug; Transwell assay and scratch test were used to detect the invasion and migration capabilities; MTT was used to analyze the half maximal inhibitory concentration (IC50) values. One-way ANOVA was used to analyze the results with SPSS 17.0 software package. RESULTS: Twist1 siRNA transfection reversed EMT phenotype of CAL27/CDDP. The expression of E-cadherin was up-regulated and the expression of Vimentin, Twist1 and Slug was down-regulated. The motility was significantly decreased. The IC50 of CAL27/CDDP decreased by 41.75%±5.10%(P<0.01). CONCLUSIONS: Twist1 promotes EMT and CDDP drug-resistance in TSCC.
