To explore the effect of histone deacetylase inhibitor, trichostatin A (TSA) on the growth of biliary tract cancer cell lines (gallbladder carcinoma cell line and cholangiocarcinoma cell line) in vivo and in vitro, and to investigate the perspective of histone deacetylase inhibitor in its clinical application.
The survival rates of gallbladder carcinoma cell line (Mz-ChA-l cell line) and cholangiocarcinoma cell lines (QBC939, KMBC and OZ cell lines) treated with various doses of TSA were detected by methylthiazoy tetrazolium (MTT) assay. A nude mouse model of transplanted gallbladder carcinoma (Mz-ChA-l cell line) was successfully established, and changes in the growth of transplanted tumor after treated with TSA were measured.
TSA could inhibit the proliferation of gallbladder carcinoma cell line (Mz-ChA-l cell line) and cholangiocarcinoma cell lines (QBC939, KMBC and OZ cell lines) in a dose-dependent manner. After the nude mouse model of transplanted gallbladder carcinoma (Mz-ChA-l cell line) was successfully established, the growth of cancer was inhibited in the model after treated with TSA.
TSA can inhibit the growth of cholangiocarcinoma and gallbladder carcinoma cell lines in vitro and in vivo.
探讨组蛋白去乙酰化酶抑制剂曲古抑菌素A(TSA)对胆道癌细胞系(胆囊癌细胞系和胆管癌细胞系)体内外生长的影响,并研究组蛋白去乙酰化酶抑制剂在其临床应用中的前景。
采用甲基噻唑基四氮唑(MTT)法检测不同剂量TSA处理的胆囊癌细胞系(Mz-ChA-1细胞系)和胆管癌细胞系(QBC939、KMBC和OZ细胞系)的存活率。成功建立了移植胆囊癌(Mz-ChA-1细胞系)裸鼠模型,并检测TSA处理后移植瘤生长的变化。
TSA能以剂量依赖的方式抑制胆囊癌细胞系(Mz-ChA-1细胞系)和胆管癌细胞系(QBC939、KMBC和OZ细胞系)的增殖。成功建立移植胆囊癌(Mz-ChA-1细胞系)裸鼠模型后,TSA处理组模型中的肿瘤生长受到抑制。
TSA能在体内外抑制胆管癌和胆囊癌细胞系的生长。
