摘要: 目的 观察四溴苯三唑(TBB)对甲状腺滤泡状癌细胞株FTC133的CK2ɑ、β-CATENIN和SURVIVIN mRNA和蛋白表达的影响,探讨TBB抗甲状腺癌的作用机制。方法 体外培养FTC133细胞,分对照组(DMSO组)和TBB组(终浓度为12.5、25和50μmol/L),MTT法测定细胞增殖抑制率;划痕实验测定细胞迁移;RT-PCR和Western blot法分别检测FTC133细胞CK2ɑ、β-CATENIN和SURVIVINmRNA和蛋白表达。结果 与对照组比较,TBB呈剂量依赖性抑制FTC133细胞的增殖和迁移。各TBB处理组CK2ɑmRNA表达水平明显降低(P<0.01);TBB组随着浓度的逐渐加大,CK2ɑ、β-CATENIN和SURVIVIN蛋白表达下降(P<0.01)。结论TBB在一定浓度范围内抑制甲状腺滤泡状癌细胞株FTC133的增殖和迁移,其机制可能与TBB下调CK2ɑ表达进而抑制WNT/β-CATENIN信号通路有关。

Abstract: Objective To observe the effects of 4,5,6,7-tetrabromobenzotriazole(TBB) on the expressions ofCK2ɑ,β-CATENIN and SURVIVINin thyroid papillary carcinoma cell line FTC133and to explore the possible underlyingmechanism. Methods FTC133 cellswere cultured in vitro and divided into control group(DMSO), TBBgroups(12.5, 25, 50μmol/L)randomly. The proliferationrateand migration of FTC133 cells was detected byMTTand wound healing method. TheCK2ɑ, β-CATENIN and SURVIVIN mRNA and protein expression levelswere determined by RT–PCR and Western blot. Results Compared with control group, the proliferationrate and migration of FTC133 cells wereinhibited by TBBin a dose–dependentmanner(P<0.01).The expression levels of mRNA and protein ofCK2ɑ were significantly decreased in the presence of different TBB in FTC133 cells(P<0.01), the protein expression level of β-CATENIN and SURVIVIN were decreased, too(P<0.01).Conclusion TBB inhibits the proliferation and migration of thyroid papillary carcinoma cell line FTC133 via WNT/β-CATENIN signaling pathway.
