摘要:

目的 研究多纳非尼抑制人胆管癌TFK-1细胞增殖、迁移和侵袭及促进凋亡的机制。方法 将人胆管癌TFK-1细胞分为对照组(加入等量的二甲基亚砜处理),2、5、10 μmol/L多纳非尼组。CCK-8法检测细胞增殖抑制率;平板克隆实验检测细胞增殖情况;流式细胞术检测细胞凋亡;Transwell实验检测细胞迁移和侵袭能力;蛋白质免疫印迹法检测通路蛋白Wnt、β-catenin、细胞周期蛋白-D1(Cyclin D1)、抗凋亡蛋白Bcl-2、促凋亡蛋白Bax的表达;免疫荧光实验检测β-catenin进入细胞核的变化。结果 随着多纳非尼浓度增加,TFK-1细胞增殖抑制率、凋亡率升高,平板克隆形成数、细胞迁移和侵袭数量逐渐减少,Wnt、β-catenin、Cyclin D1、Bcl-2表达均逐渐下降,Bax表达逐渐增高(P<0.05);免疫荧光显示,与对照组比较,2 μmol/L多纳非尼组能够抑制β-catenin进入细胞核(P<0.05)。结论 多纳非尼可以抑制人胆管癌TFK-1细胞增殖、迁移和侵袭,其机制可能与抑制Wnt/β-catenin通路活化及促进细胞凋亡相关。

Abstract:

Objective To study the mechanism of donafenib inhibiting the proliferation, migration and invasion of human cholangiocarcinoma TFK-1 cells and promoting apoptosis. Methods Human cholangiocarcinoma TFK-1 cells were divided into the control group (treated with the same amount of dimethyl sulfoxide) and the 2, 5 and 10 μmol/L donafenib groups. CCK-8 assay was used to detect the inhibition rate of cell proliferation. Cell proliferation was detected by plate cloning assay. Cell apoptosis was detected by flow cytometry. Transwell assay was used to detect cell migration and invasion. Western blot assay was used to detect the expression of pathway proteins Wnt, β-catenin, Cyclin D1, anti-apoptotic protein Bcl-2 and pro-apoptotic protein Bax. Immunofluorescence assay was used to detect changes of β-catenin into the nucleus. Results With the increase of donafenib concentration, the proliferation inhibition rate and apoptosis rate of TFK-1 cells increased, the number of plate clone formation, cell migration and invasion decreased gradually, the expression levels of Wnt, β-catenin, Cyclin D1 and Bcl-2 decreased gradually, and the expression of Bax increased gradually (P<0.05). Immunofluorescence results showed that 2 μmol/L donafenib could inhibit β-catenin from entering the nucleus compared with the control group (P<0.05). Conclusion Donafenib can inhibit the proliferation, migration and invasion of human cholangiocarcinoma TFK-1 cells, and the mechanism may be related to the inhibition of Wnt/β-catenin pathway activation and the promotion of apoptosis.
