7、C 和蛋白质免疫印迹法(Western blot-ting)测定细胞内 CSNK11mNA 与蛋白的表达变化，以鉴定转染效果;细胞划痕实验和 Transwell 实验检测细胞的迁移与侵袭能力变化，细胞免疫荧光染色观察细胞内上皮间质转化标志物钙黏附蛋白 E(E-cadherin)和波形蛋白(Vimentin)的表达强度，血管生成实验检测肿瘤血管生成情况，Western blotting 检测细胞中血管内皮生长因子(vascular endothelial growth factor，VEGF)、基质金属蛋白酶(matrix metallopeptidase，MMP)2(MMP-2)及 MMP-9
8、 的蛋白表达变化。结果:ICC 组织 CSNK11 mNA 相对表达量显著高于癌旁组织，且ICC 组织 CSNK11 阳性率也显著高于癌旁组织(P 0 01);与对照组和 si-NC 组比较，si-CSNK11 组 HUC-CT-1 细胞中 CSNK11 mNA 相对表达量和蛋白相对表达量均下调，细胞划痕愈合率降低，细胞迁移与侵袭数目均减少，E-cadherin 荧光密度值下降而 Vimentin 荧光密度值升高，细胞管样形成数目减少，细胞内04VEGF、MMP-2 及 MMP-9 的蛋白相对表达量均显著下调，差异均具有统计学意义(P 0 05)。结论:CSNK11 在 ICC 组织内呈高表达
9、，靶向下调 ICC 细胞 CSNK11 表达后可抑制细胞迁移、侵袭及上皮间质转化过程，并减少血管生成，从而控制肿瘤进展。关键词胆管细胞性肝癌;酪蛋白激酶 11;转移;血管生成 中图分类号735 7 文献标志码A 文章编号1671-6264(2023)01-0040-09doi:10 3969/j issn 1671-6264 2023 01 006Expression of CSNK11 in cholangiocarcinoma and its relationshipwith tumor metastasis and angiogenesisTANG Jintian1，TANG unjua

11、e the expression of casein kinase 1 alpha1(CSNK11)in intrahepatic cholan-giocarcinoma(ICC)tissues and its effect on tumor cell metastasis and angiogenesis Methods:Fifty ICC tissuesamples and adjacent tissue samples from Affiliated Tumor Hospital of Xinjiang Medical University were collected，and the
12、expression level of CSNK11 was detected by real-time quantitative PC(qT-PC)and immunohisto-chemical staining The ICC cell line HUCCT-1 was cultured and randomly divided into control group，si-NC groupand si-CSNK11 group The short hairpin NA sequence targeting CSNK11 gene was transfected into HUCCT-1c
13、ells by liposome-mediated method，the expression changes of CSNK11 mNA and protein in cells were measuredby qT-PC and Western blotting to identify the transfection effect Cell scratch assay and Transwell assay wereused to detect changes in cell migration and invasion abilities，cell immunofluorescence
