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
14、 staining was used to observethe expression intensity of intracellular epithelial-mesenchymal transition markers E-cadherin and Vimentin,angio-genesis assays was used to detect tumor angiogenesis,the protein expression changes of vascular endothelial growthfactor(VEGF),matrix metallopeptidase(MMP)2(
15、MMP-2)and MMP-9 in cells were detected by Western blot-ting esults:The relative expression of CSNK11 mNA in ICC tissue was significantly higher than that in adja-cent tissue,and the positive rate of CSNK11 in ICC tissue was also significantly higher than that in adjacent tissue(P 0 01)Compared with
16、the control group and si-NC group,the relative expression of CSNK11 mNA andprotein in HUCCT-1 cells of si-CSNK11 group were down-regulated,the wound healing rate of cells decreased,the number of cell migration and invasion decreased,the fluorescence density value of cadherin decreased while thefluorescence density value of Vimentin increased,and the number of cell tube-like formation decreased,at the sametime,the relative proteins expressions of VEGF,MMP-2 and MMP-9 in cells were significantly d
