目的:通过 RNA 干扰技术研究巨噬细胞移动抑制因子(MIF)对宫颈癌 Caski 细胞上皮-间质转化(EMT)的影响作用。方法通过构建重组真核表达载体 pGenesil-1-MIF siRNA,转染宫颈癌 Caski 细胞(Caski-pGenesil-MIF siRNA 组),同时设空载体转染组(Caski-pGenesil-1组)和空白对照组(Caski 组),采用荧光定量聚合酶链反应(PCR)和蛋白质印迹法(Western blot)检测 Caski 细胞中 MIF mRNA 相对表达量的变化,并检测转染前后 Caski 细胞中 EMT 相关指标E-cadherin 和 Vimentin 的表达变化。结果 pGenesil-1-MIF siRNA 转染 Caski 细胞后 MIF mRNA 的表达量减少,低于对照组,差异有统计学意义(P<0.05);RNA 干扰抑制 MIF 基因表达后,与对照组相比,pGenesil-1-MIF siRNA 组 Caski 细胞上皮标记物 E-cadherin mRNA 及蛋白表达水平上调(P<0.05),间叶标记物 Vimentin mRNA 及蛋白表达水平显著下调(P<0.05)。结论抑制 MIF基因表达可抑制宫颈癌 Caski 细胞发生 EMT 的能力。

Objective To investigate the effect of RNA interference (RNAi) targeting macrophage migration inhibitory factor (MIF) on epithelial-mesenchymal transition (EMT) in human cervical carcinoma Caski cells. Methods Recombinant eukaryotic expression plasmid pGenesil-MIF siRNA was constructed and identified, then transfected into human cervical cancer cells Caski using a lipofectamine. Experimental cells were classified into 3 groups: Caski-pGenesil-MIF siRNA group, Caski-pGenesil-1 group and Caski group. Fluorescent quantitation polymerase chain reaction and Western blot were used to detect the the expression of MIF mRNA and the expression of EMT related markers such as E-cadherin and Vimentin in Caski cells was determined before and after transfection. Results The eukaryotic expression vector pGenesil-1-MIF siRNA significantly decreased the expression of mRNA of MIF in Caski cells (P<0.05). After RNA interference inhibited the expression of MIF gene in Caski cells, the expression of E-cadherin mRNA and protein in Caski-pGenesil-MIF siRNA group was significantly higher than those in control groups (P<0.05), while the expression of Vimentin in Caski-pGenesil-MIF siRNA group was significantly lower than those in control groups (P<0.05). Conclusion Inhibition of MIF gene expression in cervical cancer Caski cells can inhibit the ability of the occurrence of epithelial-mesenchymal transition.
