宫颈癌组织中Twist、Snail、YB-1基因表达对细胞侵袭、上皮间质转化的影响

摘要

Objective: To study the effect of Twist, Snail and YB-1 gene expression in cervical cancer tissue on cell invasion and epithelial-mesenchymal transition.Methods: Cervical cancer tissue samples and tissue samples adjacent to carcinoma were collected from 138 patients with radical operation for cervical cancer, fluorescence quantitative PCR method was used to detect the mRNA expression of Twist, Snail and YB-1 genes, cell invasion-related genes and epithelial-mesenchymal transition marker genes, the Pearson test was used to analyze the correlation of Twist, Snail and YB-1 gene mRNA expression in cervical cancer tissue with cell invasion and epithelial-mesenchymal transition.Results: Twist, Snail and YB-1 gene mRNA expression in cervical cancer tissue were higher than those in tissue adjacent to carcinoma, the invasion genes STAT3, YAP1, TUG1, FoxM1 and Rab11 mRNA expression were higher than those in tissue adjacent to carcinoma, and the epithelial-mesenchymal transition markers E-cadherin and β-catenin gene mRNA expression were lower than those in tissue adjacent to carcinoma while vimentin gene mRNA expression was higher than that in tissue adjacent to carcinoma (P<0.05).Pearson test showed that Twist, Snail and YB-1 gene mRNA expression in cervical cancer tissue were directly correlated with cell invasion and epithelial-mesenchymal transition.Conclusion: Twist, Snail and YB-1 genes are highly expressed in cervical cancer tissue, and their abnormal expression directly leads to the increased tumor cell invasion activity and the aggravated epithelial-mesenchymal transition.%目的:探讨宫颈癌组织中Twist、Snail、YB-1基因表达对细胞侵袭、上皮间质转化的影响.方法:取138例宫颈癌根治术患者的宫颈癌组织标本、癌旁组织标本,采用荧光定量PCR法检测其中Twist、Snail、YB-1基因,细胞侵袭相关基因,上皮间质转化标志物基因的mRNA表达量,采用Pearson检验分析宫颈癌组织Twist、Snail、YB-1基因的mRNA表达与细胞侵袭、上皮间质转化的相关关系.结果:宫颈癌组织中Twist、Snail、YB-1基因的mRNA表达量高于癌旁组织,侵袭基因STAT3、YAP1、TUG1、FoxM1、Rab11的mRNA表达量高于癌旁组织,上皮间质转化标志物E-cadherin、β-catenin基因的mRNA表达量低于癌旁组织,vimentin基因的mRNA表达量高于癌旁组织(P<0.05).Pearson检验发现,宫颈癌组织中Twist、Snail、YB-1基因的mRNA表达量与细胞侵袭、上皮间质转化直接相关.结论:宫颈癌组织中存在Twist、Snail、YB-1基因高表达,且其表达异常直接导致肿瘤细胞的侵袭活性增加、上皮间质转化加剧.
