垂体肿瘤转化基因(PTTG)是一种癌基因,其表达水平与肿瘤的发生、转移密切相关。上皮向间充质转化(EMT)是肿瘤进展和转移的关键步骤。本实验以卵巢上皮性肿瘤细胞株(A2780)为研究对象,观察了转化生长因子-β、螺旋、蜗牛、鼻涕、波形蛋白、E-钙粘附素在Ad-PTTG基因感染细胞过程中的表达上调及E-钙粘附素的下调作用。反之,Ad-PTTG siRNA感染卵巢癌细胞后,PTTG的耗竭发生逆转现象,提示PTTG在卵巢癌细胞的EMT诱导中起重要作用。
Pituitary tumor-transforming gene (PTTG) is an oncogene with its expression levels correlating with tumor development and metastasis. Epithelial to mesenchymal transition (EMT) is a crucial step in tumor progression and metastasis. Using ovarian epithelial tumor cell line (A2780) for loss-of-function or gain-of-function of PTTG in our experiments, we observed up regulation of TGF-β, twist, snail, slug, vimentin and down regulation of E-cadherin on infection of cells with Ad-PTTG cDNA. In contrast reverse phenomena was observed on depletion of PTTG on infection of cells with Ad-PTTG siRNA, suggesting an important role of PTTG in induction of EMT in ovarian cancer cells.
