目的 研究Snail与卵巢癌侵袭转移间的关系,并探讨其分子机制.方法 分别构建正义全长Snail真核表达载体和小分子干扰RNA,分别转染卵巢癌细胞系A2780、C13.采用Western 印迹方法分析相关蛋白表达,Transwell试验检测细胞侵袭转移能力.结果 ①成功构建Snail正义全长真核表达载体,并合成Snail小分子RNA干扰片段;② 在转染PEGFPC1/Snail的卵巢癌细胞株A2780、C13*中E-cadherin表达明显下调,Snail和Vimentin则表达上调;而在转染Snail/SiRNA的卵巢癌细胞株A2780、C13*中E-cadherin表达明显上调,Snail和Vimentin则表达下调;③ Snail过表达可显著促进卵巢癌细胞株A2780、C13*的侵袭转移潜能;封闭Snail表达水平可一定水平抑制卵巢癌细胞株A2780、C13*的侵袭转移潜能.结论 Snail可通过促进卵巢癌上皮细胞间质化转变(epithelial-mesenchymal transition,EMT)而提高其侵袭转移能力;封闭Snail表达可一定程度逆转卵巢癌上皮细胞间质化转变(EMT)而抑制其侵袭转移能力.
目的 研究Snail與卵巢癌侵襲轉移間的關繫,併探討其分子機製.方法 分彆構建正義全長Snail真覈錶達載體和小分子榦擾RNA,分彆轉染卵巢癌細胞繫A2780、C13.採用Western 印跡方法分析相關蛋白錶達,Transwell試驗檢測細胞侵襲轉移能力.結果 ①成功構建Snail正義全長真覈錶達載體,併閤成Snail小分子RNA榦擾片段;② 在轉染PEGFPC1/Snail的卵巢癌細胞株A2780、C13*中E-cadherin錶達明顯下調,Snail和Vimentin則錶達上調;而在轉染Snail/SiRNA的卵巢癌細胞株A2780、C13*中E-cadherin錶達明顯上調,Snail和Vimentin則錶達下調;③ Snail過錶達可顯著促進卵巢癌細胞株A2780、C13*的侵襲轉移潛能;封閉Snail錶達水平可一定水平抑製卵巢癌細胞株A2780、C13*的侵襲轉移潛能.結論 Snail可通過促進卵巢癌上皮細胞間質化轉變(epithelial-mesenchymal transition,EMT)而提高其侵襲轉移能力;封閉Snail錶達可一定程度逆轉卵巢癌上皮細胞間質化轉變(EMT)而抑製其侵襲轉移能力.
