2、黏附、遷移和侵襲的抑制作用;細(xì)胞組化法檢測(cè)順鉑作用SKOV3細(xì)胞24h后細(xì)胞表面CD44v6的表達(dá)情況。結(jié)果:(1)順鉑對(duì)SKOV3細(xì)胞增殖的抑制作用呈濃度和時(shí)間依賴性,24、48h的IC分別為24.065±1.031、5.0834-0.128g/ml;(2)在第50rain時(shí)點(diǎn),25g/ml順鉑組與對(duì)照組對(duì)SKOV3細(xì)胞黏附力的抑制作用差異最顯著(P<0.05)。第2h時(shí)點(diǎn),12.5、25g/ml順鉑組對(duì)SKOV3細(xì)胞遷移的抑制作用顯著高于對(duì)照組(P<0.05)。第lOh15min時(shí)點(diǎn),25g/ml順鉑組對(duì)SKOV3細(xì)胞侵襲的抑制作用顯著高于對(duì)
3、照組(P<0.05)。(3)與對(duì)照組比較,25m1順鉑組細(xì)胞表面表達(dá)CD44v6明顯減少(P<0.05),而5g/ml順鉑組減少不明顯。結(jié)論:順鉑抑制SKOV3細(xì)胞轉(zhuǎn)移特性首先表現(xiàn)為抑制細(xì)胞的黏附和遷移,這與順鉑減少細(xì)胞表面CD44v6蛋白的表達(dá)密切相關(guān)。CD44v6將成為上皮性卵巢癌治療的新靶點(diǎn)?!娟P(guān)鍵詞】順鉑;SKOV3細(xì)胞;黏附;轉(zhuǎn)移;CD44v6分子中圖分類號(hào):R737.33文獻(xiàn)標(biāo)志碼:A文章編號(hào):1004—7379(2013)07—0538—04RealtimeanalysisofthecharacteristicofSKOV3cell
