Keyword:  NFκB家族蛋白卵巢癌细胞系蛋白质提取Western印迹法MTT检测;
Abstract: 目的:研究NFκB家族蛋白在卵巢癌细胞的表达及与卵巢癌细胞化疗耐药性关系.方法:培养13株卵巢癌细胞系,对其进行胞质、胞核蛋白质提取,Western 印迹法观察NFκB家族蛋白及其抑制物的表达,并用MTT检测药敏、观察NFκB家族蛋白与卵巢癌细胞化疗耐药性关系.结果:①P65、P50及IKB在胞质内表达阳性率分别为76.9%、81.8%、84.6%,P65、P50同时在胞核内表达,P50尤为明显,阳性率分别为15.3%、45.5%.②OV-MZ-5和OV-MZ-2774两个卵巢癌细胞系P65表达阳性,MTT检测IC50表现明显高值,显示耐药.结论:P65、P50在卵巢癌细胞的发生、发展中发挥作用,P50更为明显;P65与卵巢癌细胞的耐药关系密切,可望成为判断预后的新的标志物.
