1、2013年12月中成藥December2013第35卷第l2期ChineseTraditionalPatentMedicineV01.35No.12莪術(shù)油誘導(dǎo)卵巢癌順鉑耐藥細(xì)胞凋亡及對STAT信號傳導(dǎo)通路的影響李榮霞,劉首娟,孔德勝,李敏,李艷芳,史淑紅,(河北醫(yī)科大學(xué)第二醫(yī)院,河北石家莊050000)摘要:目的探討莪術(shù)油對人卵巢癌順鉑化療耐藥細(xì)胞SKOV3/DDP生長抑制作用及其對STAT信號傳導(dǎo)通路的影響。方法在培養(yǎng)SKOV3/DDP細(xì)胞株中加入不同質(zhì)量濃度的莪術(shù)油進(jìn)行刺激,利用光學(xué)顯微鏡觀察細(xì)胞形態(tài)學(xué)變化,MTT;免疫組化及半定量
2、逆轉(zhuǎn)錄·聚合酶鏈反應(yīng)(RT—PCR)技術(shù)檢測STAT3、Survivin、Caspase一3的表達(dá)情況。結(jié)果顯微鏡下可見不同質(zhì)量濃度莪術(shù)油作用后細(xì)胞數(shù)量,形態(tài)學(xué)有明顯改變;莪術(shù)油對SKOV3/DDP細(xì)胞增殖有抑制作用,呈明顯的時間一劑量關(guān)系(P<0.05);莪術(shù)油及其聯(lián)合順鉑作用后,STAT3、Survivin表達(dá)下調(diào),Caspase一3表達(dá)上調(diào)。結(jié)論莪術(shù)油抑制人卵巢癌耐藥細(xì)胞株增殖并誘導(dǎo)其凋亡,其機(jī)制可能與下調(diào)STAT3,Survivin,上調(diào)Caspase一3表達(dá)有關(guān)。關(guān)鍵詞:莪術(shù)油;卵巢癌;順鉑耐藥細(xì)胞;信號傳導(dǎo)子與轉(zhuǎn)錄激活子3;
