1、蚌埠醫(yī)學院學報2014年4月第39卷第4期433[文章編號]1000-2200(2014)04-0433-05·基礎(chǔ)醫(yī)學·I3整合素反義寡核苷酸聯(lián)合順鉑治療人卵巢癌裸鼠移植瘤的研究馬玲,田敏[摘要]目的:探討以13整合素反義寡核苷酸(ASODN)治療人卵巢癌裸鼠皮下移植瘤的可行性。方法:常規(guī)體外培養(yǎng)SKOV3細胞,采用皮下注射法建立移植瘤裸鼠動物模型。32只荷瘤鼠隨機分為ASODN組(A組)、ASODN聯(lián)合順鉑(DDP)組(A+D組)、DDP組和0.9%氯化鈉注射液對照組(Ns組),每組8只,分組給藥。以脂質(zhì)體包裹的母整合素ASODN直接移植瘤內(nèi)注射,觀察腫
2、瘤生長情況,測瘤體積并計算抑瘤率。采用反轉(zhuǎn)錄一聚合酶鏈反應(yīng)(RT-PCR)和免疫組織化學方法分別檢測p整合素mRNA的表達。結(jié)果:A組腫瘤體積和抑瘤率分別為(316.10±21.77)mm和48.15%,與Ns組比較抑瘤率較高,腫瘤生長緩慢(P<0.01)。而A+D組腫瘤體積和抑瘤率分別為(178.70±40.67)mm和7O.37%,與DDP組、A組及NS組差異均有統(tǒng)計學意義(P<0.05~P<0.01)。RT-PCR和免疫組織化學檢測,A組和A+D組腫瘤組織中B整合素mRNA的表達均明顯下調(diào)(P<0.01)。結(jié)論:單用B。整合素ASDON或聯(lián)用DDP均可
3、有效抑制人卵巢癌裸鼠皮下移植瘤組織的生長,可能與其特異性下調(diào)p。整合素基因表達有關(guān)。特異性靶向13。整合素ASODN可用于卵巢癌的輔助治療。[關(guān)鍵詞]卵巢腫瘤;反義寡核苷酸;p整合素[中國圖書資料分類法分類號]R737.31[文獻標志碼]AExperimentalstudyofintegrinantisenseoligodeonucleotideincombinationwithcisplatinforhumanovariancarcinomaxenograftinnudemiceMALing,TIANMin。(J.DepartmentofTumorGyne
