1Smad4基因沉默促进PanIN裸鼠移植瘤增殖和微血管形成的研究显示文摘背景与目的:由已建立的小鼠基因打靶模型证实,K-ras突变启动了胰腺癌前病变—胰腺腺管内上皮瘤(pancreatic intraepithelial neoplasia,PanIN),p53或p16失活均可单独促进小鼠PanIN发展为浸润性胰腺癌。作为人胰腺癌中另一失活频率高发的抑癌基因Smad4,其失活对PanIN的转化作用及是否可单独促进PanIN发展为胰腺癌目前仍不清楚。基于此目的,在已成功分离建立K-ras突变启动的PanIN细胞株基础上,本研究拟进一步应用RNA干扰技术沉默PanIN细胞株中内源性Smad4表达,以探讨siRNA干扰Smad4基因对PanIN细胞恶性转化作用。方法:构建Smad4基因沉默慢病毒质粒,筛选Smad4沉默稳转细胞并命名为PanIN-S细胞;分别用PanIN和PanIN-S细胞并采用皮下接种的方法,构建获得PanIN及PanIN-S细胞组裸鼠移植瘤模型(每组5只),2周后测定各组肿瘤体积和质量;应用免疫组织化学SP法检测并比较各组增殖细胞核抗原(PCNA)和CD31的表达及其差异。结果:成功构建了Smad4基因siRNA体系;与未干扰PanIN细胞组相比,PanIN-S组裸鼠肿瘤体积和质量显著增加(P<0.05);组织病理学检查,符合胰腺癌(腺癌);免疫组织化学结果显示PCNA和CD31表达显著增高(P<0.05)。结论:Smad4基因沉默可促使在K-ras突变基础上的小鼠PanIN细胞的恶性转化;裸鼠移植瘤中Smad4失活可显著促进小鼠移植瘤增殖和肿瘤微血管形成,这些可能是其致瘤恶性转化的重要作用机制。齐晓光 慎睿哲 王立夫 曹海霞 朱黎明 董文杰 孙萍胡 章永平 张本炎 Tuveson DA 2009中国癌症杂志2009,19,7:5
