综述评论 世界临床药物 WORLD CLINICAL DRUGS Vol, 40 NO. 1 【临床研究】 微小RNA与胰腺癌化疗耐药的研究进展 赵贝,张晓丹,李光慧,黄仲义,赵永红,王斌 (上海市静安区中心医院,复旦大学附属华山医院静安分院药剂科,上海200040) 摘要:胰腺癌是一种消化道恶性肿瘤,其5年存活率低于6%。现有的药物治疗不能大幅度提高患者应答率。因此,深入了 解治疗失败背后的机制,克服化疗耐受是亟需解决的问题。微小RNA(mRNA)是一类内生的、保守的、长度约为22个核 苷酸的非編码RNA,具有翻译水平调控基因表达的功能。近年来,越来越多的研究表明mRNA的表达上调或下调可作用于 不同的靶点或通路进而影响胰腺癌的发生、发展、预后和对治疗药物的耐受。通过 mIRNA的再表达或者抑制其过表达可以 提高胰腺癌细胞对化疗药物的敏感,其模拟物或抑制剂均有望成为未来治疗胰腺癌的靶向药物。本文旨在对参与调控胰腺癌 化疗耐受的 miRNA进行总结,为临床治疗胰腺癌寻找新的靶向治疗方案 关键词:胰腺癌:化疔耐受;微小RNA;靶向治疗 中图分类号:R7359:R979.1文献标志码:A文章编号:16729188(2019)01-0062-06 DOl:10.13683/wph201901.012 dvances of miRNA and the chemo-resistance of pancreatic cancer ZHAO Bei, ZHANG Xiao-dan, LI Guang-hui, HUANG Zhong-yi, ZHAO Yong-hong, WANG Bin* Department of pharmacy Jing an District Center Hospital of shanghai, Huashan Hospital Jing 'an Branch Affiliateel to Fudan University, Shanghai 200040, China) Abstract: Pancreatic cancer is the malignant tumor of digestive tract, which has a 5-year survival rate of less than 6%.
