英文摘要研究背景及目的: 基于早期肝癌患者缺乏特异症状和体征,而中晚期肝癌患者治疗效率又比较低并且预后较差,探讨肝癌的早期诊断与其发生机制具有重要意义。miRNA是一类由内源基因编码的长度约为22个核苷酸的非编码单链RNA分子,它们在动植物中参与转录后基因表达调控,其形成过程从长链pri-miRNAs到pre-miRNAs,最后形成成熟miRNAs,可直接结合到mRNA的3’UTR,从而抑制mRNA的翻译,导致mRNA的降解,进而影响蛋白质的表达,改变生物过程。SNP是指基因组内单个核苷酸改变时发生DNA序列的多态性变化,SNP决定着群体和个体基因序列的细微差别,是人类基因组最常见的一种变异类型。本...; Background and Objective: To investigate the early diagnosis of liver cancer and its pathogenesis is important, because the early symptoms of liver cancer lack of specific symptoms, and treatment efficiency in patients with advanced hepatocellular carcinoma is low and the prognosis is not very well. miRNA is a class of endogenous gene encoding a length of about 22 nucleotides of noncoding single...; 学位:医学硕士; 院系专业:医学院_内科学; 学号:24520131153468
