Preliminary exploration for the mechanism of LLGL2 regulated by SOX2 in esophageal squamous cell carcinoma

Abstract

目的 探索SOX2敲低后,关键基因LLGL2在食管鳞癌发生及恶性进程中的作用机制。为食管鳞癌诊断和靶向治疗候选方案的建立奠定基础。 方法 1.应用实时荧光定量PCR和Westernblot分别从mRNA和蛋白水平观察SOX2敲低后,LLGL2的改变情况。 2.采用免疫荧光技术检测食管鳞癌和正常组织临床标本各15例,观察LLGL2的表达情况。 3.利用实时定量PCR技术,检测miR-142-3p在SOX2敲低后的表达情况以验证前期miRNA芯片结果。 4.构建含靶基因LLGL2mRNA3’UTR的荧光素酶报告基因质粒,并应用双荧光素酶报告实验验证miR-142-3p对靶基因LLGL2...Objective: To explore the roles of LLGL2 in the pathogenesis and progression of esophageal squamous cell carcinoma(ESCC) after knockdown of SOX2. To lay a foundation for the establishment of candidate schemes for the diagnosis and treatment of ESCC. Methods: 1. The changes of LLGL2 in mRNA and protein levels after SOX2 knockdown were observed by real-time PCR and Western blot. 2. The expres...学位:医学硕士院系专业:医学院_临床检验诊断学学号:2452014115352
