LETM1在食管鳞癌中表达的临床病理意义及其与肿瘤干细胞的关系研究
发布时间:2021-04-15 07:24
背景:亮氨酸拉链EF-hand结构域跨膜蛋白1(LETM1)是一种线粒体蛋白,与多种器官肿瘤的发生密切相关,它在肿瘤(如胃癌、肺癌、卵巢癌、肾癌、结直肠癌、肝癌等)中过度表达,提示它与人类多种恶性肿瘤的发生、发展密切相关。但目前关于LETM1在食管鳞癌中表达的研究还未见报道,而且LETM1与肿瘤干细胞的关系目前也还不清楚。目的:本文探讨了 LETM1在食管鳞癌中表达的临床病理意义及其在评估食管鳞癌患者预后的价值。另外,进一步深入研究LETM1与肿瘤干细胞的关系,为食管鳞癌的靶向治疗提供新靶点。方法:从组织学水平和细胞学水平上分别检测LETM1的表达情况。首先采用免疫组织化学法检测LETM1在166例食管鳞癌组织标本和16例癌旁正常食管粘膜上皮组织标本中的表达情况,从而进一步统计分析LETM1的表达与临床病理参数、肿瘤干细胞标志物、肿瘤微环境相关因子,以及细胞周期相关因子的关系;另外采用Kaplan-Meier生存分析证明LETM1对评估食管鳞癌患者预后的有效价值。其次,利用蛋白质印迹法及免疫荧光法检测在食管鳞癌细胞系(TE1、TE8、TE10、TE11、ECG10、HCE7)中LETM...
