研究背景:E盒锌指结合蛋白1 (Zinc finger E-box binding homeobox 1,ZEB1)在多种肿瘤中高表达,在某些肿瘤中可以作为预后判断的标志分子.然而,ZEB1在结肠癌中的临床意义尚不明确.目的:在结肠癌组织样本中检测ZEB1的表达水平,分析其与临床病理特征的相关性;在结肠癌HCT116细胞中下调ZEB1的表达,分析其对细胞生物学功能的影响.方法:用免疫组织化学的方法检测了108例结肠癌患者的石蜡包埋组织切片中ZEB1的表达,用生存分析及COX回归分析探讨其表达水平与结肠癌临床病理特征的相关性;用siRNA沉默ZEB1的表达,观察其表达下调对HCT116细胞增殖、凋亡、迁移和侵袭能力的影响.

背景:胃癌是全球排名第四的恶性肿瘤,免疫抑制微环境的建立与持续性存在是导致胃癌发生发展的重要因素,我们前期的研究发现胃癌中CD8+T细胞功能受到抑制并介导了胃癌的不断进展和预后不良,而作为另一重要的抗肿瘤免疫细胞即NK细胞在胃癌中的功能和调控并不清楚.目的:研究NK细胞在胃癌中的功能变化及其调控,进一步阐明胃癌免疫逃逸的机制.方法:流式细胞技术检测NK细胞在胃癌患者不同组织中的分布、表型及功能,流
