MEN1基因在胃癌中的作用与机制研究
发布时间:2021-07-21 14:50
第一部分MEN1与胃癌的相关性分析目的:检测MEN1在正常胃粘膜上皮细胞、胃癌细胞株、胃癌组织及癌旁正常组织中的表达,分析MEN1表达与胃癌的相关性。方法:1.收集胃癌临床标本及相应患者的临床资料,提取总RNA与总蛋白,同时制作组织蜡块。RTQ-PCR技术检测胃癌组织与癌旁正常组织中MNE1 mRNA的表达水平,应用Western blot与免疫组织化学(immunohistochemistry,IHC)技术检测组织中MEN1编码蛋白(Menin)的表达水平。比较MEN1在胃癌组织与癌旁正常组织中的表达水平,并进一步分析MEN1表达与胃癌临床病理特征的关系。2.收集永生化胃粘膜细胞GES1 及胃癌细胞株 AGS、MGC803、SGC7901、BGC823、HGC27,提取总RNA及总蛋白。RTQ-PCR与Western blot分别检测细胞中MEN1 mRNA与蛋白的表达,并分析MEN1的表达水平与胃癌的相关性。结果:1.免疫组化结果:MEN1在组织细胞中的表达有分布差异,MEN1在癌旁组织中主要是在核内分布(P<0.0001),而癌组织中主要在胞质分布(P<0.0001)...
