Research on Roles of Nucleophosmin in Human Osteosarcoma Cells

Abstract

Nucleophosmin作为重要的核仁磷酸化蛋白,在细胞的生命活动过程中发挥多种功能,并在多种肿瘤细胞中发生表达与细胞定位的变化。为探究Nucleophosmin在人成骨肉瘤细胞MG63中的功能作用与分子机制,本论文在成功制备Nucleophosmin兔多克隆抗体的基础上,通过构建正常定位以及胞质定位的Nucleophosmin表达载体,结合免疫共沉淀(Co-IP)、GST-pulldown、免疫荧光共定位、免疫亲和纯化和液相色谱-串联质谱联用技术(LC-MS/MS),进行Nucleophosmin相互作用蛋白质组学分析,构建其相互作用蛋白网络;并进一步通过MTT、Transwell、划痕实...Nucleophosmin as an nuclear phosphorylation protein, playing an important role in the process of cell life. In order to explore the function and mechanism of Nucleophosmin in human osteosarcoma cell line MG63, this paper based on the success of preparing nucleophosmin rabbit polyclonal antibody, via constructing flag tag of nucleolar localization vector (pBoBi-NPM) and cytoplasmic localization vec...学位:理学硕士院系专业:医学院_微生物学学号:2452013115344
