Abstract
目的探索稳定过表达CD99前后霍奇金淋巴瘤细胞株L428细胞中差异表达的蛋白,并分析验证差异蛋白的功能。方法采用荧光差异凝胶双向电泳和质谱分析技术检测L428细胞稳定过表达CD99前后蛋白表达的差异,采用GOfact开放软件对差异蛋白进行聚类分析,筛选在细胞转化过程中起重要作用的蛋白,并分析验证其功能。结果筛选鉴定得到38个差异蛋白,其中在稳定过表达CD99的霍奇金淋巴瘤细胞株L428(L428-CD99细胞)中与CD99表达呈正相关的蛋白21个,呈负相关的蛋白17个,所得的38个差异蛋白中有32个蛋白参与了细胞的生物过程,35个蛋白参与了细胞的组成和构建,28个参与了抗氧化、蛋白结合、催化活性、酶调节、信号转导、结构分子、翻译调节和离子转运等多个方面。结论筛选得到38个差异蛋白,其中关于细胞骨架、细胞分化、信号通路、调节基因表达等蛋白的改变与H/RS细胞和B淋巴瘤细胞转化相关。
