维吾尔族妇女宫颈癌患者血清蛋白质组的二维液相色谱分析

摘要

目的:利用蛋白质二维液相色谱方法建立维吾尔族妇女宫颈癌患者血清蛋白质组特异的蛋白质差异表达谱.方法:收集与制备维吾尔族妇女宫颈癌患者血清样品,采用蛋白质二维液相色谱系统(ProteomeLabTMPF-2D)对血清样品进行分离与数据比较分析.结果:成功建立了基于蛋白质等电点和疏水性特征的血清蛋白质组差异表达图谱,能够鉴别出56个差异表达蛋白位点,其中12个位点的峰值存在显著差异.结论:蛋白质二维液相色谱是建立血清蛋白质组差异表达谱的有效和可行方法,为维吾尔族妇女宫颈癌患者血清蛋白质标志物的筛选开辟了新的途径.%Objective To establish differential protein expression profile specific for serum proteome of cervical carcinoma in Uighur women by protein 2-dimensional liquid phase chromatogra-phy. Methods We collected and prepared sera of cervical carcinoma from Uighur women, and sepa-rated and processed data using 2-dimensional liquid phase chromatography system specific for protein (ProteomeLabTM PF-2D ). Results A differential expression profile of serum proteome based on characteristics of protein isoelectrie point and hydrophobic features was successfully established. Fifty-six differentially expressed protein spots were found, among which there was an obvious difference in 12 peaks. Conclusion Two-dimensional liquid phase chromatography is an effective and feasible method to establish differential expression profile of serum proteome and to offer a new way for the screening of serum protein markers of Uighur women with cervical carcinoma.
