摘要: 目的: 血清蛋白组学在肿瘤标志物的筛查研究中被广泛应用,本研究采用双向荧光差异电泳联合质谱技术,寻找与维吾尔族妇女宫颈鳞癌相关的血浆蛋白候选肿瘤标志物。方法:收集维吾尔族妇女宫颈病变血浆标本 (慢性宫颈炎患者22例,宫颈癌早期患者26例),制备血浆低丰度蛋白质组样品,通过蛋白质双向荧光差异电泳技术分离与鉴别分析,筛选出慢性宫颈炎与宫颈癌早期患者两组间血浆差异表达的蛋白位点,运用质谱和生物信息学技术对其进行鉴定和功能识别分析。结果:确定了宫颈炎和早期宫颈鳞癌患者的血浆低丰度蛋白质组差异荧光电泳图谱,筛选出43个差异表达蛋白位点,通过质谱技术鉴定出16 种蛋白质,在宫颈鳞癌早期患者血浆中有7个蛋白上调表达、9个蛋白下调表达。通过生物信息学分析,差异蛋白涉及的通路主要有补体和代谢相关蛋白和酶类。结论:本研究针对新疆维吾尔族妇女宫颈癌及宫颈炎患者,展开血浆低丰度蛋白组表达水平的研究,鉴定出多种差异表达蛋白质,为宫颈癌的早期诊断及癌变机制研究提供了依据。

Abstract: OBJECTIVE: Serum proteomics in the screening of tumor biomarkers has been widely used. We identified specific plasma candidate tumor biomarkers of cervical squamous cell carcinoma in Uyghur women by two-dimensional differential ingel electrophoresis. METHODS:We collected plasma samples from Uyghur women with cervical lesions and prepared low abundant plasma proteins. After the establishment of a differential proteome profile by two-dimensional differential ingel electrophoresis. mass spectrometry and bioinformatics technology were used to identify and analyze the function of differential proteins. RESULTS:A differential proteome profile was established for Uyghur women with cervicitis and early stage cervical carcinoma. 16 proteins were detected among the 43 differentially expressed between two patient groups,7 were up- regulated and 9 were down- regulated. The primary pathways involved included complement and metabolism-related proteins and enzymes. CONCLUSION:In this study,by focusing on the low abundant plasma proteome biomarker in Uyghur women with high-risk of cervical cancer,we provided evidence for prevention,early diagnosis and carcinogenesis mechanism of cervical cancer in Xinjiang Uyghur women.
