结外鼻型NK/T细胞淋巴瘤与T细胞淋巴瘤/白血病细胞株间差异蛋白表达的分析

nalysis of the Differently-Expressed Proteins Among Extranodal NK/T Cell Lymphoma, Nasal Type and T Cell Lymphoma/Leukemia

中文摘要英文摘要

比较结外鼻型NK/T细胞淋巴瘤(Extranodal NK/T Cell Lymphoma, Nasal Type,ENKTCL-N)与T细胞淋巴瘤/白血病(T-cell lymphoma/leukemia)蛋白表达的异同,了解ENKTCL-N蛋白质表达特点,寻找该肿瘤与T细胞淋巴瘤/白血病之间的特异性标志物。运用双向电泳技术对结外鼻型NK/T细胞淋巴瘤细胞株SNK6和T细胞淋巴瘤/白血病细胞株Hut78进行蛋白分离、采用软件结合人工分析,全面比较和筛选ENKTCL-N与T细胞淋巴瘤/白血病细胞株的差异表达蛋白,并行质谱鉴定。利用生物信息学方法初步探讨差异表达蛋白在ENKTCL-N中可能的生物学功能。双向电泳图比较结果显示:两细胞株蛋白点匹配率为75.12%,SNK6细胞株与Hut78细胞株在蛋白表达上有很多相似之处。发现有14对蛋白点存在5倍以上明显表达差异。质谱鉴定和数据库分析得出10个明确差异表达蛋白。其中在SNK6细胞株中上调表达点为4个,4个点为新出现点,2个点为消失点。经蛋白鉴定发现ENKTCL-N与T细胞淋巴瘤/白血病的差异表达蛋白功能主要涉及了细胞分化,细胞增殖和抗凋亡性,血管生成、EB病毒感染等可能的发病机制以及对化疗可能的耐药性等主要方面,为进一步研究该淋巴瘤与T细胞淋巴瘤/白血病之间的特异性标志物,以及在蛋白表达水平上探讨ENKTCL-N发生和演进的机制奠定了基础。

o compare the differently-expressed proteins between ENKTCL-N and T cell lymphoma/leukemia, which was helpful in understanding the characteristics of ENKTCL-N protein expression, finding the characteristic markers for ENKTCL-N to make differetiat diagnosis, and making a foundation for further research of the pathogenesis and progression of ENKTCL-N in the protein level. The differently-expressed proteins had been isolated by 2-DE, compared and analyzed by software and by handwork, and identified by mass spectrometry (MS)between ENKTCL-N cell line SNK6 and T cell lymphoma/leukemia cell line Hut78. The 2-DE comparison results of ENKTCL-N cell line SNK6 and T cell lymphoma/leukemia cell line Hut78 showed that the match rate of the two cell lines was 72.15%, which suggested that there were many similarities between ENKTCL-N cell line SNK6 and T cell lymphoma/leukemia Hut78. Fourteen pairs of 5-fold different protein spots had been detected, from which 10 proteins had been identified by MS and protein-database. In Hut78 cell line, four proteins were up-regulated, four proteins were newly-appeared and two disappeared. The differently-expressed proteins between ENKTCL-N cell line SNK6 and T cell lymphoma/leukemia cell lines were mainly involved cell differentiation, and proliferation, anti-apoptosis, angiogenesis, EB virus infection, chemotherapy resistance, and so on, which was helpful in trying to find the special markers between ENKTCL-N and T cell lymphoma/leukemia, and set up an essential foundation for deep research of the pathogenesis and progression of ENKTCL-N in the protein level.
