1、血浆miRNA在鼻咽癌发生发展中的表达差异性研究 摘要 目的 应用miRNA芯片技术,探讨血浆miRNA在鼻咽癌发生、发展中的表达差异性,初步筛选出与鼻咽癌相关的miRNA,为鼻咽癌早期发觉、早期诊断、早期治疗供应依据。 方法 选取90例初次接受治疗的鼻咽癌患者及健康成年人60例,分别收集全部探讨对象的血浆标本,分别miRNA,运用GenePix4000B芯片行比较分析病例组与比照组之间miRNA的表达是否存在差异。 结果 通过比较,各组一般资料无差异,90例鼻咽癌患者临床分期为期组20例,期组20例,期组25例,期组25例;通过miRNA芯片检测发觉差异表达miRNA31个,在这31个miR
2、NA中,上调有26个,下调有5个,差异具有统计学意义。 结论 鼻咽癌患者和健康人血浆中含有的miRNA表达存在差异,提示miRNA参与到鼻咽癌病情的发生以及发展当中,可为鼻咽癌的早期发现,早期诊断,早期治疗提供理论依据。 关键词 鼻咽癌;miRNA;表达;差异性 中图分类号 R739.63 文獻标识码 A 文章编号 2095-061609-217-03 Differential expression study of plasma miRNA in the occurrence and development of nasopharyngeal carcinoma LUO Fengling D

5、d.Plasma samples were collected from all subjects to separate the miRNA.GenePix4000B chip was used to compare and analyze the differential expression of case group and control group. Results By comparison,there was no difference in general data.90 patients with nasopharyngeal carcinoma were divided
6、into stage I group,stage II Group,stage III groupand stage IV group.There were 31 cases different in the expression of miRNA by miRNA.Among the 31 cases of miRNA,there were Up by 26,down by 5,and the difference was statistically significant. Conclusion The expression of miRNA in plasma of NPC patien

8、我国南方地区最常见的恶性肿瘤之一,以明显的区域分布特征、剧烈的转移倾向为显著特征1。大宗临床病例视察显示鼻咽癌病人不易早期发觉2。而有关鼻咽癌的分子标记物探讨中,EB病毒VCA-IgA、EA-IgA及血液中EBV-DNA拷贝数改变虽然在肯定程度上可监测鼻咽癌疗效,但目前还没有被FDA承认的鼻咽癌诊断及预料预后的分子标记物3。如何能够早期发觉、预料肿瘤对治疗的敏感性、预料预后、监测复发或转移对鼻咽癌诊治、干预具有重要的临床意义。然而,正常状况下血浆中存在miRNA,可能为细胞、组织、器官之间的信息传递方式,一般正 常人群的血浆miRNA表达谱改变不大,肿瘤细胞也可通过微泡主动释放miRNA入血,
