人BRIT1基因在宫颈癌组织中的表达及其临床意义分析

目的检测宫颈癌组织和配对的宫颈非癌组织中的BRIT1表达情况,比较两者之间的表达差异。方法分别应用实时荧光PCR(RT-PCR)、免疫组化技术检测宫颈癌组织及其配对的宫颈非癌组织中BRIT1 mRNA和蛋白的表达水平,分析BRIT1蛋白表达水平与患者年龄、肿瘤大小、肿瘤类型、肿瘤的病理分级和临床分期之间的关系。结果 RT-PCR结果揭示宫颈癌组织中BRIT1mRNA的表达水平低于配对的宫颈非癌组织,差异有统计学意义(P0.05);免疫组化技术结果揭示63例标本中的44例(69.8%)宫颈癌组织BRIT1蛋白表达水平低于配对的宫颈非癌组织,差异有统计学意义(P0.05);在高级的病理分级和临床分期中,BRIT1蛋白的表达减少更为明显。结论 BRIT1在宫颈癌癌组织和非癌组织中的表达差异提示BRIT1可能在宫颈癌的发生、发展中具有一定的作用。

Analysis of human BRIT1 expression and its clinical significance in cervical cancer

Objective To detect the expression of BRIT1 in cervical cancer tissues and cervical noncancer tissues ,and to analyze the differences between the two tissues .Methods The expression of BRIT1 mRNA and protein in cervical cancer tissues and the paired cervical noncancer tissues was evaluated by RT‐PCR and immmunohistochemistry .Its correlation with the clinicopathological parameters including age ,tumor types ,size ,tumor pathological grade and clinical stage was analyzed .Results RT‐PCR results showed that the BRIT1 mRNA level in cervical cancer tissues was significantly lower than that in the paired cervical noncancer tis‐sues ,the difference was statistically significant (P<0 .05) .The immmunohistochemistry results showed that the BRIT 1 protein ex‐pression level in 44 cases of 63 (69 .8% ) samples wa slower than that in the paired cervical noncancer tissues ,the difference was statistically significant(P<0 .05);In high pathological grades and high clinical stages ,the decrease of BRIT1 protein expression was more significant .Conclusion The difference of the BRIT1 expression between the cervical cancer tissues and cervical noncancer tis‐sues suggests that BRIT1 may play a certain role in the occurrence and development of cervical cancer .
