摘要
目的:探讨乳腺癌基因(BRCA1)在遗传性卵巢癌发生、发展中的作用,并分析BRCA1 基因杂合性丢失(LOH)。方法:应用多聚合酶链反应技术(PCRT),对10份遗传性卵巢癌组织中BRCA1 基因内部的D17S855 微卫星位点进行LOH检测。结果:2份发生杂合性丢失,LOH发现率为20% 。结论:BRCA1在遗传性卵巢癌中具有肿瘤抑制基因的作用,同时不能排除其他肿瘤抑制基因的作用。
Objective:To evaluate the role of BRCA1 gene in the development and progress of hereditary ovarian cancer,and to investigate the loss of heterozygosity(LOH)at the BRCA1 genetic loci,D17S855.Methods:Using the polymerase chain reaction technique(PCRT),LOHs in 10 samples of hereditary ovarian cancer at intragenic loci were detected.Results:Only 2/10 samples(20%) had LOH.Conclusions:BRCA1 is a tumor surpressor gene in hereditary ovarian cancer,but other tumor supressor genes may also exist.
