摘要 人类肿瘤的发生和发展常与非随机性染色体异常(包括基因组缺失、获得、扩增和重排等)有关[1,2].比较基因组杂交(comparatlve genomlc hybridization,CGH)技术可以快速全面地分析肿瘤组织DNA拷贝数的变化,并在中期染色体上定位,对于肿瘤研究具有重要意义.但是,CGH至今未应用于临床,一个主要的障碍是使用中期染色体铺片作为杂交靶,其局限性为:⑴CGH的分辨率低,不能发现小于2Mb的DNA获得和缺失;⑵不能将DNA拷贝数变化与基因或基因标记物直接联系起来;⑶虽然可经计算机软件识别每条染色体,但仍需要经验丰富的人员进一步确定,这限制了CGH的自动化操作和高通量分析[3~5].为了克服CGH的局限性,人们发明了微阵列一比较基因组杂交(array-CGH,matrix-CGH)技术,将DNA克隆或cDNAs做成微阵列,代替中期染色体作为杂交靶,不仅使分辨率提高,甚至可以确定肿瘤相关基因并提供精确的定位[3,4,6~8].
