微卫星突变表型(MMP)是肿瘤细胞基因组中数十万个微卫星序列中重复单位数量的变化,是多种肿瘤(包括散发性和遗传性非息肉病结肠癌)致癌的基础。这种增强的微卫星不稳定性是通过对结肠癌 DNA 进行任意引物聚合酶链式反应 (AP-PCR) 指纹识别发现的。在这项研究中,我们发现了一种任意引物,可以扩增多个含有重复序列的 DNA 片段,包括人类基因组 Alu 重复中发现的多聚 A 片段。结合使用荧光引物标记和 AP-PCR 产品的自动 DNA 测序分析 (FAP-PCR),检测到先前确定属于 MMP 的所有 DNA 样本中指纹带的变化。使用这种单一任意引物的荧光 AP-PCR 指纹分析提供了一种方便有效的方法来检测传统指纹分析通常无法检测到的肿瘤特异性指纹变化。
The microsatellite mutator phenotype (MMP), detected as a change in the number of repeating units in hundreds of thousands of microsatellite sequences in the tumor cell genome, underlies the carcinogenesis of a variety of tumors including sporadic and hereditary nonpolyposis colon cancers. This enhanced microsatellite instability was discovered using arbitrarily primed polymerase chain reaction (AP-PCR) fingerprinting of DNA from colon cancers. In this study, we found an arbitrary primer that can amplify multiple DNA fragments containing repeated sequences, including the poly A tracts found in the Alu repeats of the human genome. The combined use of primer labeling with fluorescence and an automated DNA sequencing analysis of AP-PCR products (FAP-PCR) detected alterations in fingerprint bands in all DNA samples previously determined to belong to the MMP. Fluorescent AP-PCR fingerprinting using this single arbitrary primer provides a convenient and efficient method for detecting tumor specific fingerprint alterations that are usually undetectable by conventional fingerprinting.
