    • Bottleneck Sequencing System (BotSeqS) is a next-generation sequencing method that simultaneously quantifies rare somatic point mutations across the mitochondrial and nuclear genomes. BotSeqS combines molecular barcoding with a simple dilution step immediately prior to library amplification. BotSeqS can be used to show age and tissue-dependent accumulations of rare mutations and demonstrate that somatic mutational burden in normal tissues can vary by several orders of magnitude, depending on biologic and environmental factors. BotSeqS has been used to show major differences between the mutational patterns of the mitochondrial and nuclear genomes in normal tissues. Lastly, BotSeqS has shown that the mutation spectra of normal tissues were different from each other, but similar to those of the cancers that arose in them.
    • 瓶颈测序系统(BotSeqS)是一种新一代测序方法,可同时量化线粒体和核基因组中的罕见体细胞点突变。 BotSeqS在文库扩增之前将分子条形码与简单稀释步骤结合在一起。 BotSeqS可以用于显示年龄和组织依赖性罕见突变的累积,并且证明正常组织中的体细胞突变负荷可以根据生物和环境因素而变化几个数量级。 BotSeqS已被用于显示正常组织中线粒体和核基因组的突变模式之间的主要差异。 最后,BotSeqS已经表明,正常组织的突变谱彼此不同,但与它们中出现的癌症的突变谱相似。
