胞嘧啶脱胺和dUMP错掺入已被发现能够在基因组中产生尿嘧啶。这项研究提出了AI-seq(人工结合修饰核碱基测序),一种“碱基取代”,它不仅能够在单核苷酸分辨率上分析尿嘧啶并显示其着丝粒富集,而且还可以揭示鉴定的尿嘧啶位点来自胞嘧啶脱胺。这些结果提示了尿嘧啶作为表观遗传修饰的潜在生物学意义。通过“碱基替代”策略,开发了一种人工掺入修饰的核碱基策略,以在单碱基分辨率下分析全基因组脱氧尿苷。
Deamination of cytosine and dUMP misincorporation have been found to be capable of producing uracil in the genome. This study presents the AI-seq (artificial incorporation modified nucleobase for sequencing), a “base substitution”, which not only is capable of profiling uracil at single-nucleotide resolution and showing its centromeric enrichment but could also reveal that the identified uracil sites are derived from cytosine deamination. All the results indicate the potential biological significance of uracil as the epigenetic modification. An artificial incorporation modified nucleobase strategy was developed to profile genome-wide deoxyuridine at single-base resolution by a “base substitution” strategy.
