DNA polymerase ε produces elevated C-to-T mutations at methylated CpG dinucleotides
Nature Genetics ( IF 31.7 ) Pub Date : 2024-10-09 , DOI: 10.1038/s41588-024-01946-w


C-to-T mutations in CpG dinucleotides are widespread in cancers and are also observed in normal cells. By developing and using a technique to quantify DNA polymerase errors (polymerase error rate sequencing, PER-seq), we reveal that C-to-T mutations in CpG dinucleotides constitute part of the error signature of both wild-type and mutant cancer-associated DNA polymerase ε.

DNA 聚合酶 ε 在甲基化 CpG 二核苷酸处产生升高的 C-to-T 突变



CpG 二核苷酸中的 C-to-T 突变在癌症中广泛存在,在正常细胞中也观察到。通过开发和使用一种量化 DNA 聚合酶错误的技术(聚合酶错误率测序,PER-seq),我们揭示了 CpG 二核苷酸中的 C-to-T 突变构成了野生型和突变型癌症相关 DNA 聚合酶ε错误特征的一部分。
