在哺乳动物细胞中,胞嘧啶(5mC)第5位DNA甲基化作为表观遗传标记起着重要作用。然而,在线虫中,DNA甲基化被认为是不存在的,因为缺乏可检测到的5mC以及胞嘧啶DNA甲基转移酶的同源物。在这里,我们使用多种方法,证明了线虫DNA中腺嘌呤N6-甲基化(6 MA)的存在。我们进一步证明,在表观遗传的范例中,这种修饰会跨代增加。重要的是,我们鉴定了一个DNA去甲基酶NMAD-1和一个潜在的DNA甲基转移酶DAMT-1,它调节组蛋白H3K4me2和6 mA甲基化之间的6 mA水平和串扰,并控制与H3K4me2去甲基酶spr-5缺失相关的表观遗传。总之,这些数据确定了线虫的DNA修饰,并提出了6 mA可能是真核生物中可遗传表观遗传信息的载体的令人兴奋的可能性。
In mammalian cells, DNA methylation on the 5th position of cytosine (5mC) plays an important role as an epigenetic mark. However, DNA methylation was considered to be absent in C. elegans because of the lack of detectable 5mC as well as homologs of the cytosine DNA methyltransferases. Here, using multiple approaches, we demonstrate the presence of adenine N6-methylation (6mA) in C. elegans DNA. We further demonstrate that this modification increases trans-generationally in a paradigm of epigenetic inheritance. Importantly, we identify a DNA demethylase, NMAD-1, and a potential DNA methyltransferase, DAMT-1, which regulate 6mA levels and crosstalk between methylation of histone H3K4me2 and 6mA, and control the epigenetic inheritance of phenotypes associated with the loss of the H3K4me2 demethylase spr-5. Together, these data identify a DNA modification in C. elegans and raise the exciting possibility that 6mA may be a carrier of heritable epigenetic information in eukaryotes.
