【摘要】:正DNA甲基化的形式主要包括以下3种:5-甲基胞嘧啶(5mC)、N~6-甲基嘌呤(N6mA)以及7-甲基鸟嘌呤(7mG)~([1])。目前,研究得最为广泛也最为透彻的就是主要存在于CpG岛中胞嘧啶的甲基化修饰,即5mC。在哺乳动物基因组中大约有70%~80%的CpG岛区域的胞嘧啶存在甲基化修饰~([2])。而CpG岛的甲基化是基因沉默的一个重要标志,在调控基因
[Abstract]:There are three main forms of methylation of DNA: 5-methylcytosine (5mC), N-methyl-6-methylpurine (N6mA) and 7-methylguanine (7mG) ~ (1). At present, the most widely studied and thoroughly studied is the methylation modification of cytosine that mainly exists in CpG island, that is, 5mC. About 70% of the CpG island region in mammalian genome contains methylation modification of cytosine ([2]). Methylation of CpG island is an important marker of gene silencing.
