在哺乳动物基因组中,5 '-CpG-3'二核苷酸经常被甲基化,与转录沉默相关。全基因组去甲基化被认为在发育过程中只发生两次,在原始生殖细胞和植入前胚胎中。这些去甲基化事件之后是从头甲基化,建立了一种在整个发育过程中遗传的模式,并且仅在组织特异性基因座处进行修饰。在这里,我们研究了DNA甲基化在分化小鼠成红细胞在体内使用基因组规模减少代表亚硫酸氢盐测序(RRBS)。红系特异性β-珠蛋白基因座的去甲基化与大多数基因组元件的整体DNA去甲基化一致。整体去甲基化在整个分化过程中是连续的,需要快速的DNA复制。因此,DNA去甲基化可以在体细胞分化过程中全面发生,为研究其在发育和疾病中的作用提供了实验模型。
In the mammalian genome, 5’-CpG-3’ dinucleotides are frequently methylated, correlating with transcriptional silencing. Genome-wide demethylation is thought to occur only twice during development, in primordial germ cells and in the pre-implantation embryo. These demethylation events are followed by de novo methylation, setting up a pattern inherited throughout development and modified only at tissue-specific loci. Here we studied DNA methylation in differentiating mouse erythroblasts in vivo using genomic-scale reduced representation bisulfite sequencing (RRBS). Demethylation at the erythroid-specific β-globin locus was coincident with global DNA demethylation at most genomic elements. Global demethylation was continuous throughout differentiation and required rapid DNA replication. Hence, DNA demethylation can occur globally during somatic cell differentiation, providing an experimental model for its study in development and disease.
