许多谱系特异性基因在干细胞中保持平衡并沉默。分化后,与自我更新和替代谱系相关的基因稳定沉默。近端启动子的CpG甲基化和PRC 2介导的H3 K27 me 3在暂时或永久沉默基因中发挥作用,分别与或不与活性表观遗传标记共存。有趣的是,在转录起始位点远端的神经元基因上的DNA甲基化由于其排斥PRC 2介导的抑制的能力而使转录激活成为可能。此外,DNA去甲基化酶泰特蛋白在分化过程中调节DNA甲基化和相关H3 K27 me 3的变化中发挥作用。总的来说,由H3 K4 me 3、组蛋白乙酰化/去乙酰化、H3 K27 me 3和DNA甲基化/去甲基化形成的复杂的表观遗传网络共同作用以调节干细胞自我更新和分化。
Many lineage-specific genes are poised and silenced in stem cells. Upon differentiation, genes that are related to self-renewal and alternative lineages are stably silenced. CpG methylation at proximal promoters and PRC2-mediated H3K27me3 play a role in silencing genes temporarily or permanently, with or without coexistence of active epigenetic marks, respectively. Interestingly, DNA methylation on neuronal genes that is distal to transcription start site enable transcription activation owing to its ability to repel PRC2-mediated inhibition. In addition, DNA demethylase Tet proteins play a role in regulation of changes in DNA methylation and related H3K27me3 during differentiation. Collectively, a complex epigenetic network formed by H3K4me3, histone acetylation/deacetylation, H3K27me3 and DNA methylation/demethylation act together to regulate stem cell self-renewal and differentiation.
