Epigenetic regulation including DNA methylation plays an important role in several differentiation processes. We profiled global DNA methylation in the neural differentiation of P19 embryonic carcinoma cells using a microarray-based method called MIAMI. We found a genome-wide demethylation of genes. This suggests demethylation rather than methylation is important in neural differentiation.
包括DNA甲基化在内的表观遗传调控在多个分化过程中发挥着重要作用。我们使用一种名为MIAMI的基于微阵列的方法，对P19胚胎癌细胞神经分化过程中的全基因组DNA甲基化进行了分析。我们发现基因在全基因组范围内发生去甲基化。这表明去甲基化而非甲基化在神经分化中起重要作用。
