In skeletal muscle, DNA methylation contributes to the suppression of gene expression in several biological processes and diseases. A protocol for the detection of methylated cytosine was thus established based on methylation-sensitive enzymes, immunoprecipitation, and bisulfite conversion. DNA methylation analysis, with bisulfite conversion and sequencing, enables the quantification of methylation at each single base position. Here, we describe a basic method of bisulfite sequencing that can be used to analyze local DNA methylation status to confirm genome-wide DNA methylation analysis or correlation of gene expression regulatory mechanisms.
在骨骼肌中，DNA甲基化在多个生物学过程和疾病中有助于基因表达的抑制。因此，基于甲基化敏感酶、免疫沉淀和亚硫酸氢盐转化建立了一种检测甲基化胞嘧啶的方案。通过亚硫酸氢盐转化和测序进行的DNA甲基化分析能够对每个单碱基位置的甲基化进行定量。在此，我们描述了一种亚硫酸氢盐测序的基本方法，可用于分析局部DNA甲基化状态，以确认全基因组DNA甲基化分析或基因表达调控机制的相关性。
