<p>Schematic summary of CpG sites in the miR-124-1, miR-124-2 and miR-124-3 promoter regions. (A) Methylation analysis was done in 10 clones from each cell line. Each row of circles represents a single clone, and each circle represents a single DNA methylated or demethylated site. (B) The methylation percentages of 10 clones from each of the cell lines are summarized in the bar graph. Data are shown as the means ± SEM. Asterisks indicate P<0.05, double asterisks indicate P<0.001.</p
