Methylation analysis of repetitive elements in mouse. (A) Methylation profiles of LINE-1, SINE B1, and major satellite DNA by pyrosequencing analysis. (B) Association of the methylation percentages between LINE-1 (y-axis), SINE B1 (x-axis), and major satellite DNA (x-axis) in all samples. Sample codes are on the right. The Spearman test was used to determine correlations, with significance set at P < 0.05. R represents a measure of the linear relationship between two variables, and varies from −1 to +1.
