Figure 3. Differences among age groups. (A, B) Testis and muscle tissue sections with HE and ATPase staining, respectively. (C, D) The distribution of autosomal DMCpGs between any two age groups. From outside to inside, density plot show the results of six differential analyses under 9vs1Ymuscle, 9vs1Ytestis, 9vs4Ymuscle, 9vs4Ytestis, 4vs1Ymuscle, and 4vs1Ytestis, respectively. (E) GO terms for genes with highly dynamic CpGs which were shared in two tissue.
