Fig. 3From: Estimating breast tissue-specific DNA methylation age using next-generation sequencing dataVolcano plots of differentially methylated clock CpGs in pairwise comparisons a adjacent-normal (N) vs normal (K); b tumor (T) vs normal (K); and c tumor (T) vs adjacent-normal (N) breast tissue. Differentially methylated clock CpGs (in cyan) are identified if |∆β| > 0.1 and t test p < 0.05Back to article page
