The majority of the aging DEGs were also found in cancer, including, for example, the CKM gene, which contained a dmCpG in the proximity of its promoter (Figure 7b), was differentially expressed in both processes (Figure 7c) and displayed a considerable negative correlation between DNA methylation and gene expression in normal kidney (Spearman r = −.37, Figure 7d). Here, CKM is linked to cancer.
