Several significantly differentially methylated probes correspond to genes involved in cancer-related mechanisms such as cell death (MCF2L, RASSF5, RASSF6, CASZ1, SLC22A18, IFI27), tumorogenesis (CTSZ, TP73, CTSK, PIK3R1), KLK11, cell cycle (PPM1G, RANBP5, VAMP8) and cell differentiation (SMAF1, PAX6, PAX8). This evidence concerns the gene CTSK and cancer.
