Interestingly, the enrichment analysis (Figure 7) did not highlight any of the commonly disrupted pathways (e.g., ARF-MDM2-p53, NRF2-KEAP1 and PI3K pathways) found in most cancers, despite our initial comparative analysis, which suggested the hypermethylation of associated genes across the four canonical pathways in this manuscript (Section 3.1). This evidence concerns the gene PIK3CG and cancer.
