The genes displaying the strongest inverse correlation included four genes related to cancer processes: SERPINB1 (Figure 4), which promotes cancer cell motility in invasive oral squamous cell carcinoma [26], EMP3, which displays regulation through promoter methylation in gliomas [27], FABP5, which mediates EGFR-induced carcinoma cell growth [28], and CBR1, which is involved in tumor progression [29,30]. This evidence concerns the gene EGFR and central nervous system cancer.
