It was found that these genes were enriched in the biological processes related to glioma, which included basic cancer-related biological processes, as well as glioma-related specific biological processes, including mitotic recombination, DNA metabolism, and ErbB2 signaling pathway (Figure 3D), suggesting that the methylation sites revealed in this study might affect gliomagenesis and development. This evidence concerns the gene ERBB2 and glioma.
