The center nodes of the networks, some interesting genes, were observed, such as PTEN, AKT, ATM, TGFβ, PI3K, CCND2, HEY2, CDK2, and FDX1. In addition, the cBioPortal was used to provide visualization, analysis of DEGs related to the ovarian cancer from large-scale cancer genomics data sets (Supplementary Figures S2C, S3). Here, CDK2 is linked to ovarian carcinoma.
