To better illustrate this, a protein–protein interaction (PPI) network was constructed using the STRING database (Search Tool for the Retrieval of Interacting Genes/Proteins) (version 11-5.string-db.org) to explore interactions between mucins and the glioma molecular markers IDH1 and MGMT with query parameters, including the mucins in Figure 1, IDH1, MGMT, and EGFR. Here, MGMT is linked to central nervous system cancer.
