IDH1 and glioma: 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.
