Figure 6. Identification of cuproptosis-related novel genes and their potential characteristics. (A) Identification of cuproptosis-related novel genes using PPI network. Purple represented known cuproptosis regulators, blue represented novel cuproptosis regulators, and green represented indirect cuproptosis regulators. (B) Forest plot of novel cuproptosis regulators using univariate Cox regression analysis in merge cohort (GSE7696, GSE16011, GSE108474, ArrayExpress-E-TABM-898). (C–H) Kaplan-Meier survival curves for patients of GBM with high and low gene expression in merge dataset (GSE7696, GSE16011, GSE108474, ArrayExpress-E-TABM-898).
