Construction of the copper homeostasis-related gene prognostic model in TCGA dataset. (A) The 51 copper homeostasis-related genes in LASSO regression. (B) Cross-validation for tuning the parameter selection in the LASSO regression. (C) Forest plot of hazard rates of the six copper homeostasis-related genes. (D) The messenger RNA levels of the copper homeostasis-related genes in glioma and normal tissues. (E) Venn diagram showing the intersection. (F-G) Kaplan-Meier curves were used to compare OS in TCGA and CGGA datasets. *, P<0.05; **, P<0.01; ***, P<0.001. TCGA, The Cancer Genome Atlas; LASSO, least absolute shrinkage and selection operator; CGGA, Chinese Glioma Genome Atlas; OS, overall survival; AIC, Akaike Information Criterion.
