Figure 5. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis and correlation between DBT and related genes. (A) STRING protein–protein association networks of DBT. (B) KEGG pathway analysis of DBT. (C) Correlation of DBT and related genes. (D) Differential expression of copper apoptosis-related genes (CRGs) in a cohort of resistant RCC. (E) Different colors represent data from different datasets. Overlapping regions correspond to shared differentially expressed CRGs.
