Differential expression analysis. (A, B) Volcano and heatmaps for DEGs in GSE30655. (C) Venn diagram showing DEGs intersecting with ferroptosis-related genes. Bar plot showing GO (D) as well as KEGG analysis (E) on DEFRGs. (F) PPI network for DEFRGs and (G) distinct gene module obtained from the PPI network. (H) Functional similarity analysis. Horizontal and vertical axes represent similarity score and genes, respectively. GO, Gene Ontology; KEGG, Kyoto Encyclopedia of Genes and Genomes; PPI, protein–protein interaction
