Figure 2. Acquisition and enrichment analysis of LUAD-related CRFGs. (A) Volcano plot, blue dots indicate genes significantly down-regulated in expression in LUAD samples compared to normal samples, and red dots indicate genes significantly up-regulated. (B) Heat map. (C) PPI network diagram of CRFGs, ferroptosis-related genes are shown with pink nodes and green nodes representing cuproptosis-related genes. (D) Venn diagram constructed by LUAD and CRFGs. (E) GO and KEGG enrichment analysis of LUAD-related CRFGs, with the longer columns representing higher enrichment.
