Principal component analyses (PCA) and representative results of functional enrichment analysis. PCA showing the distribution differences between the high- and low-risk groups using cuproptosis-related genes (A), cuproptosis-related lncRNAs (B) and risk-associated lncRNAs (C). (D&E) GO analysis of biological functions of differentially expressed genes between the high- and low-risk groups. (F&G) KEGG analysis of biological functions of differentially expressed genes between the high- and low-risk groups.
