Based on the 10 DE-CRGs, we furtherly performed LASSO analysis and SVM-RFE analysis and identified 5 DE-CRGs as marker genes, including F5, MT4, RNF7, S100A12, and SORD, which had an excellent diagnostic performance.
Cuproptosis-related genes were manually curated, and differentially expressed cuproptosis-related genes (DECuGs) were identified.Then, the 16 DECuGs were obtained by the intersection of the 5018 DEGs and 63 cuproptosis-related genes.
Cuproptosis-related gene sets were obtained from a previous study [9] and combined with the Molecular Signature Database (MsigDB) v7.0 database (http://www.gsea-msigdb.org/gsea/msigdb/, GOBP_CELLULAR_COPPER_ION_HOMEOSTASIS, GOBP_CELLULAR_RESPONSE_TO_COPPER_ION).
