Cuproptosis Activation Scoring Model (CuAS) was constructed based on differentially expressed genes among the sample subgroups. A Identification of differentially expressed genes between the two groups based on DESeq2. B Differentially expressed genes were enriched in function by GO-BP analysis. C The KEGG pathway enrichment of differentially expressed genes. D The redundant factors were filtered by the LASSO Cox method to obtain the prognostic marker genes. E Univariate Cox regression was used to identify differentially expressed genes significantly associated with OS. F The contribution of prognostic marker genes to principal components 1 and 2 based on a principal component analysis
