Cuproptosis-related long non-coding RNAs model that effectively predicts prognosis in hepatocellular carcinoma

Figure 5 Visualization of expression levels of the three component long-chain non-coding RNAs of the cuproptosis-related long-chain non-coding RNA signature (CupRLSig) model based on clinicopathological variable stratification and principal component analysis of different gene sets performed for classification of patient risk. A: Heatmaps of expression of the three long-chain non-coding RNAs (lncRNAs) and clinical characteristics for different risk groups; B-E: PCA of low- and high-risk groups based on (B) whole-genome genes, (C) cuproptosis-related genes, (D) cuproptosis-related lncRNAs, and (E) cuproptosis-related lncRNA signature (CupRLSig) model risk lncRNAs. Patients with high risk scores are denoted by red, while those with low risk scores are denoted by blue. N: Lymph node metastasis; M: Mistant metastasis; T: Tumor.
