Expression of CTAs in triple-negative breast cancer data from TCGA database. A Heatmap of 56 CTAs in triple-negative breast cancer data from TCGA database. B Volcano plot of differentially expressed genes in triple-negative breast cancer and adjacent cancer data from TCGA database. C Venn diagram of the intersection of 276 CTAs and upregulated genes in triple-negative breast cancer data from TCGA database. D Venn diagrams were used to screen for CTAs with higher expression in overall breast cancer than in adjacent tumors and with higher expression in triple-negative breast cancer than in adjacent tumors. E Protein–protein interaction network diagram of 41 CTAs. F: Screening of hub genes among 41 CTAs
