Ferroptosis biomarkers predict tumor mutation burden's impact on prognosis in HER2-positive breast cancer

Figure 2 Identification of candidate genes associated with ferroptosis in the TCGA cohort. A: Heatmap of candidate gene expression differences between tumor and normal tissues; B: Volcano map showing up-regulated and down-regulated genes; C: A Venn diagram to identify differentially expressed genes associated with ferroptosis between tumor and normal tissues; D: Forest plot showing univariate Cox regression analysis results of correlation between candidate gene expression and overall survival.
