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

Figure 6 The immune-related analysis of the four ferroptosis-related prognostic gene signature models in HER2+ breast cancer. A: The Immune cells infiltration of differential risk groups in TCGA; B: Heatmaps represent the correlation between immune cells and prognostic genes; C-E: The immune, stromal, and estimate scores were significantly distinct statistically between low- and high-risk subgroups; F: Expression of immune cell pathways in low- and high-risk subgroups; G:The seven well-known immune checkpoint genes were differentially expressed between low- and high-risk subgroups; H: Correlation chord diagram of 7 immune checkpoints. ^aP < 0.05, ^bP < 0.01, ^cP < 0.001.
