Prognostic implications of ferroptosis-associated gene signature in colon adenocarcinoma

Figure 2 Identification of the candidate prognostic ferroptosis-related genes in the Cancer Genome Atlas-colon adenocarcinoma cohort. A: Venn diagram to confirm differentially expressed genes between corresponding adjacent normal tissue and tumor tissue related to overall survival; B: Heatmap of the seven prognostic ferroptosis-related gene expression profiles in the Cancer Genome Atlas-colon adenocarcinoma cohort; C: Forest plots demonstrated the results of the univariate Cox regression analysis between the expression of the seven prognostic ferroptosis-related genes and overall survival; D: PPI network obtained from the STRING database indicated the interactions among the candidate genes; E: Correlation network of candidate genes. The correlation coefficients are shown using different colors. DEGs: Differentially expressed genes.
