Fig. 1From: Identification of a ferroptosis-related gene signature predictive model in colon cancerIdentification of candidate FRGs in TCGA cohort. a Venn diagram to identify ferroptosis-related DEGs between tumor and adjacent normal tissue that were correlated with OS. b Forest plots showing the results of univariate Cox regression analysis between the expression of 10 candidate FRGs and OS. c Heat map showing the expression of 10 candidate FRGs in normal and tumor colon tissue. d Mutation information of prognosis-related FRGs; TFAP2C was the most frequently mutated gene, and five genes had a mutation rate ≥ 3%Back to article page
