HAMP and bladder transitional cell carcinoma: Figures 4B–E show different expression patterns of hepcidin between low- and high-risk groups in BLCA (Figure 4B), KIRC (Figure 4C), KIRP (Figure 4D), and PRAD (Figure 4E) that were calculated by SurvivalMeth. The heatmap revealed the CpG methylation level of hepcidin in BLCA (Figure 4B), KIRC (Figure 4C), KIRP (Figure 4D), and PRAD (Figure 4E) which are based on TCGA database.
