Figure 5. Correlation of FDX1 expression with immune status. (A–D) Association between FDX1 expression and ESTIMATE, stromal, and immune scores and tumor purity. (E, F) Immune cell infiltration levels and immune-related function in high- and low-FDX1 expression groups. (G) Differences in expression of immune checkpoint genes between high- and low- FDX1 expression groups. (H) Correlation between FDX1 and immune subtypes.
