Comprehensive analysis of new prognostic signature based on ferroptosis-related genes in clear cell renal cell carcinoma


Figure 4. Experimental verification of four genes in the prognostic signature. (AH) Immunohistochemical images of expression of the four proteins from the prognostic signature in non-tumor tissue samples (A, C, E, G) and tumor samples (B, D, F, H). (I) mRNA expression levels of 4 ferroptosis-related genes were evaluated using qRT–PCR in ccRCC samples and normal samples. *, P < 0.05; **, P < 0.01; ***, P < 0.001.
