By univariate Cox analysis, 15 ferroptosis-related genes (AKRIC1, FANCD2, GCLM, GLS2, GPX4, HSPB1, MT1G, SLC7A11, TFRC, STEAP3, SQLE, FADS2, NQO1, NOX1, and HMOX1) were found to be associated with renal cancer patient outcomes, as detailed in Figure 4. This evidence concerns the gene HMOX1 and renal carcinoma.
