In the meta-cohort, univariate Cox regression analysis uncovered that 15 ferroptosis regulators, namely, CRYAB, HSPB1, GLS2, GOT1, FANCD2, CHAC1, PTGS2, ALOX15, ACO1, NFS1, CD44, GPX4, TFRC, TP53, and FADS2 exhibited significant correlations to GC prognosis (Figure 2G; Supplementary Figure S1). This evidence concerns the gene NFS1 and gastric cancer.
