TP53 and adrenal cortex carcinoma: Besides, the other 5 hub ferroptosis-associated genes (TP53, HELLS, ACSL4, PCBP2, and HMGB1) included in the signature also showed significant correlation with the infiltrating levels of B cells (r = 0.159 to 0.387, p < 0.001), CD8+ T cells (r = −0.078 to 0.211, p < 0.001), CD4+ T cells (r = −0.019 to 0.293, p < 0.001), macrophages (r = −0.155 to 0.304, p < 0.001), neutrophils (r = 0.044 to 0.257, p < 0.001), and DCs (r = 0.206, p < 0.001) in ACC (Figures 6(b)–6(f)).
