Interestingly, despite the fact that the number of tumor‐infiltrating T cells was increased in high HMOX1 signature samples (Spearman's ρ = 0.45, p = 0.004, Figure 5B), CD8+ T cells, CD4+ T cells, Tregs, and macrophages were not associated with HMOX1 signature. The gene discussed is CD8A; the disease is neoplasm.
