ETV5 expression had significantly positive correlations with CD8+ T cells (rcoad = 0.278, rread = 0.354), CD4+ T cells (rcoad = 0.231, rread = 0.303), macrophages (rcoad = 0.412, rread = 0.515), DCs (rcoad = 0.49, rread = 0.495), and CAFs (rcoad = 0.556, rread = 0.541) both in colon and rectal cancer. The gene discussed is CD4; the disease is rectal cancer.
