The E2F7 expression was remarkably positively related to tumor purity (r = 0.151, P = 9.03e − 04), B cells (r = 0.222, P = 9.06e − 07), CD8+ T cells (r = 0.279, P = 5.13e − 10), macrophages (r = 0.199, P = 1.29e − 05), and DCs (r = 0.175, P = 1.22e − 04) in LGG (Figure 7(g)). The gene discussed is E2F7; the disease is neoplasm.
