The results revealed a significant connection between IFI30 expression levels and the levels of cell purity infiltration (r ═ 0.239, P ═ 2.8e-07), B cells (r ═ 0.398, P ═ 6.86e-19), CD8+ T cells (r ═ 0.22, P ═ 1.41e-02), CD4+ T cells (r ═ 0.114, P ═ 1.41e-02), macrophages (r ═ 0.431, P ═ 1.20e-21), neutrophils (r ═ 0.408, P ═ 8.35e-20), and dendritic cells (r ═ 0.557, P ═ 1.07e-41) in ccRCC (Figure 6), where P < 0.05 was reported as differentiable. The gene discussed is CD4; the disease is nonpapillary renal cell carcinoma.
