CD8A and bladder transitional cell carcinoma: We observed positive correlation between Fam20C expression and infiltrating levels of CD8+ T cells (R, 0.269; P, 1.83e-07), CD4+ T cells (R, 0.28; P, 5.51e-08), macrophages (R, 0.468; P, 3.20e-21), neutrophils (R, 0.321; P, 3.64e-10), and DCs (R, 0.395; P, 4.74e-15) in BLCA (Figure 6).
