BCL7B and bladder transitional cell carcinoma: The outcomes indicated that BCL7B gene expression was positively correlated with the expression of B cells (p = 0.011), dendritic cells (p = 0.020), neutrophils (p < 0.001), T cells (p = 0.001), macrophages (p < 0.001), and NK cells (p < 0.001) in BLCA (Figure 3A).
