B4GALT1 expression in MIBC was associated with tumor immunosuppressive status. No differences between B4GALT1 expression (low vs. high) and CD8+ T cell infiltration density (number/cm²) within tumor cores in Zhongshan cohort (a), FUSCC cohort (b) and TCGA_BLCA cohort calculated by CYBERSORT method (c); the positive Pearson correlation between B4GALT1 and PD-L1 expression (d) and CTLA4 expression (e) in TCGA dataset
