In addition, PDLIM2 showed a significant relationship with dendritic cell markers (HLA-DPB1, HLA-DQB1, HLA-DRA, HLA-DPA1) in BLCA and KIRP, indicating that PDLIM2 is closely related to the infiltration of dendritic cells. This evidence concerns the gene HLA-DPB1 and bladder transitional cell carcinoma.
