ZFHX4 and bladder transitional cell carcinoma: Furthermore, we analyzed the correlation between these six homeobox genes and tumor size, regional lymph node involvement, and distant metastases (TNM) as well as the BLCA stage and found that TSHZ3, ZFHX4, and ZEB2 were positively correlated with T stage, N stage, and BLCA stage, but there was no significant correlation with metastasis (Figures 3B–E).
