To investigate whether epigenetic silencing of Wnt inhibitory factor-1 occurs in bladder tumors and examine its role in activating the canonical Wnt/beta-catenin pathway.
Evaluated CpG hypermethylation status of the Wif-1 promoter in bladder tumor specimens.
Assessed aberrant activation of canonical Wnt/beta-catenin signaling linked to WIF-1 epigenetic inactivation.
CpG hypermethylation of the Wif-1 gene promoter occurred frequently in bladder tumor specimens.
Hypermethylation-mediated inactivation of WIF-1 contributed to bladder cancer pathogenesis via abnormal activation of the canonical Wnt/beta-catenin signaling cascade.
