Table 1. The frequency of WIF-1 methylation in tumor tissue and healthy adjacent tissue.
WIF-1 methylation status | Cancerous tissue, n = 50 n (%) | Healthy tissue, n = 50 n (%) |
---|---|---|
UU | 22 (44.0) | 46 (92.0) |
UM | 2 (4.0) | 0 (0.0) |
MM | 26 (52.0) | 4 (8.0) |
p < 0.001; χ2 = 260.60
WIF-1: Wnt inhibitory factor-1; U: unmethylated; M: methylated.
