To determine how TET1 influenced Wnt/β-catenin signaling, the expression of Wnt pathway antagonists, including DACT (DACT1,2,3), SFRP (SFRP1,2,3), DKK (DKK1-3) family genes, and WNT proteins (include WNT1,3,3A,4, WAN5A, WNT5B, WNT7A, WNT7B) in HNSN (head and neck squamous cell normal tissues) and HNSC (head and neck squamous cell carcinoma) was analyzed. This evidence concerns the gene WNT1 and head and neck squamous cell carcinoma.
