FZD7 and neoplasm: According to the previous literatures, FZD7 was a new prognostic indicator, which promoted tumour metastasis through the WNT and epithelial‐to‐mesenchymal transition (EMT) signalling pathways in oesophageal squamous cell carcinoma.18 FZD7 K‐O inhibited cell growth and metastasis and promoted chemosensitivity of oesophageal squamous cell carcinoma cells by inhibiting the Wnt signal transduction.
