SNAI2 and head and neck squamous cell carcinoma: Consistently, CBR1 inhibition resulted in increased in vitro invasion ability of several HNSCC cell lines and in the activation of several EMT markers, such as vimentin, CDH1, or the zinc finger protein SNAI2 (SNAI2) [346], indicating that the Wnt signalling pathway could have a pro-metastatic role.
