TEAD4 and head and neck squamous cell carcinoma: Noticeably, our results also indicated that TEAD4 promoted invasion and motility by facilitating EMT in HNSCC as evidenced by morphological alternations and EMT marker changes upon TEAD4 depletion and overexpression, its critical role during TGF-β1-induced EMT as well as positive association between TEAD4 expression and cervical node metastasis.
