S100A7 and squamous cell carcinoma: Our recent data show YAP as a suppressor in S100A7 induction in epidermoid carcinoma cells.[13] Since the upregulation of S100A7 displayed the positive correlation with the degree of differentiation in clinical SCC tissues;[22] we selected three cervical and pharyngeal SCC cell lines with the different degrees of differentiation in order to investigate the role of YAP in S100A7 induction.
