Abstract

We retrospectively studied the expression of Yes-associated protein (YAP) using immunohistochemical staining in 10 cases of head and neck squamous cell carcinoma with associated perineural invasion. We find that fibroblasts in areas associated with perineural invasion show higher levels of nuclear YAP compared to fibroblasts in the stroma of normal mucosa, with a median cell count of 35.4 per high-power field in the former and 3.9 in the latter. No differences were observed between the expression of YAP phosphorylated at Ser127 in the tumoral stroma compared to that in the normal mucosa, with a median cell count expression of 4.9 in the former versus 5.0 in the latter. Therefore, a strong and increased nuclear YAP expression in fibroblasts associated with perineural invasion in head and neck squamous cell carcinoma suggests that YAP-mediated transcription programs in these fibroblasts may contribute to perineural invasion.
