To investigate EPHA10 protein expression, we examined OSCC cells, a subset of HNSCC, and found variable levels of EPHA10 protein, ranging from 0.69- to 2.12-fold, in the dysplastic oral keratinocyte (DOK) and OSCC cell lines compared with human oral keratinocytes (HOKs; Fig. 1B). Here, EPHA10 is linked to head and neck squamous cell carcinoma.
