| Research Abstract |
To clarify the disease status of an intractable lesion of oral mucosa, such as oral lichen planus, we have employed the LC-MS/MS analysis. 92 proteins of specific for the oral lichen planus have detected. The data compared with epithelial dysplasia, carcinoma in situ and carcinoma of oral mucosa. We have found different expression pattern of cytokeratins, which is decreased CK13 expression in the oral lichen planus and carcinoma in situ as well as disappearance in the invasive carcinoma. However, CK17 expression increased in a course of progression of the epithelial dysplasia and atypia. This contradict expression pattern of CK is usefulness for the differential diagnosis in these malignant borderline lesions.
