| Research Abstract |
Expression of transporters of scintigraphic agents on cell membrane was evaluated immunohistochemically using patients with squamous cell carcinoma in oral lesion and animal models with squamous cell carcinoma. Transport proteins of glucose transporter, P-glycoprotein, Na/K-ATPase and L-amino acid transporter found on cell membrane and showed a distinct correlation with tumor malignancy, tissue differentiation and accumulation of nuclear agents in tumor cells. These results indicated a possibility that transport proteins were useful as tumor marker for diagnosis of malignant tumors.
