| Outline of Final Research Achievements |
Clathrin Heavy Chain (CHC) is an endocytosis related protein. We previously reported the immunohistochemical staining of CHC as a histological diagnostic marker of liver cancer or esophageal cancer. In this study, the usefulness for the histopathological diagnosis of pharynx carcinoma, larynx carcinoma, tongue carcinoma, and gingiva carcinoma were investigated. CHC was significantly more strongly expressed in the cytoplasm of malignant legions, than in that of normal tissue or benign lesions. Therefore, the immunohistochemical staining of CHC is a potential biomarker for histological diagnosis of these cancer. Moreover, we synthesized the 12 peptide for serum anti-CHC antibody level. It will be necessary to develop the ELISA method and to evaluate performance for diagnosis of various cancer.
