Immunohistochemical study on the nm23 gene produce (NDP kinase) in oral squamous cell carcinoma.
The nm23 gene is a potential metastasis suppressor gene originally identified using a murine melanoma cell line. Immunohistochemical investigation on the role of nm23 gene product (nucleoside diphosphate kinase: NDPK) in squamous cell carcinomas of the oral cavity was performed and compared to clinical and histopathological factors. The stainability of NDPK did not correlate to tumour extent, differentiation and mode of invasion. However, the NDPK positive group tended to have a lower frequency of lymph node metastasis, and a better prognosis than the NDPK negative group. Consequently, nm23/NDPK is suggested to be a metastasis suppressor factor that may be useful for predicting tumour metastasis and prognosis in oral squamous cell carcinoma.
