Abstract:
The two nm23 genes, nm23-H1 and nm23-H2, are implicated in the metastatic process and tumor progression in some human tumors. Until now no data exist about nm23 expression in the different types of human renal tumors. To investigate if the nm23 genes play a central role in the progression of renal tumors, we have examined nm23-H1 and nm23-H2 gene expression using Northern-blot analysis and immunohistochemistry. We analysed clear cell type RCC, chromophilic RCC, chromophobic RCC, collecting duct type RCC and renal oncocytomas. Our results indicate that the nm23 genes do not play a central role in the prognosis of renal cell carcinoma in the analysed tumors.
