To isolate the over-expressed genes in human renal cell carcinoma (RCC) and analyze its molecular basis of carcinogenesis, we used the mRNA from human RCC tissues as tester and that from the matched normal kidney tissues as driver to construct the suppression subtractive hybridization library. 379 of the subtracted clones were arrayed onto a nylon membrane and the over-expressed genes were then screened by hybridizing the filter with radioactively labeled cDNA from RCC and matched normal kidney tissues. 67 clones over-expressed in RCC by a factor of 6 or more were sequenced and its identities were analyzed in GenBank database. 4 clones were previously unknown fragments and 2 clones represent KIAA genes. The rest clones were the known genes and some of them were RCC-related, including vascular endothelial growth factor, vimentin and tissue factor. Most of the known genes were the RCC-related genes previously unknown, including zinc ribbon domain-containing 1 protein (ZNRD1), pituitary tumor transforming gene1 (PTTG1). Northern blot and semi-quantitative RT-PCR confirmed that the mRNA levels of the 3 novel fragments and 1 KIAA and 3 known genes were significantly higher in RCC than in the matched normal kidney tissues. Immunohistochemical and Western blot analysis for PTTG1 and ZNRD1 revealed increased protein level in RCC. The over-expressed genes in RCC are the potential molecular targets for diagnosis and therapy and it is very important to understand the molecular mechanism of RCC through the profile of over-expressed genes.
