The rest clones were the known genes and some of them were RCC-related, including vascular en-dothelial 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. Immunohis-tochemical 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.展开更多
