摘要

Recent advances in gene expression profiling have led to the development of comprehensive databases which can be queried in various manners. In the present report, we have taken a list of genes previously associated with angiogenesis, either in in vivo or in in vitro models, and queried a commercial database established by GeneLogic((R)) to determine the relative expression of these candidate genes in normal kidneys and in renal cell carcinomas (RCC). We identified a number of genes, including CXCR4, matrix metalloproteinase 9, thrombospondin 2, and vascular endothelial growth factor, that were highly expressed in RCC versus normal tissue. One gene, hevin, appears to be selectively upregulated in RCC in contrast to downregulation of this gene in lung and colon tumors. This approach provides a powerful means to identify potential markers of tumor vascularization.
