Expression of stress-response and cell proliferation genes in renal cell carcinoma induced by oxidative stress.

ABSTRACT: Ferric nitrilotriacetate induces oxidative damage in renal proximal tubules that ultimately leads to a high incidence of renal cell carcinoma (RCC) in rats. In search of genes specifically involved in oxystress-induced carcinogenesis, we have applied a modified fluorescent differential display technique to the tumors and an established cell line as well as their non-neoplastic counterparts. We screened approximately 84,000 products. Reverse Northern blotting confirmed differential expression of 20 transcripts, which showed either significant increase, decrease or lack of expression in the RCCs. Five cDNA clones encoded novel products of unknown function. Fifteen cDNA clones were identified by homology search, which included annexin II, Y-box binding protein, ribosomal proteins, heat shock
