MAPKs' status at early stages of renal carcinogenesis and tumors induced by ferric nitrilotriacetate.

Renal cell carcinoma (RCC) is asymptomatic at early stages, and thus, initial diagnosis frequently occurs at advanced or even metastatic stages, leading to a high rate of mortality. Ferric nitrilotriacetate (FeNTA)-induced RCC model is a useful tool to analyze molecular events at different stages of the carcinogenesis process in vivo. MAPKs' alterations seem to play an important role in the development and maintenance of human RCC tumors.

Characterization of N-diethylnitrosamine-initiated and ferric nitrilotriacetate-promoted renal cell carcinoma experimental model and effect of a tamarind seed extract against acute nephrotoxicity and carcinogenesis.

Renal cell carcinoma (RCC), the commonest malignancy in adult kidney, lacks of early signs, resulting often in metastasis at first diagnosis. N-Diethylnitrosamine (DEN)-initiated and ferric nitrilotriacetate (FeNTA)-promoted RCC may be a useful experimental model, but it is not well characterized. In this study, histological alterations and oxidative stress markers were analyzed at different times throughout RCC development, histological subtype was re-evaluated in the light of current classification, and a tamarind seed extract (TSE) effect was examined.
