10.22376/ijpbs.2019.10.1.p1-12 Volume 7 Issue 3 2016 (July - September) The success of dysregulated NF-κB activated genes inhibition by phytosterols has encouraged in targeted therapy of chronic inflammatory diseases. The objective of this current study was to examine the involvement of β-sitosterol in the inflammatory cascade against renal carcinogen. Renal cancer was induced by single intraperitoneal injection of N-diethylnitrosamine (200 mg/kg bw) and twice weekly administration of ferric nitrilotriacetate (9 mg Fe/kg bw) for 16 weeks. The chemopreventive potential of β- sitosterol against renal carcinogen was studied in terms of inflammatory markers. Our study showed that oral administration of β-sitosterol (20 mg/kg bw) pretreatment significantly (p lessThan 0.05) downregulated the expression of inflammatory markers which have been modified by Fe-NTA. We found that, the renal protective effect of β-sitosterol is associated with the inhibition of the inflammatory cascade through the down regulation of NF-κB activation, TNF-α, iNOS and COX-2 production. Antiinflammatory property of β- sitosterol could provide the link to understand its chemopreventive mechanism in experimental carcinogenesis. R. SHARMILA, G.
