Galangin attenuates adenine-induced chronic renal failure by inhibiting transforming growth factor beta (TGF-β) expression

Introduction: Galangin (3,5,7 tri-hydroxy flavone), naturally active flavonoid is derived from the rhizomes of Alpinia officinarum is proven to be effective antioxidant, anti-inflammatory, anti-cancer. However, protective effects of galangin in chronic renal failure (CRF) is not explored. Objectives: This study is aimed to investigate the nephroprotective activity of galangin in adenine-induced CRF rats. Materials and Methods: Adenine induced rats were administered galangin 20 mg/kg and 40 mg/kg body weight (BW) serum renal and hepatic parameters, and renal antioxidant-lipid peroxidation parameters, histological studies were carried out. The mechanism of action was investigated by flow cytometry. Results: Galangin has normalized serum renal and hepatic parameters, reduced oxidative stress and lipid peroxidation. Histopathology confirms nephroprotection. The percentage number of cells expressing transforming growth factor beta (TGF-β) was reduced with galangin treatment. Conclusion: Galangin exerts nephroprotection in adenine induced CRF by inhibiting TGF-β expression.
