Abstract
Abstract
Background: Dyslipidemia and obesity hypercaloric diet-induced lead to kidney damage. We investigated the effect of curcumin on the expression of proteins related to inflammation, fibrosis, fatty acids metabolism, kidney damage, and morphological changes in the kidney of mice hypercaloric diets-fed.
Methods: Groups of 5-week-old C57BL/6 mice (n=6) were formed: Control (C), High-fructose diet (F), High-fructose diet and curcumin (F+Cur), High-fat diet (HFD), High-fat diet and curcumin (HFD+Cur), High-fat diet and fructose (HFD+F), High-fat diet, fructose and curcumin (HFD+F+Cur), treated for 16 weeks with 30% (w/v) fructose, 60% (w/w) fat and 0.75% (w/w) curcumin. Kidneys were obtained for histomorphological and Western Blot analysis.
Results: Curcumin prevented TNF-α overexpression in the F and HFD+F groups. VLCAD expression was higher in the F, HFD, and HFD+F groups. PPARγ expression was lower in the F+Cur, HFD+Cur, and HFD+F+Cur groups. Curcumin prevented overexpression of CPT1 and KIM1 in the HFD+F and HFD groups. Curcumin prevented morphological lesions, fibrosis, and lipid deposition hypercaloric diet-induced.
Conclusion: Chronic consumption of hypercaloric diets causes inflammation, fibrosis, and lipid deposition in the kidney. It is suggested that curcumin differentially modulates kidney injury as a function of the damage induced by the high-fat/high-fructose diet.
